Molten Salt Reactor Slug Loading System with Terminal Sieve

The patent introduces an intermediary delivery system consisting of a chute and terminal sieve that acts as a mediator between the safe external environment and the hazardous molten salt environment. Solid fuel slugs are introduced through the chute from outside the reactor core, and the terminal sieve facilitates dissolution into the molten salt without requiring direct human intervention in the hazardous zone. This intermediary mechanism resolves the contradiction by enabling composition adjustment while maintaining operational safety.

The solid fuel slugs are prepared and staged in advance in a safe external location before being introduced into the reactor. The loading system allows pre-preparation of fuel components outside the hazardous environment, then delivers them when needed. This preliminary action enables the reactor to maintain continuous operation with pre-positioned fuel adjustments, resolving the contradiction between continuous operation and hazard avoidance.

The chute and terminal sieve serve as intermediary structures that enable safe fuel introduction without reactor shutdown. The system physically separates the fuel loading operation from the hazardous molten salt environment, allowing composition adjustment while the reactor remains operational. This intermediary approach resolves the contradiction by decoupling safety from continuous operation requirements.

The patent replaces the traditional mechanical approach of direct manual salt handling with an automated delivery system. Instead of mechanically manipulating molten salt (which would require shutdown), the system uses gravity-fed chute delivery and passive dissolution through the terminal sieve. This substitution enables continuous operation while maintaining safety by eliminating the need for direct mechanical interaction with hazardous materials.

The loading system is segmented into distinct functional components: an external loading assembly, a delivery chute, and a terminal sieve within the molten salt loop. This segmentation allows each component to be optimized independently and simplifies the overall system by breaking down the complex task of fuel introduction into manageable stages. The segmented approach resolves the contradiction by making the system adaptable while keeping individual components relatively simple.

The terminal sieve enables self-service dissolution of the solid fuel slugs into the molten salt without requiring external intervention. Once the slug is introduced through the chute, the molten salt naturally dissolves it through contact with the sieve structure. This self-service mechanism reduces system complexity by eliminating the need for complex mixing or dissolution equipment, while still achieving real-time composition adjustment.
