I am looking for publications
discussing the development of 10 CFR 61 scaling factors for decommissioning
sites that are being dismantled 20 years after the termination of operating the
nuclear reactor. I have the NRC Branch Technical Positions (1983 and
1995) discussing classification of wastes. I am familiar with 10 CFR Parts
20 and 49 CFR for manifesting of wastes, and 10 CFR 61 concerning proper
classification of wastes.
Specifically, I am looking for information
on how to properly scale transuranic radionuclides. For an operating
facility, transuranic radionuclides are traditionally scaled from Ce-144
(radioactive half-life of 284 days). 20 years after the operation of the
nuclear reactor, Ce-144 has undergone decay of more than 20
half-lives. Therefore, I don't think it is appropriate to use Ce-144 to
scale other radionuclides.
Prior to discussing this issue with
regulators or disposal sites, I would like some information from personnel
working at decommissioning sites or with people that have experience
in this matter.
Any personal operating experience or
knowledge of publications is appreciated.
