Section: abstract

The invention relates to an underwater electricity generation module provided with a base. The electricity generation module is of the type that comprises an elongate cylindrical casing (12) incorporating an electricity generation unit (25a, 25b) comprising a nuclear boiler (28, 29) associated with electricity generation means (30, 31) connected to an external electricity distribution post (7) by means of electric cables (6). The lower portion of the casing (12) is provided with a base (14) that rests on the bed of the water body and anchoring means (15) for anchoring the module (1) to the bed. The invention is characterised in that the base (14) is essentially in the form of a sledge which extends from one end of the casing (12) to the other and the ends (50, 51) of which are curved in the form of a spatula at each end of the casing (12), said base including zones for absorbing variations in the length of the casing (12), linked to the variation in the pressure applied thereto when submerged or surfaced.
