Decommissioned Reactors ( gross ):

The nuclear power plant Hallam (English Hallam Nuclear Generating Station ) was a nuclear power plant with an experimental sodium-cooled graphite-moderated reactor. The nuclear power plant was near Hallam in the U.S. state of Nebraska.

History

The experimental reactor was cooled and sodium- used graphite as moderator. Was built the reactor from 1 January 1959. Commissioning took four years later, on September 1, 1963 instead. The reactor had a thermal output of 256 megawatts. On September 1, 1964, the reactor was shut down because of problems with the moderator. The operating time of the reactor was 335 days. Reason for the short duration of the reactor was too high neutron exposure to the reactor shell, which to corrosion and loss of stability of the reactor pressure vessel with the result. Thus there was a danger of holes in the reactor vessel.
