SUBJECT:

WATERFORD STEAM ELECTRIC STATION, UNIT 3 - NRC INSPECTION REPORT 05000382/2021013 AND NRC INVESTIGATION REPORT 4-2017-033

Dear Mr. Ferrick:

This letter refers to the investigation completed on September 23, 2020, by the U.S. Nuclear Regulatory Commission (NRC) Office of Investigations at the Waterford Steam Electric Station, Unit 3 (Waterford). The investigation was conducted, in part, to determine if a contract superintendent assigned to Entergy Operations, Inc. (licensee) working at Waterford, willfully directed employees to disengage an equipment protective device and continue drilling into a safety-related concrete structure containing embedded items without first obtaining required engineering evaluation, approval, and documentation, in violation of a quality-related licensee procedure. Enclosure 1 provides a factual summary of the basis for the NRCs concern that willfulness was associated with an apparent violation in this case. The issue was discussed with you and other members of your staff during a telephone conversation February 9, 2021.

Based on the information acquired during the investigation, one apparent violation was identified and is being considered for escalated enforcement action in accordance with the NRC Enforcement Policy. The current Enforcement Policy is included on the NRCs Web site at http://www.nrc.gov/about-nrc/regulatory/enforcement/enforce-pol.html. The apparent violation is against Title 10 of the Code of Federal Regulations (10 CFR) Part 50, Appendix B, Criterion V, which requires, in part, that activities affecting quality shall be prescribed by documented procedures of a type appropriate to the circumstances and shall be accomplished in accordance with these procedures The circumstances surrounding the apparent violation, the potential significance of the issue, and the need for lasting and effective corrective action were discussed with you at the inspection exit meeting on February 9, 2021. Further details regarding this apparent violation are documented in Enclosure 2 to this letter.

Before the NRC makes its enforcement decision, we are providing you an opportunity to:

(1) respond in writing to the apparent violation addressed in this inspection report within 30 days of the date of this letter; or (2) request a predecisional enforcement conference (PEC).

Although the use of alternative dispute resolution (ADR) should normally be offered for cases that fall within the programs scope, the staff may, with the prior approval of the Director, Office of Enforcement, decide not to engage in ADR with a licensee if the issue is of a similar type previously addressed in ADR and the staff believes that an additional ADR is not an effective means to resolve the issue. Therefore, in consultation with the Director, Office of Enforcement ADR will not be offered in this case.

If a PEC is held, the NRC may issue a press release to announce the time and date of the conference; however, the PEC will be closed to public observation since information related to an Office of Investigations report will be discussed and the report has not been made public. If you decide to participate in a PEC, please contact Mr. John Dixon, Chief, Projects Branch D, at 817-200-1574 within 10 days of the date of this letter. A PEC should be held within 30 days of the date of this letter.

If you choose to provide a written response, it should be clearly marked as a Response to An Apparent Violation in NRC Inspection Report 05000382/2021013; EA-20-114 and should include for the apparent violation: (1) the reason for the apparent violation or, if contested, the basis for disputing the apparent violation; (2) the corrective steps that have been taken and the results achieved; (3) the corrective steps that will be taken; and (4) the date when full compliance will be achieved. Your response may reference or include previously docketed correspondence, if the correspondence adequately addresses the required response.

Additionally, your written response should be sent to the U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, DC 20555-0001, with a copy to the Director, Division of Reactor Projects, U.S. Nuclear Regulatory Commission, Region IV, 1600 E. Lamar Blvd., Arlington, TX 76011-4511 and emailed to R4Enforcement@nrc.gov within 30 days of the date of this letter. If an adequate response is not received within the time specified or an extension of time has not been granted by the NRC, the NRC will proceed with its enforcement decision or schedule a PEC.

If you choose to request a PEC, the conference will afford you the opportunity to provide your perspective on these matters and any other information that you believe the NRC should take into consideration before making an enforcement decision. The decision to hold a PEC does not mean that the NRC has determined that a violation has occurred or that enforcement action will be taken. This conference would be conducted to obtain information to assist the NRC in making an enforcement decision. The topics discussed during the conference may include information to determine whether a violation occurred, information to determine the significance of a violation, information related to the identification of a violation, and information related to any corrective actions taken or planned.

In addition, please be advised that the number and characterization of the apparent violation described in the Enclosure 2 may change as a result of further NRC review. You will be advised by separate correspondence of the results of our deliberations on this matter.

In accordance with 10 CFR 2.390 of the NRCs Agency Rules of Practice and Procedure, a copy of this letter, its enclosures, and your responses, if you choose to provide one, will be made available electronically for public inspection in the NRC Public Document Room or from the NRCs ADAMS, accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html. To the extent possible, your response should not include any personal privacy or proprietary information so that it can be made available to the public without redaction. However, you should be aware that all final NRC documents, including the final Office of Investigations report, are official agency records and may be made available to the public under the Freedom of Information Act, subject to redaction of certain information in accordance with the Freedom of Information Act.

If you have any questions concerning this matter, please contact Mr. John Dixon of my staff at 817-200-1574.

Sincerely, Digitally signed by Ryan E.

(1) The inspectors evaluated the circumstances surrounding the inappropriate cutting of structural rebar during a diesel fuel oil storage tank replacement project at the Waterford Steam Electric Station, Unit 3, on November 9 and 10, 2016.

