Energy is the natural power stored in matter which can be potential and kinetic energy. This occurs in nature in various forms such as chemical energy, thermal energy, electromagnetic radiation, gravitational energy, electric energy, elastic energy, nuclear energy, and rest energy. The scientific research relating to nuclear energy has revealed that atoms are the foundation of matter. In 1905 Albert Einstein initiated the quantum revolution utilising the Newtonian mass-energy equivalence concept in order to put his famous equation: E =mc2, where energy is (E). This facilitated the nuclear research which focused on manufacturing the first atomic bomb. In 1945 the USA acquired its first two atomic bombs which were dropped on Nagasaki and Hiroshima, killing 200 000 people; mostly civilians. But nuclear energy research has been redirected by scientists in order to industrialise nuclear technology in order to address growing power needs. This encouraged policy makers to consider the risks posed by utilising nuclear energy for civil purposes. The shift towards peaceful nuclear energy applications has been motivated by the many valuable contributions to humankind which nuclear energy offers - for instance in the fields of energy generation, human health, agriculture and industry. The nature of nuclear energy lends itself to becoming an important component of the world energy and global economic system. Nuclear energy is a viable option for many countries including South Africa, because it offers an economic and clean source of electricity; the primary engine for socio-economic development. South Africa operates the only two nuclear power reactors in Africa, (Koeberg 1 and Koeberg 2) generating 1.8 GWe. South Africa’s energy supply infrastructure consists fundamentally of coal-fired power plants which pose serious threats to the environment. Therefore, it is assumed that the planned 9.6 GW of new nuclear capacity by 2030 will meet the requirements of South Africa’s policy regarding the diversification of available energy resources to secure energy supply, support economic growth, and contribute to environmental management. Consequently, the legal system which governs nuclear energy programme is intended to prohibit the proliferation of nuclear weapons, ensure security and maintain the safe operation of nuclear facilities. / Public, Constitutional, and International Law / LL.
