In the 1990s the U.S. Department of Energy (DOE) completed a number of system analyses investigating consolidated interim storage as a part of the waste management solution. These analyses are “dated” and do not reflect the present situation regarding at-reactor used nuclear fuel (UNF) management, alternatives for away from reactor management of used nuclear fuel, and alternatives for the ultimate disposal of UNF.

The Department of Energy (DOE) issued its Strategy for the Management and Disposition of Used
Nuclear Fuel and High-Level Radioactive Waste in January 2013. DOE undertook studies and analyses
to determine systems and design concepts as a preliminary step to further defining systems, equipment,
and facilities to implement the Strategy. This report uses the work performed by industry and national
laboratories and configures system components to meet the requirements of the Strategy. The project

1.0 INTRODUCTION

Under a contract with the Department of Energy (DOE), the AREVA Team has evaluated the alternatives for developing a used nuclear fuel (UNF) Consolidated Storage Facility (CSF) for UNF from US reactor plants. The study, based upon specific criteria and requirements for the US, considered numerous credible storage options and selected the one that met the needs of the country. For this task, the AREVA Team comprises AREVA, URS, Duke Energy, Dominion, and Coghill Communications, Inc.

1.1 Purpose

The “Strategy for the Management and Disposal of Used Nuclear Fuel and High-Level Radioactive Waste” report was issued by the Department of Energy (DOE) in January 2013. The strategy includes a phased, adaptive, and consent based approach to siting and implementing a comprehensive management and disposal system. It also endorses a waste management system containing a pilot interim storage facility and a full-scale interim storage facility, which prioritizes the acceptance of fuel from shut-down reactors. Required features of the system and facilities are:

This report has been prepared by the industry team of Shaw Environmental & Infrastructure,
Inc. (Shaw) and Longenecker & Associates (L&A) in response to the Department of Energy
(DOE) Statement of Work, “Development of Consolidated Storage Facility Design
Concepts,” indefinite delivery/indefinite quantity Task Order No. 11, as specified by the
DOE’s Office of Nuclear Energy.

This report documents the concepts, feasibility, advantages, disadvantages and recommendations for STAD canister systems developed by EnergySolutions and its team of partners: NAC International, Talisman International, Booz Allen Hamilton, TerranearPMC, Exelon Nuclear Partners and Sargent & Lundy, hereafter referred to as “the Team”.

Under Task Order 17 of the industry Advisory and Assistance Contract to the Department of
Energy (DOE) DE-NE0000291, the AREVA Team has provided a conceptual design for a
reusable transportation cask (the 6625B-HB) capable of transporting BWR and PWR used
nuclear fuel (UNF) assemblies, including high burnup UNF. These assemblies can be shipped
either as bare fuel or fuel loaded into damaged fuel canisters (DFCs). The 6625B-HB cask has
been designed with reasonable assurance it can be licensed by the Nuclear Regulatory

Per the requirements of the Task Order 21: Operational Requirements for Standardized Dry Fuel Canister Systems, Statement of Work (SOW), EnergySolutions and its team partners: NAC International, Booz Allen Hamilton and Exelon Nuclear Partners, hereafter referred to as “the Team”, is providing for the U.S. Department of Energy (DOE) an Updated Final Report, which documents the results from the studies performed.

This CSNF handling study evaluates the handling of CSNF in air and packaging activities. It evaluates a facility design, further identifies the fuel performance issues, develops the consequences, and presents the operational considerations associated with the routine handling of CSNF in air. Emphasis is on the process of oxidation of
uranium dioxide fuel and additional oxidation-driven failure of fuel assembly cladding. Key
issues are identified, and plans to address these issues are proposed.

Per the requirements of the Task Order 17: Spent Nuclear Fuel Transportation Cask Design
Study, statement of work (SOW), EnergySolutions and its team partners: NAC International,
Talisman International, Booz Allen Hamilton and Exelon Nuclear Partners, hereafter referred to
as “the Team”, is providing a final report for U.S. Department of Energy (DOE) review, which
documents the cask concepts developed under this study and the results of supporting analysis
work.
