Publications, 16 August 2021
We offer to your attention a preprint “Optimization of Automatic Power Control System of the IBR-2M Pulsed Reactor in the Presence of Instability” P13-2021-30 published by the JINR Publishing Department. The authors are Pepelyshev Yu. N., Sumkhuu D.
The paper presents the main results of computational and experimental optimization of the automatic power control system (AR) of the IBR-2M pulsed reactor in the presence of a high level of oscillatory instability. Optimization of the parameters of the AR made it possible to significantly reduce the influence of random and deterministic oscillations of reactivity on the noise of the pulse energy, as well as to sharply reduce the manifestation of the oscillatory instability of the reactor. As a result, the safety and reliability of operation of the reactor has increased substantially.
The investigation has been performed at the Frank Laboratory of Neutron Physics.
