- 1. Scheduled date for next refueling shutdown.
November 27, 1988
- 2. Scheduled date for restart following refueling.
Under Evaluation
- 3. Will refueling or resumption of operation thereafter require a Technical Specification change or other license amendment?
Yes.
What will these be?
Proposed Technical Specification Changes are as follows:
Proposed Change Number (PCN) 169 revises Technical Specification (TS) 3.5.2, "Control Group Insertion Limits" to delete Control Group 1 allowable insertion and to incorporate Standard Technical Specification (STS) format and Action Statements.
Proposed Change Number (PCN) 182 revises TS 4.16, "Inservice Inspection of Steam Generator Tubing" to include an alternate tube plugging criteria.
Proposed Change Number (PCN) 184 revises the demonstration of Control Element Assembly trippability to 7 days prior to reducing shutdown margin below the limits.
Proposed Change Number (PCN) 185 revises Appendix A TS 2.1 and 3.5.1 to include the revised steam/feedwater flow mismatch trip setpoints and associated Limiting Conditions for Operations.
Proposed Change Number (PCN) 186 revises TS 4.2, "Safety Injection and Containment Spray System" periodic testing to include surveillance of a planned modification to add Safety Injection/Feedwater Pump trip on low-low Refueling Water Storage Tank (RWST) level.
Proposed Change Number (PCN) 194 modifies the positive isolation barrier requirements in TS 3.3.2 due to modifications to include MOV-358 onto the Uninterruptible Power Supply (UPS) for MOV-850C.
