リウムガス冷却用熱交換器を設けているので。A secondary helium gas cooling heat exchanger is provided within the center pipe (43) of the intermediate heat exchanger.
耐熱二重配管がなくなって、低温配管のみになる。Heat-resistant double piping will be eliminated, and only low-temperature piping will be used.
また熱利用系に接続する場合には、第５図に示すように

換器のセンターパイプ（４３）に接続する。In addition, when connecting to a heat utilization system, as shown in Figure 5, the secondary helium cooling heat exchanger is separated from the center pipe (43) of the intermediate heat exchanger, and the piping of the heat utilization system is connected to the intermediate heat exchanger. Connect to the center pipe (43).

に設けたので、構造が複雑な。(Effects of the Invention) As described above, the high temperature gas reactor of the present invention has a plurality of systems of heat exchangers integrally provided in the reactor vessel, and each circulator of each heat exchanger system is connected to the reactor vessel. The structure is complicated because it is installed on the outer surface of the housing that is connected to the housing.

上記のように二重配管を不用にできる点と相撲ってコス
トを低減できる効果がある。It also eliminates the need for double piping made of expensive heat-resistant metal. In addition, as the heat exchangers of multiple systems are integrally installed in the reactor vessel as described above, the space for installing the heat exchangers of each system can be saved, and the containment vessel and building can be downsized.
This has the effect of reducing costs in combination with the fact that double piping can be dispensed with as mentioned above.
