We present details of our evaluation of the NNLO QCD corrections to B((B) over bar -> X-S gamma) in the heavy charm limit (m(c) >> m(b)/2). Results of this calculation have been essential for estimating O(alpha(2)(S)) effects in this branching ratio via interpolation in m(c). (C) 2010 Elsevier B.V. All rights reserved.
