{ DISCUSSION OF PROPOSED TECMICAL SPECIFICATION CHANGES North Anna Units 1 and 2 Technical Specifications, Tables 3.6-1, provide a I list of containment isolation valves These valves ensure that the containment atmosphere will be isolated from the outside environment in the l event of a release of radioactive material to the containment atmosphere or pressurization of the containment. The current list in the Unit 1 and 2 Tables 3.6-1 contains errors and omissions. The following add / delete changes are made to obtain consistency between the Unit 1 and 2 Tables 3.6-1, to identify the fire protection isolatica valves, and to delete a valve listed in error. Manual valve 1-SI-77, High Head Safety Injection (Boron Injection Tank Bypass) is added to the Unit 1 Table 3.6-1 and corresponds to valve 2-SI-83 listed in the Unit 2 Table 3.6-1. Check valves 1-RS-123 and 1-RS-138, Casing Cooling to Outside Recirculation Spray Pump, are added to the Unit 1 Table 3.6-1 and correspond to valves 2-RS-103 and 2-RS-118 in the Unit 2 Table 3.6-1. Phase "B" isolation valve TV-IA-102A, Instrument Air to Reactor Containment, is added to the Unit 1 Table 3.6-1 and corresponds to valve TV-IA-202A in the Unit 2 Table 3.6-1. The # symbol is added to TV-RM1000, Air Radiation Monitor Return, and to TV-SV102-1, Condenser Air Ejector Veat, in Unit 1 Table 3.6-1 to correspond to TV-RH200D and TV-SV202-1 in the Unit 2 Table 3.6-1. Manual valves 2-WT-354, 2-WT-357, and 2-WT-351, Chemical Feed Lines, are added to the Unit 2 Table 3.6-1 with the symbols # and

  • and correspond to valves 1-WT-354, 1-WT-357 and 1-WT-351 in the Unit 1 Table 3.6-1.

Manual valve 1-FP-275, Fire Protection Hose Standpipe, is added to the Unit 1 Table 3.6-1, and check valve 2-FP-79, Fire Protection Supply, and manual valves 2-FP-81 and 2-FP-82, Fire Protection Supply, are added to the Unit 2 Table 3.6-1 to identify fire protection isolation valves not previously specified. The # symbol is added to 1-FP-275 and 2-FP-82 because these valves are the second isolation valves outside containment and are not required to be Type C tested. The # symbol is removed from check valve 1-FP-272 in Unit 1 Table 3.6-1. This valve is the isolation valve inside containment and will be Type C tested. Check valve 1-SI-85 in the Unit 1 Table 3.6-1 was listed in error and has been deleted. The correct check valve for high head safety injection to the RCS (except for the boron injection line), 1-SI-185, is already included in the Unit 1 Table 3.6-1. Each of these changes to the Unit 1 and 2 Tables 3.6-1 have been evaluated with respect to current Type C testinrg procedures and where any valve tests have been omitted, station deviations have been submitted. The following valves have been determined to be either exempt from the Type C testing penalty for the Type A test results or exempt from Type C testing. The identification of these containment isolation valves is based on the analysis of those penetrations that are maintained in a water-filled configuration during accident conditions, or are part of a closed system in containment. As permitted by III.A.l.(d) of 10 CFR 50 Appendix J, those penetrations that are water filled are not required to be vented and drained during the Type A test, however, these valves will continue to be Type C tested. The valves associated with a closed system in containment which does not rupture as a result of a loss of coolant accident are not required to be Type C tested. An evaluation of these penetrations as suggested by the enclosure to NRC letter " Request for Additional Information to Complete the Evaluation of Water Sealed Penetrations," dated August 11, 1988, (similar data requested for the removal of certain water-filled penetrations at Surry Power Station) is included in Attachment 4

The isolation valves associated with water-filled penetrations are not potential containment atmosphere leak paths. These valves will continue to be Type C tested to demonstrate leakage rates do not exceed the allowable. The leakage, however, will not be included in the Type A leakage rate. This approach was approved by NRC SER dated November 21, 1988 for similar water-filled penetrations for Surry Power Station. This test method will be denoted by addition of the symbol ## beside the valves.

In addition to being a closed system in containment, the Service Water valves receive an "open" signal on a Containment Depressurization Actuation. signal and are, therefore, water filled under accident conditions. l l

1 l BASIS FOR N3 SIGNIFICANT HAZARDS CONSIDERATION The proposed change does not involve a significant hazards consideration as defined in 10 CFR 50.92 because the revision to Unit 1 and 2 Tables 3.6-1 ? would not: 1) Involve a significant increase in the probability or consequences of an accident previously evaluated. The proposed change does not change the design or operation of any system and equipment. Leakage testing continues to be performed in accordance with 10 CFR 50 Apr9ndix J to ensure containment isolation in the event of a release of radioactive material to containment atmosphere or pressurization of the containment. The proposed change updates Tables 3.6-1 and reflects the requirements of Appendix J. 2) Create the possibility of a new or different kind of accident from any accident previously evaluated. The isolation valves associated with water-filled penetrations will continue to be Type C tested and their. leakage' rates will continue to be added to the local leakage rate. The isolation valves associated with closed systems.which will not be Type C tested meet the requirements of 10 CFR 50 Appendix J for exemption. 3) Involve a' significant reduction in the margin of safety. The l proposed change meets the requirements of 10 CFR 50 Appendix J to. ensure containment isolation. I

