The first standby diesel power plant (SDPP) was successfully launched at Akkuyu NPP Unit 1 (the plant is being built by Rosatom in Türkiye).
The equipment commissioning specialists started the installation at idle and began preparations for a step-by-step verification of its operation under load. In total, three standby diesel generator sets (DGS) will operate at each Unit the Akkuyu NPP. After switching on, about 50 control operations will be performed at the DGS in various operating modes. After the specialists are convinced of the reliability of all DGS systems when operating at the rated power level, the installation will be switched to the “on-duty” mode. The standby diesel generator is working in this mode during the NPP operation. The readiness to receive the SDPP load does not exceed 15 seconds from the moment of receiving the start signal. The whole process takes place automatically. In addition, putting diesel generators on duty is a mandatory requirement for the start of the reactor cold and hot tests.
“Standby diesel power plants are one of the key elements of nuclear power plant safety systems. Each Unit of the Akkuyu NPP is equipped with three such power plants. They serve for the autonomous power supply of the nuclear power plant in case of a shutdown of the main power supply. Each of the three standby diesel power plants is equipped with a diesel generator set. Today we have launched the first of them, the DGS of the standby diesel power plant of the normal operation system. Together, three diesel generators on each Unit will be able to provide electric power to all the unit systems provided for by the project for at least 72 hours without refuelling,” said, Akkuyu Nuclear JSC Deputy Director of the NPP under Construction – Chief Technology Officer Andrey Zhukov.
