- 1. Summary of Facility Activities 1.1 Decommissioning Activities During Calendar Year (CY) 2005, the TRIGA Mark I has been in Decommissioning status. There were no decommissioning activities performed during this period.
1.2 Facility Status o All TRIGA Mark I fuel remains situated in the Fuel Storage Canal portion of the Mark F Reactor pool, in Rm. 21/107.
o Decommissioning of the contaminated soil around the pit of the Mark I reactor has been deferred until shipment of the fuel from the Mark F reactor pit for safety reasons.
o The Senior Reactor Operators (SROs) have all completed the requirements necessaryto keep their licenses current. The required biennial physical exam was taken by the three (3) operators during August 2005.
o One SRO's license was renewed for a six (6) year period.
o On June 9, 2005, two representatives of the USNRC inspected the TRF as part of the GA site visit to confirm various HP release surveys and to review all recent GA Radioactive Shipping documentation.
o The Criticality and Radiation Safeguards Committee (CRSC) completed its annual inspection on December 14,2005. No problems were noted.
o The roof of Building 21 was surveyed by the General Atomics Health Physics organization. Very low levels of Cs-137 were detected; above background, but below site-wide release criteria.
1.3 Decommissioning Schedule All major task items in the Decommissioning Plan schedule have been completed except for shipment of the fuel from the Mark F storage canal and the decommissioning of the soil around the pit.

1.4 Radioactive Material Shipments There were no shipments of radioactive material during the CY 2005 reporting period.
- 2. Maintenance Operations All TRIGA Mark I 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 older components and systems due to age. All maintenance activities are recorded in the TRIGA Reactors Decommissioning Logbook. Facility Maintenance Checklists are completed on a regular schedule, at weekly, quarterly, and annual frequencies. All maintenance operations performed on the TRIGA Mark I were minor in nature.
There were no major maintenance operations performed during the reporting period.
- 3. 10CFR50.59 Facility Modifications and Special Experiments There were no applications for Facility Modifications to the TRIGA Mark I, under the provisions of 10CFR50.59, submitted during the CY2005 reporting period. There were no new Special Experiments submitted for approval for the R-38 facility during CY2005.
- 4. Radioactive Effluents Released to the Environs During CY2005, 0.00 millicuries of Argon-41 were discharged from the TRIGA Mark I Reactor facility stack to the atmosphere.
- 5. Environmental Surveys During CY2005, the Environmental Monitoring Program (EMP) for the TRIGA Reactors Facility remained essentially unchanged from the prior year. The applicable EMP includes the following monitoring equipment and actions:
o Five (5)emergency air samplers, situated on the Facility roof and around the TRIGA Reactor Facility perimeter.
o Ten (10) environmental air samplers, situated adjacent to, and near the GA site perimeter, in accordance with the GA Material License (SNM-696).
o Daily liquid effluent monitoring from the GA Main Sewerage Outfall Pump House, for gross alpha and beta radioactivity concentrations.
3
o Annual soil and water sampling at ten (10) stations on the GA site, including stations around the perimeter of the TRIGA Reactor Facility.
o External radiation monitoring of the TRIGA Reactor Facility using five (5) passive area dosimeters, as well as radiation meter surveys conducted periodically.
o Since there were no decommissioning activities or fuel stored in the Mark I Facility the use of the Continuous Air Monitor (CAM) was discontinued. It will be placed in use any time in the future when there are decommissioning activities.
- 6. Summary of Radiation Exposures and Radiological Surveys The following data summarizes measured personnel occupational radiation exposures and radiological surveys of the TRIGA Reactor Facility during CY2005.
Personnel who are listed on the TRIGA Reactor Facility Work Authorization (WA
- 3294) and specific Radiation Work Permits (RWPs) were monitored for radiation exposure; these individuals included 19 General Atomics Staff and 17 Non-General Atomics Staff employees.
6.1 General Atomics Staff Whole Body Exposures' Number of individuals monitored: 19 High Exposure: 0.011 Rem Low Exposure: 0.000 Rem Average Exposure: < 0.001 Rem 6.2 Non-General Atomics Staff Whole Body Exposures2 Number of individuals monitored: 17 High Exposure: 0.000 Rem Low Exposure: 0.000 Rem Average Exposure: 0.000 Rem Includes reactor facility staff and facility support staff authorized to work at the TRIGA Reactor Facility. These personnel may also work routinely at other GA radiation facilities; therefore, this dose represents cumulative exposure at all GA facilities.
