[0003] Although the diverter plate is constantly subjected to a high heat flux of 10 MW/m2 or more and its temperature rises, it is required that the surface temperature of the protective tile be suppressed to about 1000°C or less. Therefore, it is necessary to maintain a good bonding state of the brazed portion between the carbon material protective tile and the copper cooling pipe, or between the carbon material protective tile and the copper block, so as to sufficiently reduce the thermal resistance of the bonded portion. Conventionally, the method of inspecting this bonding state during manufacturing and/or during service is
Destructive inspection methods ■ Inspection methods using ultrasonic flaw detection and other methods have been studied.

First, in the destructive testing method, (1) It is actually impossible to completely destroy the diverter plate itself after it has been completed as a product to inspect the joint state. ■

Furthermore, in the ultrasonic flaw detection method, (1) Carbon materials have large attenuation of ultrasonic waves, resulting in very poor detection sensitivity. ■ Carbon materials (carbon composites) are non-homogeneous and porous materials, which causes diffuse reflection of ultrasonic waves, making detection difficult. ■To perform inspections during service, the procedure is extremely complicated, as a detector must be brought into the reactor, which is a radiation field, by remote control and measured by touching the surface of the divertor plate.

The above object is achieved by a method for non-destructive testing of a diverter plate as set forth in the claims. That is, a diverter plate installed in a nuclear fusion reactor that has a structure in which a protective tile made of carbon-based material and a copper cooling pipe is penetrated and bonded to the protective tile, or a protective tile made of carbon-based material and a cooling block made of copper. In the diverter plate having a structure in which the protective tiles are joined together, the protective tiles are heated from the side of the cooling pipe or the cooling block, the rate of temperature rise of each heated protected tile is measured using a radiation thermometer, etc., and the joining process is performed based on the measurement results. This is a non-destructive testing method for divertor plates that inspects the joint state of parts.

[Embodiment] The diverter plate is used when a copper cooling pipe (hereinafter referred to as a copper pipe) 32 is inserted into the protective tile 31 shown in FIG. 4 and joined by brazing, or when the protective tile 3
1 and a copper block (hereinafter referred to as the copper block) 33, a protective tile 31 made of carbon-based material having a surface area of about 30 mm square and a thickness of about 10 mm is installed inside the furnace. By brazing the back side of the protective tile 31 with the copper pipe 32 or copper block 33 and letting cooling water pass through the copper pipe 32 or the copper block 33, the surface temperature of the protective tile 31 can be raised to 1000°C. It is kept below.

[0011] The protective tile 31 and the copper tube 32 or the copper block 33 are usually bonded by vacuum brazing, but in rare cases, complete bonding may not be achieved. Furthermore, during the operation of a nuclear fusion reactor, there is a possibility that the joint between the protective tile made of carbon material and the cooling part 31 made of copper may peel off due to the difference in thermal expansion between them due to repeated thermal cycles.

When the fusion reactor is in service, the stop valve 7 and the stop valve 8 shown in FIG. 1 are opened, and the stop valve 9 and the stop valve 10 are closed to form a cooling system for the diverter plate 1. In other words, the low-temperature cooling water discharged from the circulation pump 5 flows into the divertor plate 1, cools the divertor plate whose temperature has increased due to the high heat flux from the plasma side, and raises its own temperature, causing the cooling water to flow into the divertor plate 1. Enter within 6. The cooling water, whose temperature has been lowered by heat exchange with another medium in the cooler 6, is again pressurized by the circulation pump 5 and sent to the diverter plate 1.

On the other hand, while a nuclear fusion reactor is in service, it is necessary to maintain a high degree of vacuum inside the reactor. Therefore, when installing the diverter plate 1, the diverter plate 1 is heated to about 200 to 300°C using high-temperature gas or hot water to purge the gas remaining on the surface. The baking system 3 is configured by closing the valve 8 and opening the stop valves 9 and 10, and the cooling water in the loop is circulated while being heated by the heater 4, thereby increasing the temperature of the diverter plate 1.
It has been considered to heat the gas and purge the above gas, etc.

When inspecting the joints of the diverter plate 1 according to the present invention, the cooling system for the diverter plate 1 is first switched to the baking system 3 described above. Next, the circulation pump 5 is driven to circulate the cooling water within the system, while the heater 4 is operated to raise the temperature of the circulating cooling water. Accordingly, heat is transferred from the cooling member side to the protective tile 31 side of the diverter plate 1, and the temperature of the furnace inner surface of the protective tile 31 increases.

At the same time, a thermometer 2 such as a radiation type is installed inside the furnace.
The diverter plate 1 is held and disposed so as to be movable and swingable by a robot or the like so that the surface temperature of all the diverter plates 1 can be measured.

[0017] When the protective tile 31 and the cooling member are sufficiently bonded, the surface temperature of the protective tile 31 increases almost uniformly, but some parts of the bonded portion are peeled off. In this case, heat transfer in that area is inhibited, and the rate of increase in the surface temperature of the protective tile 31 is reduced. However, even in that case, by continuing heating from the cooling member side for a long time, the surface temperature of all the protective tiles 31 will eventually become approximately uniform.

Therefore, in the present invention, the rate of increase in surface temperature of the protective tile 31 at the initial stage of heating, which causes a difference in rate of temperature increase depending on the condition of the bonding members described above, is detected, and the rate of increase in temperature is measured in advance before inspection. The state of the joint is determined by comparing the previously prepared joint state with the data on the rate of temperature rise, and whether the protective tile 31 is sufficiently sound or within an acceptable range where some peeling is observed but is still sufficiently safe.

Alternatively, it determines whether immediate replacement is required.

In the case of a structure in which the protective tile 31 is divided into small blocks as described above, the soundness of the diverter plate 1 can be confirmed with sufficient accuracy by identifying the defective protective tile 31 according to the method prescribed in the regulations.

When heating the diverter plate 1, high-temperature gas or electrical heating may be used in addition to the above-mentioned heating by the baking system, and the protective tile 31 whose temperature has been raised by heating from the cooling member side may be used. Of course, a contact measuring device such as a thermocouple can be used to measure the surface temperature.
