Modular Shield Panel System for Radioactive Waste Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current storage container shielding systems for radioactive waste lack adjustability and efficiency, often requiring more shielding than necessary, which is not economical and does not account for varying radiation levels, and there is a need for a modular, compact solution to prevent the escape or ingress of harmful particles or rays.
Innovation Solution
A modular, removable shield panel system that allows for flexible configuration and reconfiguration of shielding on storage containers, using adjustable shield mounts and panels composed of various materials to optimize shielding based on the activity level of the waste, reducing the overall shielding material usage and storage footprint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed shielding systems are used for storage containers, then radiation protection is provided, but the shielding cannot be adjusted for varying radiation levels and more material than necessary is used
Solution Approach 1:
The shielding system is divided into multiple removable panels that can be independently configured. Each panel can be attached or detached from the storage container based on the specific radiation protection needs, allowing the quantity of shielding material to be optimized for each storage scenario rather than using fixed excessive shielding for all containers.
Solution Approach 2:
The shielding system transitions from a static fixed configuration to a dynamic reconfigurable system. The removable panels can be dynamically added or removed based on the radiation level of the stored material, enabling the shielding capacity to adapt to varying requirements and reduce material usage when full shielding is not needed.
2Reliability
If uniform shielding is applied to all storage containers, then consistent protection is achieved, but storage capacity is reduced due to excessive shielding material
Solution Approach 1:
Instead of applying uniform shielding to all containers, the system allows for localized shielding where panels are attached only to containers or container sides that require radiation protection. This enables consistent protection where needed while minimizing the overall shielding material volume and preserving storage capacity.
Solution Approach 2:
The removable shielding panels serve multiple functions: they can be attached to different containers, positioned at different locations, and configured in various arrangements. This universal applicability allows the same shielding panels to provide consistent protection across multiple storage scenarios without requiring excessive material for each individual container.
3Productivity
If removable shield panels are implemented, then shielding efficiency is improved and material usage is reduced, but system complexity increases
Solution Approach 1:
While segmentation into removable panels improves shielding efficiency by allowing precise material placement, the panels are designed with standardized interfaces and mounting mechanisms that simplify the configuration process. The modular segments can be easily attached and detached without requiring complex assembly procedures, thus maintaining productivity benefits while controlling system complexity.

AI summary
Disclosed herein are systems and methods for a modular reconfigurable shielding system for one or more storage containers in temporary or long term storage. The system comprises shield panels which may be used to shield external faces of containers in a storage configuration to reduce the overall amount of shielding required in a storage facility. Reducing the amount of shielding reduces the storage footprint of each container thus increasing storage capacity and efficiency of the storage facility. The modularity of the shield panels allows storage containers to be easily added and removed from the storage configuration. Additionally, modular shielding allows the amount and type of shielding to be easily reconfigured for differing requirements and storage contents.
