Title (EN) PLATE TYPE NUCLEAR MICRO REACTOR
(FR) MICRO-RÉACTEUR NUCLÉAIRE DE TYPE PLAQUE
Abstract:
(EN) This invention provides a nuclear reactor design that can enable automated or semi-automated manufacturing of a small reactor in a mechanized factory. This is possible by following a layered approach to combine simple "plate" geometries with the use of diffusion bonding and computer aided manufacturing techniques that integrate all the fuel, axial reflectors, axial gamma and neutron shields, fuel gas plenum, heat removal mechanism, primary heat exchangers and moderator all in one block or component. The final assembled block has no welds and limits or eliminates manual operations. This design has the potential to reduce the fabrication time of an entire nuclear reactor to just a few days.
(FR) La présente invention concerne une conception de réacteur nucléaire qui peut permettre la fabrication automatisée ou semi-automatisée d'un petit réacteur dans une usine mécanisée. Ceci est possible en suivant une approche en couches pour combiner des géométries de « plaque » simples à l'aide de techniques de soudage par diffusion et de fabrication assistée par ordinateur qui intègrent tous les combustibles, des réflecteurs axiaux, des protections axiales gamma et neutroniques, un plénum de gaz combustible, un mécanisme d'élimination de chaleur, des échangeurs thermiques primaires et un modérateur tous dans un bloc ou un élément. Le bloc assemblé final n'a pas de soudures et limite ou élimine des opérations manuelles. Cette conception a le potentiel de réduire le temps de fabrication d'un réacteur nucléaire entier à seulement quelques jours.
