Recorded test data are presented for Test S-28-3 of the Scmiscale'Mod-1 steam generator tube rupture test series. These tests are among several Semiscale Mod-1 experiments conducted to investigate the thermal and hydraulic phenomena accompanying a hypothesizedloss-of-coolant accident in a pressurized water reactor (PWR) system.

Test S-28-3 was conducted from initial conditions of 15 621 kPa and 555 K to investigate the response of the semiscale ~ o d - 1 ' system to a depressurization and reflood transient following a simulated doubleended offset shear of the broken loop cold leg piping. During the test, cooling water was injected into the cold leg of the intact and broken loops to simulate emergency core coolant injection, a ,PWR. Twelve steam generator tube ruptures were simulated by a controlldd iii,eLtidn f r o d a heated accu~nulalur illlo U . L ~ i ~ ~ t a c t loop hot leg.

The pilrpnse of this report is to make available the uninterpreted data from Test S-28-3 foi future data analysis and test rkp6rting aclivitie~! Tlle data, presenletlill Llle form of graphs in engineering units, have been analyzed only to the extent neceSSBrjs TO ensure that they are reasonable and consistent.

SUMMARY

Test S-28-3 was performed as part of the Semiscale Mod-1 portion of the Semiscale Program conducted by EG&G Idaho, Inc. for the United States Government. This test is .

part of the steam generator tube rupture test series (Test Series 28) performed to investigate the response of the Mod-1 system to steam generator tube ruptures during a hypothesized loss-of-coolant accident (LOCA). The test objective specific to Test S-28-3 was to determine the lower limit on the range of steam generator tube ruptures over which high peak cladding temperatures can occur. Hardware configuration and test parameters were selected to yield a system response that simulates the response of a pressurized water reactor during a hypothesized LOCA with subsequent refill and reflood.

Test S-28-3 utilized the Semiscale Mod-1 system equipped with a pressure vessel with a 40-rod electrically heated core; an intact loop with pump, steam generator, and pressurizer; a broken loop with simulated pump, simulated steam generator, and rupture assemblies; and a pressure suppression system with header, pressure suppression tank, and heated steam supply system. High and low pressure coolant injection pumps and a coolant injection accumulator were ' provided for each system loop. An additional injection was provided for the intact loop hot leg. The intact loop hot leg injection flow rate was set to simulate the rupture of 12 steam generator tubes. For Test S-28-3 four heater rods were intentionally unpowered to simulate the effects of control rod guide tubes and the power in three heater rods was increased to produce a slightly peaked power profile.

The test was conducted from initial conditions of 15 621 kPa and 555 K (at the intact loop cold leg vessel inlet) with a simulated full size (200%) doubleended offset shear of the broken loop cold leg piping at an initial core power level of 1.40 MW, and an initial core inlet flow rate of 9.07 Q/s. The instantaneous offset shear of the broken loop cold leg piping was simulated by simultaneous (within 10 ms) actuation of the rupture assemblies. After initiation of blowdown, power to the heated core was reduced to simulate the predicted heat flux response of nuclear fuel rods during a LOCA. Blowdown was accompanied by simulated emergency core coolant injection into the cold leg piping of the intact and broken loops. This injection was followed by a controlled injection from a heated accumulator into the intact loop hot leg to simulate steam generator tube ruptures.

Test S-28-3 was generally conducted as specified. Conditions which did not conform to the specified test configuration were considered acceptable for analysis purposes within the test objectives. The instrumentation used generally functioned as intended. Of 220 measurements taken, 2 16 produced usable data.

EXPERIMENT DATA REPORT FOR SEMISCALE MOD-1

TEST S-28-3

(STEAM GENERATOR TUBE RUPTURE TEST)

I. INTRODUCTION

The Semiscale Mod-1 experiments represent the current phase of the Semiscale Program conducted by EG&G Idaho, Inc. for the United States Government. The program, which is sponsored by the Nuclear Regulatory commission through the Energy Research and Development Administration, is part of the overall program designed to investigate the response of a .pressurized water reactor (PWR) system to a hypothesized loss-of-coolant accident (LOCA). The underlying objectives of the Semiscale Program are to quantify the physical processes controlling system behavior during a LOCA and to provide an experimental data base for assessing reactor safety evaluation models. The Semiscale Mod-1 Program has the further objective of providing support to other experimental programs in the form of instrumentation assessment, optimjzation of test series, selection of test parameters, and evaluation of test results.

