Bottois, P.

2009-01-01

Siemens announced in January 26, 2009 its decision to leave Areva NP, i.e. the Areva/Siemens common daughter company for reactors. This news re-launches the questions about the long-term financing strategy of the Areva group, of its capitalistic partnerships and of its position in the world nuclear market. Siemens on its side wishes to preserve its position in this market and a possible cooperation with the Russian AtomEnergoProm is under discussion. Areva, the world leader of nuclear industry, integrates a mining activity as well and is the world number 3 of uranium exploitation (15% of the world offer). It wishes to double its production by 2012 thanks to big investments in Niger, Namibia and Canada. Areva is developing its enrichment capacities as well thanks to the future Georges-Besse II ultracentrifugation facility which is under construction at Tricastin (Drome, France) and which should be put into service in 2009. And finally, a second EPR (European pressurized reactor), the new generation of Areva reactors, is to be built at Penly (Haute Normandie, France) between 2012 and 2017 and will generate 1400 employments in the region.

AREVA decommissioning strategy and programme

International Nuclear Information System (INIS)

Gay, A.

2008-01-01

As with any industrial installation, a nuclear facility has an operating life that requires accounting for its shutdown. In compliance with its sustainable development commitments, AREVA accounts this via its own decommissioning resources to value and make sites fit for further use. These capabilities guarantee the reversibility of the nuclear industry. Thus, the nuclear site value development constitutes an important activity for AREVA, which contributes to the acceptance of nuclear in line with the AREVA continuous policy of sustainable development which is to be fully responsible from the creation, during the operation, to the dismantling of its facilities in all respects with safety, local acceptance and environment. AREVA has already performed a large variety of operation during the life-time of its installations such as heavy maintenance, equipment replacement, upgrading operation. Nowadays, a completely different dimension is emerging with industrial decommissioning operations of nuclear fuel cycle installations: enrichment gaseous diffusion plant, fuel assembly plants, recycling and reprocessing facilities. These activities constitute a major know-how for AREVA. For this reason, the group decided, beginning of 2008, to gather 4 projects in one business unit called Nuclear Site Value Development - a reprocessing plant UP2 400 on AREVA La Hague site, a reprocessing plant UP1 on AREVA Marcoule site, a MOX fuel plant on Cadarache and 2 sites (SICN Veurey and Annecy) that handled GCR fuel fabrication). The main objectives are to enhance the feed back, to contribute to performance improvements, to value professionals and to put innovation forward. The following article will describe in a first part the main decommissioning programmes managed by AREVA NC Nuclear Site Value Development Business Unit. The second part will deal with strategic approaches. A more efficient organization with integration of the supply chain and innovation will be part of the main drivers

Areva: 2014 annual results

Repaire, Philippine du

2015-01-01

The scale of the net loss for 2014 illustrates the twofold challenge confronting AREVA: continuing stagnation of the nuclear operations, lack of competitiveness and difficulties in managing the risks inherent in large projects. The group understands how serious this situation is. A comprehensive strategic review of operations was undertaken beginning in November 2014 and is being carried out without compromise. As a result, AREVA is now able to announce a solid transformation plan that sets a challenging but economically realistic course for its teams. First, AREVA will refocus on its core business: mastery of key nuclear processes essential to operators around the globe. This strategic redeployment will lead to the revision of certain goals, whether in the management of new reactor projects or in renewable energies. AREVA's objective is to achieve excellence as a high value-added supplier of products and services. Secondly, AREVA, whose resources had been marshaled to support a spurt of growth in nuclear power, must now adapt to new market realities and become competitive once again. The group's most urgent task is recovery and securing its future by immediately launching a far-reaching competitiveness plan founded on organizational simplification, quality of operations, and a completely revamped approach to managing risk in large projects. Last but not least, AREVA must ensure sustainable financing for its activities. A financing plan will be clarified before publication of the half-year financial statements. This document presents the key financial data of the group, its strategic road-map and its operating and financing plans

This article comments the difficulties and problems faced by Areva for its activity of nuclear reactor construction, and which leaded to the transfer of this activity from Areva to EDF while Areva will keep its uranium providing and fuel enrichment activities. These difficulties and problems concern the Flamanville EPR (the construction is 5 years late, vessel defects have just been identified, cost overruns), the Finnish EPR (7 years late, a 5 billions cost overrun), the Jules Horowitz research reactor (5 years late, cost overrun), and strategic choices (notably with respect to the post-Fukushima context). The article also outlines that other activities (mining, enrichment, reactor maintenance) are still doing well, and then briefly discusses the future of Areva NP

While Areva keeps on loosing money (billions of euros for 2014), the saving of this company is at stake. Staff is already planned to be reduced in La Hague, and other staff reductions might occur after the failure of a previous strategic plan. Various activities could be sold (dismantling, mining). The article outlines the difficult relationships between Areva and EDF and the problems also faced by EDF. Some actors think that Areva should remain independent from EDF in order to be free to compete on international bidding. The rapprochement between these two companies is said to be necessary for the Ministry but seems very difficult to achieve

Over the years, AREVA globally has maintained a strong expertise in LWR water chemistry and has been focused on minimizing short-term and long-term detrimental effects of chemistry for startup, operation and shutdown chemistry for all key plant components (material integrity and reliability, promote optimal thermal performances, etc.) and fuel. Also AREVA is focused on minimizing contamination and equipment/plant dose rates. Current Industry Guidelines (EPRI, VGB, etc.) provide utilities with selected chemistry guidance for the current operating fleet. With the next generation of PWR plants (e.g. AREVA's EPR TM reactor), materials of construction and design have been optimized based on industry lessons learned over the last 50+ years. To support the next generation design, AREVA water chemistry experts, have subsequently developed a Chemistry Guidebook with chemistry guidelines based on an analysis of the current international practices, plant operating experience, R and D data and calculation codes now available and/or developed by AREVA. The AREVA LWR chemistry Guidebook can be used to help resolve utility and safety authority questions and addresses regulation requirement questions/issues for next generation plants. The Chemistry Guidebook provides water chemistry guidelines for primary coolant, secondary side circuit and auxiliary systems during startup, normal operation and shutdown conditions. It also includes conditioning and impurity limits, along with monitoring locations and frequency requirements. The Chemistry Guidebook Guidelines will be used as a design reference for AREVA's next generation plants (e.g. EPR TM reactor). (authors)

In 2011 AREVA launched 2 worldwide programs to meet the demands of its customers: 'AREVA Safety Alliance' that proposes a set of measures for post-Fukushima safety upgrading and 'AREVA Forward Alliance' that is dedicated to lifetime extension projects. Concerning 'AREVA Safety Alliance' about 150 projects have been carried out for 53 customers in 19 countries, as for 'AREVA Forward Alliance' 60% of the lifetime extension projects in the US have been performed by AREVA. In the framework of lifetime extension projects, upgrading measures and services are proposed such as the installation of hydrogen recombiner units, of filtered ventilation systems for severe accidents, or the upgrading of the reactor control system through the implementation of the digital Teleperm XS technology, or recommendations about the methodology to follow for the repair or replacement of important components. The replacement of steam generators and of the pressurizer and with other upgrading works led to a gain of 18.5% on the output power of the Ringhals-4 unit. (A.C.)

AREVA being an operator of nuclear facilities has to organize crisis exercises regularly. About 100 crisis exercises are performed each year in AREVA installations. These exercises allow the training of the staff, the assessing of material and humane means and the checking of the quality of the interfaces between all the participants (other AREVA teams or Nuclear Safety Authority or...). The management of nuclear crisis is based on anticipation and relies on 3 pillars: a referential gathering all the useful documents (emergency plans, procedures,...), the training and practice of AREVA staff in specific domains to cope with emergency situations, and various crisis exercises to keep fit all the teams. The basis emergency exercise lasts 2 hours and is organized into modules. First module: detecting abnormal conditions, alerting, rescuing and limiting the consequences; second module: launching the emergency plan; third module: understanding the situation and limiting the consequences; fourth module: communicating with other actors that intervene in a nuclear crisis (nuclear safety authority, state or local officials, the media...); and fifth module: anticipating the end of the emergency phase to prepare post-accidental management.

In 2002 the consolidated turnover of Areva reached 8265 million euros, it means a decrease by 7,2% in comparison with 2001. This decrease is due to the sharp drop of the turnover of the connector sector (-20,7%) while the nuclear sector was stable. The bad figure of connectors engineering is linked to a new collapse of the telecommunication market. In 2002 the operational result of Areva reached 180 million euros, that is to say an increase by 48%, which is a consequence of progress made in the nuclear sector. (A.C.)

Dans ce travail est presente un systeme de generation d'energie d'un parc eolien offshore et un systeme de transport utilisant les stations VSC-HVDC connectees au reseau principal AC onshore. Trois configurations ont ete etudiees, modelisees et validees par simulation. Dans chacune des configurations, des contributions ameliorant les cotes techniques et economiques sont decrites ci-dessous : La premiere contribution concerne un nouvel algorithme MPPT (Maximum Power Point Tracking) utilise pour l'extraction de la puissance maximale disponible dans les eoliennes des parcs offshores. Cette technique d'extraction du MPPT ameliore le rendement energetique de la chaine de conversion des energies renouvelables notamment l'energie eolienne a petite et a grande echelles (parc eolien offshore) qui constitue un probleme pour les constructeurs qui se trouvent confrontes a developper des dispositifs MPPT simples, moins couteux, robustes, fiables et capable d'obtenir un rendement energetique maximal. La deuxieme contribution concerne la reduction de la taille, du cout et de l'impact des defauts electriques (AC et DC) dans le systeme construit pour transporter l'energie d'un parc eolien offshore (OWF) vers le reseau principal AC onshore via deux stations 3L-NPC VSCHVDC. La solution developpee utilise des observateurs non-lineaires bases sur le filtre de Kalman etendu (EKF). Ce filtre permet d'estimer la vitesse de rotation et la position du rotor de chacune des generatrices du parc eolien offshore et de la tension du bus DC de l'onduleur DC-AC offshore et des deux stations 3L-NPC-VSC-HVDC (offshore et onshore). De plus, ce developpement du filtre de Kalman etendu a permis de reduire l'impact des defauts AC et DC.

China has a great need for secure, safe, and economic energy supplies that combat the greenhouse effect and global warming. Since January 2002, China, the most heavily populated country with more than 1.3 billion inhabitants in a territory of 9.5 million km 2 (17 times larger than France), has a nuclear capacity of 9 GWe with 11 nuclear plants on line. Forecasts of electricity consumption report a need for 900 to 1,000 GWe per year through 2020, and at this time the country's objective is to increase nuclear generated electricity from 1% to 4% of its total output. This means a need for additional 30 GWe, which is the equivalent of twenty 1,500 MWe reactors. In addition to nuclear power, China is pushing renewable energy. With the passage of the 2005 Renewable Energy Law, China's government imposed a national renewable energy requirement that is expected to boost the use of renewable energy capacity from 10 to 12 percent by 2020, up from 3% in 2003. This law requires power operators to buy electricity from alternative energy providers and gives economic incentives to these providers. Consequently, China is expanding its interests in renewable energy sources including wind and bio-energies, among others. It is in this context that AREVA, a world expert in energy, creates and offers solutions to generate, transmit, and distribute electricity for China. Based on its long experience and global presence, AREVA has become the worldwide leader for nuclear energy in the areas of construction, equipment, and services for nuclear power plants, and for the whole nuclear fuel cycle. AREVA is also a world leader in electrical power-grid equipment and systems. This document presents: China's need for energy; the Sources of China's energy mix; the challenges of China's nuclear program; AREVA's action in supporting China's ambitious nuclear program; the strong opportunities in renewable energy; and the high potential market for AREVA's T and D Division

AREVA in Mongolia - Press kit

Mongolia is going through a crucial period in its history and setting up a strategic policy for uranium. The choices that are being made will affect the country and its future. Mongolia, since the mid-2000's, has benefited from significant mining development that has nourished the strong growth of the country. The giant Oyu Tolgoi (gold and copper) and Tavan Tolgoi (coal) deposits are the symbols of this mining potential. Uranium in particular has a major strategic role. The exploration programmes have revealed the presence of exploitable resources. On 26 February 2013, the Professional Council of Mineral Resources with the Ministry of Mines officially classified the Zoovch Ovoo deposit's with more than 50 000 tons of uranium. Following classification of the deposit of Dulaan Uul in 2011, the Zoovch Ovoo classification makes Mongolia officially one of the top 10 countries with the largest uranium resources. Mongolia has set about making the uranium industry a centrepiece of its strategy and its policy of independence. This new approach is founded in the Nuclear Energy Act adopted in the summer of 2009. The Mongolian State wants to create a uranium industry that makes Mongolia a nuclear fuel supplier for the Asian market. The choice of partners with whom the country associates to mine the uranium deposits is therefore important. Agreements have notably entered into with France, through AREVA which is a public company, as well as with Russia, China, Japan and India. AREVA has been present in Mongolia since 1997. AREVA is today represented in Mongolia by AREVA Mongol, its 100% subsidiary. AREVA Mongol carries out its exploration activities through Cogegobi and will manage its mining licences through AREVA Mines LLC. AREVA holds several exploration licences in Mongolia covering over 9,000 km 2 in the provinces of Dornogobi and Sukbaatar, where COGEGOBI is conducting its drilling programmes. This first phase has led to the first project-development steps

Marincic, A.

2009-01-01

A reasonable assumption for the estimated new build market for the next 25 years is over 340 GWe net. The number of prospect countries is growing almost each day. To address this new build market, AREVA is developing a comprehensive portfolio of reactors intended to meet a wide range of power requirements and of technology choices. The EPR reactor is the flagship of the fleet. Intended for large power requirements, the four first EPRs are being built in Finland, France and China. Other countries and customers are in view, citing just two examples: the Usa where the U.S. EPR has been selected as the technology of choice by several U.S utilities; and the United Kingdom where the Generic Design Acceptance process of the EPR design submitted by AREVA and EDF is well under way, and where there is a strong will to have a plant on line in 2017. For medium power ranges, the AREVA portfolio includes a boiling water reactor and a pressurized water reactor which both offer all of the advantages of an advanced plant design, with excellent safety performance and competitive power generation cost: -) KERENA (1250+ MWe), developed in collaboration with several European utilities, and in particular with Eon; -) ATMEA 1 (1100+ MWe), a 3-loop evolutionary PWR which is being developed by AREVA and Mitsubishi. AREVA is also preparing the future and is deeply involved into Gen IV concepts. It has developed the ANTARES modular HTR reactor (pre-conceptual design completed) and is building upon its vast Sodium Fast Reactor experience to take part into the development of the next prototype.

Areva group, the world leader of the nuclear industry, is looking for 5 billion euros to finance its investments. However, the French government which owns 90% of the group, mainly through the CEA, is not willing to supply this financial help. Therefore, about 40% of Areva group's turnover could change hands soon. In fact, the French government has asked Areva to consider the selling of its daughter company T and D (Transmission and Distribution) which is one of the major poles of the group's activity. Thanks to T and D, Areva can propose a complete range of products, services and systems from the low- to the extra-high voltage, and can be present on other energy markets, from the conventional to the renewable power generation. Already weakened by the departure of Siemens, Areva, without T and D would lose its full power in front of competitors like GE-Hitachi, Toshiba-Westinghouse or Rosatom-Siemens. (J.S.)

International Nuclear Information System (INIS)

2015-01-01

This document is Areva Namibia's stakeholder report for 2013-2014. The focus of this edition is on Areva Namibia's involvement in the community. The Trekkopje project went into a 'Care and Maintenance' phase from 1 July 2013. The mine is merely in a holding phase with every intention to start up as soon as the economic conditions become more favourable. Since then, the Care and Maintenance team has been protecting the assets and kept the mine's infrastructure in working condition so that it can be commissioned without delay. However, Areva is still present and actively engaged with its stakeholders at the local, regional and national level. Neighbouring communities are benefiting from social projects in Arandis, Swakopmund and the wider Erongo region. Areva is actively supporting economic development through the Erongo Development Foundation's SME micro-finance scheme and education projects. At the regional level, Areva's desalination plant has enabled NamWater to meet the water demand of Swakop Uranium's new Husab mine. Furthermore, water supply to the Roessing and Langer Heinrich mines could be sustained when pumping water from the Omaruru Delta (Omdel) aquifer at Henties Bay had to be reduced due to over-exploitation. Areva has recently started negotiations with the Government of the Republic of Namibia about the sale of the Erongo desalination plant. Areva is also involved in the mining industry as members of the Namibian Chamber of Mines and the Namibian Uranium Association (NUA). The NUA plays an important role in setting standards to ensure that local mining practices comply with global standards on sustainable development, environmental protection and radiological safety. One of Areva's major achievements in 2014 was the completion of the second phase of metallurgical test work with very promising results. The Care and Maintenance phase is the opportunity to thoroughly research the alkaline heap leach process and

The author comments the answers to a call for tender made by the French government and concerning five offshore wind farm sites (Le Treport, Fecamp, Courseulles sur Mer, Saint-Brieuc and Saint-Nazaire). As they are present within the three consortiums, Areva and Alstom should provide the wind turbines. This would result in the construction by Alstom of two blade and mast factories and two turbine and pad factories. For both companies, this market of 500 to 600 turbines is an opportunity. Many jobs are at stake. They push themselves forward for their experience or their innovation capacity. But their wind turbines will be based on foreign (Spanish or German) technology

Areva's 44-billion euro backlog at the end of 2010 gives the group excellent visibility, enabling it to confirm its outlook for 2012: 12 billion euros in revenue, double-digit operating margin and significantly positive free operating cash flow. Revenue rose by 575 million euros in 2010, or 6.7%, in comparison to 2009 and operating income excluding particular items improved by 201 million euros, nearly 2 points of revenue. In the past two years, Areva has raised 7.1 billion euros and secured its liquidity to ensure its development. In 2011, Areva is going to simplify the group's capital structure by listing ordinary shares of AREVA. At that time, the group may launch the employee share-holding plan, something it has ardently sought for several years as a way for its employees to share in AREVA's growth. The consolidated backlog stood at 44.204 billion euros at December 31, 2010, up 2.0% compared with that at December 31, 2009. The group's consolidated revenue came to 9.104 billion euros in 2010, up 6.7% on a reported basis and 5.1% like-for-like compared with 2009. Excluding particular items, operating income rose by 1.9 point, going from 3.9% in 2009 to 5.8% in 2010, giving operating income of 532 million euros (331 million euros in 2009). Net income attributable to equity owners of the parent came to 883 million euros in 2010, an increase of 331 million euros compared with 2009. Operating cash flow before capex was 923 million euros, an increase of 548 million euros compared with 2009, when it was 375 million euros, due to the visible improvement in EBITDA and working capital requirement. The change in gross capex (excluding acquisitions) from 1.780 billion euros in 2009 to 1.966 billion euros in 2010 is due to the ramp-up of construction programs, particularly in Enrichment. In 2010, almost 60% of the group's capital spending was on sites in France. The acquisitions made in Renewable Energies in 2010 in the amount of 210 million euros

The results achieved in the nuclear energy field illustrate the exemplary nature of the cooperation between France and China. Over 20 years, China has developed the nuclear technology for generating electricity, using the expertise and knowledge of the AREVA Group. AREVA has been present in China since 1986 and now employs 3,500 staff there. The group supplied the nuclear islands for 4 reactors at Daya Bay and Ling Ao as well as technology and equipment for 4 more reactors at the Qinshan II and Tianwan plants. AREVA has developed an ambitious program for transferring technology to the Chinese industry and developing local skills. The group's objective is to remain China's partner of choice in terms of its nuclear program. During an official visit to France in June 2004, China's Vice Premier Zeng Peiyan said he was in favor of 'overall and long-lasting cooperation between China and France in the field of nuclear energy'. AREVA took the opportunity to sign two letters of intent for cooperation over technology from its next generation of nuclear reactors. Electricity consumption forecasts report a need for 900 GW through 2020 and the country's objective is to increase nuclear-generated electricity from 1% to 4% of its total output (36 GW: the equivalent of around twenty 1,500 MWe reactors). An official decision to build 4 new reactors was announced in July 2004 and a further decision concerning another 4 reactors is expected in the near future. Various construction sites are being considered, mainly along the country's eastern coast. An official decision to build four duplicate reactors was announced n July 2004. In addition to these four duplicate reactors to be built on existing sites, China has decided to build four 3. generation reactors at Yangjiang and Sanmen. An international call for tender was launched on September 28, 2004. AREVA will reply to the tender by offering its EPR model. AREVA also aims to expand its Chinese operations into exploring and extracting

Areva group, the world leader of the nuclear industry, is looking for 5 billion euros to finance its investments. However, the French government which owns 90% of the group, mainly through the CEA, is not willing to supply this financial help. Therefore, about 40% of Areva group's turnover could change hands soon. In fact, the French government has asked Areva to consider the selling of its daughter company T and D (Transmission and Distribution) which is one of the major poles of the group's activity. Thanks to T and D, Areva can propose a complete range of products, services and systems from the low- to the extra-high voltage, and can be present on other energy markets, from the conventional to the renewable power generation. Already weakened by the departure of Siemens, Areva, without T and D would lose its full power in front of competitors like GE-Hitachi, Toshiba-Westinghouse or Rosatom-Siemens. (J.S.)

Sustainable development of Areva Mongol and Cogegobi. Report 2014

International Nuclear Information System (INIS)

2015-10-01

This document is Areva Mongol's stakeholder report for 2014. Areva started its exploration operations in Mongolia in 1997 via its subsidiary COGEGOBI and long before the so-called 'mining boom'. Throughout the last decade, Areva made significant investments to bring its geological exploration works to success, which led to the successive discoveries of the Dulaan Uul and Zuuvch Ovoo deposits. These breakthroughs, by almost doubling the account of Mongolia's official uranium resources, have now positioned the country as a possible future major uranium producer. 2014 has been a year of hard work and great achievements for the company. Areva successfully completed the technical and economic feasibility studies of both deposits. The company restored its relationships with local authorities, herders and local citizens, to a point where it now reach some level of mutual understanding. Since the very beginning of its presence in Mongolia, Areva has brought support to local institutions and citizens. The livestock health project that Areva Mongol is funding, has a double objective to clarify the causes of livestock diseases observed in Ulaanbadrakh sum which cause doubts among the local community, as well as to bring direct support to herders in Areva's project area. Areva is waiting the approval of the Feasibility Study of Dulaan Uul and Zuuvch Ovoo uranium deposits mining by the Professional Council of the Mineral Resources Authority and the granting of mining licenses on these areas to Areva Mines LLC. The objective will be to launch the operations of Areva Mines LLC, the joint-venture with the Mongolian state owned partner Mon-Atom. This will be a first step towards Mongolia becoming a uranium exporter being involved itself in the uranium mining for the first time in its history.

