| ENS 52502 | 20 January 2017 16:01:00 | The following is an excerpt of a part 21 received via email: The purpose of this letter is to provide the NRC an interim report in general conformity to the requirements of 10CFR Part 21.21 (a)(2). During an internal audit in November 2016, the sampling plan for dedication of plastic jars used in 1E battery cells was reviewed. Two lot numbers are associated with each plastic jar, a material lot number and a molding number. A material lot may encompass several molding lots. The dedication sampling plan was based on the material lot, and may not have properly sampled variations in critical characteristics generated by molding lots. An analysis of historical data is underway to determine whether any deviations to specifications for critical characteristics may have occurred, and whether these possible deviations could represent a defect as defined by Part 21. C&D expects that this analysis will be completed by March 20, 2017.
