Description
According to IAEA statistics, more than 300 research reactors are in operation worldwide with power levels ranging between several milliwatts and the 250 MW Advanced Test Reactor in Idaho, USA. With research reactors of the ≥ 100 kW power category, impacts on third parties of accidents in these reactors cannot be excluded. Consequently, the safety status of these reactors must be, and will be, inspected whenever plant modifications become necessary. In Western Europe, 35 research reactors with powers ≥ 100 kW are at present in operation. More than seventy percent of the reactors were purchased over twenty years ago. The average age of the research reactors still in operation is 24.2 years. Examples of backfitting measures and of the adaptation to the current state of the art are represented by the research reactors in Brunswick (FMRB) and in Geesthacht (FRG-1 and FRG-2), which are discussed in detail in the report.

Die Statistik der IAEO weist weltweit ueber 300 in Betrieb befindliche Forschungsreaktoren aus. Der Leistungsbereich reicht dabei von Milliwatt bis zum 250-MW-Advanced Test Reactor, Idaho, USA. Bei Forschungsreaktoren der Leistungsklasse ≥ 100 kW koennen nicht von vornherein Stoerfallauswirkungen auf Dritte ausgeschlossen werden, es muss und es wird daher bei Aenderungen der Anlage der Sicherheitsstand zu ueberpruefen sein. In Westeuropa sind derzeit 35 Forschungsreaktoren mit Leistung ≥ 100 kW in Betrieb. Diese 35 Forschungsreaktoren wurden zu mehr als 70% vor mehr als 20 Jahren gebaut. Das mittlere Alter der noch in Betrieb befindlichen Forschungsreaktoren berechnet sich zu 24,2 Jahren. (orig.)Additional details
