Pilcaniyeu enrichment plant, Río Negro

Court awards compensation to worker who contracted kidney cancer at Pilcaniyeu enrichment plant

A man who worked for Invap in the 1980s must be compensated for by ART [Aseguradoras de Riesgos del Trabajo (occupational risk insurance)] after he suffered kidney cancer with metastasis to the lung. The expertise indicated a high probability that it was caused by the manipulation of dangerous elements with the security conditions of the time, which have changed substantially today.
The Court rejected the responsibility of the state company. (Bariloche2000 Feb. 20, 2024)

Court awards compensation to worker who contracted kidney cancer at Pilcaniyeu enrichment plant

A worker from the Invap SE company who performed tasks for several years at the Pilcaniyeu uranium enrichment plant without proper safety measures contracted kidney cancer with metastasis to the lung after maintaining regular and prolonged contact with highly toxic substances and must be compensated by the ART [employer liability insurance] responsible for the coverage.
This was established by the Second Labor Chamber of this city in a ruling that considered proven "the causal relationship" between the tasks carried out by the plaintiff, Luis Prieto, and the pathology he contracted and which forced his left kidney to be removed, in addition to undergoing to long chemotherapy treatments. [...]
In its defense, Invap pointed out that the Pilcaniyeu plant did not work with enriched uranium but with natural uranium "and for this reason there were no possible harmful effects on health." [...] (Río Negro Sep. 11, 2023)

Argentina to restart Pilcaniyeu enrichment plant

In five weeks, the Pilcaniyeu plant will resume production of enriched uranium, Argentine Planning Minister Julio de Vido said at a Nuclear Suppliers Group meeting in Buenos Aires. The reopening of the Pilcaniyeu Technological Complex, located some 1,600 kilometers southwest of Buenos Aires and managed by the National Atomic Energy Commission , has required an investment outlay of 27 million dollars. Argentina produced uranium on an experimental scale at Pilcaniyeu in the 1980s, when the country developed an enrichment method, but it later halted production at the plant. With the reopening of the plant, Argentina will be producing that nuclear fuel component on an industrial scale for the first time. (MercoPress June 26, 2014)

Argentina resumes uranium enrichment at Pilcaniyeu

On Oct. 25, 2010, president Cristina Kirchner re-inaugurated the Pilcaniyeu uranium enrichment plant in Río Negro Province. First samples of enriched uranium will be obtained in September 2011. The plant had already been in operation in 1982/1983 but was halted for various reasons. (Clarín Oct. 26, 2010)

Dioxitek UO2 plant in Córdoba to be closed for good

After a long-standing demand of environmentalists and neighbors, it was expected in the Municipality of Córdoba yesterday that Dioxitek presents a note announcing the stoppage at the uranium processing plant in Alta Córdoba. Many residents were alarmed by the explosion on Thursday (Nov. 6) a few blocks away. The processing of nuclear fuel is essential for the operation of nuclear power plants, but production is unviable in the middle of a city.
At the site there is a place that employees and neighbors called "el bochón" where a lot of toxic waste was buried. Remediation is expected to involve the transport of more than 40 trucks, which would have to pass through populated area.
Anyway, with or without notice, the city will close the plant on Monday (Nov. 10), as indicated within the last extension of the operating license, which expires today. This was confirmed to La Voz by the Interior Secretary, Control and Coexistence, José Fernández, who said that this is a final measure. He said that this determination is not related to the explosion of the tank. (La Voz Nov. 8, 2014)

Protests in Río Tercero against proposed relocation of Dioxitek UO2 plant from Córdoba

A thousand people rallied late on Friday (May 31) in a march through downtown streets of the city Río Tercero, against the possible establishment of the state-owned company Dioxitek. (La Voz June 1, 2013)

CNEA considers relocation of Dioxitek UO2 plant from Córdoba to Río Tercero

The state company Dioxitek submitted to the municipality of Río Tercero a prefeasibility land use order to move its uranium dioxide processing plant to the site of the Military Factory in this city.
Dioxitek began operating in 1982 in Alta Córdoba district, the provincial capital. After a long series of conflicts for its location in the urban area, the company agreed with Cordoba town last November to relocate within 18 months. According to reports, the alternative being considered is also a property of Military Industries, in the place of José Quintana (between Despeñaderos and Alta Gracia). (La Voz May 15, 2013)

