TEAMER: Technical Support for Aquantis (Materials): CRD-21-17762-0

The Aquantis Tidal Power Tug is a unique synthesis of best-available technologies and materials configured as a novel spar vessel to create an optimal platform for tidal stream energy conversion. The Power Tug utilizes an upstream-facing horizontal, 2-bladed rotor. To drive down capital costs and extend the life of the Power Tug, Aquantis proposes to employ new materials for the blades that are both less expensive than current state-of-the-art materials and are potentially better suited for survival in a submerged, seawater environment. This project provided technical assistance by evaluating mechanical properties of a novel geopolymer material for application in tidal stream energy conversion systems. Coupons from a novel geopolymer material were tested in a load frame to characterize material properties. 

This work established characteristic properties of a geopolymer material under dry and saturated conditions through material coupon testing. Material coupons were tested to characterize properties including: a) tensile strength, b) compression strength, c) flexural strength, d) modulus of elasticity, and e) fatigue strength at varying load levels. The types of material tests performed were guided by the characteristics required to validate material properties for use in full-scale structures. This characterization of material properties while considering the demands of a full-scale structure is a necessary step in research and development that can enable the use of geopolymer materials in tidal stream energy conversion systems. 

This submission includes:
- a ReadMe file describing the contents and subfile organization of the coupon testing data .zip file 
- geopolymer coupon testing data including photos of testing set-ups, raw data, and summaries of flexural testing, compression testing, confined compression testing, and tensile and shear testing

Load Cap & Dil HNO3 Rinse of DGA Resin for Recov of TPEs & REEs from M-18A Targets

"Loading Capacity and Dilute Nitric Acid Rinse of Diglycolamide Resin for the Recovery of Transplutonium and Rare Earth Elements from Mark-18A Targets"

N,N,N′,N′-tetraoctyldiglycolamide (TODGA) as a resin (“DGA resin”) produced by Eichrom Technologies will be used by Savannah River National Laboratory for the extraction of trivalent actinides and rare earth elements with the intent of recovering Cm and Am from dissolved irradiated 242Pu Mark-18A targets in 7 to 9 M nitric acid. The extracted constituents will be recovered as an oxide by direct thermal decomposition of the loaded resin followed by calcination of the resultant residue. The characteristics of DGA resin with non-radiological feed simulant representative of the anticipated feed in the Mark-18A process, with Sm and Nd as surrogates for Cm and Am, respectively, including breakthrough point and saturation capacity were evaluated in this work. Additionally, this work examined the losses from the loaded resin by rinsing the resin bed with dilute acid to reduce the nitrate concentration in the resin bed prior to thermal decomposition operations to improve the safety posture of the process. A resin loading profile was developed, and the resin was determined to have a trivalent metal saturation capacity of 74 μmol/mL resin under the experimental conditions evaluated. Following a wash of the loaded resin bed with fresh 8 M HNO3, the trivalent metals retained were reduced to 68 μmol/mL resin, which represents the practical capacity of the resin for the Mark-18A process. Lighter lanthanides breakthrough the resin well before the saturation capacity is reached. Rinsing the saturated resin bed with 0.26 M HNO3 was found to result in a rapid reduction in retention of rare earth elements by the resin. After 2.8 bed volumes of dilute acid rinse, the mean resin bed free acid concentration was reduced to 0.28 M and 3.1 bed volumes of dilute acid rinse resulted in a reduction of the cumulative rare earth element retention to 52 μmol/mL of resin.

Catalytic Effects of Silver in Iodine Reactors for Dissolved Used Nuclear Fuel

The dissolution of used nuclear fuel generates a variety of off-gasses including flammable hydrogen and other species that are a concern for environmental release. The H-Canyon facility at the Savannah River Site is currently dissolving aluminum-clad research reactor fuel from material test reactors and the High Flux Isotope Reactor (HFIR) using a mercury-catalyzed nitric acid flowsheet. Savannah River National Laboratory recently developed and deployed a Raman spectrometer to monitor the off-gas stream from the dissolution process. Results from these measurements indicated a lack of the expected hydrogen, nitrous oxide, and nitric oxide in the off-gas stream. It was proposed that the silver on the silver nitrate–coated berl saddles present in the reactors for iodine capture were acting as a catalytic hydrogen recombiner. Nitric oxide is readily oxidized to nitrogen dioxide under normal conditions, but it was unclear what happened to the nitrous oxide. A laboratory-scale iodine reactor was assembled and filled with silver nitrate–coated berl saddles to help ascertain the fate of nitrous oxide and hydrogen. Testing with this laboratory-scale reactor observed the recombination of hydrogen when a simulated dissolver off-gas was passed through the reactor containing silver nitrate–coated berl saddles at the approximate temperatures seen in H-Canyon. However, the nitrous oxide concentration was unchanged, suggesting a more complex process occurring within the off-gas stream before it reaches the iodine reactors at H-Canyon.

