SUBJECT: DUANE ARNOLD INSPECTION REPORT 50-331/99003(DRP)

Dear Mr. Franz:

This refers to the inspection conducted on March 3 through April 13,1999, at the Duane Amold

Energy Center (DAEC) facility. The NRC conducted a routine safety inspection. The enclosed

report presents the results of this inspection.

During this 6-week inspection period, your conduct of activities at the DAEC facility was

characterized by safe operational performance. No violations of NRC requirements was

identified. However, an inadequate implementation of a modification to the "A" reactor water

cleanup pump installed this year resulted in an insufficient oil level and subsequent bearing

failure.

In accordance with 10 CFR Part 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,

Original signed by

Melvyn N. Leach, Chief

Reactor Projects Branch 2