This article discusses the future of Areva as a part of its activities (nuclear reactor building and maintenance) is now managed by EDF. The author notices that Areva's present situation looks like the Cogema's one before its merge with Framatome and some CEA activities to give birth to Areva. The main problem is the debt for a group which possesses important assets (hyper-profitable uranium mines, advanced technology plants for nuclear fuel processing) and opportunities (the possibility to become a leader in the dismantling activity, to take advantage of the increasing uranium demand), but is unable to self-finance, suffers from its heavy organisation which needs to be reviewed and even separated into two companies, and is also threatened by the cost of new reactors and by being too small to launch new projects in front of the giants of the mining sector

After the phase of strategic choices and definition of competitiveness objectives, AREVA entered the phase of operational execution of its transformation plan. Despite a still depressed market environment, the Group is beginning to measure the first results of its efforts to restore its financial situation. Thanks to the actions undertaken, the cash consumption pace was sharply slowed down compared to what had been anticipated. In summary: Rise in revenue to euro 2.947 bn: +10.3% vs. September 2014 (+8.7% like for like); - Backlog of euro 31.595 bn; - Discontinued operations, including AREVA NP: - Revenue of euro 2.732 bn: -7.5% vs. September 2014, - Backlog of euro 12.872 bn. Progress on the transformation plan in the third quarter: - Social dialogue: signature of the group agreement on the employment plan and submittal of documents describing the group's reorganization plans to employee representation bodies as part of a job-saving plan; - Continued deployment of actions for operational performance; - Strategic partnership with EDF: finalization of due diligence for the sale of AREVA NP; - Decisions on capital increase taken before the end of 2015

AREVA expanded its backlog and increased its revenues compared with 2008, on strong installed base business and dynamic major projects, fostering growth in operating income of 240 million euros. As announced previously, Areva is implementing a financing plan suited to its objectives of profitable growth. The plan was implemented successfully in 2009, including the conclusion of an agreement, under very satisfactory terms, to sell its Transmission and Distribution business for 4 billion euros, asset sales for more than 1.5 billion euros, and successful bond issues of 3 billion euros. The plan will continue in 2010 with a capital increase, the completion of asset disposals and cost reduction and continued operational performance improvement programs. Areva bolstered its Renewable Energies business segment by supplementing its offshore wind power and biomass businesses with the acquisition of Ausra, a California-based leader in concentrated solar power technology. Despite the sale of T and D, Areva is maintaining its financial performance outlook for 2012: 12% average annual revenue growth to 12 billion euros in 2012, double digit operating margin and substantially positive free operating cash flow. Annual results 2009: - For the group as a whole, including Transmission and Distribution: Backlog: euros 49.4 bn (+2.5%), Revenues: euros 14 bn (+6.4%), Operating income: euros 501 m (+20.1%); - Nuclear and Renewable Energies perimeter: Backlog: euros 43.3 bn (+1.8%), Strong revenue growth: +5.4% to euros 8.5 bn, Operating income before provision for the Finnish project in the first half of 2009: euros 647 m, Operating income: euros 97 m, for a euros 240 m increase from 2008; - Net income attributable to equity holders of the parent: euros 552 m, i.e. euros 15.59 per share; - Net debt: euros 6,193 m; - Pro-forma net debt, including net cash to be received from the sale of T and D in 2010: euros 3,022 m; - Dividend of euros 7.06 per share to be proposed during the Annual

In 2011, AREVA's consolidated revenue came to 8.872 billion euros, down slightly (-2.6%) compared with 2010 (-1.2% like for like). The decrease in revenue in nuclear operations was partially offset by significant growth in the renewable energies business. Foreign exchange and changes in the scope of consolidation had respectively a negative impact of 113 million euros and 16 million euros over the period. Revenue totaled 2.922 billion euros in the fourth quarter of 2011, stable compared with the fourth quarter of 2010 (-0.5% on a reported basis and -0.5% like for like). Foreign exchange had a negligible impact during the period. Led by nuclear operations, the group's backlog was 45.6 billion euros at December 31, 2011, up 3.1% year on year and 6.7% in relation to September 30, 2011. Order cancellations since Fukushima were limited to 464 million euros as of December 31, 2011. In accordance with the requirements of IFRS 8, AREVA's business segment information is presented for each operating Business Group (BG), which is the level of information examined by the group's governance bodies. Subsequent to the establishment of a subsidiary combining all of the group's mining operations, data for the Mining Business Group are now reported separately from those of the Front End Business Group. Data used for comparisons with 2010 were restated to reflect this new organization. The business segment information therefore corresponds to AREVA's five operating Business Groups: Mining, Front End, Reactors and Services, Back End and Renewable Energies

For its future uranium enrichment plant of its Tricastin site (Drome, France), the world nuclear leader Areva has abandoned the gaseous diffusion technique (of French origin) for the centrifugation technique, more economical and modular. This future plant, named 'Georges Besse 2' will require 3 billions of euros of investment and will supply a world market also estimated to 3 billions of euros and shared between Areva, Urenco (UK), Usec (US), Minatom (Russia), JNC (Japan) and CNNC (China). The first batches of enriched uranium will be produced using a thousand of centrifuges by 2007. (J.S.)

This paper introduces AREVA's High Temperature Reactor (HTR) steam cycle concept for near-term industrial deployment. Today, nuclear power primarily impacts only electricity generation. The process heat and transportation fuel sectors are completely dependent on fossil fuels. In order to impact this energy sector as rapidly as possible, AREVA has focused its HTR development effort on the steam cycle HTR concept. This reduces near-term development risk and minimizes the delay before a useful contribution to this sector of the energy economy can be realized. It also provides a stepping stone to longer term very high temperature concepts which might serve additional markets. A general description of the current AREVA steam cycle HTR concept is provided. This concept provides a flexible system capable of serving a variety of process heat and cogeneration markets in the near-term.

Teule, Rianne; Thomas, Steve

2009-06-01

As EDF and Areva have been developing for several years a strategy exclusively based on a nuclear revival in the world, this document proposes a synthesis of a study in which the author describes and analyses this strategy, as well as the actual trade perspectives of the sector, and outlines the many uncertainties regarding development projects. It addresses the financial and political context for EDF (a record indebtedness) and Areva (an inability to face investments) and outlines the supporting role of the Coface (the only way for the French government to support EDF and Areva). It highlights and discusses the failures of both ERP projects, in Flamanville (cost overruns and consequences) and in Finland. It addresses the actual status of markets, notices that France's strategy (lifetime extension for the existing reactors) implies that the construction of new EPRs might finally be postponed, that which would mean a loss of prospects for Areva and a catastrophe for the EPR program. It comments the commitment of EDF in the UK and outlines that the success of the development of new nuclear plants still depends on public subsidies which are not yet decided. The author considers that investments made by EDF in the USA seem rather speculative, and outlines that there are still financial issues and uncertainties like in the UK. The presence and activities of EDF and Areva in China are also commented, and more briefly for the rest of the world

Rosatom, the Russian who wants to dethrone Areva

Maincent, G.

2009-01-01

On March 3, 2009, Rosatom, the Russian atomic agency, signed an agreement with Siemens (Germany) for the creation of a common nuclear company. The objective is to become the World leader of the nuclear industry and to gain market shares on General Electric-Hitachi and Toshiba-Westinghouse. This is the spectacular consequence of the Siemens/Areva split from Areva NP, the reactor division of the Areva group. Rosatom gathers 89 civil nuclear companies inside the Atomenergoprom entity and is going to benefit from Siemens' know-how in the domains of instrumentation and control systems and reactors operation. Thanks to this alliance, the volume of Atomenergoprom's activities should grow up rapidly in particular in central and eastern Europe and more particularly in emerging countries. (J.S.)

Export Control in the AREVA Group

International Nuclear Information System (INIS)

Zero, S.

2013-01-01

After the Second World War the nuclear technology was mostly considered inappropriate for the export. It remains strictly regulated today, but the development of the civil applications urged states to facilitate the peaceful uses while establishing a strict control in the domains of the internal security and the nuclear proliferation. AREVA decided to set up an Export Control program applied to all the products and in all the countries where the group operates. AREVA can export products or make transfer of technology considered as sensitive for the non-proliferation and the risks linked to the terrorism. This sensitiveness results from the nature of the products or from the country of destination and in certain cases both of them. AREVA has set up an Export Control program and an interactive e-learning training within the Group to make exports of sensitive products, raw materials and technologies more secure. The subject is rather complex, the regulations are constantly evolving, and becoming familiar with them is necessarily a gradual process, but it must be made in-depth, hence the idea of regular training sessions. The implementation of the Export Control in the AREVA Group declines in four fundamental stages: -) Policy and procedure; -) Appointment of Export Control Officers (ECO); -) Training; and -) Audit and Self Assessment. The training program is composed by the following elements: Ethics (Value Charter) of the Group, Non-proliferation, international regulations and more particularly those that are applicable in Europe (Germany and France) and in the United States. Particular attention is devoted to the Export Control practice in China, Japan and India. (A.C.)

Wind power: Areva acquires a 51% stake in Multibrid

International Nuclear Information System (INIS)

2007-01-01

AREVA announced the acquisition of a 51% stake in Multibrid, a designer and manufacturer of multi-megawatt off-shore wind turbines based in Germany. With this acquisition, AREVA has entered into a joint venture with Prokon Nord, a German off-shore wind turbine and biomass plant developer and current owner of Multibrid. This transaction values Multibrid at euro 150 million. AREVA plans to rapidly further develop Multibrid's activities by giving the company access to its industrial resources, financial base and international commercial network. In return, Multibrid will provide AREVA with its leading-edge technology which, developed for 5 MW turbines, can achieve a very high output while reducing operating costs thanks to a simplified maintenance system. With this stake in Multibrid, AREVA aims to increase its presence on the offshore wind market that meets land settlement requirements and that should grow significantly in the years to come (from 300 MW in Europe today to an expected 1400 MW by 2011). As an exclusive supplier of Prokon Nord, Multibrid will participate in projects such as Borkum West (30 MW), the first offshore project in Germany, Borkum West 2 (400 MW), and Cote d'Albatre (105 MW), the first offshore wind farm project in France. The stake in Multibrid strengthens AREVA's strategic positioning on the CO 2 -free energy market, thanks to complementary solutions ranging from nuclear technologies to renewables. A number of recent achievements illustrate this strategy: - bio-energy (crucial energy supply in numerous rural areas): delivery of turnkey biomass power plants; ongoing construction of 10 plants in India, Thailand and Brazil; future development plans in fast-growing regions, such as Latin America; - wind power: Multibrid adds to the Group's stake in REpower and to its partnership with Suzlon for which AREVA is the number one supplier of transmission and distribution solutions for wind power; - hydrogen and fuel cells: design and manufacture of

Ramp-up - Areva Resources Canada Inc. 2015 annual sustainability review

International Nuclear Information System (INIS)

2016-01-01

Areva Resources Canada Inc. is a subsidiary of the Areva group. 2015 was the first full year of production at McClean Lake operation after four years of care and maintenance without production. A record-breaking 11.3 million pounds of uranium concentrate was produced at the McClean Lake mill in 2015, well above targets and up from a past maximum output of 6.5 million pounds. Areva's share of 2015 production at the mill totaled 4.2 million pounds. The substantial rise in output at McClean Lake is a direct result of Areva's upgrade and expansion work at the mill and the higher grade ore coming from its partnership with the Cigar Lake mine. With the upgrade, McClean Lake family has grown to 330 permanent employees with many more hired to complete specific projects. With the joint venture partnerships in the McArthur River mine and Key Lake mill, Areva's share of uranium concentrate production reached 12.9 million pounds. Despite the many successes, the fires that burned through northern Saskatchewan early in the summer of 2015 threatened the local communities

AREVA 2010 annual results

International Nuclear Information System (INIS)

2010-01-01

Areva's 44-billion euro backlog at the end of 2010 gives the group excellent visibility, enabling it to confirm its outlook for 2012: 12 billion euros in revenue, double-digit operating margin and significantly positive free operating cash flow. Revenue rose by 575 million euros in 2010, or 6.7%, in comparison to 2009 and operating income excluding particular items improved by 201 million euros, nearly 2 points of revenue. In the past two years, Areva has raised 7.1 billion euros and secured its liquidity to ensure its development. In 2011, Areva is going to simplify the group's capital structure by listing ordinary shares of AREVA. At that time, the group may launch the employee share-holding plan, something it has ardently sought for several years as a way for its employees to share in AREVA's growth. The consolidated backlog stood at 44.204 billion euros at December 31, 2010, up 2.0% compared with that at December 31, 2009. The group's consolidated revenue came to 9.104 billion euros in 2010, up 6.7% on a reported basis and 5.1% like-for-like compared with 2009. Excluding particular items, operating income rose by 1.9 point, going from 3.9% in 2009 to 5.8% in 2010, giving operating income of 532 million euros (331 million euros in 2009). Net income attributable to equity owners of the parent came to 883 million euros in 2010, an increase of 331 million euros compared with 2009. Operating cash flow before capex was 923 million euros, an increase of 548 million euros compared with 2009, when it was 375 million euros, due to the visible improvement in EBITDA and working capital requirement. The change in gross capex (excluding acquisitions) from 1.780 billion euros in 2009 to 1.966 billion euros in 2010 is due to the ramp-up of construction programs, particularly in Enrichment. In 2010, almost 60% of the group's capital spending was on sites in France. The acquisitions made in Renewable Energies in 2010 in the amount of 210 million euros (100% of Ausra and the

2007-01-01

AREVA and UraMin Inc. ('UraMin') entered on June 15, 2007 into an agreement in respect of AREVA's friendly cash offer for 100% of the share capital of UraMin. UraMin is listed in London (AIM) and Toronto (TSX). AREVA (Euronext Paris) already owns 5.5% of UraMin's share capital. This cash offer of AREVA will be made through its indirect wholly-owned subsidiary CFMM Development ('AREVA') based on a price of US$ 7.75 per UraMin share. The total offer consideration amounts to more than USD 2.5 billion for 100% of the fully diluted share capital of UraMin. This represents a premium of 21% over UraMin 20-day weighted average trading price ending on June 8, 2007. The UraMin Board of Directors, after consulting with its financial advisors, has determined that the offer is fair and in the best interest of the UraMin shareholders and it has resolved to recommend acceptance of the Offer. BMO Capital Markets has provided an opinion that the offer is fair, from a financial point of view, to the UraMin shareholders. In connection with the offer, all directors and certain other shareholders representing approximately 25% of the outstanding UraMin shares (calculated on a fully diluted basis) have entered into lock-up agreements with AREVA pursuant to which they have agreed to tender all their UraMin shares to AREVA's offer. The support agreement entered into between AREVA and UraMin provides for, among other things, in case a superior proposal is accepted by UraMin, a right to match in favour of AREVA. The support agreement also includes a break up fee in favour of AREVA of US$ 75 million under certain circumstances. Concurrently with the closing of the proposed offer, UraMin will declare a dividend payable in shares of the capital of Niger Uranium Limited held by UraMin (where permitted by law) or a cash equivalent of the value of such shares

AREVA Projects is one of the 6 business units of New AREVA and it is dedicated to engineering works in a vast fan of activities from mining to waste management via uranium chemistry and nuclear fuel recycling. AREVA projects has opted for innovation to improve performance. Since 2012 virtual reality has been used through the creation of a room equipped with a high-definition screen and stereoscopic goggles. At the beginning virtual reality was used to test and validate procedures for handling equipment thanks to a dynamical digital simulation of this equipment. Now virtual reality is massively used to validate the design phase of projects without having to fabricate a physical mock-up which saves time. The next step in the use of virtual reality is the implementation of a new version of devices like helmets, gloves... that will allow a better interaction with the virtual world. The continuously increasing of computer power is always pushing back the limits of what is possible in virtual reality. (A.C.)

2010-01-01

Because of the perspectives of new builds, a significant increase in the number of design, construction and management personnel working in AREVA, their clients and sub-contractors has been estimated for the next future. In order to cope with the challenge to integrate newly hired people quickly and effectively into the AREVA workforce, a project - 'Training Task Force (TTF)' - was launched in 2008. The objective was to develop introductory and advanced courses and related tools harmonized between AREVA Training Centers in France, Germany and USA. First, a Global Plants Introductory Session (GPIS) was developed for newly hired employees. GPIS is a two weeks training course introducing in a modular way AREVA and specifically the activities and the reactors technical basics. As an example, design and operation of a nuclear power plant is illustrated on EPRTM. Since January 2009, these GPIS are held regularly in France, Germany and the US with a mixing of employees from these 3 regions. Next, advanced courses for more experienced employees were developed: - Advanced EPR TM , giving a detailed presentation of the EPR TM reactor design; - Codes and Standards; - Technical Nuclear Safety. Finally, feasibility studies on a Training Material Management (TMM) system, able to manage the training documentation, and on a worldwide training administration tool, were performed. The TTF project was completed mid of 2009; it transferred their recurrent activities to a new AREVA training department. This unit now consists of the French, German and US Reactors Training Centers. In particular, all courses developed by the TTF are now implemented worldwide with an opening to external trainees. The current worldwide course catalogue includes training courses for operation and maintenance personnel as well as for managers, engineers and non technical personnel of nuclear operators, suppliers, safety authorities and expert organizations. Training delivery is supported effectively by tools

During its meeting held on December 12, 2011, devoted in particular to the examination of the 2011 closing estimates, the AREVA Executive Board indicated that it expected to book a provision of 1.46 billion euros (2.025 billion US dollars) in the company's accounts for fiscal year 2011 for impairment of assets for the reporting entity UraMin, a mining company acquired by AREVA in 2007, which, given the provision booked in 2010 (426 million euros), brings the value of these assets on the AREVA balance sheet down to 410 million euros. Given the size of these provisions, the Supervisory Board decided to make three of its members, meeting as an ad hoc committee, in charge of analyzing the terms of acquisition of this company, as well as the key decisions made in this reporting entity up to 2011 and, based on the outcome of these analyses, to recommend to it any appropriate measures in AREVA's interest. This committee reported on its work during the Supervisory Board meeting held on February 14, 2012. In light of this report, the Supervisory Board found that the fairness and reliability of the financial statements of previous years were not in question. Nevertheless, considering the malfunctions raised, the Board considers it appropriate to thoroughly review AREVA's governance in order to ensure that decisions concerning large acquisitions or investments be reviewed and validated in the future under conditions ensuring better legal and financial security and enabling a more transparent dialogue between management and the Supervisory Board. It thus asked the Executive Board to recommend, at the next General Meeting of Shareholders, that the by-laws of the company be modified to make the Supervisory Board's prior approval of investments, stake acquisitions and acquisitions mandatory above a threshold of 20 million euros. It also decided to set up a business ethics committee within the Supervisory Board responsible for ensuring that rules of conduct are

Full system decontamination. AREVAs experience in decontamination prior to decommissioning

International Nuclear Information System (INIS)

Topf, Christian

2010-01-01

Minimizing collective radiation exposure and producing free-release material are two of the highest priorities in the decommissioning of a Nuclear Power Plant (NPP). Full System Decontamination (FSD) is the most effective measure to reduce source term and remove oxide layer contamination within the plant systems. FSD is typically a decontamination of the primary coolant circuit and the auxiliary systems. In recent years AREVA NP has performed several FSDs in PWRs and BWRs prior to decommissioning by applying the proprietary CORD copyright family and AMDA copyright technology. Chemical Oxidation Reduction Decontamination or CORD represents the chemical decontamination process while AMDA stands for Automated Mobile Decontamination Appliance, AREVA NPs decontamination equipment. Described herein are the excellent results achieved for the FSDs applied at the German PWRs Stade in 2004 and Obrigheim in 2007 and for the FSDs performed at the Swedish BWRs, Barsebaeck Unit 1 in 2007 and Barsebaeck Unit 2 in 2008. All four FSDs were performed using the AREVA NP CORD family decontamination technology in combination with the AREVA NP decontamination equipment, AMDA. (orig.)

The AREVA group recorded accelerated growth and increased profitability in 2007, meeting both of its objectives for the year. The group made strategic inroads in fast growing markets. AREVA's integrated model met with record success in China, where GGNPC acquired two EPR nuclear islands in a combined order including both the reactors and the fuel, and the creation of a joint venture in engineering. Its T and D division was awarded the largest contract of its history in Qatar, making it the leader in a region where T and D was not even present a few years ago. For more than three years, AREVA has built up its capacity to meet surging demand in the nuclear power and T and D markets through an active policy of research and development and by capitalizing on the diversity and strength of its partnerships. Areva hired 8,600 people in 2006 and 11,500 people in 2007; this represents an investment in recruitment, training and integration of approximately euro 200 million per year. For 2008, the group foresees a further increase in its backlog, sales revenue and operating income. The Areva Group financial statements for 2007 are summarized below: - Backlog: euro 39.8 billion, up 55%; - Sales revenue: euro 11.9 billion, up 9.8% (up 10.4% like-for-like); - Operating income: euro 751 million, i.e. 6.3% operating margin, up 2.6 points compared with 2006; - Net income attributable to equity holders of the parent: euro 743 million (euro 20.95 per share), up from euro 649 million in 2006 (euro 18.31 per share); - Net debt: euro 1.954 billion, linked to the acquisition of UraMin; - Dividend: euro 6.77, to be proposed to the Annual General Meeting of Shareholders convening on April 17, 2008.

