ほう耐水をポンプ４で、原子炉ｌの中に注入するように
しである。That is, in FIG. 1, reference numeral 1 denotes an ih'+f- reactor, and a crawling water-resistant storage tank 4 is connected to this reactor 1 through a pump 3 and a conductor f1'r2G. , if the primitive reactor l cannot be stopped with the control rods in the normal primitive reactor i, or if it becomes necessary to perform an emergency shutdown, the pump 4 Then, it is to be injected into the nuclear reactor.
一方、前記はう融水貯蔵タンク４には、前述のように、
はう耐水の温度を所定温度以上に保持するため、加熱装
置を装備しＣいる。On the other hand, the creeping melt water storage tank 4 has, as mentioned above,
In order to maintain the temperature of creeping water above a predetermined temperature, a heating device is installed.

ンク内に吐出させる。On the other hand, the air pipe 2
0 is provided, and compressed air is discharged from the air hole 21 into a small storage tank for fluoric acid.
ここで、隔離管内の空間】Ｏが空気で充填されている場
合、空気の流動がほとんどなく、ヒータ７が過熱される
恐れがある。Here, if the space [O] inside the isolation tube is filled with air, there is almost no air flow, and there is a risk that the heater 7 will be overheated.
一方、空間１０に液体を入れると静止空気より熱伝達が
向上し、ヒータの過熱は静止空気のときより発生頻度は
少なくなるが、ヒータの故障時に液体処理が必要である
という欠点があった。On the other hand, filling the space 10 with liquid improves heat transfer compared to still air, and overheating of the heater occurs less frequently than with still air, but it has the disadvantage that liquid treatment is required in the event of heater failure.
本発明の目的は、前記のようにほう耐水の加熱及び保温
