Uranium Imports: A critical dose to step up generation


The performance and success of India’s nuclear power generation hinges on the import of the fuel to a great extent. A steady supply of uranium is good news.
By the end of this calendar year, nearly 3,000 metric tonnes (MT) of nuclear fuel is likely to be shipped into India from three countries — the Russian Federation, Canada and the Republic of Kazakhstan. The uranium shipments expected in 2016 is a record for a single year and would, in quantitative terms, amount to nearly 53 per cent of total nuclear fuel imported into India since the country’s access to the global nuclear fuel market opened up in 2008.

Till now, about 5,559 MT has come into the country from these three nations, alongside France, while 2,937 MT is the anticipated supplies of nuclear fuel in the form of natural uranium ore concentrate and natural uranium oxide pellets during calendar year 2016. In India, there are currently 21 reactors with an installed capacity of 5,780 MWe (mega watt electrical), of which, eight reactors with aggregate capacity of 2,400 MWe are fuelled by indigenous uranium while the remaining 13 with a capacity of 3,380 MWe are under International Atomic Energy Agency (IAEA) Safeguards and use imported uranium. The second unit of the Kudankulam nuclear project (1,000 MWe Unit-2) has also attained first criticality (start of controlled self-sustaining nuclear fission chain reaction in the reactor for the first time) on July 10, 2016, which also uses imported fuel.

A steady supply of uranium is good news for the country’s nuclear power sector, something that is expected to push up the performance of Indian nuclear power plants, as well as of the several fuel cycle facilities. The capacity factor — or operational efficiency — of the 21 nuclear power reactors currently running in the country was recorded at 73 per cent in the first three months of the current fiscal (April-June 2016). This includes the operational data for the first unit of the Kudankulam power project.

An improvement in gross nuclear generation in the coming months could be powered by a combination of two factors: international cooperation leading to augmentation of fuel supplies to 13 reactors that qualify for imported fuel, and a commensurate improvement in domestic fuel supplies for the other eight. Under the “separation plan” announced by the government in March 2006, negotiated after the July 2005 nuclear deal with the US, India was required to bring 14 reactors under IAEA Safeguards in a phased manner. Thirteen of these reactors — including RAPS 2 to 6 at Rawatbhata, Rajasthan, KAPS 1 and 2 at Kakrapar, Gujarat, NAPS 1 and 2 at Narora, Uttar Pradesh, TAPS 1 and 2 at Tarapur, Maharashtra, Kudankulam 1 in Tamil Nadu — are already under IAEA safeguards, and eligible to run on imported fuel. They are now operating at close to full capacity, officials of Nuclear Power Corporation of India Ltd (NPCIL), which runs the country’s nuclear power plants, said. The other reactors — KGS 1 to 4 at Kaiga, Karnataka, MAPS 1 and 2 at Kalpakkam, Tamil Nadu, and TAPS 3 and 4 at Tarapur, Maharashtra — continue to use uranium sourced within the country.

Official sources said that the Department of Atomic Energy reckons the annual fuel need for operating the indigenous pressurised heavy water reactors (PHWRs) at 85 per cent capacity is about 45 tonnes of uranium dioxide for the older 220 MWe units, 100 tonnes for the 540 MWe units and 125 tonnes for the new 700 MWe units. By contrast, the need of low enriched uranium for operating imported light water reactors (LWRs) at 85 per cent capacity factor are six tonnes for the older 160 MWe Tarapur units and 27 tonnes for 1,000 MWe units such as the twin Russian-built VVER-1000 reactor units at Kudankulam.

The total installed capacity is scheduled to go up to 9,980 MWe at the end of the current five-year plan period (March 2017), as seven new reactors are commissioned. These include the imported LWRs of Russian design, four indigenous PHWRs, and one indigenous prototype fast breeder reactor (PFBR).

NPCIL had planned to start work on 16 new reactors with a total capacity of 16,100 MWe during the Twelfth Plan (2012-17). These included eight indigenous PHWRs of 700 MWe each with a total capacity of 5,600 MWe and eight LWRs based on international cooperation — with Russia, France and the US — totaling to a capacity of 10,500 MWe.

Those who have power to change things don't bother to;and those who bother don't have the power to do so .................but I think It is a very thin line that divides the two and I am walking on that.Well is pure human nature to think that "I am the best and my ideas unquestionable"...it is human EGO and sometimes it is very important for survival of the fittest and too much of it may attract trouble.Well here you decide where do I stand.I say what I feel.
