The invention discloses an
experimental system used for simulating severe accident conditions of the containment of a
nuclear power plant and an implementation method thereof to overcome the problem that comprehensive
simulation of severe accident conditions of the containment of a
nuclear power plant cannot be realized in the prior art. The
experimental system comprises an experimental container, a first
pressure sensor arranged in the experimental container, a
data acquisition system, an exhaust pipeline, an air supply
system, a
hydrogen supply
system, a spray system, an
aerosol supply system, a cable
combustion product supply system, a
water vapor on-line supply system and at least four sampling pipelines, wherein the
data acquisition system is connected with the experimental container through multipoint thermocouples; the exhaust pipeline, the air supply system, the
hydrogen supply system, the spray system, the
aerosol supply system, the cable
combustion product supply system, the
water vapor on-line supply system and the at least four sampling pipelines are connected with the experimental container; and the
aerosol supply system is connected with the spray system. The
experimental system provided by the invention has a reasonable structure, can authentically and comprehensively simulate severe accident conditions in the
nuclear power plant and carries out
hydrogen elimination performance testing on a passive hydrogen recombiner on the basis of
simulation results; moreover, testing results approximately represent actual working conditions, so good
reference standards are provided for researching and designing of the recombiner.
