本発明は原子炉容器壁冷却方式に係り、特に、炉壁全周
にわたる均一な冷却に好適なＦＢＲ原子炉容器に関する
。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a nuclear reactor vessel wall cooling system, and particularly to an FBR reactor vessel suitable for uniform cooling over the entire circumference of the reactor wall.
第１図に従来の原子炉構造図を示す。Figure 1 shows a structural diagram of a conventional nuclear reactor.
原子炉容器１の中に炉心２が置かれる。コールドプール
３のナトリウムは、ルーフスラブ４より吊シ下げられた
ポンプ５に吸い込まれ、高圧プレナム６に行き炉心２を
通り高温となってホットプール７に入シ、中間熱交換器
で熱交換した後、コールドプール３に戻る。A reactor core 2 is placed inside a reactor vessel 1 . The sodium in the cold pool 3 is sucked into the pump 5 suspended from the roof slab 4, goes to the high-pressure plenum 6, passes through the reactor core 2, reaches a high temperature, enters the hot pool 7, and undergoes heat exchange in an intermediate heat exchanger. Afterwards, return to Cold Pool 3.
従って原子炉容器１の上部温度は特別な配慮をしないと
、ホットグールアのナトリウムと同じ程度まで上がって
しまい、その温度は５００Ｃ前後にもなるため構造強度
上好ましくない。Therefore, unless special consideration is taken, the temperature of the upper part of the reactor vessel 1 will rise to the same level as that of sodium in hot glua, and the temperature will reach around 500C, which is not desirable in terms of structural strength.
そこで、従来は、原子炉容器１とホットプール７の間に
断熱構造９と冷却パス１０を設け、冷却パス１０には、
高圧ブレナム６内の低温ナトリウムを導いて対処してい
た。このナトリウムは、コールドプールのナトリウムを
ポンプで加圧したものでかつ、炉心を通さずにバイパス
させであるので、その温度は３５０Ｃ前後にまで冷却で
きる。Therefore, conventionally, a heat insulating structure 9 and a cooling path 10 are provided between the reactor vessel 1 and the hot pool 7, and the cooling path 10 has the following features:
The problem was dealt with by directing low-temperature sodium inside the high-pressure Blenheim 6. This sodium is pressurized from the cold pool using a pump, and is bypassed without passing through the reactor core, so its temperature can be cooled to around 350C.
ところで、例えばタンクｆｆ１ＦＢＲの場合、原子炉容
器径は２０ｍ以上もあシ、周方向温度の不均一による変
形等の害を避けるため、炉壁冷却方式には、均一冷却性
能が要求される。By the way, in the case of the tank ff1FBR, for example, the diameter of the reactor vessel is 20 m or more, and uniform cooling performance is required for the reactor wall cooling system in order to avoid damage such as deformation due to non-uniform circumferential temperature.
従来の冷却パス１０においては、その流路断面の一辺が
極端に長いという構造上、均一冷却に必要な均一流量の
確保が離しい。In the conventional cooling path 10, it is difficult to ensure a uniform flow rate necessary for uniform cooling due to the structure in which one side of the flow path cross section is extremely long.
本発明の目的は、周方向に同一な冷却性能を得られる冷
却方式を有する原子炉容器を提供することにある。An object of the present invention is to provide a nuclear reactor vessel having a cooling system that can obtain uniform cooling performance in the circumferential direction.
本発明は、従来の炉壁冷却性能すなわち冷却流量が周方
向に不均一になる原因が、冷却ナト、リウムの流路４１
面の一辺が非常に大きいためであることに着目して、流
路にスパージャを設置することにより均一な流量を確保
するものである。The present invention solves the problem that the cause of the conventional furnace wall cooling performance, that is, the cooling flow rate being non-uniform in the circumferential direction, is
Taking note of the fact that one side of the surface is very large, a sparger is installed in the flow path to ensure a uniform flow rate.
第２図に、不発明実施例の炉壁冷却パスを、又、第３図
にスパージャを示す。FIG. 2 shows the furnace wall cooling path of the non-inventive embodiment, and FIG. 3 shows the sparger.
第２図には、原子炉容器１と断熱構造９、冷却パス１０
、それにバイパス１１とスパージャエ２を示す。Figure 2 shows a reactor vessel 1, a heat insulating structure 9, and a cooling path 10.
, and also shows the bypass 11 and the sparge 2.
本実施例は、炉壁冷却バス１０の入口すなわち下部にス
パージャを設置した例であシ、スパージャに設けられた
多数の開口部からの噴流によシ、原子炉容器周方向の均
一冷却性能を得ようというものである。このスパージャ
の設置箇所は、第１図の高圧ブレナム６の出口すなわち
、炉壁冷却用バイパス１１の入口でも同様の効果が得ら
れる。This embodiment is an example in which a sparger is installed at the entrance, that is, at the bottom of the reactor wall cooling bath 10. Uniform cooling performance in the circumferential direction of the reactor vessel is achieved by the jet flow from a large number of openings provided in the sparger. It's about getting something. This sparger can be installed at the outlet of the high-pressure blemish 6 shown in FIG. 1, that is, at the inlet of the furnace wall cooling bypass 11, to achieve the same effect.
その場合の実施例を第４図に、第５図にスパージャを示
す。この時には、バイパス１１は管ではなく、炉壁冷却
バス１０と同様な構造つまり二重コーン構造となる。An example in that case is shown in FIG. 4, and a sparger is shown in FIG. At this time, the bypass 11 is not a pipe but has a structure similar to that of the furnace wall cooling bath 10, that is, a double cone structure.
以上本実施例によれば、原子炉容器壁の全周にわたる均
一流量が確保でき、均一冷却が可能である。As described above, according to this embodiment, a uniform flow rate can be ensured over the entire circumference of the reactor vessel wall, and uniform cooling is possible.
本発明によれば、原子炉容器壁の冷却において、周方向
の温度を均一にする効果がある。According to the present invention, in cooling the reactor vessel wall, there is an effect of making the temperature uniform in the circumferential direction.
