Transmittal of Semiannual Effluent Report (2 copies); License 01 45-37

Dear Mr. Wert and Dr. Rogus:

In accordance with 10 CFR 70.59, General Atomics (GA) herewith transmits the required semiannual effluent report for the period January I

, 2007 through June 30, 2007.

By copy of this letter, one copy of this report is being forwarded to the Director, Office of Nuclear Material Safety and Safeguards, U. S. Nuclear Regulatory Commission. Additional copies are being sent to the State of California, Department of Health Services.

Table 1 of the report lists data on the radiological gaseous and particulate effluent released to unrestricted areas from our facilities handling radioactive material. The release point descriptions are keyed to the facility names whose relative locations are shown on Figure 1 in the report, a plan view of GA's Main Site and Sorrento Valley sites. Attachment A provides detailed information concerning airborne effluent stack sample results over this reporting period. All airborne releases were well within the allowable State of California and NRC (10CFR20) limits. Table 2 provides the liquid effluent released into the sanitary sewerage system during this report period.

We trust the information provided is satisfactory to meet the requirements for this submission. If you should have any questions regarding this information, please contact Ms.

Laura Q. Gonzales at (858) 455-2758, or me at (858) 455-2823.

Very truly yours, Dr. Keith E. Asmussen, Director Licensing, Safety and Nuclear Compliance

Semiannual Effluent Report Summary In accordance with 10 CFR 70.59, GA has prepared the semiannual effluent report for the period January 1,2007 through June 30,2007.

Table I lists data on the radiological gaseous and particulate effluent released to unrestricted areas from our facilities handling radioactive material. The release point descriptions are keyed to the facility names whose relative locations are shown on Figure 1, a plan view of GA's main site and GA's Sorrento Valley site. Attachment A of the report provides detailed information concerning airborne effluent stack sample results over this reporting period. All airborne releases were well within the allowable State of California and NRC 10CFR20 limits.

Table 2 provides the radiological liquid effluent which was released into a 100 million gallon/day regional sewerage treatment plant. Note: The only release during this report period was from a tenant (Ferring Reasearch) occupying laboratory space in GA's Building

Measured - Airborne effluents from selected facilities are monitored. The samples are collected weekly and analyzed using low-level alpha/beta counting systems. The average concentration (pCi/m3) over the six month period is obtained for each release point (alpha and beta concentrations are added). See Attachment A

()

There were no releases during this report period.

(3) Ci Released = (1 81 operating days) (24 hr/day)(60 min/hr) (1 e-6 pCi/pCi)

(1 e-6 Ci/pCi) (# m3/min)(average pCi/m3) Note: Operating days may be different based on dates the ventilation system was shut down.

Flow rate x stack area (Note: 0.0283 m3 = 1 ft3).

Calculated based on operating time of the fusion device.
