4.6.3.3 At least once per 18 mo~th, verify that on a main steam isolation test signal, each main steam isolation valve specified in Table 3.6-1 actuates to its-isolation posi~ion.

• 4.6.3.4 The isolation time of each power operated or automatic valve of Table 3.6-1 shall be determined to be within its limit when tested pursuant to

, Specification 4.0.5.

4.6.3.5 Each containment purge isolation valve shall be demonstrated OPERABLE within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> after each closing of the valve, except. when the valve is being used for multiple cyclings, then at least once per 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />, by verifying that when the measured leakage rate is added to the leakage rates determined pursuant to Specification 4.6.l.2d. for all other Type B and C penetrations, the combined leakage rate is less than or equal to 0.60La.

~~:** lVCl, 1V0 CATEGORY: A c CLASS: 2 FUNCTION: Containment Isolation for Containment Purqe.

TEST REQUIREMENTS: Leak Rate Testinq less than each 24 months1 Stroke Time Measurement each three months; Fail Safe Testing each three months.

BASIS FOR RELIEF: a) Valves are passive durinq PoWer Operation. These valves cannot be opened during Power Operation per commitment to NRC in LER 50-272/79-55/0lT.

b) Because the safety-related function of these valves is containment isolation, they will be leak tested in accordance with Technical Specifications a.nd lOCFRSO, Appendix J. Thi.a test meets the intent of the ASME B&PV Code,Section XI for cateqory A valves used for containment isolation.

ALTERNATE TESTING: a) valves will be stroke timed and exercised at Cold Shutdown and Refuelinq.

b) Leak Rate Test per Technical Specification 4.6.l.2.d.

CATEGORY: A

~S: 2 FUNCTION: Containment Isolation (inside containment) for Containment Purge.

TEST REQUIREMENTS: Leak Rate Testing*less than 24 months1 Stroke Time Measurement each three months; Fail*safe Testing each three months.

BASIS FOR RELIEF: a) These valves are passive during Power Operation. They cannot be o~ed per commitment to NRC in LER 50-272/79-55/0lT.

b) Due to the physical arrangement of these valves, a test in the direction of accident flow is not possible. Also, because the safety-related function of these valves is containment isolation, they will be leak tested in accordance with Technical Specifications and lOCFRSO, Appendix J.

This test meets the intent of the ASME Code,Section XI for category A valves used for containment isolation *

.ALTERNATE TESTING: a) Valves will be stroke timed and exercised during Cold Shutdown and Refueling.

b) They will be tested in the opposite direction of flow when the lVCl and 1VC4 are tested in accordance with Technical Specification 4.6.1.2.d.

FUNCTION: COntaimnent Isolation (inside containment) for Containment Pressure/Vacuum Relief.

TEST REQUIREMENTS: Leak Rate Testing less than 24 months.

BASJ:S FOR RELIEF-: Due to the physica1 arrangement of this valve, a test in the direction of accident flow is not possible. A1so, because the safety-related function of this valve is containment iso1ation, it will be leak tested in accordance with Technical Specifications and lOCFR.50, Appendix J. This test meets the intent of the ASME Bi.PV Code, Section n for category A valves used for con-tainment isolation.

ALTERNATE TESTJ:NG: The valve will be*tested in the opposite direction of flow when the lVCS is tested in accordance with Technical Specification 4.6.1.2.d.

VALVE: 1VC7, lVCS, lVCll and 1VC12 CATEGORY: A CLASS: 2 FUNCTION: containment Isolation for containment Atmospheric Sampling.

TEST REQUIREMENTS: Leak Rate Testing less than each 24 months.

BASIS FOR RELIEF: Because the safety-related function of these valves is containment isolation, they will be leak tested in accordance with Technical Specifications and lOCFRSO, Appendix J. This test meets the intent of the ASME B&PV Code, Section XJ: for category A valves used for containment isolation.
