No full textFPT4 is the third test in the PHEBUS program of integral experiments aimed at the study of the release, transport and deposition of fission products in a severe reactor accident. The purpose of the performed ICARE2 calculations is to support a realistic scenario concerning the debris bed thermal behaviour and molten pool formation. The comparison experiment calculation shows a good agreement up to 2200 K. At higher temperature is necessary to assume a steam by-pass through the thermal shroud to reproduce the measured temperatures. With this hypothesis, also the final molten pool configuration is well calculated
Survey on FPT-3 Objectives and Pre-Test Analyses
No full textIn the FPT-3 test, a B4C control rod will be used instead of the silver-indium-cadmium absorber rod used in the previous experiments. The impact of the B4C (oxidation, interaction with the stainless steel clad) has been analised in order to design the test section. In order to define the test scenario a simple B4C oxidation model has been implemented in the ICARE2 code. Experimental and analytical works on the B4C oxidation are on going
PHEBUS FPT3: Preliminary Investigation for Designing a Bundle with a B4C Rod
No full textIn the framework of the preliminary studies to define the PHEBUS/FPT3 test bundle design, two sets of results are given hereafter : The B4C, UO2 and stainless steel masses involved in various reactor types using B4C absorbers as well as in the integral experiments already performed with such a material. The fraction of B4C liquefied by interaction with the stainless steel cladding as modeled by ICARE2, for different stainless steel thickness, during thermal transient prototypic of FPT2 conditions

No full textThe following items are described : Objectives of the FPT3 experiments, Model of the B4C oxidation, ICARE2 calculations to define a preliminary scenario. A steam flow rate of 0.3 g/s during the oxidation escalation leads to the required long steam starvation period
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
