Abstract

The exact specification of the dimensions and material composition of any benchmark system are a necessary condition for any validation calculation or cross section adjustment attempt. Experience has shown that currently available compilations of critical assemblies specifications sometimes have a few major shortcomings. These include: (a) Lack of some information on the dimensions or material composition of an assembly; (b) Seemingly redundant data that indicate inconsistencies in the description; (c) Incomplete description of `corrections' applied to experimental data in order to compensate for experimental difficulties. CRISY, a critical assemblies documentation system, reflects the experience of generating input data for reactivity calculations of critical assemblies. CRISY consists of two parts: (a) An electronic spreadsheet that has entries for the data given in the literature, entries for the necessary input for transport codes and the linking formulae used. (b) Documentation of the data available for each critical assembly.
