It has a neutron "small cross-section" as a sheath for the nuclear reactor. However, the age-old gold still has the insurmountable shortcoming, that is, it is easy to absorb hydrogen, and the wrong alloy-excessive mosquito-like sputum deposits, the gasification of the precipitated material has a serious mechanical property to the bismuth alloy. influences. In view of this, the American Electric Power Research Institute (EPRI) is jointly researching this problem with the international industry and academia. The Nuclear Energy Research Institute is the main research unit. The project is divided into two phases: ^ib segment focuses on the concentration of money, and the need for a combination of gold and gold. The second stage of financial considerations is the actual condition of the mysterious sheath. Fuel rod sheath i is a fuel-pile ship water (cold county), and the outer layer of the fuel rod sheath is cooled (10), which also makes the hydrogenation age of the fuel rod sheath into an outer shaft. This is the first stage study. The distribution of the average sentence = significant difference, the need for uneven hydrogenation of the alloy. The present invention is directed to the second stage, which is proposed for obtaining a faulty alloy test piece of uneven hydrogenation. The wrong alloy hydrogenation method is mainly gas charging method and hydrogen charging method. When the first-stage research project was carried out in this laboratory, the nitrogen-filled alloys were widely used. The current hydrogen-charged appliances were all below 2 GGppm. This laboratory is active for nine gas squares/i: l?ij has low-pressure heat. The invention of the cyclic hydrogen charging method is being applied for in another patent. The first research and demand is the wrong alloy test piece with uneven distribution of sputum sputum, 1262955 is research and development, and Junsaki is not arrogant, and has the invention of this technology for the purpose of planning. SUMMARY OF THE INVENTION In a preferred embodiment of the invention, the method comprises: controlling a high heat flux plus 'to control the amount of migration of gas atoms' and slowly reducing the high heat flux rate. The main object of the present invention is to provide a controlled hydrogenation miscution The re-distribution of the material. The uniform 11-factor alloy tube 'drives the wrong alloy tube atom with high heat flux heating method to control the redistribution of the hydrogenation mis-precipitate of the niobium alloy tube. & The present invention (IV) - a main object is to provide a controlled hydrogenation domain separation portion which mainly includes a wire arrangement and a high pressure water circuit device. Its towel, heating = used to heat the wrong alloy tube. In the preferred embodiment of the present invention, the heating device can be a high-power electric heating rod, and the wrong alloy casing is heated by the inner wall of the gold casing of the same age. #然, this scaleing ^ includes a power controller to provide the electrical power required for a high-power electric heating rod. °匕 As for the partial pressure water loop device, it also includes boiling water fuel tank, heat exchange water tank, high pressure pump, back pressure regulator, pressure gauge, voltage regulator and flow measurement. Among them, the boiling water fuel tank can just be placed in the wrong alloy casing to control and cool the zirconium alloy casing. The hot wire is set to (4) sufficient _ heat energy, Lai lead boiling water = high pressure cold water of the tank and high pressure hot water for cooling and boiling water tank. The sink is used to supply the source. The high pressure pump is used to push the water source in the water tank to the boiling water fuel tank. Back; = 1262955 Water tank for tanks. The pressure measurement meter uses the "K water source, 4 water fuel tank _ to be exported to the pressure of the high dust water of the tank. In order to know the water and dust of the boiling water fuel tank, the road device is further included. The water pulse of the loop is measured in the 'high water ring τ', and the distribution of the precipitated hydride is determined by setting a flow rate of secret water to the water tank. The method and the method of installing the L11 heat flux rate effectively drive the hydrogen atom on the alloy, _effect = demand. [Embodiment] In order to enable the reviewing committee to understand and understand the characteristics of the present invention, the detailed description of the drawing is as follows. : % has a more advanced step-by-step alloy 4 (four), because the residual gold correction 纽 虱 纽 合金 合金 合金 合金 有 有 has a more obvious movement rate. On the other hand, the temperature is more redistributed, it is necessary to be higher At the temperature, there is a significant 3 knives weathering = f to explore the hydrogen secret alloy ____, its drive _ (Driving degree difference, Zhao and stress difference, as reported by the literature, the effect of the stress difference = two as before The higher the temperature, the higher the solubility of hydrogen, because of the temperature The difference is also i 'so, how to make a large temperature difference between the inner and outer walls of the gold wire should be the gas atomic drive mode, that is, the most effective new alloy such as the record 1262955. First, the process of hydrogenation of the touch distribution is first processed. As a step. Then, _ high heat flux rate of heat, the phenomenon of uniform hydrogenation is the result of the smashing of the stagnation of the ageing, and the distribution of hydrogen atoms is controlled by the age of gold. The hydrogenation mis-precipitation distribution is