approval for these types of treatment systems. The feasibility of demineralization of brackish and saline waters is controlled
partly by the ability to dispose of the concentrated byproduct of demineralization. The disposal of concentrate by deep well
injection is potentially a solution; however, the corrosivity of the fluid and its compatibility with the steel tubing that is
typically used for such wells presents both technical and regulatory challenges. Therefore, this report was developed to assess
corrosion rates in deep injection wells that dispose of concentrate from the demineralization of brackish water and to identify
the well construction options available for the construction of these wells within SJRWMD.

This evaluation was performed by Pro2Serve in accordance with the Technical Specification for an Engineering
Evaluation of the Proposed Alternative Salt Transfer Method for the Molten Salt Reactor Experiment at the Oak Ridge
National Laboratory (BJC 2009b). The evaluators reviewed the Engineering Evaluation Work Plan for Molten Salt Reactor
Experiment Residual Salt Removal, Oak Ridge National Laboratory, Oak Ridge, Tennessee (DOE 2008). The Work Plan
(DOE 2008) involves installing a salt transfer probe and new drain line into the Fuel Drain Tanks and Fuel Flush Tank and
connecting them to the new salt transfer line at the drain tank cell shield. The probe is to be inserted through the tank ball valve
and the molten salt to the bottom of the tank. The tank would then be pressurized through the Reactive Gas Removal System
to force the salt into the salt canisters. The Evaluation Team reviewed the work plan, interviewed site personnel, reviewed
numerous documents on the Molten Salt Reactor (Sects. 7 and 8), and inspected the probes planned to be used for the transfer.
Based on several concerns identified during this review, the team recommends not proceeding with the salt transfer via the
proposed alternate salt transfer method. The major concerns identified during this evaluation are: (1) Structural integrity of the
tanks - The main concern is with the corrosion that occurred during the fluorination phase of the uranium removal process.
This may also apply to the salt transfer line for the Fuel Flush Tank. Corrosion Associated with Fluorination in the Oak Ridge
National Laboratory Fluoride Volatility Process (Litman 1961) shows that this problem is significant. (2) Continued generation
of Fluorine - Although the generation of Fluorine will be at a lower rate than experienced before the uranium removal, it will
continue to be generated. This needs to be taken into consideration regardless of what actions are taken with the salt. (3) More
than one phase of material - There are likely multiple phases of material in the salt (metal or compound), either suspended
through the salt matrix, layered in the bottom of the tank, or both. These phases may contribute to plugging during any planned
transfer. There is not enough data to know for sure. (4) Probe heat trace - The alternate transfer method does not include heat
tracing of the bottom of the probe. There is a concern that this may cool the salt and other phases of materials present enough
to block the flow of salt. (5) Stress-corrosion cracking - Additionally, there is a concern regarding moisture that may have been
introduced into the tanks. Due to time constraints, this concern was not validated. However, if moisture was introduced into
the tanks and not removed during heating the tanks before HF and F2 sparging, there would be an additional concern regarding
the potential for stress-corrosion cracking of the tank walls.

Electronic Structure of Transition Metal Clusters, Actinide Complexes and Their Reactivities
January 2009; 29 pp.; In English
Contract(s)/Grant(s): DE-FG02-04ER15546
Report No.(s): DE2010-959347; No Copyright; Avail.: National Technical Information Service (NTIS)
This is a continuing DOE-BES funded project on transition metal and actinide containing species, aimed at the electronic
structure and spectroscopy of transition metal and actinide containing species. While a long term connection of these species
is to catalysis and environmental management of high-level nuclear wastes, the immediate relevance is directly to other
DOE-BES funded experimental projects at DOE-National labs and universities. There are a number of ongoing gas-phase
spectroscopic studies of these species at various places, and our computational work has been inspired by these experimental
