Abstract

A pressure tube type nuclear reactor arranged in such a manner that pressure tubes each of which accommodates nuclear fuel and through each of which a coolant passes are accommodated in respective calandria tubes disposed in a calandria tank which contains heavy water, wherein the pressure tubes are arranged so as to form an equilateral triangular lattice configuration and/or a member, which replaces heavy water positioned around the calandria tube, is positioned around the calandria tube. Therefore, the volume ratio of nuclear fuel to heavy water can be made a proper value with which the coolant void reactivity coefficient becomes closer to negative values so that the self-control performance of the pressure tube type nuclear reactor is improved.
