Abstract
A nuclear reactor installation includes a pressurized-water reactor having a main coolant pipe line loop provided with a pressurizer. The steam space of the pressurizer is connected to a tank containing a concentrated solution of boric acid and which is connected with the loop via a normally-closed valve means which opens when the loop pressure reduces below normal, so that the steam pressure in the pressurizer, drives the solution from the tank into the loop and thus into the reactor where the concentrated boric acid solution provides equalization for the increase in the reactor's core reactivity which takes place when the coolant temperature drops.
