CARLSBAD, N.M. (AP) - Workers at the federal government's nuclear waste repository in southern New Mexico are installing a temporary ventilation system that will increase airflow in the underground facility.
The system will include two above-ground filter units and fans that will be connected to ductwork that feeds the underground portions of the Waste Isolation Pilot Plant.
The plant has been closed for more than a year following a radiation release that stemmed from a chemical reaction among waste improperly packed inside a drum at Los Alamos National Laboratory.
Since the February 2014 mishap, all air exiting the underground passes through filters. Ventilation of the underground is reduced based on the filter capacity.
