Abstract

The invention provides a fuel building hydrogen control experiment bench and a fuel building hydrogen control method. The fuel building hydrogen control experiment bench comprises a fuel building simulated body, a fuel assembly simulated body, a gas injection system, a water injection system, a spraying system, a cooling circuit and a measurement control system, wherein the fuel building simulatedbody comprises an upper house body and a spent fuel pool; helium, steam and air are distributed in simulated distribution in the upper house body; and the gas injection system comprises a helium supply component and a steam generator. According to the fuel building hydrogen control experiment bench and the fuel building hydrogen control method provided by the invention, a small-scale experiment platform is utilized, hydrogen distribution characteristics in the fuel building are subjected to experimental study under serious accident conditions of a nuclear power plant with partial water loss and total water loss, key experimental data is acquired, and hydrogen risk is well controlled.

Description

technical field [0001] The invention belongs to the field of hydrogen gas control technology of nuclear power plant fuel building, and more specifically relates to a fuel building hydrogen control test bench and a fuel building hydrogen control method. Background technique [0002] In March 2011, the Fukushima nuclear power plant in Japan suffered a serious accident of long-term power outage. During the accident, active safety facilities such as emergency core cooling and waste heat removal system stopped working; passive safety facilities such as core isolation cooling and high-pressure safety injection system worked intermittently within the design working time limit, and the core cooling effect was not obvious. Within 6 to 7 hours after the passive safety device stopped working, the power plant personnel did not take any measures to cool the core. Afterwards, the power plant personnel restored the water injection function of the primary circuit, but it was too late, and ...
