Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current monitoring systems for nuclear facilities are inadequate in detecting and predicting radioactive contamination in groundwater, particularly in real-time, and fail to provide comprehensive, three-dimensional diagnostics of contaminant plumes, which poses risks to human health and increases the costs and duration of nuclear power plant decommissioning.
Innovation Solution
An integrated monitoring system that includes a field monitoring system with a multiple packer system to isolate and measure groundwater characteristics at various depths, using an automatic branching apparatus to collect and analyze data, which is then transmitted to a remote monitoring apparatus for real-time analysis and 3D graphic representation of contaminant plumes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional monitoring systems are used, then system simplicity is maintained, but real-time detection and 3D diagnostic capability are insufficient
Solution Approach 1:
The monitoring system is divided into multiple independent components: field monitoring systems at different depths, automatic branching apparatus, data transmission modules, and remote monitoring apparatus. Each component performs a specific function, enabling real-time detection while maintaining modular complexity management.
Solution Approach 2:
The system transitions from conventional 2D monitoring to 3D diagnostic capability by incorporating vertical depth segmentation with multiple packers at different levels, horizontal distribution monitoring through branching apparatus, and temporal real-time data collection, creating a three-dimensional monitoring space for comprehensive contaminant plume analysis.
2Measurement precision
If comprehensive groundwater monitoring at multiple depths is implemented, then measurement accuracy is improved, but device complexity increases
Solution Approach 1:
The groundwater monitoring well is segmented into multiple isolated sections using packers at different depths. Each section can be independently monitored, allowing precise measurement of groundwater characteristics at specific depth intervals while managing system complexity through modular section-based control.
Solution Approach 2:
The automatic branching apparatus serves multiple functions: it connects to multiple groundwater flow pipes from different depth sections, enables selective sampling from any section, facilitates data collection from all depths, and provides a unified interface for remote monitoring, thereby reducing overall system complexity despite comprehensive monitoring requirements.
3Loss of time
If real-time data transmission and analysis is implemented, then response time is reduced, but energy consumption and system complexity increase
Solution Approach 1:
The system implements periodic data transmission and analysis cycles rather than continuous real-time transmission. Field monitoring systems collect data locally and transmit to remote monitoring apparatus at predetermined intervals, reducing energy consumption while maintaining timely contaminant detection capability.
Solution Approach 2:
Data transmission modules serve as intermediaries between field monitoring systems and remote monitoring apparatus, buffering and managing data flow to optimize transmission timing and reduce energy requirements while maintaining real-time detection capability.
