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
