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.

Heat transfer rates to spray droplets under conditions corresponding to those of a loss-of-coolant accident in a light water nuclear reactor have been recalculated in light of the discovery of missing mass exchange terms in the equations of motion used in a previously published computation. While the inclusion of these missing terms into the model equations proves to make only a small difference in the rate of temperature increase of the droplet, the fall distance of the droplets, important in spray heat transfer efficiency, is significantly altered. Furthermore, it is shown that the predicted fall distance, e.g., at 95% temperature interval increase, is very sensitive to the drag law employed in the calculation.
