Russia's Rosatom Develops 15 RITM-200 Marine Nuclear Reactors for Icebreakers
Russia has successfully constructed 15 RITM-200 reactor units, with plans for 13 more, as reported by Rosatom chief Alexey Likhachev. These small-scale reactors, each with a thermal power output of 175 megawatts and a lifespan of at least 40 years, are designed for use in hard-to-reach areas, particularly for icebreakers operating in icy waters. The RITM-200's innovative design integrates the core and steam generators within a single pressure vessel, reducing the system's footprint by approximately one-third compared to traditional marine reactors. This compact design allows for enhanced operational capabilities, enabling Project 22220 icebreakers to adapt their buoyancy for navigating both deep ocean and shallow river environments. Looking ahead, Rosatom is adapting the RITM-200 for civilian energy applications, including the RITM-200N for land-based power generation in Yakutia and the RITM-200S for floating power stations. The company is also exploring micro-reactor technologies for remote areas, with projects like the Shelf micro-reactor and the Elena thermoelectric unit.

A-UT Robot: 30 Years of Underwater Inspections in Nuclear Reactors
The A-UT robot, resembling a giraffe, has been operational in Japan's nuclear power plants for 30 years. Developed by Mitsubishi Heavy Industries, it performs critical inspections inside reactor pressure vessels using ultrasonic probes, where human access is impossible due to radiation. This robot is essential for ensuring the integrity of reactor components that contain high-pressure, high-temperature water and nuclear fuel. Its ability to operate in hazardous conditions makes it an invaluable tool for maintaining safety in nuclear energy production, especially as Japan's nuclear sector begins to revive. Looking ahead, the A-UT's role is expected to grow as more nuclear reactors restart operations, including the Kashiwazaki-Kariwa Unit 6 in February 2026. The continued use of such robots highlights their importance in energy strategy, ensuring the safety of welds in environments that are too dangerous for humans.

Penn State Scientists Discover Cause of Corrosion Highways in Advanced Nuclear Reactors
Researchers at Penn State University have identified the reasons behind the formation of 'corrosion highways' in advanced nuclear reactors. By adjusting the atomic arrangement of structural metals, they can influence the corrosion rate and extent, which is critical as nuclear energy gains traction in the quest for low-carbon energy solutions. The significance of this research lies in its potential to enhance the safety and efficiency of molten salt reactors, which operate at much higher temperatures than conventional fission reactors. With temperatures reaching 1,500 degrees Fahrenheit (800 degrees Celsius), understanding corrosion mechanisms is vital to prevent safety risks associated with reactor vessel integrity. Looking ahead, the team aims to develop a high-length-scale model to predict how different alloy materials behave when exposed to molten salt. This advancement could lead to the design of safer vessels for molten salt reactors, addressing the corrosion challenges identified in their studies.
