THERMAL IMPACT STUDIES FOR FRENCH COASTAL NUCLEAR SITES

Abstract

The paper presents the different stages of the environmental studies performed at the Laboratoire National d'Hydraulique concerning some of the French coastal nuclear power plants using a once - through cooling system, and the different means used, in function of the proper caracteri sties of the site, to come to an optimum inlet-outlet configuration leading to a minimum thermal impact and to a minimum recirculation of the heated waters at the intake. The paper particularly describes the original studies performed for the Flamanvilie power plant where a special computer controlled tank has been used.
