摘要： A passive emergency water system for cooling the atmosphere inside containment in a water-cooled nuclear reactor comprises an elevated in-containment water reservoir connected to an in-containment heat exchanger. The heat exchanger promotes natural convection of containment atmosphere and heat transfer. Heat from containment atmosphere is transferred to the reservoir by a convective return flowpath. The heat exchanger is preferably an elevated tube bank Baffle walls can be used inside containment to promote circulation of containment atmosphere. In one embodiment, the reservoir tank is closed with respect to containment atmosphere and is vented through the containment wall to the external atmosphere. In an alternative embodiment, the reservoir tank can be of a sufficient volume to absorb heat from containment as sensible heat without boiling.

摘要： An electron gun which is rugged, provides good thermal decoupling of the hode, permits precise alignment of the electrodes to be achieved easily and allows geometric changes to be carried out with ease is described. In the cathode assembly three set screws and a split ring of insulating material are used to secure the cathode. Alignment is achieved by suitably adjusting the set screws and because contact can be limited to the three set screws thermal coupling is reduced. Similarly a Whenelt electrode is secured and aligned by a further group of set screws. Finally, the anode is secured to replaceable stand-offs by means of screw passing through oversized holes in an anode plate. The oversized holes permit easy alignment and the use of stand-offs permits the spacing between anode and cathode to be changed as desired by replacing the stand-offs.

摘要： A method of generating a computed tomographic image of a region-of-interest of a sample is described in which only the region-of-interest need be scanned, i.e. it is not necessary to scan the entire sample. Reference data for the region-of-interest of a complete reference object that is a relatively good match to the sample outside the region-of-interest and has a known attentuation distribution inside the region-of-interest is first obtained. This can be done by scanning only the region-of-interest of an actual complete reference object or by constructing a digital image of the reference object and mathematically scanning only the region-of-interest of the image. Then the region-of-interest of the sample is scanned to obtain sample data from which the reference data is subtracted. A differential image is reconstructed from the differential data thus obtained. The method allows the use of equipment which is simpler, more compact and less costly than conventional CT equipment.

摘要： A method for assaying a wall of a pressure tube for a nuclear reactor is disclosed. The wall has a matrix material and deuterium nuclei in the matrix material. The method includes: (a) transmitting gamma rays into the matrix material to induce photodisintegration of at least some of the deuterium nuclei, whereby reaction particles of the nuclei are emitted from the wall; (b) detecting at least some of the reaction particles emitted in step (a) using a particle detector; and (c) generating particle signals in response to detecting the particles in step (b).
