摘要： Both ends of a circulation pipe of a film formation apparatus are connected to a piping of a BWR plant. A chemical including chromium ions and formic acid is injected into a film formation solution flowing in the circulation pipe heated to a temperature within a range from 60° C. to 100° C. Furthermore, a chemical including iron (II) ions and formic acid, hydrogen peroxide, and hydrazine are injected into the circulation pipe. Due to the injection of these chemicals, a film formation solution of pH 7.0 including iron (II) ions, chromium ions, formic acid, hydrogen peroxide, and hydrazine is generated in the circulation pipe. This film formation solution includes hydrazine of, for example, 1000 ppm. The film formation solution is supplied to the piping, thus, a Fe3—xCrxO4 film (here, 0

摘要： A nuclear reactor structural material (for example, a spacer spring) is immersed in purified water in a treatment bath. The temperature of the purified water increased to 90° C. by a heater. Iron formate (a solution containing iron (II) ions) in an iron formate tank, hydrogen peroxide in a hydrogen peroxide tank, and hydrazine in a hydrazine tank are injected into a pipe and are guided into the treatment bath. The injection of iron formate is performed until the concentration of iron (II) ions in the purified water becomes 200 ppm or more. By injecting hydrazine, pH is adjusted in a range of from 5.5 to 9.0. A portion of a magnetite film thus formed on the structural material is then removed, e.g., by applying ultrasonic waves. With this process, a fine strong magnetite film for suppressing the elution of cobalt from the nuclear reactor structural material is formed on the surface of the nuclear reactor structural material.

摘要： A natural circulation boiling water reactor provides to a chimney with a plurality of tubes. That is to say, each of the plurality of tubes partitions the coolant flow path above a core. Thus, unlike the conventional natural circulation boiling water reactor providing the flow path partition wall grid in which the plate members are made integral by welding and coolant flow paths are partitioned, the chimney of the natural circulation boiling water reactor can reduce the number of welded portions because the edges of the four corners of each flow path do not need to be welded. The natural circulation boiling water reactor can avoid removal as a single unit, as in the case of the flow path partition wall grid in the conventional natural circulation boiling water reactor, by detaching each tube. The chimney can be easily detached from the reactor pressure vessel.
摘要翻译：自然循环沸水反应器提供给具有多个管的烟囱。也就是说，多个管中的每一个将冷却剂流动路径分隔在核心上方。因此，与传统的自然循环沸水反应器不同，通过焊接使板构件成为一体的流路分隔壁网格，并且冷却剂流动路径被分隔，自然循环沸水反应器的烟囱可以减少焊接部分的数量因为每个流路的四个角的边缘不需要焊接。自然循环沸水反应堆可以避免作为单一单元的去除，如在传统的自然循环沸水反应器中的流路分隔壁网格的情况下，通过分离每个管。烟囱可以容易地与反应堆压力容器分离。

摘要： It is an object of the present invention to efficiently suppress radionuclide deposition on a reactor component of nuclear power plant. Radionuclide deposition on the surface of a metallic reactor component of nuclear power plant is suppressed by forming a ferrite film on the component, wherein the film is formed, after decontamination for removing radionuclides contaminants from the component surface is completed and before the plant is started up, by contacting a treatment solution which mixes a first agent containing the iron (II) ions, a second agent for oxidizing the iron (II) ions into the iron (III) ions and a third agent for adjusting pH level of a solution to 5.5 to 9.0 in this order with the reactor component surface.
