Radiation Safety for Radiation Workers, and in various UWNR Laboratory guidance documents and procedures. The ALARA program provided guidance for keeping doses as low as possible and was consistent with the guidance in 10 CFR Part 20.

(6) Radiation Protection Training The inspector verified that people who handled radioactive material, including licensee personnel, were required to receive training in radiation protection as noted above. This was accomplished by staff members watching a video, attending a class, and successfully passing a written examination. The inspector confirmed that completion of this training by reactor staff personnel was verified by EH&S Department personnel as well as by the Reactor Director and/or the Reactor Supervisor. Radiation protection refresher training was conducted annually. The inspector verified that all reactor staff members had completed the initial and all subsequent training as required.

(7) Effluent and Environmental Monitoring The inspector reviewed the calibration records of the area radiation monitors and the stack monitoring system and verified that these systems were calibrated annually according to procedure. The weekly start-up check records for the monitoring equipment were also reviewed. The inspector determined that checks were completed as required by procedure.

The inspector reviewed the records documenting liquid releases to the sanitary sewer for the past 2 years. The inspector determined that an SRO approved liquid releases only after analyses indicated that the releases would meet regulatory requirements for discharge. The inspector also reviewed the records documenting the disposal of solid waste for the past 2 years. The inspector confirmed that solid waste was surveyed, characterized, and transferred to the UW EH&S Radiation Safety Unit for disposal. The releases and transfers were accomplished in accordance with procedure and the results of the releases and waste transfers were acceptably documented in the operating log records as well as in the Annual Operating Reports as required.

The inspector determined that on-site and off-site gamma radiation monitoring was accomplished using various environmental OSL dosimeters in accordance with the applicable procedures. The inspector verified that OSL dosimetry data indicated that doses to the public did not exceed any regulatory limits. These results were also acceptably reported in the Annual Operating Reports for fiscal years 2017-2018 and 2018-2019, as required by TSs.
