LIVERMORE, Calif. (AP) — Federal officials say Lawrence Livermore Laboratory is no longer home to some high-security, special nuclear weapons materials.

The National Nuclear Security Administration say the lab will still focus on the safety, security and reliability of the nation's nuclear weapons stockpile, but just with a reduced amount of nuclear material that does not require as much as security as was needed in the past.

The agency says that decision will save about $40 million in taxpayer funds.

NNSA Administrator Thomas D'Agostino says taking the materials out of Livermore is part of a national plan to consolidate special nuclear materials in as few places as possible.

The Oakland Tribune reports (http://bit.ly/OQD1PT) the materials were removed from the lab's Plutonium Facility, which is located in an area known as the "Superblock."
