A Pulsed Reactor

Abstract

The design of a pulsed reactor using ordinary water and enriched uranium is presented together with a method of computing the physical and thermal parameters. Very stable heat production during the neutron bursts can be ensured, provided certain conditions are fulfilled. Calculations show that the suggested design can provide a thermal power of ≳5 MW with a mean neutron flux in the core ≳ 10¹⁴ neutrons.cm⁻². sec⁻¹ and a peak flux during the burst of about 10¹⁷ neutrons.cm⁻².sec⁻¹.
