This was stated by the head of SE NNEGC Energoatom Petro Kotin during a visit to Zaporizhzhya NPP on the 25th anniversary of NNEGC's establishment and the start of operation of the power unit 6. Adviser to Prime Minister Yuriy Boyko and a member of the National Energy and Utilities Regulatory Commission of Ukraine (NEURCU) Dmytro Kovalenko attended the events as well.

The guests got acquainted with the operation of the Spent Fuel Drying Storage (SFDS) at the plant site. Spent nuclear fuel has been successfully and reliably stored at the plant for 20 years. The Storage facility is able to provide all the needs of NPP for spent fuel storage.

At Zaporizhzhya NPP power unit 6, the working delegation visited the turbine hall and the main control room. 25 years ago, on October 19, 1995, the ZNPP unit 6 was connected to the energy system of Ukraine. Since then, the Zaporizhzhya nuclear power plant has had an installed capacity of 6,000 MW and has become the Europe's largest and the world's third-largest nuclear power plant.

The power unit 6 became the first nuclear industrial facility put into operation in Independent Ukraine. Its commissioning took place on October 21, 1996 – as part of SE NNEGC Energoatom. In a quarter century of safe and reliable operation, the sixth power unit has already generated more than 175 bln kWh of electricity.

The guests also visited the central hall of the training center (building «Г»), where the repair staff and the management personnel of NNEGC undertake training. Since 2017, the training center has been using the first-of-a-kind full-scale simulator of the VVER-1000 reactor unit, other simulators created according to the best global methods, as well as 22 training laboratories.

An emergency response drill of the staff was conducted, followed by congratulations of the ZNPP staff in the local cultural centre on the 25th anniversary of Energoatom and the anniversary launch of the sixth power unit. The festivities and a small concert took place in compliance with all quarantine security measures.

For reference.

The construction of ZNPP unit 6 began in 1987 and was scheduled for commissioning in 1990, but due to a moratorium on the construction of new NPPs after the Chornobyl disaster, the nearly completed facility had to be put on hold. After the lifting of the moratorium in October 1993, the unit was physically started on October 6, 1995, and 14 days later, it was connected to the unified energy system of Ukraine with an electric load of 300 MW. On October 21, 1996, Zaporizhzhya NPP unit 6 was put into commercial operation (being a part of SE NNEGC Energoatom).

In 2000, following the performance results, Zaporizhzhya NPP was recognized as one of the top three nuclear power plants in the world, which fully meets the IAEA requirements.

ZNPP (construction began in 1977) operates six out of the 15 existing power units in Ukraine, generates about 40 bln kilowatt-hours of electricity per year, which is more than 20% of total domestic electricity generation.

ZNPP became the first and only nuclear power plant in the country to build the in-site Spent Fuel Drying Storage (SFDS). Its technology is recognized as the safest and most modern in the world, based on the storage of spent fuel assemblies in ventilated concrete containers located on the site within the nuclear power plant.

ZNPP SFDS is capable to accommodate 380 containers, which will ensure the storage of spent fuel assemblies for the next half a century, which will be removed from ZNPP reactors throughout its service life. The first spent fuel container was loaded into storage on August 24, 2001. At present, there are more than one and a half hundred of them containing about 4,000 spent fuel assemblies.

In January 2021, ZNPP reached its maximum capacity due to the commissioning of a 750 kV power transmission line from ZNPP to the Kakhovska substation. In a long run, the Kakhovska substation will be essential to the synchronization of the Ukrainian power system with the European one.
