The Department of Energy’s National Nuclear Security Administration has awarded BWX Technologies a contract valued at $1.5 billion to build a Domestic Uranium Enrichment Centrifuge Experiment (DUECE) pilot plant in Tennessee in support of the administration’s efforts to build out a domestic supply of unobligated enriched uranium for defense-related nuclear fuel.

This technical note offers comments and suggestions regarding four issues involved with the Frisch-Peierls memorandum of 1940: (1) Propagation of transcription errors in subsequent publishings of the memorandum; (2) Data bearing on F&P’s adoption of 10 b as the fission cross section of 235U; (3) The origin of their assertion that the critical radius is about 0.8 times the mean free path for fission if scattering is disregarded; and (4) The origin of a multiplicative factor of 0.2 in their yield formula and the consistency of their calculations.
