U.K.’s NWS gets input from young people on geological disposal
Nuclear Waste Services, the radioactive waste management subsidiary of the United Kingdom’s Nuclear Decommissioning Authority, has reported on its inaugural year of the National Youth Forum on Geological Disposal forum. NWS set up the initiative, in partnership with the environmental consultancy firm ARUP and the not-for-profit organization The Young Foundation, to give young people the chance to share their views on the government’s plans to develop a geological disposal facility (GDF) for the safe, secure, and long-term disposal of radioactive waste.

The thermal performance of multilayer PVD tungsten and molybdenum coatings on graphite was studied for the application of first wall in nuclear fusion devices. The coatings with a thickness of 5 μm and different numbers of W/Mo layer were prepared and a series of plasma thermal loads from 1.3 to 4.1 MWm-2 was applied. Microstructure changes caused by thermal loadings were analyzed. Scratch test was then conducted to quantify the changes in the adhesion. The microstructural analysis and scratch test results showed that the thermal performance of the coatings varied depending on the degree of heat loads and coating structure. A molybdenum interlayer improved the coating adhesion while the plasma heat resistance of the double-layer W/Mo coating was slightly better than the others.
