SUBJECT:

BRAIDWOOD INSPECTION REPORT 50-456/99011(DRP); 50-457/99011(DRP)

Dear Mr. Kingsley:

On July 6,1999, the NRC completed an inspection at your Braidwood Units 1 and 2 reactor

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

During the 6-week period covered by this inspection, your conduct of activities was generally

characterized by safety-conscious' operations, sound engineering and maintenance practices,

and careful radiological work controls.

In the enclosed report is documented the equipment failure of some essential service water

isolation ball valves. The poor material condition of these valves resulted in the unnecessary

isolation of an entire train of the emergency core cooling system for 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />. In the past few

months equipment failures have resulted in two unusual events, two reactor trips, two

unscheduled plant shutdowns, and the need for a Notice of Enforcement Discretion to prevent a

third reactor shutdown. Although we recognize that the number of non-outage work requests

has been greatly reduced, these problems indicate a possible reduction in the material

condition of the station.

Based on the results of this inspection, the NRC has determined that two violations of NRC

requirements occurred. These violations are being treated as Non-Cited Violations (NCVs),

consistent with Appendix C of the Enforcement Policy. These NCVs are described in the

j

subject inspection report. If you contest the violation or severity level of these NCVs, you

should provide a response within 30 days of the date of this inspection report, with the basis for

your denial, to the Nuclear Regulatory Commission, ATTN: Document Control Desk,

Washington DC 20555-0001, with copies to the Regional Administrator, Region lil, and the

Director, Office of Enforcement, United States Nuclear Regulatory Commission, Washington,

DC 20555-0001.
