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.

Air detritiation dryers at fusion facilities require high detritiation factors to minimize environmental releases. To increase the detritiation factor in air dryers, we have investigated a technique of eluting the residual adsorbed tritiated water on a molecular sieve bed that uses H2O steam washing during regeneration. The method relies on additional detritiation of the air stream occurring through isotopic exchange between the tritiated water vapor passing through a dryer bed with previously adsorbed non-tritiated water. Isotopic exchange is studied in both an operating industrial-scale air dryer, where the bed has been pretreated to remove tritium, and in a small laboratory bed. A mathematical model is presented to quantify the isotopic exchange process.
