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.

Past studies of wavelet technologies for gamma spectral analysis essentially focused on direct fitting of raw gamma spectra, but these studies often failed to produce new benefits for operational adaptation of wavelet analysis. This paper presents a modified wavelet approach with the objective being detecting only the nuclides that do not exist in the environmental background. With this operational objective, wavelet analysis is applied to the background-subtracted count-rate spectra. A preliminary comparison study suggests that this background subtraction - wavelet-fitting process - is independent of the detector type and background radiation and is capable of improving the wavelet peak detection probabilities as compared with earlier published results.
