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.

A RELAP5-3D Consortium has been formed, comprised of three key entities that have led the development of RELAP5 for decades, namely Idaho National Laboratory, Naval Nuclear Laboratories, and Information Systems Laboratories. By combining the resources of the three leading laboratories, many improvements can be made in the code, the teams, the collaboration, and the overall product. The consortium eliminates competition for new graduating scientist and engineers, combines and leverages the skills, experience, and talents of the three separate teams, creates new synergies, and develops new opportunities. Ultimately, this will extend the productive lifetime of RELAP5-3D to serve the nuclear industry.
