Abstract

tn contrast to the structural materials of nuclear reactors, the radiation resistances of concretes used in biological shielding have not been sufficiently studied. A tendency has recently arisen for the preferential use of heat-resistant concretes in biological shielding instead of materials such as steel, cast iron, graphite, boron, etc., which are costly and in relatively short supply. In this paper we shall indicate the effect of reactor neutron irradiation on certain properties of Porland-cement and liquid-glass heat-resistant chromite concretes. The integral neutron flux used in this investigation was (2–2.4) x 1021 neutrons/cm2 and the irradiation temperature up to 550° C.

It was found experimentally that these concretes:retain quite high strength and elastic properties. The thermal conductivity and thermal expansion coefficient change very littte. It is concluded that such concretes may be recommended for use in the biological shielding of nuclear reactors.
