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.
The United States Nuclear Regulatory Commission (NRC) defines depleted uranium as uranium with a percentage of the 235 U isotope that is less than 0.711% by weight (see 10 CFR 40.4). The military specifications designate that the DU used by the U.S. Department of Defense (DoD) contain less than 0.3% 235 U. [ 15 ] In actuality, DoD uses only DU ...
Vogtle Units 3 & 4 were brought online in 2023 and 2024, respectively. In June 2008, the U.S. Nuclear Regulatory Commission (NRC) approved a request to increase the generating capacity of Units 1 and 2 by approximately 4.5% each. Luminant Generation Co. implemented the changes during refueling outages.
B&W has submitted a letter of intent for design approval to the Nuclear Regulatory Commission (NRC). [82] Babcock & Wilcox announced on February 20, 2013 that they had contracted with the Tennessee Valley Authority to apply for permits to build an mPower small modular reactor at TVA's Clinch River site in Oak Ridge, Tennessee .
A Super-10 transmission, by contrast, has no range splitter; it uses alternating "stick and button" shifting (stick shifts 1-3-5-7-9, button shifts 2-4-6-8-10). The 13-, 15-, and 18-speed transmissions have the same basic shift pattern but include a splitter button to enable additional ratios found in each range.
Unit 1 has a winter net dependable generating capacity of 1,167 megawatts. Unit 2 has a capacity of 1,165 megawatts. Unit 2 was the first of three new power reactors to enter service in the 21st century in the United States, followed by Vogtle Electric Generating Plant Units 3 and 4.
The Nuclear Regulatory Commission approved the license for both Units 1 & 2 in August, 2024. [3] Unit 1's license will expire on April 1, 2058 and Unit 2's license will expire on August 21, 2060. [3] An artificial lake, Lake Anna, was constructed on the North Anna River to provide a reservoir of water coolant for use with the nuclear plant.
V. C. Summer Unit 1 is a Westinghouse 3-loop Pressurized Water Reactor. The reactor first began commercial operation on January 1, 1984. The plant cost $1.3 billion to construct (equivalent to $4 billion in 2023)– 24 percent less per kilowatt than the average of 13 nuclear plants constructed over the same time period.
