Mexico Declared Free of Weapon-Grade Uranium

Mexico has relinquished the last of its highly enriched uranium in accordance with a nuclear security cooperation deal reached with the United States and Canada, the U.S. National Nuclear Security Administration announced on Tuesday (see GSN, April 13, 2010).

Atomic research reactors in Mexico have been modified to run on low-enriched uranium, which is not refined to nuclear-weapon levels, that would be delivered by the other nations. That allowed for all used and unused HEU material to be withdrawn from the country, the "Rachel Maddow Show" on MSNBC reported.

Mexico pledged at the 2010 Nuclear Security Summit in Washington to rid its territory of all weapon-usable nuclear material (see GSN, April 12, 2011; U.S. National Nuclear Security Administration release, March 20).