The expected growth of demand in nuclear power stations and technologies compelled the French-German company Areva NP to look for other possibilities for expansion. The company belongs to the French energy concern, Areva, which employs almost sixty thousand people worldwide and which last year achieved revenues of ten billion EUR. A joint venture between the French company and the German company Siemens - Areva NP - designs and manufactures software and hardware for security and automation technologies in nuclear power stations. Areva NP Controls, a subsidiary of the company, has been operating in Bratislava from 1 July. The plan is that Slovak engineers will design hardware and software to be used in nuclear power station security systems around the world. The decision to open an engineering office in Bratislava was made after the management at the German head office realised the need for three hundred new engineers. T his many quality people are not available in Germany right now , said Franz Hilbert, the boss of the Slovak subsidiary. The company decided between the Czech Republic, Russia and India. In the end, Bratislava was chosen. F. Hilbert added that Slovakia has many quality people, but that lower labour costs also played a role in the decision-making process. The company plans to employ half of the required three hundred engineers in Bratislava and the remainder in Erlangen. About a dozen engineers are currently working in this Slovak company, some of whom are currently borrowed from partners. The view is that within five years about one hundred engineers will work in Slovakia under domestic management. According to F. Hilbert, the meeting of the Slovak and German cultures is trouble free, even though some differences can still be seen. 'We are better in planning and in fulfilling those plans, while the Slovaks are great at improvising. We are able to complement and learn from each other', said F. Hilbert. (authors)

Following the recent opening of its new gas-insulated switchgear factory last month in Suzhou, China, AREVA's Transmission and Distribution (T and D) division has announced additional actions to increase its market share in the country. The division has just signed an agreement to form a 50/50 joint venture with the Chinese company, Sunten Electric Co. Ltd., a leading manufacturer of distribution transformers, whose 2006 annual sales reached circa euro 120 million. Through this joint venture, AREVA T and D will become No 1 in China for dry-type transformers, Sunten Electric Co. Ltd.'s specialization. AREVA T and D has also established a partnership with the China Electric Power Research Institute (C-EPRI), a leading Chinese organization specialized in electrical technologies. Under the agreement, C-EPRI will be the official licensee for AREVA T and D's H-400 high-voltage direct current (HVDC) Thyristor valves in China. The partnership will enable AREVA T and D to enter the fast-growing domestic HVDC market. The T and D sector in China represents 24% of the worldwide transmission and distribution market. AREVA T and D's turnover in China, where demand for T and D equipment is growing strongly, should significantly contribute to the division's objective to reach euro 5 billion in sales by 2010

Because of the perspectives of new builds, a significant increase in the number of design, construction and management personnel working in AREVA, their clients and sub-contractors has been estimated for the next future. In order to cope with the challenge to integrate newly hired people quickly and effectively into the AREVA workforce, a project - 'Training Task Force (TTF)' - was launched in 2008. The objective was to develop introductory and advanced courses and related tools harmonized between AREVA Training Centers in France, Germany and USA. First, a Global Plants Introductory Session (GPIS) was developed for newly hired employees. GPIS is a two weeks training course introducing in a modular way AREVA and specifically the activities and the reactors technical basics. As an example, design and operation of a nuclear power plant is illustrated on EPRTM. Since January 2009, these GPIS are held regularly in France, Germany and the US with a mixing of employees from these 3 regions. Next, advanced courses for more experienced employees were developed: - Advanced EPR{sup TM}, giving a detailed presentation of the EPR{sup TM} reactor design; - Codes and Standards; - Technical Nuclear Safety. Finally, feasibility studies on a Training Material Management (TMM) system, able to manage the training documentation, and on a worldwide training administration tool, were performed. The TTF project was completed mid of 2009; it transferred their recurrent activities to a new AREVA training department. This unit now consists of the French, German and US Reactors Training Centers. In particular, all courses developed by the TTF are now implemented worldwide with an opening to external trainees. The current worldwide course catalogue includes training courses for operation and maintenance personnel as well as for managers, engineers and non technical personnel of nuclear operators, suppliers, safety authorities and expert organizations. Training delivery is supported

In 2011, AREVA's consolidated revenue came to 8.872 billion euros, down slightly (-2.6%) compared with 2010 (-1.2% like for like). The decrease in revenue in nuclear operations was partially offset by significant growth in the renewable energies business. Foreign exchange and changes in the scope of consolidation had respectively a negative impact of 113 million euros and 16 million euros over the period. Revenue totaled 2.922 billion euros in the fourth quarter of 2011, stable compared with the fourth quarter of 2010 (-0.5% on a reported basis and -0.5% like for like). Foreign exchange had a negligible impact during the period. Led by nuclear operations, the group's backlog was 45.6 billion euros at December 31, 2011, up 3.1% year on year and 6.7% in relation to September 30, 2011. Order cancellations since Fukushima were limited to 464 million euros as of December 31, 2011. In accordance with the requirements of IFRS 8, AREVA's business segment information is presented for each operating Business Group (BG), which is the level of information examined by the group's governance bodies. Subsequent to the establishment of a subsidiary combining all of the group's mining operations, data for the Mining Business Group are now reported separately from those of the Front End Business Group. Data used for comparisons with 2010 were restated to reflect this new organization.

South Africa opted to develop its electricity production sector in a safe and competitive manner using CO 2 free technologies in order to support its economic and social growth. The country's ambitious energy program aims to create a lasting nuclear sector generating 20 GW of electricity by 2025 mainly from super modern water reactors and PBMRs. South Africa wishes to become a world player in the nuclear energy field, thus reinforcing its position as one of the major world producers of energy. In the strategic plan for the development of a national nuclear policy unveiled in July 2007, the government's objective is to create the suitable conditions for a nuclear industry based on the most modern technologies and promote an ambitious new builds construction program. By 2030, nuclear energy should provide 30% of electricity in South Africa, from a fleet of PWRs and PBMRs. In 2007, ESKOM's Board of Directors approved a plan to re-launch the construction of electrical plants in South Africa, to reach around 80 GW by 2025 and including the construction of an additional 20 GW of nuclear-based capacity. This nuclear revival program provides for the construction of PWR nuclear power plant generating a total of 3 GWe to 3,5 GWe, to go online as of 2016, and the consideration of a fleet of PWR power plants up to 20,000 MWe in total to gradually go on line through 2025. Five sites have already been identified for the new power stations and the nuclear company to build the power plants will be selected in 2008. AREVA's Evolutionary Power Reactor (EPR) and Westinghouse's AP 1000 have been pre-selected. The Government aims to achieve the objective of encourage the participation of Public entities such as the South African Nuclear Energy Corporation (NECSA) in the uranium value chain. Such public entities shall be used to store the secured uranium supplies, as well as participate in the local beneficiation. NECSA, as the state's body responsible for research and development in

EPR by Areva. The path of greatest certainty

International Nuclear Information System (INIS)

2008-01-01

AREVA's Evolutionary Power Reactor (EPR) is the first Generation III+ reactor design currently being built to answer the world's growing demand for clean and reliable electricity generation. Already under construction in Finland, France and China, the EPR is also being considered by America, United Kingdom, South Africa and other countries for the development of their nuclear fleet. The EPR is now clearly destined to become the mainstay of standardized, efficient reactor fleets around the globe. AREVA's EPR incorporates unbeatable know-how provided by an uninterrupted track record of reactor building activities and backed by decades of feedback experience from operating PWRs, including the most recent. The EPR is a Franco-German initiative which benefited from the stringent scrutiny of safety authorities from both countries, at each stage of the project. The EPR has already secured construction licenses from two of the world's most demanding safety authorities in France and Finland and is currently in line for a design certification and a combined construction and operating license (COL) in the USA. It is also taking part in the licensing process recently launched in the United Kingdom. Europe's leading utilities have granted the EPR their approval under the 'European Utilities Requirements' and have further expressed individual interest in the design and performance of the EPR for their businesses. AREVA is the only Gen III+ reactor constructor in the world with ongoing building experience. To date, AREVA is the only vendor who has the necessary field experience that future customers can benefit: - Detailed design completed; - Experience feedback from 87 PWR; - 3 projects going on; - Continuous PWR experience in design and construction. Close to 100% of the EPR primary circuit heavy components are sourced directly from AREVA's integrated plants. Engineering, manufacturing, services and fuel cycle management are totally integrated and mastered by AREVA. From its

One year after launching Areva's Action 2016 strategic plan, the first results are in. AREVA is ahead of schedule in executing its recovery plan. While pursuing its efforts in the management of a few difficult projects (such as OL3), Areva group was able to return to a virtuous performance cycle rooted in strong growth in nuclear order intake and good progress on its cost reduction program. Commercially, despite the difficult economic environment, AREVA was able to capitalize on its leadership in the installed base and on its long-term partnerships with strategic customers, beginning with EDF, with which AREVA renewed a confident and constructive working relationship. Areva has secured 80% of its objective of one billion euros of savings by the end of 2015 to improve its competitiveness. The group also continued efforts to optimize working capital requirement and control the capital expenditure trajectory. Together, these results enabled AREVA to exceed the objectives set for 2012 for two key indicators of its strategic plan: EBITDA and free operating cash flow. Nearly 60% of the 2.1 billion euros devoted to capital expenditures for future growth in 2012 were funded by operations, a quasi-doubled share compared to 2011. Areva's floor target for asset disposals was achieved one year ahead of schedule, also helping the Group to control its net debt, which remained below 4 billion euros. In 2013, Areva is continuing to implement the Action 2016 plan to keep its turnaround on track. In summary: - Backlog renewed over the year 2012 to euro 45.4 bn thanks to the increase in nuclear order intake; - Sales revenue growth: euro 9.342 bn (+5.3% vs. 2011), led by nuclear and renewables operations; - Very sharp upturn in EBITDA: euro 1.007 bn (+euro 586 m vs. 2011) - Very net improvement in free operating cash flow: -euro 854 m (+euro 512 m vs. 2011); - Back to positive reported operating income: euro 118 m (+euro 1.984 bn vs. 2011); - 2012-2013 floor target for asset disposals

During its meeting held on December 12, 2011, devoted in particular to the examination of the 2011 closing estimates, the AREVA Executive Board indicated that it expected to book a provision of 1.46 billion euros (2.025 billion US dollars) in the company's accounts for fiscal year 2011 for impairment of assets for the reporting entity UraMin, a mining company acquired by AREVA in 2007, which, given the provision booked in 2010 (426 million euros), brings the value of these assets on the AREVA balance sheet down to 410 million euros. Given the size of these provisions, the Supervisory Board decided to make three of its members, meeting as an ad hoc committee, in charge of analyzing the terms of acquisition of this company, as well as the key decisions made in this reporting entity up to 2011 and, based on the outcome of these analyses, to recommend to it any appropriate measures in AREVA's interest. This committee reported on its work during the Supervisory Board meeting held on February 14, 2012. In light of this report, the Supervisory Board found that the fairness and reliability of the financial statements of previous years were not in question. Nevertheless, considering the malfunctions raised, the Board considers it appropriate to thoroughly review AREVA's governance in order to ensure that decisions concerning large acquisitions or investments be reviewed and validated in the future under conditions ensuring better legal and financial security and enabling a more transparent dialogue between management and the Supervisory Board. It thus asked the Executive Board to recommend, at the next General Meeting of Shareholders, that the by-laws of the company be modified to make the Supervisory Board's prior approval of investments, stake acquisitions and acquisitions mandatory above a threshold of 20 million euros. It also decided to set up a business ethics committee within the Supervisory Board responsible for ensuring that rules of conduct are properly applied

South Africa opted to develop its electricity production sector in a safe and competitive manner using CO{sub 2} free technologies in order to support its economic and social growth. The country's ambitious energy program aims to create a lasting nuclear sector generating 20 GW of electricity by 2025 mainly from super modern water reactors and PBMRs. South Africa wishes to become a world player in the nuclear energy field, thus reinforcing its position as one of the major world producers of energy. In the strategic plan for the development of a national nuclear policy unveiled in July 2007, the government's objective is to create the suitable conditions for a nuclear industry based on the most modern technologies and promote an ambitious new builds construction program. By 2030, nuclear energy should provide 30% of electricity in South Africa, from a fleet of PWRs and PBMRs. In 2007, ESKOM's Board of Directors approved a plan to re-launch the construction of electrical plants in South Africa, to reach around 80 GW by 2025 and including the construction of an additional 20 GW of nuclear-based capacity. This nuclear revival program provides for the construction of PWR nuclear power plant generating a total of 3 GWe to 3,5 GWe, to go online as of 2016, and the consideration of a fleet of PWR power plants up to 20,000 MWe in total to gradually go on line through 2025. Five sites have already been identified for the new power stations and the nuclear company to build the power plants will be selected in 2008. AREVA's Evolutionary Power Reactor (EPR) and Westinghouse's AP 1000 have been pre-selected. The Government aims to achieve the objective of encourage the participation of Public entities such as the South African Nuclear Energy Corporation (NECSA) in the uranium value chain. Such public entities shall be used to store the secured uranium supplies, as well as participate in the local beneficiation. NECSA, as the state's body responsible

Dose constraint implementation in AREVA group: an optimization tool

AREVA offers customers reliable technology solutions for CO 2 free power generation and electricity transmission and distribution. The group counts 68000 employees worldwide and for its nuclear activities there are about 33.000 people who work under ionizing radiation. Risk management and prevention is one of the ten engagements of the sustainable development policy of AREVA, to establish and maintain the highest level of nuclear and occupational safety in all of the group's operations to preserve public and worker health, and to protect the environment. The implementation of these engagements is founded on a voluntary continuous improvement program, AREVA Way: objectives, common for the all entities, are laid down in the policies documents. Indicators are defined and a common reporting method for each indicator and the result of performance self-assessment is set up. AREVA chose to federate the whole of the nuclear entities around a common policy, the Nuclear Safety Charter, implemented at the beginning of 2005. This charter sets up principles of organization, action and engagements of transparency. Regarding radiation protection, the Charter reaffirms the engagement to limit in the installations of the group, at a level as low as reasonably possible, the exposure of the workers, through the implementation of the ALARA principle and the implementation of a continuous improvement policy. This approach, basically different from the simple respect of imposed limits, radically modifies the dynamics of progress. In the activities of engineering, the optimization of protection against radiation is also integrated in the design, by taking account the experience feedback of the operational activities. This determination of constraints is taken on all levels of the organization. Thus sustainable development performance indicators and especially those relating to protection against radiation are discussed between the managers in charge of Units Business and the Top managers

AREVA's Evolutionary Power Reactor (EPR) is the first Generation III+ reactor design currently being built to answer the world's growing demand for clean and reliable electricity generation. Already under construction in Finland, France and China, the EPR is also being considered by America, United Kingdom, South Africa and other countries for the development of their nuclear fleet. The EPR is now clearly destined to become the mainstay of standardized, efficient reactor fleets around the globe. AREVA's EPR incorporates unbeatable know-how provided by an uninterrupted track record of reactor building activities and backed by decades of feedback experience from operating PWRs, including the most recent. The EPR is a Franco-German initiative which benefited from the stringent scrutiny of safety authorities from both countries, at each stage of the project. The EPR has already secured construction licenses from two of the world's most demanding safety authorities in France and Finland and is currently in line for a design certification and a combined construction and operating license (COL) in the USA. It is also taking part in the licensing process recently launched in the United Kingdom. Europe's leading utilities have granted the EPR their approval under the 'European Utilities Requirements' and have further expressed individual interest in the design and performance of the EPR for their businesses. AREVA is the only Gen III+ reactor constructor in the world with ongoing building experience. To date, AREVA is the only vendor who has the necessary field experience that future customers can benefit: - Detailed design completed; - Experience feedback from 87 PWR; - 3 projects going on; - Continuous PWR experience in design and construction. Close to 100% of the EPR primary circuit heavy components are sourced directly from AREVA's integrated plants. Engineering, manufacturing, services and fuel cycle management are totally

The 2015 results illustrate the progress AREVA made in 2015 and open up favorable prospects for 2016 and the following years in view of its fundamentals. The group's competitiveness plan had a very positive impact on its costs and cash, despite the heavy net loss situation which continues and in a market environment that remained difficult in 2015. Half of this loss of 2 billion Euro is due to additional provisions for OL3 and half to provisions for restructuring and impairment related to market conditions. Concerning the group's liquidity, 2016 is funded and the capital increase which will be launched in the coming months will enable AREVA to gradually regain the group's positive profile. A new phase awaits the Group in 2016 with clarity and confidence in the implementation of the restructuring announced in 2015 and in particular the autonomy of AREVA NP and the creation of New AREVA

Areva - First half 2008 sales revenue

International Nuclear Information System (INIS)

2008-01-01

As of June 30, 2008, AREVA's backlog stood at 38.1 billion euro, for 13.6% growth since June 30, 2007, with 9.9% growth in Nuclear and 40.7% growth in Transmission and Distribution. In Nuclear, the backlog came to 32.3 billion euro as of the end of June 2008. In the front end of the cycle, AREVA signed multi-year contracts in the first half of the year with Japanese and American utilities and with EDF, for a combined total of more than 1 billion euro. Of note in the back end of the cycle is the contract AREVA signed with the U.S. Department of Energy to build a MOX fuel fabrication facility. In Transmission and Distribution, the backlog came to 5.8 billion euro as of the end of period. A total of 3.2 billion euro in orders was booked in the first half, an increase of 20.0% year-on-year. The division won several important contracts, most notably a contract with Dubai Electricity (more than 130 million euro), a contract with National Grid and RTE for the renovation of the IFA 2000 grid interconnection between France and Great Britain (more than 60 million euro), and, in the industrial field, a contract with Rio Tinto Alcan (close to 65 million euro). The group cleared revenue of 6.2 billion euro in the first half of 2008, up 14.8% (+16.4% like-for-like) compared with the first half of 2007. Sales outside France were up 14.3% to 4.2 billion euro or 68.6% of total sales; the latter were stable compared with the first half of 2007. All businesses were up, with growth of 15.9% in Nuclear operations (+19.1% LFL1) - particularly in Reactors and Services (+31.3% LFL1) - and 13.0% growth in Transmission and Distribution operations (+12.0% LFL T 1). Foreign exchange had a negative impact of 155 million euro, primarily due to the change in the U.S. dollar in relation to the euro. Changes in the consolidated group had a positive impact of 97 million euro, mainly reflecting acquisitions in the Transmission and Distribution division and in Renewable Energies. Sales revenue for

Faced with obvious energy procurement security needs and the increasing concern about global warming, many countries are making a lucid analysis of their energy situation and reconsidering the multiple assets of nuclear energy. After the European Commission's Green Paper evaluation which was endorsed by the European Parliament, the United States gave a strong signal to the whole world by deciding to extent the operating life time of its existing NPPs and by envisioning the construction of new ones. In Asia, here in Korea, and in Japan, the People's Republic of China, Taiwan, large-scale nuclear power plant programs are being pursued. It was in this context, with the aim of ever-greater competitiveness, that the AREVA group was conceived. The aim is for all our skills to have a higher profile on the international markets, so that we are in a stronger position to develop a leadership in our two main high tech sectors of interconnect - electronics and nuclear. In the nuclear sector, the pooling of the Cogema and Framatome ANP forces is enabling AREVA to offer a comprehensive service package ranging from uranium mining to decommissioning, encompassing the design and construction of plants and their fuel; AREVA's experience is grounded in unequalled know-how. Further, with the CEA, a multidisciplinary research organization in charge of anticipating the emerging technologies, as a close partner, AREVA has a unique strategic vision. With this set-up, AREVA has the financial resources it needs to forge the alliances necessary for its development, so that it can best confront international competition and meet the requirements of its customers world-wide

In 2002 the turnover of the Areva group has fallen by 7,1 % from 8,90 milliard euros in 2001 to 8,26 milliard euros. This fall breaks up into -3,6 % for the nuclear sector and -20,7 % for connector engineering. The sharp drop for connector engineering is not surprising and is attributed to the fact that in 2002 there was no revival of business in the market of communication equipment. (A.C.)

