Solution Overview

Problem

Current methods for disposing of nuclear waste are inadequate, with no acceptable 'permanent' solution available, and existing containers are vulnerable to leakage, theft, and sabotage, posing environmental and health risks.

Innovation Solution

A detection and containment system featuring a first containment layer, a sensor layer with a signal path, and a second containment layer, which detects breaches by monitoring the continuity of a signal path and triggers alarms for any disruption, providing real-time monitoring and immediate alerts for potential leaks or intrusions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional containers are used for nuclear waste storage, then the storage capacity is sufficient, but the containers are vulnerable to leakage, theft, and sabotage

Engineering Contradiction:
Improvecontainer securityVSAvoidcontainer structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements a multi-layer containment structure where an inner liner is nested within the main container body, and a sensor layer is integrated between the liner and the outer shell. This nested arrangement allows each layer to provide specific functions (containment, sensing, structural support) while maintaining overall system compactness and security without excessive complexity

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The sensor layer is pre-integrated into the container structure during manufacturing, positioned between the inner liner and outer shell. This preliminary integration ensures that detection capabilities are built-in from the start, allowing immediate detection of breaches, corrosion, or tampering events without requiring additional external monitoring equipment

Inventive Principle:
Principle #10Preliminary action

2Measurement precision

If continuous monitoring is implemented to detect breaches, then detection capability is improved, but system complexity increases

Engineering Contradiction:
Improvebreach detection capabilityVSAvoidmonitoring system
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines multiple detection functions (breach detection, corrosion detection, tampering detection) into a single integrated sensor layer that is embedded within the container structure. This merging of functions into one unified system provides comprehensive monitoring capability while avoiding the complexity of multiple separate detection systems

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The sensor layer serves multiple purposes simultaneously: it detects physical breaches through discontinuity sensing, monitors corrosion through electrical resistance changes, and identifies tampering attempts. This multi-functional design achieves high measurement precision for various threat types without proportionally increasing system complexity

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A system for detecting and containing a breach in a container. The container wall includes containment layers and a sensor layer sandwiched between the containment layers. The sensor layer contains a signal path that can be carried by a signal cable such as fiber optic or wire cable. The containment layers contain shards of material. When the wall of the container is compromised, the signal in the sensor layer is altered by the disturbed shards cutting the signal cable, thus allowing for the detection of a rupture, vandalism or an unauthorized access attempt, The containment layers may be composed of a gel or rubber material to slow leakage.
