A sample of thorium. Thorium-based nuclear power generation is fueled primarily by the nuclear fission of the isotope uranium-233 produced from the fertile element thorium.A thorium fuel cycle can offer several potential advantages over a uranium fuel cycle [Note 1] —including the much greater abundance of thorium found on Earth, superior physical and nuclear fuel properties, and reduced ...
Thorium is a future potential source of low-carbon energy. [1] Thorium has been demonstrated to perform as a nuclear fuel in several reactor designs. [2] [3] It is present with a higher abundance than uranium in the crust of the earth. Thorium resources have not been estimated and assessed with a higher level of confidence, as in the case of ...
A two fluid reactor that has thorium in the fuel salt is sometimes called a "one and a half fluid" reactor, or 1.5 fluid reactor. [26] This is a hybrid, with some of the advantages and disadvantages of both 1 fluid and 2 fluid reactors. Like the 1 fluid reactor, it has thorium in the fuel salt, which complicates the fuel processing.
Oregon electricity production by type. This is a list of electricity-generating power stations in the U.S. state of Oregon, sorted by type and name.In 2022, Oregon had a total summer capacity of 17,243 MW through all of its power plants, and a net generation of 61,317 GWh. [2]
At the very beginning the RB reactor was designed and constructed as an unreflected zero power heavy water - natural uranium critical assembly. First criticality was reached in April 1958. Later, the 2% enriched metal uranium fuel and 80% enriched UO 2 fuel were obtained and used in the reactor core.
Although thorium dioxide performed well at burnups of 170,000 MWd/t and 150,000 MWd/t at Fort St. Vrain Generating Station and AVR respectively, [6] challenges complicate achieving this in light water reactors (LWR), which compose the vast majority of existing power reactors. In a once-through thorium fuel cycle, thorium-based fuels produce far ...
Trojan Nuclear Power Plant was a pressurized water reactor nuclear power plant (Westinghouse design) in the northwest United States, located southeast of Rainier, Oregon, [2] and so far, the only commercial nuclear power plant to be built in Oregon. There was much public opposition to the plant from the design stage.
The Salem Nuclear Power Plant, as photographed from Delaware Bay. Both reactors use Delaware Bay as a source of cooling water. Salem Units 1 and 2 have a water-intake building with a rotating screen to collect debris that is later washed off. Sometimes thick layers of grass clog the intakes and the reactors run at reduced power for weeks as a ...
