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.

An efficient personal computer-based threedimensional reactor core model TRIDA is developed to simulate the dynamics of the reactor for simulator applications. A fast running matrix factorization technique is used to solve the coupled nodal kinetics equations. Calculations for several off-normal and highly asymmetric transients are performed, and some of the results are compared with those of the Arkansas Nuclear One Unit 2 Final Safety Analysis Report. In addition, the computation time of the matrix factorization technique is compared with those of the Gaussian elimination and Jacobi iterative techniques. Results of comparisons are also given.
