Burnup rate and Consumption rate

  1. Dec 12, 2006 #1
    Hey ,

    1-What is exactly the difference between the Burnup rate and Consumption rate??

    2-Why do most authorities usually use the term of Burnup rate while the consumption rate it seems to be more general ?!

    What does one mean by consumption rate?

    Burnup (in MWd/kgU or GWd/tU) is the energy per unit mass of fuel. Most utilities and manufacturers/suppliers of nuclear fuel use burnup as a basic unit. Some European organizations use burnup in terms of GWd/tUO2. Many fuel properties and fuel performance have been correlated with burnup. Some metal (cladding, guide tube, . . . ) behavior are correlated to fluence (fast flux integrated over time), which is related to dislocation density or dpa.
