Workshop on Performance Assessments of Near-Surface Disposal Facilities: FEPs Analysis, Scenario and Conceptual Model Development, and Code Selection
AGENCY: Nuclear Regulatory Commission.
ACTION: Public meeting.
-----------------------------------------------------------------------
SUMMARY: The U.S. Nuclear Regulatory Commission (NRC or the Commission) plans to conduct a workshop on performance assessments of near-surface low-level radioactive waste (LLW) disposal facilities. The workshop has been developed to facilitate communication among Federal and State agencies, industry representatives, contractors, and members of the public on three aspects of a performance assessment: (1) Features, Events, and Processes (FEPs) analysis, (2) the development of scenarios and conceptual models, and (3) the selection of computer codes. Information gathered from invited subject matter experts, stakeholders, and other interested members of the public will be used to improve guidance on performance assessments for near-surface disposal of LLW.
DATES: The workshop will be held on August 29 and August 30, 2012.
ADDRESSES: The public meeting will be held (registration begins at 7:30 a.m.) at the NRC Auditorium, 11545 Rockville Pike, Rockville, Maryland 20852. The NRC welcomes active participation from those attending. Members of the public will be able to participate via telephone and webinar. The telephone and webinar information is provided below.

Background
The Commission's licensing requirements for the disposal of LLW in near-surface approximately the uppermost 30 meters (100 feet) facilities reside in Title 10 of the Code of Federal Regulations (10 CFR) Part 61, ``Licensing Requirements for Land Disposal of Radioactive Waste.'' These regulations were published in the Federal Register on December 27, 1982 (47 FR 57446). The regulations emphasize an integrated systems approach to the disposal of commercial LLW, including site selection, disposal facility design and operation, minimum waste form requirements, and disposal facility closure. In connection with demonstrating compliance with 10 CFR Part 61, a performance assessment is used to quantitatively evaluate potential releases into the environment and the resultant radiological doses. NRC guidance for developing performance assessments can be found in NUREG-
1573. Currently, the NRC is considering a revision to 10 CFR Part 61.\1\

NRC Public Meeting
The purpose of this public meeting is to facilitate communication and gather information from Federal and State agencies, industry representatives, contractors, and members of the public concerning performance assessments of near-surface disposal facilities. Stakeholders and other interested members of the public will have an opportunity to pose questions directly to presenters and panelists in each of the sessions. Information gathered in the meeting will be used to improve guidance on performance assessments for near-surface disposal of LLW. The workshop will be organized into four sessions comprising a series of presentations followed by panel discussions of invited subject matter experts. The workshop sessions are as follows:
Session 1: Performance Assessment Overview: US and International Approaches to Performance Assessment and Experiences with Analyses for LLW
Session 2: Analysis of FEPs for Near-Surface Disposal Facilities
Session 3: Scenario and Conceptual Model Development
Session 4: Code Selection and Implementation, Model Abstraction, and Confidence Building Activities
The public meeting will be held on August 29 and August 30, 2012, from 8:00 a.m. to 5:00 p.m. (registration begins at 7:30 a.m.) in the Auditorium on Level P1 at NRC Headquarters, 11545 Rockville Pike, Rockville, Maryland 20852. Pre-registration for this meeting
