On December 19, 2019 the Company was awarded a voucher from the U.S. Department of Energy’s (DOE) Gateway for Accelerated Innovation in Nuclear (GAIN) program to support development of Lightbridge Fuel™ in collaboration with Idaho National Laboratory (INL). The scope of the project includes experiment design for irradiation of Lightbridge metallic fuel material samples in the Advanced Test Reactor (ATR) at INL. The project is anticipated to commence in the second quarter of 2020. The total project value is approximately $846,000, with three-quarters of this amount funded by DOE for the scope performed by INL. No work was done by INL that caused the DOE to incur payment obligations related to the voucher for the three months ended March 31, 2020 and the year ended December 31, 2019.
