摘要： The present invention relates to an apparatus for protecting a containment building from a molten core generated from a nuclear reactor and, more specifically, to an insulator provided outside a reactor pressure vessel. A nuclear reactor insulator can comprise: an insulating body which is positioned at a predetermined distance away from the lateral side of a reactor pressure vessel and encircles the lateral side of the reactor pressure vessel, and of which the lower part is tapered; and a soluble plug which is provided on the bottom side of the insulating body and is for storing a molten core generated from the reactor pressure vessel, wherein the molten core discharged from the lateral side of the reactor pressure vessel can be guided and discharged downward. The present invention can prevent thermal damage to a containment building due to damage in the lateral side of the reactor pressure vessel, and enables installation of a core catcher of which the cross-sectional area has been reduced by means of guiding the molten core downward and increasing the predictability of the storage thereof. Moreover, the present invention enables reduction of a heat load in the core catcher by means of retarding the time of the molten core reaching to the core catcher and reduces the risk of a steam explosion of the containment building, due to multiple discharges, by means of reducing the number of molten core discharges from the reactor pressure vessel to a reactor cavity.

摘要： An embodiment of a nuclear power plant has: a reactor vessel (11) containing a core (10); a reactor containment vessel (12) containing the reactor vessel (12); and a radiation heat reflecting member (30) disposed at a portion below the reactor vessel (11) inside the reactor containment vessel (12). The radiation heat reflecting member (30) may block radiation heat, which is emitted toward a side wall surface (23) of the reactor containment vessel (12) from the core (31) that has been put in a molten state by an accident and flowed downward from the reactor vessel (11) to be accumulated at a lower portion (19) of the reactor containment vessel (12). The radiation heat reflecting member (47) may block radiation heat, which is emitted toward a supporting structure (42) supporting devices (44) disposed inside the reactor containment vessel (12).

摘要： A method for limiting movement of a thermal shield (13) of a nuclear reactor (10), and a thermal shield displacement limiter (19) therefor, is provided where at least four and preferably six or more key-way inserts (21) are positioned in pockets (20) machined in the upper portion (22) of a thermal shield (13), and bolted (24) and doweled (28) to the thermal shield (13). Each key-way insert (21) is engaged by a limiter key (29) that is bolted (34) and doweled (37) to the core barrel (12) to tangentially restrain movement of the thermal shield (13) relative to the core barrel (12), while allowing a radial and axial movement of the thermal shield (13) relative to the core barrel (12). Preferably, lock pins (39) extend diametrically through the bolts (24, 34) and dowel pins (28, 37) and engage the key-way insert (21) and limiter key (29), respectively, to lock the bolts (24, 34) and dowels (28, 37) in position, and the engaging surfaces between the key-way inserts (21) and the limiter keys (29) are wear hardened.

摘要： Dans un réacteur nucléaire à neutrons rapides, refroidi par un métal liquide, les viroles libres émergeantes des structures internes (28) sont équipées, du côté du collecteur chaud (32), de bacs (36) remplis de métal liquide. Le fond de ces bacs est à un niveau inférieur au niveau minimum (N min ) du métal liquide dans le collecteur chaud, alors qu'au moins un passage (40a) permet la libre communication entre les bacs (36) et le collecteur chaud lorsque le niveau du métal liquide dans ce dernier atteint une valeur maximum (N max ) correspond au régime nominal du réacteur. Les contraintes thermiques dans les viroles émergeantes des structures internes (28) sont ainsi très atténuées.

摘要： In a liquid metal cooled fast neutron nuclear reactor plant, surfaces (12) which are immersed in the flowing liquid metal and are vulnerable to liquid metal temperature fluctuations are provided with fins (20) defining cavities (22) for at least temporarily trapping the liquid metal to produce a thin layer of the liquid metal on the surface and thereby attenuate the effect of temperature fluctuations occurring in the liquid metal flow.