Over the past ten years, AREVA has performed D and D operations on a wide range of nuclear sites, such as Marcoule and La Hague recycling plants, to Cadarache MOX fuel fabrication plant or Veurey and Annecy metallic Uranium machining plants. Each site is different from the other but some lessons can be shared through this D and D portfolio. In that respect, knowledge management is one of AREVA D and D Technical Department main missions. Four illustrations demonstrate the interest of knowledge share. Waste management is one of the key activities in D and D; It requires a specific characterization methodology, adapted logistics, and optimized waste channels, all of which have been developed over the years by AREVA teams on the site of Marcoule while they are rather new to La Hague, whose main activity remains fuel reprocessing despite the launch of UP2 400 D and D program. The transfer of know how has thus been organized over the past two years. Plasma cutting has been used extensively in Marcoule for years, while prohibited on the site of La Hague following questions raised about the risks associated wit Ruthenium sublimation. La Hague Technical Department has thus developed an experimental protocol to quantify and contain the Ruthenium risk, the result of which will then be applied to Marcoule where the Ruthenium issue has appeared in recent operations. Commissioning and operating fission products evaporators is a rather standard activity on UP2 800 and UP3, while the associated experience has been decreasing in Marcoule following final shutdown in 1998. When the French atomic Energy commission decided to build and operate a new evaporator to concentrate rinsing effluents prior to vitrification in 2009, AREVA La Hague operators were mobilized to test and commission the new equipment, and train local operators. Concrete scabbling is the final stage prior to the free release of a nuclear facility. In the context of Veurey and Annecy final cleanup and declassification

The Actiflo-Rad TM system successfully contributed to treat the contaminated wastewaters from the damaged Fukushima Daiichi nuclear power plant. The decontamination system jointly designed by AREVA and Veolia Water treated about 77 500 m 3 of high activity wastewater (∼10 6 Bq/cm 3 ), combining radionuclides adsorbents developed by AREVA and the know-how of Veolia in water treatment for the settlement of the adsorbed radioactive elements, producing sludge with a weight concentration of 80 g/L. Both companies delivered the treatment facility quickly with an efficient joint organization - in a very complex environment. Assembled on Fukushima site - badly damaged by the tsunami following the earthquake of March 11 th - the system was designed, built and started in a record time of 2 month 1 / 2 , instead of several years in a classical nuclear engineering project. The Actiflo-Rad TM was a key equipment to achieve a stable situation of reactors, allowing treated water to be reused for core cooling. Commissioned with the on-site support of Veolia experts, the system reduced by 10 000 the Cs-activity of the wastewater even with significant salt content (seawater diluted twice) at a flow-rate slightly below the design value of 50 m 3 /hr. The implemented technologies are already used separately on AREVA sites (la Hague, fuel reprocessing plant) and for many water treatment projects by Veolia all over the world (Actiflo TM and Multiflo TM processes, using lamellar settling devices - in addition, the first one making use of micro-sand for a better floc quality). The complete treatment process selected by TEPCO features a physico-chemical treatment and water desalination, in five steps. After de-oiling, wastewater is primarily decontaminated through zeolite columns (Kurion process). This pre-decontaminated water is then treated on the AREVA-Veolia two stages system; at each stage, more than 30 minutes contact time with radionuclides adsorbents is needed, adsorbed

AREVA NP decontamination concept for decommissioning. A comprehensive approach based on over 30 years experience

International Nuclear Information System (INIS)

Stiepani, Christoph

2011-01-01

Decontamination prior to Decommissioning and Dismantlement is imperative. Not only does it provide for minimization of personnel dose exposure but also maximization of the material volume available for free release. Since easier dismantling techniques in lower dose areas can be applied, the licensing process is facilitated and the scheduling and budgeting effort is more reliable. The most internationally accepted approach for Decontamination prior to Decommissioning projects is the Full System Decontamination (FSD). FSD is defined as the chemical decontamination of the primary cooling circuit, in conjunction with the main auxiliary systems. AREVA NP has long-term experience with Full System Decontamination for return to service of operating nuclear power plants as well as for decommissioning after shutdown. Since 1976, AREVA NP has performed over 500 decontamination applications and, from 1986, Decontaminations prior to Decommissioning projects which comprise virtually all NPP designs and plant conditions were performed: NPP designs: HPWR, PWR, and BWR by AREVA, Westinghouse, ABB and GE. Decontaminations performed shortly after final shutdown or several years later, and even after re-opening Safe Enclosure. High Alpha inventory and or low gamma/alpha ratio. Main Coolant chemistry (e.g., with and without Zn injection during operation). Fifteen Decontaminations prior to Decommissioning Projects have been performed successfully to date and the sixteenth FSD is now in the detailed engineering phase and is scheduled to commence late 2010. AREVA NP has developed a fully comprehensive approach for decontamination based on the CORD® (Chemical Oxidation Reduction Decontamination) Family, applied using the in-house designed decontamination equipment AMDA TM (Automatic Modular Decontamination Appliance). Based on the vast experience of AREVA NP in the field of decontamination, the Decontamination Concept for Decommissioning was developed. This concept ensures that the

Cominak in Niger owns a large stock of high grade fines which cumulated originally from underground mining discharge water. This ore is too fine to be treated with the current process because it readily blocks the cloths of the belt filters. Cominak plans to build a Resin-In-Pulp (RIP) plant. The RIP technology permits to recover U values without filtration. Some bench scale studies (at AREVA-SEPA) and two trial campaigns (on site) had been successfully conducted to implement the RIP process, which further allows, from economic point of view, a positive feasibility evaluation. As part of the Kiggavik Project managed by Areva Resources Canada (ARC), AREVA-SEPA is also being actively involved in developing a practical, cost-effective and environmentally sound process flowsheet. RIP technology has drawn significant attention due to the relatively low water consumption and capital cost. SEPA's experience with RIP technology together with the newer and better-performance resins makes this technology a viable choice. Three pilot campaigns have been accomplished at SEPA, which is believed to be of great help to reduce technical risk as well as capital risk in the decision making for Kiggavik project. (author)

Set up at the beginning of the site's operations, in 1962, the monitoring of the radiological environmental impact of the AREVA site of Tricastin has evolved over time to meet more specifically the multiple objectives of environmental monitoring: to prove the respect of the commitments required by the authorities, to be able to detect a dysfunction in the observed levels, to enable the assessment of impacts of industrial activities, to ensure the balance between environmental quality and the use made by the local population and to inform the public of the radiological state of the environment. Thousands of data were acquired on the radioactivity of all environmental compartments as well as on the functioning of local ecosystems. Today, the Network of Environmental Monitoring of AREVA Tricastin goes beyond the requirements of routine monitoring to provide innovative solutions for monitoring the radioactivity (especially for uranium) in the environment.

AREVA first half 2007 sales revenue

International Nuclear Information System (INIS)

2007-01-01

The AREVA group's backlog as of June 30, 2007 was euros 33.5 billion, up 31% compared with that of December 31, 2006. On average, the Group's backlog increased by more than 20% annually over the last three years. It is now at the highest level since AREVA was established in 2001. All divisions contributed to this performance: - The Front End division signed in particular a major enrichment contract with KHNP (South Korea), a fuel supply contract with EDF covering the 2008-2012 period and other significant contracts with Japanese and Swedish utilities. - The Reactors and Services division added the Flamanville 3 EPR, ordered by EDF, to the backlog. Flamanville 3 is AREVA's 100. reactor order. - The Back End division also concluded a major contract with Sogin to treat used fuel stored at Italian nuclear sites. - The Transmission and Distribution division continued to record strong growth. New orders were up 24% compared with the first half of 2006 (+25.1% like-for-like). Important contracts were signed in the Middle East, Russia and with large industrial users of electricity. First half 2007 sales revenue was up 6.7% (+6.4% like-for-like) to euros 5373 million, compared with euros 5036 million for the first half of 2006. Major developments in the first half of 2007 include: - Sales revenue was down 2.8% to euros 1342 million in the Front End division (-3.6% like-for- like) due to uneven distribution of deliveries in the Fuel business unfavorable during the period. This timing issue has no impact on projected annual growth. The division continues to benefit from a gradual price increase for long-term uranium supply contracts. - Sales revenue was up 4.8% to euros 1154 million in the Reactors and Services division (+3% like-for-like). The Services business unit, especially, was a major contributor to growth on all its markets after a 2006 fiscal year marked by a weak demand. The start of construction of a second EPR reactor for EDF, Flamanville 3, also contributed to

2007-01-01

The merger of the product portfolios of the former Siemens and Framatome fuel businesses gave rise to a new family of PWR products which combine the best features of the different technologies to enhance the main performance of each of the existing products. In this way, the technology of each of the three main fuel assembly types usually delivered by AREVA NP, namely Mark-BW TM , HTP TM and AFA 3G TM has been enriched by one or several components from the others which contributes to improve their robustness and to enhance their performance. The combined experience of AREVA's products shows that the ROBUST FUELGUARD TM , the HMP TM end grid, the MONOBLOC TM guide tube, a welded structure, M5 R material for every zirconium component and an upper QUICK-DISCONNECT TM are key features for boosting fuel assembly robustness. The ROBUST FUELGUARD benefits from a broad experience demonstrating its high efficiency in stopping debris. In addition, its mechanical strength has been enhanced and the proven blade design homogenizes the downstream flow distribution to strongly reduce excitation of fuel rods. The resistance to rod-to-grid fretting resistance of AREVA's new products is completed by the use of a lower HMP grid with 8 lines of contact to insure low wear. The Monobloc guide tube with a diameter maximized to strengthen the fuel assembly stiffness, excludes through its uniform outer geometry any local condition which could weaken guide tube straightness. The application of a welded cage to all fuel assemblies of the new family of products in combination with stiffer guide tubes and optimized hold-down assures each fuel assembly enhanced resistance to distortion. The combination of these features has been widely demonstrated as an effective method to reduce the risk of incomplete RCCA insertion and significantly reduce assembly distortion. Thanks to its enhanced performance, M5 alloy insures that all fuel assemblies in the family maintain their performance in all

2016-01-01

In the first quarter of 2016, AREVA generated consolidated revenue of 826 million euros, a decrease of 0.8% (-2.2% like for like) compared with the same period in 2015, due in particular to the schedule of uranium deliveries. Foreign exchange had a positive impact of 12 million euros over the period. At March 31, 2016, the group's backlog reached 33.6 billion euros, up sharply compared to December 31, 2015 (29 billion euros), and represented eight years of revenue. It reflects in particular multi-year commercial agreements signed with EDF in early 2016. The order intake for the first quarter of 2016 totaled 6.1 billion euros, a strong increase in relation to the first quarter of 2015 (0.3 billion euros)

AREVA invests 610 million euro in new uranium conversion plants

International Nuclear Information System (INIS)

2007-05-01

AREVA today announced the launch of the Comurhex II project which will see the group build new uranium conversion facilities on the Malvesi site in Narbonne and Tricastin. Through this 610 million euro investment, AREVA aims to maintain its position as world no. 1 for conversion within a context of global nuclear energy. COMURHEX II integrates technological innovations from major R and D programs and return of experience from processes in operation for over forty years. Nuclear safety and reducing the impact on the environment were top priorities when designing the project. These future facilities will also lead to major savings of water and energy consumption and reduce effluents. The groundwork of the Comurhex II project has taken 150,000 hours of engineering over the past three years. Four hundred people will work on the site which will be launched in summer 2007. First industrial production is scheduled for 2012, based on 15,000 metric tons of uranium per year. This figure may be increased to 21,000 tons to meet market requirements

2014-01-01

The group posted a net loss in the first half of the year. This is the consequence of losses recorded in renewable operations, additional project-related provisions, asset write-downs and a nuclear market environment that has still deteriorated. Areva's backlog has strengthened thanks to the signing of the agreement through 2020 with EDF for used fuel treatment and MOX fuel production. Though it has a short-term adverse impact on the group's results, it provides these operations with long-term visibility and strengthens our strategic partnership with EDF. Despite a decline in revenue that was greater than anticipated, the group achieved positive free operating cash flow, an increase compared with the first half of 2013. The success of Areva's recovery actions partially offset the downturn in activity. These actions will be reinforced in the second half of the year to adapt to market conditions. The group continues to restructure its operations in renewable energies by entering into partnerships in promising markets, such as offshore wind and energy storage, and by discontinuing loss-making operations, such as concentrated solar power. 2014 Half-year results: - Backlog: euro 44.9 bn (euro +3.5 bn vs. 12/31/2013 thanks to the treatment-recycling agreement with EDF); - Negative net income attributable to equity owners of the parent (euro -694 m): Losses in discontinued renewable activities (euro -373 m), One-off impact of treatment-recycling agreement with EDF (euro -95 m), Provisions and assets impairment: - Positive free operating cash flow despite lower activity level: Revenue: euro 3.889 bn (-12.4% LFL), EBITDA: euro 256 m (euro -231 m vs. H1 2013), Free operating cash flow: euro 98 m (euro +256 m vs. H1 2013); - Strengthened recovery actions in an unfavorable economic environment: 2015 cost reduction objective secured and raised to euro 1.2 bn by 2016, Capital expenditure reduced over 2014-16; - Revised financial outlook

This brochure presents the GEN III+ EPR reactor designed by the Areva and Siemens consortium. The EPR reactor is a direct descendent of the well-proven N4 and KONVOI reactors, the most modern reactors in France and Germany. The EPR was designed by teams from KWU/Siemens and Framatome, EDF in France and the major German utilities, working in collaboration with both French and German safety authorities. The EPR integrates the results of decades of R and D programs, in particular those performed by the CEA (French Atomic Energy Commission) and the Karlsruhe Research Center in Germany. The EPR benefits from the experience of several thousand reactor-years of operation of pressurized water reactor technology. This experience has put 87 AREVA PWRs online throughout the world. Innovative Features: - An outer shell covering the reactor building, the spent fuel building and two of the four safeguard buildings provides protection against large commercial or military aircraft crash. - A heavy neutron reflector that surrounds the reactor core lowers uranium consumption. - An axial economizer inside the steam generator allows a high level of steam pressure and therefore high plant efficiency. - A core catcher allows passive collection and retention of the molten core should the reactor vessel fail in the highly unlikely event of a core melt. - A digital technology and a fully computerized control room with an operator friendly man-machine interface improve the reactor protection system.

The first half was an extremely active one for the consolidation of Areva's base of operations and for the deployment of the strategic road-map, where numerous milestones have been achieved. Areva's backlog and revenue are rising, while operating profitability continues to improve notably thanks to the group performance plans. On June 15, Areva presented its action plan for the creation of NEW CO, which detailed the achievements necessary to the complete and effective transformation of Areva. In particular, they include the plan to sell AREVA NP's operations, which met a new milestone with the signing of a memorandum of understanding with EDF, confirming the sale price and the schedule for closing by the end of 2017. Added to this memorandum of understanding was the completion of the sale of Canberra, the shut-down of the Bioenergy business and the upcoming sale of Adwen. The group intensified its discussions aimed at attracting strategic investors which could participate in the capital increase for NEW CO. Signs of interest have already been given. Meanwhile, liquidity requirements were secured for 2016. Armed with these actions and achievements, the group refines its objective for net cash flow from company operations, putting it at -1.5 billion euros for the current year, in the upper end of the range indicated at the beginning of the year

The first half of 2011 was marked by the accident at the Fukushima power plant following the unprecedented natural disasters that struck Japan. AREVA drew the first consequences from these events as early as June 2011 and recorded provisions and impairment in its half-year financial statements, related in particular to the expected short-term level of activity of some facilities. Close to 200 million euros in orders were canceled out of a total in backlog of more than 43 billion euros, which was down by a little more than 1 billion euros compared with the end of 2010. The longer term consequences of these events for AREVA are being assessed. They could concern all operations in the nuclear cycle and will be included in the strategic plan to be prepared by the end of the second half of the year. The fundamentals underpinning the development of the nuclear market are unchanged: strong growth in demand for electricity in the coming decades, diminished fossil resources, the search by many countries for energy independence, and the growing need to address climate issues. Through its efficient integrated business model, AREVA is present in every segment of the nuclear chain and is positioned in high-tech renewable energies with an offering that is perfectly suited to the requirements of the world's power companies. Decisions by governments on energy policy and by the safety authorities in different countries will influence market developments and the schedule for executing certain projects. Germany announced its decision to withdraw permanently from nuclear power and Switzerland intends to do the same, while Italy has opted not to restart its program. And yet the majority of countries have confirmed their decision to pursue nuclear power programs, present and future. In the first half, the group continued to draw down debt, achieving a net debt level of less than 3 billion euros at the end of June, thanks in particular to the conclusion of the proceedings with

Drexler, Andreas; Weiss, Steffen; Caris, Neil; Stiepani, Christoph

2015-01-01

Long-term integrity and high performance of major plant systems and components are of uppermost importance for the successful operation of any power plant. AREVA's experience gathered with water-steam cycle chemistry treatments in more than 40 years yields the conclusion: Accumulation of corrosion products in SGs may result in local overheating and enrichment of impurities up to critical levels. This can lead to several degradation phenomena of the structural materials of the SGs. Therefore, minimization of corrosion product generation and prevention of deposit accumulation is required. The objective of AREVA's asset management program is to support operators by minimizing corrosion damage and performance losses of water-steam cycle systems and components and thereby to maximize the availability and economic performance of the plant. Such asset management program is in principle a closed cycle process. It is based on control, corrective and preventive measures. The objective of control measure is deriving a widespread assessment of the corrosion status of the steam-water cycle which yields to weak points and identifying the best suited corrective and/or preventive measures. In the subsequent steps appropriate measures which improve the current status or counteract on identified issues are identified and applied. Corrective measures, likes mechanical and/or chemical cleaning are targeting the minimization of negative influence on plant performance caused by corrosion in the steam-water cycle. Complementary to corrective measures are preventive ones, like optimization of pH strategy and AREVA's FFA technology could by applied. They are focusing on the origin of corrosion product generation. AREVA is offering a toolbox for long-term best performance and reliable operation of NPPs. (author)

Lachaux, Manuel; Jugean, Anne-Sophie

2016-01-01

At September 30, 2016, AREVA had 32.160 billion euros in backlog, up 10.9% in relation to December 31, 2015 (28.990 billion euros). This represents close to eight years of revenue. The backlog at September 30 does not include contracts for uranium supply, conversion services and enrichment services signed with EDF and NNB in connection with the Hinkley Point C project. Those contracts will be included in backlog upon signature of the Notice to Proceed. The order intake for the first nine months of the year totaled 7.2 billion euros, compared with 1.2 billion euros for the same period last year. Over the first nine months of 2016, AREVA generated consolidated revenue of 2.810 billion euros, which was stable in relation to the same period in 2015 (+1.1% like for like). Foreign exchange had a negative impact of 5 million euros over the period. Revenue for the third quarter of 2016 totaled 880 million euros, a decrease of 6.0% (-5.5% like for like) in comparison to the third quarter of 2015. Foreign exchange had a negative impact of 5 million euros over the period. The operations of AREVA NP (excluding the OL3 project), Nuclear Measurements, and Propulsion and Research Reactors meet the criteria of IFRS 5 for classification as 'operations held for sale and discontinued operations' at September 30, 2016. The backlog of the operations held for sale was 13.265 billion euros at September 30, 2016, compared with 13.693 billion euros at the end of 2015. It does not include the contracts for two nuclear steam supply systems and for the supply of fuel and of the operational instrumentation and control system related to Hinkley Point C, which will be recorded upon signature of the Notice to Proceed. Revenue from the operations held for sale and discontinued operations totaled 2.595 billion euros at September 30, 2016, a decrease of 10.1% compared with the same period in 2015. This change is essentially due to: - A drop in the activity of AREVA NP, with lower volumes

The CATHARE code developed since 1979 by AREVA, CEA, EDF and IRSN is one of the major thermal-hydraulic system codes worldwide. In order to have at disposal realistic methodologies based on CATHARE for the whole transient and accident analysis in Chapter 15 of Safety Reports, a coupling with the code ARTEMIS was developed. ARTEMIS is the core code in AREVA's new reactor simulator system ARCADIA, using COBRA-FLX to model the thermal-hydraulics in the core. The Fully Coupled Methodology was adapted to the CATHARE-ARTEMIS coupling to perform Main Steam Line Break studies. This methodology, originally applied to the MANTA-SMART-FLICA coupling, is dedicated to Main Steam Line Break transients at zero power. The aim of this paper is to present the coupling between CATHARE and ARTEMIS and the application of the Fully Coupled Methodology in a different code environment. (authors)

Canat, J. N.; Mollard, P.; Gentet, G.; Uyeda, G.

2008-01-01

The first goal of the fuel designer is to closely address the customers' expectations, with the aim of providing them in the shortest possible time a flawless product fully addressing their needs. However, the designer knows from experience that designing a new fuel assembly is a task which always lasts a long time. Depending on the extent and innovative dimension of the performed changes, development and qualification of new products have lasted from a few years to as much as roughly 15 years. Experience feedback proves that developing and qualifying a cladding material is the longest-term process, requiring the determination of its behavior laws under irradiation and also under accident conditions. Regarding fuel assembly structure, new development generally requires the irradiation of Lead Test Assemblies during a period of time representative of the fuel operating conditions. This explains the critical importance of high powered, top quality modeling to adequately support the fuel assembly design development and the behavior assessment. Advanced calculation codes and methods, improved modeling tools and test facilities, are key contributors to reinforced reliability, robustness, thermal hydraulic performance and maneuverability of nuclear fuel under ever more demanding operational conditions. Sophisticated, high powered modeling tools and representative test capacities are cutting the time necessary for AREVA to develop a new product, license it and load it in the core of a reactor. This trend towards greater modeling capability has been backed up by the upgrading of computing means over the last few years, allowing the consideration of a large number of factors and a higher accuracy in the representation of the modeled phenomena. This article details how predictive tools currently play a more and more important role in the design developments engaged by AREVA. They have led to a more physical approach to finding technical solutions and allowed their analytical

2016-01-01

This document is Areva Namibia's stakeholder report for 2015. After some turbulent years, the company has now settled into the routine of care and maintenance and expect it to continue until the over-supply of uranium on the world market is depleted and the market conditions improve sustainably. Until then the Care and Maintenance team will continue protecting the mine's infrastructure so that it can be commissioned without delay as soon as the economic conditions become more favourable. The company also maintains its focus on process development and optimisation, on safety, occupational health and protection of the environment. The care and maintenance phase is giving an opportunity to thoroughly research the alkaline heap leach process and make improvements to the uranium recovery methods. The third phase of metallurgical test work will explore some new options to further reduce the cost of production and enhance the economic viability of Trekkopje mine. Preliminary bench testing carried out in mid-2015 at the Process Development Laboratory in France delivered promising results. The on-site testing program started in October 2015 and will continue into 2016. Areva Namibia has been very active in the community. Thanks to the desalination plant NamWater has been able to meet the water demand of the other uranium mines when pumping from the Omaruru Delta (Omdel) aquifer had to be reduced. Negotiations about the sale of the plant are at an advanced stage. The company is supporting social projects in the areas of economic development, education, culture and sport in its neighbouring communities of Arandis and Swakopmund and in the wider Erongo region. This report presents some of the highlights of this active engagement with stakeholders at the local, regional and national level.

