1. INTRODUCTION This report documents operation of the General Atomics (GA) TRIGA1 Mark I Non-Power Reactor for the period January 1, 2016 through December 31, 2016. The TRIGA Mark I Reactor, possessed by GA at Its San Diego, California facilities as authorized under License No.

R-38 (Amendment No. 36) granted by the U.S. Nuclear Regulatory Commission (Docket No. 50-

89) was not operated during the reporting period.

This report is being prepared and submitted to satisfy the requirements of Section 7.6(d) of the R-38 Technical Specfflcations, as amended. This report is presented in six parts, consistent with the information required by the applicable Technical Specifications.

2.

SUMMARY

OF FACILITY ACTIVITIES 2.1 Decommissioning Activities During Calendar Year (CY) 2016, the TRIGA Mark I Reactor was in Decommissioning Status.

The primary task accomplished during this reporting period was sectioning and gamma scanning nine (9) core samples taken from the Mark I reactor pit in CY2000. In addition, gamma scan data from nineteen (19) other core samples taken in CY2000 was 11decayed* to present day levels.

2.2 Facility Status The Mark I reactor was in DECON status during CY 2016. There have been no changes since the last reporting period.

2.3 Decommissioning Schedule Decommissioning of the Mark I Reactor wllf continue upon completion of the characterization of the biological shleld and soil behind the shield and beneath the floor of the reactor pit.

Extraction of an additional ten (10) core samples is planned for CY2017 to allow full characterization of the volume of material requiring removal. Folfowing analysis of the sample results, a statement of work is expected to be written for structural analysis and excavation/remediation. This will be coordinated with the Mark F reactor decommissioning efforts in order to better utilize personnel, equipment and material.

2.4 Radioactive Material Shipments During 2016 there were no radioactive shipments or transfers made from the Mark I facility.

3. MAINTENANCE OPERATIONS All maintenance activities performed during the reporting period generally fall Into three categories: (i) routine preventive maintenance, (ii) routine calibration activities, and (iii) activities associated with replacement of order components and systems due to age. All maintenance activities are recorded In the TRIGA Reactor Facility Decommissioning Logbook. Facility Maintenance Checklists are completed on a regular schedule, at weekly, quarterly. and annual frequencies. Alf maintenance operations performed on the TRJGA Mark I Reactor Facllity were minor fn nature. There were no major maintenance operations performed during the reporting period.

1. INTRODUCTION This report documents operation of the General Atomics (GA) TRIGAet Mark F non-power reactor for the period January 1, 2016 through December 31, 2016. The TRIGA Mark F Reactor possessed by GA under License No. R--67 (Amendment No. 45) granted by the U.S. Nuclear Regulatory Commission (Docket No. 5()..163}, at its San Diego, Cslifomia facilities, was not operated for the duration of the reporting period.

This report is being prepared and submitted to satisfy the requirements of Section 8.6{d) of the R-67 Technical Specifications, as amended. This report is presented in six parts. consistent with the information required by the applicable Technical Specifications.

2.

SUMMARY

OF FACILITY ACTIVITIES 2.1 Decommissioning Status During Calendar Year (CY) 2016. the TRIGA Mark F Reactor was in a Decommissioning status.

The major tasks accomplished during this reporting period were:

• Gamma scanned and analyzed twenty (20) core samples taken from within the reactor pit and fuel storage canal. The data acquired was used to estimate the volume of concrete/steel/soil in the Mark F structure that will require removal.

• 3D renderings of the Mark F facility and volume of reactor pit concrete having activation in excess of requested, but at the time not yet NRC-approved, release criteria were prepared to assist in excavation planning.

2.2 Facility Status The Mark F reactor was in DECON status during CY 2016. The reactor pit/canal has been remediated of hazardous contaminants and core samples extracted.

2.3 Decommissioning Schedule Twenty (20) core samples were collected from the Mark F pit/canal walls and floor during CY 2015. Certain of the results showed measurable quantities of Co-60, Eu-152 and Eu154.

Statistical analyses Indicated the twenty core samples were adequate to allow full characterization of the volume of material requiring remediation/removal. The extent of volumetric activation/contamination and thus the quantity of material (gunite, steel, concrete and soil) requiring removal was estimated in early 2016 based on requested. but not yet NRC-approved, release criteria. A statement of work is expected to be written for structural analysis and excavation in early 2017.

2.4 Radioactive Material Shipments During 2016 four (4) separate radioactive shipments or transfers were made from the TRIGA Mark F facility to various disposal facilities.

On April 6. 2016, one Am-Be Neutron Source, SIN MRC-AmBe-2289, which had been exposed in the TRIGA Mark F Reactor, was packaged and shipped to NSSI. Houston, TX, for eventual disposal. For this shipment. the DOE's Off-Site Source Recovery Program assisted GA with 1

packaging and transport logistics. The transport 55 gal steel drum package, which was classified as RQ UN3332 Radioactive Material, Type A Package, Special Form. 7, weighed 580 lbs.* and contained a total of 5.75 Ci of Pu-238 and Am 241 as solid oxide.

4 On. July 13, 2016, one surplus contaminated lead cask, which had served as the TRIGA Single Element Transfer Cask, was packaged and shipped to Alaron Nuclear Services, Wampum, PA, for decontamination and disposal. Philotechnics acted as GA's waste broker. The transport 55 gal. steel drum package was classified as UN2910, Radioactive Material, excepted package -

limited quantity, weighed 500 lbs, and contained a total of 0.91 mCi of Co-60 and Cs-137 as solid oxide.

On November 30, 2016, five steel IP-1 Boxes of decontamination solid waste was shipped to the Nevada National Security Site, Mercury, NV, for disposal. Three of the five 1Pw1 containers were classified as UN2912,Radioactive Material, Low Specific Activity (LSA*I). The remaining two IP-1 containers were Non-Regulated per DOT. Collectively, the five IP-1 Boxes weighed 12,106 lbs., and contained 2.37 mCi of Co-60 as solid oxide.
