Inspection Report: Follow-up Inspection on Material Control and Accountability at Los Alamos National Laboratory [open pdf - 1MB]
"The Department of Energy's (Department) Los Alamos National Laboratory (Los Alamos) is managed and operated under contract by Los Alamos National Security, LLC, for the National Nuclear Security Administration (NNSA). The Los Alamos Field Office is the Federal entity responsible for administering the contract. This contract requires Los Alamos to follow the contractually specified directives on Material Control and Accountability (MC&A) when maintaining certain nuclear materials in support of the Nation's nuclear weapons stockpile program. Examples of these materials include plutonium and enriched uranium, which are then subdivided into four categories of accountable nuclear material. Categories I and II materials are the most attractive for theft or diversion and include pits or other pure products containing significant quantities of nuclear material. Categories III and IV items are less attractive for theft or diversion because they contain smaller quantities of nuclear material. MC&A is part of the Department's safeguards program designed to establish and track nuclear material inventories, control access to nuclear materials and detect the loss or diversion of nuclear materials. Los Alamos tracks, manages and controls nuclear materials in 64 Material Balance Areas (MBAs). Our September 2007 report on 'Material Control and Accountability at Los Alamos National Laboratory', (DOE/IG-0774) identified weaknesses regarding the control and accountability of nuclear materials. Management committed to implementing the report recommendations and to taking appropriate corrective actions. We initiated this inspection to determine if Los Alamos implemented the planned corrective actions intended to improve the policies and procedures for inventory, transfers, characteristics and locations of nuclear materials related to the MC&A Program."
