38. PNNL SA-48454 Iran_Altenergy_PNWCGS_Feb1306.ppt Conclusions of Analysis Iran’s uranium resource is not commensurate with the scale of its declared nuclear program. Cost of indigenous uranium and fuel production appear substantially greater than market sources. Front-end (uranium and fuel facilities) do not provide independence. Indigenous non-nuclear energy resources represent centuries of potential energy supply at current R/P ratios. Cost of selected front-end nuclear facilities is at least $600 million dollars.

39. PNNL SA-48454 Iran_Altenergy_PNWCGS_Feb1306.ppt Conclusions of Analysis (2) Several plausible gas sector projects could be pursued for the cost of the front–end nuclear facility investment. Gas sector projects involving natural gas treatment plants, CCGT power plants, and supporting pipeline show very attractive rates of return at 18% (23%) over 30 years and a 4.6 (3.2) year payback periods. Projects which add refinery capacity increase refined product exports, generating billion dollars per year in net revenue. Approximating the gasoline yield fraction of Iran results in a more attractive refinery project assuming all additional refined products can be exported.
