Introduction This report documents operation of the General Atomics (GA) TRIGAP Mark I Non-Power Reactor for the period January 1, 2004 through December 31, 2004. The TRIGA Mark I Reactor, possessed by GA at its San Diego, California facilities, was not operated for the duration of the reporting period. The Reactor is possessed by GA under License No. R-38 (Amendment No. 36) granted by the U.S. Nuclear Regulatory Commission (Docket No. 50-89).
This report is being prepared and submitted to satisfy the requirements of Section 7.6(d) of the R-38 Technical Specifications, as amended. This report is presented in six parts, consistent with the information required by the applicable Technical Specifications.

Summary of Facility Activities 1.1 Decommissioning Activities During Calendar Year (CY) 2004, the TRIGA Mark I has been in Decommissioning status. The following represents a summary of activities during this reporting 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. 211107.
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 maintained their licensing requirements to keep their licenses current. The biennial written exam was taken by the three (3) operators on May 26, 2004.
o The Criticality and Radiation Safeguards Committee (CRSC) completed its annual inspection on November 10, 2004. No problems were noted.
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 2004 reporting period.
- 2.
Maintenance Operations All maintenance activities, performed during the reporting period, generally fall into three categories: (l) 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 2
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, under the provisions of 10CFR50.59, submitted for the R-38 facility during the CY2004 reporting period.
There were no Special Experiments submitted for the R-38 facility during CY2004.
- 4.
Radioactive Effluents Released to the Environs During CY2004, 0.00 millicuries of Argon-41 were discharged from the TRIGA Mark I Reactor facility stack to the atmosphere.
- 5.
Environmental Surveys During CY2004, 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.
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.

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 CY2004.
Personnel who are listed on the TRIGA Reactor Facility Work Authorization (WA
- 3273) and specific Radiation Work Permits (RWPs) were monitored for radiation exposure; these individuals included 27 General Atomics employees and 19 sub-contractor employees.
