NRC NEWS U.S. NUCLEAR REGULATORY COMMISSION 2443 Warrenville Road Lisle IL 60532 Web Site: http://www.nrc.gov E-mail: opa3@nrc.gov No. III-05-043 November 10, 2005 CONTACT: Jan Strasma (630) 829-9663 Viktoria Mitlyng (630) 829-9662 NRC BEGINS SPECIAL INSPECTION OF ELECTRICAL PROBLEMS IN SHUTDOWN AT D. C. COOK NUCLEAR POWER PLANT The Nuclear Regulatory Commission has begun a special inspection of electrical problems at the D. C. Cook Nuclear Power Station associated with the automatic shutdown of the plants Unit 2 on Tuesday, Nov. 8. The two-reactor facility, located at Bridgman, Mich., is operated by American Electric Power Co.

The Unit 2 reactor shut down automatically when the main generator failed. The main generator is conventional power plant equipment which produces electricity for distribution to the utilitys customers. The Unit 1 reactor was not affected and continued to operate at full power.

Following the Unit 2 shutdown, two separate circuit breakers failed to operate properly to provide power to certain safety systems, and the utility is continuing to investigate those failures. The plant has parallel safety systems, and all safety functions were available to the plant.

The safety of the plant was not jeopardized, said James Caldwell, NRC regional administrator. Weve sent the special inspection team to better understand the circumstances surrounding the electrical equipment failures and what corrective actions are needed.

The three-person NRC team will monitor the utilitys investigation of the failures and the resulting repairs. A report of the teams inspection findings will be issued within 30 days of the close of the inspection and will be available online in the NRCs document library at:
