Observation of Fuel Handling Activities i

The inspector observed fuel handling operations in the refueling cavity, spent fuel pool, and the Control Room frequently during this inspection, including portions of all three shifts.

The following items were reviewed.

Proper core monitoring performed

-

'

Fuel handling, fuel accountability and sipping conducted

-

in accordance with approved procedures r

Core internals stored to protect from damage

-

Housekeeping and cleanliness conditions acceptable

-

Proper make-up and qualification of refueling crews

Except as noted below, no items of noncompliance were identified.

,

During observation of fuel handling operations on the third j

shift, January 21, 1980, the inspector noted that the source

!

range audible count rate monitor was not operating in the re-i fueling cavity area during core alterations as required by

Procedure 10-1, " Core Reloading", and Technical Specification - 5.8.

Corrective action was taken to increase the volume of the audible neutron count rate and was found acceptable during i

a subsequent inspection of the refueling cavity area prior to

-

completion of the inspection.

This item is an infraction (309/80-01-01).

I i

During observation of activities in the refueling cavity on j

the same shift, the inspector noted that the refueling machine

operator was not wearing cotton gloves as required by Radiation i

Work Pennit 80-1-465 of January 21, 1980, procedure 9.1.10,

" Radiation Work Permits", and Technical Specification 5.8.

Corrective action was taken and reinspected prior to the end

of the inspection and found to be acceptable.

This item is an i

infraction (309/80-01-02).

PORC and NSARC Review Functions I

The Plant Operations Review Comittee (PORC) and Nuclear Safety

Audit and Review Committee (NSARC) review functions were reviewed i

by the inspector to verify that:

l

,

!

-

All PORC and NSARC meetings were convened during the previous

year at the frequency required by the Technical Specifications;

'

The meeting membership of PORC and NSARC meetings satisfied

-

i the quorum requirements of the Technical Specifications;

Noncompliances with Technical Specfications or rules and

-

regulations were reviewed as required by the Technical Specifications; i

Licensee Event Report (LER) Followup The inspector reviewed LERs received in RI office to verify that details of

,

the event were clearly reported including the accuracy of the description of cause and adequacy of corrective action.

The inspector also detemined

!

whether further infomation was required from the licensee, whether generic i

implications were indicated, and whether the event warranted on site followup.

l During on site followup, the inspector verified that reporting requirements

!

of Technical Specifications and Regulatory Guide 1.16 had been met, that appmpriate corrective action had been taken, that the event was reviewed

by the licensee as required, and that continued operation of the facility

!

was conducted within Technical Specification limits.

The review included l

discussions with licensee personnel, review of PORC meeting minutes, Plant

-

Infomation Reports (in-house reports), and applicable logs.

The following

!

LERs were reviewed.

79-29/99X-0 and 79-30/99X-0, High Dose Equivalent Iodine-131 in the

-

Reactor Coolant System (RCS)

'

[

The inspector reviewed RCS chemistry records for the period December 10, 1979 - January 21, 1980 to check the trends of the concentration of the iodine isotopes. The inspector also witnessed the fuel sipping operation being perfomed in the Spent Fuel Pool.

At the time of the inspection a j

small number of the sampled fuel assemblies indicated failed fuel pins.

A

further report will be submitted to the NRC upon completion of the fuel l

inspection.

79-31/32, Failed RPS Matrix Relays f

-

The inspector reviewed the results of test procedure 4-44, " Matrix Relay as noted in detail two to verify that the two matrix relays that Testing"(AC-1 and BD-3) would not have prevented a reactor trip.

failed Followup inspection in this area covering the increased test frequency will continue until the substitute relays have been procured and installed.

Reactor Coolant Cystem High Chloride Levels

During a review of Reactor Coolant System Chemistry logs and discussions l

with a plant chemist, the inspector noted abnormally high chloride concentration in the reactor coolant (as high as 3 ppm).

The logs indicate that the chloride intrusion occurred after the plant was in cold shutdown and did not represent a violation of a limiting condition for operation. Additional followup on this item will be

,

performed in a subsequent inspection to review the cause, status of cleanup which must be complete prior to starting up, and steps taken to prevent recurrence.

(309/80-01-04)

6.

In-Office Review of Periodic Reports

!

The inspector reviewed the November and December 1979 Monthly Operating Reports received in the RI office to verify that reporting requirements were met.

No inadequacies were identified.

9.

Exit Interview l

The inspector met with licensee representatives (see detail 1 for attendees) at the conclusion of the inspection to discuss the scope and findings of the inspection as detailed in this report.
