NOTE 1 All vented systems shall be drained of water or other fluids to the extent necessary to assure exposure of the system 7 l -

containment isolation valves to containment atmosphere and to assure they will be subjected to the test differential -  ;

pressure.

NOTE 2 Fluid system that is r :t of the reactor coolant pressure boundary or open directly to the containment atmosphere under post-accident conditons (vented to containment atmosphere during Type A test).  !

NOTE 3 Closed system inside containment that penetrates containment and postulated to rupture as a result of a loss of coolant ,

accident (vented to containment atmosphere during Type A test).  ;

i i NOTE 4 System required to maintain the plant in a safe condition during the test (need not be vented). j NOTE 5 System normally filled with water or under pressure and operating under post-accident condition (need not be vented). i

NOTE 6 a. Containment penetration whose design incorporates resilient seals, gaskets, or sealant compounds, piping penetration filled with expansion bellows, and electrical penetrations fitted with flexible metal seal assemblies.
b. Air lock door seals including door operating mechanisms which are part of the containment pressure boundary. ,

l c. Doors with resilient seals or gaskets except for seal welded doors.

d. Components other than those above which must meet the acceptance criteria of Type B tests.

NOTE 7 a. Isolation valves provide a direct connection between the inside and outside atmospheres of the primary reactor i containment under normal operation, such as purge and ventilation, vacuum relief, and instrument valves.

b. Isolation valves are required to close automatically upon receipt of a containment isolation signal in response to controls intended to affect containment isolation.

TABLE 16.6-1 (NOTES) ,-

c. Isolation valves are required to operate intermittently under post accident conditions.
d. Check valve (s) used for containment isolation.

NOTE 8 DELETED NOTE 9 Reverse direction test ofinside containment isolation valve authorized. Leakage results are conservative.

NOTE 10 System is submerged during post-accident conditions and performance of Type A test. System will be drained to the extent possible. ,

NOTE 11 Type B test performed on the blind flanges inside the Reactor Building. Valves outside the containment are not tested.

NOTE 12 A one-time extension from the local leak test and corresponding exemption from Section III.D.2 and III.D.3 of Appendix J to 10 CFR Part 50 is granted such that it be performed during the 1983 Unit I refueling outage, provided that such outage begins nc later than July 16,1983.

NOTE 13 The requirements to perform a Type A test in accordance with Notes 1 and 3 of Table 4.4-1, will commence during the end ofcycle 12 refueling outage on Unit 1, and during the end of cycle 1I refueling outages on Units 2 and 3. For the Type C test, the initial test will be performed on Unit I during the end ofcycle 12 refueling outage, on Unit 2 no later than January 15,1990, and during the end ofcycle 11 refueling outage, on Unit 3. On Units 2 and 3, until Type C testing is performed, these penetrations may be utilized provided that compensatory measures described in W. H.

Owen's September 29,1989 letter and H. B. Tucker's October 4,1989 letter are implemented.
