SUBJECT: MONTICELLO NRC INSPECTION REPORT NO. 50-263/97014(DRP); AND

NOTICE OF VIOLATION

Dear Mr. Wadley: -

On October 13,1997, the NRC completed an inspection at your Monticello reactor facility The

'

enclosed report presents the results of that inspection.

Durirg. (.ie 6-week period covered by this inspection period, your conduct of activities at the

Monticello facility was acceptable. 2ngineering personnel demonstrated a good questioning

..ttitude in their identification of a potential non conservative setpoint for condensate storage tank

low level. Ho vever, in two cases, plant personnel did not adequately evaluate current plant

conditions This resulted in a failure to reelign the suction valves for the high pressure coolant l

injection and reactor core isolation cooling systems when a condensate storage tank level

instrumt nt was made inope.able, and in unanticipated valve movement during a surveillance

test.

In addition, a violation of NRC requirements was identified. Specifically, the inspectors identified

that the no1hwest portion of the vehicle ba'rier system did not meet regulatory requirements

The violation is .:ited in the enclosed Notice of Violation and the circumstances periaining to the

violation are described in detailin the enclosed report. The violation is a concern because it was

identified by the inspa . tors and the vulnerability was not noted during routine observations and

inspections of the system by your staff. Our understanding of your ccrrective actions taken to

correct the violation and prevent recurrence is discussed in Section S8.1 of the enclosed Report.

Therefore, you are not required to respond to this letter unless the ir; formation in Section S8.1 of

the report does not accurately reflect your coirective actions or your position, or if you choose to

provide additionalinformation.
