SARNET: Severe accident research network of excellence

Experimental results of the QUENCH-16 bundle test on air ingress

“…Experimental and analytical works on air ingress were performed within the EC 4 th and 6 th Framework Programs 1,2 . Numerous single effect tests on cladding oxidation in air were performed at ANL 3 (temperatures 573-1173 K), AEKI 4 (temperatures 873-1773 K), and KIT 5,6 (temperatures 873-1873 K).…”

A comparison of core degradation phenomena in the CORA, QUENCH, Phébus SFD and Phébus FP experiments

“…These issues were and will be tackled on a cooperative basis as was the case in the SARNET project for example (Albiol et al, 2010;Van Dorsselaere et al, 2011), indeed the separate-effects experiments outlined here benefited from such cooperation, for example regarding air ingress and boron carbide (Haste et al, 2012) interactions. On-going work to resolve these issues is summarised for example in in both the experimental and model development areas; for example the test QUENCH-DEBRIS for debris bed reflood at Karlsruhe and corresponding experiments at IRSN in the PRELUDE/PEARL series.…”

Simulation of Ex-Vessel Steam Explosion

“…The aim of the comprehensive analytical program is to increase the capability of FCI models and codes for use in reactor analyses. Due to the high risk significance of the steam explosion phenomenon for the containment integrity, the ex-vessel FCI issue is one of the six high priority safety issues, which were identified in the EU (European Union) network of excellence SARNET (Severe Accident Research NETwork of Excellence) Phase 1 (Albiol et al, 2008;Schwinges et al, 2010). The purpose of the SARNET network of excellence, which was founded in the year 2004, is to integrate European research capabilities on severe accidents in order to enhance the safety for the existing and future nuclear power plants.…”
