Description

TECHNICAL FIELD

[0001] The utility model relates to nuclear safety maintenance technical field especially, relate to the isolation shielding device. BACKGROUND

[0002] The radiation monitoring probe of nuclear power plant is the important equipment for monitoring the release of radioactive material and environmental radiation level. These probes are crucial for ensuring the safe operation of nuclear power plants, as they can monitor radiation levels in real time that can harm human health and the environment. If the radiation monitoring probe of nuclear power plant is blocked by adhesive tape, other objects, and the sensitivity is reduced.

[0003] During civil construction or equipment welding, component polishing, dust and smoke may be generated, which may trigger false alarms of radiation detectors or fire detectors (such as smoke detectors, heat detectors, etc.), so it is necessary to temporarily shield the detectors to avoid false alarms caused by dust or smoke. Currently, field workers temporarily shield the detectors by sealing the system sampling pipeline port of the radiation monitoring system with adhesive tape.

[0004] This method requires that appropriate preventive measures be taken to ensure the reliability of the detector before shielding to avoid damage to the detector or false alarms. In addition, in any case, shielding the detector is a temporary measure, and the shielding should be removed immediately after the problem is solved to ensure the integrity and functionality of the monitoring system. However, even if the field workers compile a list of detectors that are prohibited from being blocked by sealing the system sampling pipeline port of the radiation monitoring system and add a warning sign, there is still a risk that the adhesive tape will not be removed in time after being used to seal it, ultimately resulting in the loss of radioactive iodine monitoring in areas such as reactor buildings and nuclear auxiliary buildings, which cannot be detected in time and effectively if there is radioactive iodine, and there is a risk of diffusion.
