DOE signs two more OTAs in Reactor Pilot Program
This week, the Department of Energy has finalized two new other transaction agreements (OTAs) with participating companies in its Reactor Pilot Program, which aims to get one or two fast-tracked reactors on line by July 4 of this year. Those companies are Terrestrial Energy and Oklo.

The uptake of tritium by tungsten and its release behavior have been investigated. Specimens annealed at 773 K, 873 K, 973 K, 1,073 K and 1,173 K for 3 hours and loaded with tritium at 773 K for 3 hours accumulated 0.125 ppm, 0.068 ppm, 0.067 ppm, 0.038 ppm and 0.033 ppm, respectively (tritium solubilities were 3.6x 10-9 at.fr.Pa-1/2, 2.0x 10-9 at.fr.Pa-1/2, 1.9x 10-9 at.fr.Pa-1/2, 1.1x 10-9 at.fr.Pa-12/ and 9.7x 10-10 at.fr.Pa-1/2, respectively). The difference is attributed to the existence of trapping sites or oxide films.
