- p. Hann K. Apogino J. Singleton L. Nielson D. Gillen G. L<ndsey B. Hughes-M. Thomas T. Johnson R. Bennett W. Lin A. Fan D. Metzler S. Wastler F. Titus Discussion:
On the. morning of June 13, 1990, the NRC staff visited the Lowman UMTRA site at Lowman, Idaho. During the trip to the site, where possible, the NRC technical staff began informal discussions on their review of the RAS with their technical counterparts from the TAC, RAC, and/or D0E. Once at the site, the NRC staff, with their technical counterparts, traversed the sitet discussed their technical connents informally; and/or confirmed specific site information related to NRC's consnents.
A. fan and D. Metzler traversed the site discussing the groundwater at the Lowman site.
HRC concerns in this technical area focus on the characterization of the bckground and on-site groundwater and pore water quality, and the QA/QC procedures of the water chemistry data. The TAC provided a sunenary of the
.owman hydrogeologic characterization program for June,1990 which was developed to provide additional information and data that are pertinent to DOE's groundwater protection strategy and that are applicable to NRC conaents.
T. Johnson, G. Lindsey, W.Lin R. Bennett and P. Hann investigated Lownan site features that would impact the site design with regard to surface water hydrology and erosion protection. Of particular interest was the steep northern slope of the site and the potential for gully erosion.
A large gully.
was found and investigated on the site that would directly impact the erosion protection design, but the DOE and the RAC indicated that the gully was probably man-made and probably one of the only gullies in the entire area.
Investigations of the steep slope also led to discussions of the apron design, riprap size, and rock quarry locations.
4 i
D. Gillen also spent the morning independently traversing the steep northern i
slepe and the river escarpment south of the proposed disposal site, investigating soil types and depths in regards to verifying slope stability.
As questions arose, individual TAC, RAC or DOE personnel were sought for consultation.
In the area of geology the concerns were related to the regional seistnic and t
tectonic characterization of the site rather than the Lowman site geology.
Therefore, the site visit was for site f amiliarization and observation, in addition, K. Agogino, TAC site manager and I, as NRC project manager, traversed the site interacting with the above NRC staff and DOE, TAC and RAC personnel to facilitate the exchange of technical information.
In mid-af ternoon, we lef t the site to return to Boise where we held a meeting to review the NRC staf f concents. The NRC began this meeting by reiterating that our comments were informal, preliminary, and not all-inclusive. Therefore, the NRC did not expect DOE to provide formal responses; however, we indicated that DOE should take the connents into consideration in preparing the final rap for NRC review.
in general, the purpose of the meeting was to assure that DOE TAC and RAC clearly understood the connents of the NRC technical staff pre,sent, to discuss any changes to the NRC comments as a result of information gathered on site, to present additional concents in the areas of soil cleanup and radon barrier design and to f acilitate open disussion.
The NRC staff indicated that if additional questions arose concerning our connents, DOE should feel free to contact the specific NRC technical reviewer for additional information. The open discussion centered on NRC concerns with the cell design shown in the RAS.
DOE indicated that the call design in the RAS is under revision and the pros and cons of the possible changes to the cell design was discussed.
NRC staff reviewers indicated that the site visit and nieeting concept, as developed in the streamlining agreement, is very helpful. We indicated that this type of review procedure is beneficial to all parties, particularly in providing early coments from the NRC to DOE if problera areas are identified.
