Dear Mr. Hickey:

Byletter dated March 30,1990, General Atomics (GA) submitted a plan for decommis-sioning its HTGR Fuel Fabrication Facility located in GA's SVA BuildLng (Ref.1). This plan, titled, "SVA Decommissioning plan," was revised in response to NRC comments and resubmitted on August 24,1990 (Ref. 2);.md apprc'ved in November,1990 (Ref. 3).

- Section 2.3 of the SVA Decommissioning lan defines the three categories of personnel p

who work on the SVA Decommissioning project as: 1) visitors,2) intermittent personnel, and 3) decommissioning workers.

L

~ Intermittent personnel are defined as individuals who frequent the controlled area (more than 40 hours4.62963e-4 days <br />0.0111 hours <br />6.613757e-5 weeks <br />1.522e-5 months <br /> per quarter) but who do no' work in the area. These individuals are required to take a four hour contractor radiaF safety course and pass a written exam

' with a grade of at least 70 percent. Other individuals included in this category are workers with special skills who are brought in for a specific task of less than 40 hours4.62963e-4 days <br />0.0111 hours <br />6.613757e-5 weeks <br />1.522e-5 months <br /> duration.

~ These individuals may work in the radioactively controlled ' areas under direct supervision of a qualified decommissioning. worker. They also are required to take and pass the four hour radiation safety course.

Section 3.3.2.2 of the SVA Decommissioning plan requires that decommissioning workers be observed by a health physics teci nician :o ensure that they properly. frisk l

themselves when leaving a controlled area. It further requires that visitors and intermittent -

workers be monitcred (frisked) by a health physics technician. Monitoring (frisking) will L

.indude hands, shoes,land clothing.

Mr. John W.N. Hickey, NRC June 15,1992 696 1923 Page 2 It is the requirement that intennittent workers be monitored (i.e., frisked) by a health

,hysics technician that has prompted this letter.

GA believes it is unnecessarily aurdensome on health physics techrt clan and intermittent worker resources. Accordingly, GA hereby iequests NRC approval to change the requirement so as to allow intermittent workers to monitor (frisk) themselves while under the observation of a health physics technician when leaving a controlled area, rather than have a health physics technician personally monitor them.

In terms of the SVA Deconunissioning Plan, the requested change is to revise the second paragraph of Section 3.2.2.2 which now reads (August 22,1990): "Docommissis-Ing workers will be observoct by a health physics technician to ensure that they proporly frisk when leaving a controllod ama. V:'sitors and intormittent workers will be monitored by a health physics technlclan...." to read. Instead, as follows (June 15, 1992):

• Docommissioning workers and Informittent workers will be observod by a health physics technician to ensure that they properly frisk when leaving a controlled area. Visitors will be monitored by a health physics technician...."

The justification for the requested change is: 1) all intermi ent workers are required tt to take the four hour contractor class, which includes training on how to frisk oneself, and

2) intermittent workers will be observed by a health physics technician to ensure that they are properly moni"> ring (fiisking) themselves.

Enclosed is the proposed revised Page No. 3 22 dated June 's,1992. 'ihe above requested change (addition and deletion) is indicated by shaded. type.

Upon NRC's approvel, this page would replace the earlier (August 22, 1990) vers' ion of Page 3 22 in the SVA Decommissioning Plan.

If you should have any questions regarding this request, please contact me at (619) 455 2823. Your early attention to this request will be very much appreciated.

Very truly yours, n u dA -
