l PRESSUREffESIPERATURE LIMITS REPORT REVISION 1 l Referencing Improved Technical Specifications

, l 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 and 5.6.2.19. The pressure / temperature (P/T) limits .. ave 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) P. ant inservice leak and hydrostatic testing P/T curve 2.0 Fluence and Limiting Material Infonnation
1. Predicted intide surface peak fluence at 15 EFPY : 0.499 E19 n/cm2
2. Limiting Material : WF-70 (Upper to Lower shell circumferential weld)
3. Adjusted Reference Temperature (ART): 203 deg F @ 1/4T 171 deg F @ 3/4T 3.0 References l

V Al.l.0WAlli.E IIEATUP AND C001.DOWN RATES

a. A maximum heatup of 50*F in any one hour period,
b. For the temperature ranges specified below, the cooldown rates are:
1. T > 280'F s 50'F in any 1/2 hour period, ii. 280*F 2 T > 150*F s 25'F in any 1/2 hour period, iii. 150*F 2 T s 10'F in any I hour period and,
c. A maximum temperature change ofless than or equal to 5*F in any one hour period during hydrostatic testing operations above system design pressure.

These limits are referred to by Technical Specification 3.4.3.

3. Margins are included for the pressure differontial between point of system pressure measurement i

and the pressure on the reactor vessel region controlling the limit curve. Additional margins for instremont uncertainty are not included and must be applied to operating proceduros based on the specific instruments being used to monitor the RCS conditions.

4. A maximum step temperature change of 25'F is allowable when removing all RC pumps from operation with the DHR system operating. The step temperature change is defined as the RC ,

temp, Tc, (prior to stopping all RC pumps) minus the DHR return temp, Tout (after stopping all RC oumps).
