Criticality Safety Evaluation of Materials Concerning Pyroprocessing

On the Safety of Mixed-Criticality Scheduling

A common assumption for scheduling mixedcriticality systems is the degradation of less critical tasks when the system is in the emergency mode; which is entered when critical tasks overrun their expected WCET. In the meanwhile, common safety standards enforce strict safety requirements on all criticality levels. However, the impact of degrading less critical tasks on the overall system safety i...

Introduction to Criticality Accident Evaluation

So far 22 criticality accidents have been reported (McLaughlin et al., 2000) including JCO accident in Japan. All cases took place with fuel solution or slurry except one case of metal fuel. It was not clear that what was actually happening during those criticality accidents except the JCO accident, for which a fission power profile was reproduced from a gammaray monitoring data (Tonoike et al....

Criticality in non-linear transport properties of heterogeneous materials

2014 In heterogeneous materials consisting of individual simple non-linear elements whose transport characteristics are piecewise linear separated by random « thresholds », one may encounter transition regimes where a power law relates fluxes to potentials. There is a well-defined threshold for the onset of this transition regime. We suggest that this threshold is a critical point closely relat...
