In order to focus on the ability of the TRAC code to predict critical discharge flowrates and water subcooling in a loss-of-coolant simulation, the TRAC-P1A version of the code has been applied to calculate the CANON experiments (Riegel and Marechal, 1977). The CANON experimental assembly consists of a horizontal 4.4 meter long pipe (10 cm I.D.) filled with pressurized (32 bar) subcooled water. Both ends of the pipe are closed off. The temperature of the water varied from 200 to 230/sup 0/C. The experiment consisted in suddenly opening one end of the pipe and recording the pressure as a function of time at several locations along the pipe and measuring the void fraction as a function of time at a location of 1.5 meters from the dead end. The void fraction measurements were done using a neutron scattering technique. A diaphragm is located at the broken end of the pipe with a variable diameter (30, 50, 70, 100mm) to slow down the ejection of water to about 5 seconds from 1 second (depending on the opening) in duration.
