NUCLEAR REACTOR
A natural uranium-fucled reactor for the economic generation of electricity is given. The moderator structure inside the pressure vessels is formed with vertical fuel elements in channels symmetrically arranged on a regular lattice in groups. Control-rod channels are also arranged on a regular lattice each centered on one of the groups. A coolant circuit is connected with the pressure vessel above and below the moderator structure. Through the shielding around the pressure vessel and through the vessel extend control-rod channels with a control-rod living mechanism surmounting shielding plugs in access holes vertically above the channels. For fuel charging, chutes are introduced into the access holes. The vertical orientation has a number of advantages regarding support of the structure, arrangement of control rods (falling by gravity on failure or the mechanism), operating space, and shielding.
