5.6.2.10 OTSG Tube Surveillance Program (continued)

4. Acceptance criteria:

a. Vocabulary as used in this Specification:

1. Tubing or Tube means that portion of the tube orsleeve which forms the primary system to secondarysystem pressure boundary.

2. Imperfection means an exception to the dimensions,finish or contour of a tube from that required byfabrication drawings or specifications. Eddy-current testing indications with signal to noiseratio > 5:1 and < 20% of the nominal tube wallthickness, if detectable, may be considered asimperfections. Indications with signal to noiseratio s 5:1 and voltage amplitude 12 volts willalso be considered imperfections.

3. Degradation means a service-induced cracking,wastage, wear, or general corrosion occurring oneither inside or outside of a-tube.

4. Degraded Tube means a tube containingimperfections 2 20% of the nominal wall thicknessif signal to noise ratio > 5:1 or indications withsignal to noise ratio 15:1, voltage amplitude > 2volts, with axial extent of < 0.25 inch, andcircumferential extent of < 120; caused bydegradation except where all such degradation hasbeen spanned by the installation of a sleeve.

5. % Degradation means the percentage of the tubewall thickness affected or removed by degradation.

6. Defect means an imperfection of such severity thatit exceeds the repair limit except where the I

imperfection has been spanned by the-installationof a sleeve. A tube containing a defect in itspressure boundary is defective. Any tube whichdoes not permit the passage of the eddy-currentinspection probe shall be deemed a defective tube.

7. Repair Limit means the imperfection at or beyondwhich the tube shall be restored to serviceabilityby the installation of a sleeve or removed fromservice because it may become unserviceable priorto the next inspection. The repair limit for eddycurrent indications with signal to noise ratios >5:1 is equal to 40% of the nominal tube wallthickness. 'The repair limit for eddy currentindications with signal to noise ratios s 5:1 is abobbin coil signal amplitude of > 2 volts, andaxial extent > 0.25 inches or circumferentialextent > 120 No more than five thousandsleeves my be installed in each OTSG.

8. Unserviceable describes the condition of a tube if *

it leaks or contains a defect large enough toaffect its structural integrity in the event of anOperating Basis Earthquake, a loss-of-coolantaccident, or a main steam line or feedwater linebreak, as specified in 5.6.2.10.3.c, above.

9. Tube Inspection means an inspection of the entireOTSG tube as far as possible.

b. The OTSG shall be determined OPERABLE after completingthe corresponding actions (plug or sleeve all tubesexceeding the plugging / sleeving limit and all tubescontaining through-wall cracks) required by Table5.6.2-2 (and Table 5.6.2-3 if the provisions ofSpecification 5.6.2.10.2.d are utilized). Defectivetubes may be repaired in accordance with the B&Wprocess (or method) equivalent to the method described I

5.6.2.12 Ventilation Filter Testing Program (VFTP)

A program shall be established to implement the following requiredtesting of the Control Room Emergency Ventilation System (CREVS)per the requirements specified in Regulatory Guide 1.52,Revision 2, 1978, and in accordance with ASME N510-1975 and ASMEN509-1976.

a. Demonstrate for each train of the CREVS that an inplace testof the high efficiency particulate air (HEPA) filters shows ;

a penetration and system bypass < 0.05% when tested in i

accordance with Regulatory Guide 1.52, Revision 2, 1978, and .

Iin accordance with ASME N510-1975 at a flowrate of 43,500cfm i 10%. j

b. Demonstrate for each train of the CREVS that an inplace testof the charcoal adsorber shows a penetration and systembypass < 0.05% when tested in accordance with RegulatoryGuide 1.52, Revision 2, and ASME N510-1989 at the systemflowrate of 43,500 cfm i 10L

5.6.2.13 Explosive Gas and Storage Tank Radioactivity Monitoring Program

This program provides controls for potentially explosive gasmixtures contained in the Radioactive Waste Disposal (WD) System,the quantity of radioactivity contained in gas storage tanks orfed into the offgas treatment system. The gaseous radioactivityquantities shall be determined following the methodology in BranchTechnical Position (BTP) ETSB 11-5, " Postulated RadioactiveRelease due to Waste Gas System Leak or Failure". The-liquidradwaste quantities shall be determined in accordance withStandard Review Plan, Section 15.7.3, " Postulated RadioactiveRelease due to Tank Failures".

The program shall include:

a. The limits for concentrations of hydrogen and oxygen in theRadioactive Waste Disposal (WD) System and a surveillanceprogram to ensure the limits are maintained. Such limitsshall be appropriate to the system's design criteria, (i.e.,whether or not the system is designed to withstand ahydrogen explosion),
