| ENS 44297 | 13 June 2008 15:01:00 | A non-licensed contract employee supervisor had a confirmed positive for illegal drugs during a random fitness-for-duty test. The employee's access to the plant has been terminated. Contact the Headquarters Operations Officer for additional details. The licensee informed the NRC Resident Inspector. |
| ENS 42986 | 11 November 2006 16:31:00 | At 1243 EST, during startup activities, a manual reactor scram was inserted as a result of high conductivity in the condenser. It is believed that the high conductivity was the result of a condenser tube leak. Upon receipt of the conductivity excursion alarm, abnormal operating procedures were consulted and the manual scram was inserted. Unit 2 was at approximately 1 percent of rated thermal power and reactor pressure was approximately 100 psi. At the time of the conductivity excursion, the condensate system was not in service and, as such, reactor water chemistry was not adversely affected. All safety systems operated per design. No emergency core cooling systems (ECCS) actuated. Unit 2 will be taken to mode 4 and the necessary repairs will be completed. All control rods inserted as expected. The licensee believes there is no spread of high conductivity to adjacent systems (e.g. CRD and the CST). Confirmatory samples are in progress. Decay heat is being removed by RCIC in the pressure control mode with the intention of placing shutdown cooling in-service. The electrical system is in a normal shutdown lineup. The licensee notified the NRC Resident Inspector. |
| ENS 42724 | 25 July 2006 00:37:00 | On 7/24/06, Brunswick Unit 2 experienced a loss of Safety Parameter Display System (SPDS) capability for 12 hours and 54 minutes. Operations was informed of the loss (and restoration) of SPDS at 1700 7/24/06. Unit 2 remained at 100 percent power, steady state operation, throughout the time that SPDS was inoperable. The cause of the SPDS failure is under investigation. Note that all other emergency assessment equipment was operable during the time Unit 2 was without SPDS. SPDS was restored at 1330, 7/24/06. The licensee notified the NRC Resident Inspector. |
