Design and development of a steam generator emergency feedwater passive system for existing and future PWR's using advanced steam injectors

Objective

The present proposal deals with the utilisation of steams injectors (or steam jet pumps) in Pressurised Water Reactors (PWR's). A steam injector is a passive injection device using pressurised steam to suck outer cold water. The first steam injector was patented during the 19th century and then widely used in steam engines. Today, no utilisation of steam injectors is foreseen in nuclear reactors despite its working principle is well adapted to plants having so huge quantity of steam available. In PWR's, the most promising application appears to be the Steam Generator Emergency Feedwater System. It is proposed to make the necessary progresses in steam injector thermal hydraulics in order to reach a really optimised design. The experimental data base will also be used to develop and to qualify a numerical modelling required to make the system evaluation.
