Observations and Findings (1)
Surveys The inspector reviewed monthly radiation and contamination surveys of licensee-controlled areas for the past 2 years. The inspector determined that the results of these surveys were documented, reviewed, and evaluated, and corrective actions were taken when readings or contamination results exceeded set action levels.
(2)
Postings and Notices During tours of the facility, the inspector observed that postings and controls established for radiation, high radiation, contamination, and radioactive storage areas met the requirements of 10 CFR Part 20, Subpart J, Precautionary Procedures. The inspector confirmed that personnel complied with the signs, postings, and controls.
(3)
Dosimetry The inspector determined that the licensee used appropriate dosimetry for monitoring personnel radiation dose. Through direct observation the inspector determined that dosimetry use by facility personnel was in accordance with the university radiation protection requirements.
Examination of the dosimetry results, indicating radiological exposures at the facility for the past 2 years, showed that all occupational doses were within 10 CFR Part 20 limits.
(4)
Radiation Monitoring Equipment Use and Calibration The use and calibration of radiation monitoring equipment was reviewed by the inspector. The inspector reviewed calibration records and determined that records were maintained as required, and that calibration frequencies met the requirements established in the applicable
surveillance procedures. Through observations of activities at the MSTR facility, the inspector determined that monitoring equipment was used in accordance with facility procedures.
(5)
Radiation Worker Training The inspector determined that licensed operators at MSTR were tested annually on principles of health physics, and that MSTR personnel authorized to work with radioactive material under the campus material license received annual refresher training.
The inspector reviewed documentation of the training provided to MSTR staff members and the documents indicated that all current staff members received the required training. The inspector determined that the personnel training program satisfied requirements in 10 CFR 19.12, Instruction to workers.
(6)
Environmental and Effluent Monitoring i.
Observations The inspector reviewed the area radiation monitors (ARMs) and the continuous air monitor (CAM) calibration records. The inspector verified that the ARMs and CAM were calibrated annually by licensee staff in accordance with procedures.
The inspector verified that there were no liquid releases from the facility to the sanitary sewer within the past 2 years. It was noted by the inspector, that solid waste was transferred from the facility to the campus Radiation Safety Officer (RSO).
The inspector noted that onsite and off-site gamma radiation monitoring was completed using environmental dosimetry in accordance with the applicable university procedures. The data indicated that there were no unusual dose rates in the areas surrounding the MSTR facility and that there were no measurable doses above any regulatory limits. These results were also appropriately reported in the facility annual reports ii.
Inspector Follow-up Item (IFI) 50-123/2019-201-01, Use of the Environmental Protection Agency (EPA) COMPLY Code to Calculate Off Site Releases.
IFI 50-123/2019-201-01 was opened in 2019 to track the licensees review of the requirements for calculating off site airborne radioactivity releases. During the current inspection, the inspector found that the licensee has completed its review and determined that use of the EPA COMPLY code is not mandatory and hand calculations are acceptable. This IFI is closed.
iii. Notice of Violation (NOV) 05000123/2021-201-01 of TS 4.6.2, Radioactive Effluents, Due to Testing and Calculation Errors.
Section 4.6.2(1) of the TS states, An experimental verification of calculated release [of radioactive effluent] values shall be performed every 5 years and when a change in licensed power occurs.
Contrary to the above, due to errors in experimental verification methodology, the licensee failed to conduct a valid experimental verification of airborne radioactive effluent values since 2007.
The inspector found that the methodology employed for the experimental verification of airborne releases from the MSTR facility from 2008 to 2019 did not establish a ventilation configuration that was consistent with assumptions in the airborne radioactivity calculations used to determine the magnitude of MSTR airborne radioactive effluents. This error resulted in the licensee underestimating the amount of airborne radioactivity released from the MSTR facility.
However, after the inspector identified this error, the licensee performed an in-depth review of the testing methodology and found additional errors (see MSTR event notification 55266 follow-up reports, Agencywide Documents Access and Management System Accession Nos. ML21153A432 and ML21153A433). The cumulative effect of the errors is that airborne radioactive effluents were significantly underestimated between 2008 and 2019. The inspector noted that, despite the inaccurate testing results, once corrections to data were applied, it is reasonable to assume that the airborne radioactive effluents from the MSTR facility were with the limits established in 10 CFR 20.1101, Radiation protection programs, paragraph (d) and 10 CFR Part 20, Appendix B, Table 2.
(8)
Facility Tours The inspector toured the reactor building and found that control of radioactive material and control of access to radiation and high radiation areas were acceptable and in accordance with the regulations. As noted earlier, the postings and signs for these areas were appropriate. No problems were noted.
c.
Conclusion With the exception noted above. the inspector determined that the licensees radiation protection program satisfied regulatory requirements.
5.
Committees, Audits and Reviews a.
Inspection Scope (IP 69001, Section 02.09)
The inspector reviewed the following documents to ensure that the requirements of TS Section 6.2 were met:
annual independent audits conducted for MSTR by University of Missouri-Columbia Research Reactor staff members for 2019 and 2020
RSC meeting minutes for 2019 to the present
annual ALARA audits conducted in 2019 and 2020 b.
Observations and Findings The inspector found that RSC membership satisfied TS Section 6.2.2 requirements and that the committee provided oversight for the reactor as required by the TS. The inspector noted that RSC minutes and audit records showed that safety reviews and individual audits were completed at the required frequency for the functional areas specified by TS Sections 6.2.3 and 6.2.4.
c.
Conclusion The inspector found that the RSC continued to perform independent oversight in accordance with TS requirements.
6.
Transportation Activities a.
Inspection Scope (IP 86740)
The inspector interviewed personnel and reviewed the following to verify compliance with regulatory and procedural requirements for transferred licensed material:
records of radioactive material shipments and transfer for 2019 and 2020
SOP-604, Radioactive Waste Handling b.
Observations and Findings The inspector verified that radioactive material waste generated at the MSTR and was transferred to the Missouri University of Science and Technology campus material license. The inspector found that these transfers were performed in accordance with RSO and facility guidelines.
c.
Conclusion The inspector determined the radioactive material transfers were made in accordance with the applicable procedures and regulatory requirements.
7.
Exit Meeting The inspection scope and results were summarized on May 19, 2021, and May 26, 2021, with members of licensee management and staff. The inspector described the areas inspected and discussed the inspection results.
