SUBJECT:

PILGRIM NUCLEAR POWER STATION - NRC INVESTIGATION REPORT NO.

1-2017-015

Dear Mr. Sullivan:

This letter refers to an investigation by the U.S. Nuclear Regulatory Commission (NRC) Office of Investigations (OI) conducted at Entergy Nuclear Operations, Inc.s (Entergys) Pilgrim Nuclear Power Station (Pilgrim). The investigation, which was completed on September 27, 2017, was conducted to determine whether an Entergy Instruments & Controls (I&C) supervisor at Pilgrim caused Entergy to violate NRC requirements related to work management by denoting a work order as Complete in the sites work management system before the activity was completed.

As described below, the NRC determined that the circumstances of the case did not result in a violation of NRC requirements.

On March 27, 2017, during a scheduled work window on the Reactor Core Isolation Cooling (RCIC) system, Pilgrim staff scheduled several RCIC surveillance tests, including the biennial high water level test. As identified during the investigation, the I&C supervisor changed the status of the high water level test work order to Complete at approximately 2:54 PM. Entergys work management procedure describes that moving a work order to Complete status means that all tasks are finished and applicable paperwork has also been signed off. The supervisor informed OI that he changed the work order status after being told by technicians who had been performing the test that the lead technician was in the process of getting the paperwork signed off. However, OI identified that, although all plant manipulations for the test were complete, the lead technician was still performing the final steps in the procedure, and did not complete these until approximately 3:30 PM.

The NRC determined that denoting the work order as Complete did not have any impact on plant equipment or operating status. Specifically, the remaining steps were administrative in nature, and denoting the work order as Complete did not affect their performance or result in the performance of subsequent work activities that should not have been performed at that time.

The NRC considered that the work management system is a work scheduling tool that also serves as the electronic repository for scanned copies of completed work procedures and other documents. In light of the above and based on the evidence gathered during the OI investigation, the NRC concluded that the circumstances of the case did not result in a violation of NRC requirements. Therefore, the NRC is not taking any enforcement action against Entergy.
