Solution Overview
Problem
Nuclear installations face challenges in maintaining operations during accidents due to failures in cooling systems, especially when supply facilities are damaged, leading to environmental hazards, and existing technologies do not provide a self-sustaining, independent emergency supply system.
Innovation Solution
A mobile container system equipped with a high-performance turbo-charged Diesel motor, a self-priming spiral casing pump, a generator, a fuel tank, and a transformer, which can be positioned stably and transportably, allowing for independent operation to revitalize or bypass the cooling system and provide power, with a fuel capacity enabling continuous operation for several days.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mobile container system with integrated motor, generator, pump, and fuel tank is used to provide independent emergency supply to nuclear installations, then the reliability and independence of the emergency supply system is improved, but the device complexity and transport difficulty increase
Solution Approach 1:
The patent combines multiple functional components (motor, generator, pump, fuel tank, transformer) into a single integrated mobile container system. This merging approach enables the system to provide both mechanical power (through the pump) and electrical power (through the generator) simultaneously, improving reliability by ensuring that all necessary components are available together in one self-contained unit that operates independently of the nuclear installation's infrastructure.
2Stability of the object's composition
If the fuel tank is arranged in the area of the center of gravity of the container, then the stability and transportability of the container is improved, but the available space for other components is reduced
Solution Approach 1:
The fuel tank is strategically positioned in the container's center of gravity area, functioning as a counterweight that stabilizes the container during transport and operation. This placement ensures balanced weight distribution, preventing tipping and improving handling stability, while the fuel tank's mass itself serves as the counterbalancing element rather than requiring additional stabilization mechanisms.
3Use of energy by moving object
If the pump and generator are functionally connected to the motor for actuation, then the system efficiency and energy utilization are improved, but the device complexity increases
Solution Approach 1:
The motor serves multiple functions within the system by being functionally connected to both the pump and the generator. It can actuate the pump to drive cooling water circulation and simultaneously power the generator to produce electrical energy. This multi-functionality improves energy utilization efficiency, as the single motor converts fuel energy into both mechanical work and electrical energy, reducing the need for separate power sources.
