Subject:
Transmittal of Semiannual Effluent Report (2 copies)
Docket Nos. 50-89, 50-163 and 70-734; License Nos. R-38, R-67 and SNM-696, Respectively
Dear Mr. Wert:
In accordance with 10 CFR 70.59, General Atomics (GAj herewith transmits the required semiannual effluent report for the period July 1, 2005 through December 31, 2005.
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, Radiologic Health Branch.
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 2 in the report, a plan view of GAs 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. There was no radiological liquid effluent released 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

SEMIANNUAL EFFLUENT REPORT FOR THE PERIOD July I,2005 through December 31,2005 Prepared By Edward Rudgers Reviewed by Laura Gonzales February 2,2006
Semiannual Effluent Report Summary In accordance with 10 CFR 70.59, GA has prepared the semiannual effluent report for the period July 1, 2005 through December 31, 2005.
Table 1 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: There were no releases during this report period.

Buildiizg 21 Rooin 104 I H-3 I (I) Measured - Airborne effluents from selected facilities are monitored. The samples are collected weekly and analyzed using low-level alphalbeta 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
('1 There were no releases during this report period.
