Finding

Title

Licensee-Identified Violation

Description

10 CFR 50, Appendix B, Criterion III, Design Control, requires, in part, that measures shall be established to assure that applicable regulatory requirements and the design basis, are correctly translated into specifications, drawings, procedures, and instructions. Contrary to the above, NextEra did not assure that the design basis for safety-related service water piping installed per design change record 93DCR003 was correctly translated into procedures and instructions. Specifically, when implementing design change 93DCR003, NextEra did not establish a requirement in plant procedures to track the service life of the plastisol liner or establish measures during preventive maintenance activities to assure the material remained bonded to the pipe. The plastisol liner material was found delaminated and generating foreign material in the service water pipe providing cooling water to the B emergency diesel generator on October 10, 2011. This was identified in the corrective action program as Condition Report 1694951 to initiate review of the service water monitoring program, revise the design change process and take other long-term corrective actions. This finding is of very low safety significance (Green) because it did not represent an actual loss of safety function or contribute to external event core damage sequences.
