Russian designers propose hybrid powerplant concept for small nuclear submarine

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.

First Application and Verification of Intelligent Monitoring and Adjustment System for Nuclear Power Plant Personnel Status at "Hualong One" Nuclear Power Plant

On September 4, CGN Engineering, in collaboration with Cangnan Nuclear Power, successfully completed the testing, verification, and on-site data collection of the Intelligent Monitoring and Adjustment System for Nuclear Power Plant Personnel Status at the San'ao Nuclear Power Base. The CGN Engineering departments participating in this testing and verification included CGN Design Institute, the National Key Laboratory of Nuclear Power Safety Technology and Equipment (hereinafter referred to as the National Key Laboratory), CGN Engineering Cangnan Project Department, and Huasheng Technology. This joint test marks an important milestone in the project's transition from technology research and development to engineering application, providing key technical support for the quantitative analysis transformation of human factors safety management in China's nuclear power industry. The system, built upon the personnel fatigue status monitoring principle prototype developed under the Intelligent Nuclear Power strategic special project, has been iteratively improved with continuous support from the Yangjiang Chuangbao High-tech Research Project and the National Key Laboratory research projects, and has now evolved into a mature product suitable for engineering and large-scale application. Previously, relevant functional modules of the system had been deployed and data collected in applications such as human factors verification in the main control room of Yangjiang Nuclear Power Base and simulator training at Taishan Nuclear Power Base. The on-site testing and data collection at the San'ao Nuclear Power Base further verified the system's environmental adaptability and reliability across multiple nuclear power base scenarios, laying a solid foundation for subsequent industry-wide promotion and application.

Russian Research Team Synthesizes Novel Metal-Organic Framework Material Capable of Immobilizing Radioactive Cesium

Russian Research Team Synthesizes Novel Metal-Organic Framework Material Capable of Immobilizing Radioactive Cesium

The Frumkin Institute of Physical Chemistry and Electrochemistry of the Russian Academy of Sciences has synthesized a novel metal-organic framework material containing neptunium and cesium atoms. Research shows that this material is insoluble in water, resistant to high temperatures and intense radiation, and can stably "lock" radioactive cesium within its own structure, offering new insights for research on radionuclide immobilization and radioactive waste treatment materials. Metal-organic framework materials are a class of materials with high porosity and controllable crystal structures, whose lattices are typically composed of metal atoms connected by organic molecules. Since their pore sizes and structures can be tuned at the molecular level, these materials can be used to adsorb gases or specific nuclides. However, compared with traditional adsorbents such as activated carbon...

U.S. Completes Mechanical Property Measurements of Irradiated HALEU TRISO Fuel Particles

U.S. Completes Mechanical Property Measurements of Irradiated HALEU TRISO Fuel Particles

Researchers at the U.S. Department of Energy's Oak Ridge National Laboratory (ORNL) have completed mechanical property measurements of irradiated high-assay low-enriched uranium (HALEU) TRISO fuel particles, providing new experimental data for the development and qualification of next-generation nuclear fuels. This is an optical cross-sectional image of an irradiated AGR-2 TRISO fuel particle in the Irradiated Fuels Examination Laboratory at Oak Ridge National Laboratory. Image credit: Oak Ridge National Laboratory, U.S. Department of Energy. TRISO fuel, or tri-structural isotropic fuel, features particles coated with multiple protective layers, typically including pyrolytic carbon layers and a silicon carbide layer. This structure provides strong fission product retention capability and is considered one of the key fuel options for advanced reactors, particularly high-temperature gas-cooled reactors. Understanding the property changes of these coatings after irradiation is a critical step in predicting fuel performance under reactor operating conditions.
