3. Health Physics a.
Inspection Scope (IP 69001, Section 2.07)
To verify compliance with 10 CFR Part 19, Notices, Instructions and Reports to Workers: Inspection and Investigations, 10 CFR Part 20, Standards for Protection against Radiation, and TS sections 3.7, Radiation Monitoring, 4.7, Radiation Monitoring, and 6.3, Radiation Safety, the inspector reviewed selected aspects of:
dosimetry records from 2021 to the present
radiation training records and presentation material
calibration certificates and records for portable survey instruments for 2021 to 2023
surveillance and calibration records for area radiation and continuous air monitors
various reports for 2021, 2022, and 2023 including Radiation Safety Annual Reports and quarterly radiation surveys
radiation safety manual, dated June 2019 b.
Observations and Findings (1) Postings and Notices During tours of the facility, the inspector observed postings required by 10 CFR Parts 19 and 20 at the entrances to various controlled areas including the reactor room and storage areas. The inspector found that areas of the facility were posted as required, and that no unmarked radioactive material was found in the facility.
The inspector verified a copy of the current NRC Form 3, Notice to Employees, was posted.
(2) Dosimetry The inspector confirmed that dosimetry was used by facility personnel and verified that the licensee used a National Voluntary Laboratory Accreditation Program accredited vendor to process personnel dosimetry. The inspector verified that the quarterly occupational doses were within 10 CFR Part 20 limits.
(3) Radiation Monitoring Equipment The inspector reviewed the surveillance and calibration records for portable radiation detection, area radiation monitors, and air monitoring equipment for the inspection period. The inspector noted that survey meters are sent to an outside company for calibration. The inspector confirmed that the portable survey meters, area radiation monitors, and air monitoring equipment were calibrated within the calibration frequency as required by TS section 4.7.

(4) Radiation Protection Program and Training The inspector verified that the radiation protection program was evaluated by the Radiation Safety Officer annually as required by TS. The inspector found that licensed operators were tested on principles of health physics as well as reactor operations. The inspector confirmed that annual training was provided to RCF staff members, and all current staff completed the required training.
(5) Environmental Monitoring During a tour of the exterior of the RCF, the inspector observed six thermoluminescent dosimeters placed around the perimeter fences. The inspector found that all dosimeters were present, at a sufficient level about the ground, and secured to the fence. The inspector verified that recorded doses were well below the applicable regulatory limits. The inspector confirmed that these results were also reported in the facility annual reports. The inspector verified that there were no effluent releases from the RCF to the environment during the past 3 years.

7. Previously Identified Inspection Follow-up and Unresolved Items a.
Inspection Scope (IP 92701)
To verify the corrective actions taken by the licensee to address a violation of requirements regarding testing and calibrating monitoring equipment specified in TS section 4.7 (VIO 50-225/2021201-01), the inspector reviewed the following:
surveillance and calibration records for area radiation monitors and the continuous air monitor (CAM)
various reports for 2021, 2022, and 2023 including radiation safety annual reports and quarterly radiation surveys b.
Observation and Findings During a previous inspection in October of 2021 (Inspection Report No.
05000225/2021201), an inspector found that the licensee failed to test the CAM and area radiation monitors within the monthly surveillance interval specified and failed to calibrate the CAM within the semiannual surveillance interval required by TS section 4.7.
The licensee responded to the violation by letter dated January 5, 2022, in which the licensee outlined the problem and the corrective actions taken. The problem occurred with the onset of the COVID-19 pandemic and the RPI administrations directive to minimize RCF operations. An exacerbating factor was the staffs misinterpretation of TS Section 4.2 listing of various surveillances required to ensure that all reactor control and safety systems are operable. The eighth specification in the TS Section 4.2 list states that, Requirements 1 through 6 may be waived when the instrument, component, or system is not required to be operable, but a channel test shall be performed on the instrument, component or system prior to being declared operable.
Several surveillances were safely postponed during the period from March 2020 until August 2021. However, RCF staff incorrectly applied this criterion to TS Section 4.7 which applied to checking the CAM [continuous air monitor] and area radiation monitors monthly and calibrating these instruments semiannually.
The licensee took various corrective actions including revision of the checklist to clearly indicate which surveillances can be postponed and which must be completed regardless of operation status. This checklist is stored in the RCFs dual-verification-secured RPI BOX system which can be accessed by all staff members. In addition, all staff members reviewed the changes and discussed the importance of complying with the requirements stated in the TSs. This checklist revision and the return to a normal operation schedule have resulted in consistency in compliance.
The inspector reviewed the testing and calibration intervals of the CAM and area radiation monitors for the past 2 years during this inspection. The inspector verified that the test and calibration intervals were as specified in the TSs. Because RPI tested and calibrated the monitors within the time frames required by the TSs, the inspector noted that this issue was appropriately corrected to mitigate recurrence.

c.
Conclusion The inspector determined that a previous violation (VIO 50-225/2021201-01) is closed.
8. Exit Interview The inspector summarized the scope and results of the inspection on September 20, 2023, with members of licensee management and staff. The inspector described the areas inspected and discussed the inspection findings. The licensee acknowledged the findings presented and did not identify as proprietary any of the material provided to or reviewed by the inspector during the inspection.
