Storage of Thermal REactor Safety Analysis data

PACTEL is a volumetrically scaled (1: 305) facility including a pressurizer, high and low pressure emergency core cooling systems, and accumulators. The reactor vessel is simulated with a U-tube construction including separate downcomer and core sections. The core itself is consists 144 full-length, electrically heated fuel rod simulators. Component heights and relative elevations correspond to those of the full scale reactor to match the natural circulation gravitational heads in the reference system. Three coolant loops with double capacity steam generators are used to model six loops of the reference power plant. The facility is still in operation for example as an auxiliary system for the separate effect test facilities. Until now, 239 experiments have been carried out with the facility.
