arrangement with the National Academy of Sciences to conduct a study to determine—
“(i) the feasibility of procuring supplies of medical isotopes from commercial sources that do not use highly enriched uranium;
“(ii) the current and projected demand and availability of medical isotopes in regular current domestic use;
“(iii) the progress that is being made by the Department of Energy and others to eliminate all use of highly enriched uranium in reactor fuel, reactor targets, and medical isotope production facilities; and
“(iv) the potential cost differential in medical isotope production in the reactors and target processing facilities if the products were derived from production systems that do not involve fuels and targets with highly enriched uranium.
“(B) FEASIBILITY.—For the purpose of this subsection, the use of low enriched uranium to produce medical isotopes shall be determined to be feasible if—
“(i) low enriched uranium targets have been developed and demonstrated for use in the reactors and target processing facilities that produce significant quantities of medical isotopes to serve United States needs for such isotopes;
“(ii) sufficient quantities of medical isotopes are available from low enriched uranium targets and fuel to meet United States domestic needs; and
“(iii) the average anticipated total cost increase from production of medical isotopes in such facilities without use of highly enriched uranium is less than 10 percent.
“(C) REPORT BY THE SECRETARY.—Not later than 5 years after the date of enactment of the Energy Policy Act of 2005, the Secretary shall submit to Congress a report that—
“(i) contains the findings of the National Academy of Sciences made in the study under subparagraph (A); and
“(ii) discloses the existence of any commitments from commercial producers to provide domestic requirements for medical isotopes without use of highly enriched uranium consistent with the feasibility criteria described in subparagraph (B) not later than the date that is 4 years after the date of submission of the report.
“(5) SECOND REPORT TO CONGRESS.—If the study of theNational Academy of Sciences determines under paragraph
(4)(A)(i) that the procurement of supplies of medical isotopes from commercial sources that do not use highly enriched uranium
