Deadline for official comments from IAEA member states is December 31, 2013.
Making nuclear fuel should be taken out of the hands of individual nations and put into multilateral groups in order to keep countries from secretly developing atomic weapons, a UN report said.
The report by a panel of experts to Mohamed ElBaradei, head of the International Atomic Energy Agency (IAEA), comes ahead of a meeting in New York in May 2005 to review the nuclear Non-Proliferation Treaty (NPT), which gives the IAEA a mandate to verify that atomic programs in over 180 signatory nations are peaceful.
ElBaradei has warned that the NPT, in effect since 1970, has serious flaws at a time when the international community is worried about atomic programs in Iran and North Korea.
The world cannot continue allowing countries to develop the ability to make nuclear fuel that can also be used to make atomic bombs, ElBaradei told AFP in an interview in January.
"We just cannot continue business as usual that every country can build its own factories for separating plutonium or enriching uranium.
Then we are really talking about 30, 40 countries sitting on the fence with a nuclear weapons capability that could be converted into a nuclear weapon in a matter of months," ElBaradei said.

UN atomic energy chief Mohamed ElBaradei has proposed that all countries lead by example by committing not to build facilities for uranium enrichment and nuclear reprocessing for five years.
ElBaradei told the Asahi Shimbun in its Jan. 7, 2005, edition that a global freeze on construction for uranium enrichment and nuclear reprocessing would be discussed at a May conference in New York on the Nuclear Nonproliferation Treaty.
Such a moratorium would have value as it would place "some limitation on the right of every country to develop a full (nuclear) fuel cycle," he said.
He said a global freeze could last for five years or "until we have completed our work on how we can have an international arrangement for the fuel cycle."
"We have enough capacity in the world for enrichment or reprocessing," said ElBaradei who heads the International Atomic Energy Agency (IAEA).

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.

Protests in Paraguay against Argentina's plan to build Dioxitek UO2 plant near border
About 400 people demonstrated today (Mar. 14) in the Paraguayan city of Pilar (southwest) against the planned construction of a nuclear plant in Argentina's province of Formosa near the border with Paraguay, the local police told Efe.
The protesters, many of whom hoisted Paraguayan flags, gathered for about two hours in the central Plaza de Armas in the border city of Pilar, according to police, who estimated their number at 400.
This is the first time that residents take to the streets to oppose the project.
The concern among the Paraguayan authorities and public opinion emerged in mid-February following statements by the Argentine Planning Minister Julio De Vido, who said that the uranium processing company Dioxitec be installed in Formosa, as reported by the Paraguayan Senate.

CNEA now considers relocation of Dioxitek UO2 plant from Córdoba to Formosa
Following a meeting between the Federal Planning Minister Julio De Vido and the mayor of Córdoba, Ramón Mestre, municipal sources said Dioxitek could settle in the province of Formosa. This is the uranium dioxide plant located in Alta Córdoba neighborhood.
The plant was shut down by the city last year, due to clearance problems. Then, the commitment of the Nation to move the plant by September this year was achieved.
However, less than three months after the deadline, the target of the factory is still uncertain.
So far, the strongest possibilities were Río Tercero and Embalse, but in both cases appeared neighborhood complaints and judicial measures, complicating the outlook for the relocation of Dioxitek.

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.

South Africa releases draft Nuclear Energy Policy and Strategy for public comment
On August 13, 2007, the Department of Minerals and Energy released its draft Nuclear Energy Policy and Strategy for public comment.
"Government, through Necsa, shall undertake and lead the
development of uranium conversion capabilities as part of the beneficiation of uranium. Private sector participation in the conversion process will be promoted."
> Download Nuclear Energy Policy and Strategy for the Republic of South Africa, Draft for Public Comment, July 2007 (231k PDF)
"Government, through Necsa, shall investigate the viability of developing its own uranium enrichment capabilities and will simultaneously actively seek to acquire established uranium enrichment technologies to ensure security of supply."
"Government, through Necsa shall design a strategy to develop nuclear fuel fabrication capabilities and will in the intervening period actively seek to obtain established fuel fabrication technologies to ensure security of supply."
Necsa to make a call on uranium enrichment:
The proposed expansion of South Africa's nuclear power generating capability to seven plants, as proposed in the Integrated Resource Plan, will be pivotal to a decision on whether uranium enrichment is resumed at the Pelindaba nuclear research centre.
A resumption will be needed to fuel the new power station fleet and make South Africa an exporter of enriched uranium. While questions remain over South Africa's ability to build the reactors, or fund and maintain them, the CEO of the SA Nuclear Energy Corporation (Necsa), Phumzile Tshelane, says the decision "is purely Necsa's" and will be determined by economics.
While one nuclear plant does not warrant uranium enrichment in South Africa, the game changes with a fleet of seven - Koeberg and the proposed six new ones.
However, the National Planning Commission has called for caution over the nuclear-build programme, and the National Energy Regulator of South Africa has told Parliament's energy committee that such a scheme could trigger further electricity price hikes.

South Africa is expected to begin enriching uranium by 2017, Nuclear Energy Corporation of South Africa CEO Rob Adam said on June 25, 2007.
"It could even be in five years, but definitely in ten years' time," he said.
South Africa, which dismantled its nuclear weapons programme during the 1990s, indicated in 2006 that it was considering enriching uranium for peaceful purposes.
However, Department of Minerals and Energy director-general Sandile Nogxina stressed that any uranium enrichment taking place in the country would be under government control.
A private company could have equity in an enriching initiative, but not a controlling stake, he said.

Heathgate Resources proposes to build uranium conversion plant at its Beverley uranium mine (South Australia)
Heathgate Resources wants to build a uranium conversion plant at its Beverley mine to add greater value to the raw material it mines at the site.
Heathgate would need State and Federal Government approval to build a conversion plant but has not raised the issue yet.
Heathgate Resources is owned by the giant American defence and nuclear group General Atomics.
General Atomics also owns 50 per cent of a uranium conversion company called ConverDyn , which has its head office in Colorado.
Heathgate president David Williams said if a conversion plant was to be built by Heathgate it would need to act as a centre for all Australian uranium miners to be economically viable.
Federal Resources Minister Martin Ferguson said the Government was opposed to the development of a nuclear power industry, other than uranium mining and milling.
