The lower-than-expected level of subscriptions from power provider Utah Associated Municipal Power Systems (Uamps) customers led to the cancellation of a project to build a pilot Voygr small modular nuclear plant at the Idaho National Laboratory site, NuScale chief executive officer of John Hopkins has said.

Hopkins told the American Nuclear Society’s Winter Meeting in Washington D.C. that there were “three conditions that the customer [Uamps] told us about a year ago that had to occur for the Carbon Free Power Project [CFPP] to continue to move forward”.
