57. Exercising this valve requires isolating instrument air to the containment thereby failing numerous air operated valves. Al-though control of these valves is not required during an accident, it is required for nomal reactor operation. Therefore the valve is full stroke exercised in Mode 5 at 3 nonth intervals as allowed by Section XI Article IUV-3520.

53. Valve cannot be stroked during plant operation without securing charging and letdown. As this would unnecessarily hazard plant reliability the valve is full stroke exercised in Mode 5 at 3 nonth intervals as allowed by Section XI Article IWV-3410,

59. Valve is tested at 18 month intervals. The test includes a channel calibration of the actuation channel. A channel functional test, excluding valve operation, is performed within 31 days prior to entering a condition when this valve is required to serve as an MPT relief, and every 31 days thereafter when valve is required to be operable.

60. Valve opens on a safety injection actuation signal and/or under-voltage on 4KV emergency bus.

61. Valve is required to prevent draining safety injection tank when the reactor coolant system is depressurized for maintenance. Valve is locked open and power is removed from valve operator during operation. Valve position before and after operation is logged.

Section XI Article IWV-3700 requires no regular testing for such valves.

62. Valve cannot be stroked during plant operation without requiring operators to enter a high radiation area within the containment.

fian ren exposure if the valve was stroked during operation would be 250 nren gamma and 500 nrem neutron. Therefore the valve is full stroke tested in itode 5 at 3 month intervals as allowed by Section XI Article IWV-3410. One hour per valve.

63. Valve cannot be stroked during plant operation without stopping RCP seal bleed off flow reducing RCP seal realiability. Valve is full stroke tested on Mode 5 at 3 nonth intervals as allowed by Section XI Article IWV-3410.

64. Valve cannot be stroked during operation without inducing a pressure transient on the reactor coolant system which would reduce plant reliability. Valve is full stroke exercised in Mode 5 at 3 month intervals as allowed by Section XI Article IUV-3410.

65. Exercising this valve during operation requires that one salt water header be placed out of service which would sinultaneously place one service water header and conponent cooling heat exchanger out of service, thus placing 2 containment coolers,1 diesel generator and 1 ECCS punp room air cooler out of service and reducing the reliability of one HPSI pump, one LPSI punp, and all reactor coolant pumps. Therefore valve is full stroke exercised in Mode 5 at 3 month intervals as allowed by.Section XI Article IWV-3410.
