[Nuclear Power] Stepping on a minefield
As nuclear waste maims people, India plans to generate more.
INDIA intends to increase the share of nuclear power from 3.1 per cent of its total energy generation to 25 per cent by 2050. Six nuclear power reactors are under construction and eight are in the pipeline. While the country plans to expand mining of uranium to feed the reactors, a yet-to-be-released study by the environmental group “Toxics Link” pointed out that it lacked knowledge about handling nuclear waste; the existing uranium mines do not follow requisite safety methods.
Most uranium is mined in Jadugoda in East Singhbum district and three other places in Jharkhand. The ore in Indian mines contains a low percentage (0.042-0.051 per cent) of the mineral, except in Meghalaya. The problem with low-grade ore is that extracting a small amount of concentrated uranium generates a large amount of waste. The ore grade is high in Meghalaya but an onslaught of rains makes the terrain almost inaccessible for six months in a year.
The Uranium Corporation of India Limited (UCIL) plans to invest about Rs 31 billion to set up new mines and processing plants in Jharkhand, Andhra Pradesh and Meghalaya as part of the eleventh plan. “The proposed mine at Kadapa in Andhra Pradesh involves extraction of 3,000 tonnes of uranium per day from underground mines spread over 879 hectares,” said the study done from August to November. Quoting members of the non-profit Mines, Minerals and People, the study said for a uranium concentration of 0.039 per cent, the waste to be disposed of would amount to nearly a million tonnes per year.

Current trends of Renewable Energy
Solar photovoltaics is the fastest growing area in the energy sector. Of the US $71 billion invested in renewables worldwide in 2007, 30 per cent was in solar PV. According to market analysts, between 2007 and 2011, this industry is poised to grow at a whopping 73 per cent. By March 2007, India had 120 mw of installed PV capacity. However, less than 2.5 MW is generated by grid-connected solar power plants. The rest is generated through stand-alone systems like solar street lighting (about 70,474), home lighting (4,02,938) and solar lanterns (6,70,059).
The government has several schemes supporting and subsidizing various kinds of solar power systems.The emphasis is on encouraging manufacturing and industry rather than on installations as solar PV manufacturing is capital intensive.
Through the special incentive package scheme, the government offers capital subsidies to state-of-the-art semiconductor manufacturing and related units, including solar PV. Eligible semiconductor “fab” projects must have a net present value of at least Rs 2,500 crore. The subsidy available is 25 per cent of the capital expenditure; it is 20 per cent for projects in a special economic zone. The response was good. “Most of the manufacturers who have applied under the scheme want to invest in photovoltaic technology. Proposals roughly worth Rs 1,40,000 crore from 14 manufacturers are lying with the ministry of which 12 are photovoltaic manufacturers” said K S Chari, director in the Union Ministry of Communications and Information Technology, the nodal ministry. Most of the proposals have been forwarded to a technical evaluation committee and decision is expected “shortly”. Continue reading »
