At the end of June 2019, warranty tests of the turbine K-1000-60 / 1500-2 upgraded by Turboatom were held at power unit No. 5 of the Kozloduy NPP (Bulgaria).
The equipment of the updated power unit passed the warranty tests, which confirmed the calculated figures, and even exceeded their value.
The main task of the test was to check for the achievement of the guaranteed performance of the turbine as a result of the reconstruction, namely, the efficiency of the HPC.
The contract for the modernization of the equipment of the Kozloduy nuclear power plant was signed in January of this year. The modernization project involved work on the reconstruction of the wetted part of the high-pressure cylinder of the turbine K-1000-60 / 1500-2 with a capacity of 1000 MW. The use of innovative designs and technologies allowed increasing the electrical capacity of the unit number 5 of Kozloduy NPP.
NPP Kozloduy is located on the bank of the r. Danube, 200 km north of the capital Sofia and 5 km from the city of Kozloduy, after which the power plant got its name. The plant has two operating WWER-1000/320 power units with a total capacity of 2000 MW.
