Interview with Aleksandr Selyunin, a head of the project "Development of deep tissue oxygenation measurement systems using time-domain diffuse optics" that received financial support within the JINR competition

In August 2025, a youth team from the Laboratory of Nuclear Problems, led by Aleksandr Selyunin, received financial support for their project within the JINR competition for research & development projects with high potential for implementation in industry, scientific instrumentation, and the social sphere.

Results of the International Partnership Program Award of the Chinese Academy of Sciences announced

On 1 September, 2025, the head of the Sector of Reactor Neutrinos of the Department of Particle Physics, Maxim Gonchar together with his Chinese colleague Zhan Liang were awarded the International Partnership Program Prize of the Chinese Academy of Sciences.

Data acquisition starts at the JUNO experiment

On 26 August 2025, the international collaboration of the JUNO experiment officially announced the completion of filling the central detector with 20 thousand tonnes of liquid scintillator at the Jiangmen Underground Neutrino Observatory on the south of China. The collaboration also started the detection of physical events. The aim of the experiment is determination of the hierarchy of neutrino masses and precision measurement of neutrino oscillation parameters.

Long term remote reactor power and fuel composition monitoring using antineutrinos

In July 2025, a new paper titled "Long term remote reactor power and fuel composition monitoring using antineutrinos" was published in Physics Letters B. It presents the results of seven years of antineutrino flux measurements from a nuclear reactor at the Kalinin Nuclear Power Plant in the DANSS experiment. DLNP staff members play a key role in the experiment, ranging from the development of the first detector prototypes to ensuring the described long-term measurements at the Kalinin NPP.
