l 10 ' Pressure / 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. l The following pressure-temperature limits are included in this report:
