[en] Automatic translation: The chairman of this meeting will take the detailed minutes of this meeting Working group, Mr. Karcher. There were those at CEA, HOBEG, HRB, AVR, DRAGON, EURATOM, CEGB and RFLSpringfields The methods developed for the investigation of graphite corrosion under HTR conditions were compared and discussed with regard to a standard test (see Table 1). (EURATOM will no longer be active in this area in the future.) In the opinion of the participants, the test of the RFL in Springfields comes the Operating conditions in an HTR closest. The German side advocated a rapid test for quality control, roughly corresponding to the previous NUKEM / HRB / AVR standard test, in addition to one Standard corrosion test under approximate reactor operating conditions. It was agreed that CEA, RFL and HOBEG graphite or matrix samples Send to the other laboratories for the next meeting to be able to compare the results obtained in the various tests (a minimum of five samples of one type of material per experiment). The next meeting is planned for November.
