The Economics of the Nuclear Fuel Cycle (1994)

In early 1991, an expert group, with a membership drawn from fourteen countries and four international organisations, was formed to examine the economics of the fuel cycle with particular reference to a power station comprising a pressurised water reactor (PWR) commissioning in the year 2000. The expert group finalised its report at the end of 1993. The task of the expert group was to update the OECD/NEA 1983/84 study which was published in 1985. That study defined the levelised lifetime fuel cycle cost using internationally accepted investment appraisal methodology. Costs were derived for fuel cycles based on reprocessing and on long-term spent fuel storage followed by direct disposal. The current study repeats that approach. Use of a 5 per cent reference case discount rate is still considered appropriate in reflecting the consensus of national practices. It also enables direct comparison to be made with previous results. Variations due to the use of different discount rates are also given.
