Key phenomena in the cooling states of underwater debris beds were classified based on
the premise that a target debris bed has a complicated geometry, nonhomogeneous …

In the context of light water reactor severe accidents analysis, this paper is focused on one
key parameter of in-vessel corium phenomenology: the immiscible phases stratification and …

Given the severe accident of a light water reactor (LWR), stratification and
solidification/melting are important phenomena in melt corium behavior within the reactor …

During a severe accident in a nuclear reactor, the melting of the core may lead to the
formation of a multiphase liquid pool (corium) in the vessel lower head. The heat transfer at …

The ternary mixture of uranium, oxygen and zirconium is investigated as a minimal model for
corium, the mixture that forms after the meltdown of a nuclear reactor. Like corium, UO-Zr …

ABSTRACT In February 2019, TEPCO and TOSHIBA designed a robot that can handle the
debris, performed a trial investigation of primary containment vessel (PCV) of the Fukushima …

Stratification behavior is of great significance in the late in-vessel stage of core melt severe
accident of a nuclear reactor. Conventional numerical methods have difficulties in analyzing …

This paper is the first part of the summary overview which presents the results of IBRAE's
work over the last 11 years to study the severe accident at Unit 1 of Fukushima Daiichi …

Liquid pools composed of molten multicomponent materials are often multiphase systems
and their behaviour is complex because the associated non-miscible phases can be …

The characteristics of the heat transfer and the calculation of heat flux in metal layer are both
the critical problems for in-vessel retention (IVR) strategy. Turbulent convection occurs in the …
