SUBJECT:

PRAIRIE ISLAND INSPECTION REPORT 50-282/98008(DRP);

50-306/98008(DRP)

Dear Mr. Wadley:

On June 18,1998, the NRC completed an inspection at your Prairie Island Nuclear Generating

Plant. The enclosed report presents the results of that inspection.

During the 5-week period covered by this inspection, operations activities, including a significant

power reduction and subsequent ascension, as well as a plant startup from cold shutdown

conditions, were performed well, Maintenance and surveillance activities observed were also

performed well except that there was unexpected interference between two jobs in the same

area resulting in water entering a dewatered circulating water bay. Two operability evaluations

i

performed by engineering personnel were reviewed. One was comprehensive and adequately

- justified interim operability of steam exclusion dampers.' The other was weak in that a scenario

that could have resulted in unnecessarily complicating the response to a reactor trip was not

addressed. No violations were identified during the inspection.

1

In accordance with 10 CFR 2.790 of the NRC's " Rules of Practice," a copy of this letter and its

enclosure will be placed in the NRC Public Document Room.

'

Sincerely,

i

/s/ Marc L. Dapas for
