摘要： A method for mitigating crack growth on the surface of stainless steel or other metal components in a water-cooled nuclear reactor. A compound containing a noble metal, e.g., palladium, is injected into the water of the reactor in the form of a solution or suspension. This compound has the property that it decomposes under reactor thermal conditions to release ions/atoms of the noble metal which incorporate in or deposit on the interior surfaces of the crack. The compound may be organic, organometallic (e.g., palladium acetylacetonate) or inorganic in nature. The palladium deposited inside a crack should exhibit catalytic behavior even if the bulk surface palladium is depleted under high fluid flow conditions. As a result, the electrochemical potential inside the crack is decreased to a level below the critical potential to protect against intergranular stress corrosion cracking.

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 along with a reducing agent. The presence of the reducing agent will assist in better deposition of the noble metal, for example, palladium, on metal surfaces, thereby increasing the noble metal loading and also improving the tenacity with which the noble metal is bound onto the metal. The extent of noble metal doping is important in providing a better (lower) ECP response of the metal in the presence of a stoichiometric ratio of H.sub.2 to O.sub.2, which reduces the hydrogen demand considerably. The more tenacious the noble metal is bound to the metal surface, the longer its expected life will be, particularly under in-reactor Situations where the metal surfaces are subjected to a variety of hydrodynamic conditions.

摘要： A resistance welding method for a fuel rod is presented in which the gas seal opening is closed with a sealing material of the same composition as the end plug material. The method enable to perform welding stably in a pressurized welding chamber, and the process is amenable to automation. The sealing material body is made of a wire, and is pressed against the conical shaped opening provided on the end plug. The welding method avoids contaminating the weld with undesirable impurities from the electrode material, and the welding operations is designed so that there is no need to reshape the end of the electrode or adjust the gap between the sealing material and the seal opening.

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.

摘要： In a field of commercial nuclear reactors, a control blade, which is inserted into and withdrawn from the core of a nuclear reactor so as to start/shut-down the operation thereof and to control the reactor power, must have soundness, high reactivity and long life. The control blade for nuclear reactors is arranged to prevent swelling of a neutron absorber so as to improve the soundness. Furthermore, even if the swelling takes place, the soundness of the control blade can be maintained. The control blade is arranged to prevent the swelling phenomenon in such a manner that boron exhibiting excellent neutron absorbing performance absorbs hydrogen which is produced as a result of reactions with the neutrons. The control blade for nuclear reactors has an upper structure member, a lower structure member, a central tie member disposed between the upper and lower structure members, a plurality of wings connected to each other by the central tie member, and neutron absorber enclosed in the wing. Each of the wings is constituted by a plate member made of hafnium metal, a hafnium alloy or an alloy the main component of which is zirconium or titanium. The neutron absorber comprises a long-lived type neutron absorber which is enclosed in accommodating holes formed in the front insertion portion of the wing which is exposed to a large amount of neutrons and a neutron absorber which is inserted into at least the major portion of the residual accommodating holes and which contains boron. A mixture of a material containing boron and a hydrogen absorber is enclosed in the accommodating holes for accommodating the neutron absorber containing boron disposed in a range from the front insertion portion, which is exposed to a large amount of neutrons, to 1/4 of the height L of an effective core portion of a nuclear reactor.
