| Title | Interim Part 21 Report - Inability to Complete Evaluation Regarding Cracking in Kcr-13 Standby Battery Jars |
| Event Description | The following was received via email:
The purpose of this letter is to provide the NRC a report in general conformity to the requirements of 10 CFR Part 21.21(a)(2). On March 4, 2015, C&D Technologies, Inc. (C&D) was informed by Entergy Nuclear Northeast that a KCR-13 battery installed at the Indian Point Nuclear Energy Center had developed a crack in the polycarbonate jar material. This is the second KCR-13 at this site that has experienced a crack in the jar material [see EN 49667]. The jar is a safety related component with the primary function of containing electrolyte. The battery has not been returned to C&D for analysis, and analysis of the previous issue was inconclusive. C&D is submitting this interim report to the NRC and notifying C&D's customers that use C&D KCR-13 batteries, of this Interim report, and is initiating an action plan to evaluate the reported potential defect and determine whether it could pose a substantial safety hazard for any US licensee using such batteries. KCR-13 Batteries manufactured in 2005, battery manufacturing date is on the label. Note: C&D has not completed its evaluation of the reported potential defect and whether it could pose a substantial safety hazard at any US licensee using such batteries. The cracked jar has not been fully evaluated and may or may not indicate a potential defect which could create a substantial safety hazard. KCR -13 batteries used at Nuclear Plants in 1E applications made in 2005: Utility/Plant Name/Battery Model/Quantity of Batteries Entergy/Indian Point /KCR-13 NUC/72 Xcel Energy/Monticello/KCR-13 NUC/62 Concurrent Actions underway to complete the evaluation: a) On receipt of the battery from Indian Point, C&D will perform a failure analysis with the intent of determining the root cause of the cracking issue. Maximum time 30 days from receipt of the battery. b) In conjunction with the licensees identified in Section VI, C&D will recommend maintenance assessment of all KCR-13 batteries at these locations to determine their status and specifically, the presence of any evidence of potential defects via visual examination. For any cells exhibiting the presence of potential defect, C&D shall further recommend that they be returned for analysis. Estimated completion date of analysis is thirty (30) days from the receipt of the returned batteries. U.S. Licensees using batteries possibility containing the alleged defect have been notified of the filing of this interim report with recommendations that they examine their batteries for any signs of problems. NOTE: A similar notification and advice was provided in December 2013 with the previous battery. C&D did not receive any reports of similar problems from other product users. If you have any questions or wish to discuss this matter or this report, please contact: Robert Malley VP Operational Excellence bmalley@cdtechno.com (215) 619-7830 The similar notification and advice provided in December 2013 is EN 49667.
The following information was received from C&D Technologies via email: Subject: Retraction of Interim Report - Inability to Complete 10CFR Part 21 Evaluation Regarding Cracking in KCR-13 Standby Battery Jars On May 29, 2015 C&D Technologies submitted an interim Part 21 report (ML15155A575, Part 21 log 2015-34-00) regarding jar cracks discovered in a KCR-13 battery at Indian Point Nuclear Energy Center. This report was issued as the analysis of this battery jar had not yet been completed. The analysis was subsequently completed, and it was determined that the jar cracking was not related to the design or production of this battery, and thus is not a defect reportable under Part 21. Indian Point Nuclear Energy Center was notified of the findings of the report; however, no final Part 21 report was issued by C&D to the NRC, leaving the interim Part 21 report open. Based on the results of the analysis the Interim Report (NRC Log No. 2015-34-06) dated May 29, 2015 is retracted. Notified R1DO (McKinley), R3DO (Stone) and Part 21/50.55 Reactors via email. |
