"Reprocessing belongs to a bygone era—not today’s nuclear energy resurgence. It has failed on cost, failed on security, and failed to deliver real benefits. The future belongs those who pick proven technologies that can be deployed now and rapidly scaled," writes Ross Matzkin-Bridger.

To Lead in Nuclear Energy, the U.S. and Korea Must Avoid the Reprocessing Trap
One of the most consequential decisions countries will face is whether to take a costly detour into nuclear fuel reprocessing, a technology that has failed every promise it has made.

Fun Fact: the United States tests nuclear delivery vehicles like missiles all the time. What no one has done this century, other than North Korea, is detonate a nuclear weapon.
The US will launch an ICBM across the Pacific — and no, it has nothing to do with Trump's new nuclear testing plans
The routine exercise comes amid confusing remarks from US President Donald Trump and other officials about America restarting nuclear tests.

The same logic applies today: It is unnecessary, unwise, and unwelcome.
