Abstract

Supercritical CO2 (sCO2) is widely used in many industrial applications.The utilization of sCO2 power cycles has been gaining attention and first prototypes of the order of few MWe are being built.A European consortium led by University of Duisburg-Essen is investigating a sCO2 heat removal system (sCO2-HeRo) as a back-up cooling system, which efficiently removes residual heat from nuclear fuel without the requirement of external power sources.The sCO2-HeRo system applies a simple sCO2 Brayton cycle.This technical paper presents the first test results of the sCO2 turbomachine (TAC).The paper focuses on the validation of the calculated performance maps of the centrifugal compressor.The tests were performed in the newly built sCO2 experimental loop, which was constructed within the SUSEN (Sustainable Energy) project at Research Centre e (CVR).
