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:
-
The technical, policy, and societal objectives and risks for developing a staged repository system.
-
Potential impacts of staging on pre- and post-closure safety and security as well as cost, public acceptance, and repository operations.
-
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.
-
Identification of knowledge gaps that should be addressed to improve design, monitoring, and performance confirmation capabilities.
-
Identification of potential incompatibilities of a staged repository system with licensing procedures, and strategies for resolving them.
