dc.description.abstractExperimental results from the Canadian forced convection loop FLARE (D'Arcy 1968) have been used to assess the value of the TOSCLE computer code (Spinks 1971) for calculating flow stability characteristics of pressure tube reactor systems. Good agreement has been found between TOSCLE calculations and the FLARE results for high values of subcooling. TOSCLE indicated a crucial boiling length as supposed by Shotkin (1967) . However, this does not appear to be consistent with the FLARE experimental data and large discrepancies occur at low subcoolings. The experimental results showed an increased scatter in the low subcooling region. A possible cause for this and for the discrepancy with calculated results at low subcooling are suggested. The sensitivity of TOSCLE results to various input parameters was examined. Most parameter variations were found to have only a minor effect on the results. Further experimental work in conjunction with detailed theoretical analysis is essential, particularly in the area of low subcooling which is of great importance in power reactor design.en_AU
