Simulated corium samples were prepared using a sol-gel process to yield U-Zr-oxide materials representative of a molten core covering the whole range of compositions in the U-Zr series. Discs of U-Zr-oxide were compacted by Spark Plasma Sintering (SP

In order to fulfil the requirements as an actinide waste form, cheralite (CaTh(PO 4 ) 2 ) needs to be stabilised into a dense material. Thermal stability studies indicated that heat treatment causes gradual decomposition of CaTh(PO 4 ) 2 into the cor

The solid/liquid transitions in the quaternary U-Pu-Zr-O system are of great interest for the analysis of core meltdown accidents in Pressurised Water Reactors (PWR) fuelled with uranium-dioxide and MOX. During a severe accident the Zr-based cladding

The uncertainty in neutron cross section values strongly depends on the quality and characteristics of the deposited actinide films which are used as “targets” in the nuclear experiments. Until recently, at the Joint Research Centre in Geel (JRC-

Publikováno v: Journal of Aerosol Science. 70:36-49

An experimental set-up has been developed for the production and characterization of aerosols developed from RDDs (Radioactive Dispersion Devices, a.k.a. dirty bombs). Separate effects of temperature, materials and different atmospheres on the produc
