Analysis and Design Recommendation on Rabbeted Capping Plate of Equipment Cell in Nuclear Chemical Facility

Rabbeted capping plates are widely used in the roof of equipment cells in order to meet the requirements of nuclear radiation protection. The key considerations in the design include vertical load, seismic load and repair load. This article establishes T-shaped and Z-shaped plate model via FEM software (ANSYS), analyzes the bearing capacity and displacement distribution in different load cases, and provides recommendations to the design and construction accordingly.
