Division Spotlight
Nuclear Installations Safety
Devoted specifically to the safety of nuclear installations and the health and safety of the public, this division seeks a better understanding of the role of safety in the design, construction and operation of nuclear installation facilities. The division also promotes engineering and scientific technology advancement associated with the safety of such facilities.

Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.

The inner surface of the RFX vacuum vessel is protected by a first wall made up by 2016 polycrystalline graphite tiles. Due to the dimensions of the largest ports, inspection, maintenance and replacement of the first wall components can be carried out only by a remote handling system. Inspections performed during the first four years of operation showed evidence of some plasma surface interaction not only on the graphite tiles, but also on small portions of the vacuum vessel in the interspace between two tiles. Erosion phenomena were observed in the area which corresponds to the insulated poloidal gaps of the stabilizing shell that surrounds the vacuum vessel. New graphite tiles to be installed in these regions were designed, with a shape which completely closes the interspace in the poloidal direction between the tiles. During the last shut down, in 1995, all the 112 tiles were successfully replaced by means of the remote handling system.
