SUMMARY

OF OPERATING EXPERIENCE l

UNIT 1 l

The Unit entered the reporting period in cold shutdown for the Lcontinuation of the scheduled refueling outage.

Unit I went into an.

extended outage on 11/15/89 at 1900 hours0.022 days <br />0.528 hours <br />0.00314 weeks <br />7.2295e-4 months <br />, the unit remained offline the

.l entire month.

UNIL2 The Unit entered the report period at a power level of 1071 MHe (99%

reactor power)... Unit 2 came off-line on 12/01/89 at 1022 hours0.0118 days <br />0.284 hours <br />0.00169 weeks <br />3.88871e-4 months <br /> due to leakage from loop D cold leg RCS sample valve 2SS9358C.

The reactor

-stayed critical. On 12/04/89 at 0234 hours0.00271 days <br />0.065 hours <br />3.869048e-4 weeks <br />8.9037e-5 months <br />, Unit 2 was synchronized to 1

the' grid-The Unit ended the report period at a power level of 1075 MHe (99% reactor power) and having an availability factor of 91.4%.

4.

Will refueling or resumption of operation thereafter require a

- technical s;;ecification change or other license amendment?

l9 If answer is yes,:what, in general, will_ these be?

If answer is no, has the reload fuel design and core configuration L

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)?

If no such review has taken-place, when is it scheduled?

5.

Scheduled-date(s) for submitting proposed licensing action and supporting information.

6.

Important licensing considerations associated with refueling, e.g.,

-new or different fuel design or supplier, unreviewed design or s,

performance analysis methods, significant changes in fuel design, new H

operating procedures.

7.

The number of fuel assemblies: (a) in the core and (b) in the spent fuel storage pool.

8. -

The present licensed spent fuel pool storage capacity and the size of any increase in licensed storage capacity that has been requested or is planned,.in number of fuel assemblies.

9'

-The projected date of the last refueling that can be discharged to the spent fuel pool assuming the present licensed capacity.
