DOE issues RFI for a spent fuel consolidated interim storage facility
The Department of Energy’s Office of Nuclear Energy has issued a request for information opportunity for the design and construction of a federal consolidated interim storage facility (CISF) for spent nuclear fuel. The DOE is planning on establishing a federal CISF to manage SNF until a permanent repository is available. In May, the DOE received initial approval, known as “Critical Decision-0,” for such a facility.
The deadline for submissions is September 5.

The paper concerns experimental investigations of metallic material erosion under the plasma heat loads expected in ITER divertor during transient events such as the type I edge-localized modes and the disruptions. Primary attention is focused on the erosion due to melt layer movement and splashing. The targets of tungsten and other metals were repeatedly exposed to hydrogen plasma flow of 0.5 ms duration in the heat load range of 0.2-4.5 MJ/m2 at the TRINITI plasma gun QSPA-T. The ejection of liquid droplets was observed during plasma exposure by special recoded system and onset conditions of droplets ejection were defined. Between some of the plasma pulses the eroded surface was analyzed with profilometry and microscopy. The mass loss and exposed surface profile were measured as a function of heat load and number of pulses. Experimentally measured target thinning due to melt layer removal from the exposed area to periphery was compared with erosion due to mass loss as a result of droplets ejection and evaporation. The obtained surface profile was compared with the result of numerical calculations which based on simultaneous solving of the 2-D heat conductivity equation and hydrodynamics equations of “shallow water” approximation.
