Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If conventional nuclear power generation systems use heat exchangers and piping for thermal energy conversion, then nuclear energy can be converted to electrical energy, but the system complexity and capital costs increase significantly

Engineering Contradiction:
Improveenergy conversion efficiencyVSAvoidsystem complexity
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The patent combines the heat removal and energy conversion functions into a single integrated system. The working fluid directly contacts the nuclear fuel elements in the reactor core, absorbing thermal energy, and then expands through a turbine to generate electricity. This eliminates the need for separate heat exchangers and piping systems, reducing both device complexity and capital costs while maintaining energy conversion efficiency.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The working fluid serves multiple functions simultaneously: it acts as the coolant that removes heat from the nuclear fuel, as the working medium that drives the turbine for electricity generation, and as the propellant that can provide thrust for propulsion applications. This multi-functionality reduces the number of separate systems needed, thereby reducing system complexity and capital costs.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Power

If conventional nuclear power plants use large-scale reactors with complex thermal conversion machinery, then electrical energy can be generated, but the siting options are limited and capital costs are high

Engineering Contradiction:

Solution Approach 1:

The patent divides the nuclear power generation system into modular components that can be scaled and configured for different applications. The integrated reactor-turbine system can be designed in various sizes and configurations, allowing deployment in remote locations, on ships, or in space applications, thereby expanding siting options while maintaining electrical energy generation capability.

Solution Approach 1:

The patent merges the coolant and working fluid into a single integrated system. The working fluid directly absorbs thermal energy from the nuclear fuel elements and then expands through the turbine, eliminating intermediate heat transfer steps. This direct conversion process reduces thermal losses and improves overall energy efficiency while maintaining temperature control capabilities.

AI summary

Provided is an apparatus for generating electricity, mechanical energy, and/or process and district heat using a gas propellant chamber fueled with fissile material and enclosed in a sealed containment vessel which also contains an operating gas. The system allows for the operating gas to be compressed as it enters the nuclear fuel chamber where it is heated. As the operating gas exits the nuclear fuel chamber, the kinetic energy of the gas is converted to rotational energy by a variety of methods. The rotational energy is further converted to electricity, mechanical energy, and/or process and district heat. The operating gas circulates in the containment vessel and is cooled prior to re-entering the gas propellant chamber. The apparatus thereby provides a simpler and safer design that is both scalable and adaptable. The apparatus is easily and safely transportable and can be designed to be highly nuclear-proliferation-resistant.
