Existing devices for transferring spent fuel between storage pools in nuclear power plants face challenges in maintaining the vertical orientation of spent fuel during transfer, which affects handling stability and efficiency, especially when additional storage capacity is needed.
Innovation Solution
A spent fuel transfer device comprising a vertically oriented transfer container with cooling holes, a guide frame, and a transfer unit that includes a pulley system and winch system to maintain vertical orientation and facilitate movement along a guide rail, ensuring stable and efficient transfer between storage pools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If spent fuel is transferred between storage pools using existing handling machines, then transfer capability is achieved, but vertical orientation of spent fuel cannot be maintained
Solution Approach 1:
The transfer system is divided into separate functional components: a transfer container for holding spent fuel, a guide frame for providing vertical guidance, and a transfer unit for movement. This segmentation allows each component to specialize in maintaining vertical orientation while enabling transfer capability.
Solution Approach 2:
The guide frame acts as an intermediary structure between the transfer container and the storage pools. It provides a vertical guidance path that mediates the transfer process, ensuring the spent fuel maintains vertical orientation throughout the transfer operation.
2Quantity of substance
If additional storage pool is built to increase storage capacity, then storage capacity requirement is met, but device complexity increases
Solution Approach 1:
The transfer container and guide frame are designed as universal components that can operate between multiple storage pools. The same basic transfer device structure can be reused for different transfer operations, reducing overall system complexity despite increased storage capacity requirements.
