Review studies on the state of the art of separate effects and component behaviour of LWR cooling systems
The three papers contained in this volume are entitled: - "Contact condensation effects relevant to ECC-water injection into a cold leg main coolant pipe"; - "State of the art of two phase steam water flow in piping junctions", and - "Critical investigation and model development for countercurrent flow of gas and liquid in horizontal and vertical channels". Specific conclusions and recommendations are presented for each case. In order to develop more general models applicable to a wider range of situations, further experimental work needs to be done with emphasis on larger pipe diameters of test sections up to 30 mm and on increased system pressures. To obtain a better understanding of the physical phenomena, local parameters and their variations need to be measured more accurately by applying better and more advanced instrumentation.
