Les accidents graves de reacteurs ou accidents de fusion du coeur sont caracterises par l’importance des rejets radioactifs qu’ils peuvent generer. En consequence, un ensemble de mesures de prevention comme de limitation des consequences ont ete

Le 28 mars 1979, a la centrale nucleaire de Three Mile Island en Pennsylvanie (Etats-Unis), une serie de defaillances materielles et humaines provoquaient la fusion partielle du coeur du reacteur nucleaire : les concepteurs et les exploitants d’ins

Jointed goatgrass is a problem weed in winter wheat production areas of the Great Plains. Winter wheat seeding rates are easily adjusted by the growers and influence competition by some weeds. Field experiments were initiated in Kansas, Nebraska, and

The two-dimensional (2-D) radiation-magnetohydrodynamic (R-MHD) code FOREV-2 was developed for modeling of disruptive hot plasma-wall interaction, for calculation of erosion by evaporation of the ITER-FEAT vertical divertor target, and for calculatio

For calculation of target erosion, the plasma shield formation and its shielding efficiency in front of the target have to be known. For this purpose the 2-D multifluid radiation magnetohydrodynamics (R-MHD) code FOREV-2 was developed. FOREV-2 valida

During off-normal events besides evaporation macroscopic erosion might occur. In carbon-based materials (CBMs) macroscopic erosion means brittle destruction and dust formation and in metals melt layer motion and droplet splashing. Dust, melt flow, dr

Dynamics of carbon plasma shields and graphite target erosion experimentally studied at the recently upgraded plasma gun facility MK-200 UG at TRINITI Troitsk are compared with numerical results from FOREV-2 which allows a 2-D modeling of hot plasma

Disruptions and giant ELMs in ITER will deposit a large power load on the divertor plates. The amount of ablated material is important for plate lifetime and in determining the amount of plate material that escapes to the core region. The ablated vap
