Dear Chairman Selin:
SUBJECT:
SUMMARY
REPORT - FORTY SIXTH MEETING OF THE ADVISORY COMMITTEE ON NUCLEAR WASTE, SEPTEMBER 22 AND 25, 1992 During the 46th meeting of the Advisory Committee on Nuclear Waste, September 22 and 25, 1992, held in Bethesda, Maryland, we discussed several matters and completed the activities noted below including the memoranda listed.
l MEMORANDA l
e Draft Regulatory Guide 8013, "ALARA Radiation Protection Procram for Effluents from Materials Facilities" (Memorandum to James M. Taylor, Executive Director for Operations, dated September 30, 1992) e frogram Plan for the Advisory Committee on Nuclear Waste l
(Memorandum to you, dated September 30, 1992)
HIGHLIGHTS OF KEY ISSUES CONSIDERED BY THE COMMITTEE Draft Reculatorv Guide 8013. " Guidance on 10 CFR Part 20 ALARA e
Radiation Protection Procram for Effluents from Materials Facilities" The Committee was briefed by the NRC staff on Draf t Regulatory Guide 8013,
" Guidance on 10 CFR Part 20 ALARA Radiation Protection Program for Effluents from Materials Facilities."
Key Committee recommendations were that the NRC staff recognize licensees' option to use the approach recommended by the International Commission on Radiological Protection, i.e.,
to use the " critical group" concept in assessing the impacts of effluent releases for the purpose of compliance with ALARA.
Furthermore, the Committee recommended that the regulatory j
guide allow an ALARA approach whereby the licensee would }

9 The Honorable Ivan Selin 2
October 16, 1992 conduct operations under a controlled regime, which would result in operational releases not exceeding a
"small fraction" of the regulatory limits set forth in 10 CFR Part 20.
Explicit limits, such as 10-20% of the Table 2 values, 4
could result in inflexible de facto regulations.
The RES staff indicated that this advice for altering the guidance would be considered to the extent that the regulations in 10 CFR Part 20 permitted.
A memorandum providing the ACNW comments was sent to the Executive Director for Operations on September 30, 1992.
ACIN Four-Month Plan The Committee prepared and approved its next four-month plan.
The plan includes a tabulation of proposed Committee activi-ties for the period October 1992 January 1993.
A memorandum, dated September 30, 1992, provided it to you.
e Carbon-14 Release Limits The Committee discussed with a member of the Environmental Protection Agency's (EPA's)
Science Advisory Board's Subcommittee on Carbon-14 its recent consideration of carbon-14 release limits contained in the EPA's Environmental Radiation Protection Standards for Management and Disposal of Spent Nuclear Fuel, High-Level and Transuranic Radioactive Wastes.
The briefing was for information only. No action was taken by the Committee.
~
Site Decommissionina Manacement Plan (SDMP) List e
The Committee was briefed by the Division of Low-Level Waste Management staff on the Site Decommissioning Management Plan, including the status of cleanup efforts to date, problems identified, and sites identified as priority sites.
This briefing was for information only.
No action was taken by the Committee.
e ACIN Future Activities i
The Committee agreed to the following tentative dates for its initial meetings in 1993:
50th ACIN Meeting January 27-28, 1993 51st ACIN Meeting February 24-25, 1993 a

October 16, 1992 Working Group Meetings Potential for the Presence of Natural Resources at a HLW Repositorv Site, October 20, 1992, St. Tropez Hotel, 455 E. Harmon Avenue, Las Vegas, NV - The Working Group will discuss methodologies for the assessment of the potential for the presence of significant natural' i
resources at the proposed high-level waste repository site at Yucca Mountain.
The relationship between future exploration for such resources and the potential for human intrusion will be emphasized.
The Impact of Lonc-Rance Climate Chance in the Area of the Southern Basin and Rance, November 18, 1992, 7920 Norfolk Avenue, Bethesda, l
MD The Working Group will discuss the significance of climate change as it may impact the performance of the proposed Yucca Mountain repository over the next 10,000 years.
Specific topics i
include data identification, acquisition and interpretations, which can be used to predict potential changes to natural conditions at the site.
Quality assurance and use of data in developing and validating computer models for predicting global and regional climate, as well as for characterizing the uncertainty in such predications will also be discussed.
Phase 2 of the HLW Iterative Performance Assessment (IPA), Dec-ember 16, 1992, 7920 Norfolk Avenue, Bethesda, MD The Working Group will be briefed by DOE representatives on the status of the DOE's Total System Performance Assessment.
The Working Group will also review the progress of Phase 2

Performance Assessment effort by NRC.
i Synercistic Data Needs for Resolvina Volcanic and Tectonic Concerns at Yucca Mountain, (Date to be determined), 7920 Norfolk Avenue, I
Bethesda, MD The Working Group will attempt to determine what data are necessary to resolve and/or move toward closure in the subject areas.
Also to be determined, is how and by whom those data will be analyzed.
