SUBJECT:
EVALUATION OF THE PROPOSED RESEARCH PROGRAM - GENERIC,"
h, ' y &j.
ASSESSHENT OF TMI-2 CONTAMINATION DISTRIBUTION AND M'Y DECONTAMINATION EFFECTIVENESS In Yesponseito your request, we have evaluated the proposed research program
+
(see Enclosure 1) entitled, " Generic Assessment of TMI-2 Contamination Distribution and Decontaination Effectiveness." In our evaluation, we have considered (1)' the need for the program in tems of its generic value as well as its benefit to the TMI-2 cleanup (2) the involvement of other members i
(e.g., the' Department of Energy) of the four party organization (GEND) which uns establ(shed to coordinate THI-2 data gathering activities, (3) the scope of work of the proposed program, including the division.of responsibilities between program participants U.e., the NRC and DOE), and (4) the level of funding for-the portion of the proi, cam to be sponsored by the NRC.
Regarding the need for the proposed research program, we believe the program has significant merit. primarily for its generic value. The objectives of this program are t's characterize (i.e., detemine type, intensity, energy spectrum, etc.) the radiation fields within the containment building, deter-mine the relative distribution of radioactivity and the influence of design.
layout and configuration on this distribution, and determine the decontamination effectiveness of various decontamination techniques (e.g., the use of high and low pressuru sarays, chemical cleaning solutions, mechanical scrubbers, etc.)
j
,) on a variety o!' surfaces (e.g., metal, concrete, p inted, etc.).
The infomation 6~
7 9athered from this program can be utilized to facilitate future containment com-ponent configuration and design and detemine appropriate methods of decontami-
..T nation for facilities which have been exposed to a large scale contaminating event or facilities which require decontamination as.w iated with decommissioning.
.'Although, we chnsider the benefit from the program 12 be primarily. generic in
~
nature, a secondary benefit will be the feedback of information regarding decon-tamination effectiveness to the remaining decontamination activities at TMI.
It should be noted that the philosophy governing the extent of decontamination in the TMI-2 contiinment building is to perfom only those decontamination 1
activities which are necessary to support defueling the core. This'means that

Hamid R. Denton aW the initialJdecontamination efforts may be limited to a single washdown, if L
it proves to be sufficiently effective, and that many areas of the building 1
will not be' decontaminated until after tho' defueling. Thus, there is the
. opportunity for the results of the research program to be applied to future
- 'TMI-2 cleanup activities?
In order to avoid any potential conflict, of interest regarding the scope of S,
work in the msearch program (i.e., conf 31 cts related to funding and sponsoring activities within the containment buildin,1 while, at the same time, regulating those activities), we initiated discussions with the on-site DOE Technical 4
Integration Office (TIO) to seek DOE spcnstrship of portions (i.e., the on-site c
work) of the proposed program. The TIO was established to coordinate the implementation of the data gathering programs" recommended by the GEND. The TIO agreed to sponsor (ano fund) all the on-site work (e.g., sampling, radiation mapping, etc.) related to the program and we would spons;r and fund all the
- off-site work (e.g., sample anelysis, data reduction, report writing, etc.)
related to the program. We support this dual program (COE and NRC) approach
~
and propose the delineation of responsioilities and scope of work as described in Enclosure 2.
As noted in Enclosure 2, the NRC portion of the proposed program will require funding of approximately $80,000 which is less than half of the estimated l
costs in the. original program prop (osal (Enclosure 1).see Enclosure 3) requires tha It should be noted that the Joint Coordination Agreement sponsored by the Government shall be contrrcted for by the TIO. This adminis-trative arrangement will help to ensure that there is no duplication of effort related to proposed research programs, In sunnery, we recommend that a User Request foi funding be forwarded to the t
Office of Nuclear Regulatory Research for the program described in Enclosure 2.
