Chapter 20 - A Cost/Benefit Perspective of Extended Unit Service as a Decommissioning Alternative

James G. Hewlett

The Energy Journal, 1991, vol. Volume 12, issue Special Issue, 255-272

Abstract: Some people consider life extension (and its cousin, license renewal) an alternative to decommissioning. The reasons for the popularity of such alternatives include presumed cost effectiveness, retention of scarce power plant sites, and the continued ability to pass on waste storage expenses as a cost of service. In this chapter, James Hewlett addresses nuclear power plant life extension- -which he calls NUPLEX--in its economic garb, starting with a look at the common utility presumption that life extension of a nuclear plant will allow it to produce electricity at a lower rate than new coal generation. This presumption, he argues, may not be supportable by analysis. He concludes that the deferral of constructing new replacement capacity would result in cost savings only if both the level and escalation rate of the operating costs for the refurbished unit fall substantially from 1986 levels. Therefore, it is unclear whether the deferral of the construction of new capacity would result in the cost savings, although it definitely shifts the financial burden into the future.
