Amendment No.115 BEAVER VALLEY - UNIT 1 3/4 7-4

.j

~

REACTOR COOLANT SYSTEM BASES relieve any overpressure condition which could occur during l

shutdown.

In the event that no safety valves are OPERABLE, an I

operating RRR

loop, connected to the
RCS, provides overpressure relief capability and will prevent RCS overpressurization.

I During operation, all pressurizer code safety valves must be OPERABLE to prevent the RCS from being pressurized above its safety limit of 2735 psig.

The combined relief capacity of all of these j

valves is greater than the maximum surge rate resulting from a complete loss of load assuing no reactor trip until the first Reactor 4

Protective System trip set point is reached (i.e., no credit is taken for a

direct reactor trip on the loss of load) and also assuming no operation of the power operated relief valves or steam dump valves.

Demonstration of the safety valves lift settings will occur only during shutdown and will be performed in accordance with the provisions of Section XI of the ASME Boiler and Pressure Code.

3/4.4.4 PRESSURIZER The requiremen.t that (150)kw of pressurizer heaters and their cssociated controls be capable of being supplied electrical power from an emergency bus provides assurance that these heaters can be energized during a

loss of offsite power condition to maintain natural circulation at HOT STANDBY.

I 3/4.4.5 STEAM GENERATORS i

One OPERABLE steam generator in a non-isolated reactor coolant loop provides sufficient heat removal capability to remove decay heat after a

reactor shutdown.

The requirement for two O&ERABLE steam generators, combined with other requirements of the Limiting conditions for Operation ensures adequate decay heat removal capabilities for RCS temperatures greater than 350*F if one steam generator becomes inoperable due to single failure considerations.

Below 350*F, decay heat is removed by the RHR system.
