Russian designers propose hybrid powerplant concept for small nuclear submarine

Nikolai Kirillov, a designer from St. Petersburg, Russia, has proposed a powerplant concept for a small nuclear submarine, envisioning a combination of a diesel engine, a small nuclear reactor, and an electric motor to provide the submarine with three operating modes: diesel surface cruising, electric submerged navigation, and sustained nuclear power generation. Under this concept, the submarine is powered by the diesel engine while surface cruising. The diesel engine drives a fixed-pitch propeller through a gearbox and a dedicated propeller shaft, allowing the diesel to operate as close to its rated conditions as possible to reduce equipment wear. In submerged conditions, the diesel engine is shut down, and propulsion is provided by a separate electric motor. This motor is paired with a controllable-pitch propeller and draws power from a battery bank.

Europe Advances Space Nuclear Power Research, Targeting Lunar and Mars Missions

The European Space Agency (ESA) is accelerating its assessment of nuclear energy applications in deep-space missions, focusing on using small nuclear reactors to power spacecraft electric propulsion systems, as well as providing stable energy for future fixed lunar surface facilities and subsequent Mars missions. Existing space missions primarily rely on chemical fuels and solar panels. The former is limited by the amount of propellant that can be carried, while the latter suffers from declining power generation efficiency as spacecraft move farther from the Sun. ESA believes that nuclear power systems could compensate for the shortcomings of both approaches, particularly in long-duration lunar operations and deeper space exploration. ESA completed a nuclear thermal propulsion study last year. In March this year, the agency...

Russia Plans to Build Small Nuclear Power Plant in Kyrgyzstan, Land-Based Icebreaker Reactor in Focus

Rosatom's plan to promote the construction of a small nuclear power plant in Kyrgyzstan is centered around discussions on the RITM-200N reactor design. With a power output of approximately 55 MW, this reactor is the land-based version of the RITM-200 reactor used in Russia's new generation of nuclear-powered icebreakers. Several Russian nuclear-powered icebreakers currently operate on the same technological platform, which serves as the primary basis for Russia to demonstrate its maturity and reliability. The project first entered public discussion in January 2022. At that time, Kyrgyzstan's energy authorities stated that if a nuclear power plant were to be built, its installed capacity should be no less than 300 MW, reflecting the country's practical concerns over power shortages and energy security...

Heat Exchangers and Mechanical Filters for Russian Nuclear-Powered Icebreakers Complete Testing

On August 11, 2026, the manufacturing project for equipment supporting Russian nuclear-powered icebreakers achieved a milestone. InterPolaris has completed testing of multiple key equipment items, including two shell-and-tube heat exchangers and two mechanical filters. The shell-and-tube heat exchangers that completed testing this time are primarily used to heat water containing purification solutions using heating steam. Compared with conventional heat exchange equipment, the operating environment of marine nuclear power platforms is more complex, imposing higher requirements on structural strength, sealing performance, and operational stability. The horizontal heat exchanger is designed to accommodate prolonged vessel inclination conditions, with mounting brackets capable of withstanding loads from different directions and maintaining stable equipment parameters under complex operating conditions.

Russian Company InterPolaris Completes Testing of Heat Exchangers and Mechanical Filters for Nuclear-Powered Icebreakers

Russian company InterPolaris has achieved a significant milestone in the manufacturing project of equipment for nuclear-powered icebreakers, successfully completing tests on two shell-and-tube heat exchangers and two mechanical filters. These units are designed for the specific operating environment of nuclear-powered icebreakers, and passing the tests means the products meet design requirements in terms of strength, sealing, stability, and long-term service capability. The shell-and-tube heat exchangers that passed verification are primarily used to heat water containing decontamination solutions using heating steam. Although this is a common heat exchange process in principle, in the icebreaker application scenario, the equipment must meet requirements far exceeding ordinary industrial standards. This horizontally arranged equipment is designed with consideration for continuous operation under prolonged ship listing conditions, with fixed structures capable of withstanding loads from various directions, and is required to maintain stable parameters and reliable sealing under complex sea conditions and operating regimes.

Russian Nuclear-Powered Icebreaker "Yakutia" Provides First Escort for Luxury Cruise Ship to Wrangel Island Nature Reserve

This summer, the second group of tourists to Wrangel Island successfully landed on the nature reserve. 150 tourists were able to witness with their own eyes this mysterious island known as the "birthplace of polar bears." This was made possible thanks to the nuclear-powered icebreaker Yakutia providing ice escort services for the luxury cruise ship SH Minerva, ensuring navigational safety. This year, ice conditions in the Chukotka region were relatively complex, posing challenges to the cruise ship's operations. Previously, SH Minerva had failed to reach Wrangel Island due to its inability to break through sea ice, so the trip organizers took special measures this time. RussiaDiscovery and Vodokhod companies submitted a request to Rosatomflot...
