Development on inelastic analysis acceptance criteria for radioactive material transportation packages

Description: The response of radioactive material transportation packages to mechanical accident loadings can be more accurately characterized by non-linear dynamic analysis than by the ``Equivalent dynamic`` static elastic analysis typically used in the design of these packages. This more accurate characterization of the response can lead to improved package safety and design efficiency. For non-linear dynamic analysis to become the preferred method of package design analysis, an acceptance criterion must … more

Modelling considerations for large deformation impact problems

Description: Transport casks used to move spent nuclear fuel between storage locations must be designed for accidental drops which may occur during cask handling. The potential for damage is especially significant for side drops, where deformations of the cask inner cavity are likely to be the most severe. There are various analytical methods available to evaluate the deceleration and deformation of a cask for a postulated side drop, but little test data to support them. In this study, three techniques to d… more

Analytical determination of package response to severe impact

Description: One important part of radioactive material transport risk assessments is amount of release from packages in accidents more severe than design basis accident (US NRC 10CFR71 1995). In order to remove some of the conservatism from current risk assessments, an effort is ongoing to qualify the finite element method for predicting cask performance by comparing analytical results to test measurements of the Structural Evaluation Test Unit (SETU) cask. Comparisons of deformed shapes, strains, and acce… more

Stress-temperature-lifetime response of nicalon fiber-reinforced SiC composites in air

Description: Time-to-failure tests were conducted in four-point flexure and in air as a function of stress levels and temperatures to study the lifetime response of various Nicalon fiber-reinforced SiC (designated as Nic/SiC) composites with a graphitic interfacial coating. The results indicated that all of the Nic/SiC composites exhibit a similar stress-dependent failure at applied stress greater than a threshold value. In this case, the lifetimes of the composites increased with decrease in both stress le… more

Evaluation of seismic capacity of glovebox windows using deformation tests

Description: With the increasing emphasis on worker safety, gloveboxes are being relied upon in Safety Analyses to be a confinement boundary. Many of the accident scenarios result in a requirement that these gloveboxes be seismically qualified. Since there is currently no validated experience data category for gloveboxes, the qualification has generally been done by analysis. The weak link in assuring confinement integrity by analysis is in characterizing the glass and glass-to-glovebox seal in the analytic… more
