Amid Russia’s invasion, Ukraine’s three operating nuclear plants—Rivne, South Ukraine, and Khmelnytskyi—continue powering the country yet face elevated danger from occupation and attacks; Rivne has tightened safety drills, Zaporizhzhia remains under occupier control, and repair work at Chornobyl’s New Safe Confinement is urgent, even as Ukraine pursues modernization with Western help.
In the 1990s, the Chornobyl Nuclear Power Plant modernized its remaining RBMK reactors not by a full rebuild of the Soviet-era mainframe, but by wrapping a new auxiliary information-measurement system (DIIS) around the 1970s SKALA mainframe. The upgrade linked a Ukrainian SM-1210 minicomputer and an ARCnet-connected 80386 PC to run real-time reactor-core modeling and visualization via the PRIZMA program, letting data stay local instead of being sent to Moscow. Unit 2 operated until 1991 (turbine fire), Unit 1 until 1996, and Unit 3 until 2000, yielding a pragmatic, hybrid upgrade that pushed the plant toward 21st-century capabilities.
IAEA Director General Grossi says renewed military activity disrupted Ukraine’s power grid, impacting nuclear power plant operations including a temporary loss of off-site power at Chornobyl and reduced output at other NPPs. Three IAEA teams are inspecting 10 substations over two weeks to assess damage, coordinate repairs, and strengthen resilience, marking the second such mission in months; the agency reiterates calls for restraint and adherence to safety pillars.
Stalker 2: Heart of Chornobyl is now available for pre-download on Xbox Series X|S, with a massive file size of 146.5GB, ahead of its November 20 release. The game, set in the Chornobyl Exclusion Zone, offers an open-world experience where players manage resources and explore over 20 regions. It will be available on Xbox Game Pass and supports mods on Xbox.
A new study led by researchers at New York University finds that microscopic worms living in the Chornobyl Exclusion Zone have not suffered genetic damage from chronic radiation exposure, suggesting exceptional resilience. The study, which focused on nematodes, revealed that the worms did not show a genetic signature of radiation damage, and their tolerance to DNA damage did not correspond to radiation levels. The findings provide insights into DNA repair and genetic variation, potentially aiding cancer research and our understanding of individual risk factors.
Wolves in the Chornobyl Exclusion Zone, exposed to high levels of radiation since the 1986 nuclear disaster, have developed an unexpected immunity to cancer. Research has shown that their immune systems have adapted similarly to cancer patients undergoing radiation therapy, with genetic changes providing protection from the disease. Scientists are now working to identify the specific mutations responsible, which could potentially aid in the fight against cancer in humans. However, ongoing safety concerns due to Russia's invasion of Ukraine have temporarily halted further research in the area.
