Title: Acceptance for Referencing, RADMAN Topical Report

(WMG-102, as Revised from WMG-101P)

See the letter from L. B. Higginbotham to P.T. Tuite (Waste

Management Group, Inc.) dated July 25, 1983. The NRC

reviewed the Waste Management Group (WMG) Topical Report on

the RADMAN computer code which is a series of routines that

can be used by radioactive waste generators to characterize

packaged waste; classify waste packages by Part 61 waste

classification requirements; and prepare documentation

required by 10 CFR Part 61, Department of Transportation

(DOT) regulations and license conditions at existing

low-level waste disposal sites. This health physics

position was written in the context of 10 CFR 20.311, but

it also applies to "new" 10 CFR 20.2006.

The RADMAN code operates on a waste stream characteristics

data base that is specific to the types and forms of waste

generated by individual facilities, as well as to the

facility- and waste stream-specific distributions of

radionuclides and chemical agents. Based on WMG submittals

and after NRC review, RADMAN code provides an acceptable

vehicle which can be used by licensees as part of

compliance with the requirements in 10 CFR 20.311 [or, at

present, 10 CFR 20.2006] and with 10 CFR 61.55. This

conclusion is predicated on completion of the final Topical

Report according to the review assignments and upon the

following four conditions:

1. That radionuclide correlations are undated on a

waste stream, plant, or generic basis as additional

sampling data becomes available. The NRC staff believe

that many correlations currently assumed in RADMAN between

Co-60 and activation products, and between Cs-137 and

fission products may not be valid. The current lack of

sampling data, however, precludes established verified

correlations at this time in RADMAN for a number of

radionuclides of interest.

2. That the manifest formatting provisions of RADMAN

are updated to include all of the information required in

10 CFR 20.311 [or 10 CFR 20.2006] when revised manifest

forms are made available by disposal site operators.

3. That RADMAN is appropriately updated as State

(South Carolina, Washington, Nevada) provisions for

compliance with 10 CFR Part 61 waste classification and

manifesting requirements are made available.

4. That RADMAN is updated as required to remain

consistent with future modifications to NRC, DOT, State or

other regulatory requirements as such requirements becomes

effective, as well as changes to disposal site license


Should NRC criteria or regulations change such that our

conclusions as to the acceptability of the Topical Report

are invalidated, WMG, and/or applicants referencing the

Topical Report, will be expected to revise or resubmit

their respective documentation or submit justification for

the continued effective applicability of the Topical Report

without revision of their respective documentation.
