2001: Enters AREVA

The achievement of the French nuclear fleet gives the opportunity to develop a com­plete nuclear industry for design of nuclear plants, exploitation and services, nuclear fuel cycle management, logistics, etc. AREVA, created in 2001, is the industrial heir of 50 years of research, technological innovations and industrial realisations in nuclear equipments and services.

Through its Front end division, Back end division and Reactors and services divi­sion, the AREVA group operates in every area of the nuclear cycle.

In the front end of the cycle, AREVA supplies uranium and offers the conversion and enrichment services needed to fabricate the fuel assemblies that go into the re­actor core. In the Reactors and Services division, the group has the expertise in all the processes and technologies needed for reactor design, construction, maintenance and continuous performance improvement. AREVA focuses principally on the PWR and BWR markets. Research and development programmes are going on about other technologies as HTR and chiefly sodium FBR in relationship with the CEA within international cooperation, such as GEN IV initiative.

The Front End division’s operations include uranium ore exploration, mining and concentration of uranium as U3O8 into uranium hexafluoride (UF6), uranium enrich­ment, and nuclear fuel design and fabrication.

The Reactors and services division is in charge of nuclear power plant design, construction and modernization, nuclear power plant equipment supply, and nuclear services, particularly for scheduled reactor outages.

The Back End division focuses on used fuel treatment and recycling, design and fab­rication of casks for the transportation and storage of nuclear materials, and nuclear materials transportations and logistics.

In summary, the group has now in capacity to:

– sell uranium to its utility customers,

– supply uranium processing services to produce fuel, and design and fabricate fuel assemblies (for PWR and BWR as for experimental research reactors),

– design and build power plants and provide life extension services,

– offer engineering services and equipment to optimize power plant performance,

– recycle its customers’ used fuel to recover reusable materials (uranium and pluto­nium), produce MOX fuel from these recovered materials, treat and package in standardized canisters the ultimate waste for safe disposal.

5.3.2 Conclusion

For nearly 50 years France has developed a comprehensive programme which pro­vides nearly 80% of its electricity without CO2 emissions. This policy has also given the opportunity to create a strong and complete nuclear industry from mining to waste management, including all the aspects of nuclear plants design and services to utilities. The global nuclear renaissance, due to increasing demand and new envi­ronmental issues, gives the opportunity to take advantage of the success story of the French nuclear programme, to diversify the number of customers all over the world and to open new partnerships.

[7] Liquid Core reactor. A closed loop liquid core nuclear reactor where the fissile material is molten uranium cooled by a working gas pumped in through holes in the base of the containment vessel.

• Gas core reactor. A closed loop version of the nuclear lightbulb rocket, where the fissile material is gaseous uranium-hexafluoride contained in a fused silica vessel. A working gas (such as hydrogen) would flow around this vessel and absorb the UV light produced by the reaction. In theory, using UF6 as a working fuel directly (rather than as a stage to one, as is done now) would mean lower processing costs, and very small reactors. In practice, running a reactor at such high power densities would probably produce unmanageable neutron flux.

• Gas core EM reactor. As in the Gas Core reactor, but with photovoltaic arrays converting the UV light directly to electricity.

Seven partners – European Union, China, India, Japan, Russia and USA-have joined together to build the International Thermonuclear Experimental Reactor (ITER) in Caderache in France. ITER will explore the techno-economic feasibility of fusion power. Fusion power is likely come into use only in the second half of the century.

• Periodic Internal Review for Safety assurance. These reviews are conducted by a team of officials independent to executing personnel. The status of implementation of recommendations is reviewed and monitored by Station Director/Project Direc­tor. The Safety Directorate of HQ, also monitors the functioning of these reviews.
