The MR materials testing reactor has been operational in the Kurchatov Institute, Moscow from 1965 to 1992. A very complex data acquisition and information system of the reactor has been designed, developed and implemented at the reactor by the Applied Reactor Physics Department. The core resident database handling and the graphical user interface was developed by MTA SZTAKI, Budapest. The system included five primary data acquisition computers of TPA 11/70 type, three VAX 780 type mainframes and 12 IBM PC compatible graphics workstations.

1000 analogue inputs were received and processed in every second, 1056 discrete inputs were registered with a resolution of 100 msec. About 300 technological schemes were available on the screens of the workstations. Dedicated workstations served the operators of the various experimental loops. An on-line, fault-tree based disturbance analysis module provided early detection of any failure in the system. The highly redundant system automatically reconfigured itself in case of any failure in any of its main hardware components. Unfortonately, the system was removed from operation before its full scope utilisation, parallel to the shutdown of the test reactor.
