Fundamental

Nuclear Waste Heat Generation

Q_waste = Σ P_i (1 - e^{-λ_i t})

Fundamental

Fuel Inventory Calculator

I = V × ρ × (1 - porosity) × enrichment

Fundamental

Nuclear Fuel Efficiency

NFE = (energy produced) / (energy in fuel)

Fundamental

Uranium Consumption Rate

UCR = P / (η × F), where P = thermal power, F = energy per gram

Fundamental

Fuel Pellet Density

ρ = mass / (π r² h)

Fundamental

Spent Fuel Activity

A_sf = Σ A_i e^{-λ_i t}

Fundamental

Fuel Cycle Cost Calculator

FCC = (enrichment cost + fabrication cost + reprocessing cost + disposal cost) / (electricity generated)

Fundamental

Fuel Residence Time

t_res = (fuel mass) / (burnup rate)

Fundamental

Fuel Utilization Factor

U = (burnup × initial HM) / (initial fissile mass)
