W-Cr-Y smart alloys are potential material candidates for plasma facing components due to their protective behaviour during the loss-of-coolant accident (LOCA), while maintaining beneficial properties of W normal operation fusion power plant. During exposure, lighter alloying elements preferentially sputtered at surface, but in case a LOCA, quenches and sputtering stops diffusion surface become...

BACKGROUND Differentiating idiopathic late-onset cerebellar ataxia (ILOCA) from ataxia due to the cerebellar subtype of multiple-system atrophy (MSA-C) can be difficult in the early stages of the disease METHODS The authors analyzed the levels of various CSF biomarkers in 27 patients with MSA-C and 18 patients with ILOCA and obtained cut-off points for each potential biomarker to differentiat...

Outcomes of an activity on development and verification models for Fission Gas Release in Light-Water Reactor fuels during Loss-of-Coolant Accidents are described. The GRSW-A model the FALCON code is extended to simulate processes fuel fragmentation concomitant transient Release. FRELAX redesigned with a view simulation bulk flow diffusion gases rod free volume. Finally, close coupling updated ...

Cr-coated Zr-alloys are a near-term cladding concept to improve reactor safety during accident scenarios. Burst and steam oxidation behavior of bare Zirlo claddings were examined under simulated loss-of-coolant conditions. The 4.4 µm coating had no substantial effect on ballooning or opening geometry but did increase burst temperatures at higher pressures. reduced the compared specimens, in reg...
