The IGSC provides advice to the RWMC on major and emerging issues to facilitate the development of waste management strategies at national and international levels and to enable the management of radioactive waste and materials to benefit from progress of scientific and technical knowledge. In particular, the IGSC:



In undertaking its mission, the IGSC will:

  1. Define, oversee and carry out a work programme of technical activities related to the development, evaluation and communication of safety cases in different stages of repository programmes as a basis for confidence and decision-making pertaining to the development of geological disposal facilities for long-lived radioactive waste. Emphasis is on the identification and resolution of issues; the development of knowledge, approaches, methods and technical tools for which there is interest of member countries on safety case development; and publication of findings where appropriate.

  2. Facilitate communication and information exchange between IGSC members to promote frank interchange between peers. In particular, the IGSC provides a neutral forum for discussion with a view to identifying emerging issues and trends, reviewing the state-of-the-art and promoting further understanding and developing common views, including the development of tools and methods.

  3. Promote the exchange of information and strive for common understanding, shared approaches and methods for the development, documentation and evaluation of safety cases by the operator, regulator and research and development organisations. Emphasis is on strategic and methodological issues.

  4. Cooperate and collaborate with other NEA and international groups on the various issues of safety case development and communication. In particular, collaborate on approaches to increase stakeholder confidence in the safety case (Safety Case Communication).  If there are common needs and interest, collaborate to share deep geological repository (DGR) safety case experience with NEA groups working on the safety of other disposal facilities (for example near-surface facilities).

  5. Interface with other international bodies, in particular the IAEA and European Commission, to ensure appropriate synergy and collaboration and to avoid duplication of effort.
