NRC MONTHLY OPERATING REPORT-OPERATING

SUMMARY

NOVEMBER 1985 UNIT TWO The unit began the_ month at 75% power to accomidate condenser' tube leak search; Temporary plugs had been installed in a portion of the "B" condenser North waterbox in an attempt.to isolate the leaking tubes. At 0701 hours0.00811 days <br />0.195 hours <br />0.00116 weeks <br />2.667305e-4 months <br /> on the first, power was increased to 95% with no indication of a tube leak.. Power was reduced to 75%, and-' half of the temporary plugs were removed. A power increase was started at 2231 hours0.0258 days <br />0.62 hours <br />0.00369 weeks <br />8.488955e-4 months <br /> on the first, and 100%

power was achieved at_0110 hours on the second. With no tube leak indication, power was once again decreased to 75% power, and half of the remaining tempor.ary plugs were removed.

This~ evolution of power reductions to 75% power and increases to ~100% power was performed three more times until the leaking tube was identified and removed from service. The unit reached 100% power at 0040 hours4.62963e-4 days <br />0.0111 hours <br />6.613757e-5 weeks <br />1.522e-5 months <br /> on the fifth and remained thereLuntil 1032~

hours on the twenty-sixth, when a stator cooling pump tripped causing'a turbine runback to ~69% power on high stator cooling temperature.

The plant was stabilized and a power increase was started.

The unit reached 100%

power at 1455 hours0.0168 days <br />0.404 hours <br />0.00241 weeks <br />5.536275e-4 months <br /> on the twenty-sixth and remained there through the end of the month.

REFUELING INFORMATION

~

' 1.-

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

-Scheduled datelfor next refueling' shutdown.. Cycle 5 was' initiated in~

May 1985.

The next refueling shutdown is' scheduled for' June 1986.

3.

Scheduled date for restart following refueling.L Aiscust 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 was installed in November after Technical Specification approval.

5.

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

If required, submission will be by May: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.

The fresh fuel will have a modification to the CEA auide tube wear sleeves which has been reviewed.

(Ref. SER dated September 7. 1984-for C-E Report LD-84-043).

A longer cycle and a chance -in in-core fuel management from out-in-in to in-in-out are also 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 ofe any increase in. licensed storage capacity that-has been requested or is.

planned, in number of. fuel assemblies.

-present 988 increase size by O' 9.

The projected date of the last refueling that can be discharged'to-the '

spent fuel pool assuming the present licensed capacity.
