造。A separator plate for isolating between the annular downcomer and the lower plenum between the inner wall surface of the reactor pressure vessel and the outer wall surface of the shroud; In the cooling water flow path structure of an internal pump boiling water reactor, the cooling water flow path structure of an internal pump boiling water reactor is equipped with a plurality of internal pumps that forcefully circulate water supplied from a water supply pipe into the reactor core from a downcomer via a lower plenum. A plurality of upper and lower through-holes are provided in the separator plate on a circumference that is approximately the same as the circumference of the internal pump, avoiding the installation position of the internal pump, and the diameter of the through-hole is larger than that of the through-hole. With the upper end plate and the lower end plate at both ends, and a guide disk having a diameter larger than the diameter of the through hole at the center, they are connected by a connecting member whose central axis position is longer than the distance between the upper and lower surfaces of the through hole. Connected valve bodies having a king-shaped overall longitudinal section are respectively installed in the through holes, and the upper end plate of the valve body has a plurality of upper and lower valve bodies that directly communicate with the through holes provided in the separator plate. Cooling water channel groove for an internal pump boiling water reactor characterized by having a through hole □ ′
Construction.
