The 2 billion year old natural fission reactors in gabon western africa scientific american. Originally published in the october 2005 edition of scientific american evelyn mervine nature s nuclear reactors. Meshik the workings of an ancient nuclear reactor scientific american 26 january 2009.
Wilson p d the nuclear fuel cycle oup 1996 alex p. References notes general references. Its purpose is to provide the iaea its member states and public users with current consistent and readily accessible information on existing closed and planned nuclear fuel cycle facilities throughout the world.
The nuclear fuel cycle information system nfcis is an international directory of civilian nuclear fuel cycle facilities. Nuclear fission is the dominant nuclear energy generation method and both open fuel cycle and closed fuel cycle can be utilized depending on whether the spent fuel is re cycled or not. A nuclear fuel cycle is the path that we put heavy atoms through in order to extract energy from them starting at the day we find them and ending when their wastes have decayed to stability and are no longer dangerous.
Back end help from maru morell gonzalez. By nick touran june 2009. What is a nuclear fuel cycle.
This self study module is designed to assist you in. The purpose of this module is to provide a basic overview of the nuclear fuel cycle. This is the first of nine modules available in this self study course.
Welcome to module 1 0 of the fuel cycle processes directed self study course. Overview of the nuclear fuel cycle. As illustrated below the nuclear fuel cycle typically includes the following stages.
Mixed oxide is another type of nuclear fuel.
Nuclear fuel cycle diagram. The nuclear fuel cycle also called nuclear fuel chain is the progression of nuclear fuel through a series of differing stages. It consists of steps in the front end which are the preparation of the fuel steps in the service period in which the fuel is used during reactor operation and steps in the back end which are necessary to safely manage contain and either reprocess or dispose of. The nuclear fuel cycle. Industrial processes which involve the production of electricity from uranium in nuclear power reactors.
Electricity is created by using the heat generated in a nuclear reactor to produce steam and drive a turbine connected to a generator. Fuel removed from a reactor after it has reached the end of its useful life can be reprocessed to produce new fuel. The nuclear fuel cycle is a process chain consisting of a series of differing stages. The nuclear fuel cycle starts with the mining of uranium and ends with the disposal of nuclear waste.
With the reprocessing of used fuel as an option for nuclear energy the stages form a true cycle. The nuclear fuel cycle consists of front end steps that prepare uranium for use in nuclear reactors and back end steps to safely manage prepare and dispose of used or spent but still highly radioactive spent nuclear fuel. Uranium is the most widely used fuel by nuclear power plants for nuclear fission. Nuclear power plants use a certain type of uranium u 235 as fuel because its.
The nuclear fuel cycle represents the progression of nuclear fuel from creation to disposal. In the united states uranium is processed in different chemical and physical forms to create nuclear fuel.
