The neutron integral transport dynamic equation is presented on the basis of a fundamental theory analysis. The presentation of th is equation is a development of the neutron integral transport theory. It enable s the integral transport theory not only to solve the heterogeneous cell paramet er problems but also to solve reactor dynamic problems. Neutron integral transpo rt dynamic equation is a multi-group and multi-point (one sub-zone is one poi nt) dynamic equation. It is only a multi-point dynamic equation for single grou p problem. The multi-group and multi-point equation can be used to analyse the spectrum time variation in different points and the multi-point dynamic equati on can be used to analyse the space dependent neutron dynamic behavior. In the s econd part of this paper an application example of the integral transport dynami c equation is presented. The problem of composition of neutron generation time f or China Advanced Research Reactor (CARR) is analysed.
