Rc The AST methodology requires the Identification of unfiltered leakage paths. Ihe VY reactor building N-2 penetrations on the reactor building South wall at elevation 258 ft (where grade is 252 ft) meet the selection criteria. The dispersion factors WQ from this location to the control moon fresh air intake (FA) location and the EAB are needed for the dose calculation.
