[en] In view of the remarkable difference between ship reactor compartment (SRC) and nuclear power plant containment in space layout and structure size, the SRC pressure and temperature variations are more serious and relied on the dimension of SRC thermal-hydraulic model. Using RELAP5/MOD3.2 code, six SRC control volume models were established, including two-dimensional and three-dimensional models in space, and the variations of SRC pressure and temperature under supposed LOCA were analyzed. The characters of different models were studied and an optimized model was established. The result can be a reference in ship reactor SRC safety evaluation and thermal-hydraulics character analysis during LOCA. (authors)

[en] A supported liquid membrane with ionic liquid was used for the separation of toluene/cyclohexane. The interactions of ionic liquid with toluene and cyclohexane were calculated and experimentally studied by quantum chemical calculation and liquid-liquid extraction process. The results showed [BPy][BF_4] have stronger interaction with toluene than that with cyclohexane. The selectivity of SILM processes was larger than 10 at the temperature of 323 K and the flow rate of 13.5 mL·min"-"1 on both shell side and lumen side. Due to the higher viscosity of IL, SILM process had good long-term stability. As the effects of mass transfer driving force of SILM process, the flux and removal efficiency increased with increase of initial toluene concentration, while the selectivity decreased because of the competitive transport. Base on the resistance in-series model and experimental results, the mass transfer resistance was mainly lay liquid membrane phase. The influence of flow rates on both sides was slight. The higher temperature could enhance the mass transfer performance significantly. The removal efficiency increased from 28.2% to 45.1% with the increasing of operation temperature from 298 K to 323 K
