Dhaka, Dec 12, 2017 (PR) - Russia has launched two nuclear power units within just a week, making a record in their nuclear industry history. First fuel assembly was loaded on December 6 into the reactor core of Unit- 4 of Rostov Nuclear Power Plant and the same for Unit-1 of Leningrad Nuclear Power Plant-2 was done on December 8.
First fuel loading means the beginning of first criticality i.e. attainment of the controlled nuclear chain reaction and taking the reactor unit to the minimum controlled power level. The first criticality is one of the key stages of putting a power unit into operation with the main task to confirm that the unit will operate reliably and safely at design parameters during its entire service life.
Unit-1 of Leningrad Nuclear Power Plant-2 LNPP is equipped with the latest Generation III+ VVER-1200 reactors, which correspond (are aligned with) the post-Fukushima safety measures. Earlier on November 30 Bangladesh began the construction of the country’s first nuclear power plant at Rooppur, which will have two similar VVER-1200 units.
“Within 30 days, the reactor facility will be brought to the minimum controlled power level. These operations involve a large range of inspections and tests at different stages during the increase to the power level, as well as testing and revision of various items of equipment to confirm the reliability and safety of the power unit for further operation," said Andrey Petrov, Director General of Rosenergoatom, a Russian nuclear power plants operations subsidiary of Rosatom State Atomic Energy Corporation.
“Unit 1 of the Leningrad Nuclear Power Plant-2 belongs to the latest Generation III+. This is the second innovative unit of its kind. In February 2017, Russia became the world’s first country to launch a nuclear power unit of Generation III+ at the Novovoronezh Nuclear Power Plant,” added Valery Limarenko, President of ASE Group of Companies, an engineering division of Rosatom State Atomic Energy Corporation.
On the other hand, Rostov Nuclear Power Plant is equipped VVER-1000 reactors. This kind of reactor has a long safety record and are installed at nuclear power plants in Russia, India, China, Bulgaria and other countries.

Leningrad Nuclear Power Plant: The Leningrad NPP is the largest producer of electricity in Northwest Russia. It is located in Sosnovy Bor, 40 km from the city of St. Petersburg and produces around 50% of the electricity generated in the region.
Rostov Nuclear Power Plant: Rostov NPP is located 13.5 km from the city of Volgodonsk. It is the largest enterprise of the power sector in South Russia, which produces 46% electricity in the region. The commissioning of Unit 4 will bring the share of the plant in electricity production to 54%.
