IAEA

International Atomic Energy Agency based in Vienna (Austria).

National agency for radioactive waste. In France, radioactive waste is managed by the National Agency for Radioactive Waste Management (ANDRA), a public industrial and commercial institution created under the French law of 30 December 1991.

ASN

Nuclear safety authority.

Nuclear fuel is in the form of an assembly made up of an array of 264 fuel rods, bound together by a rigid structure made of tubes and grids. Each fuel rod consists of a water-tight zirconium tube into which uranium oxide pellets are piled, constituting the fuel. The assemblies are loaded side by side into the reactor vessel − 205 assemblies are required for a 1,500MW reactor − to make up the core of the reactor. During operation, these assemblies are crossed by bottom to top with primary water which heats on contact and carries this energy to the steam generators. International legal unit for measuring radioactivity. The Becquerel (Bq) is equal to one disintegration per second. The activity represented by this unit is so low that multiples of it are used: the MBq (megabecquerel or million Becquerels) and the GBq (gigabecquerel or billion Becquerels). Technologies based on biomass mainly consists of burning certain types of waste, particularly from the timber and farming industries, or exploiting wood fuel forests, to produce heat or electricity. Generation technique for combined electricity and heat generation. The advantage of cogeneration is the ability to capture the heat produced by the fuel whereas in traditional electricity generation this heat is lost. This process also allows the same facility to meet the heating (hot water or steam) and electricity needs of both industrial and local authority customers. This system improves the energy efficiency of the generation process and reduces fuel use by an average of 20%. A system allowing for the recording, at a given network connection point, of the volumes of electricity transmitted or distributed (power, frequency, active and reactive energy). Situation in which an interconnection linking the national transmission grids cannot absorb all of the physical flows resulting from international exchanges required by market operators due to a shortage of capacity in the interconnection and/or the national transmission grids involved. French energy regulatory Commission. (CRE). Set up on 30 March 2000, the CRE is an independent administrative authority responsible for contributing to the proper functioning of the electricity and natural gas markets in the interests of final consumers. In this respect, the CRE ensures, in particular, that the conditions for access to electricity and natural gas transmission and distribution networks do not impede the development of competition. The CRE has significant powers: the power to make proposals, advisory powers and decision-making powers. In particular, the CRE proposes regulated tariffs for the sale of electricity. The CRE has decision-making power to set the Tariffs for Using the Public Transmission and Distribution Networks (TURPE). The CRE is also vested with very broad powers that enable it to investigate and obtain any information that it may deem useful for the fulfilment of its remit, as well as authority to settle disputes and to apply penalties. The most recent technology for generating electricity in a natural gas-fired plant. A combined cycle is made up of one or more combustion turbines and a steam turbine allowing for an improved yield. The syngas is routed to the combustion turbine, which generates electricity and very hot exhaust gases (effluents). The heat from the exhaust gases is recovered by a boiler, thus producing steam. Part of the steam is then recovered by the steam turbine to generate electricity. The nuclear fuel cycle encompasses all industrial operations in France and abroad which enable the supply of the fuel to generate energy in a reactor, then to unload and process it. The cycle can be broken down into three stages: upstream: the processing of concentrates from uranium ore, the conversion, enrichment and production of fuel (which takes more ● than two years); the core of the cycle corresponding to the use of fuel in the reactor: receipt, loading, operation and discharging (which takes three ● to five years); downstream: pool storage, reprocessing of spent fuel in reactors of recoverable material, vitrification of highly radioactive waste, ● then temporary storage of the waste before storage.
