Abstract
The Fukushima accident reveals the need for additional safety systems for nuclear power plants. One promising option is the supercritical carbon-dioxide (sCO2) heat removal system, which consists of a simple Brayton cycle. This study provides an overview of the extensions and validation of the thermal-hydraulic system code ATHLET for the simulation of sCO2 power cycles, especially with regard to the sCO2 heat removal system. The properties of CO2, heat transfer and pressure drop correlations, as well as compact heat exchanger and turbomachinery modelling are considered.
Kurzfassung
Der Unfall von Fukushima offenbart den Bedarf an zusätzlichen Kühlsystemen für Kernkraftwerke. Eine vielversprechende Option ist ein Nachwärmeabfuhrsystem bestehend aus einem einfachen Joule-Kreisprozess mit superkritischem Kohlenstoffdioxid (sCO2) als Arbeitsmedium. Diese Studie gibt einen Überblick über die Erweiterungen und die Validierung des thermohydraulischen Systemcodes ATHLET für die Simulation von sCO2-Kreisprozessen, besonders im Hinblick auf das sCO2-Nachwärmeabfuhrsystem. Die Stoffdaten von CO2, Wärmeübergangs- und Druckverlustkorrelationen, sowie die Modellierung von Kompaktwärmeübertragern und Turbomaschinen werden berücksichtigt.