2013-01-01

The availability of reliable tools and associated methodology able to accurately predict the LWR fuel behavior in all conditions is of great importance for safe and economic fuel usage. For that purpose, AREVA has developed its new global fuel rod performance code GALILEO along with its associated realistic thermal-mechanical analysis methodology. This realistic methodology is based on a Monte Carlo type random sampling of all relevant input variables. After having outlined the AREVA realistic methodology, this paper will be focused on the GALILEO code benchmarking process, on its extended experimental database and on the GALILEO model uncertainties assessment. The propagation of these model uncertainties through the AREVA realistic methodology is also presented. This GALILEO model uncertainties processing is of the utmost importance for accurate fuel design margin evaluation as illustrated on some application examples. With the submittal of Topical Report GALILEO to the U.S. NRC in 2013, GALILEO and its methodology are on the way to be industrially used in a wide range of irradiation conditions. (authors)

The Areva group reached a major milestone in 2013 in turning performance around by meeting a key objective of its Action 2016 plan: the return to breakeven of free operating cash flow. For the first time since 2005, cash generated by the Group's operations allowed it to fully fund strategic capital expenditures essential to the group's profitable growth. To achieve this result, Areva built on robust growth in nuclear operations, on contributions from its cost reduction plan and on strict management of capital spending. However, two projects launched in the previous decade (OL3 and a power plant modernization) and the Renewable Energies business impacted negatively the group's 2013 net income. On the Renewable Energies market, in a situation marked by a reduction of capital spending by customers, AREVA anticipated the consolidation required in the sector by implementing industrial partnerships such as the joint venture project with Gamesa, which aims to create a European champion in offshore wind. Similar initiatives were undertaken in solar energy and energy storage. The Group continues to implement the Action 2016 plan to pursue its recovery. While the economic environment remains uncertain and projects launched in the previous decade remain a burden, the Group forecasts further performance improvement and significant growth in cash flow generation by the end of the plan

Lommers, L.; Shahrokhi, F.; Southworth, F.; Mayer, J. III

2014-01-01

The AREVA Steam Cycle – High Temperature Gas-Cooled Reactor (SCHTGR) is a modular graphite-moderated gas-cooled reactor currently being developed to support a wide variety of applications including industrial process heat, high efficiency electricity generation, and cogeneration. It produces high temperature superheated steam which makes it a good match for many markets currently dependent on fossil fuels for process heat. Moreover, the intrinsic safety characteristics of the SC-HTGR make it uniquely qualified for collocation with large industrial process heat users which is necessary for serving these markets. The NGNP Industry Alliance has selected the AREVA SC-HTGR as the basis for future development work to support commercial HTGR deployment. This paper provides a concise description of the SC-HTGR concept, followed by a summary of recent development activities. Since this concept was introduced, ongoing design activities have focused primarily on confirming key system capabilities and the suitability for potential future markets. These evaluations continue to confirm the suitability of the SC-HTGR for a variety of potential applications that are currently dependent on fossil fuels. (author)

After the Coordinated Research Project (CRP) FUMEXII, participants asked for a new exercise within an IAEA CRP. This CRP started in December 2008 in Vienna with the first Research Coordination Meeting (RCM). The CRP is titled ''Improvement of Computer Codes Used for Fuel Behaviour Simulation FUMEX III''. The object of FUMEX III were the improvement of fuel rod performance codes for modeling high burnup phenomena in modern fuel. This includes transient behavior, as well as mechanical interaction between pellet and cladding and, in progression to the FUMEX II exercise, fission gas release during various conditions (steady state, load follow, transient). AREVA NP agreed on participating in this exercise under the IAEA research agreement no. 15369 and expressed interest in the modeling of pelletclad mechanical interactions as well as fission gas release under steady state and transient conditions. In this exercise AREVA NP used its new global fuel rod code GALILEO, which is still under development (formerly known under the project name COPERNIC 3). During a Consultants Meeting potential topics and a proposed selection of cases have been prepared, which were discussed during the 1st Research Coordination Meeting (RCM) in Vienna in December 2008. During the discussions a number of additional cases motivated by the participants have been identified. Finally, a case table has been agreed upon, which included several cases for the different topics. Most of the cases have been based on the International Fuel Performance Experiments (IFPE) database, but additional cases have been provided during the exercise (e.g., the AREVA idealized case

AREVA T and D wins de-icing contract in Quebec

2005-04-01

The ice storm that struck Quebec in the winter of 1998 left millions of people without electricity because the accumulation of ice caused the collapse of hundreds of kilometres of high-voltage transmission lines and thousands of transmission towers. In order to optimize the security of its power grid, Hydro-Quebec contracted AREVA T and D to construct and install HVDCice{sup TM}, a transmission line de-icing system based on high-voltage direct current (HVDC) technology. The system is intended to ensure maximum electrical efficiency and guarantee a secure electricity supply. The system will generate up to 7200A of direct current in the transmission lines. This will raise their temperature thereby allowing the ice to melt and fall off. The system will be implemented at the Levis substation, a major connection point for the transmission lines of the province. The system also acts as a Static Var Compensator (SVC) to improve the power quality of the transmission network. The SVC will stabilize the voltage on the 735 kV power grid, which can fluctuate depending on the amount of electricity being consumed. This is the world's first HVDC-based de-icing and power quality system. The contract awarded to AREVA's T and D division is estimated at 25 million Euros. 1 fig.

AREVA NP Liner Repair Strategy with Adhesive Technology

International Nuclear Information System (INIS)

Georg, Kraemer; Revoirard, Sebastien; McCann, James-E.

2012-09-01

AREVA has developed a repair method for sealing leakages in austenitic stainless steel liners, especially in nuclear power plants. This technology is either a repair, when applied after failures already occurred, or a prophylaxis, when applied before failures occurred. Leakages of stainless steel pool liners can be classified into basically four mechanisms: Mechanical impact, mechanical stress, weld failures and corrosion. Damage from mechanical impact like dropping tools or equipment can be usually recognized and localized immediately. In such situations no extensive leak detection needs to be performed. Contrary to the mechanical damage, it is more difficult to localize damages due to mechanical stress, such as load changes or thermal stress. Load changes occur when a stainless steel pool is repeatedly filled and drained, thermal stress occurs when a pool is exposed to temperature gradients. Those two preconditions are given in reactor cavities (RC). Mechanical stress usually promotes other pre-existing defects. According to the experience of AREVA the weld failures are not a common root cause for leakages, found after several years of operation. They are due to the standard testing procedure in which all weld seams are checked (with e.g. Penetrate Testing (PT) for example). If failures are detected, they are repaired during the commissioning. The main root cause for leakages found after several years of operation is corrosion. Corrosion failures themselves are mainly caused by stress corrosion cracking (SCC). SCC needs certain preconditions to initiate: Mechanical stress must exist; a corrosion initiating element (e.g. chlorine) above a limiting concentration is necessary as well as a heat affected zone (HAZ). In the HAZ, which is exists near weld seams, the microstructure of the stainless steel has changed. This leads to a higher susceptibility to SCC. Those preconditions for SCC cannot be found at the front side of the liner (water side), because the water

Estimates of process and secondary wastes produced by a recycling plant built in the U.S., which is composed of a used nuclear fuel (UNF) reprocessing facility and a mixed oxide (MOX) fuel fabrication facility, are performed as part of a U.S. Department of Energy (DOE) sponsored study [1]. In this study, a set of common inputs, assumptions, and constraints were identified to allow for comparison of these wastes between different industrial teams. AREVA produced a model of a reprocessing facility, an associated fuel fabrication facility, and waste treatment facilities to develop the results for this study. These facilities were divided into a number of discrete functional areas for which inlet and outlet flow streams were clearly identified to allow for an accurate determination of the radionuclide balance throughout the facility and the waste streams. AREVA relied primarily on its decades of experience and feedback from its La Hague (reprocessing) and MELOX (MOX fuel fabrication) commercial operating facilities in France to support this assessment. However, to perform these estimates for a U.S. facility with different regulatory requirements and to take advantage of some technological advancements, such as in the potential treatment of off-gases, some deviations from this experience were necessary. A summary of AREVA's approach and results for the recycling of 800 metric tonnes of initial heavy metal (MTIHM) of LWR UNF per year into MOX fuel under the assumptions and constraints identified for this DOE study are presented.

Some of them are now commonly used for maintenance operations at the AREVA NC (Nuclear Cycle) La Hague reprocessing plant. Since the first maintenance operation in 2005, several other successful interventions have been realized using the industrial MA23/RX170 tele-manipulation system. Moreover, since 2010, the through-the-wall tele-robot named MT200 TAO based on the slave arm of the MSM MT200 (La Calhene TM ), has been evaluated in an active production cell at the AREVA NC La Hague fuel recycling plant. Although these evaluations are ongoing, the positive results obtained have led to an update and industrialization program. All these developments are based on the same generic control platform, called TAO2000 V2. TAO2000 V2 is the second release of the CEA LIST core software platform dedicated to computer aided force-feedback tele-operation (TAO is the French acronym for computer aided tele-operation). This paper presents all these developments resulting from the joint research program CEA LIST/AREVA. The TAO2000 V2 controller is first detailed, and then two maintenance operations using the industrial robot RX170 are presented: the removal of the nuclear fuel dissolver wheel rollers and the cleanup of the dissolver wheel inter-bucket spaces. Finally, the new MT200 TAO system and its evaluations at the AREVA NC La Hague facilities are discussed. (authors)

The AREVA's waste management strategy

International Nuclear Information System (INIS)

Poncet, Ph.

2011-01-01

In accordance with its policy of sustainable development and continuous progress, AREVA is permanently seeking to reduce the impact of the management of its waste, of whatever type, and its radioactive waste in particular. This goal is taken into consideration very early in industrial projects and concerns all the phases in the life of the installations and all the activities of the Group. The resulting actions aim to guarantee that an exhaustive inventory is made of the radioactive materials and waste, to optimise how they are characterised, to ensure their traceability and to determine the best management methods. Past and future progress relies primarily on the effectiveness of zoning (in particular the concept of radiological cleanness), how work is organized, the account taken of operating experience feedback, the search for recycling solutions or appropriate removal routes, optimisation of waste storage and, whenever possible, online processing, plus of course the professionalism of all those involved. A participatory approach by the Group will enable the focus areas and required actions to be defined: networks and multidisciplinary working groups, whenever possible in association with other stake-holders or partners from the nuclear industry.

Full text: Introduction: This study has been established in order to evaluate the mortality of nuclear workers employed at the French company specialized in nuclear fuel cycle (AREVA NC ex COGEMA) and exposed to low level of ionizing radiation. The follow-up of the cohort has been extended recently. We present here a new analysis of the mortality based on an extended follow-up of the cohort by 10 years. Methods: Administrative data, vital status and causes of death were reconstructed for each worker. Standardized Mortality ratios (SMR) were computed using national mortality rates as external reference adjusted for sex, age and calendar year. Trend tests were computed to assess the association between different causes of death and radiation exposure considering adjustment on socioeconomic status (SES). Results: 93% of the 9,285 workers were male workers. They were followed for an average of 22 years, with a total number of person-years of 206,603. The % of subjects lost to follow-up was less than 1%. 1,052 deaths occurred during the total follow-up period. 98% of the causes of death were identified. Mean age at end of follow-up was 56 years. As excepted, a strong deficit was observed for all causes of death (SMR=0.64; 90% confidence interval CI : 0.60-0.67) and all cancer mortality (SMR=0.77; 90% confidence interval CI : 0.71-0.83). No significant excess was found for any of the considered causes of death. The all-causes and all cancers SMRs increased significantly with cumulative dose, but after adjusting on SES, these positive trends were no longer statistically significant. Among the 30 causes of deaths studied, significant trends were observed for colon, liver cancer and for non-cancer respiratory diseases. Conclusion: AREVA NC workers exposed to ionizing radiation have a lower mortality than the French national population, partly due to the Healthy Worker Effect. It is important to adjust on SES in the dose-effect relationship analysis. Although follow-up has

Regulatory requirements for the Instrumentation and Control (IC) for Nuclear Power Plants have become significantly more stringent during the last 10 years in the areas of software development and qualification, traceability, diversity, or seismic requirements for instance, and with the introduction of new standards (such as the IEC 62566, or the IEC 62003). Based on a large and comprehensive experience gained from projects in several regulatory environments and different plant types (including non-OEM plants), AREVA has developed and adapted its processes and products to provide state-of-the-art IC solutions in full compliance with the regulatory demands and requirements in terms of robustness (independence, defense-in-depth, diversity and cyber-security). In this paper we present the safety IC platforms developed by AREVA. These platforms include TELEPERM XS as the computerized safety IC platform for class 1 system implementation, the Qualified Display System (QDS) for safety classified screen-based interface, and UNICORN as fully diverse analog safety IC platform for backup systems

After 40 years of service, it belongs to the safest 25 % of all light-water reactors in the western hemisphere thanks to continuous modernisation. In doing so, Borssele is setting standards for maintenance and upgrades. In view of the continuation of operation until 2034, further comprehensive modernisation projects are planned. The plant operator, the Dutch N.V. Elektriciteitsproduktiemaatschappij (EPZ), decided to tackle this challenge with the support of its long-standing partner AREVA. Another milestone is coming up soon: The safety I and C shall gradually be changed to digital technology in the next years. Apart from close cooperation in plant technology, EPZ and AREVA also cooperate in fuel supply, as well as in the area of service and maintenance work.

Mitigation of severe accidents in AREVA's Gen 3+ nuclear power plants

Energy Technology Data Exchange (ETDEWEB)

Fischer, M., E-mail: manfred.fischer@areva.com; Henning, A.; Surmann, R.

2014-04-01

The current AREVA Gen 3+ PWR designs (EPR™ and ATMEA1) are based on the proven defense-in-depth safety concepts inherited from their predecessors, the French “N4” and the German “Konvoi” reactors. Complemented by specific enhancements, including higher redundancy and diversity as well as the use of passive systems, this leads to very low values of the core damage frequency (CDF). Notwithstanding this very low probability, dedicated design measures have been implemented to improve the response of the plant in case of a postulated severe accident (SA) with core melting. This way not only the frequency of large-early-releases (LERF) but also the related radiological consequences are drastically reduced. Situations that potentially lead to high loads that can challenge the short-term integrity of the containment, like RPV melt-through under high pressure, energetic hydrogen/steam explosions, as well as long-term containment failure caused by internal over-pressure are avoided by a combination of preventive measures and dedicated systems. At the example of the EPR{sup TM}, the paper gives an overview of the severe accident mitigation strategy and the related measures and systems of AREVAs current Gen 3+ reactors, with special focus on the function of the core melt stabilization system.

2004-01-01

The French industrial group Areva, that gathers Cogema and Framatome-ANP, has entered into a partnership with the British nuclear consortium Urenco for creating ETC (enrichment technology company) in order to replace its uranium enrichment facility (Georges-Besse-I) that is planned to close in 2012 by a new one (George-Besse-II) that will enter into service as early as 2007. The new facility will be based on the centrifugation technique developed by Urenco, this technique will cut the consumption of electricity by 3 in comparison with the gaseous diffusion technique used in the Georges-Besse-I facility. The other asset of the centrifugation technique is that the facility can grow with the number of centrifuges that are set. In 2007 only 7% of the total number of centrifuges will be installed, which will sufficient to satisfy the demand for enriched uranium. The full size of the facility will be reached in 2016 through gradual steps of 10% more centrifuges set every year. (A.C.)

This complementary safety assessment analyses the robustness of the Areva part of the Tricastin nuclear site to extreme situations such as those that led to the Fukushima accident. This study includes the following facilities: Areva NC Pierrelatte, EURODIF production, Comurhex Pierrelatte, Georges Besse II plant and Socatri. Robustness is the ability for the plant to withstand events beyond which the plant was designed. Robustness is linked to safety margins but also to the situations leading to a sudden deterioration of the accidental sequence. Moreover, safety is not only a matter of design or engineered systems but also a matter of organizing: task organization (including subcontracting) as well as the setting of emergency plans or the inventory of nuclear materials are taken into consideration in this assessment. This report is divided into 10 main chapters: 1) the feedback experience of the Fukushima accident; 2) description of the site and its surroundings; 3) featuring of the site's activities and installations; 4) accidental sequences; 5) protection from earthquakes; 6) protection from floods; 7) protection from other extreme natural disasters; 8) the loss of electrical power and of the heat sink; 9) the management of severe accidents; and 10) subcontracting policy. This analysis has identified 5 main measures to be taken to limit the risks linked to natural disasters: -) continuing the program for replacing the current conversion plant and the enrichment plant; -) renewing the storage of hydrofluoric acid at the de-fluorination workshop; -) assessing the seismic behaviour of some parts of the de-fluorination workshop and of the fluorine fabrication workshop; -) improving the availability of warning and information means in case of emergency; and -) improving the means to mitigate accidental gaseous releases.

As a leading provider of technological solutions for nuclear power generation and electricity transmission, the AREVA group has the unique capability of offering a fully integrated fuel supply, when requested by its customers. At the core of the AREVA group, COGEMA Front End Division is an essential part of the overall fuel supply chain. Composed of three Business Units and gathering several subsidiaries and joint 'ventures, this division enjoys several leading positions as shown by its market shares and historical production records. Current Uranium market evolutions put the natural uranium supply under focus. The uranium conversion segment also recently revealed some concerning evolutions. And no doubt, the market pressure will soon be directed also at the enrichment segment. Looking towards the long term, AREVA strongly believes that a nuclear power renewal is needed, especially to help limiting green house effect gas release. Therefore, to address future supplies needed to fuel the existing fleet of nuclear power plants, but also new ones, the AREVA group is planning very significant investments to build new facilities in all the three front-end market segments. As far as uranium mining is concerned, these new mines will be based upon uranium reserves of outstanding quality. As for uranium conversion and enrichment, two large projects will be based on the most advanced technologies. This paper is aimed at recalling COGEMA Front End Division experience, the current status of its plants and operating entities and will provide a detailed overview of its major projects. (authors)

Environmental assessment, continual improvement and adaptive management within the AREVA sustainable development framework

Rosaasen, A.; Frostad, S.

2006-01-01

COGEMA Resources Inc. (which is part of the AREVA Group) is a Canadian company with its head office in Saskatoon, Saskatchewan. It owns and operates mining and milling facilities in northern Saskatchewan, which produce uranium concentrate. The McClean Lake Operation commenced production in 1999 and its environmental management system represents an integrated approach to environmental assessment, continual improvement and adaptive management based on operational results. In Canada, sustainable development is promoted through the application of the Canadian Environmental Assessment Act (CEAA). Environmental Assessment (EA) is a planning tool, which incorporates environmental considerations before irrevocable decisions are taken. The basic tenet of the Act is the determination of whether the potential environmental effects of a project are adverse, significant and likely, taking into consideration mitigation measures. Thus, project planning and design entails an iterative process that incorporates mitigation measures to minimize potentially significant adverse effects. As part of the EA process conservative approaches are taken to predict potential effects. Several important elements are generated through the EA process including: a set of environmental effects predictions, a compliance and environmental effects monitoring program, a follow-up program to address uncertainties in the prediction of environmental effects, and the identification of contingency measures that could be implemented should non-conservative assumptions be identified in the original assessment framework. The challenge is to integrate each of these elements into the environmental management framework of the operating facility and develop an iterative mechanism to evaluate operational performance relative to what was originally predicted. In Saskatchewan, a requirement of operational licenses is the periodic evaluation of the 'Status of the Environment' surrounding operational facilities. These

AREVA NP has developed a next-generation coupled neutronics/thermal-hydraulics code system, ARCADIA R , to fulfil customer's current demands and even anticipate their future demands in terms of accuracy and performance. The new code system will be implemented world-wide and will replace several code systems currently used in various global regions. An extensive phase of verification and validation of the new code system is currently in progress. One of the principal components of this new system is the core simulator, ARTEMIS. Besides the stand-alone tests on the individual computational modules, integrated tests on the overall code are being performed in order to check for non-regression as well as for verification of the code. Several benchmark problems have been successfully calculated. Full-core depletion cycles of different plant types from AREVA's French, American and German regions (e.g. N4 and KONVOI types) have been performed with ARTEMIS (using APOLLO2-A cross sections) and compared directly with current production codes, e.g. with SCIENCE and CASCADE-3D, and additionally with measurements.

In-air tritium measurements were conducted around the AREVA NC La Hague reprocessing plant, as well as on other sites that are not impacted by the nuclear industry in northwest of France. The results indicate that the dominant tritium form around the AREVA site is HT (86%). HT and HTO levels are lower than 5 and 1 Bq. m -3 for hourly samples taken in the plume. No tritiated organic molecules (TOM) were detected. 26 measurement campaigns were performed and links were established between near-field 85 Kr, HT and HTO activities. Environmental measurements are in line with those taken at the discharge stack, and tend to demonstrate that there are no rapid changes in the tritium forms released. Out of the influence of any nuclear activities, the levels measured were below 13 mBq.m -3 for HT and 5 mBq.m -3 for HTO (<0.5 Bq. L -1 ). HTO level in air seems to be influenced by HTO activities in surrounding seawater. Copyright © 2017 Elsevier Ltd. All rights reserved.

2008-01-01

In the AREVA's HTR development program, the reactor plant is composed of a prismatic core containing graphite cylindrical fuel elements, called compacts, where TRISO particles are dispersed. Starting from its past compacting process, the latter being revamped through the use of state of the art equipments, CERCA, 100% AREVA NP's subsidiary, was able to recover the quality of past compacts production. The recovered compacting process is composed of the following manufacturing steps: graphite matrix granulation, mix between the obtained granulates and particles, compacting and calcining at low pressure and temperature. To adapt this past process to new manufacturing equipments, non destructive examination tests were carried out to assess the compact quality, the latter being assessed via in house developed equipments and methods at each step of the design of experiments. As for the manufacturing process, past quality control methods were revamped to measure compact dimensional features (diameter, perpendicularity and cone effect), visual aspect, SiC layer failure fraction (via anodic disintegration and burn leach test) and homogeneity via 2D radiography coupled to ceramography. Although meeting quality requirements, 2D radiography method could not provide a quantified specification for compact homogeneity characterization. This limitation yielded the replacement of this past technique by a method based on X-Ray tomography. Development was conducted on this new technique to enable the definition of a criterion to quantify compact homogeneity, as well as to provide information about the distances in between particles. This study also included a comparison between simulated and real compacts to evaluate the accuracy of the technique as well as the influence of particle packing fraction on compact homogeneity. The developed quality control methods and equipments guided the choices of manufacturing parameters adjustments at the development stage and are now applied for

Control and maintenance of the Superphenix knowledge and its specific sodium skills through an innovative partnership between EDF and AREVA

International Nuclear Information System (INIS)

Calais, Thomas; Rauber, Jean-Claude

2016-01-01

Superphenix is a 1200 MWe sodium cooled Fast Breeder Reactor (FBR) located in Creys-Malville (France). Its grid coupling occurred in 1986 and its final shutdown pronounced through a decree, 12 years later, in 1998. This Superphenix final shutdown decision marked a new stage in the life of the nuclear plant. Decommissioning activities were highly challenging due to the following: - Non recurrent and first-of-a-kind (FOAK) characteristics; - Environment constraints: radiation level, high temperatures, presence of argon, sodium, NaK, soda, hydrogen, etc.; - Complexity of the primary vessel internal structures; - Numerous interfaces to manage; - Numerous technical uncertainties due to the difficulty in anticipating the effective state of components (sodium and aerosols retentions, tritium concentration, NaK alteration, etc.). At the end of 1998, exchanges took place between EDF as 'Superphenix nuclear operator' and AREVA as 'Superphenix Nuclear Steam System Supply (NSSS) designer' in order to find the best way to meet the new challenge of decommissioning Superphenix. A key ingredient to achieving success was to ensure that existing local and specific sodium skills were controlled and maintained. AREVA was selected by EDF as its industrial partner for the sodium activities on this project being entrusted with the following missions: - Maintaining and adapting a strong EDF / AREVA partnership within the project duration; - Supplying support as the 'NSSS Designer'; - Rolling-out multidisciplinary skills from the design to the on-site operations; - Relying on its best technical experts to solve each technical challenge; - Developing and adapting durable specific skills of its technical team (sodium, mechanical, process, I and C, statutory, etc.) following each stage of the decommissioning. This EDF/AREVA partnership on the sodium activities has taken different forms according to the different stages of the project. From 1998 to 2005, AREVA was

Repair methods with conventional welding technique are not promising as a preventative measure mostly due to cost and time issues. With the provided repair method, the AREVA adhesive technology, it is possible to stop existing leaks and work as a prophylactic measure against future penetration from the concrete side of the pool. This technique can cover the failure mechanisms from weld failures over corrosion to mechanical stresses. Another advantage of the adhesive technology is the possibility of using remote-controlled underwater repair methods which are particularly beneficial in the repair of leaks in spent fuel pools. Extensive laboratory testing and longstanding successful experience in nuclear power plants have proved the suitability of the adhesive technology as active and proactive methods to minimize leakages in pools.