Test S-28-3 was conducted June 30, 1977 in the Semiscale Mod-1 system as part of the steam generator tube rupture test series (Test Series 28). This series was designed to obtain thermal-hydraulic response data from blowdown, refill, and reflood transients in a simulated nuclear reactor with a heated core to study system response during a LOCA with steam generator tube ruptures. The specific objective of Test S-28-3 was to determine the lower limit on the range of steam generator tube ruptures over which high peak cladding temperatures can occur. The intact loop hot leg injection flow rate was set to simulate the rupture of 12 steam generator tubes. Hardware configuration and test parameters were selected to yield a system response that simulates the response of a PWR to a hypothesized LOCA wilh subsequent refill and reflood.

The purpose of this report is to present the test data in an uninterpreted but readily usable form for use by the nuclear community in advance of detailed analysis and interpretation. Section 11 briefly describes the system configuration, procedures, initial test conditions, and events that are applicable to Test S-28-3; Section I11 presents the data graphs and provides comments and supporting information necessary for interpretation of the data. A description of the overall Semiscale Program and test series, a more detailed description of the Semiscale Mod-1 system, and a description of the measurement and data processing techniques and uncertainties can be found in Reference 1.

11. SYSTEM, PROCEDURES, CONDITIONS, AND EVENTS FOR TEST S-28-3

The following system configuration, procedures, initial test conditions, and events are specific to Test S-28-3 as indicated.

1. SYSTEM CONFIGURATION AND TEST PROCEDURES

The Semiscale Mod-1 system used for this test consisted of a pressure vessel with internals, including a 40-rod core wit11 3G electrically hcoted rods; an intact loop with steam generator, pump, and, pressurizer; a broken loop with simulated steam generator, simulated pump, and two rupture assemblies; coolant injection accumulators for Uie cold legs of the intact and broken loops, and a heated accumulator for the intact loop hot leg; high and low pressure injection pumps for each of thc system loops; and a pressure suppression systcm with a suppression tank, header, and heated steam supply system. For Test S-28-3, the volume of the lower plenum was reduced to 0.014 980 m3 by the addition of a metal fdler piece. Semiscale Mod-1 experirnerltal system configuration information is described further in Reference 1. Figures 1 and 2 show the system configuration for Test S-28-3.

For Test S-28-3,33 rods of the 40-rod electrically heated core were operated at a peak power density of approximately 35.05 kW/m, three rods (Rods D4 , E4, and E-5) were operated at a peak power density of 36.88 kW/ni to yield ii slightly peakcd power profile, and four rods (Rods C-3, U-5, F-3, and H-6) were unpowered to sinlulatc thc cffcct of control rod guide tubes. The resulting total core power was approximately 1.40 MW.

In preparation for the test, the accumulators for the intact and broken loop cold legs were filled with treated demineralized water, drained to the specified initial levels, a d

pressurized with nitrogen to 4223 kPa. The steam generator rupture system accumulator for the intact loop hot leg was filled with treated demineralized water, drained to the specified initial level, heated to 549 K, and pressurized to '1570 kPa. The systern was riled with treated demineralized water and vented a l stl-attgic points tu cnsuro a liquid full systcm. Prior to warmup the system was pressurized to check for leakage, system instrumentation was checked, and transducer readings were initialized. warmup to initial test conditions was accomplished with the heaters in the vessel core. Heatup of the broken loop piping was accnmplinhcd with bypass lines which served tn allow circulation through the brvkerl loop. During warmup, the purification and sampling systems were valved into the primary system to maintain water chemistry requirements and to provide a water sample at system conditions for subsequent analysis. At 55.6-K-temperature intervals during war~nup, detector readings were sampled to allow the integrity of the measurement instrumentation and the operability of the data acquisition system to be checked.

