INL’s new innovation incubator could link start-ups with an industry sponsor
Idaho National Laboratory is looking for a sponsor to invest $5 million–$10 million in a privately funded innovation incubator to support seed-stage start-ups working in nuclear energy, integrated energy systems, cybersecurity, or advanced materials. For their investment, the sponsor gets access to what INL calls “a turnkey source of cutting-edge American innovation.” Not only are technologies supported by the program “substantially de-risked” by going through technical review and development at a national laboratory, but the arrangement “adds credibility, goodwill, and visibility to the private sector sponsor’s investments,” according to INL.

In solvent extraction for nuclear fuel reprocessing, a stable emulsion called “crud” is formed at the interface between the organic and aqueous phases. Crud is an emulsion stabilized by finely dispersed solids. Process disturbances are often induced by crud. Accordingly, crud should be eliminated from the interface in the extractors. The eliminated crud is stable and highly radioactive; thus, the treatment of this crud may be difficult. Complexes of zirconium and tributyl phosphate (TBP) degradation products, such as phosphoric acid (H3PO4) and mono-n-butyl phosphate (H2MBP), are one source of the fine particles that stabilize emulsions in the extraction process. A chemical treatment method to demulsify crud stabilized by precipitates of Zr-H3PO4 and Zr-H2MBP is studied. Experimental results indicate that neutralization by an alkaline solution, particularly sodium carbonate, is very effective for the destruction of this crud.
