Abstract
On January 26, 2003, at 0426 hours0.00493 days <br />0.118 hours <br />7.043651e-4 weeks <br />1.62093e-4 months <br />, Donald C. Cook Nuclear Plant (CNP) Unit 2 was manually shut down in accordance with Technical Specification 3.8.1.1, A.C.
Sources, Action b, and normal plant operating procedures, due to the CD Emergency Diesel Generator (EDG) being out of service.
All remaining safety related equipment performed as required and no anomalies were noted.
This event is being reported in accordance with 10 CFR 50.73(a)(2)(i)(A) and NUREG-1022, Revision 2, Section 3.2.1, which requires each licensee to submit an LER for the completion of any nuclear plant shutdown required by the plant's technical specifications.
The CD EDG was removed from service on January 23, 2003, at 0400 hours0.00463 days <br />0.111 hours <br />6.613757e-4 weeks <br />1.522e-4 months <br /> for planned maintenance and testing.
During the post-maintenance testing, unexpected load fluctuations were experienced with the EDG.
The need for additional troubleshooting prevented completion of the planned maintenance and testing activities within the 72-hour allowed outage time.
CNP is conducting a formal root cause investigation into the EDG governor problem and will supplement this LER upon completion of this effort.
The supplement will report the root cause, corrective actions to prevent recurrence and safety significance of the governor failure.
