This paper explains the main criteria which are applied as well as measures taken to preserve cladding integrity for the foreseen duration of storage. It discusses in detail the double...
Critical Stresses in Nuclear Waste Container Under Normal Handling Conditions
Critical stresses in the pintle, flat tophead, canister shell, the bottom plate and in the weldment of a high level nuclear waste canister are evaluated under a variety of static and dynamic...
Laboratory Study of Water Infiltration into a Block of Welded Tuff
Scour at a Bridge Over the Weldon River, Iowa
Contraction scour at the State Highway 2 bridge over the Weldon River in south-central Iowa was caused by a flood of record proportions on September 14 and 15, 1992. The peak discharge...
Cavitation Repair by Welding Without Gouging
Homopolar Pulse Butt Welding of API 5L Line Pipe
Homopolar pulse welding (HPW) is a welding process that is being investigated as a means to rapidly join API line pipe, having particularly great potential for application in deepwater...
Critical Stresses in Pintle, Weldment and Top Head of Nuclear Waste Container
On-Orbit Chipless Cutting and Tube Welding in Space Station Freedom
Micro-gravity and strict environmental constraints of the laboratory, Habitation and other manned structures which comprise Space Station Freedom demand investigation into innovative processes...
Fatigue Strength of Welded Joints Under Broadband Loadings
Twelve welded high strength steel cruciform specimens were tested under stochastic loadings to determine the influence on fatigue life of the bandwidth of the loading process. Constant...
