Advanced reactors: Now comes the hard part
Designing a reactor is complicated but building one may be harder. Even companies that have had lots of practice haven’t always done it well. And all the power reactors in service today were built by companies that had years of experience in other kinds of big steam-electric power plants. In contrast, some of the creative new designs now moving toward commercialization come from start-ups that have never built anything at all. How should they prepare?

The specifications on different low-density structures and high-Z admixtures are compared for target designs used to achieve smoother energy flux from different drivers. The experimentally realized aerogels are studied. Various characterization methods are used taking into account their heterogeneity. The physical processes in such materials under the powerful laser irradiation are discussed, in particular transparency dynamics, plasma homogenization, smoothing capability. The further applications of low-density cellulose triacetate (TAC) in the physical experiments are: possible targets for ns- and for ps-lasers, for EUV sources, EOS targets with low-density layer for pressure increase.
