| Title | Licensee-Identified Violation |
| Description | Technical Specification LCO 3.0.2 requires that Upon discovery of a failure to meet an LCO, the Required Actions of the associated Conditions shall be met, except as provided in LCO 3.0.5 and LCO 3.0.6. Technical Specification LCO 3.3.3 requires that two channels of containment sump water level wide range PAM instrumentation be operable. Contrary to the above, during a channel check on June 26, 2014, at approximately 07:30 a.m., the Unit 1 shift supervisor failed to enter the required action statement for TS LCO 3.3.3, Condition B when one Unit 1 containment sump water level wide range channel was noted to be failed high. Inoperability of the transmitter was not recognized until July 9, 2014 during a control board walk down, and the LCO was entered at 5:00 p.m. Upon investigation, it was determined that the channel was indicating incorrectly on June 23, 2014, prior to the channel check. The licensee documented this event in their corrective actions program as CRs 837302 and 837838. Using IMC 0609 Phase 1 Initial Screening and Characterization of Findings, the finding was determined to affect the mitigation systems cornerstone because of the effect on long term core decay heat removal in the event of a LOCA. Because this was a single failure that did not represent an actual loss of safety system or function, the operability of the additional channel, among other indications, would have been sufficient to inform operators of an accident condition, and the inspectors determined this to be a Green finding of very low safety significance. |
