A large number of fuel assemblies 6.about.6... are arranged in a line between them to form a reactor core 7'li-. Furthermore, control rods 9 that are raised and lowered by a control rod drive mechanism 8 are inserted between the fuel assemblies 6 to control the output of the nuclear reactor. Furthermore, a plurality of jet pumps 1 are provided on the outer peripheral side of the core 7.

心７へ再循環される。A large number of steam and water separators 11 are provided above the upper grid plate 4.
, 11... are arranged to separate a mixture of steam and water boiled by the heat generated in the core 7. The steam separated by the steam separator 11 passes through an upper steam dryer 12 and is dried, and then is supplied to a turbine system (not shown) outside the pressure vessel 3 through an outlet nozzle 13. It looks like this. on the other hand,
The water separated by the steam separator 11 flows downward and is recirculated to the reactor core 7.
前述した気水分離器１１の従来のものは第２図に示すよ

いる。In FIG. 2, an intermediate cylinder 15 is disposed concentrically within an outer cylinder 14 having a triple-tube configuration, and a boss 16 is concentrically disposed within this intermediate cylinder 15. A plurality of twisted blades 17°17 are provided between the base 16 and the intermediate body 15.
are arranged in the circumferential direction. An outlet side 18 having a smaller diameter than the intermediate cylinder 15 faces the upper end of the intermediate cylinder 15 .
前述した構成によれば、中間胴１５の下端の入口部１９

設けられた外胴１４の排液部加によりすくい出される。According to the above-described configuration, the inlet portion 19 at the lower end of the intermediate barrel 15
The two-phase flow of steam and water flowing in is given a rotational force by the twisted blades 17. By the way, steam and water have different densities, and heavier water is subject to greater centrifugal force and is
Attach to the wall of 5. This adhered liquid is scooped out by a liquid drain section of the outer shell 14 provided at the upper part and outside.
一方、中心部にたまった蒸気は中間胴１５の上部の中央

れ出る。On the other hand, the steam accumulated in the center flows out from an outlet side 18 facing the center of the upper part of the intermediate shell 15 to an upper steam dryer (not shown).
ところが、このように構成された従来の気水分離器にお

た液滴は回転力を受けに＜＜、シたがって遠心力も弱く
、中間胴１５の壁に達するまでに、相当の距離を要し、
機器の大型化を招いていた。However, in the conventional steam/water separator configured in this way, the droplets that flowed near the center of the inlet section 19 adhere to the center boss section 16, and furthermore, the droplets that flow near the center of the inlet section 19 adhere to the center boss section 16, and furthermore, the droplets that have a steep area at the terminal end (upper end) of the two slots 16. Due to the low pressure behind the boss portion 16 as it expands, it is rolled into the center. The droplets caught in the center are subject to rotational force, therefore the centrifugal force is weak, and it takes a considerable distance to reach the wall of the intermediate barrel 15.
This caused the equipment to become larger.
この発明は、このような点に鑑み、中間胴の中心部に巻
き込まれた液滴に対し回転力を与えて遠心力を強くし、
中間胴を短く形成し得る気水分離器を提供することを目
的としている。In view of these points, this invention applies rotational force to the droplet caught in the center of the intermediate barrel to strengthen the centrifugal force.
It is an object of the present invention to provide a steam/water separator in which the intermediate shell can be formed short.
この発明による気水分離器は、中間胴内に同心状にボス

シ羽根の上方に副ひね９羽根を設けたものである。The steam/water separator according to the present invention has a boss disposed concentrically within the intermediate shell, and nine auxiliary spin blades provided above the twist vanes disposed between the boss and the intermediate shell. .
以下、仁の発明を図面に示す実施例により説明する、な
お、前述した従来のものと同一の構成については、図面
中に同一の符号を付し、その説明は省略する。Hereinafter, Jin's invention will be explained with reference to embodiments shown in the drawings. It should be noted that the same components as the conventional one described above are denoted by the same reference numerals in the drawings, and the explanation thereof will be omitted.

At the upper end of this central shaft 21, there are a plurality of sub-deflecting blades n, 2.
2... are provided so as to protrude toward the outer circumferential side.

The closed droplet flow shows a different aspect from the conventional one. That is, after passing through the knife 16, these droplets are sucked up to the rear central part of the boss 16, but because the sub twisting blade η is present in that part, the droplets in the central part are Rotational force is applied again, and the movement starts toward the wall of the intermediate cylinder 15. By re-accelerating in the direction of the intermediate barrel 15 in this manner, the separation of air and water is completed extremely quickly. The separated droplets are dropped through the inner space of the outer shell 14 made of double cylinders and the annular path between the outer shell 14 and the intermediate shell 15,
Refluxed into the reservoir coolant.

できるという優れた効果を奏する。As explained above, since the steam/water separator according to the present invention is provided with the sub-twisting blades above the twisting blades, it is possible to provide a high-performance and miniaturized steam/water separator. This has an excellent effect in that the support and combined structure of this part of the reactor can be made smaller, and the cost required for constructing the reactor can also be reduced.
