EXHIBIT I REACTOR PRESSURE VESSEL PURCHASE SPECIFICATION 21A1111 APPENDIX K K.I-1 REV. 25, APRIL 2015

EXHIBIT I - REACTOR PRESSURE VESSEL PURCHASE SPECIFICATION 21A1111 The power rerate design requirements are unchanged from the original design requirements specified in Exhibit I, Section 5 (i.e., design pressure of 1250 psig at bottom of the reactor vessel, design temperature of 575°F).

The power rerate normal operating pressure is increased from 1005 psig to 1035 psig at top of reactor vessel. The normal operating temperature is increased from 547°F to 551°F.

The operating shroud support pressure differentials provided in Appendix K, Exhibit I, Section 7.5.1 are increased from 34.0 and 21.85 to 35.68 and 26.32 psid for power rerate.

Estimates for reactor vessel irradiation at the end of 60 years have been recalculated based on actual data obtained from the reactor vessel surveillance specimens which were removed and analyzed. The updated information presented in Sections 4.2.4 and 4.2.5 supersede the information contained in Exhibit I Section 5.1.11.

Expected operating cycles for which fatigue has been evaluated are listed in UFSAR.

The Unit 2 and 3 TPO power rerate did not change the normal operating pressure or temperature for the reactor vessel.

The extended power uprate (EPU) did not change the normal operating pressure or temperature for the reactor vessel. The design pressure differentials across the shroud support and shroud provided in Appendix K, Exhibit I, Section 7.5.12 are not exceeded for EPU.
