Entergy Operations, Inc. (EA-20-114) (Waterford Steam Electric Station, Unit 3)

On May 18, 2021, the NRC issued a Severity Level III Notice of Violation to Entergy Operations, Inc. (Licensee), for a violation of 10 CFR 50, Appendix B, Criterion V at Waterford Steam Electric Station, Unit 3. Specifically, licensee contract employees at the direction of their superintendent disconnected an equipment protective device and drilled through embedded structural steel reinforcing bar in a safety-related wall without first obtaining the required approval.

Turkey Point Nuclear Generating Station, Unit Nos. 3 and 4 (EA-20-043 | EA-20-150)

On April 6, 2021, the NRC issued a Notice of Violation and Proposed Imposition of a Civil Penalty in the amount of $150,000 to the Florida Power & Light Company for a Severity Level III problem at Turkey Point Nuclear Generating Station.  The enforcement action is the result of two separate investigations completed by the NRC’s Office of Investigations.  The first investigation determined that three mechanics willfully falsified the inspection and maintenance of a safety-related check valve in the auxiliary feedwater system.  This event occurred in January 2019.  The second investigation determined that two technicians, a supervisor and a manager, willfully failed to inform control room staff that maintenance had been performed on the wrong unit’s Chemical and Volume Control System charging pump.  This second event occurred in July 2019.  As a result of these two investigations, the staff identified two violations of 10 CFR 50.9(a), “Completeness and Accuracy of Information,” and a violation of 10 CFR 50, Appendix B, Criterion XVII, “Quality Assurance Records.”  

Purdue University (Purdue University Research Reactor) (EA-20-144)

On February 16, 2021, the NRC issued a Notice of Violation to Purdue University for a Severity Level III problem involving two violations.  The first violation involves the Purdue University Research Reactor operating at steady state power levels in excess of 12 kilowatts (thermal) on several occasions between October 31, 2019, and September 15, 2020, contrary to Purdue University Research Reactor License Condition 2.C.1.  Specifically, the reactor was inadvertently operated at power levels greater than 12 kW(t) during this time due to nuclear instrument (NI) calibration calculation errors that caused the NIs to indicate reactor power levels that were approximately three times lower than actual reactor power. Therefore, when the licensee operated the reactor above 4 kW(t) (indicated power) several times between October 31, 2019, and September 15, 2020, the actual reactor power exceeded the maximum authorized power level of 12 kW(t).  The second violation involves Purdue University’s failure to perform appropriate surveillance testing before considering the NI system operable following replacement of the NI system and detectors in 2019, contrary to Purdue University Research Reactor Technical Specification 4.2.g.
