在深入研究电解富集法、气液相催化交换法、气相色谱氢同位素分离技术和氢氧复合技术的基础上，2004年年中在中国工程物理研究院建成了处理10t/a氚水的CeCe-GC原型系统。成功地完成了从含氚水中回收氚的示范实验和从含氚水中回收氚的模拟运行。在该系统中，CeCe的总浓缩系数约为4，氚的分离系数约为10，运行时间为240h。50m~3/d的GC系统在6h内成功地从10m~3氚氢气中回收了90%的氢，该部分的氚浓度被耗尽了1000多倍。该实验系统为进一步的工程实践打下了坚实的基础。
Based on the thorough study of electrolysis enrichment, gas–liquid phase catalytic exchange, gas chromatography for hydrogen isotope separation, and hydrogen–oxygen recombination technologies, a CECE–GC prototype system with disposal capability of 10ton/a of tritiated water was set up in the middle of 2004 at China Academy of Engineering Physics (CAEP). It has successfully fulfilled the demonstration experiment of recovering deuterium from deuterium contained water and simulation operation of recovering tritium from tritiated water. Total concentration factor of CECE about 4, and the separation factor of tritium around 10 for operation time of 240h with this system. The GC system of 50m3/d has successfully recovered 90% hydrogen from 10m3tritiated hydrogen gas in 6h and the tritium concentration in this part was depleted more than 1000 times. This experimental system served as an important step stone for further engineering works.
