Glembotskii, A. Degtyarev, A. Myasnikov, T. Trofimova, A. Sobolev, S. Sorokin] The simplest approximations (one-dimensional reactor, single-group diffusion model of neutron transfer) are used to study the characteristics of xenon oscillations in a reactor with negative feedback on the coolant temperature. It is shown that in this case, in contrast to the situation where the predominant feedback is on the neutron flux density, the emergence into the xenon instability regime will manifest in the form of perturbations of the reactor power and energy release simultaneously. In addition, the deformations of the energy-release field grow with increasing neutron flux and physical dimensions of the reactor. Springer Science+Business Media New York, 2015 Glembotskii A.
