[en] The TIPSY program processes 3-D power and depletion distributions which represent results from PDQ08, 3-D explicit or Kaplan and ZIP synthesis problems. Alternately, PDQ08 transverse planar files containing power and depletion data are input together with axial power peaking factors and fuel fractions. The transverse planar and axial data are combined to form 3-D distributions. The products from the TIPSY program are parameters characterizing the power peaking factor and fission density distributions of every fuel element in the PDQ08 solution region, detailed segment peaking factor and fission density distributions for a selected set of coolant channels, and estimates of the critical heat flux and peak central temperature performance. 13 figures, 9 tables
