53rd ACNW Meeting 2
May 19-20, 1993 are enumerated in the transcript of the meeting session.
The Committee prepared and issued a report as noted above.
J 3.
Standard Review Plan for the Review of Remedial Action of Inactive Mill Tailinas Sites j
l The Committee reviewed and was briefed by the NRC staff on Revision 1 of the Standard Review Plan for the Review of Remedial Action of Inactive Mill Tailings Sites Under Title I of the Uranium Mill Tailings Radiation Control Act.
1 The Committee was favorably impressed with the plan. Although the members suggested several detailed revisions to the Standard Review Plan for the NMSS staff's consideration, all were minor in nature.
These recommendations are-contained in the meeting transcript.
The Committee prepared and issued a l
report as noted above.
4.
NRC Staff's Review Plan for DOE Study Plans The Committee was briefed by a representative of the NRC staff on the NRC Review Plan, Revision 2, for the DOE Study Plans.
The Committee was also briefed by a representative of the Yucca Mountain ite Characterization Project, DOE, on the current status or the DOE Study Plans. The content and format specified uy tM Level of Detail Agreement between NRC and DOE were explained during the briefing.
This briefing was for information only.
No Committee action was taken as a result of this briefing.
5.
DOE Site Characterization Proaress Reports The Committee was briefed by a representative of the NRC staf f on NRC's responses and follow-up to the DOE Site Character-ization Progress Reports for the proposed Yucca Mountain repository.
The Committee was briefed by a representative of the Yucca Mountain-Site Characterization Project, DOE, on the current status of the Progress Reports and how DOE handles NRC's comments.
This briefing was for information only.
No Committee action was taken as a result of this briefing.

[Mr.
Giorgio Gnugnoli has the follow-up action on this item.]
The Committee agreed to hold an administrative meeting in e
August to review the future role and goals of the Committee.
The session will be in lieu of the regularly scheduled Committee meeting on August 25-26, 1993. A l
proposed agenda and list of questions will be prepared and distributed to the ACNW members for comment.
A site close to the One White Flint North Building will be i
selected for the meeting. The members expressed interest in meeting with the Commissioners during the session.
The Committee agreed to have a technical exchange meeting with the Yucca Mountain Project Office in Las Vegas, Nevada, on October 27-28, 1993. This meeting, along with a site visit to Yucca Mountain, will be in lieu of a full Committee meeting in October.
Dr.
Hinze recommended that, in conjunction with this trip, a working group meeting be held in Las Vegas on the characterization of the unsaturated zone flow and transport properties in conjunction with the other activities in Las Vegas.
Dr. Pomeroy noted that he has a conflict on September 22-23, 1993. The Committee agreed to reschedule the Commit-tee meeting for September 29-30, 1993.
The Committee agreed to postpone a planned briefing on e
performance assessment computer codes for site cleanups, such as DITTY and GENII, until the NRC staff's plan for code use becomes more evident.
The Committee agreed to postpone a planned briefing on the status of the Licensing Support System until DOE and NRC plans are further developed.
The Committee requested a briefing from representatives e
of the NRC and U.S. Geological Survey on thermal loading uncertainties and rock-water interactions.
Dr. Moeller reminded the Committee of his interest in scheduling a working group meeting that will examine lessons learned from both HLW and LLW facility siting and operational experiences. The working group will focus on technical and regulatory deficiencies. Planning for this meeting will be deferred until the Committee has identi-fied areas of high priority during the August administra-tive session.
