1.0 Pressure / Temperature Limits This Pressure / Temperture Limits Report for CR 3 has been prepared in accordance with the requirements of Technical Specification Section 1.1.

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

The following pressure temperature limits are included in this report.

1) Allowable plant heatup and cooldown rates.

2) Plant heatup P/r cunt

3) Plant cooldown P/P curve

4) Plant inservice leak and hydrostatic ter.ing P/r curve i
