TANG Yujian NING Qingkun GONG Zhenbang LIU Shubin. Stress analysis of passive hydrogen autocatalytic recombiner[J]. Nuclear techniques, 2013, 36(4): 040647
Background: Passive hydrogen autocatalytic recombiner is a device for eliminating hydrogen in the containment of the nuclear power plant when severe accident occurs
avoiding hydrogen explosion.After the Fukushima nuclear accident
the nuclear power plants pay more attention to the role of Passive hydrogen autocatalytic recombiner.Purpose: This paper studies the stresses of passive hydrogen autocatalytic recombiner under the seismic and LOCA conditions.Methods: Modeling by using the finite element software ANSYS
the impacts of airflow load under the LOCA conditions are considered reasonably and the strength of passive hydrogen autocatalytic recombiner is also evaluated according RCC-M.Results: The results show that the model can meet the requirement of the standard document.Conclusions: This paper will provide technical support for stress analysis and evaluation of passive hydrogen autocatalytic recombiner.
