摘要： A high-temperature containment-isolation system for transferring heat from a nuclear reactor containment to a high-pressure heat exchanger is presented. The system uses a high-temperature, low-volatility liquid coolant such as a molten salt or a liquid metal, where the coolant flow path provides liquid free surfaces a short distance from the containment penetrations for the reactor hot-leg and the cold-leg, where these liquid free surfaces have a cover gas maintained at a nearly constant pressure and thus prevent high-pressures from being transmitted into the reactor containment, and where the reactor vessel is suspended within a reactor cavity with a plurality of refractory insulator blocks disposed between an actively cooled inner cavity liner and the reactor vessel.

摘要： An accelerator-driven sub-critical reactor providing: 1) a significantly more efficient Thorium-cycle system, in one configuration, 2) a more energy-productive nuclear waste reduction system, 3) accelerator driven systems for other fertile-fission candidate elements, and 4) which may be applied to fusion systems (substituting the fission unit in the proposed system class and category) in a way that may lower the break-even point for such systems and thus make the advent of practical fusion sooner than otherwise possible. 5) In addition and importantly, an optical-power processing and distribution is also enabled by the proposed, providing both optical power as base power for telecom, process energy for industrial uses, and lighting and other wavelengths for consumer and general business use.

摘要： The device (15) for joining together a first plate (7) and a second plate (8)of the baffle assembly, which are located substantially at right angles, includes a screw (16) engaged in a housing consisting of an opening (18) passing through the first plate (7), and of a tapped blind opening (20) in the second plate (8). At least one opening (21) places an annular space (18b) around the shank (16b) of the screw in communication with the entry part (18a) of the opening (18) passing through the first plate (7), in order to deconfine the screw (16). The opening (21) may be a radial opening passing through a cup (17) against which the screw head (16a) comes to bear or an opening machined in the first plate (7) against a shoulder (18c) of the screw housing and the part (18b) of the opening for passing through the first plate (7) in which the shank (16b) of the screw (16) is engaged.

摘要： The heat shield according to the invention makes it possible to protect a structure from a very high thermal flux. It is mainly constituted by tiles (2) fixed to a support structure (4) by means of a spring (8) fixed in translation with respect to a tile (2) and on which bears a locking arm (10). The latter can be fixed to the support structure (4) by means of locking screws (30), which are accessible from the outside through locking orifices (12) in the tile (2). The compression of the spring (8) allows locking to take place and also a satisfactory heat exchange from the tile (2) to the support structure (4), which can be cooled by cooling medium flow ducts (14).

摘要： A bolt insert 24 with special bolt 50 provides a fastening method to secure hard metal nuclear reactor parts 12, 14, 16 provided with aligned square EDM produced openings 18, 20, 22. The insert is an elongated square internally threaded member with slots 34 defining flexing fingers 36. Fingers 36 have work engaging shoulders 42. Stop means tabs 28 at the bolt head end prevent overinsertion of the square insert 24 during the operation of pushing it into aligned square holes 18, 20, 22. Internal threads 32 of insert 24 mate with bolt threads 60 during torquing on bolt head 52 to advance bolt 50, which has tapered end 56 and pilot portion 58, to cam fingers 36 into holding position. Couterbores 30 receive stop means tabs 28 such that bolt head 52 does not bottom on insert 24. The method of producing fastening 10 removes the need for accurate threading operations on irradiated parts in the remote field.

摘要： A size-adjustable construction element involves use of channel spacers to maintain spaced parallel relationship and positive physical contact between adjacent panel members. A preferred embodiment of the invention comprises multilayered mirror insulation having an adjustment section to permit use of a standard size component to fit nonstandard dimensions and further includes channel spacers that effectively reduce convection between adjacent layers, provide positive structural support, provide a bearing surface for ease of adjustment and maintain the parallel space relationship between adjacent sheets.

摘要： A nuclear reactor having a remotely removeable and replaceable thermal and/or radiation insulating shield for the head. This shield is formed of interlocked integrated shielding units of thermal insulating material. Each unit has a vertical member and a horizontal member. Each unit has a lifting-and-lowering rod on its top and it may be raised vertically by a remotely operable clamp engaging the head. The interlocking surfaces of adjacent units are so formed that when any unit is raised or lowered vertically its interlocking surface readily slides along the interlocking surfaces of the units adjacent to it with which it is interlocked.

摘要： The vault of a liquid metal cooled nuclear reactor is lined with thermal insulation. The insulation is in two layers, a first layer cladding the vault surface is of solid ceramic material while a second layer cladding the first layer is of fibrous or metallic material. In the event of a breach of the vessel leakage of liquid metal is absorbed by the second layer providing a conduction path to the first layer thereby enhancing heat loss to the concrete of the vault and maintaining the internal temperature at a safe limit.
