. j 1.0 Press:re/ Temperature Limits (Ref.4)

This Pressure-Temperature Limits Report for CR3 has been prepared in accordance with the requirements ofTechnical Specification Section 1.1 and 5.6.2.19. The pressure / temperature (Pff) limits have been developed using the methodology provided in the references (Ref.1, Ref.2, Ref.3). Additional limits have been included which support the LTOP Technical Specification 3.4.11.

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 5 LTOP P/T curves 6 Composite P/T curve 2.0 Fluence and Limiting Material Information (Ref.5)
