Tehran,Head of Iran’s atomic energy agency, Wednesday (21/4/2010) said the location for the construction of new facilities for uranium enrichment has not been decided.”Design for the location (enrichment) of the first new nuclear will be done this year,” said Ali Akbar Salehi told news agency ILNA.

“The location for a nuclear facility has not been decided. After presidential approval, the decision will be made regarding this matter.”On Monday, Mojtaba Hashemi Samareh, senior advisor to Ahmadinejad, says the president has approved the location for new nuclear facilities.Development in this location will start with commands him. But Hashemi also explained that the design of new facilities that are still studied.

In November 2009, Ahmadinejad announced Iran will build 10 new uranium enrichment facility after Tehran’s nuclear watchdog criticized the UN for building a second facility like that near the Shia holy city, Qom.Salehi, April said the plans of two new uranium enrichment plant has been presented to Ahmadinejad and construction will commence mid year and will run until March 2011.

Iran has started work on a new uranium enrichment nuclear plant, a senior official said on Monday, part of a big expansion of its nuclear program which has contributed to fears in the West it aims to build a bomb.Defying Western pressure to curb its sensitive nuclear work, Iran announced in November it planned to expand its enrichment activities by building 10 new sites. The announcement was condemned by the United states and its European allies.”The president has confirmed the designated location of a new nuclear site and on his order the building process has begun,” Mojtaba Samareh-Hashemi, a senior adviser to President Mahmoud Ahmadinejad, told the semi-official ILNA news agency.

“New locations on which the plants should be constructed this year have been determined and initial construction is underway,” Samareh-Hashemi was quoted as saying.Iran’s top nuclear official Akbar Salehi told Reuters in February that Iran would start construction of two enrichment sites by March 2011.Washington is pushing for a fourth round of United Nations sanctions on Iran in the coming weeks to pressure it to halt its enrichment-related work, which Tehran says is entirely peaceful.Iran started higher-level enrichment in February, saying it needed the 20 percent enriched fuel for a research reactor in Tehran making medical isotopes. Such potent material is not necessary to generate electricity.

Tehran has said it is still willing to swap low-level enriched uranium for higher-grade fuel enriched abroad — a move which would help address fears about Iran’s enrichment activities — but the exchange must happen on Iranian soil.The West believed it had persuaded Iran, at talks in Geneva last October, to hand over some of its uranium stocks to be enriched abroad, but that deal fell apart soon afterwards.Samareh-Hashemi said any import of enriched uranium would not mean Iran planned to stop its own enrichment.”The domestic production of (nuclear) fuel does not contradict importing it,” he said.

“We have started to produce uranium domestically based on our need to provide fuel for the Tehran research reactor and this will continue until our needs are met.”In a separate development, state-owned Jam-e-Jam daily said Iran’s ambassador to the U.N. International Atomic Energy Agency, Ali Asghar Soltanieh, would soon be stepping down as his term was coming to an end. Soltanieh was not immediately available to comment.(Reuters)

Mahmoud AhmadinejadTEHRAN,   Iran’s president has dismissed a year-end deadline set by the Obama administration for Tehran to accept a U.N.-drafted deal to swap enriched uranium for nuclear fuel.The deal aims to diminish Iran’s stockpile of enriched uranium, easing the West’s fears that the material could be used to produce a nuclear weapon. Iran, which denies it seeks to build a bomb, has balked at the deal’s terms.

Mahmoud Ahmadinejad says that “if Iran wanted to make a bomb, we would be brave enough to tell you.”He says the West can give Iran “as many deadlines as they want, we don’t care.”Ahmadinejad spoke on Tuesday to supporters in the southern city of Shiraz. He lashed out at Washington, saying Iran won’t allow the U.S. to dominate the region.

TEHRAN, Iran’s nuclear chief said Friday the country has started making more efficient centrifuge models that it plans to put in use by early 2011 – a statement that underscores Tehran’s defiance and adds to international concerns over its nuclear ambitions.The official, Vice President Ali Akbar Salehi, said Iranian scientists are still testing the more advanced models before they will become operational at the country’s enrichment facilities.Tehran has been saying since April that it is building more advanced centrifuges capable of enriching uranium with higher efficiency and precision, but Salehi’s remarks were the first indication of a timeline when the new models could become operational.

The new centrifuge models will be able to enrich uranium much faster than the old ones – which would add to growing concerns in the West because they would allow Tehran to accelerate the pace of its program. That would mean Iran could amass more material in a shorter space of time that could be turned into the fissile core of missiles, should Tehran choose to do so.

