China experimental fast reactor is the first fast reactor. As the highest law during the operation of nuclear facilities, the technical specifications play a vital role in the stable operation of fast reactors. The review of operation technical specifications is a comprehensive review, especially for fast reactor, which is the first time in China. There are great differences between fast reactor and traditional pressurized water reactor in technology. Due to the current regulations and standards in China, most of them are formulated according to PWR. The design of the new reactor has not formed a complete standard system, especially the operation mode. The modification of the operation mode is a major modification of the operation technical specification. This paper mainly describes the core problems encountered in the nuclear safety review of the technical specifications of China experimental fast reactor, such as the operation mode, the operability of the primary circuit sodium pump, the overpressure protection system, the periodic test of the containment chamber for sodium fire and argon release accidents, and finally obtains a suitable solution. It provides technical support for the continuous development of China's fast reactor industry. The review of technical specifications for fast reactor has achieved good practical results and provided valuable experience for subsequent commercial power plants.