controlled, which is step 102 in order to provide the research, that is, to simulate the actual condition of the fuel rod sheath, that is, the hot external cooling in the rod county and the precipitation of the Chandler is slow. The invention specially applies high heat flux (HeatFlux) heating to the inner wall of the casing of the wrong alloy sample, and the high-alloy water-cooling method of the outer wall of the wrong alloy test piece enables the wrong alloy to form the wrong alloy sleeve under appropriate high temperature conditions. In the cold outside the tube, the red Wei, the retracement slow down the temperature of the implementation, the layered gradient distribution of the hydrogenation error is precipitated, this is the step 1 〇 3. So - to 'real simulation _ rod sheath operation _ actual situation, Make The hydrolyzed precipitates of the dream alloy tube exhibit a layered gradient distribution (Gradien1istributi〇n) for the purpose of research. In the present invention, the invention combines two power electric heating rods and a small high-pressure water loop with so-called boiling water. The fuel tank (Boiling Capsule) operates in such a way that the bismuth alloy tube to be treated is subjected to a high heat flux rate at the same temperature as the boiling point of the normal pressure water (1 〇〇. ,, resulting in a significant temperature difference between the inner and outer walls of the bismuth alloy sleeve, driving hydrogen The atom moves to the outer wall with a lower temperature to achieve the desired external distribution of the hydrogenated ruthenium. Please refer to Figure 2, which is a schematic diagram of the apparatus for controlling the redistribution of bismuth telluride in the present invention. The controlled zirconia precipitation redistribution device 2 〇〇 mainly includes a heating device 210 and a high pressure water circuit device 220. In the preferred embodiment of the present invention, the heating device 210 is mainly a high-power electric heating rod, which can be placed in the sleeve of the zirconium alloy sample 230. When the heating device 21 is controlled by a power of 215 pairs of electric heating rods When the two poles supply voltage, the electric heating rod can heat the inner wall of the 23 〇 sleeve 1262955 of the wrong alloy sample. The high-pressure water circuit is equipped with a heat exchange device 245, a water sample 250, and a Gushui heart to include a Buddha water fuel tank 240 and a meter 265.曰 L L 浦 255, back pressure regulator 260, pressure amount on the 再 鍅 再 再 装 装 推 HL HL 官 官 官 官 官 官 官 官 官 官 官 官 官 官 官 官 官 官 官 官 官 官 HL HL 水槽 水槽 水槽 水槽 水槽 255 255 255 255 Set 24 = energy, and drop (four) water burning high pressure water _ ^ _1 ton 1 gin gold away from the outer wall of 23G wire, the surface of the outer wall of the Buddha ... tens μ degrees depending on the water pressure of pure cooling water, and then flow to the water ^Water will be combined with the heat of the 23 〇 casing outer wall of the gold sample to allow the outer and inner walls of the two sets of the wrong alloy to form external cold internal heat. "7, water fuel tank 240 high pressure water return county f pressure adjustment m = 50. As for the pressure measurement meter 265, it is the fine-pressure water of the detective tank. Therefore, the amount of cooling money that is made by secret-controlling the silk can be transferred to the outer wall at a suitable high temperature when the inner wall of the dam is heated. ,,,,, when using a simulated bismuth alloy sheath. ... ^ In order to more accurately control the water pressure of the high pressure water, the high pressure water circuit device 22 is shown in the preferred embodiment, in particular, a voltage regulator 270 is provided on the path of the high pressure pump to push the high pressure water to the toe. The pressure of the high-pressure water can be stabilized and the high-pressure water is led to the path of the water tank 250. The flow measurement is additionally provided. The wrong alloy has good thermal conductivity, and it is necessary to make a significant temperature difference in the wall thickness of the wrong alloy test piece only about 〇 75_, and only a high heat flux heating method can be achieved. Therefore, it is better to set the W/m high-dissolving rod of the 2-piece dish, and the special 1262955 is smaller than the inner diameter of the niobium alloy sheath to be placed in the sheath, and then the wrong alloy sheath It is locked in a specially designed double-layer boiling water fuel tank 240 by means of a lock.

Therefore, the present invention reuses the power analyzer and the program control component-set power control (10) system, accurate Controlling the output of power and the rate of power rise and fall of the heating device 210. Under the above conditions, the distribution of the mis-synthesis of the wrong alloy tube of the present invention, please refer to the hydrogenation in Figure 5A~Figure 5〇[5A~5c) Mistakes show different degrees of intimacy, and Figure 4 is really wrong. Compared with the distribution of hydrogenated ruthenium on the gold sheath, it is quite similar. Therefore, the invention can completely control the operation mode of the actual rod sheath, and at the same time, the high pressure loop can be adjusted according to the demand, thereby controlling the temperature of the outer wall of the alloy f, and then Through the power control of the heating device and the length of the process, the fuel rod sheath hydrogenation fault distribution of different conditions is developed to meet the research requirements. 1262955 "In view of the above, the present invention proposes a method for controlling hydrogenated cerium precipitates.
