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.

In a reactor of sufficient size and operating at sufficiently high power density, an oscillation in the spatial distribution of power may arise because of interplay between the effect of Xe135 on flux distribution and the fact that its appearance after fission is delayed by the decay time of I135. By use of a very simple reactor model the conditions required to establish such an instability are studied; amplitude and frequency characteristics of the oscillation are also investigated.
