SUMMARY
JUNE 1984 UNIT 1 The unit began the month at 96% power.
The unit was-power limited due to the high operating level in the "A" Steam Generator.
Over the next few weeks, the plant was gradually backed down in power until the unit was operating at 94% power.
At 1800 hours0.0208 days <br />0.5 hours <br />0.00298 weeks <br />6.849e-4 months <br /> on June 25, the unit began a power reduction to 45% in order
- to removeLthe "A" Main Feedwater Pump from service for minor repairs to the control oil system. Upon completion of the repair work, at 1000 hours0.0116 days <br />0.278 hours <br />0.00165 weeks <br />3.805e-4 months <br /> on June 26th, the unit was returned to 93% power.
The unit remained at that power level through the end of the month.

Will refueling or resumption of operation thereafter require a technical specification change or other license amendment? It answer is yes, what, in general, will there be? If answer is no, has the reload fuel design and core configuration been reviewed by your Plant Safety Review Committee to determine whether any unreviewed safety questions are associated with the core reload (Ref. 10 CFR Section 50.59)?
Yes, Reload Report and associated proposed Technical Specification change.

Important licensing considerations associated with refueling, e.g., new or different fuel design or supplier, unraviewed design or performance analysis methods, significant changes in fuel design, new operating procedures.
Yes, the reload analysis will be done using newly developed thermal hydraulic codes.
Babcock & Wilcox will be submitting Topical Reports on the new codes for NRC review prior to September 1,1984.
