APPARATUS FOR OBSERVING STATE IN HIGH-PRESSURE VESSEL, ITS OBSERVATION METHOD, HIGH-PRESSURE SOLID REACTOR, HIGH-PRESSURE VESSEL INSPECTION APPARATUS, ITS INSPECTION METHOD, AND HIGH-PRESSURE REACTOR

摘要

PPROBLEM TO BE SOLVED: To speedily measure a concentration distribution of solids and the state of reaction in reaction containers from the outside of the high-temperature and high-pressure reaction containers. PSOLUTION: This apparatus for observing the state in the high-pressure containers comprises radiation sources 4a and 4b for irradiating radiation 10 to a high-pressure container 2 containing solid particles 3 for making the solid particles 3 react in a high-temperature and high-pressure state; radiation detectors 5a and 5b for detecting radiation 11 irradiated from radiation sources 4a and 4b and transmitted through the high-pressure container 2; and a data processing part 6 for computing a concentration distribution of the solid particles 3 in the high-pressure container 2 on the basis of output of the radiation detectors 5a and 5b. The data processing part 6 computes the concentration distribution on the basis of the difference with output of the radiation detectors 5 in the case of the absence of the solid particles 3 in the high-pressure container 2 with reference to the output of the radiation detectors 5.
