GA-4/GA-9 Honeycomb Impact Limiter Tests and Analytical Model
General Atomics (GA) has a test program underway to obtain data on the behavior of a honeycomb impact limiter. The program includes testing of small samples to obtain basic information,...

Perils of Project Development on Public Land Open to Mining
Conducting a government project on public land open to the general mining laws can result in added costs, legal entanglements, schedule uncertainties, and the potential for unanticipated...

Seeking Common Ground: Western Governors and the WIPP Transport Campaign
Nine Western States have engaged the U.S. Department of Energy (USDOE) to prepare for shipments of nuclear weapons waste. These are shipments of transuranic (TRU) wastes from nuclear weapons...

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...

An Integrated Systems Approach to Institutional/Technical Program Milestone Planning and Implementation in the Civilian Radioactive Waste Management Program
A broad spectrum of public and private sector institutions in the United States has concerns about the high-level radioactive waste management program. An integrated systems approach is...

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...

Damage-Tolerant Design of Deterministic and Nondeterministic Structural Systems
Many structures are exposed to very hazardous environments and they are likely to be damaged during their lifetime. Damage occurrence may cause a dramatic reduction in the safety of structural...

Optimization of RC Frames with Reliability Concepts
Analysis and design optimization are considered simultaneously for reinforced concrete frames. Global displacements were considered as design variables. The nonlinear behavior of the elements...

Downstream Danger from Sudden Discharges of Water
The sudden, unexpected release of water by hydropower facilities poses a threat to fishermen and boaters immediately downstream. The characteristics of the danger can be identified, however,...

A 1990's Strategy for Combined Sewer Improvements
On June 22, 1990, the Regional Water Quality Control Board issued the City of Sacramento a Cease and Desist Order. The Order required the City to examine the condition of, and flooding...

Nonlinearities and Imperfections in Creep Stability
The effects of material and geometric nonlinearities and imperfections on the 'safe-load-limit' and the 'safe-service-period' of structures...

Response Variability and Reliability of Stochastic Systems Using the Weighted Integral Method
After obtaining an exact expression of the stochastic stiffness matrix in terms of random variables called weighted integrals, the response variability and the safety index of stochastic...

System Identification Techniques for Inelastic Structures
A classical optimization algorithm is used to identify the parameters of a smooth hysteretic restoring force model, which can be used to describe the inelastic behavior of structures under...

Safe-Load-Limit of Plates in Cylindrical Bending
The derivation of a closed-form expression for the viscoelastic critical load of long thin plates undergoing cylindrical bending and made of a linear time-dependent 'solid'-type...

Pipeline Crossings
This proceedings of the Pipeline Crossings Conference, held on March 25-27, 1991 in Denver, Colorado, presents information on aspects of various pipeline crossings. It covers such broad...

Safeguarding History
Even monolithic marble monuments, such as the Thomas Jefferson Memorial, fall prey to materials deterioration. Now, sensitive instrumentation systems can document and analyze even the...

Risk Management in the Transportation of Dangerous Goods?The Influence of Public Perception A Discussion
In 1988, a fire at Saint-Basile-le-Grand, Quebec involving a PCB (polychlorinated biphenyls) warehouse sparked continuing controversy which included a two-week evacuation of residents....

Developing High-Risk Scenarios and Countermeasure Ideas for Mitigation of Hazardous Materials Incidents
Kansas State University (KSU) conducted a comprehensive study of the development of a set of prioritized, extreme-risk scenarios, the development of a set of feasible, practical and implementable...

Risk Perception and Policy Preferences of Fire Chiefs: A Survey of Hazardous Materials Issues
This paper presents the results of a survey of Connecticut fire chiefs and discusses how their perceptions of risk affect their attitudes towards risk preparedness and risk management...

Flows of Hazardous Materials Through States by Rail
This paper presents information on the tonnages of hazardous materials passing through each of the contiguous 48 states (and the District of Columbia) by rail. The quantities are estimated...
