置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a crud separation device, and in particular, between a magnet for applying a magnetic field to the crud in the reactor coolant to separate the crud, and a reactor coolant flow path.
The present invention relates to a clad separation device in which a suitable relationship is established.
クラツド分離装置は、原子炉冷却材の管路途中
に設けられて、クラツド（Fe2O3、Fe3O4などの
酸化鉄微粒子）を分離除去するために使用され
る。 A crud separator is installed in the middle of a reactor coolant pipe and is used to separate and remove crud (fine iron oxide particles such as Fe 2 O 3 and Fe 3 O 4 ).

炉冷却材が使用されている。 In general nuclear reactors, fluids such as light water, sodium, carbon dioxide, helium gas, and reactor coolants are used depending on the type of reactor to extract the heat generated in the reactor core.

観測されている。これらのクラツドは微粒子であ
るために、通常の原子炉の運転には影響を及ぼさ
ないものと考えられている。 By the way, many constituent materials such as high-quality steel are used in nuclear reactor pressure vessels, piping, etc., and due to the effects of erosion caused by radioactive thermal energy during reactor operation, the above-mentioned crud is produced as radioactive corrosion products. It is said that a phenomenon occurs in which the particles are generated, mixed into the reactor coolant, and circulated through the pipes. These cruds are extremely small and depend on the operating history of the reactor and differences in the constituent materials, but the particle size is about 1 to 10 micrometers (μm) and gradually grows. It has been observed that there is a trend. Since these cruds are fine particles, they are thought to have no effect on normal nuclear reactor operation.

支障を来たす事ともなる。 However, since the crud is contained in the reactor coolant in a suspended state, the crud settles and accumulates in areas where the flow velocity is slow or during shutdown. These are radioactive products containing CO 60 and have a high radiation dose, significantly increasing the air dose. Therefore, it may cause radiation exposure, and adhesion to precision equipment of the nuclear reactor system may impede the operational functions and stability of the nuclear reactor.

The purpose of this is to guide the crud using an alternating magnetic field, focusing on the fact that the crud is a magnetic material, and to create stirring between the crud moving in the reaction chamber and the flow of reactor coolant.

It is characterized by providing a flow path guide for guiding the coolant, and widening the flow path near the end of the flow path guide to facilitate the collection of crud to slow down the flow of the reactor coolant.

がほとんど発生しないことになる。 As shown in FIG. 3, the flow of reactor coolant fed from the fluid inlet 7 of the reaction chamber 2 as shown by the arrow A is weakened by the existence of the buffer 27, etc. , C, the liquid is guided by the flow path guides 9A, 9B to reach the bottom of the reaction chamber 2, and then flows along the bottom in the direction of rotation of the magnet as shown by arrow D. At this time, the reactor coolant is transferred to the large reaction chamber 2.
Therefore, the flow changes to a gentler flow as it moves away from the flow path guides 9A, 9B. In addition, in order to prevent turbulence, a buffer 1 as shown in Figure 3 is used.
0A, 11A, and 12A are provided to have the effect of preventing the crud from flying up. Furthermore, the reactor coolant is bent by the flow path restriction guide 10 while rising little by little as shown by arrows E and F.
After the flow is further weakened, it is discharged from the fluid outlet 8 as shown by arrow T. Therefore, in most of the interior of the reaction chamber 2 except for the flow path guides 9A, 9B and the bottom, the flow is slow, and together with the buffling effect, there is almost no stirring of the reactor coolant.

れるものである。 In addition, both support frames 10 and 1 are driven by the drive mechanism 22.
1 is in a rotating state, an alternating magnetic field of, for example, 3 to 10 Hz acts on one point, and an attractive magnetic field due to a strong magnetic field between different poles opposes the fluid to form a traveling alternating magnetic field. Therefore, the cladding is moved in the direction of the arrow in FIG. 3 (toward the partition wall 4) by riding the advancing magnetic field along with the attraction, but the magnetic field formed by each magnet is affected by the viscous resistance of the reactor coolant. It is ultimately guided to the partition wall 4 while riding the advancing magnetic field that is formed one after another, slightly later than the movement of the magnetic field. Furthermore, during suction, the clads become interconnected due to the magnetization of the clads, making the particles larger (granulation effect), making their magnetic behavior easier.
It also helps the sedimentation due to its own weight,
The crud is collected along the partition wall 4 in the crud storage section 7. Below, clad storage section 7
The crud collected is taken out and processed as appropriate.

れるものである。 This sedimentation effect of the crud prevents the reactor coolant from being stirred in most of the reaction chamber 2.
The higher the concentration of crud, the easier it is for it to gradually grow larger due to magnetization, so this phenomenon can be noticeable in the lower part of reaction chamber 2. In addition, the flow of reactor coolant is as shown by arrow D in Figure 3. Due to the synergistic effect of the cladding and the movement of the cladding in the circumferential direction by the magnet, the cladding is ultimately deposited in the cladding storage section 11 located at the bottom of the reaction chamber 2 along the inclined flow path guide 9B. will be collected. Below, the clad storage section 11
The crud collected is taken out and processed as appropriate.

Separation and collection can be performed smoothly. Since the flow towards the crud storage section is caused near the bottom of the reaction chamber where the crud is concentrated and pulverized, the crud collection efficiency can be increased. .
