The RV-1 nuclear reactor, now repurposed and known as Gamma rays sterilization plant ('Pegamma'; Spanish: Planta de Esterilización por Rayos Gamma),[1] is a facility located in Altos Mirandinos, Miranda, Venezuela.[1] It was the only nuclear reactor in Venezuela and one of the first reactors in Latin America.[2][3][lower-alpha 1] Currently, it is used as a gamma ray facility for microbiological sterilization of surgical supplies, packaging, medicine and dry food.[4]
Characteristics
The RV-1 was a pool-type material testing reactor (MTR) with a capacity of 3 megawatts of thermal power. It contained 20% enriched uranium as core fuel and used light water as both coolant and neutron moderator.[5]
History
During the regime of president Marcos Pérez Jiménez, Venezuela became member of the International Atomic Energy Agency after purchasing the RV-1 reactor from General Electric in 1956.[6][7] The project was supported by the administration of United States President Dwight D. Eisenhower, to help promote the Atoms for Peace program,[8][9] with the United States donating United States dollar 300,000 for the construction of the reactor.[9] The reactor was constructed in the grounds of the Venezuelan Institute of Neurology and Brain Research (IVNIC, now known as IVIC - Venezuelan Institute for Scientific Research) under the supervision of Humberto Fernández-Morán; he never saw the project finished, as he went into exile after the Pérez Jiménez regime fell in 1958.[6]
The reactor reached criticality in 1960 and was used for several decades to perform physics research, radiochemistry, production of radioisotopes and as neutron source.[5] RV-1 was last operated in March 1991 and the decision to permanently shutdown the reactor was made in 1997.[5] The core was later dismantled and sent back to the United States.[8]
Repurposing and cancelled sequels
The Venezuelan government approved 2.1 million dollars to repurpose the reactor in 2010.[1] Under the name 'Pegamma',[1] IVIC received the authorization in 2004 to use the renewed reactor facility as an industrial irradiation plant, with a cobalt-60 gamma rays source with a capacity of 1 megacurie.[4][8]
Venezuela later announced plans to build a nuclear power station in 2010.[10] The government signed an agreement with Russia for the purchase and installation of two new nuclear reactors,[8] but after the 2011 Fukushima Daiichi nuclear disaster in Japan, President Hugo Chávez announced a halt to plans on building a nuclear power plant.[8][11]

Notes
- ↑ According to the IVIC,[2] RV-1 was the first nuclear reactor in Latin America, other sources consider RA-1 Enrico Fermi (criticality in 1958) in Argentina as such.[3] Consider also Brazilian IEA-R1 (pt) (criticality in 1957).
