1. An integrated passive reactor system comprising a pressure vessel, a containment vessel arranged outside the pressure vessel and a reactor core arranged inside the pressure vessel, wherein
the integrated reactor system includes a secondary side passive residual heat removal system loop,
the secondary side passive residual heat removal system loop comprises
a primary loop heat exchanger arranged inside the pressure vessel
and a passive residual heat removal heat exchanger arranged outside the containment vessel,
the primary loop heat exchanger is arranged above the reactor core, and
the passive residual heat removal heat exchanger is arranged in a water tank which is fixed outside the containment vessel,
the primary loop heat exchanger and the passive residual heat removal heat exchanger are connected by a heat exchanger inlet pipeline and a heat exchanger outlet pipeline,
the pressure vessel comprises a first-layer shell and a second-layer shell arranged on the top of the first-layer shell to form a top double-layer structure with the first-layer shell,
wherein the first-layer shell encloses a first space and the second-layer shell encloses a second space fluidly isolated from the first space,
a pressurizer is fixedly installed within the second-layer shell,
and a surge pipe is provided between the pressurizer and the first-layer shell,
a plurality of primary loop-related pipelines are communicated with the second-layer shell,
and the upper end of each of the plurality of primary loop-related pipelines penetrates through the second-layer shell and extends above the second-layer shell.
