4 SUBJECT: NRC INTEGRATED INSPECTION REPORT NO. 50-282/306/72/96-07

' NOTICE OF VIOLATION

' Dear Mr. Watz1:

On August 15, 1996, the NRC completed an inspection at your Prairie Island.

,

Nuclear Generating Plant. The~ enclosed report presents the results of that

i- inspection.

You should note that this inspection report represents an integrated product

of a number of diverse inspections that were conducted during the inspection i

; period. The summary contaiaed in the report provides an overview of our i

assessment of your performance in the four functional areas (Operations,  ;

'

Maintenance, Engineering, and Plant Support) in which inspections were

-

performed.

,

i- During this inspection period, your conduct of activities at the Prairie l'

i Island facilities was generally characterized by proper operations,  ;

-

maintenance, engineering, and plant support activities. The response of

F operators and the emergency response organization to the partial loss of

offsite power and simultaneous dual unit trips from full power was considered

i excellent.

.

'

We are concerned with an example of poor configuration management that  :

! resulted in the violation which is being cited during this period. Both Unit 4

I hydrogen monitor channels were inoperable from March 3 through May 15, 1996,

.

because calibration equipment was degraded. This problem resulted from

changing a regolator setting on an important accident mitigation system

without adequate documentation and review. Although the issue was licensee-

identified, the NRC elected not to exercise enforcement discretion because the

degraded equipment could~have caused confusion during an accident event and

complicated recovery actions.  !
