Disney World should have gone nuclear
There is extra significance to the American Nuclear Society holding its annual meeting in Orlando, Florida, this past week. That’s because in 1967, the state of Florida passed a law allowing Disney World to build a nuclear power plant.

In ITER, austenitic stainless steels are under consideration as a blanket structural material for temperature below 200°C. Transmuted helium will be also produced in austenitic stainless steels by high-energy neutron irradiation, and it will affect microstructural development including grain boundary segregation. In this paper, the effects of helium on grain boundary segregation in austenitic stainless steels are studied using ion-irradiation experiment.
The result showed that the onset of radiation induced segregation (RIS) by proton irradiation occurs somewhere between 0.1 and 0.5 dpa. Helium pre-implantation significantly reduced RIS of the major alloying elements. Mechanisms are discussed. Comparison of this result with neutron irradiated induced segregation showed qualitative agreement in the data trends. However, a large amount of segregation was observed in the proton irradiated 304 austenitic stainless steels specimens.
