摘要:
In a nuclear power plant, by injecting an amount of hydrogen small enough not to increase a radiation dose rate of the main steam system, ECP of metallic component materials composing a nuclear reactor can be decreased to suppress the potential of occurrence of IGSCC, and the control can be easily performed, and the operating cost can be suppressed to increase. Occurrence of intergranular stress corrosion cracking in metallic component materials in contact with reactor cooling water is suppressed by injecting zirconium hydroxide and hydrogen into the reactor cooling water to decrease the electrochemical corrosion potential of the metallic component materials.
摘要:
Surfaces of the structural components of a nuclear power plant exposed to reactor water are wetted with an electroless plating solution containing an electrical insulating substance. The electrical insulating substance has a high resistivity about 105 (100000) times those of the structural components of the nuclear power plant or above. A metal film containing the electrical insulating substance is formed on the surfaces of the structural components exposed to the reactor water by wetting the surfaces of the structural components with the electroless plating solution. Thus, the electrochemical corrosion potential of the structural components is reduced regardless of whether hydrogen is injected into the reactor water.

A light-emitting device combining a first luminous flux control member having a total reflection surface and emitting light from an emission surface in a narrow angle range centered mainly on an optical axis, and a second luminous flux control member arranged to surround the total reflection surface of the first luminous flux control member. The second luminous flux control member (102) of the light-emitting device is provided with a second incidence surface (126a) and a second emitting surface (126b). Of the light emitted from the light-emitting element (200), the light incident to the second incidence surface (126a) is within a range of angles θ larger than a largest angle to the optical axis of the light incident to the first luminous flux control member (101). The second emitting surface (126b) controls the light incident to the second incidence surface (126a) to have light distribution characteristics different from those of the light emitted from the first luminous flux control member (101), and emits the light.