Prior to the initial core power level being established, the pressure suppression system was pressurized to 227 kPa with saturated steam from the steam supply system. After the core power was increased to 1.40 MW, initial test conditions were held for 360 s to establish

equilibrium in the system. At the end of this period all auxiliary systems including. the bypass .lines were isolated tq prevent blowdown through those systems.

.

The system was successfully subjected to a simulated doubleended cold leg break through two rupture assemblies and two b1.owdown nozzles, each having a break area of 0.000 243 m2. Pressure to operate the rupture assemblies and initiate blowdown was taken .

t

from an acculnulator system filled with watcr and pressurized to 15 600 kPa with gaseous nitrogen. Immediately (within 0.02 s) after initiation of blowdown, the lines to the accumulator were again isolated. The effluent from the primary system was eje~led h t o the pressure suppression system which was vented to maintain a constant pressure of 227 kPa. At blowdown, power to the primary coolant circulation pump was reduced and the pump was allowed to coast down to a speed of 1470 rpm which was maintained for the duration of the test. During the blowdown transient, power to the electrically heated core was automatically controlled to simulate the thermal response of nuclear heated fuel rods.

schematic.

For Test S-28-3, the coolant injection systems were arranged to discharge into both system loops at the cold leg injection points (Spool 14 and Spool 42). The high pressure coolant injection pumps were started immediately after initiation of blowdown (0 s) and continued to the end of the test (640 s). Low pressure coolant injection was initiated 25 s after blowdown at a system pressure of 1103 kPa and continued until test termi- nation (640 s). Coolant injection from the intact loop accumulator (CI-T-1) started 16.7 s after blowdown, and nitrogen discharge began 52 s after rupture and was terminated 84 s after blowdown. The broken loop accumulator (CI-T-2) began injection 3 s after blowdown, nitrogen discharge began 27 s after .rupture and was terminated 65 s after blowdoWn. The steam generator rupture system accumulator (CI-T-3) began injection at 39 s at a system pressure of 480 kPa and was terminated 640 s after blowdown.

111. DATA PRESENTATION

The data from Semiscale Mod-1 Test S-28-3 are presented with brief comment. Processing analysis has been performed only to the extent necessary to obtain appropriate engineering units and to ensure that the data are reasonable and consistent. In all cases, in converting transducer output to engineering units, a homogeneous fluid was assumed. Further interpretation and analysis should consider that sudden decompression processcs such as those occurring during blowdown may have subjected the measurement devices to nonhomogeneous fluid conditions.

The performance of the system during Test S-28-3 was monitored by 220 detectors. The data obtained were recorded on both digital and analog data acquisition systems. The analog system was used to provide better resolution capabilily (needed as input Po various data analysis codes). The long-term data (-32 to 640 s) presented in this report were recorded at an effective sample rate of 1.369 points per second. Long term plots are given for -20 to 600 s rather than for the full 640-s recording time to provide better resolution. Short-term data and plots (-6 to 42 s) were recorded at an effeclive sa~illlple~ratc of 19.1 7 points per second.

The data are presented in some instances in the form of composite Wphs to facililale comparison of the values of given variables at several locations. The scales selected for the graphs do not reflect the obtainable resolution of the data. (The data processing techniques are described turther in Reference 1 a d Appcndix A).

Figures 3 through 8 and Table V provide supporting information for interpretation UP the data graphs shown in Figures Y through 352 and pruvidt: ~eldlire locations of all detectors used during Test S-28-3. Table V groups the measurements according to measurement type; identifies the specific measuremefit locativri a d iailge of thc detector and actual recording range of the data acquisition system; provides brief comrncnts regarding the data; and references the measurements and commejlts to the corresponding figure. Figures 9 through 352 present all the blowdown and reflood data obtained. Time zero on the graphs is the time 01 ~upture initiation. Appendix A provides information explaining the data acquisition system capabilities. Appendix B provides information explaining posttest data processing for data conversivli into engineering units and data adjustments. Presented in Appendix C is an analysis of selected data which provide a guide to the iincertainty associated with data measurements in the Semiscale Mod-1 system.

