r The actual temperature shift of the vessel material will be established

~

periodically during operation by removing and evaluating reactor vesnt material irradiation surveillance specimens installed near the inside wall of the reactor

vessel-in the core area. Since the neutron spectra at the irradiation samples

- and vessel inside-radius are identified by a specified lead factor, the measured temperature shift for a sample is an excellent indicator of the effects of power i

operation on the adjacent section of the reactor vessel. If the experimental

,terparature shift (at the 30 ft-lb level) does not substantiate the predicted shift, new prediction curves and heatup and cooldown curves must be developed.

The pressure-temperature limit lines shown on Figure 15.3.1-1 for reactor criticality and for inservice leak and hydrostatic testing have been provided to

assure compliance with the minimum temperature requirement.s of Appendix G to 10 CFR 50 for reactor criticality and for inservice leak and & drostatic testing.

The reactor vessei materials kurveil ance capsule removal schedules have been developed based upon the requirements of the Code of Federal Rcquiations, _

Title 10, Part 50, Appendix H and with consideration of ASTM Standard E-185-82.

When the capsule lead factors are considered, the scheduled removal dates j

accommodate the weld data needs of all the participants in the Babcock and Wilcox Master Integrated Reactor Vessel Surveillance Program. Additionally, the

schedule will-provide plate / forging material data as well as fluence data

corresponding to the expiration of the current licenses and of any future license
