| Abstract: | Three methods, using different thermal transients, are proposed to measure the heat loss of a thermohydraulic facility. They can he used for loop-type facilities, with circulation pumps, and for vessel-type facilities, with fluid at saturation. The analysis of uncertainties of the measurement results can help to design a heat loss experiment for a specific application. Examples are presented of heat loss measurements at the LOBI-MOD2 facility, which is an integral system thermohydraulic test facility for safety investigations of pressurized water reactor (PWR) nuclear power plants. |
