Energy Fuels and Uranerz to Create the Largest Integrated Uranium Producer Focused on the United States

Quote:
Energy Fuels is currently well-positioned as the 2nd largest supplier of uranium within the U.S. It currently accounts for about 20% of U.S. uranium production from its wholly-owned White Mesa uranium mill, the only licensed and operating conventional uranium mill in the U.S. Uranerz is the newest uranium producer in the U.S., located in one of the most prolific areas of uranium production in the U.S. Uranerz recently commenced production at its Nichols Ranch ISR Uranium Project and holds one of the largest prospective land positions for ISR-amenable deposits in Wyoming. The Company will have a combined ISR and conventional asset base, unique in its scope and scalability, extending from the ISR-amenable Powder River Basin of Wyoming (the "Basin") to the conventional uranium mining districts of New Mexico, Colorado, Utah and Arizona.

Why cant the Americans use up thie stocks of fissile materials after blending it wit

Even the MOX plan is languishing.

We Americans can and will. NEIMA for advanced nuclear is needed and is presently in committee. Congress must act with the President. There are designs for burning SNF that require modernization of nuclear regulations here to begin the licensing and deployment of such designs. H.R. 4979 and S. 2795 were introduced in April and there's other legislation that will help companies test designs.

Sidenote: Posted on the Lithium-7 topic, so reply there, please:

jagdish, A few days ago on May 20, 2016, Jim L started "Article advocating U.S. nuclear power" and I mentioned at one point the HD lithium problem.
Jim L. wrote:
. . . there was a post about a different process that looked promising. That process is titled: "Green and efficient extraction strategy to lithium isotope separation with double ionic liquids as the medium and ionic associated agent" in case you need to search for it, not sure if it was posted in this forum. Feel free to jump into the discussions on it!

The paper is here: Journal of Radioanalytical and Nuclear Chemistry March 2013, Volume 295, Issue 3, pp 2103-2110.
Xu Jingjing, et al. wrote:
The single-stage isotope separation factor of 7Li–6Li was up to 1.023 +/- 0.002, indicating that 7Li was concentrated in organic phase and 6Li was concentrated in aqueous phase. All chemical reagents used can be well recycled. The extraction strategy offers green nature, low product cost, high efficiency and good application prospect to lithium isotope separation.

Another more recent paper is here: Journal of Nuclear Science and Technology Volume 52, Issue 3, 2015. It describes liquid-liquid extraction for lithium isotope separation based on room-temperature ILs containg 2,2'-binaphthyldiyl-17-crown-5.
Received: 4 Mar 2014, Xiao-Li Suna, et al. wrote:
Under optimized conditions, the maximum single-stage separation factor alpha of 6Li/7Li obtained in the present study was 1.046 +/- 0.002, indicating the lighter isotope 6Li was enriched in IL phase while the heavier isotope 7Li was concentrated in the solution phase.

According to the Preface to the text from 2014 Ionic Liquids in Separation Technology, ionic liquids (ILs) are an emerging technology that "has blossomed only within in the last decade."

I read Jingjing, et al. last night. What are the costs of these materials? If commercial implementation of IL techniques is underway because of a strong business case for HD lithium, then details will be cloaked under IP. But that would be a good thing. And it would indicate that 99.995% 7Li or better is commercially achievable.

I wonder if the B&P Process Equipment and Systems POD Liquid/Liquid Extraction Centrifuge (cheesy video music) would work for IL continuous counter-current 6Li/7Li separation?