CNEA denies plan to relocate Dioxitek UO2 plant to Sierra Pintada (Mendoza)

The National Atomic Energy Commission (CNEA) informed that it has no plans to relocate the Dioxitek plant that is located in Córdoba, nor the area called "El Chichón", to the San Rafael uranium mine complex in Mendoza. (Los Andes Nov. 11, 2012)

Dioxitek considers doubling of nuclear fuel production capacity

The chairman of Dioxitek S.A., Santiago Morazzo, announced that he is studying the construction of a new plant that will double its production to 300 tonnes per year, and it will be located outside the urban area of Córdoba. (Clarín Aug. 1, 2007)

Environment defense foundation (FUNAM) denounces the environmental situation at the Dioxitek S.A. uranium dioxide plant in Córdoba

On July 25, 2006, the Environment defense foundation (FUNAM) denounced the environmental situation at the Dioxitek S.A. uranium dioxide plant in Córdoba, where more than 36,000 tonnes of radioactive waste are stored on-site without proper protective measures. FUNAM requested that the CNEA remedies the site immediately and the Municipality closes the plant of Dioxitek S.A..


Centro Atómico Ezeiza (CEA)

Well water near Ezeiza nuclear center contaminated with uranium and other toxic substances

The well water that is being used by thousands of inhabitants of Ezeiza, Esteban Echeverría and La Matanza is contaminated with uranium and other toxic substances originating from the Centro Atómico Ezeiza (CAE). This was revealed in a report prepared by geologist Fernando Diaz of the University of Buenos Aires.
74% of the wells sampled (36 out of 46) showed concentrations of uranium and nitrate in excess of WHO's preliminary drinking water guideline values (15 micrograms per litre, and 50 milligrams per litre, respectively). 1,618,069 people are living in the three localities affected. Nearly 47% of them (760,000) are not connected to the potable water network and are therefor using well water. (Los Andes, March 19, 2005)
CNEA maintains that the uranium concentrations found (up to 56 g/L) do not exceed the Argentinian standard of 100 (!) g/L. (El Santacruzeño March 22, 2005)

A study performed by the U.S. Environmental Protection Agency (EPA) on behalf of the Buenos Aires Province Secretariat of Environmental Policy (SPA) found that the uranium concentration in 10 of 51 samples taken exceeds 20 micrograms per liter, which is the limit established by the Province. The average concentration in those wells was 26 micrograms, reaching almost 35 micrograms per liter in one case. (Clarín Nov. 12, 2005)
> View details (SPA - in Spanish)
The Argentinian nuclear regulatory authority (ARN ) maintains that (a) the uranium detected was natural rather than enriched uranium, (b) the concentrations found are within the range of values naturally found in the area, (c) the Argentinian standard of 100 g U/L is appropriate for radiation protection - ignoring the fact that the WHO provisional guideline of 15 g/L was established for the chemical toxicity of uranium.

After reiterated complaints, the Buenos Aires Province Secretariat of Environmental Policy is planning to investigate if "genetic mutations" exist in residents living near the Centro Atómico Ezeiza. (Diario Uno de Mendoza June 26, 2006)

The Nuclear Regulatory Authority (ARN), through its director Raúl Racana, maintained that the waters of the Buenos Aires agglomeration neighbouring the Nuclear center of Ezeiza, are not contaminated. He assured that there "exists total security for the population" of Ezeiza and the environs.
The position of the ARN was set out to Clarín as a result of a special report published Sunday 19 of July, where it was revealed that the investigation on the possible contamination of the Puelche aquifer with uranium takes up to 9 years of delay. According to a report ordered by the judge of the cause, the aquifers would have received uranium residues of the Nuclear center, becoming a serious risk for approximately one million inhabitants of Ezeiza, Esteban Echeverría and La Matanza.
