SUMMARY

j June 1985 UNIT TWO t

l

.The' unit began the month holding at 50% power for physics testing.

On the fifth of June,' the unit reach 95% power and was held there due to moisture separator reheater relief valve problems.

At 0409 hours0.00473 days <br />0.114 hours <br />6.762566e-4 weeks <br />1.556245e-4 months <br /> on the 8th, the unit was taken off-line for repairs to the moisture separator reheater i

relief valve.

At 0059 hours6.828704e-4 days <br />0.0164 hours <br />9.755291e-5 weeks <br />2.24495e-5 months <br />;on June 13th, the unit reached 100% power but l

was taken off line at 2230 hours0.0258 days <br />0.619 hours <br />0.00369 weeks <br />8.48515e-4 months <br /> that same day due to high exciter bearing vibration..The unit reached 100% power at 1503 hours0.0174 days <br />0.418 hours <br />0.00249 weeks <br />5.718915e-4 months <br /> on June 16th.

On the 17th high vibration on the "B" main feedwater pump forced tne unit to decrease power to 80%.

Later that day, COLSS was declared inoperable requiring the unit'to reduce power to 72.5% to maintain a Technical Specification margin.

On June 20th power was increased to ~ 80%.

At 2102 hours0.0243 days <br />0.584 hours <br />0.00348 weeks <br />7.99811e-4 months <br /> on the 29th the unit reached 100% power.and remained there through the end of the month.

DATE:

June 1985 REFUELING INFORMATION 1.

Name of facility: Arkansas Nuclear One - Unit 2 2.

Scheduled date for next refueling shutdown.

Cycle 5 was initiated in May 1985. The next refueling shutdown is scheduled for May 1986.

3.

Scheduled date for restart following refueling. July 1986 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 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)?

Cycle 6 details are still being reviewed.

A modified CPC program will be installed during cycle 5.

i 5.

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

If required, submission will be by April 1986.

6.

Important licensing considerations associated with refueling, e.g., new or different fuel design or supplier, unreviewed design or performance analysis methods, significant changes in fuel design, new operating procedures.

A longer cycle and a change in in-core fuel management from out-in-in to in-in-out are planned.

7.

The number of fuel assemblies (a) in the core and (b) in the spent fuel storage pool, a) 177 b) 168 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, present 988 incre'ase size by 0 9.

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