Subject:
Docket 70-734:. SNM-696; Request for Confirmatory Survey l
(Experimental Building - Stage 1)
Reference:
K. E.. Asmussen letter to Robert D. Thmas, " Request for Release of Selected Laboratories to Unrestricted Use l-(Group 3)," dated December 21, 1988
Dear Mr. Thomas:
[.
As you are aware, General Atomics (GA) has been involved in the L
process of decontaminating and obtaining the release to unrestricted use of ce%. portions of its facilitics.
Most recently, GA canpleted.the decontamination and final surveys of an additional portion of its Experimental Building (Building 9) where certain TRIGA fuel fabrication operations had been conducted until about 1975. This area is located in the northwest' corner of Building 9 and prior to 1975 was referred to as the " Hot Suite" area. Note, however, that not l
all roms referred to as being a part of the " Hot Suite" area were involved with the use of radioactive material.
The portion of Building 9 referred to as the " Hot Suite" area is occupied by GA's telummmications group.
Since it is,not feasible to move all of the telecommunication equipment and personnel from the l
entire area at one time GA is surveying and pursuing the release of the area in three (3) stages.
Decontamination of the first stage, i.e.,
" Stage.1," area has been completed and the results of GA's final radiation and contamination surveys are documented in the enclosed report.
The only observed q
containment was uranium, with the Um enrichment ranging from about i
three (3) to about ten (10) percent. This report is being provided to assist you in planning for a confirmatory survey and in support of the subsequent release of the subject facilities to unrestricted use.
l GA has decontaminated equiptent and facilities consistent with the State of California's and U.S.
Nuclear Regulatory Camission's guidelines -for release of facilities and equiptent to unrestricted use.
The results of GA's final surveys (provided in the enclosed report) demonstrate compliance with these guidelines.

'.Last DeWr, GA ~ submitted a similar report and requested a confirmatory survey be performed on a group of several laboratories L
referred to as' " Group 3" in GA's Building 2 (referenced above).
It was recognized at the time that scheduling the confirmatory survey of tha ? Group 3" laboratories should be coordinated with the survey of the recently decontaminated portion of Building 9.
Now that GA has submitted the requisite final survey reports, we look forward to the confirmatory surveys being scheduled as soon as possible.
c h
While the activities and the materials used (i.e., enriched uranium)-
p in the " Hot Suite" area of Building 9 were licensed by the NRC, we are subnitting the' enclosed report to the State of Califontia Departncnt of Health Services and requesting their release of the subject area.
GA has tenants who are anxious to occupy the subject laboratories and
~
associated offices as econ as they are released.
And, GA has temporarily displaced telecmnunications personnel and equipnent until such tine as the " Hot Suite" areas are released.
Therefore, it is very inportant to GA to have the confirmatory surveys conducted expeditiously.
If you should have any questions regarding our request or the enclosed report, please contact me at (619) 455-2823.
Very truly yours, Keith E. Asmussen, Manager Licensing, Safety and Nuclear Compliance KEA/mk Enclosure-
