The Biblis activity atlas

Neutron intensity distribution in a vertical section of the 3D activation model of Biblis reactor B



  • PWR cross-section with reactor vessel highlighted
  • Neutron intensity distribution in a vertical section of the 3D activation model of Biblis reactor B
  • 3D core activation model (in plan)
  • One of the eight main coolant pipes at Biblis, each with a diameter greater than 1m.
  • Typical power distribution in an operating nuclear power plant: representation of a reactor core with its 193 fuel elements. Red areas generate greater thermal output and more neutrons than the areas marked in blue.
  • Typical power distribution in a single fuel assembly. Red areas generate greater thermal output and more neutrons than the areas marked in blue.
  • Presentation of the reactor neutron intensity distribution in a cut-out of the 3-D model of the upper reactor pressure vessel and the loop pipe: red equals higher neutron intensity and therefore higher activity.
