Research on the Design and Analysis Methods of Ventilation Scheme for Pressurized Water Reactor Head Structure
To further shorten the downtime for refueling and maintenance in order to enhance the economic efficiency of nuclear power plants,it is necessary to optimize and improve the ventilation scheme for the reactorhead structure.Considering the complexity involving multiple disciplines in optimizing and improving the ventilation of the head structure,a design analysis method oriented towards forward design has been proposed.This method establishes a list of requirements that cover various professional needs,analyzes the impact of optimization schemes,clarifies subsequent simulation calculations and analysis work that needs to be carried out,ultimately demonstrating the feasibility of the optimized scheme through simulation analysis of flow field and temperature field,and identifying future directions for optimization.This study provides a systematic design analysis method for optimizing ventilation cooling schemes for top structures,which can be widely applied to similar optimization designs in nuclear power equipment.
