Troubled nuke dump makes progress on ventilation system

CARLSBAD, N.M. (AP) - Managers at the nation's only underground nuclear waste repository say they're making progress on the facility's new interim ventilation system.
           
They say subcontractors completed work this week to tie in the new system to existing ductwork. The new system is expected to increase airflow in the underground by about 54,000 cubic feet per minute.
           
Adequate ventilation has been a concern as the Waste Isolation Pilot Plant prepares to resume some operations at the end of 2016.
           
The plant has been shuttered since February 2014, when an improperly packed drum of waste from Los Alamos National Laboratory popped its lid and released radiation.
           
Officials say workers began testing the ventilation system for leaks Wednesday. Other electrical and mechanical work is expected to be done by the end of the week.
