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 have been developed using the methodology provided in the references. The following pressure-te. e limits are included in this report: r

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 +
