The measurements of the total delayed neutron yield from fast neutron induced fission of 238U were made. The experimental method based on the periodic irradiation of the fissionable sample by neutrons from a suitable nuclear reaction had been employed. The preliminary results on the energy dependence of the total delayed neutron yield from fission of 238U are obtained. According
to the comparison of experimental data with our prediction based on correlation properties of delayed neutron characteristics, it is concluded that the value of the total delayed neutron yield near
the threshold of (n,f) reaction is not a constant.
