SPECIAL NUCLEAR MATERIAL Meaning and
Definition
-
Special nuclear material (SNM) is a term used in the field of nuclear science and technology to refer to a specific category of radioactive substances that are considered to be of significant concern due to their potential for misuse, particularly in the development of nuclear weapons or for causing significant harm in acts of nuclear terrorism.
SNM encompasses a range of materials that are capable of sustaining a nuclear chain reaction, including enriched uranium and plutonium. These materials have unique properties that make them particularly suitable for use in the production of nuclear energy or the creation of nuclear weapons.
Under international agreements and national regulatory frameworks, special nuclear material is subject to strict control and monitoring, with the International Atomic Energy Agency (IAEA) playing a major role in ensuring compliance. These regulations aim to prevent unauthorized access, theft, diversion, or misuse of these materials that could pose a serious threat to international security.
The classification of SNM is based on its enrichment level, which refers to the concentration of fissile isotopes. Highly enriched uranium (HEU) and weapons-grade plutonium are examples of SNM that require the utmost security measures, as they have the potential to cause severe harm if they fall into the wrong hands.
Overall, special nuclear material is a term encompassing radioactive substances that are capable of self-sustaining chain reactions, whose control and safe use are of paramount importance to prevent nuclear proliferation and protect global security.