DATA ACQUISITION SYSTEM CAPABILITIES

The Semiscale Mod-1 system provides for the acquisition, processing, and presentation ,of test data. Detectors, signal conditioners, signal processors, and recording and display equipment comprise the test data system. The data obtained are principally recorded on an on-line digital system. Selected data channels are also recorded on an analog system.

The on-line digital system is called the digital data acquisition and processing system (DDAPS). The DDAPS has dual and single speed capabilities with identical storage and data output limitations. The dual speed mode is used to ex'tend the recording time when obtaining high frequency data.

From each of up to 240 data channels, the test data system stores 20 blocks of data. Each block of data contains 920 words (each word is the abscissa and ordinate of a data point) of digital information. These 920 words represent a fixed storage display.

The maximum measured.throughput rate for the system is 24 000 words per second. This throughput rate can be reduced in increments of 100 words per sccond. The throughput rate, the number of data channels recorded, and fmed display of 920 words per block determine the time base for displaying the data.

After .the data have been stored, data reduction can be made for presentation and analysis .purposes. Because of hardware limitations and aesthetic considerations of data presentation, only certain time bases are used when the data are reduced. For data displayed from -20 to 300 s, the recorded data are made to occupy a 320 s span yielding a time base of 16 s, which is the 320 s span divided by the 20 blocks of recorded data.

Generally, 920 words from a given data channel are displayed in the nominal time base of 16 s. Integral (1 to 20) multiples of 16 s may be used as variations on the nominal time base. Because the output is fixed at 920 words, data compression is done by averaging adjacent data points to give the desired compression.

POSTTEST ADJUSTMENTS TO DATA FROM SEMISCALE MOD-1

TEST S-28-3

Many of the transducers used in the Semiscale Mod-1 system exhibit significant sensitivity to one or more spurious inputs. Strain gage bridge circuits used in pressure transducers, differential pressure transducers, and drag discs are sensitive to changes in ambient temperature. Differential pressure cells are also sensitive to changes in system pressure. Photomultiplier tubes used as gamma ray detectors in the density transducers are sensitive to temperature changes, as well as to random variations in the locations of the radiation sources. Core power measurements. depend' on a calibrated resistor, whose. resistance changes in value as a function of time and power level as it heats up.

Although the errors introduced into the data by spurious secondary inputs generally do not exceed the specified error ranges of the transducers, significant improvement in measurement accuracy can be achieved if the secondary sensitivity can be identified and removed. In the case of the drag discs, corrections are absolutely necessary because the signal due to temperature fluctuations can exceed that due to flow by several hundred percent. Since the exact values of the spurious inputs to which different transducers might be sensitive cannot often be easily predicted and are sometimes inconvenient to measure, secondary effects have been accounted.for by correcting the data after the test rather than by using elaborate real time programs in the data acquisition system computer. The methods and results of the posttest data correction analysis for Test S-28-3 are presented in the following paragraphs and tables.

1. PRESSURE MEASUREMENTS

Corrections to pressure transducer measurements in the main system loop are based on data taken from the standard reference ( ~ e i s e ) gauge at Spool 4, taken 15 s before initiation of blowdown and at 300 s after initiation of blowdown. The pressure readings are adjusted to account for pressure variations around the main loop, using the readings of nearby differential presslire cells. A linear correction is then applied to the pressure data to match the data to the calculated reference data at the two specified time points.

Correction of the steam generator secondary pressure (PU-SGSD) measurement is done in the same manner as for the main loop pressures using a Heise gauge installed expressly for this purpose. The data from the pressure transducer for the pressure suppression system (P-PSS) are corrected to match the process instrumentation at preblawdnwn conditions.

Pressure measurement corrections are performed using the data acquisition system (DAS) computer using the following equation:

where

F1(t) = corrected data

F(t) = raw data

Co = offset, kPa

C1. = scaling factor.

