Solution Overview
Problem
Existing power generation technologies, such as hydroelectric, wind, solar, and nuclear, face challenges including high upfront costs, environmental impact, intermittency, and safety concerns, making them less viable alternatives to fossil fuels.
Innovation Solution
The use of offshore nuclear power generation facilities utilizing modular reactors housed in monopile structures, which are installed in an earthen bed beneath a body of water, providing a scalable, safe, and cost-effective carbon-neutral power source with reduced construction delays and enhanced safety features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional nuclear power plants are constructed, then reliable carbon-neutral power generation is achieved, but high upfront costs and long construction delays occur
Solution Approach 1:
The patent divides the nuclear power plant into modular units that can be manufactured separately and then assembled on-site. Each module includes its own reactor core, containment structure, and associated equipment, allowing for parallel construction and reduced overall project timeline while maintaining the reliability of nuclear power generation.
Solution Approach 2:
The modular reactor units are pre-manufactured and pre-assembled in controlled environments before being transported to the installation site. This preliminary action allows for quality control and optimization during manufacturing, reducing on-site construction time and ensuring reliable power generation upon completion.
2Reliability
If conventional nuclear power plants are built, then carbon-neutral power is produced, but radioactive waste disposal and safety accidents are concerns
Solution Approach 1:
The patent extracts and separates the waste management function from the power generation modules. Each modular unit includes its own dedicated waste storage and processing systems, allowing for isolated handling of radioactive materials and simplified disposal procedures while maintaining safe operation of the reactor core.
Solution Approach 2:
The modular design incorporates built-in safety features and redundant systems in each unit, including emergency cooling systems, radiation shielding, and containment structures that are pre-engineered to prevent accidents. These safety mechanisms are integrated into the basic module design before deployment.
3Ease of manufacture
If offshore monopile structures are used, then construction costs are reduced and safety is enhanced, but installation complexity increases
Solution Approach 1:
The patent employs nested monopile structures where one monopile is placed inside another, creating a layered containment system. This nesting approach simplifies the overall structure by using the same basic monopile design repeated at different scales, reducing manufacturing complexity while enhancing safety through multiple containment barriers.
Solution Approach 2:
The monopile structure serves multiple functions simultaneously: it provides structural support for the reactor, acts as a containment barrier, serves as a radiation shield, and functions as an anchor in the seabed. This multi-functionality reduces the need for additional specialized components, simplifying the overall installation process despite the complex offshore environment.
