2017 ANNUAL REPORT INTRODUCTION The Armed Forces Radiobiology Research Institute (AFRRI) reactor facility was shut down the entire year undergoing installation of a new instrumentation and control system by contractors from General Atomics. This installation and testing is expected to continue for several months into 2018. There were no unscheduled shutdowns during 201 7.

The 201 7 annual reactor audit required by the reactor technical specifications was conducted by Mr. Jere Jenkins in February 2018. Mr. Jenkins was formerly with the Purdue University reactor facility. 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 2017. One minor violation was identified concerning vehicle parking under the AFRRI reactor Physical Security Plan. The AFRRI response to the violation was submitted as required.

There were two RRFSS membership changes during the year. There was one reactor staff arrival and no 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.a. of the Technical Specifications.

Miller Reactor Operations Specialist - Leo Bobek Health Physics Specialist - Joe Pawlovich Chairman and Director's Representative -Dr. David Lesser Recorder - Harry H. Spence Two meetings were held in 2017:

20 June 30November

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 was one design change to the reactor facility during 201 7 that was reviewed and approved under provisions of 10 CFR 50.59:

14 June - A toggle switch was installed to permit remote testing of the reactor exhaust damper flow failure closure system as required by section 4.4 (3) of the new Technical Specifications.

This installation was designed and tested to ensure that its installation or operation would not increase the likelihood of a malfunction or consequences of a malfunction of a SSC_ important to safety or create the possibility of a different type of accident than previously evaluated. Any failure of the remote test switch would simply leave the facility with the exhaust dampers closed thereby limiting release of radioactive effluents to the environment as designed.

B. PERFORMANCE CHARACTERJSTICS There were no changes to the performance characteristics of the core during 2017. Sufficient fuel elements were* withdrawn from the core before beginning the instrumentation upgrade to ensure that the reactor could not become critical at any time during the upgrade.

C. ADMINISTRATIVE PROCEDURES There were no changes to the Administrative Procedures during 2017.

D. OPERATIONAL PROCEDURES There were two changes to the Operational Procedures during 201 7:

09 January - Changes were made to the Weekly Instrument Checklist to ensure compliance with the new Technical Specifications and to ensure that all weekly surveillance requirements would still be met during the instrumentation upgrade when the normal reactor console would not be available. Several obsolete checks that had no bearing on potential reactor accidents or malfunctions were also removed.

13 June - Surveillance Procedure SOlO was changed so that required fuel measurement/inspection could be performed during the instrumentation upgrade while there was no functional reactor console. The former procedure specified that a SRO must monitor

the reactor power level "on console" during fuel movement. The new procedure allows a SRO to monitor the power level from the reactor deck using a remote readout from the same in-core chamber and calibrated power-monitoring channel as before. The only difference is the location of the monitoring SRO who is still in communication with the personnel moving fuel.

E. RESULTS OF SURVEILLANCE TESTS AND INSPECTIONS All maintenance and surveillance tasks during 2017 were accomplished as normally scheduled during the year except those tasks involving the reactor instrumentation, control rod drives, or other related components. All tasks deferred during the instrumentation upgrade will be accomplished before the reactor is returned to normal operation.

There were no reactor malfunctions during 2017.

The 201 7 annual reactor audit required by the reactor technical specifications was conducted by Mr. Jere Jenkins in February 2018. Mr. Jenkins was formerly with the Purdue University reactor facility. 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 2017. One minor violation was identified concerning vehicle parking under the AFRRI reactor Physical Security Plan. The AFRRI response to the violation was submitted as required.

SECTION III Unscheduled Shutdowns There were no unscheduled shutdowns during 2017.

SECTION IV Safety-Related Corrective Maintenance There were no reactor malfunctions during 2017.

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 There were no changes to the facility as described in the FSAR.

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 three safety evaluations for changes not submitted to the NRC, pursuant to the provisions of 10 CPR 50.59 (see Sections I.A. and I.D. above).

SECTION VI Summary of Radioactive Effluent Released A. Liquid Waste: The reactor produced no liquid waste during 2017.

B. Gaseous Waste: There were no particulate discharges in 2017.

The total activity of Argon-41 discharged in 2017 was 0.0 curies because the reactor was shut down for the entire year. The estimated effluent concentration from the release of Argon-41 represents 0% of the constraint limit for unrestricted areas (10 CFR 20.1 lOl(d) and Table 2, Appendix B, 10 CFR 20).

Quarterly: Jan - Mar 2017 0.00 Ci Apr - Jun 2017 0.00 Ci Jul - Sep 2017 0.00 Ci Oct - Dec 2017 0.00 Ci C. Solid Waste: All solid radioactive waste material was transferred to the AFRRI byproduct license; none was disposed of under the R-84 reactor license.

SECTION VII

  • 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 2017, was 0.00 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 20.1 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 0.00 millirem, or 0% 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% of 10 CFR 20 Limits There were no doses to reactor staff personnel or reactor visitors greater than 25% of 10 CFR 20 occupational and public radiation dose limits.
