摘要： PURPOSE:To contrive large enlargement of nuclear reactor output by equipping a plurality of reactor core vessels housing independent reactor cores in a nuclear reactor vessel and an intermediate cooler for heat-exchanging a primary coolant for a secondary coolant. CONSTITUTION:When a nuclear reactor is started, a primary coolant 26 is supplied to a reactor core vessel 31 through an inflow nozzle 36 from a high pressure plenum 29 in the lower part of a nuclear reactor vessel 25. Heating is performed due to nuclear reaction heat at the time when the coolant 26 passes reactor cores 35 in each vessel 31 and it is discharged from an outflow port 37 to an upper plenum 28. A primary coolant of high temperature guided to a plenum 28 is guided to an intermediate heat exchanger 45 from an inflow port 48 of an intermediate cooler 32 and passes through the tube bundle of the heat exchanger 45. At the time the primary coolant is heat-exchanged for the secondary coolant and cooled therewith. The secondary coolant heated with the exchanger 45 is transmitted to a steam generator 51 through an inflow and outflow tube 52 and feed water is heated.

摘要： PURPOSE:To simplify the structure and improve the maintainability and the approachability of an operator in maintenance by circulating a primary cooling material and a secondary cooling material without using cooling material tubing. CONSTITUTION:The primary cooling material which is heated by a reactor core flows in an intermediate heat exchanger 32 through a primary high temperature pool 29 and exchanges heat with the secondary cooling material in the exchanger 32 and is sent to a primary low temperature pool 30. The primary cooling material in the pool 30 is sucked by a primary cooling material electromagnetic pump 3 and sent to the reactor core 27. The secondary cooling material heated in the exchanger 32, on the other hand, is discharged from the upper end of the exchanger 32 to a secondary high temperature pool 39 to flow in a steam generator 41 and exchange heat with water from a feed water pipe 4. Superheated steam produced by the heat exchanging is sent to a steam turbine through a superheated steam tube 43 and the secondary cooling material which drops in temperature by the heat exchanging is sent out to a secondary low temperature pool 40. The secondary cooling material in the pool 40 is sucked by a secondary cooling material electromagnetic pump 36 through a through holes 37 and sent in the exchanger 32.

摘要： PURPOSE:To shorten the construction period of a prefabricated nuclear power plant by omitting the field erection of the plant. CONSTITUTION:The outer peripheral area of a reactor container is partitioned into several units on a nuclear reactor building base mat 11 and steel boxes in which equipment, piping and electric components to be disposed in each unit are stored are fabricated as first to sixth unit modules 1-6 in a factory. The unit modules 1-6 are installed on the nuclear reactor building base mat 11 at a construction site. The boxes facing the reactor container are joined together and the reactor container is covered at its upper side with confinement modules 7-9 and the confinement modules 7-9 are placed on the box walls of the unit modules 1-6 and joined together. During the process of installing the unit modules 1-6 a nuclear reaction module 12 with which the reactor container and a reactor core main body are fabricated integrally is installed on the nuclear reactor building base mat 11. The unit modules 1-6, the confinement modules 7-9, and the nuclear reactor module 12 are installed on the nuclear reactor building base mat 11 and are joined together and then the work of connecting piping and electrical wiring among the modules is performed.
