THOR - Thermal-Hydraulics Open-access Research

THOR - Schematic Loop Design

Water Thermal-Hydraulics (T/H) loop for open-access R&D at M-SParc

  • Designed, built and operated by Nuclear Futures Bangor RDTH – and collaboration partners
  • Building local capability & competence in advance of a National T/H Facility (NTHF)
  • Platform for instrumentation, digital infrastructure and rig development
  • Step-wise approach is key
  • Initial low-pressure configuration, later to be increased to 16 bar

First, generic procurement phase completed in April 2020

  • Variable speed pump; secondary heat exchanger
  • Flow meter; high speed camera and supporting stereo vision camera systems
  • Data acquisition systems; computation system; controls and instrumentation infrastructure, software and hardware
Detailed design phase entry May 2020
  • Proceeding from major component layout to loop simulation, dimensioning and component design
