U.S. energy secretary Jennifer Granholm and International Atomic Energy Agency director general Rafael Mariano Grossi met in Vienna yesterday during the agency’s 65th General Conference to launch preparations for the next IAEA International Ministerial Conference on Nuclear Power in the 21st Century, slated for October 26–28, 2022, in Washington, D.C.
The American Nuclear Society wrote to Congress, urging the need for a domestic supply of high-assay, low-enriched uranium.
September 15, 2021, 3:42PMUpdated September 15, 2021, 3:43PMPress Releases The United States Congress needs to take swift action to build a domestic supply of fuel for advanced reactors and to avoid future dependence on Russia for advanced nuclear fuel, the American Nuclear Society wrote in a Sept. 14 letter to the U.S. Senate Energy and Natural Resources Committee.

Portland, Ore.–based NuScale Power has announced the signing of a memorandum of understanding with the Grant County Public Utility District (Grant PUD) to evaluate the deployment of NuScale’s advanced nuclear technology in central Washington state.
May 21, 2021, 2:41PMNuclear NewsCharles Forsberg and Eric Ingersoll TerraPower and GE Hitachi Nuclear Energy jointly developed the sodium-cooled Natrium reactor with the turbine hall, nitrate heat storage tanks, and cooling towers separated from the reactor at the back of the site.
The viability of nuclear power ultimately depends on economics. Safety is a requirement, but it does not determine whether a reactor will be deployed. The most economical reactor maximizes revenue while minimizing costs. The lowest-cost reactor is not necessarily the most economical reactor. Different markets impose different requirements on reactors. If the capital cost of Reactor A is 50 percent more than Reactor B but has characteristics that double the revenue, the most economical reactor is Reactor A.
The most important factor is an efficient supply chain, including on-site construction practices. This is the basis for the low capital cost of light water reactors from China and South Korea. The design of the reactor can significantly affect capital cost through its impact on the supply chain. The question is, how can advanced reactors boost revenue and reduce costs?
