.I The plant is designed to operate with both reactor coolant loops and

during all normal operations and anticipated transients.
A single reactor coolant' loop with its steam generator filled above the
, low level trip setpoint provides sufficient heat removal capability for core cooling while in MODES 2 and 3; however, single failure considerations require plant shutdown if component repairs and/or corrective actions cannot be made within the allowable out-of-service time.
1 In MODES 4 and 5, a single reactor coolant loop or shutdown cooling loop provides sufficient heat removal capability for removing decay heat; but single
" failure considerations require that at least two loops be OPERABLE.
Thus, if the reactor coolant loops are not OPERABLE, this speci fication requires two shutdown cooling loops to be OPERABLE.
The operation of one Ocactor Coolant Pump or one shutdown cooling pump provides adequate flow to ensure mixing, prevent stratification ard produce gradual reactivity changes during boron concentration reductions in the Reactor Coolant System.
The reactivity change rate associated with boron reductions will, therefore, be within the capability of operator recognition and control.
O The restrictions on sterting a aeector Cecient Pump during 800e5 4 end 5 with one or more RCS cold legs < 275 F are provided to prevent RCS pressure transients, caused by enargy additions from the secondary system, which could exceed the limits-of Appendix G to 10 CFR Part 50.
The RCS will be protected against overpressure transients and will not exceed the limits of Appendix G by either (1) restricting the water volume in the pressurizer ano thereby providing a volume for the primary coolant to expand into or (2) by restrict-ing starting of the RC's to wheg the gecondary water temperature of each steam generator is less than 46 F (34 F when measured by a surface contact l

3/4.4 REACTOR COOLANT SYSTEM BASES 3/4.4.1 COOLANT LOOPS AND COOLANT CIRCULATION t
The plant.is designed to operate with both reactor calant loops and associated reactor coolant pumps in operation, and maintain DNBR above 1.195 during all normal-operations and anticipated transients.;
A single reactor coolant loop with its steam generator filled above the low level trip setpoint provides sufficient heat removal capability for core cooling while in MODES 2 and 3; however, single failure considerations require plant shutdown if component repairs and/or corrective actions cannot be made within the allowable out-of-service time.
l In MODES 4 and 5, a single reactor coolant loop or shutdown cooling loop provides sufficient heat removal capability for removing decay ' heat; but single fail are consideraticas require that at least two loops be OPERABLE. Thus, if the reactor coolant loops are not OPERABLE, this specification requires two shutdown cooling loops to be OPERABLE.
The operation of one Reactor Coolant Pump or one shutdown cooling pump provides adequate flow to ensure mixing, preventing stratification and produce gradual reactivity changes during boron concentration reductions in the Reactor Coolant System. The reactivity change rate associated with boron reductions will, therefore, be within the capability of operator recognition and control.
The restrictions on starting a Reactor Coolant Pump during MODES 4 and 5 with one or more RCS cold ~ legs $ 275 F are provided to prevent RCS pressure transients, caused by energy additions from the secondary system, which could exceed the limits of Appendix G to 10 CFR Part 50.'
The RCS will be protected against overpressure transients and will not exceed the limits of Appendix G by either (1) restricting the water volume for the primary coolant to expand into or (2) by restricting starting of the RCPs to when the secondary water temperature of each steam generator is less than 46 F (34 F when measured by a surface contact instrument) above the coolant temperature la the reactor vessel.
3/4.4.2 SAFETY VALVES The pressurizer code safety valves operate to prevent the RCS from being pressurized above its pafety Limt of 2750 psia. Each safety valve is designe.d to relieve approximately 3 x 10 lbs per hour of saturated steam at the valve setpoint. The relief l
capacity of a single safety valve is adequate to relieve any overpressure condition which could occur during shutdown. In the event that no safety valves are OPERABLE, an operating shutdown cooling loop, connected to the RCS, provides overpressure relief
- capability and will prevent RCS overpressurization.
During operation, all pressurizer code safety valves must be OPERABLE to prevent the RCS from being pressurized above its safety limit of 2750 psia.
