SUBJECT:
FERMI INSPECTION REPORT 50-341/98015(DRP)
Dear Mr. Gipson:
On November 9,1998, the NRC completed an inspection at your Fermi 2 reactor facility. The
enclosed report presents the results of that inspection. During the 7-week period covered by
this inspection period, your conduct of activities was generally characterized by
safety-conscious operations, sound engineering, and good maintenance practices.
During the inspection, a number of personnel errors occurred during the refueling outage.
Consequently, the station error free clock was reset 11 times during the outage due to -
personnel errors. An example of a personnel error resulted in the issuance of a non-cited
violation for the failure to follow an operating procedure and the deenergizing of an engineored
safety features bus. The inspection also identified a concern regarding the failure to correctly
schedule a surveillance test on the primary containment radiation monitoring system. Your
identification of a failure to perform the surveillance test within the surveillance interval was
determined to be a non-cited violation of the Technical Specifications for the failure to adhere to
the Offsite Dose Calculation Manual requirements. Finally, concerns were identified regarding
the quality of the ma'atenance procedures for the high pressure turbine control valves.
Although these are nasafety-related pieces of equipment, insufficient torque applied to
. portions of the valve linkage resulted in unanticipated cycling of the valve internals during valve
manipulation. The valve cycling caused significant fluctuations in reactor power level and
caused operators to insert manual scrams on two occasions. These concerns indicate that
continued attention is needed to reduce personnel errors and to control maintenance activities.
