Preliminary Calculations of Release Rates from Spent Fuel in a Tuff Repository
Time-dependent release rates of Tc-99, I-129, Cs-135, and Np-237 have been calculated for wet-drip and moist-continuous release modes from the engineered barrier system of a potential...

The Standard Contract's Delivery Commitment Schedule Process
The Standard Contract for the Disposal of Spent Nuclear Fuel and/or High-Level Radioactive Waste specifies various activities necessary for the eventual acceptance of spent nuclear fuel...

A Comparison of High-Level Waste Form Characteristics
The U.S. Department of Energy is responsible for the eventual disposal in a repository of spent fuels, high-level waste (HLW) and other radioactive wastes that may require long-term isolation....

Effects of Spent Fuel Aging on Repository Disposal Requirements
A study has been carried out to analyze the effects of extended spent fuel aging on spent fuel disposal requirements. The analysis considers additional spent fuel aging up to a maximum...

Conclusions from Project-90 With Regard to a Regulatory Framework
A five year performance assessment program, Project-90 [1], has been concluded by the Swedish Nuclear Power Inspectorate, SKI. The project was defined to develop independent assessment...

CALIBRE and CRYSTAL: Near-field and Geosphere Models for Project-90
A new near-field model (CALIBRE) and a fractured geosphere model (CRYSTAL) have been developed in support of the Swedish Nuclear Power Inspectorate's Project-90 safety assessment...

Preliminary Performance Assessment of a Nevada Test Site Waste Disposal Facility
The performance of the Nevada Test Site Greater Confinement Disposal (GCD) site was assessed against the Environmental Protection Agency's (EPA) requirements for disposal...

Scoping Experimental Analysis of Factors Affecting Cask Contamination Weeping
One issue of particular concern to both the US Nuclear Regulatory Commission (NRC) and the US Department of Energy (DOE) involves the control of in-transit 'weeping'...

Case Studies in Cooperation with External Groups
Public confidence in the safety of the high-level radioactive waste program can be improved by meaningful participation in the decisionmaking process. Public involvement and the resultant...

OCRWM'S Evolving Strategic Planning Process and the 1990 Plan
In 1990, the Secretary of Energy (Secretary Watkins) ordered that all 23 of the Department's major organizations adopt systems of strategic planning. This paper explains the...

Historical Overview of Domestic Spent Fuel Shipments?Update
The information in this paper summarizes historic data on spent fuel shipments in the United States. The data are updated periodically to keep abreast of changes. Information on shipments...

Transportation Capabilities of the Existing Cask Fleet
This paper describes a number of scenarios estimating the amount of spent nuclear fuel that could be transported to a Monitored Retrievable Storage (MRS) Facility by various combinations...

A Preliminary Evaluation of the Ability of From-Reactor Casks to Geometrically Accommodate Commercial LWR Spent Nuclear Fuel
The Department of Energy has sponsored a number of cask design efforts to define several transportation casks to accommodate the various assemblies expected to be accepted by the Federal...

The MD Design?A Cool Concept for Geologic Disposal of Radioactive Waste
The scheduled disposal capacity for spent nuclear fuel and other high-level radioactive wastes (HLW) is inadequate and the estimated supply of recoverable uranium for continued nuclear...

Dry Spent Fuel Storage in the 1990's
In the United States, for the decade of the 1990's, at-reactor-site dry spent fuel storage has become the predominant option outside of reactor spent fuel pools. This development...

A Proposed Regulatory Guide Basis for Spent Fuel Decay Heat
A proposed revision to Regulatory Guide 3.54, 'Spent Fuel Heat Generation in an Independent Spent Fuel Storage Installation' has been developed for the U.S. Nuclear...

Evaluation of Storage/Transportation Options to Support Criteria Development for the Phase I MRS
The Department of Energy's (DOE) Office of Civilian Waste Management (OCRWM) plans to develop an interim storage facility to enable acceptance of spent fuel in 1998. It is...

A High-Level Waste Repository Performance Assessment Methodology
This project was sponsored by the Electric Power Research Institute to examine methods that coordinate information from various disciplines to present an integrated perspective on the...

Structural Optimization to Limit Natural Periods
It is necessary to limit the natural periods of some structures to control their response to dynamic loads. Floor systems with natural periods greater than approximately 0.15 seconds may...

Energy in the 90's
This proceedings consists of papers presented at the specialty conference Energy in the Nineties which was sponsored by the Energy Division of the American Society of Civil Engineers and...
