The use of shell scripts as analysis tools

The typical safety analysis requires the coordinated execution of several computer codes and the associated data preparation. It was found that the process of ensuring consistency in the reactor physics models and simulations is prone to errors when data are entered in a non standard format and occasionally the transients require a large number of input data files and hence much manual labor. A new methodology for operating most of the reactor physics codes has been developed that addresses the problems of data consistency and reduced manual intervention. It relieves the analyst of many of the bookkeeping tasks when executing codes and permits greater attention to the physics of the modeled process. (author). 12 refs
