MYRRHA/FASTEF objectives

  • To be operated as a flexible fast spectrum irradiation facility working

in subcritical and critical mode allowing for:

  • fuel developments for innovative reactor systems;
  • material developments for GEN IV systems;
  • material developments for fusion reactors;
  • commercial services
  • efficient transmutation of MA requesting

high fast flux intensity (Φ>0.75MeV = 1015 n.cm-2.s-1);

  • To demonstrate the ADS full concept by coupling the three

components (accelerator, spallation target and sub-critical reactor) at reasonable power level scalable to an industrial demonstrator;

  • To contribute to the demonstration of LBE technology and to

demonstrate the critical mode operation of a heavy liquid metal cooled reactor as an alternative technology to SFR

Decay heat removal system

  • Decay heat removal (DHR) through

secondary loops

  • 2 independent loops
  • redundancy (each loop has 100% capability

– min. sized for 3% continuous power)

  • passive operation (natural convection in

primary, secondary and tertiary loop)

  • Ultimate DHR through RVCS (natural

convection)

Safety improvements in XT-ADS

  • Unprotected events addressed by improvement of

natural convection

  • core hydraulic resistance reduced
  • level difference between core and PHX increased (1,2 m  2 m)
  • Boiling water HX instead of pressurized water HX to

mitigate tube rupture consequences

  • Ultimate DHR by RVCS system
