Units courses prerequisite and corequisite

Prerequisite or corequisite units are presented within each program

Learning unit contents

  • Reactor heat generation
  • Transport equations (single-phase & two-phase flow)
  • Thermal analysis of fuel elements
  • (Single-phase fluid mechanics and heat transfer)-usually already known
  • Two-phase flow dynamics
  • Two-phase heat transfer
  • Single heated channel; steady state analysis
  • Single heated channel; transient analysis
  • Flow loops
  • Utilisation of established codes.

Learning outcomes of the learning unit

  • To be familiarised with various reactor types and their main design and operational
    characteristics
  • To learn how to estimate the volumetric heat generation rate in fission reactor cores under
    normal operation and shutdown conditions
  • To learn how to analyse the thermal performance of nuclear fuel elements
  • To learn the basic fluid mechanics of single phase reactor cooling systems
  • To learn to calculate pressure drop in reactor systems, including tube bundles, and spacer
    grids
  • To learn to analyse the heat transfer characteristics of single phase reactor cooling systems
  • To learn the basic fluid mechanics of two-phase systems, including flow regime maps, void-quality relations, pressure drop, and critical flow
  • To learn the fundamentals of boiling heat transfer, and its implications for reactor design
  • To learn the fundamentals of core thermal design, with attention to design uncertainty
    analysis and hot channel factors.
