3.1.1.S Pressurizer Whenever the reactor is at hot shutdown or critical the pressurizer shall have at least 100 kw of heaters operable and a water level maintained between 12K and 875 of level span.

If the pressurizer is inoperable due to heaters or )vater level, restore the pressurizer to operable status within 6 hrs

. or have the RHR system in operation within an additional 6 hrs.

Bases:

The plant is designed to operate with all reactor coolant loops in operation and maintain the DNBR above 1.30 during all normal

operations and anticipated transients.

Heat transfer analyses show that reactor heat equivalent to 130 MWT (8.5%) can be removed by natural circulation alone.

Therefore operation with one operating reactor coolant loop while below 130 MWT provides adequate margin.

The specification permits an orderly reduction in power if a reactor coolant pump is lost during operation between 130 MWT and 50% of rated power.

Above 50% power, an automatic reactor trip will occur if either pump is lost.

The power-to-flow ratio will be maintained equal to or less than one which ensures that the minimum DNB ratio increases at lower flow since the maximum enthalpy rise does not increase.

When the reactor coolant system average temperature is above 350'F, a single reactor coolant loop provides sufficient heat removal capability for removing decay heat;

however, single failure considerations require one loop be in operation and the other loop be capable of removing heat via natural circulation.

When the re'actor coolant system average temperature is between 200'F and 3SO'F or while in cold shutdown, a single reactor coolant loop or RHR 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 specification requires two RHR loops to be operable.

When the boron concentration of the reactor coolant system is to r'e reduced the process must be uniform.to prevent sudden reactivity 3.1 4c Amendment No.

changes in the reactor.

Mixing of the reactor coolant will be sufficient to prevent a sudden increase in reactivity if at least one reactor coolant pump or one residual heat, removal pump is running while the change is taking place.

The residual heat removal pump will circulate the primary system volume in approximately one half hour.

The pressurizer is of no concern because of the low pressurizer volume and because the pressurizer boron concentration will be higher than that of the rest of the reactor coolant.

Nhen the boron concentration of the reactor coolant system is to be increased, the process must be uniform to prevent sudden reactivity increases in the reactor during subsequent startup of the reactor coolant pumps.

Mixing of the reactor coolant will be sufficient to maintain a uniform boron concentration if at least one reactor coolant pump is running while the change is taking place.

Emergency boration without a reactor coolant pump in operation is not prohibited by this specification.

Prohibiting reactor coolant pump starts without a large void in the pressurizer or without a limited RCS temperature differential will prevent RCS overpressurization due to'xpansion of cooler RCS water as it enters a warmer steam generator.

A 38% level in the pressurizer will accommodate the swell resulting from a reactor coolant pump start with a RCS temperature of 140'F and steam generator secondary side temperature of 340'F, or the maximum temperature which usually exists prior to cooling the reactor with the"RHR system.

3.1-4d Amendment No.

<3

Temperature requirements for the steam generator correspond with C

measured NDT for the shell and allowable thermal stresses in the tube sheet.

.Each of the pressurizer code safety valves is designed to relieve 288,000 lbs. per hr. of saturated steam at the valve set point.

Below 3SO'P and 350 psig in the reactor coolant system, the residual heat removal system can remove decay heat and thereby control system temperature and pressure.

If no residual heat were removed by any of the means available the amount of steam which could be generated at. safety valve relief pressure would be less than half the valves'apacity.

One valve therefore provides adequate defense against overpressurization.

The power operated relief valves (PORVs) operate to relieve RCS pressure below the setting of the pressurizer code safety valves.

These relief valves have remotely operated block valves to pro-vide a positive shutoff capability should a relief valve become inoperable.

The electrical power for both the relief valves and the block valves is capab'Ie of being supplied from an emergency power source to ensure the ability to seal this possible RCS leakage path.

The requirement that 100 kw of pressurizer heaters and their associated controls be capable of being supplied electrical power from an emer gency bus provides assurance that these heaters can be energized during a loss of offsite power condition to maintain natural circulation at hot shutdown and during cooldown.(
