Abstract
The present invention provides instrumentation equipment for a nuclear power plant in which the formation of bubbles in an impulse line can be surely inhibited and thereby reliability and maintainability are improved for a long period of time. Instrumentation equipment for a nuclear power plant including: a tubular impulse line provided on a site to measure a fluid to be measured in a primary system of a nuclear power plant; a sealed liquid filled within the impulse line; a pressure-sensing diaphragm provided in a state of closing one opening of the impulse line to receive a pressure of the fluid to be measured; a pressure sensor provided on another opening of the impulse line in a state of being exposed to the sealed liquid; and a hydrogen storage material provided within the impulse line.
