Experimental nuclear power plant, Jlich; high-temperature reactor with a gross electrical output of 15 MW. Nuclear commissioning on 26th Aug. 1966, final shutdown on 1st Dec. 1988. The cumulated power generation amounted to 1.7 TWh. The reactor was built according to the concept of a pebble-bed reactor developed by Prof. Schulten. The AVR was primarily used to gain operating experience for the development of hightemperature reactors. The AVR was the first power reactor completely developed in Germany
