Title | Historical Condition Previously Reported in Ler 2009-003 Should Also Have Been Reported in Accordance with 10 Cfr 50.72 (B)(3)(V)(D) |
Event Description | On October 7, 2009, two independent diesel generators were rendered inoperable. This was reported in LER 2009-003 as a condition prohibited by plant technical specifications and a common cause that resulted in two independent trains becoming inoperable.
Upon further review, the condition which existed at Millstone Power Station Unit 2 and reported to the NRC in LER 2009-003, should also have been reported per the requirements of 10CFR50.72(b)(3)(v)(D). A supplement to LER 2009-003 will be submitted. The NRC Resident Inspector has been notified. |
