Title: Computing the Time-Averaged Nuclide Inventory Using the Chebyshev Rational Approximation Method.
Authors: Whitmer, Charles1 (AUTHOR) chuckwh@terrapower.com, Zimmerman, George2 (AUTHOR)

Subject Terms: *Chebyshev approximation, *Fuel burnup (Nuclear engineering), *Isotopes
Abstract: The Chebyshev Rational Approximation Method (CRAM) algorithm has become the method of choice for modern nuclear depletion calculations. A simple modification of the CRAM yields not only depleted nuclide amounts but also time-averaged nuclide amounts, with little additional calculation cost. [ABSTRACT FROM AUTHOR]