Iran’s uranium enrichment is a major concern to the international community, worried that the program masks efforts to make a nuclear weapon. Tehran insists its enrichment work is peaceful and only meant to generate electricity, not make an atomic bomb.

Iran has threatened to expand its enrichment program tenfold, even while rejecting a plan brokered by the U.N. nuclear watchdog agency to supply fuel for Iran’s research reactor if Tehran exports most of its enriched stockpile. The U.N. plan would leave Iran – at least temporarily – without enough uranium to produce a bomb.

Centrifuges are machines used to enrich uranium – a technology that can produce fuel for power plants or materials for a nuclear weapon. Uranium enriched to low level is used to produce fuel but further enrichment makes it suitable for use in building nuclear arms.

“We are currently producing new generation of centrifuges named IR3 and IR4,” Salehi told the semiofficial Fars news agency. “We hope to use them by early 2011 after resolving problems and defects.”He did not elaborate on the technical details or the difference between various centrifuge types.However, Salehi added: “We are not in a rush to enter the industrial-scale production stage.”

The new centrifuges would likely replace the decades-old P-1 centrifuges, once acquired on the black market and in use at Iran’s main uranium enrichment facility in Natanz, central Iran.

Iran has said the new centrifuges would also be installed at Iran’s recently revealed secret uranium enrichment facility. The plant is still under construction at Fordo, near the holy city of Qom.

Salehi said that more than 6,000 centrifuges are currently enriching uranium – 2,000 more than the figure mentioned in a November report by the U.N. watchdog, the Vienna-based International Atomic Energy Agency.

The IAEA has reported that it is watching Iran’s efforts to improve its centrifuges.Iran says it will install more than 50,000 centrifuges at Natanz, but currently they have installed fewer than 9,000, so there could easily be room for more advanced models in the future, a Vienna nuclear expert said. The expert spoke on condition of anonymity because of the sensitivity of the issue.

Iranian officials have claimed that most parts for the new centrifuges are made domestically and others have been imported – a sign that Iran was able to get around U.N. sanctions imposed on the country for its refusal to suspend uranium enrichment.Iran’s defiance has not wavered amid recent signals of possible more U.N. sanctions over its enrichment. Salehi said Friday such new sanctions won’t stop Iran from developing its nuclear program.

“We don’t welcome new (U.N. Security Council) resolutions,” he told ISNA, another semiofficial news agency. “But resolutions won’t stop us in any field, including the nuclear.”

MANAMA, Bahrain  Iran is ready to exchange the bulk of its stockpile of enriched uranium for nuclear fuel rods – as proposed by the U.N. – but according to its own mechanisms and timetable, the foreign minister said Saturday.The minister’s remarks come just days before an expected meeting between the U.S. and allies to discuss new sanctions against Iran over its nuclear program. The offer, however, falls far short of the conditions set by the international community.Speaking to reporters at a regional security conference in Bahrain, Manochehr Mottaki said Iran agreed with a U.N. deal proposed in October in which up to 2,600 pounds (1,200 kilograms) of its uranium would be exchanged for fuel rods to power its research reactor.


“We accepted the proposal in principle,” he said through a translator. “We suggested in the first phase we give you 400 kilograms of 3.5 percent enriched uranium and you give us the equivalent in 20 percent uranium.”Iran has about 3,300 pounds (1,500 kilograms) of low-enriched uranium and needs to refine to 20 percent to operate a research reactor that produces medical isotopes.

Uranium enriched at low levels can be used as fuel for nuclear energy, but when enriched to 90 percent and above, it can be used as material for a weapon. The United States and five other world powers have been trying to win Iran’s acceptance of a deal under which Tehran would ship most of its low-enriched uranium stockpile abroad to be processed into fuel rods, which can’t be enriched further.

The deal would leave Iran – at least temporarily – without enough enriched uranium to produce a bomb. However, after signaling in October that it would accept the proposal, Iran has since balked, giving mixed signals over the deal, including several statements from lawmakers rejecting it outright.Mottaki maintained, however, that a clear proposal had been given involving the simultaneous exchange of uranium for fuel rods in stages.”We gave a clear answer and we responded and our answer was we accepted in principle but there were differences in the mechanism,” he said, suggesting the exchange take place on Iran’s Kish island, in the Persian Gulf.

