PRESSURE-TEMPERATURE LIMITS The Reactor Coolant System (except for the pressurizer) pressure and temperature shall be limited during heatup, cooldown, criticality (except for low power physics tests), . and inservice 'leak and hydrostatic testing in accordance with the limit lines shown on Figures 3.1-3.a through 3.1-1b. Allowable pressure-temperature combinations are 8ELOW AND TO THE RIGHT of the lines on the Figures. Heatup and cooldown rate 1imits are:

a. A maximum heatup rate of 100 F in any one hour.

. b. A maximum cooldown rate of 100 F in any one hour.

c. A maximum temperature change of > 5'F in any one hour during hydrostatic testing operation above system design pressure.

The pressurizer pressure and temperature shall be limited in accordance w'ith the following:

d. The pressurizer shall be limited to a maximum heatup rate of 100 F in any one hour. and a maximum cooldown rate of 200 F in any one hour.

e. 'he pressurizer shall be limited to a maximum Reactor Coolant System spray water temperature

~r differential of 320'F.

With any of the above limits exceeded, restore the temperature and/or pressure within the limits within 30.minutes; determine that the RCS or pressurizer remains acceptable for continued operations or, if at power. be in at least Hot Shutdown ~ithin the next, 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and 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 />.

tlith reactor power less than 70 percent Rated Thermal Power, the moderator temperature coefficient* shall not be rare positive than +5 x 10 ~ hK/K/oF.

Hhen this condition is not met, the reactor shall be made subcritical by an amount equal to or greater than the potential reactivity insertion due to depressurization and cooldown..

Mith reactor power greater than or equal to 70 percent Rated Thermal Power, the moderator temperature coeffi'eicient shall. not be more positive than 0 bK/K/ F. Hhen this condition is not met, the reactor shall be made subcritical by an amount equal to or greater than the potential reactivity insertion due to depressurization and cooldown.

• These moderator temperature coefficient conditions do not apply to low power physics tests.
