Leona Woods Leona Woods Leona Harriet Woods (August 9, 1919 – November 10, 1986), later known as Leona Woods Marshall and Leona Woods Marshall Libby, was an American physicist who helped build the first nuclear reactor and the first atomic bomb. At age 23, she was the youngest and only female member of the team which built and experimented with the world's first nuclear reactor (then called a "pile"), Chicago Pile-1, in a project led by her mentor Enrico Fermi. In particular, Woods was instrumental in the construction and then utilization of geiger counters for analysis during experimentation. She was the only
EPR (nuclear reactor) In October 2017 the date was pushed back to the beginning of 2019, and in June 2018 to September 2019 due to testing delays. In November 2018 a further delay of four months was announced: regular electricity generation is due to start in January 2020. First concrete was poured for the demonstration EPR reactor at the Flamanville Nuclear Power Plant on 6 December 2007. As the name implies this will be the third nuclear reactor on the Flamanville site and the second instance of an EPR being built. Electrical output will be 1630 MWe (net). The project was planned to
