UK's First TerraPower Natrium Reactor Could Generate Power by 2034

TerraPower, the US nuclear power company backed by Bill Gates, expects its Natrium sodium-cooled reactor could generate electricity in the UK as early as 2034. If the project progresses smoothly, the UK will become the company's first market for deploying this technology outside the United States. TerraPower CEO Chris Levesque said that given the company's first Natrium reactor project is scheduled for completion in 2031, the Natrium technology is highly likely to become a reality in the UK by 2034. The technology has already met relevant US regulatory requirements, and the first unit is under construction in Wyoming. In recent years, the UK has accelerated the development of small modular re...

Korea and U.S. reportedly in talks to jointly build 8 large-scale nuclear power plants in the U.S.

According to the South Korean government and political figures on September 7, South Korea and the United States are in the final stages of discussions on a plan to jointly build up to 8 large-scale nuclear power plants in the U.S. The plan is seen as one of the follow-up projects under the Korea-U.S. investment arrangement in the U.S. Sources say the U.S. side had proposed allocating $120 billion of the $200 billion investment commitment to the construction of 8 nuclear power plants within the framework of investment in the U.S. An additional $150 billion in shipbuilding-related investment falls outside that commitment. However, the South Korean government reportedly did not accept the proposal to directly specify the exact investment amount, instead preferring to use general wording such as "jointly building 8 nuclear power plants" in relevant documents to preserve room for further coordination...
