Abstract

In this paper

the feasibility of measuring α eigenvalue for a subcritical reactor in the present experiment condition by the pulsed neutron method is discussed. A new experiment method of measuring γ intensity in the subcritical system to gain α eigenvalue is raised and the validity of this method has been proved. The limitation of using the DPF DD and DPF DT neutron source is also discussed.
