==SUBJECT:==
WATERFORD STEAM ELECTRIC STATION, UNIT 3 - INTEGRATED INSPECTION REPORT 05000382/2023003 AND NOTICE OF VIOLATION
 
==Dear Joseph Sullivan:==
On September 30, 2023, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at Waterford Steam Electric Station, Unit 3. On October 16, 2023, the NRC inspectors discussed the results of this inspection with you and other members of your staff.
 
The results of this inspection are documented in the enclosed inspection report.
 
The enclosed report discusses a violation associated with a finding of very low safety significance (Green). The NRC evaluated this violation in accordance with Section 2.3.2 of the NRC Enforcement Policy, which can be found at http://www.nrc.gov/about-nrc/regulatory/enforcement/enforce-pol.html. The violation is cited in Enclosure 1, Notice of Violation (Notice). The violation did not meet the criteria to be treated as a non-cited violation because Entergy Operations, Inc. (licensee) failed to periodically calibrate and process radiation monitors in a timely manner to restore compliance from the previous non-cited violation.
 
Specifically, the licensee failed to ensure that instruments (33 area and radiation monitors) and equipment used for quantitative radiation measurements were calibrated periodically for the radiation measured.
 
You are required to respond to this letter and should follow the instructions specified in the enclosed Notice when preparing your response. If you have additional information that you believe the NRC should consider, you may provide it in your response. The NRCs review of your response will also determine whether further enforcement action is necessary to ensure your compliance with regulatory requirements.

==INSPECTION RESULTS==
Failure to Periodically Calibrate Radiation Monitors Cornerstone          Significance                                Cross-Cutting      Report Aspect              Section Occupational          Green                                        [P.3] -            71124.05 Radiation Safety      NOV 05000382/2023003-01                      Resolution Open The inspectors identified a violation (Green) of 10 CFR 20.1501(c) for failure to periodically calibrate area, process, and effluent radiation monitoring equipment used to perform (e.g.,
dose rate and effluent monitoring) measurements. Specifically, on or around July 2006, the licensee began changing the periodic calibrations of process, effluent, and area radiation monitors without proper technical justification or documented bases.
 
=====Description:=====
As a result of the previous radiation safety inspection conducted in November 2021, the licensee was issued a non-cited violation (NCV) for failure to ensure monitors used for quantitative radiation measurements were calibrated periodically for the radiation measured. The failure to periodically calibrate area, process, and effluent radiation monitors was documented in inspection report 05000382/2021004 as NCV 05000382/2021004-01, Failure to Periodically Calibrate Radiation Monitors, (ADAMS Accession Number ML22028A000). The original violation documented 29 of 41 radiation monitors as being overdue on their required calibration frequencies. This NCV was entered into the licensees corrective action program as condition report CR-WF3-2022-00851.
 
There were two aspects to the prior NCV:
: (1) the changing of the calibration frequencies without technical justification and
: (2) the failure to periodically calibrate the radiation monitors themselves. During the onsite inspection, July 24-28, 2023, the inspectors determined the aspect of changing the calibration frequencies without a technical justification was addressed by the licensee. The licensees Final Safety Analysis Report in chapter 11, section 2.5.2 specified an 18-month calibration frequency for process and effluent monitors. The inspectors reviewed several change requests, dated October 21, 2021, to remove the unjustified extension of the calibration frequencies, specifically the 6.75-year and 9-year frequencies.
 
These change requests were more encompassing and included more than the 41 radiation monitors as described in the prior NCV. The change requests were submitted through the licensees preventive maintenance program which included a work order process to schedule the calibrations at specified frequencies. However, the inspectors determined that the licensee had not periodically calibrated the radiation monitors within their specified frequencies.
 
The NRC Enforcement Policy (Accession Number ML22336A179), section 2.3.2.a described the conditions that allow the NRC to issue NCVs to licensees with credited corrective action programs. Section 2.3.2.a.2 states, in part, that the licensee must restore compliance (or demonstrate objective evidence of plans to restore compliance) within a reasonable period E2-10
 
after a violation has been identified.
 
