The reactor license renewal application, submitted in June 2004, was approved by the NRC with the issuance of a new 20-year operating license on November 30, 2016. Numerous revisions to both the Technical Specifications and the Safety Analysis Report were submitted as part of the relicensing process and were approved by the NRC. There were no major reactor modifications or projects during the year except preparation for installation of the new reactor console after December 7. There were no unscheduled shutdowns during 2016. The 2016 annual reactor audit required by the reactor technical specifications was conducted by Mr. Bob Woodruff in January 2017. Mr. Woodruff is a health physicist in the Military Medical Operations Division.

During the audit he verbally indicated that he had not found any major discrepancies in reactor operations and those conclusions are reflected in his written report. A comprehensive NRC inspection of reactor facility operations and security was conducted by Mr. Johnny Eads during January 2016. While he had several recommendations for improving reactor operations, no safety concerns or noncompliance with NRC requirements were identified.

There were two RRFSS membership changes during the year. There were two reactor staff arrivals and three staff departures during the year. The remainder of this report is written in the format designated in the Technical Specifications for the AFRRI TRIGA Reactor Facility.

Items not specifically required are presented in the General Information section. The following sections correspond to the required items listed in Section 6.6.b. of the Technical Specifications.

, SECTION I Changes in the Facility Design, Performance Characteristics, Administrative Procedures, Operational Procedures, Results of Surveillance Tests and Inspections A summary of changes to the facility design, performance characteristics, administrative procedures, and operational procedures as well as the results of surveillance testing are provided in this section. A. DESIGN CHANGES There were two design changes to the reactor facility during 2016 that were reviewed and approved under provisions of 10 CFR 50.59: 23 February-Addition of incandescent lamps to visually check the status of the transient rod up and down limit switches.

19 May -Removal and replacement of the automatic secondary water treatment system. This involved the upgrading of a former cooling tower water treatment system that was installed in September 2004 after 10 CFR 50.59 approval.

Revisions were also made to Chapter 7, Instrumentation and Control Systems, of the FSAR to complete the relicensing package and to prepare for the installation of the new reactor console in 2017 (see Section V). B. PERFORMANCE CHARACTERISTICS There were no changes to the performance characteristics of the core during 2016. All fuel elements and control rods remained in place for operations throughout the year until December 7 as noted in the Introduction.

C. ADMINISTRATIVE PROCEDURES There were no changes to the Administrative Procedures during 2016. D. OPERATIONAL PROCEDURES There were no changes to the Operational Procedures during 2016. E. RESULTS OF StJRVEILLANCE TESTS AND INSPECTIONS I All maintenance anq surveillance tasks during 2016 were accomplished as normally scheduled during the year. There were no reactor malfunctions during 2016.

The 2016 annual reactor audit required by the reactor technical specifications was conducted by Mr. Bob Woodruff in January 2017. Mr. Woodruff is a health physicist in the Military Medical Operations Division.

During the audit he verbally indicated that he had not found any major discrepancies in reactor operations and those conclusions are reflected in his written report. A comprehensive NRC inspection of reactor facility operations and security was conducted by Mr. Johnny Eads during January 2016. While he had several recommendations for improving reactor operations, no safety concerns or noncompliance with NRC requirements were identified.

SECTIONV Facility and Procedure Changes as Described in the Final Safety Analysis Report (FSAR), New Experiments or Tests Performed During the Year A. FACILITY CHANGES AS DESCRIBED IN THE FSAR Chapter 7, Instrumentation and Control Systems and Chapter 13, Accident Analysis of the FSAR were extensively revised during the reactor relicensing process and were approved by the NRC when the licensed was renewed on November 30.

B. PROCEDURE

CHANGES AS DESCRIBED IN THE FSAR There were no changes to procedures as described in the FSAR. C. NEW EXPERIMENTS OR TESTS No new experiments or tests were performed during the reporting period that were not encompassed by the FSAR. There were two safety evaluations for changes not submitted to the NRC, pursuant to the provisions of 10 CFR 50.59 (see Section I.D. above).

SECTION VI Summary of Radioactive Effluent Released A. Liquid Waste: The reactor produced no liquid waste during 2016. B. Gaseous Waste: There were no particulate discharges in 2016. C. Solid Waste: SECTION VII The total activity of Argon-41 discharged in 2016 was 1.22 curies. The estimated effluent concentration from the release of Argon-41 represents under 1 % of the constraint limit for unrestricted areas (10 CFR 20.1 lOl(d) and Table 2, Appendix B, 10 CFR 20). Quarterly:

Jan -Mar 2016 Apr -Jun 2016 Jul -Sep 2016 Oct-Dec 2016 0.70 Ci 0.32 Ci 0.15 Ci 0.05 Ci All solid radioactive waste material was transferred to the AFRRI byproduct license; none was disposed of under the R-84 reactor license. Environmental Radiological Surveys All environmental sampling of soil and vegetation yielded radionuclide levels within the background range. The radionuclides that were detected were those expected from natural background and from long-term fallout from nuclear weapons testing. The calculated annual dose, due to Argon-41 release to the environment for 2016, was 0.04 mRem at the location of maximum public exposure.

The maximum exposure is calculated at a location 91 meters from the release point as described in the FSAR. Exposure to the general population at the boundary of the Naval Support Activity Bethesda is significantly less due to the diffusion of Argon-41 in the atmosphere.

The constraint limit for exposure to the public established under 10 CFR 20.l lOl(d) is 10 millirem per year. The exposure dose was calculated using COMPLY code, level 2, which is the most conservative level of COMPLY. Emissions due to reactor operations were 0.04 millirem, or less than 1 % of the 10 millirem constraint limit, for the entire year. The reactor in-plant surveys, specified in Health Physics Procedure (HPP) 3-2, all resulted in readings that were less than the action levels specified in HPP 0-2.

. ' SECTION VIII Exposures Greater than 25°/o of 10 CFR 20 Limits There were no doses to reactor staff personnel or reactor visitors greater than 25% of I 0 CFR 20 occupational and public radiation dose limits.