Status of safety at Areva group facilities. 2006 annual report

International Nuclear Information System (INIS)

2006-01-01

This report presents a snapshot of nuclear safety and radiation protection conditions in the AREVA group's nuclear installations in France and abroad, as well as of radiation protection aspects in service activities, as identified over the course of the annual inspections and analyses program carried out by the General Inspectorate in 2006. This report is presented to the AREVA Supervisory Board, communicated to the labor representation bodies concerned, and made public. In light of the inspections, appraisals and coordination missions it has performed, the General Inspectorate considers that the nuclear safety level of the AREVA group's nuclear installations is satisfactory. It particularly noted positive changes on numerous sites and efforts in the field of continuous improvement that have helped to strengthen nuclear safety. This has been possible through the full involvement of management teams, an improvement effort initiated by upper management, actions to increase personnel awareness of nuclear safety culture, and supervisors' heightened presence around operators. However, the occurrence of certain events in facilities has led us to question the nuclear safety repercussions that the changes to activities or organization on some sites have had. In these times of change, drifts in nuclear safety culture have been identified. The General Inspectorate considers that a preliminary analysis of the human and organizational factors of these changes, sized to match the impact the change has on nuclear safety, should be made to ensure that a guaranteed level of nuclear safety is maintained (allowance for changes to references, availability of the necessary skills, resources of the operating and support structures, etc.). Preparations should also be made to monitor the changes and spot any telltale signs of drift in the application phase. Managers should be extra vigilant and the occurrence of any drift should be systematically dealt with ahead of implementing

In the framework of the French V/HTR fuel development and qualification program, the Commissariat a l'Energie Atomique (CEA) and AREVA through its program called ANTARES (Areva New Technology for Advanced Reactor Energy Supply) conduct R and D projects covering the mastering of UO 2 coated particle and fuel compact fabrication technology. To fulfill this task, a review of past knowledge, of existing technologies and a preliminary laboratory scale work program have been conducted with the aim of retrieving the know-how on HTR coated particle and compact manufacture: - The different stages of UO 2 kernel fabrication GSP Sol-Gel process have been reviewed, reproduced and improved; - The experimental conditions for the chemical vapour deposition (CVD) of coatings have been defined on dummy kernels and development of innovative characterization methods has been carried out; - Former CERCA compacting process has been reviewed and updated. In parallel, an experimental manufacturing line for coated particles, named GAIA, and a compacting line based on former CERCA compacting experience have been designed, constructed and are in operation since early 2005 at CEA Cadarache and CERCA Romans, respectively. These two facilities constitute the CAPRI line (CEA and AREVA PRoduction Integrated line). The major objectives of the CAPRI line are: - to recover and validate past knowledge; - to permit the optimisation of reference fabrication processes for kernels and coatings and the investigation of alternative and innovative fuel design (UCO kernel, ZrC coating); - to test alternative compact process options; - to fabricate and characterize fuel required for irradiation and qualification purpose; - to specify needs for the fabrication of representative V/HTR TRISO fuel meeting industrial standards. This paper presents the progress status of the R and D conducted on V/HTR fuel particle and compact manufacture by mid 2005. (authors)

Areva fatigue concept. Fast fatigue evaluation, a new method for fatigue analysis

International Nuclear Information System (INIS)

Heinz, Benedikt; Bergholz, Steffen; Rudolph, Juergen

2011-01-01

Within the discussions on the long term operation (LTO) of nuclear power plants the ageing management is on the focus of that analysis. The knowledge of the operational thermal cyclic load data on components of the power plants and their evaluation in the fatigue analysis is a central concern. The changes in fatigue requirements (e.g. the consideration of environmentally assisted fatigue - EAF) recently discussed and LTO efforts are a strong motivation for the identification of margins in the existing fatigue analysis approaches. These margins should be considered within new approaches in order to obtain realistic (or more accurate) analysis results. Of course, these new analysis approaches have to be manageable and efficient. The Areva Fatigue Concept (AFC) offers the comprehensive conceptual basis for the consideration of fatigue on different levels and depths. The combination of data logging and automated fatigue evaluation are important modules of the AFC. Besides the established simplified stress based fatigue estimation Areva develops a further automated fatigue analysis method called Fast Fatigue Evaluation (FFE). This method comprises highly automated stress analyses at the fatigue relevant locations of the component. Hence, a component specific course of stress as a function of time is determined based on FAMOS or similar temperature measurement systems. The subsequent application of the rain flow cycle counting algorithm allows for the determination of the usage factor following the rules of the design code requirements. The new FFE approach constitutes a cycle counting method based on the real stresses in the component, and determined as result a rule-conformity cumulative usage factor. (orig.)

AREVA. Operating and financial results for the first half of 2011

2011-01-01

The first half of 2011 was marked by the accident at the Fukushima power plant following the unprecedented natural disasters that struck Japan. AREVA drew the first consequences from these events as early as June 2011 and recorded provisions and impairment in its half-year financial statements, related in particular to the expected short-term level of activity of some facilities. Close to 200 million euros in orders were canceled out of a total in backlog of more than 43 billion euros, which was down by a little more than 1 billion euros compared with the end of 2010. The longer term consequences of these events for AREVA are being assessed. They could concern all operations in the nuclear cycle and will be included in the strategic plan to be prepared by the end of the second half of the year. The fundamentals underpinning the development of the nuclear market are unchanged: strong growth in demand for electricity in the coming decades, diminished fossil resources, the search by many countries for energy independence, and the growing need to address climate issues. Through its efficient integrated business model, AREVA is present in every segment of the nuclear chain and is positioned in high-tech renewable energies with an offering that is perfectly suited to the requirements of the world's power companies. Decisions by governments on energy policy and by the safety authorities in different countries will influence market developments and the schedule for executing certain projects. Germany announced its decision to withdraw permanently from nuclear power and Switzerland intends to do the same, while Italy has opted not to restart its program. And yet the majority of countries have confirmed their decision to pursue nuclear power programs, present and future. In the first half, the group continued to draw down debt, achieving a net debt level of less than 3 billion euros at the end of June, thanks in particular to the conclusion of the proceedings with Siemens

Chapoutier, Nicolas; Mollier, François; Nolin, Guillaume; Culioli, Matthieu; Mace, Jean-Reynald

2017-09-01

In the context of the rising of Monte Carlo transport calculations for any kind of application, AREVA recently improved its suite of engineering tools in order to produce efficient Monte Carlo workflow. Monte Carlo codes, such as MCNP or TRIPOLI, are recognized as reference codes to deal with a large range of radiation transport problems. However the inherent drawbacks of theses codes - laboring input file creation and long computation time - contrast with the maturity of the treatment of the physical phenomena. The goals of the recent AREVA developments were to reach similar efficiency as other mature engineering sciences such as finite elements analyses (e.g. structural or fluid dynamics). Among the main objectives, the creation of a graphical user interface offering CAD tools for geometry creation and other graphical features dedicated to the radiation field (source definition, tally definition) has been reached. The computations times are drastically reduced compared to few years ago thanks to the use of massive parallel runs, and above all, the implementation of hybrid variance reduction technics. From now engineering teams are capable to deliver much more prompt support to any nuclear projects dealing with reactors or fuel cycle facilities from conceptual phase to decommissioning.

During the hearing, the chairwoman of AREVA's board of management answered questions about some events which occurred in Cadarache (plutonium retention in a plutonium workshop), and about the international strategy of AREVA. First, she outlines that this strategy is based on 'zero CO 2 ' objective. Thus, she evokes the various nuclear reactors her company proposes all over the world, the rather strong position in the biomass sector (transformation of vegetal wastes in electricity) in important countries, the activities in fuel cell technology and in wind energy production. She gives an assessment of the obtained security level in terms of number of accidents per million of working hours. She comments the reactions after the Cadarache incident. Then, she answers questions about these different issues

After a description of the uranium exploitation context (involved companies, production) in Arlit, Niger, by Cogema-Areva subsidiary companies, this report describes the context of controls performed by the CRIIRAD laboratory. Then, it reports and comments the contamination of underground so-called drinkable waters (contamination risks, Cogema statement, detection of a rather high concentration of alpha emitters, measurements performed in 2004 and 2005). The authors notice that water contamination is known by Cogema. Then, the report analyzes the issue of contaminated scrap metal dispersal, comments and criticizes the attitude of Cogema with respect to the associated risks. It comments the uranate transport accident which occurred in February 2004, the subsequent contamination, actions performed by Cogema, the associated health risks, and the statements made by Areva and Cogema. It also comments and analyzes the risks related to radioactive radon dusts inhalation around different sites and because of some technical practices, and Cogema statements about this issue. In conclusion, the authors outline the need of reinforced controls and of an epidemiological study, and outlines how Areva propagates wrong ideas

Qualification of a laser cutting process for nuclear dismantling operations AREVA NC BU Valorisation - CEA/DPAD - IRSN/DSU/SERAC

International Nuclear Information System (INIS)

2008-01-01

A major decommissioning project is under way on the Marcoule French Atomic Site (CEA) at the UP1 reprocessing plant where AREVA plays the role of prime contractor. Due to severe radiological levels on certain cells, these require remote operations. The cutting tools commonly used today are mainly mechanical such as grinders, saws and hydraulic shears. Nowadays, the feed-back shows that the implementation of these mechanical techniques: *?Is the main factor of mechanical failures of the remote arms. *?Requires a lot of spare parts (saw blades, discs...) The future cutting operations to be done in the UP1 reprocessing plant needs to be more industrial and productive. That is why CEA and AREVA NC are evaluating a new cutting process based on a laser set up on a remote arm. The laser cutting is already widely used in none nuclear environment and the goal is to evaluate if this thermal process may be used in nuclear installations with existing remote control arms.

The combination of AREVA's BWR FDIC-PEZOG tools allows the calculation of the total liftoff as a measure of fuel performance and a risk indicator for fuel reliability. The AREVA BWR FDIC tool is a crud modeling tool. The PEZOG tool models the platinum-enhanced zirconium oxide growth of fuel cladding when exposed to platinum during operation. Continuous effort to improve these tools used for the total liftoff calculations is illustrated by the benchmarking of the tools after the application of On-Line NobleChem TM at TVA Browns Ferry Unit 3 during Cycle 15. A set of runs using the modified FDIC-PEZOG model and actual plant water chemistry for Cycle 15 and partial data for Cycle 16 were performed. The updated results' deposit thickness and deposit composition predictions for EOC15 were compared to the measured data from EOC15 and are presented in this paper. The updated predicted deposit thickness matched the actual, measured value exactly. Predicted deposit composition near the fuel rod boundary, nearer to the bulk reactor water, and as an averaged deposit, as presented in the paper, compared extremely well with the measured data at EOC15. The updated AREVA methodology resulted in lower fuel oxide thickness predictions over the life of the fuel as compared to the initial evaluations for BFE3 by incorporating more recent experimental data on the thermal conductivity of zirconia; unnecessary conservatism in the prediction of the fuel oxide thickness over the life of the fuel was removed in the improved model.

After having recalled the context of the Messmer plan of 1974 according to which the roles of the different actors of the nuclear sector were clearly distributed, this article describes and comments the evolution of this context, notably after the N4 threshold has been reached: the French industry has lost many experts (they are retired), the concurrence has evolved as well as relationships between clients and providers. The article outlines that a new balance between the main actors is now needed. It comments the case of the EPR, the emergence of new PWR concepts, the different roles EDF, AREVA, GDF-Suez or Total may have depending on the project (they can be client, investor, or operator). Principles for a new strategy and operation for this sector and its actors are formulated

Prevention of fatigue damage of components is an important topic with respect to safety and availability of a nuclear power plant. The issue of fatigue monitoring should be of primary interest throughout service life. Based on the changing general framework, i.e. planning of new plants with a projected lifetime of 60 years and the lifetime extension of existing plants AREVA is focussing R and D activities on improved detection methods. Primary objective is the realistic determination of the actual usage level of reactor components. The fatigue monitoring is supposed to enhance cost optimization and minimize inspection frequency. Fatigue monitoring should be implemented at the beginning of start-up period since the high loads during this phase introduce a significant contribution to the usage level. AREVA recommends the use of the FAMOS (fatigue monitoring system) for the assessment of the realistic transient loads and the data processing with respect to fatigue evaluation. Every 10 years the actual usage levels should be evaluated in detail according to the standards, based on measured load data. The fatigue evaluation is usually performed using finite element analyses taking into account the transient temperature loads at the component, dependent on the component demands based on elastic or elasto-plastic material behaviour. Potential problematic areas can be identified reliably. Direct measurement of fatigue damage, refined analysis concepts (short crack fracture mechanics, and ratcheting simulation) are supposed to support the concept.

Analysis of the procedure proposed by AREVA to prove adequate toughness of the domes of the Flamanville 3 EPR reactor pressure vessel (RPV) lower head and closure head. Session of 30 September 2015. Public version

International Nuclear Information System (INIS)

Catteau, R.; Cadet-Mercier, S.

2015-01-01

AREVA has asked ASN to evaluate the conformity of the reactor pressure vessel (RPV) for the Flamanville 3 EPR in application of the order reference [6]. The domes of the Flamanville 3 RPV closure head and lower head were manufactured in 2006 and 2007. AREVA identified that these components displayed a risk of heterogeneity of their characteristics and therefore carried out a technical qualification. At the end of 2014, AREVA informed ASN of lower-than-expected results of impact tests conducted as part of this technical qualification on test specimens taken from a dome representative of those intended for Flamanville 3. The values measured on two series of three test specimens give a mean value of 52 joules which does not attain the quality standard expected by AREVA. This mean value is also lower than the bending rupture energy value of 60 joules mentioned in point 4 of appendix 1 of the order reference [6], with which compliance would have been sufficient to prove the toughness of the material. AREVA carried out investigations to determine the origin of these noncompliant values. The carbon concentration measurements taken at the surface of the representative dome by portable spectrometry revealed the presence of a zone of major positive segregation (high concentration of carbon) over a diameter of about one meter. Furthermore, the examinations show that the segregation extends to a depth exceeding a quarter of the thickness of the dome. AREVA explains the non-compliance with the bending rupture energy criterion by the presence of this major positive segregation which came from the ingot used for the forging and was not completely eliminated by the cropping operations. To deal with this deviation, AREVA plans proving that the material is sufficiently tough by conducting new tests on a material that is representative of the lower and upper domes of the Flamanville EPR reactor. The body of the Flamanville 3 RPV, of which the lower dome is a part, has already

The nuclear renaissance and AREVA's reactor designs for the 21st century. EPR and SWR-1000

International Nuclear Information System (INIS)

Stosic, Z.V.

2007-01-01

Hydro and nuclear energy are the most environmentally benign way of producing electricity on a large scale. Nuclear generated electricity releases 38 times fewer greenhouse gases than coal, 27 times fewer than oil and 15 times fewer than natural gas [9]. On a global scale nuclear power annually saves about 10% of the global CO 2 emission. European nuclear power plants save amount of CO 2 emissions corresponding with the annual emission of CO 2 from all European passenger cars [16]. Also, that is approximately twice the total estimated quantity to be avoided in Europe under the Kyoto Protocol during the period 2008-2012. In respect to main drivers - such as concerns of the global warming effect, population growth, and future energy supply shortfall, low operating costs, reduced dependence on imported gas - it is clear that 30 new nuclear reactors currently being constructed in 11 countries and another 35 and more planed during next 10 years confirm the nuclear renaissance. Participation in the construction of 100 reactors out of 443 worldwide operated in January 2006 and supplying fuel to 148 of them AREVA helps meet the 21 st century's greatest challenges: making energy available to all, protecting the planet, and acting responsibly towards future generations. With EPR and SWR-1000, AREVA NP has developed advanced design concepts of Generation III+ nuclear reactors which fully meet the most stringent requirements in terms of nuclear safety, operational reliability and economic performance.

Energy supply is increasingly showing up as a major issue for electricity supply, transportation, settlement, and process heat industrial supply including hydrogen production. Nuclear power is part of the solution. For electricity supply, as exemplified in Finland and France, the EPR brings an immediate answer; HTR could bring another solution in some specific cases. For other supply, mostly heat, the HTR brings a solution inaccessible to conventional nuclear power plants for very high or even high temperature. As fossil fuels costs increase and efforts to avoid generation of Greenhouse gases are implemented, a market for nuclear generated process heat will develop. Following active developments in the 80's, HTR have been put on the back burner up to 5 years ago. Light water reactors are widely dominating the nuclear production field today. However, interest in the HTR technology was renewed in the past few years. Several commercial projects are actively promoted, most of them aiming at electricity production. ANTARES is today AREVA's response to the cogeneration market. It distinguishes itself from other concepts with its indirect cycle design powering a combined cycle power plant. Several reasons support this design choice, one of the most important of which is the design flexibility to adapt readily to combined heat and power applications. From the start, AREVA made the choice of such flexibility with the belief that the HTR market is not so much in competition with LWR in the sole electricity market but in the specific added value market of cogeneration and process heat. In view of the volatility of the costs of fossil fuels, AREVA's choice brings to the large industrial heat applications the fuel cost predictability of nuclear fuel with the efficiency of a high temperature heat source free of greenhouse gases emissions. The ANTARES module produces 600 MWth which can be split into the required process heat, the remaining power drives an adapted prorated

The French approach through the SMR consortium (CEA, EDF, AREVA, DCNS)

The SMR (Small Modular Reactor) is a new range of nuclear reactors characterized by a low output power (less than 300 MWe) and a standardized modular factory-based construction. Moderate capital costs make this type of reactor very attractive for medium-size power utilities or small countries. A consortium made around the CEA and its industrial partners (EDF, AREVA and DCNS) has performed economic and technical feasibility studies. It appears that the competitiveness of SMR require power production costs around 100 euros/MWh and that SMR will be based on PWR technology with a power output of 150 MWe per unit. 2 types of SMR are proposed: a terrestrial unit and an immersed unit. The concept of the immersed SMR, called Flexblue, is based on an unlimited access to a cold sink (the ocean) and a complete modularity. In both types the standard of safety appears to be high.

