Conference Article: Safety-related experiences with the AVR reactor
Krueger, K.J.; Ivens, G.P. (Arbeitsgemeinschaft Versuchs-Reaktor G.m.b.H., Duesseldorf (Germany, F.R.))Abstract
The 15 MW nuclear power station of the AVR is in operation since 1967. The operational results have clearly demonstrated its high safety potential. The fuel elements have shown good retention properties for fission products which lead to a low activity in the coolant gas, on the primary circuit surfaces and the deposited graphite dust. As a result the activity release into the atmosphere is low. The calculated maximum dose in the surrounding of the plant is less that 1 mrem/year. In case of a loss of coolant accident the activity inventory of the coolant would flow into the containment but would not reach the environment. But even if the activity would be released the maximum radiation dose in the environment would be negligible.
