\...../ Environmental Assessment Dismantling of Facility and Disposition of Component Parts - Phase I for the University of California at Los Angeles Argonaut Reactor Docket No. 50-142 I. Description of Proposed Action ,

By application dated October 29, 1985, as supplemented, the University of California at Los Angeles (UCLA) requested authorization for Phase I of a multi-phase decontamination and dismantling program for their Argonaut reactor located on the UCLA campus in Los Angeles. Phase I of the Plan consists of the removal of the moveable components within the biological shielding which will permit access to the core for a subsequent radiological survey of the activation level of the biological shielding and foundation.

Following the analysis of the survey results, alternatives for the sub-sequent phase (s) of the decommissioning plan will be developed by UCLA.

UCLA will then request an additional Order to fulfill the preferred f alternative plan for deconsnissioning.

II. Need for Proposed Action By an Order issued by the Atomic Safety and Licensing Board, dated November 8, 1985, UCLA must dismantle the reactor by September 30, 1989 except for the biological shield and certain other components described in a stipulation among the parties.

UCLA has indicated that a final disposition of the biological shielding cannot be determined until the biological shielding can be surveyed without

- the interference presented by the numerous radioactive components now residing in the core. Following removal of these components and the radiation survey, the subsequent phases for the deconsnissioning of the reactor facility will be detennined.

III. Alternatives to the Proposed Action l

An alternative to the proposed dismantlement of the reactor would be entombment of the reactor. This alternative would, however, prevent use of the reactor room for other purposes by the University due to the I radioactivity of internal reactor components and would not constitute an environmentally preferable alternative due to retention of radioactive components on site.

l IV. Environmental Impact of Dismantling and Decontamination All decontamination will be conducted by trained personnel according to

! previously reviewed procedures and will be overseen by experienced health physics staff. Solid and liquid wastes will be removed from the facility and managed similarly to other radwaste generated in other UCLA facilities.

UCLA has calculated that the collective dose equivalent for workers for l

Phase I of the project will not exceed 10 person-rem.

Based on the review of the specific proposed activities associated with j the Phase I dismantling and decontamination of the UCLA facility, the

staff has determined that there will be no significant increase in the

' amounts of effluents that may be released offsite, and no significant ir. crease in individual or cumulative occupational or population radiation exposure, and that the result of the dismantlement action will decrease the amount of radioactive contamination in the reactor building. -

V. Agencies Contacted: None.

VI. Conclusion i Based on the foregoing considerations, the staff has concluded that there i

will be no significant environmental impact attributable to this proposed activity. Having reached this conclusion, the staff has further concluded that no Environmental Impact Statement for the proposed action need be prepared and that a No Significant Environmental Impact Finding is appropriate.
