PRESSURE-TEMPERATURE LIMITS The Reactor Coolant System (except for the pressurizer) pressure and temperature shall be limited during heatup, cooldown, criticality (except for lower power physics tests),
and inservice leak and hydrostatic testing in accordance with the limit lines shown on Figures 3.1-1a through 3.l-ld (Unit 3) and 3.1-la, 3.1-1b, 3.1-2c and 3.1-2d (Unit 0).
Allowable pressure-temperature combinations are BELOW AND TO THE RIGHT of the lines on the Figures.
Heatup and cooldown rate limits are:
a.
A maximum heatup rate of 100oF in any one hour.
b.
A maximum cooldown rate of 100oF in any one hour.
c.
A maximum temperature change of > 5oF in any one hour during hydrostatic testing operation above system design pressure.
The pressurizer pressure and temperature shall be limited in accordance with the following:
d.
The pressurizer shall be limited tq a maximum heatup rate of 100oF in any one hour, and a maximum cooldown rate of 200oF in any one hour.
e.
The pressurizer shall be limited to a maximum Reactor Coolant System spray water temperature differential of 320oF.
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 within 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 />.
