A Data processing program for transient sodium boiling and fuel failure propagation Tests (III); SISCO-A Computer code to analyze preservation data file

Onda, Kaoru*; Yamaguchi, Katsuhisa

A Data processing program SISC0, which has capabilities of checking the information of experimental data measurements with little labor and of analyzing the data conveniently using the checked information, was developed to conduct the accurate data processing of the test results of low-flow and low-heat-flux sodium boiling runs and the other runs obtained from the experiments carried out with the Transient Sodium Boiling and Fuel Failure Propagation Test facility. It is devised to use, to the full extent, the utility libraries of the Interactive Data Analysis System AXEL installed in the FACOM M-190/200 computer system at the O-arai Engineering Center. The data managements of the SISCO code are composed of two sub-systems : one is the BSISCO having functions of creating or updating the data bases with batch jobs to prepare for subsequent data analyses, and another is the ISISCO which is in charge of analyzing the data with TSS job under the support of AXEL system. In onder to respond to various kinds of requirements from analysts, seven option routines and thirteen command-macro procedures are available in respective sub-systems. The SISCO code supports following two types of data handling jobs : (i)data calibration job ; to fix and service the information of measurements, which is to be compiled into a preservation data file for the data reproduction, by the statistical analyses of calibration data and the displays of the results, (ii)data analysis job ; to obtain the graphic outputs of the multi-data analyses applied to the specified preservation data files. The data analysis of the SISCO code is so designed that one can use a certain command-macro as a stand-alone utility program appliciable to any test data comprehensively. It is possible to yield (a) summary traces of the test results containing the sub-frames of time series data plots of key signals in one figure, (b) multi-traces of the axial temperatures at required transient times, (c) analytical ...
