  • Patent number: 11049624
    Abstract: A liquid metal-cooled nuclear reactor includes, within a reactor pressure vessel, a primary electromagnetic pump (EMP) circulating liquid metal coolant through the reactor core and a backflow EMP. The nuclear reactor may be configured to at least partially mitigate liquid metal coolant backflow in response to a primary EMP failure. The backflow EMP is coupled in series with the primary EMP within the reactor pressure vessel. The backflow EMP may be selectively activated in response to failure of the primary EMP to mitigate liquid metal backflow through the primary EMP. The primary EMP and backflow EMP may receive power from separate power sources. Multiple backflow EMPs may be coupled in parallel to the primary EMP via parallel liquid metal coolant lines. A nuclear reactor may include multiple primary EMPs and multiple sets of backflow EMPs, where each separate set of backflow EMPs is coupled to a separate primary EMP.

  • Patent number: 6146948
    Abstract: A method for forming a gate dielectric having different thickness begins by providing a substrate (12). A sacrificial oxide (14) is formed overlying the substrate (12). A first portion (11) of the sacrificial oxide (14) is exposed to a carbon-containing plasma environment (20). This carbon-containing plasma environment (20) forms a carbon-containing layer (24) within the region (11). After forming this region (24), a wet etch chemistry (22) is used to remove remaining portions of the sacrificial oxide (14) without forming a layer (24) in the region (13). Furnace oxidation is then used to form regions (26a) and (26b) wherein the growth of region (26a) has been retarded by the presence of the region (24). Therefore, the regions (26a) and (26b) are differing in thickness and can be used to make different transistors having different current gains.
