Title: Fast neutron nuclear reactor - with intermediate height ports in the walls of the fissible fuel rod assembly shells
Inventor: ILJUNIN WLADIMIR GRIGORIEWITSC
IPC: G21C3/324
Filed: 1973-09-07
Abstract: The inner active zone of the reactor and the lateral and upper and lower frontal zones of breeder material around it are all made up of groups or bundles of fuel rods in jackets. The coolant inlet manifold is at the centre of the total height of the active fission zone and leads to ports in the walls of the shells of the assemblies of rods. These are both principal and supplementary rods and both types are symmetrically arranged above and below the central horizontal plane through the ports from the inlet manifold. The coolant flow splits into upwards and downwards streams through each of the fuel assemblies and is collected in upper and lower outlet manifolds above and below the front upper and front lower breeder zones respectively. For more uniform thermal transfer over the cross section of the core in plan view, the heights of the breeder assemblies at the upper front are staggered esp. at constant pitch from the edges inwards to the vertical axis where they are higher. Power of unit reactor is raised from typically 1,500 to 5,000 MW due to more uniform thermal transfer.

Title: Demister for dirty liq droplets - having agglomerating screen of chevron type construction followed by cyclone
Inventor: BRUNNER KUNZ DIPL ING
IPC: B01D45/12
Filed: 1974-01-26
Abstract: Separator for mists. formed from sticky or dirty liqs. consists of an agglomerating screen placed in the gas inlet before a cyclonic separator. The screen is formed from lamellae or plates bent in chevron fashion. The angle of the bands should be 30-270, pref. 90-180 degrees. The lamellae forming the screen is mounted parallel to the axis of the centrifugal separator in a concentric circle. The sides of the lamellae are formed as diffusers and are mounted directly in the entrance to the centrifugal separator. They are mounted by means of a base and lower plate which are clamped together with distance pieces or spacers in >=2 posns. The lamellae spacing is controlled by >=2 cam like protrusions on each lamella. Used esp. for dirty or sticky droplets which rapidly foul conventional demisters and block them, e.g. mesh or parking type. The screen serves to agglomerate fine droplets into larger ones which are then sepd. in the cyclone device. Since the operation of the lamellae is not affected by deposits, the device is not affected by fouling. It can be used on dust removal or washing devices. For very fine mists, link type lamellae can be used to cause the gas to turn through several large angles.
