The storage of classified research at all 24 labs run by the US Department of Energy was shut down
this week after officials decided that the security problems recently found at the Los Alamos National
Laboratory in New Mexico might also exist elsewhere.
Several computer disks went missing at Los Alamos earlier this month, forcing Energy Secretary
Spencer Ahraham to stop all work at the lab until the problems are found out. As of 26 July, two missing
disks had still not been found, and 15 employees had been suspended in connection with the
disappearance.
Now all energy labs will stop doing classified research that involves (需要) removable storage
devices-such as computer disks-until all the devices are given explanation for and new procedures are
in place for monitoring their handling by laboratory employees.
"While we have no evidence that the problems being investigated are present elsewhere . we have
a responsibility to take all necessary action to prevent such problems,"Abraham said on 23 July.
The shut-down isn't quite as dramatic (惊人的) as it sounds,expert say. Only two labs will be
seriously affected;Sandia National Laboratory in Albuquerque, New Mexico , and Lawrence
Livemore National Laboratory in Califomia. Together with Los Alamos,these two labs conduct the most
part of the country's nuclear weapon programmes. At Livermore, 876 employees will be suspended
during the storage of some 12,000 items of classified removable material.
At other labs , far fewer people will be affected. " The impact (影响) should be the smallest , "
says Martha Krebs , former director of the energy department's science office.
