| Abstract: | The influence of the parameters of a research reactor on the thermal-neutron flux in the reflector and the cost of the fuel required is considered. It is shown that, the higher the neutron breeding factor and the smaller the radius of the active zone, the greater is the ratio of the maximum thermal-neutron flux to the reactor power, This ratio is in particular quite large for reactors of the water-cooled, water-moderated type operating with intermediate neutrons. From the point of view of minimum fuel cost in experimental reactors, it is undesirable to choose either very low or very deep burnup.Translated from Atomnaya Énergiya, Vol. 21, No. 2, pp. 97–101, August, 1966. |