The AREVA customized chemical cleaning C3-concept as part of the steam generator asset management

International Nuclear Information System (INIS)

Weiss, Steffen; Drexler, Andreas

2012-09-01

with various chemical cleaning methods and their world wide applications AREVA has developed the 'C 3 ' Customized Chemical Cleaning concept. This concept covers the entire range of steam generator chemical cleaning. With this approach, also specific problems like removal of sludge piles from tube sheet can be adequately addressed. At European PWRs the above presented overall approach was applied successfully in 2009 and 2010. Prior to the chemical cleaning the steam generator status was investigated and evaluated in a common approach of all relevant AREVA departments. For example, as a result of one plant specific evaluation, a hard sludge problem was identified combined with denting indications mainly on the tube sheet. Based on this SG assessment and the expected amount of deposits an individually tailored and site specific cleaning approach was developed in close cooperation with the plant operator. Prior to the chemical cleaning an inner bundle lancing was performed to mechanically weaken the hard deposits, which allows deep penetration of the cleaning agent into the deposits. The chemical cleaning methodology for this site specific SG problem was the AREVA DART HT process selected from the C 3 toolbox. The DART HT process allows an efficient removal of hard deposits, while keeping the average corrosion below 50 μm. After the chemical cleaning a subsequent tube sheet lancing was performed, effectively removing the chemically softened deposits. This approach removed the targeted amount of deposits, thus eliminating the hard sludge denting of tubes at the tube sheet. This paper describes the joint approach of the plant operator and AREVA for the on-site chemical cleaning to the improve steam generator condition. (authors)

Areva at September 30, 2013: Backlog of euro 42 bn Robust revenue growth to euro 6.847 bn: +4.7% vs. Sept. 2012 (+7.6% like for like) Strong organic growth (+9.9%) in the nuclear operations

2013-01-01

After a remarkable first half and as anticipated, Areva's third quarter revenue was stable in the nuclear operations compared with the third quarter of 2012. Globally, Areva's nuclear operations generated organic growth of 10% in the first nine months of 2013. This performance demonstrates the strength of Areva's commercial positions in the installed base market, where the company continues to innovate while improving its competitiveness. The success of Areva's integrated offers and of its Safety Alliance and Forward Alliance programs are perfect examples of this. Moreover, agreements signed for the EDF project at Hinkley Point strengthen Areva's position in the new builds market and bolster the credibility of Areva's EPR TM offers to other customers. In the Renewable Energies BG, revenue is below Areva's Action 2016 plan outlook, mainly due to the current indecisiveness in the renewable markets. Based on Areva's performance over the past nine months, the company confirms its revenue outlook for its business as a whole in 2013. AREVA generated consolidated revenue of 6.847 billion euros in the first nine months of 2013, representing growth of 4.7% (+7.6% like for like) compared with the same period in 2012. Revenue growth was fueled by a 7.7% increase in recurring business (+11.0% like for like). Revenue from nuclear operations was 6.453 billion euros in the first nine months of 2013, compared with 6.035 billion euros in the first nine months of 2012, a 6.9% increase (+9.9% like for like). Revenue was led by growth in all nuclear Business Groups (BG): the Mining BG (+31.8% like for like), the Front End BG (+9.8% like for like), the Reactors and Services BG (+1.5% like for like) and the Back End BG (+10.3% like for like). Revenue fell 24.6% like for like in the renewable operations. Foreign exchange had a negative impact of 71 million euros during the period. The change in consolidation scope had a negative impact of 106 million euros. In the third quarter of 2013

AREVA presents its 2016-2020 road-map and announces the group's restructuring through the creation of a new entity refocused on the nuclear fuel cycle

2016-01-01

In line with the announcements made in February 2016, for the publication of its 2015 annual results, AREVA confirms its plan to restructure the group and to create a separate entity refocused on the nuclear fuel cycle, currently named 'NEW CO'. In this press release, the group presents its 2016-2020 road-map, centered on the stages foreseen for its strategic and operational refocusing plan, and its financial objectives for 2020. Pursuant to strategic choices concerning the nuclear industry, the road-map specifies the conditions for the transfer of AREVA's reactor-related operations to EDF and the refocusing of the group on fuel cycle management. Thus dissociated and simplified in their organizations, AREVA and NEW CO will each benefit from a capital increase in the combined amount of 5 billion euros (subject to the approval of the European Commission) and will have resources suited to their mission and their strategy. By means of the solutions it can provide for uranium supply, for its conversion into fuel, and for nuclear fuel recycling, waste management and dismantling, NEW CO will be in a good position to grow in global nuclear markets. The strengthened capital structure, the new industrial plants, and the reinforcement of NEW CO's technology and innovation base will underpin this strategy

Global expertise of the ten-year environmental assessment (1993-2004) of AREVA NC.3. part: reuse of deads in the public field

International Nuclear Information System (INIS)

2008-01-01

The present document corresponds to the third and last phase of the global critical analysis of the ten-year environmental assessment. It has for objective to evaluate the knowledge on the conditions of reuse, in the public area, of deads coming from the sites of Limousin and to propose an exploratory analysis of conceivable actions to complete this knowledge in order to better identify the sectors and, or, the potentially risk uses. At this day, the knowledge on the transfer of deads and their use in the public field rests on the data recorded in a register implemented by Areva Nc from 1984. According to the transfers anterior to 1984, the situation of knowledge especially about the places of destination and purpose are poor. The analysis of Areva NC data allowed to I.R.S.N. to identify the areas of improvement of knowledge. The first one consists in achieving information concerning deads occurring before 1984. the second one aims to check that every use of deads in the 1984-1995 period are compatible with the exposure levels.

2011-01-01

On December 13, 2011, Luc Oursel, CEO, and Pierre Aubouin, Chief Financial Officer presented the group's strategic plan for the period 2012-2016. The plan has been drawn up collectively and is based on a thorough-going analysis and a realistic assessment of perspectives for all group activities and associated resources. Development of nuclear and renewable energies: the fundamentals are unchanged. In this context, the German decision remains an isolated case and the great majority of nuclear programs around the world have been confirmed. More conservative in its projections than the International Energy Agency, the group expects growth of 2.2% annually, reaching 583 GW of installed nuclear capacity by 2030, against 378 GW today. However, the Fukushima accident will lead to delays in launching new programs. 'Action 2016' plan aims to consolidate AREVA's leadership in nuclear energy and become a leading player in renewable energy. The group's strategic action plan 'Action 2016' is based on the following strategic choices: - commercial priority given to value creation, - selectivity in investments, - strengthening of the financial structure. These demand an improvement in the group's performance by 2015. This plan makes nuclear safety a strategic priority for the industrial and commercial performance of the group. This ambitious performance plan for the period 2012-2016 will give the group the wherewithal to withstand a temporary slowdown in the market resulting from the Fukushima accident and to deliver safe and sustainable growth of the business. The plan sets out the strategic direction for the group's employees for the years ahead: taking advantage of the expected growth in nuclear and renewable energies, targeted investment programs, and return to self-financing as of 2014

This report presents a synthesis of the most recent information on the both public companies, EDF and AREVA, within the context of their industrial sector. While discussing hypotheses and assessments of future expenses, the report outlines that future expenses related to the electronuclear activity are well provisioned in the accounts of both companies, but that their value is probably under-estimated. As far as EDF is concerned, the authors outline that the international development strategy impacted investment and partnership choices, and that the company should review this posture within a new context. As far as Areva is concerned, they think that the company possesses the required assets to be revived, but this requires rigorous financial and industrial choices

The author comments the answers to a call for tender made by the French government and concerning five offshore wind farm sites (Le Treport, Fecamp, Courseulles sur Mer, Saint-Brieuc and Saint-Nazaire). As they are present within the three consortiums, Areva and Alstom should provide the wind turbines. This would result in the construction by Alstom of two blade and mast factories and two turbine and pad factories. For both companies, this market of 500 to 600 turbines is an opportunity. Many jobs are at stake. They push themselves forward for their experience or their innovation capacity. But their wind turbines will be based on foreign (Spanish or German) technology

Areva - Revenue up by 6% in the first half of 2009

International Nuclear Information System (INIS)

2009-01-01

In Nuclear, the levels of activity among the various divisions and their contribution to revenues can vary significantly from one half of the year to the next, which affects relative group performance over the period in question. Like-for-like growth for the first half of 2008 had thus reached 18.6% compared to the first half of 2007, due to several positive events, in particular exceptional sales in Asia in the Front-End division, favourable seasonality in Services, and a very high concentration of production in Recycling (Back-End). These events, which resulted in achieving more than 80% of nuclear 2008 operating income in the first six months and about 48% of sales revenues, illustrate the non-representative nature of the half-year performance in terms of usual profitability profile of nuclear activities. As of June 30, 2009, AREVA had a backlog of 48.9 billion euro, up 28.2% compared to June 30, 2008 and a slight increase compared to end of year 2008. In Nuclear, the backlog of orders came to 42.9 billion euro at June 30, 2009, 32.7% ahead of figures for June 30, 2008. In Transmission and Distribution, the order backlog on June 30, 2009 came to 6.0 billion euro, an increase of 3.0% over one year. In the first half of 2009, AREVA recorded revenues of 6,522 million euro, representing a 5.7% rise (+2.8% like-for-like) compared to the first half of 2008. Revenues outside France were up 12% to 4,758 million euro or 73% of total revenues. In the first half, revenue from Nuclear businesses came to 3,906 million euro, remaining stable compared to the same period last year (-2.9% LFL). The Transmission and Distribution division recorded revenues of 2,614 million euro, up 14.5% (+12.5% LFL), illustrating a good flow in the order backlog for Products (+11.8% LFL) and Systems (+15.1% LFL). Sales revenue for the second quarter of 2009 rose to 3,519 million euro, for growth of 3.5% (+1.9% LFL) compared with the second quarter of 2008. The Nuclear division recorded sales

Many countries spread all over the world have publicly expressed their intention to pursue the construction of new nuclear power plants with improved safety, economy and more straight forwarded operation and maintenance. Reasons for the intention are: The world wide increasing demand for energy and hence the general necessity to build new power plants. The concerns for increased emissions of green house gases leading to a change in the climate have brought into question the primary reliance on plants utilizing fossil fuels. A new reactor type matching the previously stated issues is AREVA NP's further development of proven BWR design. Combining AREVA's and E.ON's expertise, a project was launched to customize the final basic design for this advanced nuclear power plant having a net power output of about 1,250 MW, a net efficiency of about 37% and a design service life of 60 years. Within this joint venture the overall plant design was simplified and additionally all active safety systems have passive safety related backup systems utilizing basic laws of physics, such as gravity, enabling them to function without electrical power supplies or activation by powered instrumentation and control systems. The development takes into account the technical and accumulated operating experience of the project partners. Based on the operating experience of the project partners a simplification of the overall system engineering was performed, flexible fuel cycle length (12 to 24 months) are possible as well as a reduction of process waste was achieved. These improvements regarding the operation and economics result on the one hand in lower investment cost and on the other hand in a high availability of the plant, hence in low maintenance costs. Generally, the electrical generation costs are accomplished, which are competitive to larger-capacity nuclear power plants and fossil-fired plants. (author)

Established with engineering and manufacturing operations in the US and Europe, AREVA NP has been and is supplying nuclear fuel assemblies and associated core components to boiling water reactors worldwide, representing today more than 63 000 fuel assemblies. The evolution of BWR fuel rod arrays from early 6x6 designs to the 10x10 designs first introduced in the mid 1990's yielded significant improvements in thermal mechanical operating limits, critical power level, cold shutdown margin, discharge burnup, as well as other key operational capabilities. Since first delivered in 1992, ATRIUM T M 1 0 fuel assemblies have now been supplied to a total of 32 BWR plants in the US, Europe, and Asia resulting in an operating experience over 20 000 fuel assemblies. This article presents in detail the operational experience consolidated by these more than 20 000 ATRIUM T M 1 0 BWR assemblies already supplied to utilities. Within the different 10x10 fuel assemblies available, the Fuel Assembly design is chosen and tailored to the operating strategies of each reactor. Among them, the latest versions of ATRIUM T M a re ATRIUM T M 1 0XP and ATRIUM T M 1 0XM fuel assemblies which have been delivered to several utilities worldwide. The article details key aspects of ATRIUM T M 1 0 fuel assemblies in terms of reliability and performance. Special attention is paid to key proven features, ULTRAFLOW T M s pacer grids, the use of part length fuel rods (PLFRs) and their geometrical optimization, water channel and load chain, upgraded features available for inclusion with most advanced designs. Regular upgrading of the product has been made possible thanks to a continuous improvement process with the aim of further upgrading BWR fuel assembly performance and reliability. Regarding thermal mechanical behavior of fuel rods, chromia (Cr2O3) doped fuel pellets, described in Reference 1, well illustrate this improvement strategy to reduce fission gas release, increase power thresholds for PCI

Modelling the transfer of 14C from the atmosphere to grass: A case study in a grass field near AREVA-NC La Hague

Radioactive 14 C is formed as a by-product of nuclear power generation and from operation of nuclear fuel reprocessing plants like AREVA-NC La Hague (North France), which releases about 15 TBq per year of 14 C into the atmosphere. Since the autumn of 2006, 14 C activity concentrations in samples from the terrestrial environment (air, grass and soil) have been monitored monthly on grassland 2 km downwind of the reprocessing plant. The monitoring data provides an opportunity to validate radioecology models used to assess 14 C transfer to grassland ecosystems. This article compares and discusses the ability of two different models to reproduce the observed temporal variability in grass 14 C activity in the vicinity of AREVA-NC La Hague. These two models are the TOCATTA model which is specifically designed for modelling transfer of 14 C and tritium in the terrestrial environment, and PaSim, a pasture model for simulating grassland carbon and nitrogen cycling. Both TOCATTA and PaSim tend to under-estimate the magnitude of observed peaks in grass 14 C activity, although they reproduce the general trends. PaSim simulates 14 C activities in substrate and structural pools of the plant. We define a mean turn-over time for 14 C within the plant, which is based on both experimental data and the frequency of cuts. An adapted PaSim result is presented using the 15 and 20 day moving average results for the 14 C activity in the substrate pool, which shows a good match to the observations. This model reduces the Root Mean Square Error (RMSE) by nearly 40% in comparison to TOCATTA. - Highlights: ► We model 14 C transfer from the atmosphere to grass near AREVA-NC reprocessing plant. ► Both models considered under-estimate the observed variability and highest peaks. ► A model based solely on the sap 14 C activity and mean turn-over time is considered. ► It performs well and could be applied to case studies around nuclear facilities.

Transition from power generation to decommissioning challenges utilities. Power generation is mainly characterized by a stable working environment and constant workload, decommissioning and dismantling, however, by transformation and change. Also, changing requirements for the workforce's skills challenge the organization and its senior management. Ensuring effective and efficient performance, while maintaining motivation of staff, requires adjustment of management processes as well as of operational organization and human resources management. AREVA has more than 20 years of experience in decommissioning of own nuclear fuel cycle plants in France, as well as of other large plants and power reactors in Germany, the United Kingdom and the US. Therefore, the group has developed and successfully implemented integrated change management processes. The implementation of well-established and proven methods, developed by the productive industry and adjusted to the nuclear regulatory requirements, significantly improves the performance and efficiency of means and methods in use. The AREVA Performance Improvement Process defines concrete approaches to identify and improve potential deficits of productivity in six main areas (decommissioning scenarios and stra-tegies, waste treatment and logistics, operations management, supply chain, regulatory monitoring and controls as well as dismantling operation). Nuclear plant and facility owners around the world benefit from AREVA experts well experienced in execution of large and complex decommissioning projects.

As AREVA displays an unprecedented loss, and is facing a durable and persistent stagnation of its nuclear activities after the Fukushima accident, and as these losses are the consequences of misguided strategic decisions and disputable mining acquisitions, as well as of a problematic management of the main big industrial projects, this report comes after an intervention of the French President on the future of this company. The objectives are a restoration of Areva's competitiveness, and the elaboration of a new partnership between EDF and AREVA with a new definition of their respective roles in the design, manufacturing and selling of nuclear reactors. Notably based on hearings, and on visits of the Flamanville EPR site and of the La Hague reprocessing plant this reports aims at informing the French parliament on the different faced challenges and opportunities. The authors thus give an overview of the group financial situation and describe the important reorganisation issues. They analyse how the group has been weakened by its economic performance and a development mode with uncertain results. They try to define a possible future within the frame of a reorganised nuclear sector based on a high performance group, a good governance of the nuclear sector, an industrially consistent solution, and a relevant position for the French nuclear sector

This report for the Swiss Federal Office of Energy presents in tables and diagrams the results of a survey involving 421 households in Switzerland, about their awareness to energy issues and, in particular, to all what regards wind energy and wind power plants. Globally, 80% of the persons asked for their opinion believe that electric power demand will continue to increase. 66% of them are in favour of increased use of renewable energy sources and would consequently agree with a 10% more expensive end-user energy price. 89% of the persons taking part to the survey approve the installation of wind energy farms in Switzerland. Moreover, statistics indicates that the households living in regions already equipped with wind farms are significantly more favorable to the creation of new wind energy sites than those not living in these regions. By the end of the day, it turns out that the main reasons for accepting wind energy are environmental concerns as well as the fear of being obliged to use nuclear power.

Bordy, Michel

2004-01-01

Operating as a global company, inside AREVA the Fuel Sector implements a common strategy among three Business Units of fuel activities. These Business Units which are in Framatome ANP Zirconium, Manufacturing and Design and Sales Units, are operated in Germany (former Siemens activity), in USA (former BWFC Babcock and Wilcox Fuel Co,. and SPC Siemens Power Co. activities), in Belgium and in France (former Framatome activity). They have resources and facilities which are cooperatively working on R and D, engineering, project management, sales and services to achieve synergy on a cross-business basis. Based on its experience of worldwide activities and taking advantage of its diversified fuel design knowledge, Framatome ANP proposes a full range of fuel products and services on the BWR and PWR markets. With the ability to supply all fuel assembly arrays and fuel pellet types, supplemented by the range of stationary and movable core components, and completed by a full-range of on-site fuel services and performance of fuel packing and delivery, Framatome ANP is positioned as a major participant on the world fuel market. Today, Framatome ANP takes advantage of the cross-fertilization in the short term of existing products which include four original PWR fuel designs of HTP TM alloy as the reference material for cladding tubes, guide thimbles, and grids, -- Gradual incorporation of the valuable high-stiffiness MONOBLOC tM guide thimble, -- Progressive integressive integration of the High Mechanical Performance (HMP) Inconel end grid, -- Planned standardization of mechanical components such as nozzles, holddown systems and top and bottom connections. As a continuation of its existing technology, Framatome ANP is developing improved technical features within the scope of the Alliance fuel assembly qualification program. With an irradiation program ranging up to a burnup of 70 MWd/kgU expected to be reached in 2006, Alliance shows excellent behaviour with very low corrosion

For the last seven years, AREVA/COGEMA has been implementing the second phase of its burn-up credit program (the incorporation of fission products). Since the early nineties, major actinides have been taken into account in criticality analyses first for reprocessing applications, then for transport and storage of fuel assemblies Next year (2004) COGEMA will take into account the six main fission products (Rh103, Cs133, Nd143, Sm149, Sm152 and Gd155) that make up 50% of the anti-reactivity of all fission products. The experimental program will soon be finished. The new burn-up credit methodology is in progress. After a brief overview of BUC R and D program and COGEMA's application of the BUC, this paper will focus on the new burn-up measurement for UO2 and MOX fuel assemblies. It details the measurement instrumentation and the measurement experiments on MOX fuels performed at La Hague in January 2003. (author)

The French Government most enthusiastically promotes development of bio-gasoline in renewable energy field. EU makes pressure to remove the French Government`s fiscal advantages for bio-gasoline which only benefit French farmers, and the IEA (International Energy Agency) report also estimates no benefit corresponding to the fiscal support cost. Start of the `Eolien 2005` project is attractive in renewable energy field which aims at construction of wind power generation stations of 250-500MW by 2005. The `Eolien 2005` project is mainly supported by Electricite de France (EDF) who guarantees the purchase of produced electric power at a submitted price. In addition to this subsidy activity, EDF decided to positively tackle renewable energy. On R and D efforts for renewable energy, France belongs to the most poor countries among IEA countries, and in addition, the effort is considerably concentrated onto the study on reduction of production cost for bio-gasoline. There were no changes in this situation in 1996. 7 refs., 5 figs., 31 tabs.

Phase 1A Final Report for the AREVA Team Enhanced Accident Tolerant Fuels Concepts

Energy Technology Data Exchange (ETDEWEB)

Morrell, Mike E. [AREVA Federal Services LLC, Charlotte, NC (United States)

2015-03-19

In response to the Department of Energy (DOE) funded initiative to develop and deploy lead fuel assemblies (LFAs) of Enhanced Accident Tolerant Fuel (EATF) into a US reactor within 10 years, AREVA put together a team to develop promising technologies for improved fuel performance during off normal operations. This team consisted of the University of Florida (UF) and the University of Wisconsin (UW), Savannah River National Laboratory (SRNL), Duke Energy and Tennessee Valley Authority (TVA). This team brought broad experience and expertise to bear on EATF development. AREVA has been designing; manufacturing and testing nuclear fuel for over 50 years and is one of the 3 large international companies supplying fuel to the nuclear industry. The university and National Laboratory team members brought expertise in nuclear fuel concepts and materials development. Duke and TVA brought practical utility operating experience. This report documents the results from the initial “discovery phase” where the team explored options for EATF concepts that provide enhanced accident tolerance for both Design Basis (DB) and Beyond Design Basis Events (BDB). The main driver for the concepts under development were that they could be implemented in a 10 year time frame and be economically viable and acceptable to the nuclear fuel marketplace. The economics of fuel design make this DOE funded project very important to the nuclear industry. Even incremental changes to an existing fuel design can cost in the range of $100M to implement through to LFAs. If this money is invested evenly over 10 years then it can take the fuel vendor several decades after the start of the project to recover their initial investment and reach a breakeven point on the initial investment. Step or radical changes to a fuel assembly design can cost upwards of $500M and will take even longer for the fuel vendor to recover their investment. With the projected lifetimes of the current generation of nuclear power

2012-01-01

The Particular intervention plan (PPI in French) is an emergency plan which foresees the measures and means to be implemented to address the potential risks of the presence and operation of a nuclear facility. This plan is implemented and developed by the Prefect in case of nuclear accident (or incident leading to a potential accident), the impact of which extending beyond the facility perimeter. It represents a special section of the organisation plan for civil protection response (ORSEC plan). The PPI foresees the necessary measures and means for crisis management during the first hours following the accident and is triggered by the Department Prefect according to the information provided by the facility operator. Its aim is to protect the populations leaving within 10 km of the facility against a potential radiological hazard. The PPI describes: the facility, the intervention area, the protection measures for the population, the conditions of emergency plan triggering, the crisis organisation, the action forms of the different services, and the post-accident stage. This document is the public version of the Particular intervention plan of the Areva NC La Hague fuel reprocessing plant (located on the territories of Beaumont-Hague, Digulleville, Herqueville, Jobourg and Omonville-la-Petite towns, Manche, France) which comprises the totally decommissioned UP2 400 unit, and the UP2 800 production unit still in operation

Chartier, D.; Sanchez-Canet, J.; Avril, D.; Roussel, C.; Pineau, J.N.

Wastes have been temporarily stored in dedicated silos in La Hague reprocessing plant. These wastes are to be retrieved in the near future and to be conditioned for final disposal. Some of these wastes are supposed to be encapsulated in cement matrix and, depending on the chemical composition of the waste streams, several projects are presently ongoing. The present article aims to focus on one amongst these cement encapsulation relevant projects, namely the conditioning of a mix of spent ion-exchange resins (from filtration of pool) and fine particles (insoluble fission products from spent fuel dissolution and Zircaloy and stainless steel fines from cladding shearing). The project, aims to retrieve these wastes from a silo, separate the resins and fine particles from the other waste (hulls and end pieces), in order to encapsulate the intermediate-level fines and resins in a cement matrix. The waste forms will be produced in AREVA's La Hague reprocessing plant, prior to being sent as intermediate-level waste to a long-term repository. The cement formulation developments were initially carried out at a small scale at C.E.A. Marcoule on surrogate wastes. One of the main issues that were considered was the chemical compatibility between waste and cement matrix. Indeed, swelling phenomena are sometimes reported when ion exchange resins are embedded in cement matrixes such as Portland cement. This kind of destructive phenomenon has been prevented by the use of cement containing a high amount of ground granulated blast furnace slag. The impact of the variability of ionic charge of the resins on the waste form's properties has also been addressed in order to comfort the results obtained on the reference ionic charge of resins NaNO 3 . Once the results obtained were satisfactory, intermediate scale and full scale tests were performed by AREVA. These tests have focused on adjusting the mixing process and controlling the thermal properties of the mix during setting

Multilevel criticality computations in AREVA NP'S core simulation code artemis - 195

International Nuclear Information System (INIS)

Van Geemert, R.

