摘要： A system and method of injecting a chemical into a high pressure process stream without pumps or other active components. The system utilizes the differential pressure created by resistive losses of downstream components within a high pressure process stream. A bypass side stream is taken from an upstream pressure location and returned to the downstream side of the resistive inline process component. The chemical solution vessel is pressurized by the higher side of the pressure differential. The solution then passes through a flow controlling capillary tube exiting on the lower pressure differential side into the bypass stream. The high flow rate chemically diluted bypass stream then returns to the process stream at the lower differential process stream tie-in. The chemical solution is isolated from the process water pressuring the vessel by a movable separating device preventing mixing of the two fluids. The vessel can also be pressurized by gas.

摘要： A method for mitigating crack growth on the surface of stainless steel or other alloy components in a water-cooled nuclear reactor wherein a solution or suspension of a compound containing a noble metal is injected into the coolant water while the reactor is not generating nuclear heat, e.g., during shutdown or recirculation pump heatup. During shutdown, the reactor coolant water reaches temperatures as low as 120.degree. F., in contrast to the water temperature of 550.degree. F. during normal operation. During pump heatup, the water temperature reaches 400.degree.-450.degree. F. At these reduced temperatures, the rate of thermal decomposition of the injected noble metal compound is reduced. However, radiation-induced decomposition also occurs inside the reactor. In particular, the noble metal compound can be decomposed by the gamma radiation emanating from the nuclear fuel core of the reactor. The noble metal compound decomposes under reactor thermal and radiation conditions to release ions/atoms of the noble metal which incorporate in or deposit on the oxide film formed on the stainless steel and other alloy components. As a result, the electrochemical potential of the metal surface is maintained at a level below the critical potential in the presence of low levels of hydrogen to protect against intergranular stress corrosion cracking.
摘要翻译：一种用于减轻水冷核反应堆中不锈钢或其他合金组分表面上的裂纹扩展的方法，其中将含有贵金属的化合物的溶液或悬浮液注入冷却水中，同时反应器不产生核热，例如在停机或再循环泵加热期间。在停机期间，反应堆冷却水的温度低至120°F，与正常运行时的550°F水温相反。在泵加热期间，水温达到400°-450°F。在这些降低的温度下，注入的贵金属化合物的热分解速率降低。然而，辐射诱导的分解也发生在反应器内部。特别地，贵金属化合物可以通过从反应器的核燃料芯发出的γ射线分解。贵金属化合物在反应器热和辐射条件下分解，以释放掺入或沉积在不锈钢和其它合金组分上形成的氧化膜上的贵金属的离子/原子。因此，在低水平的氢气存在下，金属表面的电化学势能保持在低于临界电位的水平，以防止晶间应力腐蚀开裂。

摘要： A method for improving the performance and longevity of coatings of metal deposited from aqueous solutions of inorganic, organic or oraganometallic metal compounds. The method involves co-deposition of noble metal or corrosion-inhibiting non-noble metal during growth of oxide film on a component made of alloy, e.g., stainless steels and nickel-based alloys. The result is a metal-doped oxide film having a relatively longer life in the reactor operating environment. In particular, incorporation of palladium into the film provides greatly increased catalytic life as compared to palladium coatings which lie on the oxide surface.

摘要： A system for ensuring the distribution of noble metal in the reactor circuit during plant application without measuring the reactor water for noble metal content by chemical analysis. The system performs the measurement of electrochemical corrosion potential in an autoclave or a high-flow test section that is connected to the reactor water circuit through sample lines downstream of the injection port, preferably the point in the reactor circuit which is furthest from the injection port. If the noble metal flows into the autoclave or test section at these distant points in the reactor circuit, then the noble metal will deposit on the test specimens inside the autoclave or test section. After the noble metal has been injected for a predetermined duration, the electrochemical corrosion potential autoclave or test section is exposed to hydrogen water chemistry conditions and the electrochemical corrosion potentials of the specimens inside the autoclave or test section will be measured to determine the extent of their catalytic response. A good catalytic response indicates that the noble metal has reached the locations upstream where electrochemical corrosion potential is being measured.
