South Korea Accelerates Safety Reviews of Long-Term Operating Nuclear Reactors and Advances Licensing of First Spent Fuel Dry Storage Facility

The Nuclear Safety and Security Commission (NSSC) of South Korea stated at its second-half work report meeting on August 4 that it will accelerate safety reviews of long-term operating nuclear reactors while simultaneously advancing regulatory efforts such as licensing systems for spent fuel dry storage facilities and small modular reactors. Under the plan, the NSSC will conduct safety inspections on nine reactors applying for continued operation, with review standards referencing newly built nuclear power plants and confirming safety margins in consideration of the characteristics of long-term unit operation. Among these, whether Kori Nuclear Power Plant Units 3 and 4 will be approved for continued operation in the second half of this year, and whether Hanbit Nuclear Power Plant Units 1 and 2 will be approved for continued operation in the first half of next year, are the near-term review priorities...

Kairos Power Advances Flibe Molten Salt Applications to Support KP-FHR High-Temperature Reactor Development

Kairos Power announced on July 29 that its Fluoride Salt-Cooled High-Temperature Reactor (KP-FHR) will be among the early adopters of a fluoride salt coolant. This coolant, commonly referred to as Flibe, is composed of lithium fluoride (LiF) and beryllium fluoride (BeF₂). In the 1960s, Oak Ridge National Laboratory used this material as a coolant in the Molten Salt Reactor Experiment. According to Kairos Power, Flibe has a high specific heat capacity, enabling it to effectively absorb and transfer heat generated in the reactor core. Compared with some sodium-cooled or helium-cooled reactor systems, fluoride salt offers certain advantages in heat transport...

Global Nuclear Power Construction Accelerates, Asian Countries Lead the Way

Global nuclear power construction is accelerating, particularly in the Asian region. China is currently the most active country in nuclear power construction worldwide, with more than twenty nuclear reactors under construction, far surpassing other nations. This large-scale investment reflects China's emphasis on energy security and reducing carbon emissions. India follows closely behind, also actively expanding its nuclear power capacity to meet growing electricity demand and achieve climate goals. Beyond Asia, several European countries are also increasing their nuclear power capacity. Although France already possesses a large number of existing nuclear power plants, it is also advancing the construction of new nuclear reactors, aiming to maintain the share of nuclear energy in its energy mix. The United Kingdom is likewise committed to developing nuclear power, with plans to build new...

Japan's Nuclear Plant Renewal Faces Labor Shortage Challenges

Japan is planning to replace its aging nuclear reactors to enhance the nation's energy independence. However, the key issue is that labor shortages are threatening the progress of this effort. According to reports, up to 70% of related companies have reported difficulties in recruiting personnel, placing greater strain on an already tight schedule. The government has approved plans to build up to five new nuclear reactors by 2040, but the human resource bottleneck at the operational level is becoming an increasingly serious problem. The labor shortage not only affects the progress of new projects but also puts pressure on the safe operation and maintenance of existing nuclear power plants. As aging reactors are gradually...

ZiaCore Microreactor Achieves Criticality in High-Temperature Zero-Power Experiment

Los Alamos National Laboratory announced on July 30 that its ZiaCore microreactor design has completed a high-temperature zero-power criticality proof-of-principle experiment at the National Criticality Experiments Research Center (NCERC) in Nevada, successfully achieving initial criticality. ZiaCore is an advanced nuclear energy microreactor design that uses low-enriched uranium dioxide fuel. The experiment lasted approximately four weeks from April to May this year, advancing the ZiaCore system to zero-power criticality under high-temperature conditions. According to the reactor design and verification process, zero-power criticality experiments can be used to validate the effectiveness of reactor physics designs, providing key benchmark data for subsequent engineering development.