INSPECTION RESULTS Procedure Violation During Fuel Oil Storage Tank (FOST) Replacement Project Cornerstone Significance/Severity Cross-Cutting Report Aspect Section Not Apparent Violation Not 71153 Applicable AV 05000382/2021013-01 Applicable Open EA-20-114 The inspectors identified an apparent violation of 10 CFR 50, Appendix B, Criterion V for the licensees failure to accomplish activities affecting quality in accordance with Procedure PMC-002-003, Rev. 3, Concrete Cutting. Specifically, on November 9 and 10, 2016, a licensee contract superintendent directed employees to disengage an equipment protective device (EPD) and continue drilling into a safety-related concrete structure containing embedded items without the required engineering evaluation, approval, and documentation.

This resulted in the inappropriate cutting of structural rebar in the B1 diesel FOST vault.

Description: On November 9, 2016, as part of the FOST replacement project, contract workers were drilling into the east wall of the Bravo vault. The drilling operation was to support the installation of dowels and anchorage in the concrete walls of the vault for the safety-related diesel FOSTs. Waterford site procedure PMC-002-003, Revision 3, Concrete Cutting, step 10.2.4 required that drills be connected to an EPD, which automatically shuts off power to the drill if it comes into contact with any grounded metal object. The EPD may be eliminated only at the direction of an engineering document that allows the cutting of grounded embedded items and completion of a Job Safety Hazard Analysis (JSHA), in accordance with EN-IS-124, Revision 4. Manual EN-IS-124, Revision 4, which is incorporated by reference to Procedure PMC-002-003, requires, in part, that if the EPD trips, Engineering shall be engaged in the identification of the object that was contacted and must approve in writing the continued drilling without use of the EPD.

During the November 9, 2016 drilling operations, the contract workers were using the EPD and stopped drilling when the EPD disengaged the drill after hitting an obstruction, in accordance with site procedures. The workers informed the foreman on duty that they had hit an obstruction, and the foreman took the information to the superintendent. The superintendent provided the foreman with a rebar eater drill bit, which was kept in a locked storage box in his office and instructed the workers to continue drilling through the obstruction.

On November 10, 2016, a contract worker began drilling in the bravo vault with the rebar cutting bit with the direction to cut through inconsequential metal embedded in the concrete.

The worker shined a flashlight in the hole and saw what appeared to be a piece of rebar. The worker immediately stopped and notified the foreman that he had cut through rebar. The foreman then notified the superintendent that had provided the rebar eater drill bit. Shortly thereafter, the superintendent went to the vault and examined the hole. The daily construction report for November 10, 2016, signed by the superintendent, documented in the work completed section, Working the East wall having issues. Need to cut rebar and documented in the probable future delay section, Its slow cutting thru the rebar.

On November 14, 2016, the field engineer received a call from the Bravo vault to examine an obstruction. He in turn called civil engineer, who confirmed that the obstruction was structural rebar. During the NRCs subsequent review of this issue, the civil engineer confirmed that he would not have approved cutting through rebar. The superintendent did not obtain the required engineering evaluation, approval, and documentation authorizing the drilling through the rebar.

Corrective Actions: The licensee evaluated the cut rebar and the associated structure for functionality, established additional controls in the form of a rebar eater drill bit checkout and log sheet, and performed a stand-down with the contract workers to reinforce the requirements of the procedure.

Corrective Action References: Condition Report CR-WF3-2016-07183 Performance Assessment: The Reactor Oversight Process does not specifically consider willfulness in its assessment of licensee performance. Therefore, it is necessary to address this violation which involves willfulness using the traditional enforcement process.

Enforcement: The severity of this apparent violation will be determined in accordance with the Enforcement Policy pending a final enforcement determination.

Apparent Violation: Title 10 CFR Part 50, Appendix B, Criterion V, requires, in part, that activities affecting quality shall be prescribed by documented procedures of a type appropriate to the circumstances and shall be accomplished in accordance with these procedures.

Licensee Procedure PMC-002-003, Concrete Cutting, Revision 3, step 10.2.4 requires, in part, that drills be connected to an EPD. The EPD may be eliminated only at the direction of an engineering document that allows the cutting of grounded embedded items and completion of a Job Safety Hazard Analysis, in accordance with EN-IS-124, Industrial Safety Planning & Job Safety Hazards Analysis, Revision 4. Manual EN-IS-124, Revision 4, which is incorporated by reference to Procedure PMC-002-003, requires, in part, that if the EPD trips, Engineering shall be engaged in the identification of the object that was contacted and must approve in writing the continued drilling without use of the EPD.

Contrary to the above, on November 9 and 10, 2016, licensee contract employees performed concrete drilling, an activity affecting quality, and failed to connect the drill to an EPD and did not have an engineering document that allowed the cutting of grounded embedded items with the EPD disconnected. Specifically, during concrete drilling in the safety-related B1 FOST vault cubicle, workers disengaged an EPD and continued drilling into a structure containing embedded items without the required engineering documentation. This resulted in the cutting of structural rebar without an engineering evaluation.

Enforcement Action: This violation is being treated as an apparent violation pending a final significance (enforcement) determination.

EXIT MEETINGS AND DEBRIEFS The inspectors verified no proprietary information was retained or documented in this report.

On February 9, 2021, the inspectors presented the NRC inspection results to Mr. J. Ferrick, Site Vice President, and other members of the licensee staff in a telephonic exit meeting.
