The prospects of studying ternary nuclear fission in horizontal channel No. 1 of the VVR-K reactor.

Abstract

The article discusses the study of rare nuclear fission mechanisms, such as ternary and quaternary fission, which occur during both spontaneous and induced fission by neutrons. Our group previously conducted experiments to investigate the ternary and quaternary spontaneous fission of the isotope ²⁵²Cf. The next stage is to study ternary fission during induced fission by neutrons.

Steps have been prepared for conducting research on ternary fission under neutron irradiation, including the creation of an experimental setup and the development of particle detection methods. Test measurements were carried out at the VVR-K reactor in Almaty. Experiments with the ²³⁹Pu target provided valuable methodological results that significantly impact the accuracy of subsequent studies. The conclusions of the experiment confirm the need to revise technical solutions to achieve high standards of accuracy and reliability in research.
