Spent fuel

When did we stop calling it “radioactive waste,” and start calling it “spent fuel”?
Maybe it’s just moms, who have to, um, handle a variation of nuclear waste every day, and who actually fear that radioactive waste will be buried next door for the convenience of politicians who don’t particularly care about the long-term, in this increasingly here today, dont’ care about tomorrow mortgaging of the future political landscape, but are they seriously glossing over the waste problem associated with nuclear power?
I know if we just call torture “enhanced interrogation tactics,” and if we just call civil war “sectatrian violence,” and if we just call religious war “war on terror,” that we can fool most of the people most of the time.
But “spent fuel”?
