General when the licensee did not make surveys to assure compliance with 10 CFR 20.1802 Control of material not in storage. Specifically, the licensee failed to perform an adequate survey of a worker who alarmed a portal monitor at the facility exit, resulting in the uncontrolled release of radioactive material to unrestricted areas.

Additional Tracking Items

None.

PLANT STATUS

The plant began the inspection period at 97 percent power due to ongoing "A" flow control valve position fluctuations without operator demand experienced during the previous reporting period.

On April 2, 2022, the unit again experienced an undemanded movement of the "A" flow control valve following restoration from troubleshooting efforts which required operators to reduce reactor power to approximately 88 percent in order to restore recirculation loop flows to required band. The plant was restored to near full power operations on April 6, 2022, following repair and modification activities to the "A" flow control valve control circuitry. The unit remained at or near 100 percent power for the remainder of the inspection period except for rod sequence exchanges, required testing, and in some instances power reductions to maintain condensate demineralizer outlet temperature and/or condenser circulating water outlet temperature at or below their respective upper limits due to environmental conditions. The power reductions varied between 1 to 12 percent of rated thermal power and lasted from a few hours to several days.

INSPECTION SCOPES

Inspections were conducted using the appropriate portions of the inspection procedures (IPs) in effect at the beginning of the inspection unless otherwise noted. Currently approved IPs with their attached revision histories are located on the public website at http://www.nrc.gov/reading-rm/doc-collections/insp-manual/inspection-procedure/index.html. Samples were declared complete when the IP requirements most appropriate to the inspection activity were met consistent with Inspection Manual Chapter (IMC) 2515, Light-Water Reactor Inspection Program - Operations Phase. The inspectors performed activities described in IMC 2515, Appendix D, Plant Status, observed risk-significant activities, and completed on-site portions of IPs.

INSPECTION RESULTS

Failure to Survey Annulus during Moisture Separator Move Cornerstone Significance Cross-Cutting Report Aspect Section Occupational Green [H.13] - 71124.01 Radiation Safety NCV 05000440/2022002-01 Consistent Open/Closed Process The inspectors reviewed a self-revealed Green finding and associated non-cited violation (NCV) of 10 CFR 20.1501 when the licensee failed to perform adequate surveys to demonstrate compliance with High Radiation Area (HRA) posting and controls required by 10 CFR 20.1902 and 20.1601 during moisture separator lifts.

Description:

This facility has a cylindrical containment building which includes a refuel floor, where reactor disassembly and reassembly occurs. During disassembly, the reactors moisture separator, a highly contaminated piece of equipment, is lifted from the center of the refuel pool via a crane, moved to the north side of the pool, and lowered back into the pool. While the component is in the pool, substantial radiation shielding is provided by the water in the pool.

However, when the component is lifted from the pool, dose rates on the refuel floor become elevated. The containment is also surrounded by another cylindrical structure called the annulus. At elevations below the refuel floor there is substantial shielding, in the form of concrete and water, between radioactive components inside containment and the annulus.

However, at elevations at and above the refuel floor, the shielding provided is reduced to a steel liner ranging from 1 to 3 inches in thickness, which provides significantly less radiation shielding.

On March 11, 2021, two individuals, who were working in the annulus at about the same elevation as the refuel floor, received dose rate alarms on their electronic alarming dosimeters (EADs). These individuals placed their work in a safe condition, left the area and reported to Radiation Protection (RP). Maximum dose rates seen on the individuals EADs were 224 mrem/hr and 366 mrem/hr, with alarm setpoints of 75 mrem/hr. RP entered the annulus, which was posted and controlled as a radiation area, to perform follow-up surveys.

These surveys indicated dose rates of approximately 2 mrem/hr where the individuals were working. However, RP determined that at the time of the EAD alarms, the moisture separator lift was occurring inside containment and that the lift had been completed prior to RP entering the annulus to perform the EAD alarm follow-up surveys. Instead of performing a radiation survey prior to the moisture separator removal, the licensee relied on historical practices to determine the radiological controls, resulting in the area being posted and controlled as a radiation area.

Since RP could not validate the dose rates via follow-up surveys, they performed an evaluation using a software program that can model dose rates at various locations in relation to a radiation source. This evaluation utilized dose rates seen along the refuel pool railing during the moisture separator lift to estimate the dose rates inside the annulus. The dose rates seen along the refuel pool railing ranged from approximately 1.2 Rem/hr along the south railing (furthest from the moisture separator) to approximately 82 Rem/hr along the north railing (closest to the moisture separator). The licensees evaluation estimated radiation levels of approximately 400 mrem/hr in the location of the workers, which generally aligned with the dose rates seen on the EADs. Additionally, during the moisture separator move for reactor reassembly, the licensee posted and controlled accessible areas of the annulus at and above the refuel floor as HRAs and performed dose rate measurements at five locations. The maximum dose rate seen was approximately 350 mrem/hr at 1 foot from the steel liner.

