Title | Licensee-Identified Violation |
Description | TS LCO action statement 3.6.2.2.a requires that with the spray additive system inoperable, action shall be taken to restore the system to operable status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />, or be in at least hot standby within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />. Contrary to the above, on June 22, 2015, PSEG determined that the spray additive system was inoperable for a period of time greater than allowed by TS. Specifically, PSEG review of past CS additive tank level versus estimated NaOH concentration by weight indicated that the NaOH concentration in the tank had decreased below the TS limit of 30 percent by weight on January 15, 2015, based on dilution from in-leakage. On June 23, 2015, following chemical addition, NaOH concentration was verified to be 31.4 percent by weight NaOH, and Salem Unit 1 exited TS action statement 3.6.2.2.a. PSEG reported this event as an LER, as documented in Section 4OA3 of this report. The inspectors determined that the finding was of very low safety significance (Green) in accordance with Section A of Exhibit 2 in Appendix A of IMC 0609, "The Significance Determination Process for Findings at Power, because PSEG determined under ACE 70178077 that design calculations confirmed the spray additive system will perform its safety function within the range of 28 to 36 percent by weight NaOH solution. Because this finding is of very low safety significance and has been entered into PSEG's CAP under NOTF 20694465, this violation is being treated as a Green NCV consistent with the NRC Enforcement Policy. |
