Comments on U.S. nuclear export controls on China
As trade negotiations are in the works between the United States and China, Washington, D.C., has the advantage in semiconductors but nuclear power is a different story, according to a June 9 article in the Hong Kong–based South China Morning Post.

The distribution of enrichment which makes a natural uranium lattice with k∞ < 1 critical with the smallest amount of added U235 is calculated on the basis of a simple model. The results are generalized to the minimization of total enrichment cost when this cost is a nonlinear function of the added fissionable material.