The inspectors determined there were technical issues with the licensees evaluation. For example, the analysis performed via the software program had an error in which measurements that should have been in feet were entered as centimeters. Additionally, neither the analysis performed via the software program, nor the surveys conducted in the annulus during reassembly, established dose rates in accessible areas that would be expected to receive the highest dose rates during the moisture separator move. Specifically, the software program evaluation only looked at the location where the individuals who received the EAD dose rate alarms were, which was on the west-northwest side of containment. Additionally, although the surveys taken during reassembly were done at five different locations, none of the surveys were performed at the accessible locations closest to the north side of containment (the accessible areas closest to the moisture separator).

Irrespective of these issues, the inspectors determined that the areas within the annulus met the conditions requiring HRA postings and controls at the time of the moisture separator lift on March 11, 2021, during disassembly.

Corrective Actions: The licensee entered the issue into the corrective action program.

Corrective actions taken included updated procedure HPI-C0018, "Radiation Protection Response to Changing Plant Conditions, to include posting and controlling these accessible areas in the annulus as HRAs prior to commencing movement of various highly radioactive equipment in containment, as well as posting and controlling the annulus based on dose rates seen along the containment wall from the refuel floor. The licensee also plans to complete additional surveys of the annulus during the next moisture separator move to ensure that accessible areas expected to see the highest dose rates are surveyed.

Corrective Action References: CR-2021-01739, Two Unbriefed Dose Rate Alarms Received in Containment Annulus

Performance Assessment:

Performance Deficiency: The licensee failed to perform radiological surveys, as required by 10 CFR 20.1501, in the annulus to evaluate the impact from moisture separator lifts on the refuel floor in containment.

Screening: The inspectors determined the performance deficiency was more than minor because it was associated with the Program & Process 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, the failure to survey resulted in inadequate controls for an HRA, which could lead to unintended dose to workers. The performance deficiency is similar to example 6F in IMC 0612 Appendix E, Examples of Minor Issues.

Significance: The inspectors assessed the significance of the finding using IMC 0609 Appendix C, Occupational Radiation Safety SDP. Specifically, the inspectors determined that this finding is of very low safety significance (Green) because the performance deficiency was not related to ALARA [as low as reasonably achievable], did not result in an overexposure nor a substantial potential for an overexposure, and the ability to assess dose was not compromised.

Cross-Cutting Aspect: H.13 - Consistent Process: Individuals use a consistent, systematic approach to make decisions. Risk insights are incorporated as appropriate. Specifically, the licensee did not incorporate risk insights into a systematic approach in evaluating radiologically significant components in accessible areas adjacent to the area the components are in.

Enforcement:

Violation: Title 10 CFR 20.1501 requires that the licensee make or cause to be made surveys that may be necessary for the licensee to comply with the regulations in 10 CFR Part 20 and that are reasonable under the circumstances to evaluate the magnitude and extent of radiation levels. 10 CFR 20.1601 requires specific controls associated with HRA access and 10 CFR 20.1902 requires specific postings for HRAs.

Pursuant to 10 CFR 20.1003, survey means an evaluation of the radiological conditions and potential hazards incident to the production, use, transfer, release, disposal, or presence of radioactive material or other sources of radiation. When appropriate, such an evaluation includes a physical survey of the location of radioactive material and measurements or calculations of levels of radiation, or concentrations or quantities of radioactive material present.

Contrary to the above, on March 11, 2021, the licensee failed to perform surveys in accordance with 20.1501 to demonstrate compliance with 20.1601 and 20.1902. Specifically, the licensee did not conduct radiological surveys to evaluate the radiation levels in the annulus for the movement of the moisture separator inside containment to ensure that HRA postings and controls were implemented based on radiation levels.

Enforcement Action: This violation is being treated as a non-cited violation, consistent with Section 2.3.2 of the Enforcement Policy.

Failure to Survey Worker After Alarming a Portal Monitor Cornerstone Significance Cross-Cutting Report Aspect Section Public Radiation Green [H.8] - 71124.04 Safety NCV 05000440/2022002-02 Procedure Open/Closed Adherence The inspectors reviewed a self-revealed finding of very low safety significance (Green) and an associated NCV of 10 CFR 20.1501 (a)(1) Surveys and Monitoring, General when the licensee did not make surveys to assure compliance with 10 CFR 20.1802 Control of material not in storage. Specifically, the licensee failed to perform an adequate survey of a worker who alarmed a portal monitor at the facility exit, resulting in the uncontrolled release of radioactive material to unrestricted areas.

Description:

On April 2, 2021, a decontamination technician completed their night shift work on the refuel floor during the Perry Nuclear Power Plant 1R18 refueling outage, which was the workers last day of work at the Perry site. The worker exited the site at the Primary Access Facility.

