Last Updated: June, 2017

Forcibly incorporated into the Soviet Union in 1940, Latvia regained its independence in 1991 when the Soviet Union collapsed. Riga has since joined NATO and the European Union, and is a member of relevant nonproliferation organizations and regimes. Latvia does not possess or produce nuclear, chemical, or biological weapons.


Latvia is a member of the Nuclear Suppliers Group (NSG) and a party to both the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) and the Comprehensive Nuclear Test Ban Treaty (CTBT). Riga also has an Additional Protocol in force with the International Atomic Energy Agency (IAEA).

One of the first research reactors in the USSR, the Salaspils 5MW research reactor was constructed in 1959 at the Latvian Institute of Nuclear Physics, 20 miles from Riga, and went critical in 1961. [1] It was permanently shut down in July 1998 due to a lack of government funding and safety concerns. [2] All fresh and spent fuel was removed from the reactor site. [3] The University of Latvia maintained the reactor site, but in February 2015 withdrew from the project due to financial constraints. [4] In August 2006 the Latvian government approved a decision to build a National Multipurpose Cyclotron Center on the Salaspils site, to produce radioisotopes for applied medical science as well as research. [5] This decision was subsequently cancelled in August 2015. [6] In June 2016 the Center of Nuclear Medicine opened a separate cyclotron complex unrelated to the canceled Salaspils project. [7]

The United States and other members of the international community have long been involved in working to improve the security of materials stored at Salaspils. In the 1990s, the IAEA and a number of countries, including Finland, Sweden, and the United States, provided technical assistance and funding to Latvia to improve material control and accounting regulations and physical protection systems at Salaspils. [8] With the May 2005 transfer of 2.5kg of fresh highly enriched uranium (HEU) fuel and the 2008 transfer of 14.4kg of spent HEU fuel from Salaspils to Russia, all highly enriched uranium has been removed from Latvia. [9] Russia, the United States, and the IAEA assisted Latvia with the secure transfer of the HEU.

The National Nuclear Security Administration (NNSA) of the US Department of Energy (DOE) has also assisted Latvia in improving the state's export control system, including by organizing training courses for Latvian customs officials. [10] Latvia made significant improvements to its export control system in order to meet European Union (EU) standards before becoming a member in May 2004, introducing a catch-all clause to its list of dual-use technologies subject to controls, and creating a database that contains information on licenses, import certificates, end-use certificates, and companies involved in transfers of strategic goods. [11]

The utilities of Estonia, Latvia, and Lithuania released a joint feasibility study in October 2006 calling for the construction of at least one new nuclear reactor of between 800 and 1,600 MW in Lithuania to replace Ignalina-2, which closed in December 2009. [12] Initially, Latvia, Lithuania, Estonia and the Japanese company Hitachi were to be joint owners of the Visaginas Nuclear Power Plant Project in Lithuania, where construction of an Advanced Boiling Water Reactor was slated to begin in 2015. [13] However, the project stalled due to concerns about costs and the level of participation by the various stakeholders, including the Latvian government, which stated that it will only participate if the plant is proven to be economically viable. [14] The project was cancelled in early 2017, when the Lithuanian Prime Minister stated in an interview that the Visaginas project "is no longer on our agenda." [15]


Latvia acceded to the Biological and Toxin Weapons Convention (BTWC) in February 1997 and joined the Australia Group in June 2004. There is no evidence that Riga possesses or seeks to develop biological weapons.


There is no evidence to suggest that Riga possesses or seeks to develop chemical weapons. Latvia is a party to the Chemical Weapons Convention (CWC) and a member of the Australia Group. Latvia first developed an export control system in 1995, following the guidelines of the Australia Group with regard to CW-relevant technologies, and further revised these regulations upon accession to the CWC in 1997 and in subsequent years. [16]


Latvian facilities that once supplied the former Soviet Union with commodities controlled by the Missile Technology Control Regime (MTCR), such as thermal protection materials for space craft, electronics, radar, and sensors for missiles, no longer produce or export such items. [17] Latvia has a List of Dual-Use Goods and Technologies, and controls the export of other domestically-produced components that could be used to build aircraft or missiles. [18] Although not a member of the MTCR, Latvia abides by the guidelines of the regime. [19]
