Repairs to a security system at Los Alamos National Laboratory is taking longer than expected.
According to the Albuquerque Journal, lab spokesman Fred deSousa says the planned December completion date of the security system for the lab's plutonium complex has slipped to February.
DeSousa says the work is taking longer than expected because additional problems were found as work was done over the past year.
The work includes repairs to a newly built network of fences, intrusion detection systems and cameras.
A project to upgrade the facility's security was nearly complete when officials discovered in late 2012 that its systems didn't work as intended.
The system is expected to cost a $244 million once the repairs are finished.