The worker entered a portal-style radiation monitor as part of the exit process and received an alarm. The worker indicated (in a subsequent statement/interview) that they then contacted a member of the RP staff to get support based upon the radiation alarms. Based upon this conversation with RP staff, the workers understanding was that they were to continue to monitor (while removing articles of clothing to determine where the contamination might be present) until RP responded to the area. After several more attempts, the worker exited the portal monitor and proceeded to call RP stating they had successfully passed the monitor and that no additional support was needed. The licensee's procedures require workers to contact RP after two monitor alarms. Additionally, licensee procedure instructs RP technicians to perform radiological surveys of individuals who alarm portal monitors twice.

Subsequently, neither of these procedural requirements were met when the worker exited the facility.

On April 5, 2021, the worker arrived at another nuclear reactor facility where they alarmed the portal monitor during in-processing activities. The other nuclear reactor facility performed radiological surveys that identified both internal and external contamination of the worker.

During decontamination activities, a discrete radioactive particle was identified with an activity of 80,000 disintegrations per minute. Additionally, low level contamination of clothing and shoes was identified. Once external decontamination efforts were completed, in-vivo bioassay was completed via a whole-body counter. The Radiation Protection Manager (RPM) of the other nuclear reactor facility contacted the RPM at Perry to inform them of the potential issue.

Perry Nuclear Power Plant performed a review of video footage that revealed the multiple portal monitor alarms by the worker on the morning of April 2, 2021. The video footage also appeared to show the worker moving off-camera and making attempts to contact the Perry RP staff for assistance (via a telephone in the immediate area). At no time during the 30 minutes did a member of the RP staff arrive to survey the worker. The licensee assessed the information (both onsite and from the other nuclear reactor facility) and determined that the dose to the individual was likely less than 5 mrem to the individuals whole body.

Corrective Actions: The radioactive material found on the worker was confiscated and returned to Perry Nuclear Power Plant for disposal. Additional radiological surveys were performed at the workers hotel. Training was conducted for onsite RP technicians and contractor RP technicians on portal monitor alarm responsiveness and radiological risk awareness.

Corrective Action References: CR-2021-02636

Performance Assessment:

Performance Deficiency: The licensee failed to perform adequate surveys to control licensed material within the facility. Specifically, the licensee did not perform required radiological surveys of a worker who alarmed the portal monitors. Subsequently, the failure to perform required surveys resulted in the uncontrolled release of radioactive material into unrestricted areas.

Screening: The inspectors determined the performance deficiency was more than minor because it was associated with the Program & Process attribute of the Public Radiation Safety cornerstone and adversely affected the cornerstone objective to ensure adequate protection of public health and safety from exposure to radioactive materials released into the public domain as a result of routine civilian nuclear reactor operation. Specifically, the licensee did not perform radiological surveys of a worker who alarmed a portal monitor which resulted in an uncontrolled release of the radioactive material into unrestricted areas.

Significance: The inspectors assessed the significance of the finding using IMC 0609 Appendix D, Public Radiation Safety SDP. The inspectors determined that the finding was of very low safety significance (Green) because there was an uncontrolled release of radioactive material into unrestricted areas that resulted in dose to the public below 0.005 rem Total Effective Dose Equivalent.

Cross-Cutting Aspect: H.8 - Procedure Adherence: Individuals follow processes, procedures, and work instructions. Specifically, RP staff did not follow their procedures and processes to respond to a portal monitor alarm.

Enforcement:

Violation: Title 10 CFR 20.1501 requires, in part, that each licensee make or cause to be made surveys that may be necessary for the licensee to comply with the regulations in Part 20 and that are reasonable under the circumstances to evaluate the extent of radiation levels, concentrations or quantities of radioactive materials, and the potential radiological hazards that could be present.

Pursuant to 10 CFR 20.1003, survey means an evaluation of the radiological conditions and potential hazards incident to the production, use, transfer, release, disposal, or presence of radioactive material or other sources of radiation. When appropriate, such an evaluation includes a physical survey of the location of radioactive material and measurements or calculations of levels of radiation, or concentrations or quantities of radioactive material present.

Title 10 CFR 20.1802, requires, in part, that the licensee control and maintain constant surveillance of licensed material that is in a controlled area or unrestricted areas and that is not in storage.

Contrary to the above, on April 2, 2021, the licensee failed to perform surveys to assure compliance with 10 CFR 20.1802. Specifically, on April 2, 2021, the licensees survey of a worker who alarmed the portal monitor did not control licensed material from inadvertently being carried outside of the controlled area and restricted areas of the site. A discrete radioactive particle of 80,000 disintegrations per minute was carried offsite by the worker.

Enforcement Action: This violation is being treated as a non-cited violation, consistent with Section 2.3.2 of the Enforcement Policy.
