Background: One of the most advanced nuclear power technology

the first AP1000 reactor is under construction in China.Modularization is one of the main characteristics for AP1000 nuclear plant building.Module wall with steel face plate is used instead of reinforced concrete structure wall.A number of OLP embedments need to be installed into the module wall to connect other structures such as pipes

equipments

operation platforms and any other component attached to the module wall.Therefore

the design of embedment is very important in AP1000 structural design.Purpose: A finite element analysis method and tool for embedment design is needed for convenience.Methods: This paper applies the self-developed GTStrudl command template and VBA macro program for embedment capacity calculation and evaluation based on Microsoft Excel to the embedment design.Results: A Microsoft Excel template for embedment design is developed.Conclusions: The analysis method and template brings reasonable results and may provide some help and use for reference for the engineering practice.
