NUCLEAR REGULATORY COMMISSION
 

LLW Performance Assessment Workshop

AGENCY: Nuclear Regulatory Commission.

ACTION: Notice of Workshop.

-----------------------------------------------------------------------

SUMMARY: The Nuclear Regulatory Commission (NRC) staff plans to conduct 
a Low-Level Radioactive Waste (LLW) Performance Assessment Workshop to 
provide opportunity to comment on and discuss NRC's Draft Branch 
Technical Position (BTP) on Performance Assessment for LLW Disposal 
Facilities and Development of NRC's Test Case Simulations. The workshop 
is jointly sponsored by NRC's Division of Waste Management and Office 
of State Programs in cooperation with the Host State Technical 
Coordinating Committee and the E-5 Committee of the Conference of 
Radiation Control Program Directors, Inc. Participants include State 
regulators, State authorities and developers, the Environmental 
Protection Agency and the U.S. Department of Energy. Members of the 
public attending will have opportunity to offer comments and 
participate in discussions.

DATES: The workshop will take place from 8:00 a.m., Wednesday, November 
16, 1994, and conclude at 4:30 p.m. on Thursday, November 17, 1994.

LOCATION: The workshop will be held at NRC's Auditorium, Two White 
Flint North, 11545 Rockville Pike, MD 20852. Parking is limited. The 
White Flint Metro stop is within one block.

CONTACT: For further information, contact Dr. Stephen N. Salomon, 
Office of State Programs, U.S. Nuclear Regulatory Commission, 
Washington, D.C. 20555, Telephone (301) 504-2368; FAX (301) 504-3502; 
or INTERNET: SNSNRC.GOV.

SUPPLEMENTARY INFORMATION: The NRC staff published in January 1994 a 
draft BTP on Performance Assessment for LLW Disposal Facilities and 
copies were distributed for review by Agreement States. The BTP was 
based on the U.S. Code of Federal Regulations, Title 10, Chapter 1, 
Part 61 ``Licensing Requirement for Land Disposal of Radioactive 
Waste,'' (Part 61) that specifies license requirements and performance 
objectives for LLW disposal facilities. The guidance objective of the 
BTP is to provide license applicants, licensees, States and compacts, 
and the NRC staff with an acceptable strategy and methodology for 
performing the technical analysis required to demonstrate compliance, 
in the post-closure time frame, with the performance objective in Part 
61, governing radiological protection of the public health and safety 
and the environment. Participants in this workshop will discuss 
regulatory and technical issues in the draft BTP and the development of 
NRC's test case simulations Also, State regulatory and technical issues 
will be discussed. To achieve a more successful workshop, participants 
are encouraged to read the BTP before attending the workshop. Copies 
can be obtained from Dr. Salomon.
    The proposed agenda identifies the following discussion topics for 
the morning of November 16: The Purposes and Goals of the LLW PA 
Workshop, Overview of the BTP, Overview of PA Modeling Technical Issues 
and Recommended Analytical Approaches, Open Discussion of Iterative PA 
Process, Overview of PA Modeling Technical Issues and Recommended 
Analytical Approaches, Open Discussion of Technical Issues, and 
Environmental Protection Agency draft LLW Standard, 40 CFR 193. In the 
afternoon, there will be sessions on Overview of Comments on 
Preliminary draft of BTP and Revisions, Discussions of Regulatory and 
Technical Issues in LLW PA [Treatment of Engineered Barriers; Role of 
Site-Scenarios, Conceptual Models, and Data Needs; Uncertainty/
Sensitivity in Regulatory Decision Making; Timeframe for PA Analysis; 
and Role of Performance Assessment in Demonstrating Compliance]. The 
afternoon shows Panel Discussions of Regulatory and Technical Issues in 
LLW PA.
    On November 17 in the morning, sessions include the NLLWMP 
technical assistance and computer modeling capability, Overview of NRC 
Staff LLWPA Modeling Efforts [Description of Test Case and Integrated 
Systems Model, Hardware/Software Requirements for LLWPA, Documenting 
Results, Test Case Results and Discussions of Important Conclusions, 
and Lessons Learned from Test case], PA Methodology Status Update, 
Panel discussion with State regulators and develops [Infiltration, 
Engineered Barriers, Source Term, Ground Water Transport and 
Dosimetry], and DOE approach to LLW PA Modeling.
    The afternoon includes Breakout sessions on Key Technical Issues in 
Implementing the BTP [Infiltration, Source Term, Offsite transport and 
dose, and Aspects of computer modeling], and Reports of Breakout chairs 
on issues and approaches discussed. The Workshop will end with a Wrap 
Up, Conclusions and Summary session.
    The workshop is a public meeting and members of the public 
attending will have opportunity to offer comments and participate in 
discussions. A transcript of the workshop will be available for 
inspection and copying for a fee, at the NRC Public Document Room, 2120 
L Street, N.W. (Lower Level), Washington, D.C. 20555.

    Dated at Rockville, Maryland this 12th day of October, 1994.
