Research and Development Program to Protype Plant Nuclear Process Heat. Annual Report 1990. Development work on component Trial cycle, for component testing and for the nuclear heat generation system

Automatic translation: Component test cycle (KVK): The KVK achieved an availability of 99%. The total operating time is 20,585 hours, of which 7395 hours above 900 ° C and 12259 hours above 700 ° C. During the operating phase, the test instrumentation and the data acquisition systems were looked after. The fourth test phase for the NWA cooler began on 02/08/90 and ended on 03/13/90. The NWA cooler was in Steam generator operation together with the in September 1989 investigated built-in core connector. From 09/04/90 to 09/23/90 were attempts to static and dynamic Stability carried out on the operating steam generator in order to reduce the Verify arithmetic codes. In the last quarter of 1990 the KVK was shut down and the Work on storage and conservation started.
