Abstract

The paper investigates the phenomenon of transverse bending of rod fuel elements of the active zone under the influence of temperature, which plays an important role in the dynamics of a periodic pulse reactor. Analytical calculation of thermoelastic deformation showed that positive feedback is directly related to the method of fixing the fuel elements. The possibility of fixing, eliminating the positive effect of reactivity, is demonstrated, and ways of technical solution of the problem are proposed.
