Producing a new fuel for West- inghouse and its customer Exelon Nuclear has allowed INL to contribute directly to improving the safety and economics of commercial nuclear power generation. Exelon operates the largest fleet of nuclear plants in the country with 23 reactors located at 14 sites.The fuel pellets fabricated at INL will be inserted into the Byron-2 commercial nuclear reactor in the spring of 2019, completing a very important milestone on the path to eventual licensing of the entirely new fuel system.This success with private nuclear industry is an important milestone for INL and the mission of the Advanced Fuels Campaign. Experimental Fuels Facility The EFF houses a diverse array of fuel fabrication capabilities supporting customers in the U.S. Department of Energy’s (DOE’s) Office of Nuclear
