摘要： In a radiation measurement apparatus, an analog pulse signal output from a semiconductor radiation detector is converted to a plurality of digital signals by an analog-to-digital converter for each analog pulse signal. A threshold circuit for inputting these digital signals discriminates digital signals exceeding a threshold value. A digital signal integration circuit integrates the plurality of discriminated digital signals for each analog pulse signal and obtains an integrated value for each analog pulse signal. A spectrum generation circuit for inputting the respective integrated values generates a radiation energy spectrum using the integrated values and accurately performs the quantitative analysis and energy analysis of a radioactive nuclide using the radiation energy spectrum. A quantitative analysis and an energy analysis of a radioactive nuclide can be accurately performed while a time resolution of a radiation detector can be maintained.

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 water chemistry factor which is specific to a specific portion of a primary cooling system and universal is decided to be a standard target. The concentration of an agent for mitigating corrosion damage of structural material of the primary cooling system is controlled so that the target will be in a desirable range. All sensor groups provided in the primary cooling system are separated into sensor groups in different lines, of which a specific sensor group are connected to an arithmetic unit and a data base and are for always monitoring a plant process. For example, concentration distribution agreed with measured value oxidation component in the reactor water at the measurement points is selected from the data base, and it is used to estimate the standard target.
