The progress so far: An update on the Reactor Pilot Program
It has been about three months since the Department of Energy named 10 companies for its new Reactor Pilot Program, which maps out how the DOE would meet the goal announced by executive order in May of having three reactors achieve criticality by July 4, 2026.

Two suggestions are put forward for avoiding numerical difficulties encountered in the treatment of optically thick media by analytical methods such as Lie series. One is the usual procedure of subdividing a single zone into several subzones. The use of Lie series in connection with this formalism is described. The second method allows a coarser subdivision of a given zone but is restricted to plane geometry.
