The world’s stock of nuclear fissile material – highly enriched uranium (HEU) and
plutonium – amount to nearly 1900 metric tons, enough to build more than 20000
new weapons like the one used in Hiroshima and more than 80000 like the one that
destroyed Nagasaki. Most of the fissile material is in military stocks (83 percent); the
rest is in civilian stocks (17 percent). Both types of stocks are vulnerable to diversion
and can be used directly in a simple nuclear device. Twenty-four countries hold fissile
nuclear material. Almost every country in the world has radioactive material. Some
types of high-risk radioactive material can be used in a radioactive dispersal device
("dirty bomb"). Should a nuclear incident involving nuclear or high-risk radioactive
material take place in any part of the world, the repercussions will be of global nature.
Most notable, such incident will disrupt supply chains, disturb interconnected financial
markets, and negatively impact, if not collapse, individual industries (sea container
shipping being one example).

Nuclear security, as a term, can mean many different things depending on the
context. The international community has a number of guidance documents which
assist countries with nuclear and radiological material security plan development. The
International Atomic Energy Agency, as well as other organizations, provide general
materials available to assist in the evaluation of threats posed to the locations housing
the materials as well as recommendations as to managing a security incident. Be-
cause much of the specific security plan is sensitive, technical staff from Oak Ridge
National Laboratory have developed innovative training methods to share the inter-
national best practices in a way which can be adapted to the specific infrastructure,
