AI Technical Summary

Benefits of technology

The present inventor describes an improved method for controlling cool sources by adding active components like thermal storage devices or refrigerators that can help prevent damage from outside factors such as temperature fluctuations during winter months. Additionally, there are also improvements made on how well these systems work properly when installed correctly without any problems caused due to other parts being affected negatively (such as leaks). Overall, this technology enhances the security measures used within buildings while keeping them smaller overall size compared to traditional methods.

Problems solved by technology

This technical problem addressed in this patents relates to improving the security and stability of fuel cell systems during normal operations without sacrificial measures such as inspections and maintenance. Current methods involve multiple steps and potential failures like leakage of fluids caused by thermal stress issues. Therefore, new designs are needed to address these challenges while maintaining efficient operation under various conditions.

Embodiment Construction

[0075]In the present application as a whole, the terms “vertical”, “lower”, “upper”, “top”, “higher”, “bottom”, “top”, “below” and “above” are to be understood relative to a primary vessel filled with liquid sodium, as it is in the vertical operating configuration.

[0076]FIGS. 1 and 2 show a liquid sodium-cooled nuclear reactor (SFR) 1, with a loop architecture, with a system 2 for removing at least part of both the nominal power and the residual power of the reactor according to the invention.

[0077]Such a reactor 1 comprises a primary vessel 10 or reactor vessel filled with liquid sodium, referred to as primary liquid, and inside which the core 11, in which a plurality of fuel assemblies 110 are implanted, generating thermal energy through the fission of the fuel, and lateral neutron shield (LNS) assemblies 11, are present.

[0078]The vessel 10 supports the weight of the sodium of the primary circuit and the internal components.

[0079]The core 11 is supported by two separate structures al

Abstract

The invention concerns a liquid metal-cooled fast-neutron nuclear reactor (1), comprising a system (2) for removing at least part of both the nominal power and the residual power of the reactor, which ensures, at the same time:
    • removal of the residual power in a totally passive manner from the initial instant of the accident;
    • removal of the heat through the primary vessel;
    • implementation of a final cold source (container with PCM) other than the sodium/air or NaK/air heat exchangers used in the prior art.
