発電用原子炉の設置と耐震性の問題 (制震系原子炉に関する若干の考察)

Abstract

An aseismic method for a British type nuclear power station proposed by oneof the authors was reported in the previous paper. The authors have believed thatit would be very difficult to design earthquake resistant reactors of this type withcomplete safety, without this aseismic method which transmits the action of adestructive earthquake motion as little as possible. In this paper, the theoreticalinvestigation on this method is still more developed and the following proposal forinstallation of various types of nuclear power stations is written. That is to say, the nuclear power station is to be located in rock of a peninsula. Major advantagesto be gained by this reactor installation may be listed as follows.1) The nuclear reactor located in rock is invulnerable to earthquake shocksand is not subject to disturbing surface phenomena such as typhoons, floods, etc.2) The reactor can ha located in a comparatively densely populated area.3) Effective containment in case of an accident can be obtained in rock excava-tion.
