Spearheaded by Nuclear Information and Resource Service (NIRS), an environmental coalition letter, signed by Beyond Nuclear and 80 allied organizations, was delivered to every Member of Congress on March 12, 2019 -- one day after the eighth annual commemoration of the Fukushima nuclear catastrophe.
Each congressional office (in both the U.S. House of Representatives, and the U.S. Senate) recieved not only the letter, but also a backgrounder on Yucca Mountain, as well as a backgrounder on Centralized Interim Storage.
