AI Technical Summary
Existing micro nuclear reactors are difficult to operate for a long time in a compact space, and they suffer from problems such as neutron energy spectrum imbalance, low reactivity compensation efficiency and difficulty in passive heat dissipation, especially in underwater environments where safety and energy density are insufficient.
It adopts a supercritical carbon dioxide cooled pressure tubular reactor, uses heavy water moderator to change the neutron energy spectrum and match it with gadolinium-based combustible poison, combines radial reflector and non-uniform gadolinium poison distribution to optimize fuel assembly layout, achieve long-term stable operation, and improves safety through inert gas insulation and online monitoring mechanisms.
It achieves long-life operation at low enrichment levels, ensures thermal-hydraulic safety margin and safety under accident conditions, provides efficient energy output and stealth, and is suitable for nuclear power sources for underwater unmanned equipment.
