1.0 Pressure / Temperature Limits This Pressure-Temperature Limits Report for CR3 has been prepared in accordance with the requirements of Technical Specification Section 1.1.

The pressure / temperature (P/T) limits have been developed using the methodology provided in the references.

The following pressure-temperature limits are included in this report:

1) Allowable plant heatup and cooldown rates

2) Plant heatup P/T curve

3) Plant cooldown P/T curve

4) Plant inservice leak and hydrostatic testing P/T curve r

ALLOWABLE HEATUP AND COOLDOWN RATES -

a. A maximum heatup of 1000F in any one hour period,

b. For the temperature ranges specified below, the cooldown -

rates should be as specified below in any one hour period:

1. T > 270 0F - 1 100 F/Hr, ii. 0 150 F Hr, 270 F 2. T > 170 F iii. 170 F 2. T 1 10 0 Hr -

and,

c. - A maximum temperature change ofless than or equal to 5 F in any one hour period during h

~ above system design pressure. ydrostatic testing operation These limits are referred to by Technical Specification LCO 3.4.9.1 i
