The Nuclear Waste Policy Act of 1982 (NWPA), as amended, assigned the Department of
Energy (DOE) responsibility for developing and managing a Federal system for the disposal of
spent nuclear fuel (SNF) and high-level radioactive waste (HLW). The Office of Civilian
Radioactive Waste Management (OCRWM) is responsible for accepting, transporting, and
disposing of SNF and HLW at the Yucca Mountain repository (if licensed) in a manner that
protects public health, safety, and the environment; enhances national and energy security; and

This is the Nuclear Fuels Storage and Transportation Project Director's presentation on Near Term Planning for Stroage and Transportation of Used Nuclear Fuel presented to the Institute of Nuclear Materials Management on January 14, 2013 in Arlington Va.

The means to prevent and control criticality must be addressed as part of the Preclosure Safety Analysis (PCSA) required for compliance with 10 CFR Part 63 [DIRS 180319], where the preclosure period covers the time prior to permanent closure activities. This technical report presents the nuclear criticality safety evaluation that documents the achievement of this objective.

Presented at WM'03 Conference, Tucson, AZ, February 23-27, 2003

The Used Fuel Disposition (UFD) Transportation Task commenced in October 2010. As its first task, Pacific Northwest National Laboratory (PNNL) compiled a list of structures, systems, and components (SSCs) of transportation systems and their possible degradation mechanisms during extended storage. The list of SSCs and the associated degradation mechanisms [known as features, events, and processes (FEPs)] were based on the list of used nuclear fuel (UNF) storage system SSCs and degradation mechanisms developed by the UFD Storage Task (Hanson et al. 2011).

The purpose of the Foreign Research Reactor (FRR) Spent Nuclear Fuel (SNF) Shipments Institutional Program was to meet the goals and commitments of the Implementation Strategy Plan for the FRR SNF Shipments. This program provided a systematic approach to planning, implementing, evaluating, and validating preparedness for the first west coast shipment of SNF from Asian countries to the Idaho National Engineering and Environmental Laboratory (INEEL).

The amount of spent fuel stored on-site at commercial nuclear reactors will continue to accumulate—increasing by about 2,000 metric tons per year and likely more than doubling to about 140,000 metric tons—before it can be moved off-site, because storage or disposal facilities may take decades to develop. In examining centralized storage or permanent disposal options, GAO found that new facilities may take from 15 to 40 years before they are ready to begin accepting spent fuel. Once an off-site facility is available, it will take several more decades to ship spent fuel to that facility.

This document provides specifications for selected system components of the Transportation, Aging and Disposal (TAD) canister-based system. A list of system specified components and ancillary components are included in Section
1.2.

The preclosure criticality analysis process described in this technical report provides a systematic approach for determining the need for criticality controls and for evaluating their effectiveness during the preclosure period of the Monitored Geologic Repository at Yucca Mountain, Nevada.
