A core shroud is a stainless steel cylinder surrounding a nuclear reactor core whose main function is to direct the cooling water flow. [1] The nuclear reactor core is where the nuclear reactions take place. Because the reactions are exothermic, cool water is needed to prevent the reactor core from melting down. The core shroud helps by ...
We Almost Lost Detroit, a 1975 Reader's Digest book by John G. Fuller, [1] presents a history of Fermi 1, America's first commercial breeder reactor, with emphasis on the 1966 partial nuclear meltdown. [2] [3] It took four years for the reactor to be repaired, and then performance was poor.
In 1999, University of Chicago physics majors Justin Kasper and Fred Niell, as part of a scavenger hunt that had as one of its items "a breeder reactor built in a shed," successfully built a similar nuclear reactor that produced trace amounts of plutonium. [19] In the CSI: NY episode "Page Turner", the character Lawrence Wagner is based on Hahn ...
Whilst most power reactors do have a pressure vessel, they are generally classified by the type of coolant rather than by the configuration of the vessel used to contain the coolant. The classifications are: Light-water reactor - Includes the pressurized water reactor and the boiling water reactor. Most nuclear power reactors are of this type.
In September 2008, Detroit Edison filed an application with the Nuclear Regulatory Commission (NRC) for a Combined Construction and Operating License (COL) for a third reactor. [7] The new unit is supposed to be built on the same site, slightly to the southwest of Fermi 2.
The reactor vessel itself arrived in May 1958, after a month-long barge and rail journey. [34] By early 1958, cost estimates had risen to $70 million (equivalent to $759,000,000 in 2023), double the initial estimate. The final part of the reactor assembly arrived in May 1959, leaving only the steam plant to be completed. [35]
The reactor is intended to be launched cold, preventing the formation of highly radioactive fission products. Once the reactor reaches its destination, the neutron absorbing boron rod is removed to allow the nuclear chain reaction to start. [7] Once the reaction is initiated, decay of a series of fission products cannot be stopped completely ...
A breeder reactor is a nuclear reactor that generates more fissile material than it consumes. [1] These reactors can be fueled with more-commonly available isotopes of uranium and thorium, such as uranium-238 and thorium-232, as opposed to the rare uranium-235 which is used in conventional reactors.
