よとすると、原子炉容器(1)を可能な限り小型化する
必要があるが。Since the outer container of the intermediate heat exchanger (4) is cylindrical, an unused space is created around it as shown by diagonal lines in FIG. Also, as shown in Figure 13, many intermediate heat exchanger (4) supporting ribs (6) are welded to the intermediate heat exchanger (4) and the roof slab (5), so... FL contact work and inspection are troublesome. Moreover, the reactor vessel (1) is a large structure with a diameter of over 20 meters and a height of over 20 meters, and it is difficult to ensure earthquake resistance with the reactor vessel (1). However, it is necessary to make the reactor vessel (1) as small as possible.
原子炉容器(1)の直径及び高さは、主として中間熱交
換器(4)の直径及び高さに左右されるので。Since the diameter and height of the reactor vessel (1) mainly depend on the diameter and height of the intermediate heat exchanger (4).
中間熱交換器(4)の小型化が強く望まれている。There is a strong desire to reduce the size of the intermediate heat exchanger (4).
また原子炉容器(1)の耐震性を向上させようとすると
、原子炉容器(1)の板厚を厚くしてもよいが。Furthermore, in order to improve the earthquake resistance of the reactor vessel (1), the plate thickness of the reactor vessel (1) may be increased.

題があった。In that case, the temperature of the coolant coming out of the core (2) is approximately s
oo'c is very high, and there is a large temperature difference between the reactor vessel (1) part that touches the high-temperature coolant below the liquid level and the reactor vessel (1) part that does not touch the high-temperature coolant above the liquid level. As a result, there was a problem in that excessive thermal stress was generated in the reactor vessel (1).

供する点にある。It has a reactor core disposed in the reactor core tank, a roof slab that closes the top of the reactor vessel, and a coolant circulation pump suspended from the roof slab between the reactor vessel and the reactor core tank. In the nuclear reactor, a partition wall is erected between the core tank and the coolant circulation pump to form a heat exchange area between the core tank and the partition wall, and a tube bundle suspended from the roof slab is formed. The present invention relates to a nuclear reactor characterized by being located in a heat exchange region, and its purpose is to downsize the reactor vessel.

In a nuclear reactor having a roof slab that closes an upper part of the reactor vessel, and a coolant circulation pump suspended from the roof slab between the reactor vessel and the core tank, A partition wall is erected between the pump and a heat exchange area between the core tank and the partition wall, and the tube bundle hanging from the roof slab is located in the heat exchange area. The discharged high-temperature coolant flows from the core tank to the heat exchange area, flows there as extra-tube fluid, heats the intra-tube fluid flowing inside the tube bundle, and then returns to the core via the coolant circulation pump. There is no need for a heat exchanger, and the wasted space around the intermediate heat exchanger is eliminated, making the reactor vessel more compact. Also, since the low-temperature coolant only touches the reactor vessel after heat exchange,
1. The reactor vessel is maintained at a temperature below 425"C;
Excessive thermal stress in the reactor vessel is eliminated.
また中間熱交換器が無くなるので、原子炉容器が小型化