SUMMARY

NORTH ANNA UNITS 1 AND 2 Virginia Electric and Power Company

o r I w NORTH ANNA UNITS 1 & 2 WATER-FILLED / CLOSED SYSTEM CONTAINMENT PENETRATIONS K" CONTAINMENT INTEGRATED LEAK RATE TEST EVALUATION

SUMMARY

) l The attached data sheets provide an evaluation of water-filled containment penetrations 7,15, 22, 46, 60, 61, 62, 66, 67,113, and 114, and of closed system containment penetrations 79, 80, 81, 82, 83, 84, 85, and 86 against the 4 criteria specified in the NRC Letter, " Request For Additional Information To { Complete The Evaluation Of Water Sealed Penetrations," dated August 11, 1988, j (which was issued by the NRC to obtain similar data for the removal of certain j water-filled penetrations at the Surry Power Station) and the applicable i requirements'of Standard Review Plan 6.2.4 for closed systems. In summary,- these data sheets indicate the following for the water-filled penetrations: 1) The penetrations. in-question are either portions' of safety-related systems which contain water supplied by pumps that are activated (if not already in-operation) at the time of accident initiation, or are portions of systems which contain water that is trapped in the . penetration at the time of accident initiation. 2) The Quality Group of the pumps' and associated piping between the water source and containment penetrations are as follows: Q1/Q2 - Penetration and Containment Isolation Valves. Q2/Q3 - Water Source to Containment Isolation Valves. 3) The portions of the systems in question are Seismic Class I (including the RWST) and are provided with missile protection in accordance with Tornado Criterion P (not applicable to the RWST). 4) The portions of the systems in question that are important to safety and are outside of ' containment are suitably protected from pipe whip, jet force, and bELB, and will operate properly in a LOCA transient. 5) The pumps and electrically operated valves have a Safety Class 1E power supply available. 6) The water sources are available and reliable.

a 7) A water pressure head is maintained at the penetration under single failure criteria. 8) Most containment isolation valves are either gate or globe valves. Gate valves do not have the stem or packing exposed to line pressure when closed, therefore the orientation of the valve in the line is immaterial. Globe valves are oriented sucii that the configuration prevents the containment atmosphere from passing through the packing of a closed valve inside containment to the outside atmosphere. 9) Water pressures maintained at the penetrations are higher than containment pressure.

10) Operator actions are not required for the initial accident mitigation configuration. Operator actions are required to establish later recirculation modes as provided by appropriate procedure.s, i.e., cold leg injection mode is the line up for the first 10 hours, with hot leg injection following.

Based on the above and the attached data sheets, it is concluded that the penetrations in question are appropriately water sealed under post-accident conditions and therefore may be excluded from the vent and drain requirements of the Type A tests and are not subject to Type C penalty requirements. In summary, for the closed system penetrations the data sheets indicate that these penetrations are part of closed systems in containment that: a) Do not communicate with either the reactor coolant system or the containment atmosphere. b) Are protected against missiles and pipe whip. c) Are designated seismic Category I. d) Are classified Safety Class 2. e) Are designed to withstand temperatures at least equal to the containment design temperature. f) Are designed to withstand the external pressure from the containment structure acceptance test. g) Are designed to withstand the LOCA transient and environment. Based on the above and the attached data sheets, it is concluded that the penetrations identified as closed system penetrations are part of systems in i containment that meet the criteria for closed systems of the Standard Review Plan 6.2.4 and are therefore not subject to rupture as a result of a loss of coolant accident. Accordingly, the associated isolation valves are not subject to Type C testing per Section III.A.1(d) of 10 CFR 50 Appendix J.

JUSTIFICATION FOR THE REQUESTED CHANGE The identification of penetrations as being exempt from being included in the Containment Integrated Leak Rate Test (CILRT) is based on those penetrations being maintained in a water-filled configuration during accident conditions, or that they are part of a closed system in containment. Section III.A.l.(d) of 10 CFR 50 Appendix J requires that: 1) Those portions of the fluid systems that are part of the reactor coolant pressure boundary and open directly to the containment atmosphere under post-accident conditions and become an extension of the boundary shall be opened or vented ta the containment atmosphere prior to and during the Type A test. 2) Portions of closed systems inside containment that penetrate containment and rupture as a result of a loss of coolant accident shall be vented to the containment atmosphere. 3) All vented systems shall be drained of water or other fluids to the extent necessary to assure exposure of the system containment isolation valves to containment air test pressure. l The exceptions to this criteria as permitted by this Section are that: a) Systems that are required to maintain the the plant in a safe condition during the test shall be operable in their normal mode, and need not be vented, j b) Systems that are normally filled with water and operating under post-accident conditions need not be vented. This latter exception forms the basis for the determination that water-filled penetrations are exempt from venting and draining and Type C penalties for the Type A test. The isolation valves will continue to be Type C tested to demonstrate leakage rates do not exceed allowable. The leakage will continue to be added to the local leakage rate, but will not be included in the Type A leakage rate. This approach was approved by NRC SER dated November 21, 1988 for similar penetrations for Surry Power Station. The basis for the determination that closed system penetrations are exempt from Type C testing comes from requirement 2 above which states that closed systems that penetrate containment and rupture as a result of a loss of coolant accident are required to be vented during the Type A test. The penetrations noted on the attached data sheets are part of closed systems that meet the criteria of the Standard Review Plan 6.2.4 and are therefore not subject to rupture as a result of LOCA. Accordingly, the isolation valves associated with these penetrations are considered to be exempt from Type C testing.
