Licensee-Identified Violation

Description

Unit 3 Technical Specification 3.3.8.1, AC Sources - Operating, required EDGs to be operable in Modes 1, 2, and 3, and with multiple EDGs inoperable, required all but on EDG be returned to service in 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months or be in Mode 3 within 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months and in Mode 4 within 36 hours4.166667e-4 days 0.01 hours 5.952381e-5 weeks 1.3698e-5 months . Contrary to this, between December 22, 2012, and January 9, 2013, the licensee determined that multiple EDGs were inoperable as a result of failed 3D EDG and degraded 3A and 3B EDG generator blower bearings. This TS violation was entered into the licensees CAP as PERs 665217, 675339, and 675952. This finding represented an actual loss of function of the 3D EDG for greater than the TS allowed outage time, and therefore, required a detailed risk evaluation. Because of the short exposure time related to the performance deficiency, the finding was determined to be of very low safety significance (Green).
