REFUELING INFORMATION 1.

Name of facility.

Arkansas Nuclear One - Unit 2 2.

Scheduled date for next refueling shutdown. 03-01-80 3.

Scheduled date for restart following refueling.

06-01-80 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?

If answer is no, has the reload fuel design and core configuration been reviewed by your Plant Safety Review Connittee to determine whether any unreviewed safety questions are associated with the core reload (Raf. 10 CFR Section 50.59)7 Yes - Description of effects of new core loading 5.

Scheduled date(s) for submitting proposed licensing action and supporting information. 1-01-80 6.

Impo:: tant licensing considerations associated with refueling, e.g.,

new or different fuel design or supplier, unrevi~ewed design or performance analysis methods, significant changes in fuel design, new operating procedures.

None 7.

The number of fuel assemblies (a) in the core and (b) in the spent fuel storage pool. a) 177 b) 0 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.

OPERATING SIMtARY - OCTOBER, 1978 UNIT II The unit remained shut down until 10/1/78, when the heatup began to continue the Post-Core Hot Functional Test.

On 10/5/78, the pressurizer code relief valve developed a leak during setpoint testing. The valve was temporarily gagged, allowing the valve to cool and reseat (Reference R.O. 50-368/78-8).

On 10/6/78, an Emergency Feedwater valve's hydraulic pump motor failed, making the valve inoperable. Repairs were made and the emergency feedwater flowpath was reestablished (Reference R.O. 50-368/78-9).

The unit was cooled down on 10/14/78 to allow the change out of a partially shorted upper gripper solenoid coil on a control drive element assembly.

Heatup began on 10/29/78 and reached Mode 3 operation two days later. Post-Core Hot Functional Testing continued the remainder of the month.

OPERATING SUIMARY - SEPTEMBER, 1978 UNIT II Post-core Hot Function Testing began on 9/4/78. On 9/12/78, the condensate storage tank level had reduced to approximately 35% due to an abnormally high use rate. It was not brought to >SO% within the required 7 days. A contractor was brought in to assist in making the required condensate

~

(Reference R.O. 50-368/78-3).

On 9/16/78, following a Unic I plant trip, Fraakers feeding both engineering safeguard busses tripped when off-site power supply for both units transferred to Start-Up transformer #2.

The emergency diesel generators started, but inverter malfunctions caused the inverters to transfer to their alternate source position before the diesel generators were at speed and operable.

In the alternate source position the inverters are aligned exclusively to the diesel generators. Since the alternate source of power to the inverters was not operable, vital instrumentation was without power and a full actuation of the engineering safeguards systems resulted. This included: 1) Reactor Building Spray System actuation, wetting down all equipment, 2) Isolation of component cooling water to the reactor coolant pump seals, 3) Sodium Hydroxide admitted into the Shutdown cooling system. All equipment and components in the Reactor Building was inspected and cleaned, the reactor coolant pump seals were replaced as necessary, and an engineering evaluation of the high chloride concentration in the Reactor Coolant Systems was performed (Reference R.O.

50-368/78-4, 78-5, 78-6 and 78-7).

The Unic remained shut down the rest of the month, s