Real-time infrared spectroscopy with blind source separation for nuclear waste process monitoring

On-line infrared absorbance spectroscopy enables rapid measurement of solution-phase molecular species. Many spectra-to-concentration models exist for spectral data, with some models able to handle overlapping spectral bands and nonlinearities. However, model accuracy is limited by the quality of training data used in model fitting. The process spectra of nuclear waste simulants at the Savannah River Site display incongruity between training and process spectra; the glycolate spectral signature in the training data does not match the glycolate signature in Savannah River National Laboratory process data. A novel blind source separation algorithm is proposed that preprocesses spectral data so that process spectra more closely resemble training spectra, thereby improving model quantification accuracy when unexpected sources of variation appear in process spectra. The novel blind source separation preprocessing algorithm is shown to improve nitrate quantification from an R2 of 0.934 to 0.988 and from 0.267 to 0.978 in two instances analyzing nuclear waste simulants from the Slurry Receipt Adjustment Tank and Slurry Mix Evaporator cycle at the Savannah River Site.

On the microstructure evolution of AA6061 with pulsed laser powder bed fusion

"This study uncovers new opportunities for microstructure engineering of AA6061 using pulsed lasers in powder bed fusion. Experimental analysis reveals that pulsed lasers allow for extensive control of grain sizes. Lower frequencies or duty cycles induce remelting cycles that promote finer grains and homogenized subgrain structures, while higher frequencies with high duty cycles sustain elevated temperatures, reducing cooling rates and resulting in coarser grains. Pulsing strategy is demonstrated as facile route for tailoring microstructure through enhanced control over solidification. These findings present an effective means in additive manufacturing by linking pulsed laser dynamics to microstructure evolution towards desired material properties.

This study unveils effective grain structure control using pulsed lasers without alloy modification, achieving texture homogenization and uniform subgrain structure through multiple melt pool boundaries."

GC-MS Screening Data for Instrument Optimization

The objective of this example case was to maximize peak height and minimize peak width of 11 iodinated standards analyzed using gas chromatography-mass spectrometry (GC-MS). Seven parameters (split ratio, carrier gas flow rate, inlet temperature, injection volume, auxiliary line temperature, oven temperature ramp rate, and capillary column film thickness) were chosen due to their known impact on GC−MS performance metrics (i.e., minimized peak width and maximized peak height) optimized in this study. To limit the number of experiments required for the surface response experiments, screening experiments were performed to determine the statistically significant parameters. A two-level fractional factorial design was created with 32 distinct observations (methods) with a resolution of 4 and a defining aliasing pattern of ABCF = CDEFG = I. The data was collected using an Agilent GC-MS (7890 GC, 7010C mass spectrometer, Agilent Technologies, Santa Clara, CA) operated in full scan mode. Chromatographic separation was performed using a Restek Rtx-1701 GC column (30 m × 0.25 mm ID; Restek Corporation, Bellefonte, PA). The source temperature was held at 230 °C and the quadrupoles were held at 150 °C. An emission current of 100 μA and ionization energy of 70 eV were used. The oven temperature program was held at 35 °C for 5 minutes and then increased at the chosen oven temperature ramp rate to 280 °C and held for 15 minutes. The attached CSV files contain the fractional factorial design (ffd.csv), the raw chromatographic data for the 32 distinct methods (TIC_Method_#.csv), and the retention times (rts.csv) for each iodinated standard.

GC-MS Surface Response Data for Instrument Optimization

The objective of this example case was to maximize peak height and minimize peak width of 11 iodinated standards analyzed using gas chromatography-mass spectrometry (GC-MS). Once the significant (or most significant) parameters have been determined in a prior screening experiment, another set of experiments must be designed in which a response surface objective experiment is performed to collect data for optimization. In this example case, surface response experiments were performed using a 3-level Box-Behnken design in which each statistically significant parameter (e.g. split ratio, carrier gas flow rate, oven temperature ramp rate, and capillary column film thickness) was assigned a “low”, “middle”, and “high” value. For these experiments, the three nonsignificant parameters, inlet temperature, injection volume, and auxiliary line temperature, were fixed at 200 °C, 2 μL, and 280 °C, respectively. The experiments were conducted in the same manner as described in the screening experiments section. The attached CSV files contain the Box-Behnken design (bbd.csv), the raw chromatographic data for the 25 distinct methods (Method #.csv), and the retention times (bb_rts.csv) for each iodinated standard.
