Through direct observation, the inspector determined that dosimetry was used in an acceptable manner by facility personnel. For visitors to the facility, radiation exposures are recorded through the permanent staff at the facility. Records indicate that no abnormal readings were obtained.
An examination of the records for the inspection period showed that all exposures were well within NRC limits and within licensee action levels.
All of the staff and researchers associated with the facility wear Optically Stimulated Luminescense Dosimeter (OSLD) badges and minimal doses were recorded for 2015 through present. The as low as reasonably achievable (ALARA) goal specified in the radiation safety procedures is to keep exposures to less than 10 percent of the applicable NRC requirements and the licensee consistently meets this goal.
(4) Radiation Monitoring Equipment The calibration verification of portable survey meters and friskers was completed by a contracted company. The calibration records of portable survey meters, friskers, fixed radiation detectors, and air monitoring equipment in use at the facility were reviewed. Calibration frequency met
-9-the requirements established in TS 4.4 while records were being maintained as required. The inspector verified that proper precautions are always used to maintain doses ALARA while conducting the calibrations. The inspector reviewed the licensees tracking system for ensuring the instrument calibrations are completed on time and found it to be useful.
(5) Radiation Protection Program The licensees Radiation Protection Program (RPP) was established through the procedures. The RPP provides guidance for keeping doses ALARA and is consistent with the guidance in 10 CFR Part 20. The inspector verified that the RPP was being reviewed annually as required by 10 CFR 20.1101, Radiation protection programs, paragraph (c). No issues related to the RPP were identified in the review of the program.
The RSO reviews the overall implementation of the radiation protection program at the DTRR.
The RPP requires that all personnel who work with radioactive materials receive training in radiation protection, policies, procedures, requirements, and the facilities prior to having unescorted access at the facility. The RSO is responsible for conducting the training and all of the training is typically conducted both on a computer and with practical applications. A test is administered at the end of the training to verify that the individuals understood the material presented. The training covered the topics required to be taught in 10 CFR Part 19 and the review of training materials and tests indicated that the staff were instructed on the appropriate subjects.
(6) Facility Tour The inspector toured the reactor facility, counting laboratories and accompanying facilities. Control of radioactive material and control of access to radiation and high radiation areas were observed to be acceptable. The postings and signs for these areas were appropriate.
Licensee personnel followed the indicated precautions for access to controlled areas.
(7) Environmental Monitoring Several OSLDs were placed around the inside walls of the reactor facility and minimal doses were recorded. Records show that there was minimal radiation exposure to the environment from the reactor during the previous year. There was no liquid effluent discharged from the reactor facility. The licensee indicated that gaseous effluents from the reactor facility were less than 1 millirem/year.
