MASS FLOWRATES THROUGH THE VENT LINES DURING AIR TESTS OF THE 1/5-SCALE MARK I BWR PRESSURE SUPPRESSION SYSTEM

摘要

Mass flowrates per downcomer show that the three vent lines connecting the drywell to the toroidal wetwell test sections are matched within 10% on 19 of 23 applicable air tests. Vent line flow coefficients determined for the first 0.3 seconds after the start of drywell pressurization are within 20% of calculated values.
