2.2 02818905-QSR COMPONENT REVIEW
A review of the High Range Area Monitor System list of materials was made for major
assemblies that were previously environmentally qualified by GA-ESI report 02818905-QSR.
The TVA tag numbers and their representative components were qualified as part of the GA-ESI
report 02818905-QSR. Specifically, the RD-23 detector (GA-ESI P/N 03602062-001), a NIM
Bin assembly (GA-ESI P/N 02810279-001), and an RP-2C module (GA-ESI P/N 02810410-002)
were qualified. The RD-23 detector being qualified is that same as that qualified by 02818905-
QSR and its qualification basis will not be repeated in this report. The RP-2C module has been
replaced by an RM-1 000 and I/F converter and will be qualified by this report.
2.3 QUALIFICATION BASIS
This section describes the basis for the qualification of the High Range Area Monitor System.
The detectors are qualified for a Harsh environment and the Control Room components for a
Mild environment. Therefore, the detectors are qualified for normal, abnormal, accident, and
post-accident service conditions. The Control Room components are qualified for normal and
abnormal service conditions, but they must operate through the accident and post accident
periods in those service conditions.
For Mild environments, GA-ESI type tests computer based assemblies that are designed and
manufactured by GA-ESI to abnormal extremes to demonstrate performance over the
temperature and humidity range that the assemblies may experience in service. Certain other
assemblies, whose performance may be affected by extremes, designed and manufactured by
GA-ESI, are also tested at temperature and humidity extremes. All other components and
assemblies are selected for the generic service conditions and approved through a design
review and commercial grade dedication process (in accordance with GA-ESI procedure OP-
7.3-240). Performance and functionality of the monitor assembly are demonstrated by the final
Acceptance Test Procedure (ATP). A certificate of compliance is provided with the accepted
04038903-7SP
Rev C Page 9
25402-011 -VIA-HARA-001 90-001
assembly. Components and modules that have a life less than 40 years are identified in
Section 4, Replacement Schedule.
For Harsh environments, GA-ESI type tests all components for normal, abnormal, accident, and
post accident service conditions to demonstrate that those components will perform their safety
functions.
The detectors, located in the Upper and Lower Containment Compartment environment, have a
normal radiation total dose greater than GA-ESI levels of qualification. A radiation review of
each part in the assemblies was performed using TVA RIMS report #B43'860721903 as the
basis for qualifying the equipment to higher levels of radiation. The results of that review are
given in GA-ESI report 02818905-QSR.
Environmental Qualification Summary Table 2-1 identifies the assemblies that are qualified by
test and the test article that was utilized to demonstrate that qualification. The subsequent
subsections describe that testing performed for each assembly and compare the test article with
the assembly being qualified.

3 SEISMIC QUALIFICATION BASISThe seismic qualification of the High Range Area Monitor System, GA-ESI P/N 04034101-001,
is based on previously completed seismic tests and analysis. This section describes the basis
for the seismic qualification. The monitor is Seismic Category I.
3.1 SEISMIC REQUIREMENTS
The High Range Area Monitor System is safety related and is required to operate during or after
an earthquake. For qualification by random is used to
ensure that the Test Response Spectra envelopes the Required Response Spectra. For
analysis the values of ZPA and peak acceleration shall be based on
3.1.1 Plant Equipment Seismic Requirements
The requirements for the seismic qualification of the High Range Area Monitor RD-23 detector
located in the plant are found in GA-ESI document 04038903-QSR, Figures 3-4 through 3-7.
The ZPA and peak acceleration values for plant equipment are given in Table 3-1. The values
provided in Table 3-1 represent the highest accelerations of both the Upper and Lower
Containment Compartments. East-West spectra were provided by the customers Figure
C1.180. Since the detector is attached to the building walls, the ARS defines the RRS.

