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.
If you contest the violation or the significance or severity of the violation documented in this
inspection report, you should provide a response within 30 days of the date of this inspection
report, with the basis for your denial, to the U.S. Nuclear Regulatory Commission, ATTN:
Document Control Desk, Washington, DC 20555-0001; with copies to the Regional
Administrator, Region IV; the Director, Office of Enforcement; and the NRC Resident Inspector
at Waterford Steam Electric Station, Unit 3.

[P.3] -
Resolution
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
E2-11
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.
E2-12
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:
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
E2-13
these issues. In response to this observation, the licensee documented the trend in CR-WF3-
2023-16108.
Minor Violation
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.
