摘要： A system for attenuating seismic forces includes a reactor pressure vessel containing nuclear fuel and a containment vessel that houses the reactor pressure vessel. Both the reactor pressure vessel and the containment vessel include a bottom head. Additionally, the system includes a base support to contact a support surface on which the containment vessel is positioned in a substantially vertical orientation. An attenuation device is located between the bottom head of the reactor pressure vessel and the bottom head of the containment vessel. Seismic forces that travel from the base support to the reactor pressure vessel via the containment vessel are attenuated by the attenuation device in a direction that is substantially lateral to the vertical orientation of the containment vessel.

摘要： An annulus spacer for a fuel channel assembly of a nuclear reactor, and method of manufacturing an annulus spacer. The fuel channel assembly includes a calandria tube and a pressure tube positioned at least partially within the calandria tube. The annulus spacer includes a garter spring configured to surround a portion of the pressure tube to maintain a gap between the calandria tube and the pressure tube. A girdle wire is positioned substantially within the garter spring and configured to form a loop around the pressure tube. The girdle wire includes a first segment and a second segment that overlaps the first segment to form an overlap, the overlap extending between approximately 45 degrees and approximately 135 degrees to reduce the possibility of girdle wire twisting.

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.
