PRESSURE / TEMPERATURE LIMITS (Continued)

The operating limit curves of Figure 3.4.6.1-1 are derived from the fracture i

4 toughness requirements of 10 CFR 50 Appendix G and ASME Code Section III,'

Appendix G.

The curves are based on the RTer and stress intensity factor information for the reactor vessel components.

Fracture toughness limits and the basis for compliance are more fully discussed in FSAR Chapter 5, Para-l graph 5.3.1.5, " Fracture Toughness."

The reactor vessel materials have been tested to determine their initial RTet. The results of these tests are shown in Table B 3/4.4.6-1.

Reactor operation and resultant fast neutron, E greater than 1 MeV, irradiation will cause an increase in the RTer. Therefore, an adjusted reference temperature, based upon the fluence, nickel content and copper content of the material in question, can be predicted using Bases Figure B 3/4.4.6-1 and the recommenda-tions of Regulatory Guide 1.99, Revision 2, " Radiation Embrittlement of Reactor Vessel Materials." The pressure / temperature limit curve, Figure 3.4.6.1-1, curves A', B' and C', includes an assumed shift in RTer for the conditions at 10 EFPY.

In addition, intermediate A' curves have been provided for 6.5 and 8.5 EFPY.

l The A, B and C limit curves are predicted to be bounding for all areas of the RPV until 1 EFPY when the beltline materials RTer will shift, due to neutron fluence, and the beltline curves will intersect the non-beltline discontinuity curves.

The actual shift in RTer of the vessel material will be established period-ically during operation by removing and evaluating, in accordance with 10 CFR Part 50, Appendix H, irradiated reactor vessel flux wire and charpy specimens installed near the inside wall of the reactor vessel in the core area. Since the neutron spectra at the charpy specimens and vessel inside radius are essentially identical, the irradiated charpy specimens can be used with con-fidence in predicting reactor vessel material transition temperature shift.

The operating limit curves of Figure 3.4.6.1-1 shall be adjusted, as required, on the basis of the flux wire and charpy specimen data and recommendations of Regulatory Guide 1.99, Revision 2.

The pressure-temperature limit lines shown in Figures 3.4.6.1-1, curves C, and C', and A and A', for reactor criticality and for inservice leak and hydrostatic testing have been provided to assure compliance with the minimum temperature requirements of Appendix G to 10 CFR Part 50 for reactor criticality and for inservice leak and hydrostatic testing.

The number of reactor vessel irradiation surveillance capsules and the frequencies for removing and testing the specimens in these capsules are pro-vided in Table 4.4.6.1.3-1 to assure compliance with the requirements of Appendix H to 10 CFR Part 50.
