Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

Several empirical equations were available in the literature for density equation for tri-n-butyl phosphate (TBP)–bearing mixed organic solutions used in the PUREX/UREX process; however, all most all of the equations were found to have a limited range and a limited number of solutes to be handled. In this work, a robust density equation is proposed in a dimensionally consistent manner. In the proposed equation, TBP is also considered as a solute, rendering the proposed equation valid over a full range of TBP concentrations. The highlights of this technical note include1. Density equation for mixed organic solutions, containing TBP, n-dodecane, and nitrates of heavy metals, is proposed in a dimensionally consistent manner.2. TBP is also considered as a solute, rendering proposed equation valid over 0% to 100% of TBP concentrations.3. The proposed equation is valid for uranium concentrations 0 to 120 g/L in organic phase.4. With a small loss of precision, the same can be used for PUREX solvent loaded with Pu(IV).
