AN INTEGRAL RESPONSE SCALING METHOD FOR REDUCED-HEIGHT TEST FACILITIES AND ITS VALIDATION USING RELAP5 FOR LOSS OF RHR DURING MIDLOOP OPERATION

摘要

An integral response scaling method for reduced- height test facilities is described and validated for the local and the integral phenomena using the RELAP5 THERMAL-HYDRAULIC CODE. In the present schematic scal- Ing methodology, the scaling laws are generated from Four scaling analyses: three-dimensional differential Equation-based scaling analysis, one-dimensional differ- Ential equation-based scaling analysis, component- Based scaling analysis, and overall integral scaling Analysis.
