DOE, INL, Kairos talk nuclear energy at Senate committee hearing
It has been 10 months since President Trump signed several executive orders that have reshaped the nuclear energy industry and set lofty goals for initiatives like the development and deployment of new nuclear technology.
One such initiative, the DOE’s Nuclear Reactor Pilot Program, calls for at least 3 of the 11 reactors in the program to achieve criticality by July 4, 2026. Some have questioned whether this target is feasible.

The retention of tritium (T) by carbon based deposits on tokamak surfaces is of increasing concern to the fusion community as the scale of tritium retention by this mechanism could be a limiting factor for the operation of fusion reactors, such as ITER. Hence there is a need to investigate ways of mitigating T retention and also for detritiating surfaces by either desorption of T or removal of tritiated deposits. The results of the removal of codeposits from CFC tiles by pulsed laser ablation are reported here. The results show that it is possible to completely remove a 300m thick hydrogen isotope rich carbon film at a rate of 12x10-3m2/hr by this method and that with optimisation of the laser parameters there is scope to improve the treatment rates to provide a useful tool for managing T inventory in tokamaks.
