SUMMARY

OF OPERATING EXPERIENCE UNIT 1 The unit entered the month in Hot Shutdown due to a power supply failure in the Rod Control System continued from August.

The unit was made critical at 1010 hours0.0117 days <br />0.281 hours <br />0.00167 weeks <br />3.84305e-4 months <br /> and was synchronized to the grid at 1305 hours0.0151 days <br />0.363 hours <br />0.00216 weeks <br />4.965525e-4 months <br /> on September 1.

The unit remained on-line until September 25 at 0030 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br /> when a failure of a logic card in the Rod Control System required the unit to be shutdown.

The reactor was made critical at 2218 hours0.0257 days <br />0.616 hours <br />0.00367 weeks <br />8.43949e-4 months <br /> on September 25 and the unit was synchronized to the grid at 0240 hours0.00278 days <br />0.0667 hours <br />3.968254e-4 weeks <br />9.132e-5 months <br /> on September 26.

The period ended at a power level of 594 MWe (57% reactor power).

UNIT 2 The unit entered the reporting period at a power level of 930 MWe (87% reactor power).

On September 12 at 1050 hours0.0122 days <br />0.292 hours <br />0.00174 weeks <br />3.99525e-4 months <br /> Unit 2 tripped when an interlock key to one of the battery busses was inadvertently actuated thereby tripping the feedbreaker to the bus.

The reactor was made critical at 0745 hours0.00862 days <br />0.207 hours <br />0.00123 weeks <br />2.834725e-4 months <br /> on September 13 and the unit was synchronized to the grid at 1808 hours0.0209 days <br />0.502 hours <br />0.00299 weeks <br />6.87944e-4 months <br />, remaining on-line for the remainder of the month and ending the reporting at a power level of 1015 MWe (94% reactor power).

4.

Will ref.icling or resumption of operation thereafter require a techn3. cal specification change or other license amendn'ent?

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

If answer is no, has the relord fuel design and core configuration been revie. red :.-y your Plant Safety Review Com:.ittco to ceteriaine 'thether any unrevicu/d safety questiona are associated with the core reload (Ref. 10 CFR Section 50.59)?

If no such review has taken place, when is it

5.

Scheduled date (s) for submitting proposed li. censing action and supporting information.

6.

Important licensing consideraticas associated kith refueling, e.g.,

new or different fuel design or

October 6, 1979 is the scheduled date for the next refueling shutdown.

3.

November 14, 1979 is the scheduled date fer initial critical-ity following refueling.

4.

The reload fuel design and core configuration has undergone On-Site and Off-Site Review.

The results of this review have shown that there is no unreviewed safety questions associated with this reload and that no Technical Specifica-tion changes or license anendments are necessary.

5.

If unreviewed safety questions had arisen from the review in 4 above, then July 12, 1979 would have been the scheduled date for submitting a Reload Safety :: valuation Report on Zion Unit 1, Cycle 5.

6.

No important licensing considerations are anticipated with this refueling.

7.

The number of fuel assemblies (a) in the core is 193, and (b) in the spent fuel storage pool, which have been dis-charged from Zion Unit 1, is 130.

8.

The present licensed spent fuel pool storage capacity (shared with Zion Unit 2) is 868 fuel assemblies.

An increase in storage capacity to 2112 fuel assemblies is planned.
