SUBJECT:

PEACH BOTTOM ATOMIC POWER STATION - NRC INSPECTION REPORT 05000277/2003012, 05000278/2003012

Dear Mr. Skolds:

On June 27, 2003, the NRC completed a team inspection at the Peach Bottom Atomic Power Station. The enclosed report documents the inspection findings which were discussed on June 27, 2003, with Messrs. R. West and J. Stone, and other members of your staff.

This inspection was an examination of activities conducted under your license as they relate to the identification and resolution of problems, compliance with the Commissions rules and regulations, and with the conditions of your license. Within these areas, the inspection involved examination of selected procedures and representative records, observation of activities, and interviews with personnel.

On the basis of the samples selected for review, the team concluded that in general, problems were properly identified, evaluated and corrected. The team identified one self-revealing finding of very low safety significance (Green) concerning the failure to properly correct an equipment deficiency that subsequently resulted in a challenge to the plant and to operators. Specifically, a solenoid associated with a reactor feed pump turbine (RFPT) overspeed trip device exhibited degradation during RFPT overspeed testing on two occasions, however, your staff failed to determine the root cause for this problem until a third problem occurred that resulted in a RFPT trip and plant transient.

In addition, several examples of minor equipment problems were identified by the team that were not previously entered into the corrective action program. Further, examples were identified where problem evaluations were narrowly focused or did not contain sufficient technical bases for the associated conclusions; and there were some instances where corrective actions were not aggressive in resolving certain problems in a timely and effective fashion. None of these deficiencies resulted in a challenge to system operability.

Mr. John In accordance with 10 CFR 2.790 of the NRCs "Rules of Practice," a copy of this letter and its enclosure will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRCs document system (ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

Sincerely,

/RA/
