During a severe accident in nuclear reactors, the core may melt and relocate into the lower
head. The decay power in the accumulated melt pool will threaten the integrity of the reactor …

During a severe accident in light water reactors, the core may melt and relocate into the
lower plenum of the reactor pressure vessel. The decay heat will threaten the structural and …

Abstract The COPRA (COrium Pool Research Apparatus) facility was designed to
investigate the in-vessel molten corium pool behavior for the in-vessel corium retention …

Large scale COPRA experiments were performed to study the natural convection heat
transfer in corium pools inside the reactor pressure vessel lower plenum during severe …

In-vessel retention (IVR) has been proposed as an effective mitigation strategy during
severe accidents in pressurized water reactors (PWRs). To help understand better the …

This paper presents the results from COPRA eutectic molten salt tests, which were carried
out to investigate the simulant effect on corium pool natural convection heat transfer …

The heat transfer characteristics during different transients are the critical problems in the
study of thermal behaviors in volumetrically heated corium pools. In this paper, the COPRA …

This study described the natural circulation and heat transfer of a molten pool in a
specifically designed core catcher conceived for a pressurized water reactor. In addition to …
