Abstract

Accurate calculation of fluence to reactor structures involves integration of exposure over time taking into account changes in operating conditions and also estimation of the uncertainty in the calculation process. This paper reports on recent improvements we have made in calculation techniques and also on validation of those techniques by benchmarking against measurements in operating boiling water reactors (BWRs). Results and discussion of calculations in regions that fall outside the reactor beltline and thus require 3-D calculations to produce accurate results are presented.
