Unit 4 of Slovakia's Mochovce Nuclear Power Plant Reaches First Criticality

Slovenské Elektrárne stated that Unit 4 of the Mochovce Nuclear Power Plant reached first reactor criticality at 22:10 local time on August 6, and achieved minimum controllable power at 22:31. This is a key milestone in the pre-commissioning work of the unit, indicating that the reactor is ready for subsequent testing. First criticality refers to the first time the nuclear fuel in the core achieves a self-sustaining fission chain reaction. Slovenské Elektrárne stated that first criticality and reaching minimum controllable power are important steps in the commissioning process of a nuclear power plant, used to confirm the unit's readiness to enter the next phase of testing...

JINR delegation participates in the 51st Vietnam Conference on Theoretical Physics

From August 3 to 6, the 51st Vietnam Conference on Theoretical Physics (VCTP-51) was held in Nha Trang, Vietnam. A delegation of researchers from the Bogoliubov Laboratory of Theoretical Physics and the Laboratory of Information Technologies of the Joint Institute for Nuclear Research attended the conference, engaging in exchanges with more than 170 scholars from Vietnam, Germany, India, China, Pakistan, Russia, Taiwan, the Philippines, Japan, and other countries and regions. The conference topics covered multiple frontier directions in theoretical physics, including high-energy physics, nuclear physics, condensed matter physics, and cosmology, as well as interdisciplinary research areas such as physics beyond the Standard Model, molecular physics, quantum optics and quantum information, biomaterials, and biomolecules. The broad agenda...

Hungary's Paks Nuclear Power Plant Avoids Full Shutdown as Danube Rises 2 cm, Now Operating at Only 240 MW

From the night of August 4 to the early morning of August 5, Hungary's Paks Nuclear Power Plant (about 100 km south of Budapest, commissioned in 1982, never fully shut down in its history) nearly disconnected from the grid due to low Danube water levels—3 of its 4 units had been sequentially shut down, leaving only one turbine operating at about 240 MW (normal output near 2,000 MW), supplying roughly half of Hungary's electricity. Hungarian Prime Minister Péter Magyar stated that the river level rose about 2 cm overnight, allowing the final unit's cooling to be maintained and averting the first full shutdown in 44 years; temperatures are still expected to exceed 40°C in the coming days, with cooling and rainfall only anticipated around Friday (approximately August 8). To alleviate energy pressure, Prime Minister Magyar thanked those who voluntarily...
