Beijing, October 29 – Neftegaz.RU.Power start-up of Tianwan NPP (TNPP) power unit №4 being constructed in China under the Russian NPP design with VVER-1000 reactors took place on October 27th. The 4rth power unit produced the 1st kilowatts of output to the national grid system.
In compliance with the permit obtained from the Chinese regulatory authority the reactor plant of power unit No.4 was brought to 25%, followed by the turbine push start and the electrical tests of the excitation and power output systems. This work resulted in the power unit connection to the power system. All the power unit systems were operating in the design mode.
According to Alexey Likhachev, Director Gen. of ROSATOM, «Tianwan NPP currently is the largest Russian-Chinese power project that is being developed successfully due to the synergism of specialists from two countries. And start-up of the fourth power unit is a further proof thereof. At the Tianwan NPP site we became a united team with our Chinese colleges, which facilitates the result achievement. Surely our further cooperation both in the construction of the next stages of Tianwan NPP and on a new Xudapu site shall also be efficient and fruitful» .
«Further we have to check the reactor operation at the 200 MW output and perform the dynamic tests at the power levels of 50%, 75% and 100%. Upon successful passing of the tests the demonstration tests of the power unit continuous operation at the rated load shall be performed during 100 hours. Upon its completion a preliminary acceptance of the power unit shall be performed that shall become a benchmark for a 2-year guarantee operation of the power unit», Likhachev noted.
