Nuclear power station comprising at least one high temperature reactor

Nuclear power station comprising:

• a plurality of high temperature reactors (2), each comprising a core (4) in which a plurality of fuel elements (5) are arranged;
• for each reactor (2), a dedicated storage installation (14, 16, 18, 20, 22) for the fuel elements (5) for said reactor (2);
• means (32) for transferring the fuel elements (5) between the core (4) and the storage installation (14, 16, 18, 20, 22);
• wherein the transfer means (32) comprise:
• a tunnel (34), of which a first portion (36) is situated near the core (4) and a second portion (38) is situated in or near the storage installation (14, 16, 18, 20, 22);
• first transfer means (48, 58) suitable for transferring at least one fuel element (5) between the core (4) and the first portion (36);
• second transfer means (78) suitable for transferring at least one fuel element (5) between the second portion and the storage installation (14, 16, 18, 20, 22);
• means (66) for transferring at least one fuel element (5) along the tunnel (34) between the first and second portions (36, 38);
• and
• means (86, 88) for moving the tunnel (34) between a plurality of service positions each corresponding to one of the reactors (2), the first portion (36) of the tunnel (34) being situated in each service position near the core of the corresponding reactor and the second portion (38) of the tunnel (34) being situated in or near the dedicated storage installation (14, 16, 18, 20) for said reactor (2).
