SN Nuclearelectrica SA (SNN) is the only nuclear energy producer in Romania. The company operates at Cernavoda NPP two CANDU ( Canada deuterium uranium) reactors.
Cernavoda NPP project is based on the CANDU 600 reactor type developed by AECL Canada. This type of reactor is part of the reactor genre that uses neutron moderating technology with heavy water. CANDU technology is used worldwide in several countries, Canada, Argentina, Romania, China, Korea. The nuclear fuel is natural uranium. The fuel is produced at FCN Pitesti, SNN subsidiary, Romania having an integrated energy production cycle based on nuclear technology.
From the technical standpoint, both in the design and construction phases, the highest international standards have been applied.
SNN/Cernavoda NPP is affiliated to multiple international organizations, by means of which it has access to the most recent research results in the fields related to CANDU technology (through Candu Owner’s Group-COG) and engineering studies applicable in the nuclear industry. These affiliations cover the operational experience exchange with nuclear power plants from all over the world through the World Association of Nuclear Operators (WANO) and specifically for CANDU, through COG. Thus, through the operational and technical experience exchange, SNN/Cernavoda NPP is aligned to the level of the global nuclear industry.
Based on the most recent global ranking of nuclear power plants, dated 2019, based on the capacity factor reached by each nuclear power plant since their commissioning, Unit 2 ranks 1st in the world with a capacity factor of 93,3%, and Unit 1 ranks 4th with a capacity factor of 89,7%. Romania ranks 1st in the world out of a total of 440 reactors.
Rigurous implementation of the maintenance programs and of a constant project improvement program has allowed the operation of the power plant at a capacity factor higher than 90%.
As well, the operational results of Cernavoda NPP depend on the very good quality of the fuel bundles manufactured by FCN Pitesti.
SNN has a market share of approximately 20% and it generates clean energy, without CO2 emmissions. In 25 years of operation, SNN has avoided the release into atmosphere of 195 million tons of CO2 and, yearly, the company avoids the release of 10 million tons of CO2.
