Douglas M.
Collins, Chief Radiological Protection and Emergency Preparedness Branch Division of Radiation Safety and Safeguards, Region II FROM:
John E.
Glenn, Chief Medical, Academic, and Commercial Use Safety Branch Division of Industrial and Medical Nuclear Safety
SUBJECT:
TECHNICAL ASSISTANCE REQUEST - ITT I am responding to your telephone request on March 18, 1992 during which you requested interpretation of Part 40 and certain decommissioning issues related to equipment with fixed contamination. We understand that the licensee, ITT, was proposing to terminate a specific license and transfer the material, e.g.,
contaminated grinder and saw, to themselves as a general licensee.
2 The maximum fixed contamination en the grinder is 15,000 dpm/100 cm 2
and 10,000 dpm/100 cm on the saw.
The equipment was to be used with a thorium oxide polishing compound containing 0.16 to 0.20 percent thorium by weight.
Presently, we understand the licensee will dispose of the grinder at an authorized burial site, use only the saw, and the polishing compound is a rare-earth compound which is exempt under 10 CFR 40.13 (c) (1) (vi).
Based on coordination with the Office of General Counsel and the Division of Low-Level Waste (Enclosure 1), we have concluded the following:
1)
ITT must decontaminate the saw to current guidelines (average 2
and maximum fixed 232Th surface contamination of 1000 dpm/100 cm 2
and 3000 dpm/100 cm, respectively).
2)
If ITT cannot achieve current guidelines, then ITT should decontaminate to an alternative level which would be "As Low As Reasonably Achievable" (ALARA).
ITT should provide a statement that this is the action they have completed and that it is ALARA.
In summary, you should have confirmation from ITT that the information we are presently assuming is correct, and have ITT confirm that they have decontaminated the saw to current guidelines for release to unrestricted use, or ALARA for transfer to a general license.
