Use the following reference below to solve ab and c using the image to guide the problem.
For a reference LWR: assume a thermal efficiency is power MWe, uranium is $lb UO SWU is $kgSWU conversion is $kgU fabrication costs are $kgU losses in conversion losses in fabrication tails assay of wt reference core contains tonne fuel with enrichment of An average economical grade of uranium ore is Each fuel assembly contains
kg of fuel. The reactor operates on a batch equilibrium cycle of months which includes months at power including day startup and day for shutdown.
Evaluate an enriched UO fuel for the reference LWR:
a What would be the cost per kg of the fabricated UO fuel?
b Now, considering the time value of money, calculate the cost of the fuel $kgand the cost of a fuel reload to the point it is loaded in the reactor for operation assuming you purchase in advance: uranium months, conversion months, enrichment months, and fabrication services months.
c Accepting the US resource data Identified Resources: tonnes RAR and tonnes IR from the OECD Red Book, how long could you fuel the current reactors in the US Assume each has the same parameters as the reference LWR Be sure to clearly state the resource values you are referencing in this calculation and provide the reference.
