The small nuclear reactor power supply is highly versatile, safe, and efficient, with the added benefits of modular manufacturing, portability, and self-regulation. With an electrical power range from kilowatts to megawatts, it can operate continuously for 10 years without the need for shutdown or material replacement. Its compact size, light weight, and ease of transportation make it an ideal long-term and stable power source for emergency response in remote areas and nuclear power plants. This innovative solution effectively addresses the challenges of low efficiency, difficult fuel supply, and significant safety risks associated with traditional power generation methods, presenting promising applications for the future.

This project focuses on addressing the power supply needs of mobile nuclear reactors. It involves the conceptual design study on the power supply of 8MWe helium xenon cooled mobile solid nuclear reactors. The project aims to establish a design approach for achieving ultra-long life and inherent safety of solid nuclear reactors. Additionally, it seeks to develop intelligent autonomous control methods suitable for land mobile scenarios, advance the design technology of three machine integration and printed circuit heat exchangers (PCHE), and establish an efficient Brayton energy conversion system. Furthermore, the project aims to break through lightweight shielding structure design technology to meet radiation safety requirements while optimizing weight and volume for mobile scenarios. Ultimately, the project aims to establish a comprehensive system numerical simulation platform and discuss key technologies. Specifically, it will address the following four key scientific and technological issues:

1.Overall conceptual design and numerical platform construction of intelligent small-scale land-based mobile nuclear reactor power supply.

2.Optimization design method for a compact solid core.

3.Performance matching mechanism of integrated and efficient Brayton cycle system.

4.Lightweight shielding design scheme and structural optimization method.
