MPC&A

Material Protection, Control and Accounting (MPC&A) refers to the safeguarding of nuclear assets, including nuclear fuel and weapons. In the United States, the <a href="/facts/National_Nuclear_Security_Administration/s0xIr6ka">National Nuclear Security Administration</a> (NNSA), a component of the <a href="/facts/Department_of_Energy/ajkKvrY4">Department of Energy</a>, oversees MPC&A as part of its non-proliferation program. 
The United States-Russia MPC&A program began in 1944, separate and in parallel with the <a href="/facts/United_States_Department_of_Defense/dWAvf7e3">United States Department of Defence</a> (DOD) <a href="/facts/Cooperative_Threat_Reduction/CF0XzMXv">Cooperative Threat Reduction</a> Program, following the passage of the <a href="/facts/Soviet_Nuclear_Threat_Reduction_Act_of_1991/UPn1FQ9X">Soviet Nuclear Threat Reduction Act of 1991</a>. It sought to improve the security of <a href="/facts/Nuclear_weapon/QVdBcMdm">nuclear weapons</a> and nuclear weapons' material through upgrades to material protection, material control and accounting at nuclear sites in <a href="/facts/Russia/jfkCwyxn">Russia</a> and other countries of the former Soviet Union, through cooperation between the <a href="/facts/United_States_Department_of_Energy/PRp6Cz8g">United States Department of Energy</a> and the Russian <a href="/facts/Federal_Agency_on_Atomic_Energy/zoUb9SS8">Federal Agency on Atomic Energy</a> (Rosatom). The program improved the security of thousands of tons of weapons-grade nuclear material in the <a href="/facts/Post-Soviet_states/usrFwWTU">Former Soviet countries</a> (FSU).
