SUMMARY

OF OPERATING EXPERIENCE UNIT 1 The unit entered the reporting period at a power level of 1048 MWe (99%

. reactor power) ion March lith at 1543. hours. While returning to a normal line up, after performing reactor protection logic testing, a turbine trip / reactor trip occurred ~due to an improperly made up' cell switch -in the reactor trip breaker. On March 16th at 1927 hours0.0223 days <br />0.535 hours <br />0.00319 weeks <br />7.332235e-4 months <br />, the_ unit was made

. critical and on March 17th at 1755-hours the unit was synchronized to the

' grid. The unit 1remained on line the remainder of.the. report period ending at a power level of 1052 MWe (99% reactor power) and having an availability. factor of 80.3%

Unit 2

-The unit entered the reporting period at a power level of.452 MWe (47%

reactor power). Ramping down of the unit began February 28th at 0245 hours0.00284 days <br />0.0681 hours <br />4.050926e-4 weeks <br />9.32225e-5 months <br /> for turbine overspeed test. On March 1st at 0019 hours2.199074e-4 days <br />0.00528 hours <br />3.141534e-5 weeks <br />7.2295e-6 months <br /> the unit was critical and on March 2nd at 1835 hours0.0212 days <br />0.51 hours <br />0.00303 weeks <br />6.982175e-4 months <br /> the unit was' synchronized ~to the grid. 'On March 24th at lill hours, while performing reactor protection system logic testing,' the installation of the instrument power fuses-on both source range channels created electrical disturbances which caused a "High Negative Flux Rate" trip on two power ranges resulting .in a Reactor Trip. On March 25th at 0406 hours0.0047 days <br />0.113 hours <br />6.712963e-4 weeks <br />1.54483e-4 months <br /> the unit was made critical and at 1050 hours0.0122 days <br />0.292 hours <br />0.00174 weeks <br />3.99525e-4 months <br /> the. unit was synchronized to the grid._ The unit remained on line.  ;

the remainder of the report period ending at a power level of 1087 MWe (99% reactor power) and having an availability factor of 91.1% '-

REFUELING INFORMAIION REQUEST Questions: s

11. Name of facility.

, 2._ _ Scheduled date for next refueling shutdown.

I.

.- 3. Scheduled date for restart following refueling.

4. Will refueling or resumption of operation thereafter require a technical- specification change or other license amendment?

If answer is yes, what, in general, will these be?

t l 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)?

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

5. Scheduled ~ date (s) for submitting proposed licensing action and

. supporting information.

6. Llmportant licensing considerations associated with refueling, e.g., new or dif ferent fuel design or supplier, unreviewed design or performance analysis methods, significant changes in fuel design, new 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.