It is not clear, however, if the low-enriched uranium would then remain on the island or could be shipped out of the country – a necessary condition to any deal from the standpoint of the international community.The world powers are also unlikely to accept a long drawn out exchange in stages, as it would allow Iran to maintain enough enriched uranium inside the country to possibly build a weapon.Iran, meanwhile, wants to receive the fuel rods immediately in exchange for its uranium for fear that France or Russia could renege deal.

Last month, the 35-nation board of the International Atomic Energy Agency endorsed a resolution from the six powers – the U.S., Russia, China, Britain, France and Germany – criticizing Iran for defying a U.N. Security Council ban on uranium enrichment and continuing to expand its operations.It also censured Iran for secretly building a second facility and demanded that it immediately suspend further construction.

British Prime Minister Gordon Brown said last month that the U.N. offer has been “comprehensively rejected” by Iran. A diplomat from one of the six powers said Wednesday that America’s Western allies were waiting for Washington to formally declare the wait for an Iranian response over, probably by the end of this month.The six countries are expected to meet next week to discuss what action to take over Iran.EU leaders said they would support further U.N. sanctions unless Tehran starts cooperating over its nuclear program.

Iran’s foreign minister says the country is ready to swap up to 2,600 pounds (1,200 kilograms of its enriched uranium for nuclear fuel rods), as proposed by the U.N. nuclear watchdog.

Manochehr Mottaki told reporters in Bahrain Saturday that Iran suggested exchanging 880 pounds (400 kilograms) of its enriched uranium on Kish island in the initial phase.

The International Atomic Energy Agency proposed in October Iran ship out its 3.5 percent enriched uranium to be further refined by France and Russia into fuel rods for a research reactor.

The U.S. and its allies fear Iran’s nuclear program is aimed at making a bomb, while Tehran maintains it’s for peaceful purposes.Mottaki said Iran agreed with the deal in principle, there were only differences over the mechanisms of the swap.

The Colorado Department of Public Health and Environment (CDPHE) received the radioactive materials license application and environmental report from Energy Fuels on 18 November. The application will undergo a comprehensive technical review process including technical evaluations, a review of the environmental report and two public hearings. Public comments will also be accepted throughout the review process, which Colorado law stipulates must take no more than 14 months. Energy Fuels has previously mentioned the possibility of starting construction of the mill by the second quarter of 2011.

Steve Tarlton, radiation program manager for CDPHE, said the review would consider short- and long-term impacts of the proposed mill, including radiological and non-radiological impacts to water, air and wildlife, as well as economic, social and transportation-related impacts. “Our job is to ensure that the licence, if approved, will protect public health and the environment,” he said.Energy Fuels plans to build the Pinon Ridge mill near Naturita on land that it bought in 2007. The 500 tonnes per day mill would be the first new uranium mill to be built in the USA in over a quarter of a century. Energy Fuels president and CEO George Glassier said he was confident that the “thorough and accurate” license application would meet all CDPHE’s regulations. “In progressing to this final stage of approvals, Energy Fuels is clearly moving forward on its plan to construct the first new uranium mill in the US in more than 25 years,” he said.

Energy Fuels Resources Corp is part of Toronto-based Energy Fuels Inc, which has a portfolio of uranium and vanadium properties in Colorado, Utah, Arizona, Wyoming, Idaho and New Mexico, as well as Canadian exploration properties in Saskatchewan’s Athabasca Basin. The company has been working to refurbish and reopen some of its formerly producing mines, including former uranium-vanadium mines in the Urania mineral belt in western Colorado. Energy Fuels has near-term uranium projects at Whirlwind and Tenderfoot Mesa in Colorado and also at nearby Energy Queen in Utah. Although permitted to restart, the company placed the Whirlwind project on standby in late 2008 as part of a “capital preservation strategy”, although the company said at the time it would be maintained in a state of readiness to ramp up to full production at 30 days’ notice.

Powertech queries groundwater rules

Meanwhile, another would-be Colorado uranium producer has queried the legality of proposed state rules on groundwater protection. According to press reports, Power-tech USA says that proposed rules on groundwater quality and reclamation forming part of legislation on  leach mining are currently too broad. A specific issue of concern is the proposed requirement for a “baseline” for water quality, defined before mining began, which would become the standard for future reclamation, with no scope to revise the requirements at a later date.The Colorado Division of Reclamation, Mining and Safety is due to hold a public meeting on the rules in early December.