The values of the offset and scaling factor are given in Table B-1.

DIFFERENTIAL PRESSURE MEASUREMENTS

. . , .

Pressure sensitivity in the .differential pressure cells in the main system. loop is determined from the pretest system pressure check; Digital data are recorded for all measurements at ambient .temperature, with no system flo.w, at pressures of ambient, 1780, 5 1 10, 7 160, 8820, 12 220, and 15 500 kPa. The output of the differential pressure cells is plotted against system pressure, .with. the resulting plots used to describe the pressure response of the transduccrs.

Pressure cell ambient offsets are evaluated ushg a posttest, system drained digital data scan. The measured transducer outputs are compared with .values calculated from the differences in standing leg heights for the sense lines to each pressure cell. . The ,.. difference between the measured value and the calculated value is the ambient offset. .,

For some differential pressure ieasurements, other references are used. The liquid level measurements in the intact loop accumulator (DPU-ACCl-TB) and the broken loop accumulator (DPB-ACCZTB) are referenced to calculated values based on geometrical considerations at the time when the water is depleted from the accumulators and gas flow begins. The reading from the steam generator discharge venturi (DPU-SG-DISC) is shifted to read zero after flow is stopped.

In correcting differential pressure data for pressure sensitivity, the data are initially corrected for errors in amplification and ambient offsets. The data are then corrected for pressure sensitivity to arrive at the final values. Corrections were made using the following equations :

F 1 ( t ) = K [ F ( t ) ] + Co

where

F1(t) = data corrected for amplification and ambient offsets, kPa

K . = amplification factor

F(t) = raw data, kPa

Co, = ambient offset, kPa

F f l ( t ) = F 8 ( t ) + C1 for t < tl

where i takes on values 1 to,n-1

F M ( t ) = F 1 ( t ) + C, for t > t,,

where

t - - time

F1'(t) = final corrected data

Ci and t l = correclions a ~ i d t h e points.

The values of the constants are given in Table B-11.

3. MOMENTUMFLUXMEASUREMENT

The tempkrature sensitivity of drag discs is determined from pretest warmup data taken at temperatures from ambient to 478 K with no system flow. Some drag discs are also pressure sensitive and are evaluated at pressures from ambient to 15 5 10 kPa with no system flow. The temperature and pressure sensitivity are removed before the data are converted to momentum flux. The temperature and pressure at each drag disc are taken' from the signal of a nearby thermocouple and pressure transducer. Slight corrections are also made at this time for errors in setting the transducer output to zero at ambient conditions. corrections are made using the following equation:

F 1 . ( t ) = F(t) + Co - Ti T(t) - Pi P(t)

where

Fi(t) = corrected data, DAS volts

F(t) = raw data, DAS volts

Co ' = ambient offset, DAS volts

Ti = temperature sensitivity, DAS volts/K

T(t) = temperature data from the transducer used for tempera- ture sensitivity correction, K

Pi = pressure sensitivity, DAS volts/kPa

P(t) = pressure data from the transducer used for pressure sensitivity correction, kPa.

Values of the constants are given in Tablt: B-111.

4. DENSITY MEASUREMENTS

Density calculations are based on the voltage output of the photomultiplier tubes in the gamma-attenuation densitometer assemblies. The equation used for converting voltage to density is as follows:

where

p = the density in kg/m3

C = a constant based on the length of the gamma beam path

D = a theoretical voltage for zero attenuation inside the vessel

A = an amplification factor

B = a biasing factor

F(t) = the transducer voltage output. -

Constants A and R are adjusted to match the final data to density values calculated from measured pressure and temperature values at the preblo.wdown and postdrain conditions, effectively giving the data an in-place calibration. The values of the constants for various transducers are given in Table B-IV.