For comparison of the Test Response Spectra (TRS) with the Required Response Spectra
(RRS) a simplified RRS curve is constructed using the information given in GA-ESI document
04038903-QSR Figures 3-4 through 3-7 and Table 3-1, as follows. The governing North-South

provided by the customer.
* Vertical: The spectrum given in GA-ESI document 04038903-QSR Figure 3-4 and 3-6
are to envelope the RRS shown in those figures. The vertical
RRS is shown in Figure 3-1 (Data in Table 3-2).
* Horizontal: The spectra given in GA-ESI document 04038903-QSR Figures 3-5 and 3-
7 are broadened, and simplified to envelope the north-south RRS in those figures. The
horizontal RRS is shown in Figure 3-2 (Data in Table 3-3).

3.2 COMPONENT REVIEW
A review of the High Range Area Monitor System list of materials was made for major
assemblies that were previously seismically qualified by GA-ESI report E-115-0459. Major
assemblies for this monitor have not been qualified by GA-ESI report E-1 15-0459, therefore,
this qualification basis is for all assemblies and components.

3.3 QUALIFICATION BASIS
This section describes the basis for the seismic qualification of the High Range Area Monitor
System. The monitor system is qualified as seismic Category I and is required to be functional
during and after a seismic event.
GA-ESI seismically qualifies radiation monitoring systems by test and structurally by analysis.
Generally, components and assemblies that are tested are tested functionally as well as
ensuring the seismic adequacy of the structure. GA-ESI has tested the radiation monitoring
systems using test methods. Conservative analysis is
performed
in
GA-ESI document 04038903-QSR.
The Seismic Qualification Summary Table 3-7 identifies the assemblies that are qualified by test
or analysis. The test article that was utilized to demonstrate qualification is provided as well as
the test report. The subsequent subsections describe the testing or analysis for each assembly
and compare the test article or the structure analyzed with the assembly being qualified.

3.3.1 NIM Bin Assembly
The Control Room NIM Bin Assembly (GA-ESI P/N 04030801-001) contains RM-1000 and I-F
Converter Modules as well as the power supply assembly. The components are qualified
individually by test and analyses of similar components discussed in the following subsections.
The NIM Bin Assembly is similar to the NIM Bin Assembly used for the qualification testing of
the original 24 volt power supply, the RM-1 000 and the I-F Converter Modules.
3.3.1.1 NIM Bin Assembly Frame
The NIM Bin Assembly frame (GA-ESI P/N 04030801-001) is an all metal structural support for the
RM-1000 module, the I-F Converter Module, and 24 volts DC power supply and, therefore,
requires seismic qualification. The NIM Bin Assembly frame is similar to the tested NIM Bin
Assembly Frame (GA-ESI P/N 04502001-001). The test article with the subassemblies installed
was tested seismically as reported in GA-ESI document 04508905-QR. The RM-1000 NIM Bin
Assembly was subjected and
Shutdown Earthquakes (SSE).
and The Test Response Spectra (TRS)
for a typical SSE in the X-Y plane are shown in Figures 3-4 and 3-5. The RM-1000 NIM Bin
Assembly and its mounting hardware successfully passed this testing. The assembly frame is
considered qualified.
3.3.1.2 RM-1000 Modules
The RM-1000 module (SE P/N 04501200-004) is similar to the RM-1000 modules tested (GA-ESI
P/N 04501000-001) and reported in GA-ESI document 04508905-OR and 04508905-1SP. GA-
ESI report 04508905-1SP provides a similarity analysis. The RM-1000 modules limited life
components were age conditioned prior to performing these tests.
Following the environmental qualification test, the RM-1000 Module was given a seismic
qualification test as reported in GA-ESI document 04508905-QR. A pre-seismic functional test was
performed on RM-1 000 module.
04038903-7SP
RevC Page 19
25402-011 -VI A-HARA-001 90-001
The modules passed the functional test.
The RM-1000 modules were placed in a power up and test condition. Selected closed contacts of
the alarm relays were monitored for chatter throughout the tests. A current and voltage analog
output from each module was monitored throughout the test.
The modules were subjected to as described in Section
3.3.1.1. The typical TRSs are shown in Figures 3-4 and 3-5. The relays did not chatter and there
was no loss of analog signal throughout the testing.
Following the seismic testing the modules were given a post-seismic functional test. The RM-1000
modules passed the test and are considered seismically qualified.
3.3.1.3 I-F Converter Modules
The I-F Converter Module (GA-ESI P/N 04501351-001) is similar to the tested I-F Converter
(GA-ESI P/N 04506150-001) and reported in GA-ESI document 04508905-QR. The similarity
analysis for the I-F Converter Module is provided in GA-ESI report 04508905-2SP.
Following the environmental qualification test, the I-F Converter Module was given a seismic
qualification test as reported in GA-ESI document 04508905-QR. A pre-seismic functional test was
performed.
The modules passed the functional test.
~04038903-7SP
Rev C Page 20
25402-011 -VI A-HARA-001 90-001
The I-F Converter Module was subjected to the same seismic testing as the RM-1000 Modules.
The I-F Converter Module remained functional during those tests. The TRS versus RRS curves
for the tests are shown in Figures 3-4 and 3-5. The module passed a post seismic functional
test and is considered qualified. The figures show that the TRS fully enveloped the RRS (CEB-
SS-5.10 Rev. 3, Figure 3-1) shown in Figure 3-3.

