THERMAL-HYDRAULIC STABILITY ANALYSIS OF SUPERCRITICAL WATER-COOLED FAST REACTORS

摘要

This paper summarizes the analysis methods and results of the thermal-hydraulic stability of asupercritical water-cooled fast reactor (SWFR). The stability analysis codes in the frequency domainare developed to study the thermal-hydraulic stability of SWFR which is a fast spectrum SCWRstudied by the University of Tokyo. The stability of SWFR for full-power and partial-poweroperation is investigated. The stability criterion can be satisfied at normal operation through settingan appropriate orifice pressure drop coefficient.
