Engineering Contradiction Analysis
1Productivity
If traditional transport container design is used, then nuclear safety requirements are met, but transport capacity is small and efficiency is low
Solution Approach 1:
The transport container is divided into multiple independent storage chambers (first storage chamber, second storage chamber, etc.) separated by partition walls. Each chamber can independently store fuel assemblies, allowing parallel loading and transport of multiple fuel containers simultaneously, thereby increasing overall transport capacity without compromising safety
Solution Approach 2:
The design allows nested storage configuration where fuel assemblies are placed within storage chambers that are themselves within the main transport container. The first fuel assembly is stored in the first storage chamber, and the second fuel assembly is stored in the second storage chamber, creating a nested structure that maximizes space utilization while maintaining safety distances
2Quantity of substance
If transport container capacity is increased, then more fuel can be transported, but safety protection against accidents may be compromised
Solution Approach 1:
By segmenting the container into multiple isolated storage chambers with partition walls, the patent increases transport capacity while maintaining safety through physical separation. Each chamber acts as an independent safety zone, preventing accident propagation between fuel assemblies even as total capacity increases
Solution Approach 2:
Different regions of the transport container are designed with different functional qualities - storage chambers for fuel containment, partition walls for isolation, and specific structural reinforcements for safety. This localized optimization allows capacity increase in storage regions while maintaining or enhancing safety in protective regions