Since November 2021, the licensee had not demonstrated progress toward restoring compliance by calibrating the overdue radiation monitors. The inspectors determined approximately 68 percent of the 41 radiation monitors were outside their new calibration frequencies. In addition, the information requested by the inspectors showed that only one of the 29 radiation monitors had been calibrated since the previous inspection.
 
During the review of the licensees progress toward restoring compliance, the licensee provided information on the calibration status of 44 area and process radiation monitors not specifically covered by technical specifications, technical requirements manual, or the offsite dose calculation manual. Of the 44 radiation monitors described, 33 were shown as past due for the new calibration frequencies, with three additional radiation monitor calibrations due within two months after the inspection. This information also showed that 20 of the 33 monitors were already beyond the 6.75-year frequency. Of these 20, three exceeded the 9-year frequency and six were simply identified as greater than 8 years.
 
The licensees preventive maintenance program and work order process failed to adequately schedule and complete the radiation monitor calibrations in a timely manner to restore compliance. The prior violation had identified 29 radiation monitors overdue at the time of that inspection. Of the 29 radiation monitors, four were process radiation monitors that required repair prior to calibration. The inspectors observed two of these process radiation monitors not functioning (turned off) during one of the walkdowns (plant tours). In the 20 months since the previous inspection, the calibration of process radiation monitors should have been conducted at least once with an 18-month calibration frequency.
 
Corrective Actions: The prior NCV's corrective action focused on correcting the calibration frequency in the work management process. At the conclusion of the current inspection, the licensee had calibrated only one radiation monitor as identified in the previous NCV within the last 20 months (since November 2021). The licensee has entered this repetitive issue in their corrective action program to create a plan to restore compliance with 10 CFR 20.1501(c).
 
Corrective Action References: CR-WF3-2023-14818
 
=====Performance Assessment:=====
Performance Deficiency: Failure to periodically calibrate area and process radiation monitors in accordance with license commitments and regulatory requirements.
 
Screening: The inspectors determined the performance deficiency was more than minor because it was associated with the Plant Facilities/Equipment and Instrumentation attribute of the Occupational Radiation Safety cornerstone and adversely affected the cornerstone objective to ensure the adequate protection of the worker health and safety from exposure to radiation from radioactive material during routine civilian nuclear reactor operation.
 
Specifically, an ineffective radiation program barrier was identified when radiation monitors were observed to be non-functional (i.e., turned off).
 
Significance: The inspectors assessed the significance of the finding using IMC 0609 Appendix C, Occupational Radiation Safety SDP. The inspectors determined the finding had a very low safety significance (Green) because:
: (1) it was not associated with ALARA planning and work controls,
: (2) it was not an overexposure,
: (3) there was no potential for an overexposure; and
: (4) the ability to assess dose was not compromised.
 
E2-11
 
Cross-Cutting Aspect: P.3 - Resolution: The organization takes effective corrective actions to address issues in a timely manner commensurate with their safety significance. Specifically, the licensee failed to schedule and perform timely calibrations of radiation monitors to restore compliance from a previous NCV documented in CR-WF3-2022-00851.
 
=====Enforcement:=====
Violation: Title 10 CFR 20.1501(c) states, in part, that the licensee shall ensure that instruments and equipment used for quantitative radiation measurements are calibrated periodically for the radiation measured.
 
Contrary to the above, from November 2021 to September 30, 2023, the licensee failed to ensure that instruments (radiation monitors) and equipment used for quantitative radiation measurements were calibrated periodically for the radiation measured. Specifically, the licensee failed to periodically calibrate 33 area and process radiation monitors.
 
Enforcement Action: This violation is being cited because the licensee failed to restore compliance within a reasonable period after the violation was identified consistent with Section 2.3.2 of the Enforcement Policy.
 
