In order to compensate the influences of density variations in the water- steam mixture in the core of a boiling water reactor mounted on a ship, these variations being caused by vertical accelerations, the flow of the liquid through the reactor is regulated. The compensating device controls the opening of a by- pass of the pump provided to make the liquid circulate through the core, so that this opening is increased in the case of an acceleration in an upward direction and vice versa, with the production of an alteration (a reduction or an increase, respectively) in the circulation. Preferably a regulating mass is supported by elastic means so as to be movable in a vertical direction, this mass being connected with an organ controlling the opening of the by-pass. Suitably a second mass with an elastic support ensures a lead of phase of the circulation relative to the phase of acceleration by controlling the opening of the by-pass by means of a second control device connected with this second mass. For this purpose the movement of the second mass is damped by an adjustable device. (NPO)
