| 20150036779 | INTEGRAL MOLTEN SALT REACTOR - The present relates to the integration of the primary functional elements of graphite moderator and reactor vessel and/or primary heat exchangers and/or control rods into an integral molten salt nuclear reactor (IMSR). Once the design life of the IMSR is reached, for example, in the range of 3 to 10 years, it is disconnected, removed and replaced as a unit. The spent IMSR functions as the medium or long term storage of the radioactive graphite and/or heat exchangers and/or control rods and/or fuel salt contained in the vessel of the IMSR. The present also relates to a nuclear reactor that has a buffer salt surrounding the nuclear vessel. During normal operation of the nuclear reactor, the nuclear reactor operates at a temperature that is lower than the melting point of the buffer salt and the buffer salt acts as a thermal insulator. Upon loss of external cooling, the temperature of the nuclear reactor increases and melts the buffer salt, which can then transfer heat from the nuclear core to a cooled containment vessel. | 2015-02-05 |

| 20150036783 | DEVICE AND METHOD FOR GENERATING INPUT CONTROL SIGNALS OF A SERIALIZED COMPRESSED SCAN CIRCUIT - A device and a method for generating input control signals of a serialized compressed scan circuit are provided. A control signal generating device receives a test clock signal from a clock input port and a state enable signal from a state enable bus, and correspondingly generates a shift enable signal, a capture enable signal and a strobe signal. A clock gating device is coupled to the control signal generating device, and receives the shift enable signal, the capture enable signal and the strobe signal. When the shift enable signal is enabled, the clock gating device controls the test clock signal as a serialized scan clock signal. When the strobe signal or the capture enable signal is enabled, the clock gating device controls the test clock signal as a scan clock signal. | 2015-02-05 |
