§ Mr. Sayeed
To ask the Secretary of State for Trade and Industry what estimate she has made of the cost of electricity generated by nuclear power in pence/kilowatt hour, broken down into(a) building costs, (b) running costs, (c) decommissioning costs on a discounted basis and (d) other costs, identifying the assumptions made; and if she will make a statement. 
§ Mr. Wilson
The Department has made no recent estimates of the cost of electricity generated by nuclear power. The last study published in 1995 concluded that the levelised costs of nuclear power were around 3.9p/kWh. Studies suggest that capital costs account for about 70 per cent. of total costs, operating and maintenance costs about 20 per cent. and decommissioning and waste costs about 10 per cent.
The Department is contributing to the work of the energy review being undertaken by the Performance and Innovation Unit at the Cabinet Office, which is looking at the cost of new nuclear generation. A copy of their paper which includes estimates of nuclear generation costs can be found at http://www.cabinet-office.gov.uk/innovation/2001/energy/2050.pdf.
§ Mr. Stunell
To ask the Secretary of State for Trade and Industry what was the(a) total amount of electricity generated from nuclear generators in the UK and (b) proportion of all electricity used in the UK generated from (i) nuclear generation and (ii) UK-based nuclear generation, since 1990.
