The Frisch-Peierls memorandum: A seminal document of nuclear history
The Manhattan Project is usually considered to have been initiated with Albert Einstein’s letter to President Franklin Roosevelt in October 1939. However, a lesser-known document that was just as impactful on wartime nuclear history was the so-called Frisch-Peierls memorandum. Prepared by two refugee physicists at the University of Birmingham in Britain in early 1940, this manuscript was the first technical description of nuclear weapons and their military, strategic, and ethical implications to reach high-level government officials on either side of the Atlantic. The memorandum triggered the initiation of the British wartime nuclear program, which later merged with the Manhattan Engineer District.

Cesium-exchanged Type 4A zeolites can encapsulate high-pressure tritium by physical entrapment in interior pores. We present data on storage capacity related to physical pore volume in the zeolite, and show that storage stability is reasonably good for short periods. Our data also shows that the zeolite releases helium while retaining tritium. Results are analyzed in terms of a diffusion model in the literature. The zeolite showed no structural change after a radiation dose of 108 Gy; it is unclear if radiation affects storage stability.
