Russian Researchers Develop High-Wear-Resistant Steel Sample for Nuclear Waste Processing

Novosibirsk State Technical University (NSTU) recently announced that Russian researchers have developed a steel sample with reinforcing elements. Experimental results show that the durability of this material is approximately 4 times that of 5KhNM tool steel currently used in nuclear power plant waste processing equipment. The research focuses on improving precipitation hardening steel structures. Precipitation hardening steel is a special class of alloy material that, after quenching and holding at specific temperatures, precipitates fine, hard particles within the steel, thereby enhancing strength and wear resistance. The researchers aim to replace existing 5KhNM tool steel with new high-strength alloys...

Second Ring of Steel Containment Vessel for Reactor Building of Unit 2 at Xudabao Nuclear Power Plant Successfully Hoisted into Place

At 9:57 on August 4, the second ring of the steel containment vessel (hereinafter referred to as CV Ring 2) for the reactor building of Unit 2 at Xudabao Nuclear Power Plant was successfully hoisted into place. The CV Ring 2 hoisted this time is the third ring segment of the steel containment vessel for Unit 2, with a hoisting weight of nearly 890 tons. During the assembly phase, the installation of multiple discipline items, including annular air ducts, steel structural annular corridors, and U-shaped supports for air turbulence, was completed simultaneously for this module, effectively reducing the risk of cross-operation interference in subsequent internal construction of the nuclear island. This approach fully leveraged the advantages of modular construction and effectively translated the concept of "modularize wherever applicable, prefabricate wherever installable" into tangible engineering outcomes. During the assembly and hoisting of CV Ring 2 for Unit 2, Liaoning Nuclear Power, in collaboration with...

National Standard Compiled by CNNC Mining and Metallurgy Technology Successfully Released

Recently, the national standard "Methods of Analysis of Uranium Ore Concentrate - Part 1: Determination of Uranium - Ferrous Sulfate Reduction - Potassium Dichromate Titration Method" (GB/T 11848.1-2026), compiled by CNNC Mining and Metallurgy Technology Group Co., Ltd. (Beijing Research Institute of Chemical Engineering and Metallurgy, CNNC), was officially released. With this, all 15 national standard methods for "Methods of Analysis of Uranium Ore Concentrate" (GB/T 11848.2-11848.16, implemented in May 2026) led by our company have been fully released. Uranium ore concentrate is an important intermediate product in the nuclear fuel cycle, with its core value lying in the uranium it contains. The determination of uranium content is a crucial link throughout the entire industrial chain from ore to nuclear fuel. This is not merely a simple compositional analysis, but a core step in ensuring economic benefits, product compliance, process safety, and conformity with international regulations. The control of impurity elements plays an important role in the uranium purification and conversion process. The determination of impurity elements is primarily aimed at meeting product control and quality assurance requirements, ensuring downstream process safety, and supporting nuclear safeguards and forensic traceability. The new series of analytical methods is better adapted to modern production processes and detection techniques.

Behind India's Nuclear Power Expansion: Where Does Radioactive Waste Go? Government Details Management Process in Parliament for First Time

India is rapidly advancing its nuclear power expansion, but the safe disposal of radioactive waste is the least-publicized challenge. The government has for the first time detailed in Parliament how it handles hazardous waste. In a written reply, the Department of Atomic Energy disclosed that all nuclear power plants in India generate an average of 0.15 cubic meters (approximately 150 liters) of solid radioactive waste per megawatt (MW) of capacity annually, including waste from operational and decommissioning phases, equivalent to about 1.5 household bathtubs in volume; radioactive waste quantities and disposal records are regularly reported to the Atomic Energy Regulatory Board (AERB). The operation and maintenance of nuclear power plants generate various types of radioactive waste, including spent filter cartridges, protective clothing, tools, equipment, and other items that come into contact with radioactive materials. Waste is categorized into gaseous...

After 25 Years, the Muon Wobble Puzzle Sees Key New Progress in Physics

For 25 years, precise measurements of how muons wobble in a magnetic field have been a major puzzle in particle physics. Early experiments showed a discrepancy between the measured value of the muon's g-factor and theoretical predictions, a difference once seen as a possible hint of unknown particles. Recent new theoretical calculations and experimental analyses have brought a new twist to this puzzle. The muon is a heavier cousin of the electron that precesses like a tiny magnet in a magnetic field. Its extra wobble is quantified by the muon g-2 coefficient. According to quantum theory, known particles and interactions influence this coefficient through fleeting quantum fluctuations, making muon g-2 a key test of the Standard Model...
