b. Observations and Findings (1) Surveys Selected start-up and monthly radiation and/or contamination surveys were reviewed by the inspector. The surveys had been completed by staff members as required. Any contamination detected in concentrations above established action levels was noted and the area was decontaminated. Results of the surveys were documented so that facility personnel would be knowledgeable of the radiological conditions that existed in the controlled areas of the facility.

(2) Postings and Notices Radiological signs were posted at the entrances to controlled areas.

Caution signs, postings, and controls for radiologically controlled areas were as required in 10 CFR Part 20, Subpart J. Other postings at the facility showed the industrial hygiene hazards that were present in the areas as well.

Copies of NRC Form 3, "Notice to Employees," noted at the facility were the latest version, as required by 10 CFR 19.11, and were posted in various areas throughout the facility. These locations included the bulletin boards in the hallways by each entrance to the facility protected area and in the hallway by the facility calibration range. Copies of other notices to workers were posted in appropriate areas in the facility. (3) Dosimetry The inspector determined that the licensee used thermoluminescent dosimeters (TLDs) for whole body monitoring of beta and gamma radiation exposure with an additional component to measure neutron radiation. The licensee used TLD finger rings for extremity monitoring.

The dosimetry was supplied and processed by a National Voluntary Laboratory Accreditation Program accredited vendor. An examination of the TLD results, indicating exposure to radiation at the facility for the past 2 years, showed that the highest occupational doses, as well as doses to the public, were within 10 CFR Part 20 limits.

(4) Radiation Monitoring Equipment Examination of selected radiation monitoring equipment indicated that the instruments had the acceptable up-to-date calibration sticker attached.

The instrument calibration records indicated that calibration of portable survey meters was typically comp leted by licensee staff personnel. However, some instruments, including the neutron detection instruments, were shipped to vendors for calibration. Calibration frequency met procedural requirements and records were maintained as required. Area radiation monitors and stack monitors were also being calibrated as

required.

(5) Radiation Protection and ALARA Programs The licensee's Radiation Protection and ALARA Programs were established and described in ROM Chapter 8 and through associated GSTR procedures that had been reviewed and approved. The programs contained instructions concerning organization, training, monitoring, personnel responsibilities, audits, record keeping, and reports. The ALARA Program provided guidance for keeping doses as low as reasonably achievable and was consistent with the guidance in 10 CFR Part 20.

The inspector also determined that the licensee had conducted an annual review of the Radiation Protection Program for 2013 and 2014 in accordance with 10 CFR 20.1101(c). This had been completed by the Reactor Supervisor. In addition, annual audits of the ALARA Program had been conducted by USGS Radiation Safety Committee.

The licensee did not require or have a respiratory protection program.

(6) Radiation Protection Training The inspector reviewed the radiation worker training given to staff members, to those who are not on staff but who are authorized to use the experimental facilities of the reactor, and to support personnel. Initial radiation worker training was given to everyone before they started work in the facility. Refresher training for reactor staff was given every 2 years; everyone else received refresher trai ning every 3 years. The inspector noted that the last refresher training had been conducted on February 1, 2013.

The initial and refresher training covered the topics specified in 10 CFR Part 19 as required. Training records showed that personnel were acceptably trained in radiation protection practices. The training program was acceptable.

c. Conclusion The inspector determined that the Radiation Protection and ALARA Programs, as implemented by the licensee, were in a ccordance with regulatory requirements. Specifically, (1) surveys were completed and documented acceptably to permit evaluation of the radiation hazards present; (2) notices and postings met regulatory requirements; (3) personnel dosimetry was being worn as required and recorded doses were well within the NRC's regulatory limits; (4) radiation survey and monitoring equipment was being maintained and calibrated as required; and (5) the radiation protection training program was acceptable.

Observations and Findings On-site and off-site gamma radiation monitoring was completed using the reactor facility stack effluent monitor, various environmental monitoring TLDs, and area monitors in accordance with the applicable procedures. Data indicated that there were no measurable doses above any regulatory limits. Biennial environmental soil and water samples were taken and analyzed in 2014. No reactor-produced isotopes were identified in the samples.

The inspector determined that gaseous releases continued to be monitored and calculated as required, were acceptably documented, and were within the annual dose constraint of 10 millirem stipulated in 10 CFR 20.1101(d), 10 CFR Part 20, Appendix B concentrations, and Technical S pecification limits. Environmental Protection Agency COMPLY code calculations indicated that the facility was in compliance with effluent emissions.

The program for the monitoring, storage, or transfer of radioactive liquid and solids was consistent with applicable regulatory requirements. No liquid discharges had been made during 2013 and 2014. Solid radioactive material was monitored and released when below acceptable limits or was shipped to a waste processing facility for disposal. The principles of ALARA were acceptably implemented to minimize radioactive releases. Monitoring equipment was acceptably maintained and calibrated. Records were current and acceptably

maintained.

c. Conclusion Effluent monitoring satisfied license and regulatory requirements and releases were within the specified regulatory and Technical Specifications limits.

4. Design Changes a. Inspection Scope (IP 69001) In order to verify that the licensee had met the design change requirements of Title 10 of the Code of Federal Regulations (10 CFR) Section 50.59, the inspector reviewed selected aspects of:
