The 16th International QUENCH Workshop took place during 16-18 November 2010 at Karlsruhe Institute of Technology in Germany. About 60 scientists from 10 countries participated in the workshop.
As every year, the current status of the available experimental data base and the modelling activities in various countries were discussed. The results of the bundle tests QUENCH-14/15 (behaviour of M5 and ZIRLO advanced cladding alloys) and first results of the commissioning test QUENCH-L0 of the new LOCA series, as well as reports from the PARAMETER program in LUCH (Russia) were presented. Modelling and code applications to the QUENCH and PARAMETER tests were the main topics on the second day. Presentations on the third day were devoted to recent studies on core degradation and chemical interactions of core materials under severe accident conditions, with the oxidation, reaction with nitrogen, hydrogen absorption as well as the application of neutron radiography as topics among others. Future developments of the QUENCH programme have been discussed, too.
Topical Meeting on QUENCH-Debris
In connection with the QUENCH Workshop, a SARNET2 WP5 Topical Meeting on QUENCH-Debris and related experiments was organised. The main goal of this meeting was the presentation of the status of preparation of the QUENCH-Debris bundle tests. Furthermore, the most reasonable scenarios for the two experiments planned to be performed within SARNET2 were discussed taking into account a) most needed information, b) experimental boundary conditions and c) other coolability experiments currently underway (DEBRIS in IKE, PRELUDE/PEARL in IRSN).
The participants agreed that the first test should be performed with hafnium components and including the debris formation phase. The conditions of the second test will be discussed after conduct of the first test, including the option of use of a pre-formed debris bed.
