Abstract
Ultrafiltration circuit for the primary cooling fluid of a pressurized-water nuclear reactor, comprising a first loop (27) taken off from the discharge branch (10) of the volumetric and chemical monitoring circuit (8) and a second loop (28) taken off from the charge branch (11) of the circuit (8). Each of the loops (27, 28) incorporates an ultrafilter (30, 50). The concentrate from the ultrafilter (30) located on the first loop (27) is cooled, depressurized and conveyed into the chemical monitoring circuit (8) via a pipe (38) downstream of the main cooling and depressurizing device (12, 13) of the circuit (8). The concentrate from the ultrafilter (50) of the loop (28) is conveyed into the chemical monitoring circuit (98) via a pipe (58) upstream of the device (12, 13).
