The Office of Material Consolidation and Civilian Sites (MCCS) is responsible for three key nuclear nonproliferation initiatives.

Material Protection, Control, and Accounting (MPC&A) Upgrades:

  • Manages cooperative efforts with the Russian Federation to enhance the security of proliferation-attractive nuclear material by supporting material protection, control, and accounting (MPC&A) upgrade projects at civilian nuclear facilities. MCCS has supported MPC&A upgrades at 19 sites throughout Russia, including research institutes and fuel fabrications facilities.


Material Consolidation and Conversion (MCC):

  • Manages the Material Consolidation and Conversion (MCC) project, which is designed to simplify the task of protecting Russia's weapons-usable nuclear materials by reducing the number buildings, and if possible, sites that contain such material. An equally important element of this activity involves the conversion of weapons-usable nuclear material into a form that is significantly less attractive for would-be proliferators (e.g., HEU converted to LEU).


Material Protection, Control, and Accounting (MPC&A) Engagement:

  • Develops MPC&A engagement with countries outside of Russia and the former Soviet Union, including cooperative efforts with China.
