Abstract The multifunctional Tritium Removal Facility (TRF) has been designed for the heavy water research reactor PIK in Russia. Along with the extraction of tritium and protium from a heavy water reflector of the reactor, the TRF provides the processing of heavy water waste and the production of tritium-free heavy water. The combined electrolysis catalytic exchange process and hydrogen cryogenic distillation are used at the TRF. A number of investigations have been made to obtain data for the TRF design. At present, the facility is under construction and a detailed design is being completed. The possibility of processing heavy water waste to produce heavy water simultaneously with the extraction of tritium and protium from the heavy water reactor will improve the functionality and economic efficiency of the TRF. The basic technological scheme of the facility and the main modes of its operation are presented along with the progress of the construction of the facility building and engineering systems.

摘要 多功能氚去除设施（TRF）是为俄罗斯重水研究堆PIK设计的。除了从反应堆的重水反射器中提取氚和氚之外，TRF 还提供重水废物的处理和无氚重水的生产。TRF 使用联合电解催化交换工艺和氢气低温蒸馏。为了获得 TRF 设计的数据，已经进行了许多调查。目前，该设施正在建设中，正在完成详细设计。在从重水反应堆中提取氚和氚的同时处理重水废物以生产重水的可能性将提高 TRF 的功能和经济效率。
