Procedure for Taking into Account the Influence of the Neutron Field on Reactivity Effects in Engineering Calculations
摘要
Abstract
In order to improve the accuracy of engineering calculations in the design of marine reactor installations with high energy resources, characterized by significant values of reactivity coefficients related to the coolant and axial offsets, a preliminary study of the method for refining the dependence of the reactivity density effect on the nature of the neutron field distribution has been carried out. The necessity of validating the methodology on the basis of comparing calculated and experimental natural temperature dependences is noted.
