Abstract The National Research and Development Institute for Cryogenics and Isotopic Technologies (ICSI Rm. Valcea) was established in 1970 as a research entity with the main goal of developing a heavy water production technology. One of the departments of the institute, entitled ICSI Nuclear, is oriented toward the development of a heavy water detritiation technology with the main beneficiary being the Cernavoda nuclear power plant. Thus, ICSI Nuclear has completed the technical project of the Cernavoda Tritium Removal Facility (CTRF). This paper focuses on the CTRF front end (water detritiation system) and will analyze achievement of the nominal regime at start-up and analysis of the transient regimes that may occur during normal operation and their impact on the water detritiation factor. Analysis results can become input for improvement of the CTRF control and instrumentation system, for subsequent operating facility procedures, and for verification of the isotopic exchange software models corresponding to these modes of operation.

一个脱硝设施运行的瞬态制度分析

摘要 国家低温和同位素技术研究与发展研究所 (ICSI Rm. Valcea) 成立于 1970 年，是一个研究实体，主要目标是开发重水生产技术。该研究所的一个部门，名为 ICSI 核，致力于开发重水脱硝技术，主要受益者是 Cernavoda 核电站。至此，ICSI核能完成了Cernavoda氚去除设施（CTRF）的技术项目。本文重点介绍 CTRF 前端（水除垢系统），将分析启动时标称状态的实现，并分析正常运行期间可能出现的瞬态状态及其对水除垢因子的影响。
