Corium kinematic viscosity measurement

Nuclear Engineering and Design, 2000
Abstract Viscosity is one of the important properties which along with thermal conductivity and coefficient of volumetric expansion, determines convection in molten corium in the case of unfavourable progress of a severe accident in nuclear reactors. The viscosimetric attachment has been designed, developed and built for the purpose of measurement of

Extensive corium grafts.

Acta chirurgiae plasticae, 1992
Even in our times of revolutionary advances in the technology and operative techniques in plastic surgery, the corium is a material with multiple applications and can be found in the patient at varying thickness. The aim of the article is to show that its indication to reinforce flaccid musculature or to cover muscular defects of the abdominal wall is ...

The Dehiscence of Mycenastrum Corium

Mycologia, 1930
The Lycoperdales is a group of fungi to which the majority of "puffballs," "devil snuffboxes," etc, belong. Their methods of dehiscence are many and more or less characteristic and constant for certain genera. The manner in which the peridia split is often made the basis for generic distinctions.

Corium crust strength measurements

Nuclear Engineering and Design, 2009
Abstract Corium strength is of interest in the context of a severe reactor accident in which molten core material melts through the reactor vessel and collects on the containment basemat. Some accident management strategies involve pouring water over the melt to solidify it and halt corium/concrete interactions. The effectiveness of this method could

Viscosity models for corium melts

Nuclear Engineering and Design, 2001
When a solid phase is in equilibrium with a liquid (partial crystalization), additional information is necessary to estimate the rheological behaviour of such a two-phase fluid. During the crystallization process it is possible to estimate the viscosity of the liquid phase by considering the evolution of its composition during the solid phase deposit ...

Management options for Fukushima corium

Progress in Nuclear Energy, 2016
Abstract The loss of core cooling for units 1–3 during the accident at Fukushima Dai-ichi caused major fuel damage. Although full details are not yet available, fuel melting produced corium within the reactor pressure vessels that has, to an unknown degree, melted through into the primary containment.

Oxidation kinetics of corium pool

Nuclear Engineering and Design, 2013
Abstract Experimental, theoretical and numerical studies of oxidation kinetics of an open surface corium pool have been reported. The experiments have been carried out within OECD MASCA program and ISTC METCOR, METCOR-P and EVAN projects. It has been shown that the melt oxidation is controlled by an oxidant supply to the melt free surface from the ...

Molten corium oxidation model

Nuclear Engineering and Design, 2005
Abstract In order to model oxidation of Zr–O and U–Zr–O melts, post-test appearance of refrozen oxidised melts in the CORA and QUENCH bundle tests performed at the Research Centre Karlsruhe (FZK) are analysed. Furthermore, data from new separate effect tests on ZrO 2 crucible dissolution by molten Zry, specially designed for investigation of long ...