Observation:                                                                            71152S The inspectors reviewed the licensees corrective action program to identify performance trends that might indicate the existence of a more significant safety issue The inspectors noted a trend in human performance. Specifically, the inspectors noted six events in which the licensee had repeat issues that significantly impacted plant operations over the last cycle, from May 2022 to October 2023. Examples include:
* CR-WF3-2022-04112: Auxiliary component cooling water pump B failed due to a bearing high temperature on May 8, 2022. The bearing was repaired and failed again on May 23, 2022.
* CR-WF3-2022-05956: Control element assembly 45 caused an alarm in the control room for high voltage on December 9, 2021. The assembly was returned to normal service and the issue repeated on August 18, 2022.
* CR-WF3-2022-06302: Plant protection system power supply 28 tripped on overvoltage on April 1, 2021. The licensee attempted to identify the cause during the subsequent refueling outage. The power supply tripped again on overvoltage on September 6, 2022.
* CR-WF3-2023-15308: One of the two let down pressure control valves failed on August 27, 2023. The licensee identified water in the compressed air line and returned the valve to service. The valve caused another transient on August 31, 2023.
* CR-WF3-2023-15909: Spent fuel pool pump B experienced leakage issues on March 24, 2023. The reworked pump was brought back onsite after 6 months and had similar issues on September 28, 2023.
* CR-WF3-2023-15947: The train B containment fan cooler flow control valve was not providing adequate flow rates on September 19, 2023. The valve was returned to service and exhibited issues again on October 2, 2023.
 
The inspectors did not identify any findings or more-than-minor violations. The licensee identified and performed initial corrective actions as well as follow-up corrective actions for all E2-12
 
these issues. In response to this observation, the licensee documented the trend in CR-WF3-2023-16108.
 
Minor Violation                                                                      71153 Minor Violation Minor Violation: All safety-related radiation monitors were being examined as part of an extent of condition review beginning in January 2022 following identification of incorrect engineering conversion factors for multiple wide range gas monitors. These issues were first described in Licensee Event Report 05000382/2022-001-00, Non-Compliance with Technical Specifications Due to Incorrect Conversion Factors in Three Gaseous Radiation Monitors.
 
These issues were dispositioned by the NRC as a White finding in inspection report 05000382/2022090 (ADAMS Accession Number ML22241A143) and reviewed via a supplemental inspection in accordance with Inspection Procedure 95001 in inspection report 05000382/2023040 (ADAMS Accession Number ML23145A227).
 
On November 16, 2022, as part of the extent of condition review, the licensee identified that three component cooling water radiation monitors had incorrect engineering correction factors. These monitors check for radiation that leaks from connecting systems into the normally clean, closed-circuit CCW system. The correction factors were based on the detectors response to cobalt-60 instead of cesium-137, causing the sensitivity of the detectors to be approximately 46 percent lower than the expected response. The licensee recalibrated the CCW radiation monitors on November 17, 2022. The CCW radiation monitors were found to have been incorrectly calibrated for longer than the allowed outage time in technical specification 3.3.3.1 and therefore required an LER in accordance with 10 CFR 50.73(a)(2)(i)(B). The licensee provided this information to the NRC in LER 05000382/2022-001-02 on February 22, 2023, or about 98 days after identification of the issue. This delay does not meet the requirements of 10 CFR 50.73(a)(1) to submit a Licensee Event Report within 60 days of discovery of the event.
 
Screening: The inspectors determined the violation was minor. The failure to submit a LER in accordance with 10 CFR 50.73 is an example of a Severity Level IV violation in accordance with section 6.9 of the NRC Enforcement Policy. However, the event report was submitted by the licensee before NRC identification and did not impact the ability of the NRC to perform its regulatory oversight function. Therefore, the violation is considered minor in accordance with section 2.2.1 of the NRC Enforcement Policy.
 
=====Enforcement:=====
This failure to comply with 10 CFR 50.73(a)(1) constitutes a minor violation that is not subject to enforcement action in accordance with the NRCs Enforcement Policy. This minor violation, in addition to inspection report 05000382/2023040 (ADAMS Accession No.
 
ML23192A764), closes LER 05000382/2022-001-02.
