自1994年以来，第一代氢同位素分离工艺--热循环吸收工艺（TCAP）已在萨凡纳河场址用于氚分离。为了准备更换，开发了下一代TCAP工艺。这种新方法简化了柱设计，降低了热循环系统的设备要求。在实验室中制作并安装了一个12米的实验柱，以证明其性能。这种新的设计及其初步测试结果在第八届国际氚科学与技术会议上发表，并发表在《聚变科学》杂志上。技术人员：第54卷，第2期，第399页（2008年）。此后，我们完成了启动，并在实验装置中演示了氚和氘的分离。该装置已运行超过200个周期。将含25%氘的原料分离成两股物流，每股物流的纯度高于99.7%。
Abstract The first generation of a hydrogen isotope separation process called the thermal cycling absorption process (TCAP) has been in service for tritium separation at the Savannah River Site since 1994. To prepare for replacement, a next-generation TCAP process has been developed. This new process simplifies the column design and reduces the equipment requirements of the thermal cycling system. An experimental 12-m column was fabricated and installed in the laboratory to demonstrate its performance. This new design and its initial test results were presented at the Eighth International Conference on Tritium Science and Technology and are published in the proceedings, Fusion Sci. Technol., Vol. 54, No. 2, p. 399 (2008). We have since completed the start-up and demonstrated the separation of protium and deuterium in the experimental unit. The unit has been operated for more than 200 cycles. A feed of 25% deuterium in protium was separated into two streams, each with better than 99.7% purity.
