Subject:
Modification In Rocketdyne Radiological Environmental Monitoring
Dear Mr. Haughney:
The recent Rocketdyne application for renewal of the U.
S.
NRC Special Nuclear Materials License No. SNM-21 requests a possession limit of 6g of plutonium for research and development purposes.
- /his reflects the termination of reactor fuel decladding operations at the Rockwell International Hot Laboratory (RIHL, Building T020 at the Santa Susana Field Laboratories (SSFL)), and is a significant decrease from the previous possession limit of 2000g of plutonium or 5000g of uranium-23 5, or formula combinations of the two not exceeding 5000 formula grams.
(A request will be submitted to the State of California L
Department of Health Services, Radiologic Health Branch -
Licensing, requesting deletion f rom our Radioactive Materials License No. 0015-70, of the subitems that were relevant to the fuel decladding operations.)
l In view of this major reduction in nuclear and radiological operations at SSPL, and recognizing that there has been no
\\
significant dispersable radioactive material in the RIHL
)
since completion of the Fermi fuel disassembly project in 1987, it is. appropriate to modify our radiological environ-mental monitoring program to respond to these conditions.
The reductions in this program will be accompanied by an increase in focus on the few remaining facilities and areas at SSFL that have residual radioactive contamination.

i Routine sampling and analysis of environmental soil, air, and vegetation will be discontinued.
In place of these, sampling will be done in conjunction with monitoring and I
decontamination operations at the following specific f acilities or areas at SSFL:
1.
Rockwell International Hot Laboratory 2.
Building T059 decontamination project 3.
Radioactive Materials Disposal Facility 4.
T886 Sodium Burn Pit 5.
T005 Uranium Carbide Pilot Plant 6.
T023 laboratory 7.
T064 storage vault 8
T009 High Energy-Rate Forging laboratory and In-Service Inspection laboratory This monitoring will-include sampling and analysis of air, soil, water,. vegetation, effluents, and radiation as indicated by the situation and operations.
Routine sampling and analysis of surf ace and groundwater not related to these areas will continue by use of independent laboratories.
These changes are being implemented to be effective in calendar year 1990.
Future annual reports on environmental monitoring will include appropriate discussion of the radiological measurements but will show a greater emphasis on the conventional impacts on the environment.
