Test of the cold traps in the JAERI Fuel Cleanup System in the Tritium Systems Test Assembly

摘要

A plasma exhaust processing subsystem, JAERI Fuel Cleanup (JFCU) is a major subsystem of the TSTA fuel loop. The cold traps in the process are designed to capture tritiated water and separate it from tritium free gas stream. In the deuterium testing of the JFCU, the cold traps worked poorly when it is switched over for regeneration. Tests were conducted to investigate this process and solve the problem. Changing packing of the traps or valve sequence did not improve the trapping efficiency. It was decided to install small molecular sieve beds to improve the characteristics of the entire process.
