Experiment data report for 1-1/2-loop semiscale system isothermal tests 1008 and 1010

Abstract

Recorded test data are presented for Tests 1008 and 1010 of the isothermal portion of the Semiscale Blowdown and Emergency Core Cooling (ECC) ,Project. These data represent the results of the first isothermal tests utilizing an enlarged downcomer gap (1.0 inch) in the pressure vessel to investigate general system hydraulic response both with and without simulated ECC injection. The data, presented in the form of composite graphs in engineering units, have been analyzed only t o the extent necessary to assure that they are reasonable and correct. The intent of this report is to make available the uninterpreted data from Tests 1008 and 1010 for use by others and for support of subsequent interpretive reports and analysis. ii.

Error analysis for 1-1/2-loop semiscale system isothermal test data

“…The following are the error componentsidentified as affecting the general data due to the data acquisition and processing: (l) Electronic pickup noise ±0.1% of full scale (2) General electronic system ±0.05% of full scale (3) Calibration and correction ±0.9% of full scale…”
