| 1 | Trace tritium recovery from the residue of liquid Li_(17)Pb_(83) alloy显示文摘The liquid Li17Pb83 alloy is a prominent breeder material for use in a fusion reactor.In the design of an effective tritium extraction system for the liquid lithium lead bubbler of the test blanket module of such a reactor,finding ways to strictly limit the losses of tritium and to minimize radioactive risks is very important.For this purpose,the isotope exchange process has been investigated as a means of trace tritium recovery from a model of the residue from Li17Pb83 alloy.The results indicate that the isotope exchange process is an effective means of tritium recovery from the residue of Li17Pb83 alloy,and the optimum composition of the exchange carrier gas is He + 0.1% D2.The exchange temperature and number of exchange steps are the main factors influencing the efficiency of tritium recovery from the residue.Trace tritium recovery efficiency increases with increasing exchange temperature and number of times of exchange.Tritium recovery efficiency can approach 80% when the residue is treated six times at 823 K.A gas-liquid two-phase contact model to describe the proceeding of tritium release from the liquid Li17Pb83 alloy has been derived on the basis of this experiment. | XIE Bo,YANG TongZai & WENG KuiPing Institute of Nuclear Physics and Chemistry,China Academy of Engineering Physics,Mianyang 621900,China | 2010 | Science China Chemistry2010，53，8： | 2 |

| 3 | Determination of solubility of uranium in liquid sodium显示文摘An experimental technique has been developed which overcomes the two major problems common to liquid metal solubility measurements,namely,maintaining the integrity of the samples during transfer of the liquid sodium from container to whatever device is used for analysis and detecting solute at very low concentration in liquid sodium.The solubility of uranium in liquid sodium has been measured over the temperature range 150~400℃,by equilibration and sampling technique,the solubility of uranium is approximately 0.00001%. | YANG Tongzai XING Pifeng YE Shiyou LONG Kaiming FU Zhonghua HE Yuhui JIANG Tao | 2008 | Nuclear Science and Techniques2008，19，2： | 0 |
