July 16, 2004 Dr. B. John Garrick, Chairman Advisory Committee on Nuclear Waste U.S. Nuclear Regulatory Commission Washington, D.C. 20555

SUBJECT:

DECOMMISSIONING THE WEST VALLEY SITE AND THE APPLICATION OF PERFORMANCE ASSESSMENT TO DEMONSTRATE COMPLIANCE WITH THE LICENSE TERMINATION RULE

Dear Dr. Garrick:

I am responding to your June 9, 2004, letter to the Chairman. In that letter you provided the views of the Advisory Committee on Nuclear Waste (hereafter, the Committee) on the decommissioning of the West Valley site and the application of performance assessment (PA) to demonstrate compliance with the License Termination Rule (LTR). In particular, the Committee offered general observations and conveyed a specific recommendation.

We appreciate the Committees thoughtful observation regarding factors contributing to the complexities of the West Valley site and use of PA in demonstrating compliance with the LTR.

We agree that PA will serve as the technical basis for actions proposed in the U.S. Department of Energys (DOEs) Decommissioning Plan (DP) and Decommissioning Environmental Impact Statement (EIS), and that producing the PA models and writing the DP and EIS will be an iterative process. Although details of the PA are still developing, the Committee was informed that DOE intends to mix deterministic, bounding, and probabilistic analyses in various parts of the assessment. The Committee also is aware of the staffs intent to develop an independent PA model for the West Valley site, and that this model will be probabilistic in nature and use realistic assumptions. We appreciate the Committees strong support for the staffs efforts to develop an independent PA model to inform our review and facilitate confirmatory analyses of DOEs PA results.

The Committee believes the Commission and staff should encourage DOE to use a risk-informed approach in the PA to the extent practical. We agree with the Committees recommendation and will continue to encourage DOE to use a risk-informed approach in the PA. This recommendation is consistent with the U.S. Nuclear Regulatory Commissions consolidated decommissioning guidance (NUREG-1757); the PA methodology for low-level waste disposal facilities (NUREG-1573); and the LTR analysis recently approved by the Commission.

Collectively, this guidance promotes realism, adequate consideration of uncertainty, and probabilistic analyses. If the analyses are deterministic, they should include numerous sensitivity and uncertainty analyses.

B. J. Garrick 2 We understand that the Committee intends to meet with representatives of the DOE West Valley staff, the New York State Energy Research and Development Authority, and other stakeholders in the future to obtain their perspectives on the decommissioning plans for the West Valley site. We would be pleased to provide the Committee with contacts to help facilitate such meetings.

In summary, we appreciate the Committees observations and recommendations related to decommissioning of the West Valley site and the role of the PA in that important effort. We will continue to keep the Committee informed of staffs effort to develop an independent PA and other decommissioning issues.

Sincerely,

/RA/
