<P>PROBLEM TO BE SOLVED: To provide a water level and temperature measurement facility for a nuclear reactor containment vessel, capable of measuring presence or a fluid level (water level) of coolant and temperature in a reactor containment vessel even when the coolant such as water or sea water builds up in the reactor containment vessel due to a severe accident of a nuclear power plant. <P>SOLUTION: A water level and temperature measurement facility for a nuclear reactor containment vessel includes a nuclear reactor containment vessel 3 which accommodates a reactor pressure vessel 2, and a plurality of temperature gauges 4 deployed inside the reactor containment vessel 3 along the height direction thereof to measure temperatures inside the reactor containment vessel 3. While temperature inside the reactor containment vessel 3 is being detected by each of the temperature gauges, a temperature value detected by each temperature gauge 4 is compared with a temperature value that should be detected when the temperature gauge is submerged in coolant such as water to check for presence of coolant inside the reactor containment vessel 3. <P>COPYRIGHT: (C)2013,JPO&INPIT |
