Abstract
PURPOSE: To detect accurately a water level even during an accident of a boiling water or pressurized water reactor, by preventing the water from boiling by suppressing the quantity of external heat flowing into reference water head water and lower piping by providing insulating materials to a reference water head pipe, lower piping, etc., forming a water gauge.
CONSTITUTION: From the upper flank of nuclear reactor pressure container 1, upper piping 3 is extended into dry well 15 and to the lower part of reference water tank 4, reference water head pipe 5 stored with reference water head water is connected. On the other hand, piping 11 connecting with pressure measurement point 12 nearly in the center of container 1 is connected to lower piping 9 and the water level indication is composed of differential pressure converter 8, etc., outside of storage container 2. Those pipes 5, etc., and 11, 9, etc., are provided with insulating materials 13 and 14, such as asbestos, and even if the temperature of well 15 rises owing to the breaking of nuclear reactor piping, etc., the quantity of heat flowing into the reference water head water, pipes 11 and 9, etc., from the ambient atmosphere is suppressed to prevent the water from boiling. Therefore, the water level can be detected accurately even during the occurrence of an accident.
