Making the New Look Old
Between March 1990 and January 1991, Annapolis buried overhead utilities and reconstructed the roadway around the historic State House, built in 1769. The paving stones, colonial-appearing...

Jailhouse Design
According to statistics from national corrections groups, the inmate population in the U.S. has reached 1 million and could double by 1995. With the constant need for more beds, engineers...

Simplified Second-Order Inelastic Analysis for Steel Frame Design
Several current approaches are outlined that account for the spreading of plasticity in a second-order inelastic analysis of frames. The approaches are based on modifications to the simple...

Verification of Approximate Methods of Structural Analysis
Sophisticated computer programs for the determination of the effects of instability on the inelastic stress resultants in steel structures will appear to be 'black boxes'...

Development of the ASME/NUPACK Code
A Committee has been active for 10 years to develop Code rules for the design, construction and in-service requirements of containment systems for nuclear spent fuel and high level radioactive...

Certifying the TN-BRP and TN-REG Transportable Storage Demonstration Casks
The U.S. Department of Energy (DOE) has obtained U.S. Nuclear Regulatory Commission (NRC) certification to transport two transportable storage casks for a demonstration project. Because...

Design Considerations for the Yucca Mountain Project Site Characterization
The Site Characterization Facilities (SCF) to be located in volcanic tuff at Yucca Mountain is a challenge to manage, design, and construct. This challenge is a result of a number of factors....

Application of QA Grading to Yucca Mountain Site Characterization Project Items and Activities
Grading is the act of selecting the quality assurance (QA) measures necessary to develop and maintain confidence in the quality of an item or activity. The list of QA measures from which...

High-Level Waste Disposal Regulations: Time for a Change?
Major developments since EPA's high-level radioactive waste disposal regulations were promulgated challenge the validity of some of the assumptions underlying these regulations....

The Development Process for Unique Underground Equipment for Waste Handling
The Department of Energy (DOE) is currently planning to site, construct, and operate a geologic repository at Yucca Mountain, Nevada, for the disposal of high-level nuclear waste (HLW)....

How Can the St. Lucie Unit 2 Licensing Experience Benefit the Licensing of a Nuclear Spent Fuel Repository
The Nuclear Regulatory Commission (NRC) granted a full power operating license for St. Lucie Unit 2 on June 10, 1983, just six years after construction began. The industry average for...

Effect of HNO3-Cerium(IV) Decontamination on Stainless Steel Canister Materials
Stainless steel canisters will be filled with vitrified radioactive waste at the West Valley Demonstration Project (WVDP), West Valley, NY. After they are filled, the sealed canisters...

Regulatory Requirements and Long-Term Repository Host Rock Performance
The regulatory requirements governing the disposal of high-level radioactive wastes in mined geologic repositories acknowledge the long-lived nature of the wastes and require the consideration...

Modelling Studies for the Assessment of the Advanced Cold Process Canister
The Advanced Cold Process Canister (ACPC) is a new concept for the encapsulation of spent nuclear fuel for geological disposal. It consists of steel canister encased in a copper overpack....

Mechanical Excavator Performance in Yucca Mountain Tuffs
A research effort of four phases is in progress at the Colorado School of Mines. The overall program will evaluate the cutability of welded tuff and other lithologies likely to be excavated...

The Adoption of Mechanized Excavation Techniques for the Superconducting Super Collider
The Superconducting Super Collider (SSC) is the latest and largest in a line of high-energy physics accelerator projects. The five increasingly energetic accelerators which make up the...

Principles of the NATM and Other Uses of the Geologic Monitoring Techniques
The NATM (New Austrian Tunneling Method) differs in several respects from other construction methods. Also referred to as the 'sequential support method' or the...

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...

Scenario Evolution: Interaction Between Event Tree Construction and Numerical Analyses
Construction of well-posed scenarios for the range of conditions possible at any proposed repository site is a critical first step to assessing total system performance. Event tree construction...

The Technical Challenge of Mechanized Excavation for Nuclear Waste Repositories
The requirements of mechanized tunnelling and shafting techniques within this newly developing field, namely the excavation of Nuclear Waste Repositories, will challenge the designers...