The density measurements GVLP-172HZ and GV-COR-ISOHZ use amplifiers which precalculate the logarithm function, and hence have a simpler conversion formula:

Some density measurements are obtained using a two-beam gamma densitometer which operates on the same basic principle of gamma attenuation as does the single-beam gamma densitometer. Each beam originates from the same gamma source and is allowed to pass through separate portions of the piping cross-sectional flow area to obtain an average density measurement in that particular region. The geometrical relationship of the gamma beam path through the piping and geometrically related variables used for processing of data from a two-beam gamma densitometer are shown in Figure B-1 .

m e average density measured by each individual gamma beam is obtained using the same equation as is used for the single-beam gamma densitometers. Values for the constants for' the single-beam density measuremefits obtained with the two-beam gamma densi- tometers .are presented in Table B-IV along with the constaqts for single-beam gamma Sensitometers.

In the Semiscale Mod-1 system, two.-beam gamma densitometers provide added information which allows the calculation of a better average density than that obtained from a single'beam. A mathematical model is used for processing the two-beam data to obtain the provided average density information. The processing method used is based on a .froth-water model coupled with information from the two individual gamma beams and related beam path and piping cross-sectional geometry. The resulting information is recorded and reported under the density measurement identification ending with a "C", for example, GB-2 1 C.

F i g . B-1 Geometry used f o r processing o f densi ty data obtained from two-beam gamma densitometers.

The use of the froth-water model for obtaining average density from a two-beam gamma densitometer is based on observations indicating that flow regimes in the Semikale Mod-1 system can be modeled by a layer of water on the bottom of the pipe with a degree of froth on the surface. For homogeneous flow conditions such as a l l froth or all liquid the model remains valid.' At any point in time slug flow is also modeled. The froth-water model does not model annular or inverted annular flows very well. However, these flows are not expected to exist for 'significant portions of a Semiscale Mod-1 system blowdown in horizontal piping. Density gradients from the top to the bottom of the pipe may exist showing no distinct location change from water to froth. This flow is neither, totally homogeneous nor stratified, but the froth-water model does provide an adequate approximation of the average density characteristic of this flow pattern.

. The average density obtained by using the gamma beam geometry shown in Figure B-1 and by applying the froth-water mode.1 is given by

where

- P = average cross-sectional density

p1 = average density measured by the upper gamma beam (measures the froth density)

pw = density of liquid water (at local system conditions)

a.~f = 1 +. (1 /2n) (sinpg) = froth fraction.

Thc nngle which j3 represents is s h o w in Fig~~rr, 8-1. Values for fl are obtaincd as follows :

where

h = H 2 P 2 - P1 b = cos 0

Pw - "1

where .

H = Q,cos 8 (IZ, and 6, are defined in Figure B-1 )

D = piping inside diameter . ..

. . p* = the average density measured by the lower gamma beam. . .

Average density is not cdculated using theatwo-beam froth-water model when the angle 8 is not favorable due to system hardware restrictions in pqsitioning. the source. '1Be froth-water model requires separate density sampling in both the upper and lower port'ions of the piping cross section. . -

APPENDIX C

SELECTED DATA WITH ESTIMATED TOTAL ERROR

BANDS FROM SEMISCALE MOD-1 TEST S-28-3

Analysis has been performed on selected data from Test S-28-3 to provide a guide to the uncertainty associated with data measurements in the Semiscale Mod-1 system. The end result of the analysis is presented as error bands about the measured data which represent a 95% confidence level.

The error bands are obtained by combining uncertainties obtained from analysis of the data itself (random error) and engineering analysis of the measurement system (engineering error). The procedure by which error bands were established for the data presented in this appendix is described in the following paragraphs.

The data trace under analysis wits empirically fitted with a linear difference equation, which was subject t o a white noise input at each sampling time point. The objective of the empirical fitting procedure was to characterize the white noise, which was taken to represent the random error. The procedures for fitting the difference equation are discussed in depth in Reference C-1. A data trace was often segmented and different equations were fitted to each segment with statistical correlations between successive observations accounted for by the fitting procedure. The white noise input was assumed to arise from a normally distributed population. The standard deviation.of the white noise, as found during the fitting procedures, was taken as an estimate of the random error standard deviation and is shown in Table. C-I. The data traces of the error band analysis are shown in Figures C-1 through C-3 8. . .

