Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current inspection methods for radioactive waste bodies require separate devices for surface contamination and dose rate inspections, which can lead to inaccuracies due to the concavo-convex shapes and shifts of the waste bodies during inspection, necessitating a unified solution that considers concavo-convex information for accurate dose rate measurements.
Innovation Solution
A radioactive waste body inspection device integrating a surface contamination inspecting unit and a dose rate inspecting unit, where the surface contamination inspection generates concavo-convex information used to maintain a constant dose rate inspection distance, ensuring accurate dose rate measurements even with concave or convex surfaces and shifts during rotation on an inspection table.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate devices are used for surface contamination inspection and dose rate inspection, then each inspection can be conducted independently, but measurement precision deteriorates due to concavo-convex shapes and shifts of the waste body
Solution Approach 1:
The patent combines the surface contamination inspection device and dose rate inspection device into a single integrated inspection system. The surface contamination inspecting unit and dose rate inspecting unit share common components including the inspection table, rotation mechanism, and detection systems. This merging allows both inspections to be performed simultaneously on the same waste body position, eliminating measurement errors caused by waste body shifts between separate inspections while maintaining independent inspection capabilities through software-controlled measurement modes.
2Adaptability or versatility
If the waste body is moved between separate inspection devices, then different inspection types can be performed, but inspection time increases and measurement accuracy decreases
Solution Approach 1:
The integrated inspection device enables continuous inspection operations by performing surface contamination and dose rate measurements in sequence without moving the waste body between devices. The waste body remains stationary on the rotation stage while the detection units sequentially measure different parameters. This continuous operation eliminates the time loss associated with transporting waste bodies between separate inspection facilities while maintaining the ability to perform both inspection types through coordinated measurement cycles.
3Productivity
If the waste body rotates on the inspection table, then all surfaces can be inspected, but maintaining constant detection distance becomes difficult due to concavo-convex surfaces
Solution Approach 1:
The inspection device incorporates feedback mechanisms where the detection units continuously monitor the distance to the waste body surface during rotation. When concavo-convex surfaces cause distance variations, the system uses this feedback information to adjust the detection geometry or apply correction factors to the measurements. This feedback control maintains measurement precision across all surfaces of the rotating waste body, enabling complete surface inspection while compensating for distance variations caused by surface irregularities.
