MEASUREMENT METHOD FOR NUCLEAR REACTOR STRUCTURE

摘要

PURPOSE: The measuring method of the Atomic Electrical Power Plant hanger structure minimizes the interference problem with the inside instrument of the hanger structure and structure. The exact measured value of the Atomic Electrical Power Plant hanger structure is gotten. CONSTITUTION: The cylindrical body(100) is that the receiving space is formed in inside. The domed ceiling portion(200) is formed on the top of the main body. The opening is formed to be penetrated in the main body. The measurement target is instituted among the inner surface of the ceiling portion as the target(210). A plurality of laser distance sensors is installed in order to face target. The pressurized about the inter space of the main body and pressure reduction are enforced through opening.
