Analysis of uncertainty in decay heat for I2S-LWR
Lynch, Matthew Emile

Depletion studies were performed on an I2S-LWR quarter assembly lattice, and decay heat curves were generated considering sensitivity to enrichment, burnup, power, power oscillations, and fuel management strategy. Overall, I2S-LWR fuel has greater decay heat than a standard PWR, both in absolute and relative terms. Covariance of burnup and power is found to be nonzero.
