A shielding module for a radioactive waste container (C) comprising a perimeter wall (1) and a closing lid (2), which define a cavity (3) suitable for housing the container (C), and a number of metal elements (4) attached along the perimeter wall (1) and protruding into said cavity (3), said metal elements (4) forming means for limiting lateral movement, for centring and for dampening impacts against the side wall of the container (C) with respect to the shielding module (10), in the event of potential external impacts or the sideways fall of the assembly formed by the container (C) and the shielding module (10).
A radioactive waste container comprising: a radionuclide containment barrier (1) delimiting a housing (16) for radioactive waste and comprising a first ferrule (11), a bottom (12), an upper flange (13), and a lid (14) fixed by bolts (15) to said upper flange (13); a shield (2) against gamma radiation, arranged externally with respect to the containment barrier (1) and comprising a second ferrule (21) with external fins (22) defining gaps between them, a lower closing flange (23), an outer lid (24) provided with bolts (25) for fixing to the upper flange (13) of the containment barrier (1), and an outer bottom (26) fixed to the lower closing flange (23); and a neutron shielding material (3) arranged in the gaps defined between the fins (22) of the second ferrule.
A radioactive waste container, suitable for housing a canister or rack (C) containing the waste constituting a source of radioactive emission; and comprising: an inner containment barrier (1) against photon radiation, delimiting a housing for the canister or rack (C) containing the radioactive waste to be stored and comprising: an inner cylindrical steel ferrule (11), a base (12) and a lid (13); an outer containment barrier (2) against photon radiation, forming the outer surface of the container (10) and comprising: an outer cylindrical steel ferrule (21), a base (22) and a lid (23) and, an intermediate concrete layer (3) arranged between said inner (11) and outer (21) ferrules and forming a shield against neutron radiation.
Disclosed is a method comprising: placing a central steel ferrule (2) on a central reinforcement mesh (1); installing around the central ferrule (2) a central assembly (3) and prefabricated pieces (4, 5) comprising a concrete beam (4) and a steel strut (5); assembling (61) sections between the bases (43) of the beams (4), and filling in (62) the central assembly (3); installing formwork (71, 72, 73) around the central assembly (3), the infill (62) and the outer perimeter; and obtaining, by means of simultaneous concreting, a monolithic concrete foundation (10) in which the ends of the struts are embedded, thus forming the ribbed foundation.
The invention relates to a solar panel securing system comprising: a pair of upper cables (1) and a pair of lower cables (6), arranged longitudinally and fasten by opposite ends to support posts (2); transverse cables (11) mounted on the upper cables (1) and which, by means of vertical suspenders (5), secure support means (4) for supporting parallel rows (31) of solar panels (3) disposed horizontally, in a transverse direction, below the upper cables. Longitudinally, below the lower cables (6), the system comprises braced lateral arches (7) and oblique stays (8) that fasten the sides of the support means (4) of the solar panels (3) to the corresponding lateral arc (7).
F24S 25/50 - Arrangement of stationary mountings or supports for solar heat collector modules comprising elongate non-rigid elements, e.g. straps, wires or ropes
H02S 20/30 - Supporting structures being movable or adjustable, e.g. for angle adjustment
The present invention relates to a radioactive gas containment system for nuclear waste containers that comprises: a first fastening flange (1) for fastening the system to a nuclear waste container (C); bolts (11) for horizontally tightening the first fastening flange (1) against the container (C); a covering lid (2) for covering the top of the container (C); a containment gasket (3) arranged between the lid (2) and the first fastening flange (1); bolts (4) for vertically tightening the lid (2) against the first fastening flange (1) and the containment gasket (3) arranged between the lid (2) and said first fastening flange (1); and a pressurising device (5) for pressurising the space between the container (C) and the lid (2) and for controlling radioactive gases.
