Popis:	This report consists of two parts. In Part I physically based calculational models are proposed for predicting (a) conditions for stratification due to HPI in a circulating reactor loop (stratification model) and (b) cooldown transients due to HPI in a stagnated primary reactor fluid (thermal mixing model). The integral aspects of these models are confirmed by comparison to the CREARE 1/5-scale data. In Part II the thermal mixing model is assessed in an integral as well as in a local sense by comparison to the first round of data from Purdue's 1/2-scale facility. These data are the only available large-scale data at this time and they are an important complement to CREARE's 1/5-scale results in constructing a basis for scale-up to reactor conditions. Facility construction, instrumentation, data reduction techniques and detailed experimental results are also included in Part II.
