Introduction This report documents operation of the General Atomics (GA) TRIGA Mark I Non-Power Reactor for the period January 1, 2002 through December 31, 2002. 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 2002, the TRIGA Mark I has been in Decommissioning status. Activities performed during this period were:

The 8000 gallon demineralized water storage tank was surveyed by Health Physics and declared clean. The tank was disposed of as clean waste.

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 remains deferred until shipment of the fuel from the Mark F Reactor pool for safety reasons.

o The Senior Reactor Operators (SROs) have all maintained their licensing requirements to keep their licenses current.

o The Criticality and Radiation Safeguards Committee (CRSC) performed their annual inspection on November 6, 2002. 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. All packaged radioactive materials have been shipped.

1.4 Radioactive Material Shipments Listed below are the radioactive waste shipments, associated with the TRIGA Mark I Reactor decommissioning activities, made from General Atomics, San Diego, CA, to the U.S. Department of Energy, Nevada Test Site (NTS),

Mercury, NV, during the Calender Year 2002 reporting period. Each Low Specific Activity Radioactive Waste Box (LSA Box) mentioned below represents a radioactive waste disposal volume of 123.2 ft3. Each drum shipped was a 55 gallon container o

Three (3) LSA boxes of contaminated soil were shipped on 4/16102.

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.

4.

Radioactive Effluents Released to the Environs During Calendar Year 2002, 0.00 millicuries of Argon-41 were discharged from the TRIGA Mark I Reactor facility stack to the atmosphere.

5.

Environmental Surveys During Calendar Year 2002, 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 A Continuous Air Monitor (CAM), situated in the Mark I Reactor Room (Rm.

21/102) to continuously sample room air for airborne radioactivity. CAM air filters are collected each week and analyzed for radioactivity.

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 Calendar Year 2002.

Personnel who are listed on the TRIGA Reactor Facility Work Authorization (WA #3227) and specific Radiation Work Permits (RWPs) were monitored for radiation exposure; these individuals included 11 General Atomics employees and 5 sub-contractor employees.
