ULTRAFILTRATION CIRCUIT FOR THE PRIMARY COOLING FLUID OF A PRESSURIZED-WATER NUCLEAR REACTOR

摘要

Ultrafiltration circuit for the primary cooling fluid of a pressurised-water nuclear reactor, which comprises a first loop taken off from the discharge branch of the volumetric and chemical monitoring circuit and a second loop taken off from the charge branch of the circuit. Each of the loops incorporates an ultrafilter. The concentrate from the ultrafilter located on the loop is cooled, depressurised and conveyed into the circuit via a pipe downstream of the main cooling and depressurising means of the circuit. The concentrate from the ultrafilter of the loop is conveyed into the circuit via a pipe upstream of the means.
