Observations and Findinas During the inspection, the inspector reviewed licensee Condition Reperts 1998-0181 and 1998-0214 which documented the results of 1998 weekly load testing of the security diesel generator. The condition reports indicated that during weekly performance testing, the security diesel generator had automatically shut down (tripped) after several minutes of operation, due to high water temperature.
During this inspection, on September 2,1998, the licensee conducted a load test of the security diesel generator after measures had been implemented to improve the air flow inside the diesel generator building. The generator operated satisfactorily for 1-1/2 hours, after which the licensee terminated the load test.
During this inspection, the licensee stated that its identified actions to permanently improve the air flow inside the diesel generator building should resolve future
" overheating" problems. During the exit meeting, the inspector discussed the in.portance of the licensee's immediate completion of these permanent improvements.
c.
Conclusions During weekly testing, the security diesel generator overheated and automatically shut down. Temporary measures to improve air flow ins,ide the diesel generator building improved operations. Permanent measures to improve building air flow are in progress.
S3 Security and Safeguards Procedures and Documentation S3.1 Security Event Logs a.
Inspection Scope (81700)
The inspector reviewed safeguards event logs and security incident reports to determine compliance with the requirements of 10 CFR 73.21(b) and (c),10 CFR 26.73, and the physical security plan.
b.

S8.1
[ Closed) Licensee Event Report 313/98-S01-00 Identification of Foreian Materialin Main Turbine Generator Bearinos i
in accordance with 10 CFR 73.71(b )(2), the licensee telephonically reported to the NRC
!
on April 7,1998 (Event No. 34033) that during disassembly of the Unit 1 main turbine i
generator, as part of a scheduled refueling outage, foreign material was discovered in the No. 4 bearing between the shaft and bearing on the oilinlet side of the bearing. The items appeared to be cut sections of threaded carbon steel bolts, one piece measuring 1 inch by 3/8 inch and the other measuring 3/4 inch by 1/8 inch. On April 14,1998, the i
licensee identified additional foreign material in bearing No. 7. The materialincluded a 13/4-inch and a 3/8-inch washer imbedded in the babbit of the bearing. No additional foreign material was identified in the other bearings inspected.
<
l On May 4,1998, the licensee submitted its event report. In this report, the licensee i
!
stated that they could not determine if the foreign material was introduced accidentally l
or intentionally and, therefore, the root cause could not be conclusively determined.
NRC Inspection Report 50-313/9804; 50-368/9804 dated June 4,1998, prepared by the NRC resident inspectors reviewed the overall event. Additionally, this report stated that additionalinspection will be conducted to review the results of the licensee's security investigation as part of the closeout inspection for the safeguards event report.
l During this inspection, the inspector reviewed the licensee's completed (security)
investigation of this event. During the investigation,62 workers involved in the
'
1R13 outage were identified as having worked on, or had been in the area of, the Unit 1 main turbine generator. Representatives from Entergy Corporate Security sent letters to
,
these 62 workers asking them to contact the investigators.
I l
During its investigation, the licensee interviewed 52.odividuals; the remaining l
10 individuals could not be contacted. During each of the 52 interviews, the individuals l
were appraised of the identified foreign material and asked if they had any knowledge regarding this matter. None of the individuals contacted provided any information. The licensee's investigation of this event failed to identify any substantial information. The licensee determined that this event had minimal actual safety significance and that the
,
l equipment involved in the event was not classified as vital equipment.
l S8.2 (Closed) Violation 313/9814-01: 368-9814-01: Failure of an Intrusion Alarm to Provide l
An Audible Sianal l
l During a previous security inspection, the inspector determined that one of the I
licensee's intrusion detection systems had failed to provide an audible alarm signal upon recognizing that an unauthorized individual had used an invalid key card in a security card reader door. Only a visual alarm signal had been provided.

alarm signal would be added to the intrusion detection system by July 30,1998.
During this inspection, the inspector verified through observation and testing that the _
,
licensee's corrective action had been completed and that the intrusion detection system had been modified to annunciate an audible alarm signal whenever an invalid key card j
was inserted into a card reader at a security door.
