Phenomenological uncertainties in the suspended radionuclide concentrations in containment during severe LWR accidents

Creators

Description

CONTAIN, a code for integrated analysis of containment phenomenologies in complex LWR severe accident sequences, is being applied in a program for evaluating the uncertainties in USNRC-sponsored efforts to better define LWR accident source terms. The Surry TMLB' sequence was studied in detail. Aerosol agglomeration uncertainties were found to contribute about an order of magnitude to the overall uncertainty in suspended radionuclides (almost entirely). Containment compartmentalization effects contribute substantial uncertainties in either direction, while effects due to complex multicomponent aerosol compositions contribute lesser, but still potentially significant uncertainties (mostly downward). Incomplete treatment of radionuclide decay chains can contribute factor-of-two upward uncertainties
