The follow is a summary of the Part 21 rep … The follow is a summary of the Part 21 report that was received via fax:</br>Engine Systems Inc. (ESI) began a 10CFR21 evaluation on November 12, 2016, following the seizure of a fuel injector at Entergy Operations Inc. - Arkansas Nuclear One (ANO). ANO had completed installation of new fuel injectors on both of their EMD emergency diesel generator sets. During post-maintenance surveillance testing the fuel injector installed in the #7 cylinder of unit K4A seized (injector S/N 16C2 3186). During an attempt to shut down the unit, operators were unable to reduce the engine's load because of the seized injector/fuel rack.</br>The seized fuel injector was then returned to ESI for failure analysis where it was received on November 16. The failure investigation determined that foreign material within the injector was the cause of the seizure. The report (8002768-FA) was completed on December 8, 2016, and submitted to the customer for review.</br>The root cause of the failure was determined to be foreign material which likely entered the fuel injector during manufacture/assembly. Once the injector was installed on the engine, it was during engine surveillance (run) testing that this foreign material migrated into the plunger and bushing assembly. This decreased the running clearance between the components which ultimately lead to seizure.</br>Component: EMD Fuel Injector, Part Number 40084720.</br>Entergy Operations Inc.- Arkansas Nuclear One is the only customer to whom ESI has supplied suspect fuel Injectors.m ESI has supplied suspect fuel Injectors. +
