Between the time of the discovery of nuclear fission in early 1939 and the end of 1946, approximately 90 “nuclear piles” were constructed in six countries. These devices ranged from simple graphite columns containing neutron sources but no uranium to structures as complex as the water-cooled 250-MW plutonium production reactors built at Hanford, Washington. This paper reviews and compares the properties of these piles. 


Uranium from German Nuclear Power Projects of the 1940s— A Nuclear Forensic Investigation
To determine the geographical origin of the uranium, the rare-earth-element content and the 87Sr/86Sr ratio were measured and provide evidence that the uranium was mined in the Czech Republic.

A Neutronics Study of the 1945 Haigerloch B-VIII Nuclear Reactor
We present a neutronics study of the German B-VIII nuclear reactor, which was built in Haigerloch, Germany, between February and April 1945. We used the Monte Carlo code MCNP5 to estimate its
The Search for Transuranium Elements and the Discovery of Nuclear Fission
Abstract. The synthesis of new, artificial elements beyond uranium was at the cutting-edge of physical research in the 1930s, and nearly half a dozen transuranium elements were reported between 1934

Graveyard shift, Hanford, 28 September 1944: Henry W. Newson
An account is given of the surprise effects of 135Xe fission product poisoning in the initial operation of the first Hanford plutonium production reactor.
Experimental Production of a Divergent Chain Reaction
Except for minor editorial revisions this paper is the reproduction of a report written for the Metallurgical Laboratory of the University of Chicago almost ten years ago, after the experimental
Tracking the journey of a uranium cube
A mysterious object led two physicists to investigate the German quest and failure to build a working nuclear reactor during World War II.
Physics at Columbia University: The genesis of the nuclear energy project
It seems fitting to remember, on this 200th anniversary of Columbia University, the key role that the University played in the early experimentation and the organization of the early work that led to
