| Title | Part 21 Interim Report of Deviation |
| Event Description | Meggitt Safety Systems, Inc. (Meggitt) has recently identified situations where the appropriate amount of testing was not performed to verify the acceptability of critical characteristics for commercially procured materials for use in safety related products in the Nuclear Cable Product Line. On February 5, 2021 during an internal audit, it was discovered that material verification for critical characteristics for several components had not been performed in accordance with Meggitt Engineering Document (ER94113 Rev T). These components are used on Meggitt nuclear safety related cables for in-containment instrumentation and control cables. These are also used on fire-resistant (Appendix R) power and control cables. The safety function of the in-containment and Appendix R cables is to reliably interconnect the detection/sensing device to the plant instrumentation during normal and [Loss of Coolant Accident] LOCA conditions and to interconnect the remote control location to critical devices during normal and abnormal/fire conditions respectively. Without the material verification there is a potential that the cables would not perform their Safety function properly.
Meggitt is revalidating materials and engaging suppliers to satisfy critical characteristics verification requirements. Meggitt's preliminary assessment is that there is no impact to the safety function, however the COVID-19 pandemic has impacted our ability to complete our investigation. As a result, Meggitt is unable to meet the 60 day requirement and requests an additional 60 days to complete the Part 21 Safety Evaluation. The expected completion date is June 4, 2021. Contact Information: Jim Healy Senior Vice-President and General Manager Meggitt Safety Systems, Inc. 1785 Voyager Ave Simi Valley, CA 93063 (805) 581-8608
Meggitt's evaluation has been concluded with satisfactory results. There is no safety hazard on delivered nuclear cables as a result of inadequate constituent component material verification, nor does the failure to comply potentially cause a substantial safety hazard. These conditions are not reportable under Meggitt Airframe Systems procedure SOP 6045 and regulation 10CFR Part 21 and 10 CFR 50.55(e). Notified R1DO (Bickett), R2DO (Miller), R3DO (Dickson), R4DO (Groom), and Part 21 Reactors Group (by email). |
