[0072] (c) The floating nuclear power plant reactor layout structure of the present application arranges the rotating equipment steam turbine generator set along the platform axis, which minimizes the mutual influence between the hull platform and the steam turbine generator set during operation;

[0073] (d) The floating nuclear power plant reactor layout structure of the present application arranges the auxiliary room on the upper living deck of the turbine room to further reduce the width of the turbine room, which is conducive to forming a slender hull platform structure; secondly, the electrical and instrumentation equipment in the auxiliary room is arranged on the upper part of the hull platform, which is conducive to preventing the risk of flooding and increasing the reliability of power plant operation;

[0074] (e) The floating nuclear power plant reactor layout structure of the present application arranges part of the equipment in the steam engine room to the lower layer, arranges the electric feed water pump and condensate pump on the bottom layer of the hull, arranges the condenser on the lower deck layer, arranges the low-pressure heater on the upper deck layer, and arranges the steam turbine generator set on the main deck layer. Firstly, the requirements for the cavitation margin of the feed water pump and condensate pump are met, which is beneficial to the requirements for preventing water ingress to the steam turbine and improving the safety and reliability of the operation of the thermal system. Secondly, the equipment is arranged on the lower layer as much as possible to reduce the overall center of gravity of the steam engine room, which is beneficial to the stability of the hull platform. Moreover, the steam turbine generator set is placed on the main deck, which is beneficial to the later inspection and maintenance.
