| Title | Licensee-Identified Violation |
| Description | Technical Specification 3.3.12 requires that two channels of boron dilution alarm system shall be operable. Technical Specification 3.3.12 required Actions A.1, B.1, and C.1 are to be performed upon meeting the requirements of the limiting condition for operation. Contrary to the above, between May 8 and May 21, 2008, on multiple occasions, operations personnel did not follow Procedure 40AL-9RK3A, \"Panel B03A Alarm Response Procedure,\" Revision 20, when they failed to reset the boron dilution alarm system alarms and rendered both boron dilution alarm system channels inoperable. The boron dilution alarm system alarms were allowed to remain in fast flash for extended periods and the Technical Specification required actions were not completed. The issue has been entered into the licensees corrective action program as significant CRDR 3178553. The finding is of very low safety significance because it did not contribute to both the likelihood of a reactor trip and the likelihood that mitigation equipment or functions would not be available. |
