SMALL NUCLEAR POWER PLANTS VOLUME TWO The Industrial Expression of Supply and Demand Considerations

摘要

At the time this study began, the prospect of economic power from nuclear power plants of less than 100 MWe appeared unpromising. However, the manufacturers have reappraised the economics of prospective concepts on the basis of multiple orders for identical plants and potential fuel cost improvements. Projected cost reductions are reported that can be used to forecast bus bar energy costs as low as 3.48 mills/kw-hr in a 100 MWe plant and 4.64 mills/kw-hr for 50 MW sizes. Similarly competitive costs have not been forecast for units smaller than 50 MW. For these, improvements other than sales volume would be required. Fully automatic operation of the smaller nuclear plants offers the possibility of providing staff costs commensurate with plant size. Examination of the prospects for automation indicates technical feasibility but suitable design is yet to be developed. Joint procurement of fuel, fuel reprocessing, maintenance, and expert services offer means of reducing OM costs. Fuel suppliers are willing to arrange com¬plete fuel management services if sufficient interest is expressed. In some regions, savings may be afforded by a multiple product plant if applicable. As a result, it appears that small nuclear power plants may be rendered economically feasible under some existing utility situations.
