DEBRIS experimental setup

DEBRIS experimental setup is intended to investigate the hydrodynamic effects in case of pipeline ruptures at VVER NPPs.

DEBRIS experimental setup allows:

  • to examine the parameters of debris formed close to piping ruptures and the hydrodynamic effects of water jets, shockwaves, reactive forces, as well as the wave effects on removable and non-removable pipe insulation covers in case of pipeline ruptures at VVER NPPs
  • to carry out the experiments to verify computer codes and to simulate and assess disruption of insulation covers for different pipelines and equipment components

DEBRIS experimental setup:

  • NPP pipeline model
  • bursting disk assembly that serves as a ruptured pipeline
  • support frame for targets
  • air compressor
  • experimental measurement system
  • data acquisition and control system of a large-scale facility

In experiments a water get is simulated flowing out of a ruptured pipeline of VVER NPP.
