Dear Dr. Remley:
By application dated March 10, 1980 you requested authorization to dismantle your L-85 reactor and terminate license No. R-ll8'.
Recently you contacted Mr. Erickson of my staff with respect to our interpretation of certain surveillance requirements in your Technical Specifications (TSs) that required operation of the L-85 reactor to perform the surveillance.
In your discussion you stated that, since Rockwell did not intend.o operate the reactor again, it would not be prudent to perform any unnecessary surveillance tests which would cause any further buildup of fission and activation products in the reactor.
We agree that further operation of the reactor to perform the surveillance tests of TSs 4.lb, 4.lc, 4.2d(1) and 4.2d(3) is not desirable in view of your plans to dismantle.
In addition, we interpret the surveillance requirements of the above TSs to be a limiting conditions for operation.
Therefore, if you do not perform these surveillance tests in the time intervals specified, the reactor may not be brought critical or operated until specific authorization has been obtained from the NRC. Also, Rockwell would not be in violation of the TSs if the surveillance specified in TSs 4.lb, 4.lc, 4.2d(l) and 4.2d(3) is not done as long as the reactor is not brought critical or operated.
With respect to your dismantling plan, Enclosure #1 specifies Radiation Levels Acceptable for Release of Reactor Facility to Unrestricted Access.
Your " Contamination Limits" ii; your March 10, 1980 submittal are acceptable for surface contamination. You should, however, add limits for Radioactive Material other than Surface Contamination that are consistent with Enclosure #1.
Sincerely, 3,-

Enclosure RADIATION LEVELS FOR RELEASE OF REACTOR FACILITY TO UNRESTRICTED ACCESS Surface Contamination Surfaces must be decontaminated to levels consistent with Table 1 of Reg. Guide 1.86.
Radioactive Faterial Other Than Surface Contamination (Co 60. Eu 152, Cs 137)
Co 60 Eu 152 and Cs 137 that may exist in concrete, components, structures, and soil must be removed such that the radiation levg}
from these isotopes is less than SuR/hr above natural background'/
l as measured at one meter from surface.
General Site survey procedures acceptable to the NRC must be used.
I) Radiation from naturally occurring radioisotopes as measured at a comparaole uncontaminated structure or exterior soil surface.
