"More powerful than uranium"; used by men from the Moon. Metal X (Rovolon) E. E. Smith's SkyLark series: An element discovered that facilitates conversion of the energy in metals (copper or uranium) and uses it as a propulsive or attractive force. The Norlaminians had already discovered this metal and named it Rovolon.
An electric current is applied, causing the uranium metal (or sometimes oxide, depending on the spent fuel) to plate out on a solid metal cathode while the other actinides (and the rare earths) can be absorbed into a liquid cadmium cathode. Many of the fission products (such as caesium, zirconium and strontium) remain in the salt.
According to the patent application [5] the reactor design has some notable characteristics, that sets it apart from other reactor designs. It uses uranium hydride (UH 3) "low-enriched" to 5% uranium-235—the remainder is uranium-238—as the nuclear fuel, rather than the usual metallic uranium or uranium dioxide that composes the fuel rods of contemporary light-water reactors.
Satisfactory was made available for early access on 19 March 2019. By January 2024, the game had sold 5.5 million copies. [2] The full version of the game was released on 10 September 2024. [3] With the full release, Coffee Stain has also announced plans for a console version. [4]
The radium ore Revigator was a pseudoscientific medical device consisting of a ceramic water crock lined with radioactive materials. It was patented in 1912 by R. W. Thomas. [1] Thomas was working at the time as a stock salesman in Arizona [2] but, by 1923, had moved to southern California to begin manufacture of his patent. In 1924, following ...
The uranium to zirconium ratio in different parts of the solid differs a lot, in the brown lava a uranium-rich phase with a U:Zr ratio of 19:3 to about 19:5 is found. The uranium-poor phase in the brown lava has a U:Zr ratio of about 1:10. [37] It is possible from the examination of the Zr/U phases to determine the thermal history of the mixture.
Uranium fuel was placed in aluminium canisters and pushed into the channels in the front, pushing previous fuel canisters through the channel and out the back of the reactor where they fell into a pool of water. The system was designed to work at low temperatures and power levels and was air-cooled with the help of large fans. [2] [3]
If in situ resource utilization is desired to fuel nuclear power plants on the moon, converting fertile material to fissile material could be a way to make the resources last longer and to reduce the need for uranium enrichment which requires the chemically aggressive volatile fluorine to prepare uranium hexafluoride as used in the current ...
