Nuclear Fuel Burnup & Depletion Calculator
Nuclear fuel cycle engineering: Calculate fuel burnup ($B$ in $\text{GWd/tU}$ and $\text{MWd/kgHM}$), Fissions per Initial Metal Atom ($\text{FIMA}\%$), U-235 isotopic consumption, and fission product mass.
Reactor Thermal Power & Core Loading
Standard 4-loop PWR ~3400 MWth (~1100 MWe)
Metric tonnes of heavy metal (tU)
Fuel Enrichment & Operating Time
Natural uranium = 0.72%; LEU = 3–5%
Equivalent Full Power Days (3-cycle assembly ~1200 days)
Standard total recoverable energy: ~200 MeV
