- 1. Scheduled date for next refueling shutdown.
Cycle 8 refueling outage is forecast for January 15, 1995.
- 2. Scheduled date for restart following refueling.
Restart from Cycle 8 refueling outage is forecast for March 15, 1995.
- 3. Will refueling or resumption of operation thereafter require a Technical Specification change or other license amendment?
Yes What will these be?
A.
A proposed change to the Technical Specifications will be requested which will revise the minimum water level in the refueling cavity with only one train of shutdown cooling operable.
B.
A proposed change to the Technical Specifications and an exemption from 10 CFR 50 Appendix J will be requested to permit deferring the Integrated Leakrate Testing.
C.
A proposed change to the Technical Specifications will be requested to revise the allowed Linear Heat Rate frcm 13.9 to 13.0 kw/ft.
D.
A proposed change to the Final Safety Analysis has been requested to remove the diversity requirement of the pressurizer pressure transmitters providing input to the shutdown cooling open permissive interlock.
E.
Proposed change to the Technical Specifications (PCN 431), revising the automatic reset of the low pressurizer pressure bypass, will be revised to simplify the request.
