Abstract
Intrinsically safe emergency cooling device for a pressurized-water nuclear reactor, comprising an auxiliary circuit which feeds the steam generator and in which is arranged a condenser (10) receiving the steam from the generator and condensing it. The condensate is returned to the steam generator by means of gravity. The device also incorporates a passive adjustment means comprising an adjustable valve (21), a cylinder (23), the chamber of which communicates with the steam pipe (7) and contains a piston (33), and a coupling means (32) between the piston (33) and the shut-off element (30) of the valve (21). The feed rate of the steam generator and the cooling power of the condenser (10) can be regulated in this way.
