Join us for a virtual event featuring a discussion on a new set of recommendations from the ANS Special Committee on Generic Standards for Disposal of High-Level Radioactive Waste. The Special Committee developed a set of recommendations and observations on postclosure generic disposal standards that are protective of public health, safety, and the environment; consistent with international best practices; and implementable through established licensing processes. The Special Committee plans to finalize the report later in 2023, after consideration of stakeholder input.
