物。 A lower core support plate is attached to the lower end of the reactor core barrel so as to close the lower end opening of the reactor core barrel and is supported at the lower part of the side wall of the reactor vessel. In the lower core structure of a nuclear reactor, the lower core support plate is provided with one manhole hole having an inner diameter larger than the inner diameter of the passage hole, wherein the lower core support plate has one manhole hole having an inner diameter substantially the same as the inner diameter of the passage hole. A lower core structure for a nuclear reactor, characterized in that an orifice plate having a hole is attached to the manhole hole of the lower core support plate.
