Workers exposed to airborne uranium, due to pressurised yellowcake containers

Pressurized drums create yellowcake uranium hazard, NRC says By Todd Sperry, CNN Senior Producer July 11, 2012 – Washington (CNN) — After three Canadian employees were exposed to yellowcake uranium last month when a lid blew off a pressurized 55-gallon drum, a uranium mining company has informed U.S. nuclear regulatory officials it has found additional drums possibly susceptible to the same problem, CNN has learned..

.. The NRC and
Canadian nuclear officials are investigating drums shipped from a Willow Creek, Wyoming, mining facility operated by Uranium One to an Ontario processing plant where workers opened them, including the one that ejected the powder. The three employees were overcome by a cloud of yellowcake uranium that had unexpectedly become pressurized.
The worker closest to the drum and two others in the area, who were not wearing respirators, were exposed to airborne uranium, according to the NRC..

… Yellowcake is the byproduct of uranium ore that is mined, crushed and milled until concentrated. It is a key component in manufacturing uranium fuel for nuclear reactors.
NRC officials gave Uranium One until this week to identify whether any other drums had become pressurized during manufacture or shipment…… Other drums shipped to the Canadian facility containing yellowcake were found to be bulging from internal pressure, the NRC said.
