India is expanding a covert uranium enrichment plant that could potentially support the development of thermonuclear weapons, a defence research group said on Friday, raising the stakes in an arms race with China and Pakistan.
The revelation highlights a lack of nuclear safeguards on India under new Prime Minister Narendra Modi, while sanctions-bound Iran faces minute scrutiny in talks with world powers over its own nuclear programme.
New units at the Indian Rare Metals Plant would increase India’s ability to produce weapons-grade uranium to twice the amount needed for its planned nuclear-powered submarine fleet, IHS Jane’s said.
The facility, located near Mysore in southern India, could be operational by mid-2015, the research group said, basing its findings on analysis of satellite imagery and public statements by Indian officials.
“Taking into account all the enriched uranium likely to be needed by the Indian nuclear submarine fleet, there is likely to be a significant excess,” Matthew Clements, editor of IHS Jane’s Intelligence Review said.
“One potential use of this would be for the development of thermonuclear weapons.” No comment was available from the Indian government press office or the foreign ministry.
Unlike Iran, India is not a signatory to the nuclear Non-Proliferation Treaty. New Delhi tested its first nuclear weapon in 1974, provoking international sanctions that barred it from importing nuclear technology and materials.
It conducted tests again in 1998 that drew a quick response from Pakistan, triggering an arms race between the neighbours, who have fought three wars since independence in 1947.
A civil nuclear cooperation deal with the United States, sealed in 2008, gave India access to know-how and fuel in return for a pledge – so far unfulfilled – to bring in U.S. firms to expand India’s nuclear power generation capacity.
The pact exempts military facilities and stockpiles of nuclear fuel from scrutiny by the International Atomic Energy Agency, a United Nations watchdog. The Mysore plant is not subject to IAEA safeguards.
The exemption, granted by the administration of President George W. Bush, faced opposition from China and Pakistan, India’s regional rivals, and European nations who said it would undermine efforts to control the spread of nuclear weapons.
Based on its analysis of commercial satellite images, IHS Jane’s has identified what appears to be a new uranium hexafluoride plant that would increase the uranium enrichment capacity of the Mysore facility.
The plant would be able to produce a surplus of around 160 kilos a year of uranium enriched to 90 percent purity, IHS Jane’s reckons. That is roughly double the needs of the nuclear submarine fleet India is developing to supplement its land-based missile arsenal – and enough to make five atomic bombs.
By blending the uranium with its existing stock of plutonium, India could develop thermonuclear weapons that have a complex detonation process and have a bigger impact than simpler weapons.
“We aren’t suggesting that this action alone will create an immediate standoff, but it’s going to create a further level of complexity in an already difficult situation,” said Clements, referring to the regional security implications.
The IHS findings have been corroborated by other analysts, with the Stockholm International Peace Research Institute (SIPRI) writing this week that the Mysore facility could signify India’s intent to move towards thermonuclear weapons.
India is estimated by SIPRI to hold 90 to 110 nuclear weapons in its arsenal.
The IHS assessment revealed incremental progress at Mysore since the Washington-based Institute for Science and International Security (ISIS), in a report last December, identified the construction of a new gas centrifuge plant.
India’s new Arihant class of submarine is assessed to have an 80-megawatt onboard reactor that contains around 65kg of uranium. One submarine is operational, a second is being built and a third is planned, according to ISIS.
No first use
Modi, leader of the nationalist Bharatiya Janata Party, has sought to assert New Delhi’s regional leadership in his first weeks in office while seeking to engage with major powers such as the United States and China.
But, although he invited Pakistan’s prime minister to his inauguration, Modi has made clear that any rapprochement would require a halt to occasional military clashes on the de facto frontier of the disputed Himalayan region of Kashmir.
Before Modi’s landslide general election victory last month, sources close to his party had suggested India might abandon its ‘no first use’ nuclear doctrine, which committed it to refrain from any pre-emptive strike.
Modi later denied any planned shift and vowed to uphold ‘no first use’, a signature policy of India’s last BJP prime minister, Atal Bihari Vajpayee, who ordered the 1998 nuclear tests.