Other errors in the data exist because of such factors as variability in installation procedures and techniques, calibration errors, variability in materials, and temperature and pressure sensitivities. These errors and the procedures for estimating them are discussed in Reference C-2. They are referred to as engineering-errors and the estimates are largely subjective. Because of the continuing effort to improve the accuracy of the measured data, such as through the use of better transducers, better signal conditioning and processing equipment, and better calibration and installation techniques, the engineering errors for data from most of the transducer systems have changed from those published in Reference C-2. Table C-I1 provides a summary of engineering error values obtained from current analysis techniques as applied to the data presented herein.

In addition to the normal hardware and installation related sources of engineering error, a significant measurement uncertainty results when the current transducer systems are subjected to separated t w ~ - ~ h a s e flow regimes during the course of the blowdown transient. Accordingly, for those data affected (fluid density, momentum flux, volumetric flow, and mass flow), which are presented in this appendix, a more extensive assessment was conducted for additional engineering error due to flow regime effects. Table C-I11 identifies the data analyzed and the period in the blowdown process for which flow regime errors were included as a part of the total engineering error. The time of occurrence of separated two-phase flow and the resulting effect on the uncertainty of the data were evaluated by considering, on an individual basis, each detector output with reference to indications by other auxiliary measurements.

The gamma densitometer density measurement data are affected by two-phase separated tlow regimes. 'l'he resulting transducer output is a measurement of the average attenuation of the gamma beam through the measured medium. The beam attenuation, in turn, is interpreted through physical relationship to be a measure of the average density along the beam path. When stratified type flow was considcrcd prcsent, thc gamma beam attenuation was considered to be a result of a liquid layer and steam at system conditions. With this assumption and the system geometry, a void fraction was calculated and a new "effective" average density was calculated. The difference between the average density based on the assumption of homogeneous conditions and the average density for stratified conditions was considered to be the error.

Momentum flux measurement uncertainties for two-phase flow regimes present the most difficult engineering evaluation problems. The drag target and arm location, degree of flow stratification, transducer temperature sensitivity, and slip ratios all combine to produce possible flow regime errors ranging from a small fraction of the transducer output value to multiples of it. Therefore, the error values were obtained, where possible, through use of the observed discrepancies between the momentum flux and turbine flowmeter data in combination with system pressure measurements and the analysis of system fluid density measurements.

The flow regime errors of the turbine flowmeter were estimated by calculating a void fraction and the cross-sectional liquid and steam flow areas for stratified flow. This calculation was accomplished using methods similar to those used to calculate the average

density for stratified flows. A simple model was used to equate the forces on the turbine withthe assumption of a known void fraction, stratified flow, known component densities, and slip ratio greater than unity. This process provided phase velocities. With the phase densities, velocities, and void fraction, a volumetric flow rate could be calculated. The difference between this value and the measured value was considered to be the error.

The overall standard deviation of a data point is taken as the root mean of the sum of the random error variation and the total engineering error variance; that is, '

where

uo = overall standard deviation of a data point

U R = random error standard deviation

UE = engineering error standard deviation.

The error bands for the data are computed about the value given by the fitted difference equation yi at time point, i; that is,

e r r o r band = yi + 1.960, (C-2)

With due regard to the fact that o~ has been estimated subjectively, the error band may be interpreted as an approximate 95% confidence interval within which any true value of the measured variable is consistent with the data.

On certain occasions, the symmetrical error band given by Equation (C-2) is not appropriate. On those occasions, asymmetrical error bands were computed. (That is, with the width being greater on one side of yi than on the other.)

Finally, the original data trace, along with its error band from Equation (C-2), was 1- input to a computer plot package. The resulting. plot contained the actual data trace surrounded by an error band derived both from random error and engineering error considerations. The indicated error bands after thermocouple dryout occurred for the fluid

, : , .. temperature measurements should be ignored. Error bands for these segments of the data were not obtained and bands only appear because of limitations in the plotting package. 0. .
