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.