3.3.1.4 Power Supply Bracket
The Power Supply Bracket (GA-ESI P/N 04502017-001 and -002) and its bolt mounting are
analyzed in Appendix A using the calculated weight and analyzed at in all directions.
The analyses show that the stress levels of the bracket assembly are within the allowable
stresses for both the GA-ESI generic and TVA specific cases. The power supply bracket is
considered seismically adequate and qualified.
3.3.1.5 Power Supply
The 24 Volt Power Supply (GA-ESI P/N 04502050-001) is attached to the bracket qualified in
3.3.1.4 and to the back of the NIM Bin Assembly and provides power to the RM-1000 and I-F
Converter Modules. The power supply is a replacement power supply for the originally tested
power supply (GA-ESI P/N 04502005-001). GA-ESI document 04508905-QR demonstrates
that the replacement power supply is similar to the test article, since they are by the same
manufacturer and model series. The replacement power supply has a higher current rating and,
therefore, slightly heavier. The Technical Evaluation further demonstrates that the slightly
greater weight does not affect the seismic qualification.
The original power supply (test article) parts that had age related failure mechanisms (aluminum
electrolytic capacitors, transformer, coils, and wire) were age conditioned as described in GA-
ESI document 04508905-QR. The age conditioned parts were then assembled into the two
power supplies that were mounted on the rear of the NIM Bin Assembly Frame and provided
power to the RM-1000 processor modules being qualified. Sections 3.3.1.1, 3.3.1.2, and 3.3.1.3
described the tests performed. The low voltage power supply is considered seismically
qualified.
3.3.2 Line Filter
The separately provided line filter is qualified by analysis described in GA-ESI document
04438901-QSR, Appendix A7. The line filter is an
It is consider rigid and, Pereore, LP1aceleraion levels pusmargin are used for the analysis. The accelerations used ar in all three axes. These
are much greater than the accelerations required to meet - rol Room panel seismic
requirements (Figure 3-3). The maximum principal stresses in the fasteners are
__ These are well within the TVA stress allowable.

3.3.3 RD-23 Detector
The RD-23 Detector (GA-ESI P/N 03602062-001) is the same detector as the tested RD-23
Detector reported in GA-ESI report E-254-0960. The seismic tests were Mwith the test
article attached rigidly to the shake table in the same configuration as the unit being qualified
would be in the field. There wasn't any amplification between the shake table and the mounting
location. An RP-2C Module was connected to the RD-23 detector throughout the testing and a
= output from the detector was used during the testing to verify
operation. The test article was given 0 Operating Basis Earthquake (OBE) tests and 0
Safe Shutdown Earthquake (SSE) test then rotated f and the test sequence repeated.
Figures 3-6 and 3-7 shows the accelerometer response at the detector and compares the fSTest Response Spectra (TRS) to the Required Response Spectra (RRS). The test
article remained intact and functional throughout the testing and is considered qualified. The
detector passed a post seismic functional test and is considered qualified.

