My $25000/kg of uranium is the cost/kg at which uranium generated
electricity increases in cost by *1* cent/kwh.

wrong.. more like 77.5 cents per kWh.. not including enrichment,
construction, operational, and decommissioning costs..

math..

Initial fuel load 1GWe .. 100 metric tons of enriched UO2
before enrichment.. ~660 metric tons of U3O8(yellow cake)..
two refuelings, replacing 1/3 of fuel rods every 1.5 years
220 tonns * 2....

660MT + 220MT + 220MT == 1100 MT
1.5 years * 3 == 4.5 years @ 90% duty cycle..

1100 * 1000MT/kg * 25,000$/kg == 2.75e+10 dollars.. (27.5 Billion
dollars)

2.75e+10 / (4.5 years * 365.25 * 24 * .9 * 1,000,000(kWh/hr)) == 0.775
dollars per kWh or 77.5 cents per kWh in U3O8 costs..

Thorium per 1 GW Year: 6 lbs a day. Amount of waste per 1 GW year: 1
ton.

And that relatively cheap tonne/year of Th waste is pretty harmless
stuff compared to the spendy and highly toxic uranium alternative.
