On 20 April, 2024, after a serious, long illness, one of the veterans of our Institute and Laboratory Nikolay Alekseevich Gundorin passed away.

Nikolay Gundorin 26.04.1945 – 20.04.2024  

Nikolay Alekseevich started his career at FLNP JINR in 1971 after graduating from the Leningrad Polytechnic Institute. During his time at FLNP, he held the positions of engineer, researcher, senior researcher, deputy head of department and head of sector. Nikolay Alekseevich’s entire scientific career concerned precision gamma spectroscopy, techniques, equipment and its application in physical experiments. It was in such experiments at IBR-30 that hitherto unique experimental data were obtained on variations in the yields of fission fragments in the neutron resonances of 235U and 239Pu nuclei which his Ph.D. thesis was based on that he defended in 1995.

In the last years of his work at JINR, he studied the properties of delayed neutrons from the fission of transuranic elements, carried out experiments to study the effects referring to violation of spatial parity in neutron-nuclear interactions and took an active part in measuring the spectra of delayed neutrons and leakage neutrons from the massive uranium target “Quinta” within the framework of the collaboration “Energy and Transmutation”.

Nikolay Alekseevich is a co-author of more than 100 scientific articles and reports at international conferences. His papers have been more than once awarded FLNP prizes. Quite often, he was the supervisor of pre-diploma internships and theses of students from MEPhI, Voronezh State University, MIREA. In 2003, Nikolay Alekseevich was awarded Badge of Honour for his paper “Veteran of Nuclear Energy and Industry”.

FLNP Directorate, friends and colleagues of Nikolay Alekseevich express deep condolences to his family and friends on his passing.

Paying last respects to the deceased will take place on 23 April, 2024 from 1:00 AM to 2:00 AM in the funeral hall of the Medical Unit № 9