6 SOFTWARE QUALIFICATION BASISThe RM-1000 software has been thoroughly Verified & Validated to the latest standards
available in 1998. Version 1.2 was approved for use in similar monitors delivered to Browns
Ferry Plant, based on TVA Specification SS-E18.15.01, Rev. 3.
Software Qualification for the TVA Replacement Radiation Monitors is based on the
requirements described in GA-ESI document 04038903-QSR section 3.5 for software
developed under a 10 CFR 50 Appendix B program. The qualification demonstrates that the
software V&V program meets the intent of RG1.152-2005 by describing the requested
information in TVA specification SS-E18.15.01, Rev. 3 section 5.2.
GA-ESI's software qualification program is in accordance with 10CFR 50 Appendix B. Formal
configuration control and error reporting fully meet the requirements of 10CFR50 Appendix B as
well as 10CFR Part 21.

A.3 EQUIPMENT DESCRIPTION
Table A-1 lists the analysis performed and its associated subsection for the power supply
assembly. The worst case condition is the stress on the four screws attaching the power supply
assembly to the back of the RM-1000 NIM Bin module. The natural frequency of the power
supply bracket is calculated as well as the highest stress bracket cross section. The four
screws attaching the terminal block/fuse assembly to the bracket have much less stress than
the four screws being analyzed. They are the same size and hold much less weight. Figure A-
1 shows the power supply assembly and identifies the locations being analyzed.

A.4 METHOD
GA-ESI's seismic analyses use the following conservative approach. The natural frequency of the
component being analyzed is determined, if feasible. Components in the rigid range (natural
frequencies greater than 33 hertz) use the Zero Period Acceleration (ZPA) times to provide
margin. If the natural frequency of the component being analyzed cannot be determined, the peak
acceleration found for the appropriate damping level on the RRS (ARS), plus any amplification,
multiplied by 0 is used. The result, of the method used, is the acceleration of the mass
concentrated at its center of gravity.
Power Supply Assembly is attached to the back of the NIM Bin module installed in the Control
Room panel which has high g low frequency accelerations in all directions. Therefore, the seismic
analysis uses the maximum acceleration shown in Figure 3-3 of = from • with a
multiplication factor of N for multimodal considerations.

Seismic forces (plus weight) are independently applied to the center of mass in the three
orthogonal axes that produce the highest stress in the part. The tensile and shear stresses are
calculated for each reaction. Stresses of the same type are combined using either the root of the
sum of their squares or their sum, if acting in the same direction. The maximum shear and tensile
stresses are then calculated and compared to the material allowable stresses.
In cases where a single RRS (ARS) is specified for the horizontal axis, the acceleration may be
taken as the maximum acceleration acting in one direction. The components can be analyzed for
the maximum acceleration acting separately in the x axis, the z axis, and at a 45 degree angle with
the x and z axis.
The analyses are performed using Microsoft Excel.
A.5 ACCEPTANCE CRITERIA
A.5.1 GA-ESI ACCEPTANCE CRITERIA
GA-ESI has established acceptance criteria for generic analysis of structural elements of radiation
monitoring system in order to use the analysis for most customer seismic conditions. These criteria
are conservative using generic RRS curves established for generic qualification testing. GA-ESI's
RRS are based on • and the accelerations used are given in Table A-2.

GA-ESI uses the following conservative allowable stress relationships.
1. Total maximum allowable principal tensile stress is M times the yield strength of the
material.
2. Total maximum allowable principal shear stress is M imes the yield strength of the
material.
A.5.2 ALLOWABLE BOLT STRESS CALCULATIONS
The allowable stresses for ductile materials for non-pressure boundary members, welds, and
threaded fasteners are given by GA-ESI document 04038903-QSR:
a. Pure Shear:
b. Pure Tension
Where Su = minimum ultimate tensile strength

A.6 CONCLUSIONS
The analyses, of the equipment listed in Table A-i, demonstrate that the equipment's design is
adequate and meets the acceptance criteria for both GA-ESI Generic and TVA Control Room
applications.
