Pu-239 is a 2006 British drama film written and directed by Hollywood producer Scott Z. Burns in his feature directorial debut, which was based on the book PU-239 and Other Russian Fantasies written by Ken Kalfus.
Fissioning of plutonium-239 provides more than one-third of the total energy produced in a typical commercial nuclear power plant. [6] Reactor fuel would accumulate much more than 0.8% plutonium-239 during its service life if some plutonium-239 were not constantly being "burned off" by fissioning. A small percentage of plutonium-239 can be ...

Had all of the plutonium given to Stevens been the long-lived Pu-239 as used in similar experiments of the time, Stevens's lifetime dose would have been significantly smaller. The short half-life of 87.7 years of Pu-238 means that a large amount of it decayed during its time inside his body, especially when compared to the 24,100 year half-life ...
The plutonium-only core, with its high background neutron rate, had a high probability of predetonation, with reduced yield. [13] Minimizing this probability required a smaller mass of plutonium, which limited the achievable yield to about 10 kt, or using highly pure plutonium-239 with impractically low level of plutonium-240 contamination.

Seaborg's role was to figure out how to extract the tiny bit of plutonium from the mass of uranium. Plutonium-239 was isolated in visible amounts using a transmutation reaction on August 20, 1942, and weighed on September 10, 1942, in Seaborg's Chicago laboratory. He was responsible for the multi-stage chemical process that separated ...
