PRIMARY COOLANT SYSTEM I PRIMARY COOLANT GAS VENT SYSTEM I LIMITING CONDITION FOR OPERATION I 3 .1. 9 The following primary coolant system vent paths consisting of I at least two valves in series shall be operable and closed. I I

a. Reactor Vessel vent path to containment and reactor vessel I vent path to quench tank. I I

b. Pressurizer vent path to containment and pressurizer vent path I to quench tank. I I

APPLICABILITY: Power Operation, Hot Standby, and Hot Shutdown I I

ACTION: I

'

I

a. With either primary coolant gas vent valve PRV-1071 or PRV-1072 I inoperable, startup activities and power operation may continue I provided the inoperable vent valve is electrically locked closed, I and with the key removed, restore the inoperable valve to I operable status status within 30 days, or, be in hot shutdown I within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in cold shutdown within the following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />.

b. With both reactor vessel vent paths or both pressurizer vent I paths inoperable (PRV-1067 and 1068, o_r PRV-1069 and 1070, or I PRV-1071 and 1072), maintain the inoperable vent paths I electrically locked closed and with the keys removed for the I inoperable valves and restore at least one of the inoperab_le I vent paths to operable status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />, or be in hot I shutdown within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in cold shutdown within the I following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />. I I

BASIS I I

The primary coolant gas vent system (PCGVS) is designed to reliev'e I steam or noncondensible gases from the primary system that could I inhibit natural circulation core cooling. Vent paths from both the I reactor head and p-ressurizer connect to a common header which then I divides into two flow paths, either directly to the containment I through PRV-1071, or to the quench tank through PRV-1072, which may I relieve through its rupture disk to containment depending on the I volume of gas being discharged. Restricting orifices on both the I reactor vessel and pressurizer vent lines limit mass loss to less I than the makeup capacity of a single charging pump. I I

Minimum Frequencies for Equipment Tests

12. Iodine Removal System The Iodine Removal System shall be demonstrated operable:

a. At least once per 31 days by verifying that each valve (manual, power operated or automatic) in the flow path that is not locked, sealed or otherwise secured in position, is in its correct position.

b. At least once per 6 months by:

1. Verifying that tanks T-102 and T-103 contain the minimum required volumes.

2. Verifying the concentration of hydrazine in T-102 and sodium hydroxide in T-103.

c. At least once per refueling cycle, during shutdown, by verifying that each automatic valve in the flow path actuates to its correct position.

13. Containment Purge and Ventilation Isolation Valves The containment Purge and Ventilation isolation Valves shall be determined closed:

a. At least once per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> by checking the valve position indicator in the control room.

b. At least once every 6 months by performing a leak rate test between valves.

14. Primary Coolant Gas Vent System I I

Each primary coolant gas vent path from the reactor vessel and I pressurizer shall be demonstrated operable at least once each I refueling cycle by: I I

1. Verifying all manual isolation valves in each vent path' I are locked in the open position. I I

2. Cycling each valve in the vent path.through at least one I complete cycle of ftill travel from the control room I during cold shutdown or refueling. I I

3. Verifying flow through the reactor coolant vent system I vent paths during cold shutdown or refueling. I 4-15b Amendment Sl, 90, TSP0488-0101-NL04
