Cold Functional Test of Tianwan Nuclear Power Plant Unit 8 Successfully Completed

On August 3, the cold functional test (hereinafter referred to as the "cold test") of Tianwan Nuclear Power Plant Unit 8, constructed by China Nuclear Industry 23 Construction Co., Ltd. (CNI23), was successfully completed, marking the official transition of the unit from the engineering installation phase to the system commissioning and testing phase, laying a solid foundation for subsequent hot functional test, reactor fuel loading, and grid connection. The cold test is the first comprehensive commissioning test after a nuclear power unit enters the system commissioning phase and is one of the important milestone nodes in nuclear power plant engineering construction. Its main purpose is to verify the integrity and leak-tightness of the pressure boundary, including primary loop pipeline welds, equipment, and high-pressure sections of connected systems, comprehensively inspect on-site installation quality, and precisely identify potential hazards. It serves as the first comprehensive and systematic "physical examination" of the reactor before its operation.

Unit 2 of Kola NPP begins 30-day scheduled preventive maintenance

On August 2, 2026, Unit 2 of the Kola Nuclear Power Plant launched scheduled preventive maintenance (SPM) incorporating modernization elements, expected to last approximately 30 days. During this mid-cycle overhaul, specialists will carry out extensive work on critical equipment. In the reactor shop, major repairs will be performed on part of the steam generators, main circulation pumps, and primary circuit piping. Plans also include disassembly and reassembly of the reactor plant, nuclear fuel replacement, and repair of the reactor internals and safety system equipment. In the turbine shop, turbine units, turbogenerators, circulation pumps, low-pressure heaters, and separators-superheaters will be repaired. On the electrical side, transformers and diesel generators will undergo maintenance.

Dominion Energy Renews Early Site Permit for North Anna Nuclear Plant

Dominion Energy Virginia is taking steps to renew the early site permit for its North Anna nuclear power plant, originally issued in 2007. Located in Louisa County, the North Anna plant currently operates two reactors. The company submitted an application to the U.S. Nuclear Regulatory Commission (NRC) on July 14, seeking to extend the early site permit for a period of 20 years, or 20 years from the date of issuance, whichever is later. The NRC has formally acknowledged receipt of the request and is reviewing it for docketing acceptance. An early site permit is an optional process through which the NRC can confirm whether a site is suitable for a new nuclear power plant; obtaining such a permit can reduce risks of delays during the licensing and construction process...

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...

Carbon isotope analysis reveals: Canadian Arctic seabed sediments can sequester part of permafrost organic carbon

News dated August 3, 2026: Researchers from the Alfred Wegener Institute and the Center for Marine Environmental Sciences at the University of Bremen conducted a study on permafrost coasts near Herschel Island (Qikiqtaruk) in Canada, finding that not all terrestrial organic carbon released by Arctic permafrost thaw and coastal erosion enters the atmosphere—a significant portion is instead stored in seabed sediments. The findings have been published in the journal *Nature Geoscience*. Arctic terrestrial permafrost ecosystems store approximately 130 billion tons of carbon from organic sources such as plant debris, while marine and river delta sediments contain an additional 40 billion tons. As Arctic warming accelerates...

Unveiling Extreme Heat: Z Boson Probes New Mechanisms of the "Hottest Matter in the Universe"

Using Z boson probes at the Large Hadron Collider (LHC), scientists have revealed new details about how the hottest matter in the universe—the quark-gluon plasma (QGP)—absorbs energy, challenging existing theoretical models. This research provides important clues for understanding the state of the early universe shortly after the Big Bang. To gain deeper insights into the QGP, physicists cleverly employ Z bosons as messengers. Since Z bosons do not interact with the QGP, they can traverse the plasma almost unaffected, precisely recording information about the initial state. By analyzing the momentum differences between μons produced from Z boson decays and their recoiling jets, scientists were able to determine the energy lost by quarks as they traverse the QGP...
