| Title | Licensee-Identified Violation |
| Description | Unit 1 SR 4.7.3.b requires in part that at least once per 18 months, each CCS pump start automatically on a SIS signal. Contrary to the above, the C-S (swing) CCS pump was never tested to automatically start using a Unit 1 SIS signal. The licensee considered this to be a never performed surveillance rather than simply a missed surveillance since no testing records since initial operation in 1980 could be located. The pump had been successfully tested every 18 months from the Unit 2 SIS as this pump is normally powered from Unit 2. As an alternate and abnormal lineup, the pump could be powered from Unit 1 and thus the requirement for start testing using the Unit 1 SIS. This finding was considered more than minor because it was associated with the mitigating system cornerstone and affected the cornerstones reliability due to the failure to fully test the CS CCS pump for over 30 years. The finding was considered of very low safety significance as it remained operable and available during the affected period due to successfully passing the initial surveillance test performed on January 13, 2014. The issue was entered into the CAP as PER 826482. Note that this issue is also discussed under Section 4OA3 of this report as it involved a LER. |
