In-Core Instrumentation and Fast Digital Data Acquisition for the Sefor Nuclear Test Reactor

The primary purpose of the SEFOR nuclear test reactor is to measure the dynamic behavior of a fast reactor core. Special in-core instrumentation has been developed for fuel and sodium temperature and sodium flow rate measurements. Neutron detectors have been built and tested which will measure reactor power peaks up to 106 MW. A fast computer-controlled data acquisition system allows sampling rates up to 30,000 data/sec. The system provides for minor data reduction and analysis.
