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?

We built a precision radiography system that measures shells for all current ablator materials to an accuracy of 1:104 in optical depth fluctuation and a spatial resolution of 120 m. The data obtained by the precision radiography system for undoped shells was compared with the data taken using the well-known surface measurement technique Spheremapper. Since both techniques yielded the same power spectrum for the same shell, the results of the precision radiography system were verified. When this technique is compared to the Be:Cu NIF shell, there is no significant internal layer fluctuation. To account for the growing measurement demand, a new x-ray system to accommodate measurements in 1 working day was designed.
