Abstract

PURPOSE:To judge the rate of leakage accurately, by providing a display device, which displays pressure value and temperature in a part to be inspected, and a recorder, which records the values, and adding a correcting value based on temperature change to the pressure value. CONSTITUTION:When the air leakage of a first cask 1 is inspected, each of plugs 12A-12E of a first pressurizing unit 7 is connected to a hole 21 between each valve box part 4 and a double O ring at a lid part. The valves of pressurizing bombs 14A-14D are opened, and a specified air pressure is applied to each part to be inspected. Then the valves of the pressurizing bombs 14A-14D are closed, a valve V-1 of a pressure detecting part is closed, and the apparatus is left intact for a specified time. When air leaks from the O ring, the pressure is gradually decreased. The leakage is detected by a first pressure detecting part 16, displayed on a display device 44, and recorded on a two-pen recorder 45. The temperature in a pressure detecting part is detected by a thermocouple, and the detected value is recorded and displayed on the display device.

For example, when spent nuclear fuel is forcibly transported using a spent nuclear fuel transport container (hereinafter referred to as a cask), if the cask is not airtight enough during transportation, a major accident may occur due to radiation leakage. Therefore, it is necessary to strictly inspect whether the cask is completely airtight before transportation. Conventional inspections are carried out by pressurizing and pressurizing the part to be inspected, leaving it for a certain period of time, reading the pressure drop in the part to be inspected with a U-shaped water manometer, and measuring the leakage rate. ing. However, since this pressurized leaving method uses the entire water manometer, it is sensitive to the external environment, especially humidity, and the larger the volume of the area to be detected, the more likely that even the slightest temperature change will have a negative impact on the manometer water level. There is. For this reason, it takes a long time to perform an airtight leakage test and stable measurements are possible, which is a major hindrance to transportation work.

Therefore, the present invention provides an air leakage inspection device for radioactive material transport containers, etc., which completely eliminates these problems.The first feature of the invention is that air is pressurized into a predetermined part to be inspected. A press fit is provided in a pressurizing unit that has an air supply section, a pressure detection section that detects the pressure inside the inspected section, and a temperature detection section that detects the humidity inside the inspected section, and based on the input signal from the pressure detection section. The reason for this is that a display device is provided to display the pressure value and the degree of pressure inside the part to be inspected, and a recorder to record the pressure. The influence of changes can be reduced, and since the temperature of the part to be inspected is detected at the same time as the pressure value is detected, the leak rate can be accurately determined by adding a correction value due to humidity changes to the pressure value. be.
