MIPT and U.S. Partners Develop Precise Method for Calculating Nuclear Power Plant Seismic Resistance

Recently, the Science Communication Center of the Moscow Institute of Physics and Technology (MIPT) reported that Russian and American researchers have jointly developed a method capable of precisely calculating the seismic resistance of nuclear power plants, taking into account the heterogeneous structure of reinforced concrete, including the presence of individual rebar within walls and domes. The new method helps improve nuclear power plant safety by accounting for differences in how different types of seismic waves act on reinforced concrete. Alena Favorskaya, a lead researcher at MIPT, stated that the study explicitly identifies metal rebar as heterogeneities in the computational domain rather than averaging them; the grid-characteristic method (gr...

US-based Terrestrial Energy Proposes Phased Construction Model to Accelerate Deployment of 390 MW Integrated Molten Salt Reactor

Fourth-generation advanced nuclear developer Terrestrial Energy has recently formally submitted to the U.S. Nuclear Regulatory Commission (NRC) a topical report for the Thermal and Electric Facility (TEF) of its Integrated Molten Salt Reactor (IMSR) project. The document proposes a dual-track regulatory review model aimed at allowing key non-nuclear power components of the plant to proceed with construction and enter commercial operation before a full nuclear facility license is obtained. If this regulatory approach is approved by federal regulators, it will effectively break through the economic and approval obstacles that have long constrained the development of the nuclear power industry. In traditional nuclear power projects, because regulatory...

U.S. Department of Energy Deputy Secretary Visits Three Mile Island Nuclear Plant, Targeting Official Restart and Grid Connection in 2027

The Deputy Secretary of the U.S. Department of Energy (DOE) recently conducted an on-site inspection of Unit 1 at the Three Mile Island Nuclear Plant in Pennsylvania. As the core platform for the plant's restart plan, the renamed Crane Clean Energy Center is currently pushing forward engineering preparations at full speed, with the goal of officially restarting and connecting to the grid in 2027. Facing rapidly rising baseload power demand in Pennsylvania and across the entire Mid-Atlantic region, the restart project has secured more than $1 billion in federal dedicated investment and policy-based financial support. Three Mile Island Unit 1 was retired early in 2019 due to insufficient market economics under the impact of natural gas power generation at the time...

U.S. NRC Expedites Review of License Amendment for Palisades Nuclear Plant Fuel Loading Tilt Incident: Advancing Vanguard SMR Construction Permit Review in Parallel

The U.S. Nuclear Regulatory Commission (NRC) is reviewing an emergency operating license amendment request (LAR) submitted by Holtec International. The request was triggered by a nuclear fuel loading tilt incident at the Palisades Nuclear Power Plant (Palisades NPP) in Covert, Michigan, during its restart process, which has resulted in the temporary suspension of some on-site restart recovery operations. According to the application documents publicly available in the NRC's public records system, fuel assembly number DD41 tilted after being released by the fuel handling machine. The lower nozzle of the assembly remains in the core grid position H-1, but the upper portion forms an approximately 30-degree tilt angle with the core plate...

Controversy Over U.S. Nuclear Waste Repository Siting Draws Renewed Attention: Historical Decision Alleged to Have Relied Excessively on Cost Estimates

The issue of siting a U.S. nuclear waste repository has once again drawn attention. A reanalysis of the U.S. Department of Energy's (DOE) 1986 candidate site evaluation report points out that the key factor determining the priority siting of a nuclear waste repository at that time was not fully verified differences in long-term safety performance among the sites, but mainly estimates of repository construction and operating costs and spent fuel transportation costs. This analysis argues that the relevant cost data had considerable uncertainty, yet played a decisive role in the final ranking, causing the technical evaluation to present a clearer ordering of advantages and disadvantages than the actual evidence supported. The debate over U.S. nuclear waste repository siting has lasted for decades. The 1982 Nuclear Waste Policy...
