NRC proposes security regulation changes
In 2025, President Trump issued Executive Order 14300, “‘Ordering the Reform of the Nuclear Regulatory Commission,” which directs the NRC to conduct a sweeping, multifaceted overhaul of its structure, culture, and regulations with the aim of facilitating increased deployment of new nuclear technologies and capacity.

In this paper we present the hydrogen diffusivity and solubility in the carbon fibre composite (CFC) SEP N11 with tri-directional fibres structure that is a possible candidate as armour material for plasma facing components (PFC). The technique used for these measurements is a gas evolution method and the measurements were carried out in the temperature range 900 – 1200 K with a loading hydrogen pressure of 100 kPa. The results obtained showed that the Sieverts' constant Ks is of the same order of magnitude as those previously obtained for several graphites, while the diffusivity is about five to six orders of magnitude higher as compared to graphites. Furthermore, CFC presents an endothermic behaviour in contrast to graphites.
