Nuclear Power in Armenia
(Updated October 2012)
- Armenia has relied heavily on nuclear power since 1976.
- It has one reactor in operation and the government has approved a joint venture to build another by 2020.
Although Armenia has only one operating nuclear reactor, this unit supplied 33% of the total electricity produced in 2011 – 2.4 billion kWh net. Of the 5.67 billion kWh gross generation in 2009, nuclear supplied 44%, hydro 36% and gas 20%. Electricity consumption per capita is about 1700 kWh/yr. Natural gas, which is imported from Russia, is its main source of primary energy.
The country is a member of the Commonwealth of Independent States and has a population of 3.25 million.
Operating and planned nuclear power reactors in Armenia
|Total operating (1)
One Russian VVER-440 nuclear power plant operates at Metsamor a , 30 km from the capital Yerevan.
Two model V-230 reactors, each of 407.5 MWe gross (376 MWe net), were built at Metsamor on solid basalt and supplied power from 1976 and 1980 respectively. Design life was 30 years. These were the first Russian plants designed to be built in a region of high seismicity and were modified accordingly to be designated V-270. Plans for units 3 & 4 at the site were abandoned after the 1986 Chernobyl accident.
In December 1988, a powerful earthquake, resulting in the deaths of at least 25,000 people, occurred in northwestern Armenia. The Metsamor nuclear power plant 75 km from the epicentre continued operating normally with no damage, but both units were subsequently shut down in 1989 due to safety concerns regarding seismic vulnerability.
Unit 1, after 13 years operation, is now being decommissioned. In 1993, it was decided to restart the second unit due to the severe economic crisis and this was achieved in 1995, after 6.5 years shutdown. Since then the International Atomic Energy Agency (IAEA) has been participating in safety improvements at the plant, which was scheduled to close in 2016 but will now continue until the new unit is commissioned b .
All fuel is supplied by Russia, but this incurred significant foreign debt - some $40 million.. As a result, the plant has been operated by a subsidiary of RAO UES and Rosenergoatom since 2003, as part of an arrangement to help pay off those debts to TVEL. This agreement, now with Inter-RAO, was extended by five years in 2008 but may be terminated earlier.
The present Metsamor plant is a concern to the European Union (EU) and to
neighbouring Turkey, 16 km away. There have been various calls to shut it down
before 2016, but Armenia is very dependent on it and has said that it will
remain open until a replacement is commissioned. According to a 1999 agreement with
the EU,c Armenia would close the plant before the
end of its design lifetime, provided that alternative replacement capacity is
available. The EU undertook 'stress tests' on it in April 2012, following those
in Europe. In October 2012 the government confirmed a 10-year life extension.
New nuclear plant
In 2007, Armenia adopted a new energy strategy
focusing on security of supply through diversification and the use of nuclear
energy as well as renewable energy sources. Later in 2007, the energy minister
announced a feasibility study for a new unit at Metsamor, the investigation
being carried out with assistance from Russia, the USA and the International
Atomic Energy Agency. The new plant was then expected to go on line about
In February 2009, the government announced a tender
for a new 1000 MWe unit. In May 2009, Australian company Worley Parsons was
chosen to administer the project, and a $460 million management contract was
signed in June. Legislation providing for construction of up to 1200 MWe of new
nuclear capacity at Metsamor from one or more reactors was passed in June
In December 2009, the government approved
establishment of JV Metzamorenergoatom, a 50-50 Russian-Armenian joint stock
company set up by the Ministry of Energy and Natural Resources with
Atomstroyexport, with shares offered to other investors1.
This will build a 1060 MWe AES-92 unit (with a VVER-1000 model V-392 reactor)
with a service life of 60 years at Metsamor. In March 2010 an agreement was
signed with Rosatom to provide the V-392 reactor equipment for it.
In August 2010, an intergovernmental agreement was
signed to provide that the Russian party will build at least one VVER-1000
reactor, supply nuclear fuel for it and decommission it2.
Construction was to commence in 2012 or early 2013 and is expected to cost US$5
billion. The customer and owner of new reactors, as well as electricity
generated, will be Metzamorenergoatom, and Atomstroyexport will be the principal
contractor. Armenia undertakes to buy all electricity produced at commercial
rates, enabling investors' return on capital, for 20 years. Metzamorenergoatom
is to fund not less than 40% of the construction, and early in 2012 Russia
agreed to finance 50%. The latest date for commissioning is 2019-20.
The government has signed an agreement to become a
partner in the international uranium enrichment centre at Angarsk in Siberia,
under Russian leadership and IAEA supervision, from 2013.3 Kazakhstan is also a partner in it.
Russia's Atomredmetzoloto (ARMZ) is participating in
a 50-50 joint venture Armenian-Russian Mining Company set up in 2008 to explore
for uranium in Armenia4. This is at least
expected to provide for the country's domestic needs, and export of surplus is a
In 1993, the Armenian Nuclear Regulatory Authority (ANRA) was established as regulator. Also in 1993, the government established a new body under the Ministry of Energy to operate the plant, and in 1996 this was taken over by Armenian NPP (ANPP) joint stock company. At the same time, the Department of Atomic Energy was established within the Ministry of Energy.
Armenia has been a member of the International Atomic Energy Agency since 1993, and of the World Association of Nuclear Operators (WANO) since 1996.
Armenia has been a party to the Nuclear Non-Proliferation Treaty since 1993, and in 1997 signed the Additional Protocol on its safeguards agreement with the International Atomic Energy Agency. It has been party to the Vienna Convention on civil liability for nuclear damage since 1993.

b. The reactor commenced operation in 1980 and has a design lifetime of 30 years. Taking into account the period between 1989 and 1995 when the unit was offline, this would imply that it would reach the end of its design lifetime by 2016. However, early in 2012 it was confirmed that this would be extended until after the new unit is commissioned. [Back]
