SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION SUPPORTING AMENDMENT NO. 7 TO FACILITY LICENSE NO. TR-3 NATIONAL AERONAUTICS AND SPACE ADMINISTRATION PLUM BROOK TEST REACTOR DOCKET N0. 50-30
1.0 INTRODUCTION
In an amendment dated July 26, 1973, the Plum Brook Test Reactor was issued a license for Possession-Only.
By letter dated March 17, 1980, as supplemented, NASA requested authorization to dismantle both the Plum BrookTestReactor(P8TR)andPlumBrookMock-UpReactor(MUR),to dispose of the component parts and terminate License Nos, TR-3 and R-93.
Following review of the NASA applications, NRC issued an " Order Authorizing Dismantling of Facilities and Disposition of Component Parts," dated May 26,1981(i.e.,theOrdercoveredbothreactors).
By application dated July 26, 1985, NASA requested that NRC rescind the Order of May 26, 1081, and reinstate the facilities to a status of Possession-Only. NASA cited budget limitations as the reason for not being able to implement the May 26, 1981 Order.
Facility Status Both the PBTR and MUR, located at NASA's Plum Brook Facility near Sandusky, Ohio (See Figures 1 thru 3) have been shut down since January 1973. The Plum Brook Reactor is a 60 MWt light water-moderated and -cooled materials test reactor which operated from 1961 to 1973.
At shutdown in January 1973, the total integrated power was approximately 98,000 megawatt-days. License No. TR-3 was amended to Possession-Only on July 26, 1973. All fuel from the reactor was removed from the reactor site in 1973. All coolant has been drained from the reactor and Canal H.
l Multiple physical barriers have been erected and maintained to control l
access to radioactive areas.
Finally, adequate monitoring programs have been maintained since shutdown.
2.0 EVALUATION Safety Evaluations and Environmental Impact Appraisals were prepared for the reactor for the 1973 Possession-Only license amendment and the May 1981, " Order Authorizing Dismantling of Facilities and Disposition of Component Parts".

The conclusions of the earlier staff safety evaluations still are valid.
Further, in the interim period, radioactive decay has reduced residual radioactivity to levels much lower than indicated in either the 1973 Amendment SER or the 1981 Order SER.
In addition, the Technical Specifications, utilized since 1973, have been upgraded for this amendment request to reflect current NRC and ANSI recommendations.
3.0 ENVIRONMENTAL CONSIDERATION
This amendment involves changes in the installation or use of facility components located within the restricted area, as defined in 10 CFR Part 20, and changes in inspection and surveillance requirements. The staff has determined that the amendment involves no significant hazards consideration (as discussed below), there is no significant change in the types or significant increase in the amounts of any effluents that may be released offsite, and there is no significant increase in individual or cumulative occupational radiation exposure. Accordingly, this amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9).
Pursuant to 10 CFR 51.22(b), no Environmental Impact Statement or Environmental Assessment need be prepared in connection with the issuance of this amendment.
4.0 CONCLUSION
The staff concludes that amendment of this license to a Possession-Only J
status is appropriate. We have further concluded, based on the consider-ations discussed above, that:
(1) because the amendment does not involve a significant increase in the probability or consequences of an accident previously evaluated, or create the possibility of a new or different kind of accident from any accident previously evaluated, or involve a significant reduction in a margin of safety, the amendment does not involve a significant hazards consideration, (2) there is reasonable assurance that the health and safety of the public will not be endangered by the proposed activities, and (3) such activities will be conducted in compliance with tne Commission's regulations and the issuance of this amendment will not be inimical to the common defense and security or the health and safety of the public.
