While many basic fuel performance requirements are the same for fossil and nuclear power plants, in the latter, additional performance re-requirements must be considered, e.g., the computation of fuel cost complicated by relatively long energy extraction time and energy variations between core areas, the necessity for fuel management, the increased complexity of fuel design and procurement, the need for shipment and reprocessing of radioactive spent fuel, and the large degree of government control over fuel. Therefore, the utility-oriented view of fuel performance requirements for water reactors recognizes nuclear fuel as high-precision equipment with complex lifetime characteristics and very high capital value.
