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.

Wave propagation of low-void-fraction, two-phase bubbly flow is analyzed from the compressibility of a bubble and an assumption of homogeneity for steam bubbles. The phase velocity and attenuation calculated from the model are strongly dependent on frequency. The equilibrium sound velocity is derived for the limiting case as frequency approaches zero. The second resonance of a vapor bubble is also discussed. In addition, the void fraction, bubble size, and noncondens-able gas effects are also analyzed in the model. The relationship between sound velocity and interfacial area density is derived, and a new method to measure interfacial area is proposed.
