The first of four flanged tritium waste containers awaiting removal from Los Alamos National Laboratory has been vented, the New Mexico Environment Department announced Tuesday afternoon.

The container can now be moved for treatment at LANL and then, eventually, to an off-site disposal area.
No internal pressure was found in the first container, according to the National Nuclear Security Administration, suggesting the inner containers in the flanged tritium waste container hadn’t leaked. Air monitoring did not show an increase of tritium beyond background levels, the federal agency wrote.
No tritium emissions were released, the Environment Department wrote in its Tuesday post on X, formerly Twitter. Both the state agency and the U.S. Environmental Protection Agency are monitoring the process.
The depressurization of the containers is set to continue at 7 a.m. Wednesday, although the NNSA noted the schedule is subject to change due to weather. The four containers will be vented one at a time over an estimated two-week period.
