Storage of Thermal REactor Safety Analysis data
Description

The tests conducted in the PRELUDE facility help to validate key technical options for PEARL:

  • Induction heating to obtain heating sequences between 100-300 W/kg with homogeneous distribution in the different particle beds (slightly oxidised steel balls with 1, 2, 4 and 8 mm diameters), as well as to reach a temperature of 1,000°C at the hottest spot in the debris bed.
  • Material of the test section ensuring the thermomechanical resistance of the tube containing the particles bed,
  • Instrumentation to record the fi rst thermohydraulic measurements at atmospheric pressure when refl ooding the particle bed (about 25 kg) heated to of 400, 700 and 1,000°C.

This modular facility will remain operational to support the larger-scale PEARL facility (debris bed of about 500 kg) for complementary separate effects tests.

Facility is not operating, now called PEARL.
