1.0 BACKGROUND

Since the publication of the final recommendation of the Blue Ribbon Commission on Americas Nuclear Future in January 2012, national spent nuclear fuel (SNF) and high-level waste (HLW) geological disposal programs in countries such as Sweden, Finland, Japan, Canada, and France have continued to advance. Internationally, technical and regulatory progresses also result in the accumulation of a large amount of knowledge in design, development, implementation and regulation of deep geological repositories (DGR). In the United States, the Department of Energy (DOE) released a new waste management strategy in 2013, which endorses a system containing a pilot interim storage facility; a larger, full-scale interim storage facility; and a geologic repository.

In 2015, DOE also noted its intent to pursue separate defense and commercial HLW disposal facilities. To this date, DOE continues its generic research and development programs for a potential DGR in the future. To remain positioned to support national policy changes in areas associated with its regulatory purview, NRC staff also identified and has continued to analyze key regulatory and technical issues associated with HLW and SNF disposal in a variety of potential repository designs and geologic media.

The U.S. Nuclear Regulatory Commission (NRC) has identified actions from regulatory, environmental, and technical perspectives that will improve the ability of the Agency to quickly adapt to changes in national policy.

Because all plausible alternative scenarios for the back end of the nuclear fuel cycle produce residual waste, it is assumed that geological isolation will be a component of any new national policy. Regardless of the direction of national policy, it is imperative that NRC staff continue to stay abreast with technical and regulatory advances and with emerging issues both domestically and internationally. An awareness of international programs with similar aims in foreign countries is thus critical to support the Agencys mission under a range of potential policy outcomes.

The overarching goal of this work is to support NRCs preparations to address ongoing revisions to the U.S.

national strategy for regulating and managing nuclear wastes through the collection and analysis of technical and regulatory information produced by international programs and activities, which will then be assimilated with information obtained independently by NRC staff. A secondary goal is to use the information to continue to support NRCs development and maintenance of in-house DGR performance assessment capability to align the staffs activity to NRCs risk-informed, performance-based regulatory approach.

This task order will build on the work completed in this area in FY12 through FY19 (Task Orders 7 and 9 under contract NRC-HQ-12-C-02-0089, and Task Order 31310018F0061 under contract 31310018D0001).

2.0 OBJECTIVE

The objective of this task order is to obtain technical assistance with the identification and analysis of technical and regulatory information and strategic insights obtained from international nuclear waste disposal programs and international research and development (R&D) activities related to the management and disposal of SNF and HLW. A secondary objective is to apply key insights obtained from international SNF and HLW disposal programs and R&D to update NRCs performance assessment knowledge base, supplemented by R&D results on alternative disposal concepts from the Department of Energy.
