STATEMENT OF TASK

The National Research Council will provide recommendations on the design and operational strategies for a staged geologic repository. These recommendations should address the following points in a generic sense, with applications to the Yucca Mountain program where appropriate:

  1. The technical, policy, and societal objectives and risks for developing a staged repository system.

  2. Potential impacts of staging on pre- and post-closure safety and security as well as cost, public acceptance, and repository operations.

  3. Strategies for developing a staged repository system, including design strategies; strategies for constructing, filling, and closing a staged repository; monitoring strategies to confirm repository performance during pre- and post-closure phases, including a consideration of what should be monitored and confirmed.

  4. Identification of knowledge gaps that should be addressed to improve design, monitoring, and performance confirmation capabilities.

  5. Identification of potential incompatibilities of a staged repository system with licensing procedures, and strategies for resolving them.
