Solids with a large density of states at the Fermi level become unstable at low temperatures and tend to form ground states where the condensation energy comes from opening a gap at the Fermi surface.

For examples of things measuring between one and ten femtometres, see. Femtometre Unit of Symbol fm Conversions 1 fm in. 000000000♠1 ×10 −00♠6.1877 ×00000♠1.8897 ×10 −5 / units 3.9370 ×10 −14 The femtometre (American spelling femtometer, symbol fm derived from the Danish and Norwegian word femten, 'fifteen'+: μέτρον, metrοn, 'unit of measurement') is an unit of equal to 10 −15, which means a quadrillionth of one. This distance can also be called a fermi and was so named in honour of physicist, as it is a typical length-scale of. Definition and equivalents [ ] 1000 = 1 femtometre = 1 fermi = 0.001 = 000000000♠1 ×10 −00♠1 000 000 femtometres = 10 = 1.

For example, the charge of a is approximately 0.84–0.87 femtometres while the radius of a is approximately 8.45 femtometres. 1 = 100 fm 2 History [ ] The femtometre was adopted by the 11th, and added to SI in 1. The fermi is named after the (1901–1954), one of the founders of nuclear physics. The term was coined by in a 1956 paper published in entitled 'Electron Scattering and Nuclear Structure'. The term is widely used by nuclear and physicists. [ ] When Hofstadter was awarded the 1961 Nobel Prize in Physics, it subsequently appears in the text of his 1961 Nobel Lecture, 'The electron-scattering method and its application to the structure of nuclei and nucleons' (December 11, 1961).

Despite the name, the Connect has no engineering commonality with the full-size Transit. 2003 saw a new instrument cluster with a digital odometer.

On October 5, 1966 Fermi 1. Two of the 92 fuel assemblies were partially damaged. According to the, there was no abnormal radioactivity released to the environment.

Fermi 1 was a design. It was capable of producing 200 megawatts thermal (MWt) power or 69 MW electrical power with 26% enriched metallic uranium fuel. The section of the reactor (core) was a 30 inch in diameter cylinder by 30 inches high and contained 92 fuel assemblies. The core was surrounded by 548 additional assemblies containing depleted uranium.

These assemblies were about 2.5 inches square by about 8 feet tall. Only the core section contained the enriched uranium while was placed above and below within the assemblies. The core also contained 2 control rods and 8 safety rods. The plant was designed for 430 MWt and 125 MWe using a newer uranium oxide fuel, but the plant was closed before the fuel was ever ordered. The shield plug was a rotating part of the inner reactor vessel and sat over the fuel. It could be rotated in order to facilitate fuel movements.

The shield plug also provided radioactive shielding. During fuel loading, new assemblies were lowered down a tube into an adjacent Transfer Rotor which was integral with the reactor vessel. Then an Offset Handling Mechanism lifted the assembly from the Transfer Rotor and placed it into the vessel. Once all of the assemblies were loaded, a Hold Down Mechanism sat atop them so as to prevent them from moving upwards during operation.

The Hold Down Mechanism also contained temperature measuring devices (resistance temperature detectors) to monitor sodium outlet temperatures from the assemblies. The (primary) sodium which flowed through the core exchanged heat with a secondary sodium system which then exited the containment. The secondary sodium then passed through the tube side of 3 parallel steam generators and transferred heat to water on the shell side. The “once through” design produced superheated steam which turned the main turbine-generator. A 168 oil-fired boiler was added in 1966 to utilize the turbine-generator during periods when the reactor was not producing power.
