摘要
Abstract
Advanced Secondary Passive(ASP)heat removal system was designed to cope with Station Blackout(SBO)accident in small reactors.To investigate the operational characteristics of the ASP system in small reactors,an existing ASP Test Facility(ASPTF)was adaptively modified based on scaling criteria.The system analysis code was revised according to the flow and heat transfer characteristics of the Helical Once-Through Steam Generator(HOTSG),and a computational model for the ASPTF was established.Using this model,studies were conducted to examine the effects of various factors on ASP system performance.Calculation results indicate that the operation model of makeup water tank significantly influences flow rate peak and pressure peak during ASP operation,with simultaneous activation of the makeup water tank and Heat Exchanger(HE)proving to be the optimal operation mode.Adjustments in pipeline resistance,valve actuation time,and initial water inventory in the HE tube-side showed minimal impact on system characteristics.The water replenishment capacity of the makeup water tank critically affects the operational stability of the ASP system.关键词