2010-01-01

This paper discusses the multi-level critical boron iteration approach that is applied per default in AREVA NP's whole-core neutronics and thermal hydraulics core simulation program ARTEMIS. This multi-level approach is characterized by the projection of variational boron concentration adjustments to the coarser mesh levels in a multi-level re-balancing hierarchy that is associated with the nodal flux equations to be solved in steady-state core simulation. At each individual re-balancing mesh level, optimized variational criticality tuning formulas are applied. The latter drive the core model to a numerically highly accurate self-sustaining state (i.e. with the neutronic eigenvalue being 1 up to a very high numerical precision) by continuous adjustment of the boron concentration as a system-wide scalar criticality parameter. Due to the default application of this approach in ARTEMIS reactor cycle simulations, an accuracy of all critical boron concentration estimates better than 0.001 ppm is enabled for all burnup time steps in a computationally efficient way. This high accuracy is relevant for precision optimization in industrial core simulation as well as for enabling accurate reactivity perturbation assessments. The developed approach is presented from a numerical methodology point of view with an emphasis on the multi-grid aspect of the concept. Furthermore, an application-relevant verification is presented in terms of achieved coupled iteration convergence efficiency for an application-representative industrial core cycle computation.

Operational HOF Practices in the AREVA Group to Face New Challenges

International Nuclear Information System (INIS)

Coye de Brunélis, T.; Bachellerie, E.; Sidaner, J.-F.

2016-01-01

Operating experience from TMI and and more general experience from three decades of nuclear facility operations, have shown the value of safety culture’s contribution to nuclear risk management. More than ever, this particular aspect of human and organizational factors (HOF) is central to the AREVA group’s concerns as it faces new challenges. The first generation of operators commissioned the facilities and optimized their operation. This first phase gave them a better understanding of operations and related limits, particularly through testing and start-up operations and the responses that were found for all of the technical issues that arose. All of these interactions offered opportunities to make the safety challenges of processes and facilities tangible and directly perceptible. The young operators of those bygone years are now the ones who are “in the know” in the organizations, the ones with unique technical know-how and a multi-layered perception of the risks involved. Those first generations of operators, with their unique operational knowledge, are gradually leaving the industrial world. Replacing those skills creates a new set of challenges. Concomitantly, the French nuclear safety authority benefited from these facility start-ups to increase its skills by sharing in the learning process concerning the facilities’ operational realities and in the construction of a safety configuration program, and by gaining a concrete perception of risk. This fostered the mutual trust that is vital and integral to facility safety.

The results for the first half of 2012 demonstrate the effectiveness of Areva's 'Action 2016' plan, in particular with a sharp rise in EBITDA and a significant improvement in free operating cash flow after capex. Moreover, net debt remains stable even though the Group invested more than 900 million euros in strategic projects and in improvements to safety and to competitiveness of industrial assets. Several factors made this first phase towards restoring the Group's financial performance possible: - revenue growth in the nuclear businesses together with the ramp-up of operations in renewable energies, with the Group continuing to benefit from the strong visibility provided by its backlog, which has also grown over the past twelve months; - ongoing efforts begun in late 2011 to reduce operating costs, with savings measures at the end of June 2012 implemented for nearly 20% of the objective set for the Group through 2015, on an annual basis, another 45% of the objective being secured in addition. - execution ahead of schedule in Areva's asset disposal program, with 961 million euros mainly collected during the first half year and the objective of at least 1.2 billion euros for the 2012- 2013 period to be met this year with the recently announced disposal of La Mancha Resources for about 315 million Canadian dollars. After booking provisions, in accordance with the principle of prudent management, in two areas (construction of the Olkiluoto 3 EPR reactor and the Bakouma and Ryst Kuil mining sites), the Group reports positive operating income and positive net income for the first half of 2012. Results can be summarized as follows: Backlog rises 4.8% year on year to euro 45.2 bn; - Significant revenue growth to euro 4.329 bn, up 8.3% vs. H1 2011; - Strong increase in EBITDA to euro 725 m: +euro 508 m vs. H1 2011; - Marked improvement in FCF to -euro 591 m: +euro 328 m vs. H1 2011; - Net debt stable for the half year; - Positive operating income and net income to owners

Task Order 22 – Engineering and Technical Support, Deep Borehole Field Test. AREVA Summary Review Report

Denton, Mark A. [AREVA Federal Services, Charlotte, NC (United States)

2016-01-19

Under Task Order 22 of the industry Advisory and Assistance Services (A&AS) Contract to the Department of Energy (DOE) DE-NE0000291, AREVA has been tasked with providing assistance with engineering, analysis, cost estimating, and design support of a system for disposal of radioactive wastes in deep boreholes (without the use of radioactive waste). As part of this task order, AREVA was requested, through a letter of technical direction, to evaluate Sandia National Laboratory’s (SNL’s) waste package borehole emplacement system concept recommendation using input from DOE and SNL. This summary review report (SRR) documents this evaluation, with its focus on the primary input document titled: “Deep Borehole Field Test Specifications/M2FT-15SN0817091” Rev. 1 [1], hereafter referred to as the “M2 report.” The M2 report focuses on the conceptual design development for the Deep Borehole Field Test (DBFT), mainly the test waste packages (WPs) and the system for demonstrating emplacement and retrieval of those packages in the Field Test Borehole (FTB). This SRR follows the same outline as the M2 report, which allows for easy correlation between AREVA’s review comments, discussion, potential proposed alternatives, and path forward with information established in the M2 report. AREVA’s assessment focused on three primary elements of the M2 report: the conceptual design of the WPs proposed for deep borehole disposal (DBD), the mode of emplacement of the WP into DBD, and the conceptual design of the DBFT. AREVA concurs with the M2 report’s selection of the wireline emplacement mode specifically over the drill-string emplacement mode and generically over alternative emplacement modes. Table 5-1 of this SRR compares the pros and cons of each emplacement mode considered viable for DBD. The primary positive characteristics of the wireline emplacement mode include: (1) considered a mature technology; (2) operations are relatively simple; (3) probability of a

Areva revenue and data for the first quarter of 2008

International Nuclear Information System (INIS)

2008-01-01

First quarter 2008 revenue was up 12.1% year-on-year, to 2.769 billion euros. Like-for-like (at constant exchange rates and consolidation scope), growth came to 14.5%. Foreign exchange had a negative impact of 2.5%, or -69 million euros, mainly due to currency translation tied to the US dollar drop compared with the euro. The consolidation scope had a positive impact of +0.7% or 18 million euros, chiefly as a result of the consolidation of VEI Distribution (specializing in medium voltage distribution) and Passoni and Villa (world leader in the manufacture of high voltage bushings) in the Transmission and Distribution division. The main growth engines for first quarter revenue were the Reactors and Services division and the Back End division, with growth of 29.7% (+36.8% LFL1) and 13.8% (+14.1% LFL1) respectively. Outside France, revenue rose to 1.857 billion euros, compared with 1.753 billion euros in the first quarter of 2007. This represents 67% of total revenue. As a reminder, the group points out that: - revenue can vary significantly from one quarter to the next in the nuclear businesses, and quarterly operations should therefore not be taken as a reliable basis for annual projections; - the foreign exchange impact mentioned in this release comes from the translation of subsidiary accounts into the group's unit of account, and primarily reflects the US dollar in relation to the euro. AREVA also points out that its foreign exchange hedging policy for commercial operations aims to shield profitability from fluctuations in exchange rates in relation to the euro

Zero tolerance for failure. An AREVA initiative to improve reliability

International Nuclear Information System (INIS)

Lippert, Hans-Joachim; Gentet, Guy; Mollard, Pierre; Garner, Norman

2010-01-01

Significant improvements in fuel reliability have been realized over the past 2 decades, but total elimination of failures has remained elusive. Driving reliability to higher levels requires a philosophy that does not accept that even infrequent and isolated failures are inevitable - it was on this foundation that Areva's Zero Tolerance for Failure (ZTF) initiative was established. This is not in itself either a program or project, but a fundamental shift in the way of thinking about work according to the following four principles: - Failures are avoidable, - Zero failures are our goal, - We will respond rapidly to any failure, - We succeed when we fix failures in a way that precludes recurrence. The shift to a ZTF philosophy is a broad change in corporate culture that expands the concept of failure far beyond cases where fuel rod cladding integrity is breached. While this paper specifically illustrates the ways in which ZTF has shaped the company's response to enhancing fuel rod reliability, ZTF extends to any failures of fuel products to deliver expected levels of performance, manufacturing processes to meet specifications and high first-pass acceptance criteria, and beyond to error-free performance of engineering analyses and cycle design and licensing services. Application of ZTF to enhancing fuel reliability deploys efforts in the areas of manufacturing, human factors, design, R and D, processes and product strategy. In order to achieve the necessary improvements, a number of important actions have been initiated across regions and facilities. In addition to these global scale projects and measures, each region contributes by adopting measures which are relevant to its particular activities and market needs. (orig.)

In light of the inspections, appraisals and coordination missions it has performed, the General Inspectorate considers that the nuclear safety level of the AREVA group's nuclear installations is satisfactory. It particularly noted positive changes on numerous sites and efforts in the field of continuous improvement that have helped to strengthen nuclear safety. This has been possible through the full involvement of management teams, an improvement effort initiated by upper management, actions to increase personnel awareness of nuclear safety culture, and supervisors' heightened presence around operators. However, the occurrence of certain events in facilities has led us to question the nuclear safety repercussions that the changes to activities or organization on some sites have had. In these times of change, drifts in nuclear safety culture have been identified. The General Inspectorate considers that a preliminary analysis of the human and organizational factors of these changes, sized to match the impact the change has on nuclear safety, should be made to ensure that a guaranteed level of nuclear safety is maintained (allowance for changes to references, availability of the necessary skills, resources of the operating and support structures, etc.). Preparations should also be made to monitor the changes and spot any telltale signs of drift in the application phase. Managers should be extra vigilant and the occurrence of any drift should be systematically dealt with ahead of

Two years after Fukushima, AREVA's level of activity was especially strong in 2013. The group outperformed its revenue outlook for nuclear operations with an organic growth of 7.1%. With more than 9 billion euros, the group's revenue benefited from the robustness of the recurring activities and from temporary elements, such as exceptionally high uranium sales. This growth demonstrates the resilience of Areva's end market, despite unfavourable current conditions, and the efficient match between its commercial offers and customers' expectations. Capitalizing on this dynamic, the group will continue its recovery in order to sustainably self-finance its capital expenditures. After the announcement on January 20, 2014 of exclusive negotiations with Gamesa for the creation of a joint company in the offshore wind field (50% AREVA, 50% Gamesa), and in accordance with IFRS 5 accounting standard, revenue generated by the Wind Energy business is not included in group revenue for 2012 and 2013 and the result of this business will be presented on a separate line, 'net income from discontinued operations' in the 2013 financial statements. In 2013, AREVA had consolidated revenue of 9.303 billion euros, an increase of 3.8% (+6.3% like for like) compared with 2012 benefiting from strong organic growth in the nuclear operations: - Revenue in the nuclear operations was 9.042 billion euros in 2013, compared with 8.633 billion euros in 2012, a 7.1% increase (+4.7% on a reported basis). Revenue was led by the Mining BG (+40.6% like for like) and the Front End BG (+7.5% like for like), offsetting the expected business downturn in the Reactors and Services BG (-1.5% like for like). Revenue was stable in the Back End BG (-0.6% like for like). - The Renewable Energies BG had 132 million euros in revenue, down from 2012 (-24.7% like for like). - Foreign exchange had a negative impact of 101 million euros, while the change in consolidation scope and accounting methods had a negative impact of

First quarter 2008 revenue was up 12.1% year-on-year, to 2.769 billion euros. Like-for-like (at constant exchange rates and consolidation scope), growth came to 14.5%. Foreign exchange had a negative impact of 2.5%, or -69 million euros, mainly due to currency translation tied to the US dollar drop compared with the euro. The consolidation scope had a positive impact of +0.7% or 18 million euros, chiefly as a result of the consolidation of VEI Distribution (specializing in medium voltage distribution) and Passoni and Villa (world leader in the manufacture of high voltage bushings) in the Transmission and Distribution division. The main growth engines for first quarter revenue were the Reactors and Services division and the Back End division, with growth of 29.7% (+36.8% LFL1) and 13.8% (+14.1% LFL1) respectively. Outside France, revenue rose to 1.857 billion euros, compared with 1.753 billion euros in the first quarter of 2007. This represents 67% of total revenue. As a reminder, the group points out that: - revenue can vary significantly from one quarter to the next in the nuclear businesses, and quarterly operations should therefore not be taken as a reliable basis for annual projections; - the foreign exchange impact mentioned in this release comes from the translation of subsidiary accounts into the group's unit of account, and primarily reflects the US dollar in relation to the euro. AREVA also points out that its foreign exchange hedging policy for commercial operations aims to shield profitability from fluctuations in exchange rates in relation to the euro.

Following the marked growth of the nuclear operations in 2013, thanks in particular to the strength of recurring activities and the contribution of exceptional items such as significant uranium sales volumes and non-recurring foreign contracts, revenue in the first quarter of the year fell sharply, as Areva had anticipated. A strong seasonal effect will materialize in 2014, with greater activity to be expected in the second half of the year. As indicated when releasing 2013 annual results, the current economic environment is still unfavorable, with market prices deteriorating in the front end of the cycle and lackluster demand from customers for installed base services. AREVA's operations generated consolidated revenue of 1.781 billion euros in the first quarter of 2014, a decrease of 18.1% (-17.3 % like for like) compared with the same period in 2013. The Front End Business Group (BG) reported strong growth of +59.0% (+59.8% like for like). Revenue was down in the Mining, Reactors and Services, Back End and Renewable Energies BGs, at -63.0% (-62.3% like for like), -14.1% (-12.5% like for like), -41.7% (-41.6% like for like) and -38.2% (-34.6% like for like) respectively. Foreign exchange had a negative impact of 18 million euros over the period, while the change in consolidation scope had a negative impact of 3 million euros. The group's backlog reached 40.2 billion euros at March 31, 2014, a decrease of 2.9% compared with December 31, 2013 and of 8.8% year on year

Narrow gap mechanised arc welding in nuclear components manufactured by AREVA NP

International Nuclear Information System (INIS)

Peigney, A.

2007-01-01

Nuclear components require welds of irreproachable and reproducible quality. Moreover, for a given welding process, productivity requirements lead to reduce the volume of deposited metal and thus to use narrow gap design. In the shop, narrow gap Submerged Arc Welding process (SAW) is currently used on rotating parts in flat position for thicknesses up to 300 mm. Welding is performed with one or two wires in two passes per layer. In Gas Tungsten Arc Welding process (GTAW), multiple applications can be found because this process presents the advantage of allowing welding in all positions. Welding is performed in one or two passes per layer. The process is used in factory and on the nuclear sites for assembling new components but also for replacing components and for repairs. Presently, an increase of productivity of the process is sought through the use of hot wire and/or two wires. Concerning Gas Metal Arc Welding process (GMAW), its use is growing for nuclear components, including narrow gap applications. This process, limited in its applications in the past on account of the defects it generated, draws benefit from the progress of the welding generators. Then it is possible to use this efficient process for high security components such as those of nuclear systems. It is to be noted that the process is applicable in the various welding positions as it is the case for GTAW, while being more efficient than the latter. This paper presents the state of the art in the use of narrow gap mechanised arc welding processes by AREVA NP units. (author) [fr

Remarks on the radiological situation in the vicinity of the uranium mines operated by SOMAIR and COMINAK (subsidiaries of AREVA) in northern Niger. Study conducted on behalf of Greenpeace International

International Nuclear Information System (INIS)

2010-01-01

The companies SOMAIR and COMINAK, subsidiaries of the AREVA group, are mining uranium deposits in northern Niger near the towns of Arlit and Akokan. In the course of a mission carried out in November 2009, a Greenpeace International team took radiation measurements in situ, collected samples, and amassed a number of documents provided by the companies. The aim of this mission was to evaluate how the radiological situation has developed in the vicinity of the industrial sites operated by SOMAIR and COMINAK. The CRIIRAD laboratory, which carried out earlier missions and studies at Arlit between 2003 and 2009 (list at Annex 1) helped to accomplish this mission by drawing up a list of documents to be requested from AREVA (Annex 2) and devising a sampling and analysis strategy. The sampling procedures and radioprotection instructions were discussed during a preliminary meeting at the CRIIRAD laboratory on 7 October 2009, between Dr Rianne Teule (chemist, Greenpeace International) and Dr. Bruno Chareyron (nuclear physics engineer in charge of the CRIIRAD laboratory). The analysis at the CRIIRAD laboratory of the samples brought back by Greenpeace in November 2009 is discussed in CRIIRAD reports nos. 10-05 (soil analysis) and 10-07 (analysis of radon in the air). The results of the radiological and chemical analysis of five water samples taken by Greenpeace in the Arlit-Akokan district and, as a control, one sample taken in the Imouraren district are reproduced in Annex 4 and discussed in the present report. The present report represents a summary of the CRIIRAD laboratory's preliminary observations and recommendations on the basis of the analysis conducted and of a preliminary examination of the documents listed in Annex 3. Three subjects are addressed: the presence of radioactive material in the environment; air contamination by a radioactive gas, radon 222; and contamination of groundwater which supplies the local population. A more in-depth analysis of the available

The purpose of this document is to provide physicians working in a B.N.F. (Basic Nuclear Facility) with recommendations for the drafting of Ca-DTPA treatment protocols for internal contamination by actinides. These recommendations are based on the results of injections carried out by Cea and AREVA doctors in a working group, with the collaboration of the Army Radiation Protection Service. The study focused on Ca-DTPA IV injection. Other dosage forms, routes of administration as well as adjuvant treatments are also mentioned. For cases of contaminated wounds and inhalation, indicators for treatment with Ca-DTPA, particularly its initialization, the dosage, duration, frequency of administration, the criteria for ending the treatment, then its efficiency and dosimetry gain are covered. A guide for the prescription of the radio toxicological monitoring necessary for the treatment and the dosimetric evaluation is proposed. (authors)

The aim of this work was to study the near-field dispersion of (85)Kr around the nuclear fuel reprocessing plant at La Hague (AREVA NC La Hague - France) under stable meteorological conditions. Twenty-two (85)Kr night-time experimental campaigns were carried out at distances of up to 4 km from the release source. Although the operational Gaussian models predict for these meteorological conditions a distance to plume touchdown of several kilometers, we almost systematically observed a marked ground signal at distances of 0.5-4 km. The calculated atmospheric transfer coefficients (ATC) show values (1) higher than those observed under neutral conditions, (2) much higher than those proposed by the operational models, and (3) higher than those used in the impact assessments.

Synthesis of the IRSN report on arrangements proposed by AREVA, the CEA and the ILL about the implementation of a 'hard core' for installations related to the fuel cycle and for research reactors falling within batch 1

International Nuclear Information System (INIS)

2013-01-01

After additional safety assessments performed by operators of French nuclear installations, the ASN ask them to implement a 'hard core' of material and organisational arrangements to prevent any severe accident or its propagation, to limit massive releases within a scenario of accident which could not have been controlled, and to allow the operator to ensure its assigned missions in crisis management, to present an organisation and means of crisis management which would remain operational in case of extreme aggressions, and to foresee transient arrangements before the implementation of the crisis management hard core. This report proposes a synthesis of the assessment performed by the IRSN on these issues. It addresses issues on which hard cores are defined (earthquakes, flooding, other climatic aggressions, effects induced by an extreme aggression), requirements associated with material arrangements of hard cores. The content of these hard cores is then discussed for AREVA installations (La Hague, MELOX, Romans-sur-Isere, Tricastin), CEA installations and the high flow reactor of the Laue Langevin Institute. Measures concerning crisis management and, for AREVA, the taking of human and organisational factors into account by these operators are also discussed

Remarks on the Cogema-Areva project of storage of contaminated sludge and sediments on the Bellezane site (Haute-Vienne). Investigation performed by the CRIIRAD laboratory on its own funds

International Nuclear Information System (INIS)

2006-06-01

As sediments of several lakes are contaminated by uranium mines which are located upstream, and which have been exploited in the past by the Cogema (now Areva NC), this company asked for an authorization to use an old pit in Bellezane to deposit clearing sludge from water processing plants and from the clearing of ponds. This document describes the different problems raised by this project. It outlines that the site is not waterproof and that its legal status is not correct. It also reports and comments the radiological contamination of waters and soils due to site effluents, the chemical contamination of waters, and the existence of solid radioactive wastes at the vicinity of this site

The AREVA C3 concept. Customized chemical cleaning as an essential part of steam generator asset management

International Nuclear Information System (INIS)

Weiss, Steffen

2011-01-01

As the nuclear industry moves forward and the world's power demand increases, the continued safe, reliable, and efficient operation of existing plants has become indispensable. For these plants asset management is an essential factor. A crucial part of the plant assets are the steam generators (SG). Not only that the SG tubes are by far the largest boundary between the primary and secondary sides, they are also instrumental in the overall performance of the plant. The main concern for operational lifetime is tube degradation due to either ID or OD corrosion. At the secondary side, sludge and corrosion products accumulate in the SG resulting in the buildup of secondary side deposits. Such deposits can negatively affect the SG performance in different ways, not only by reduction of the heat transfer rates and, thus, by reducing the efficiency of the SG but also as cause or promotion of different types of corrosion phenomena. The cleanliness of the secondary side of SG is of essential interest to all utilities. There is not just one solution for SG asset optimization. The utilities must weigh the pros and cons of SG cleaning, with the associated impact on outage time and cost, versus the potential benefits. Each plant that considers a SG chemical cleaning has different objectives and goals. AREVA has developed the C 3 (Customized Chemical Cleaning - or in short 'C cubed') concept in order to provide the utility with a chemical cleaning method that is tailored to the needs of the individual units and that addresses them directly.

2014-06-01

This annual report by AREVA's General Inspectorate deals with the status of nuclear safety and radiation protection in the group's facilities and operations over the course of 2013. Based on the findings made during implementation of the annual inspection program, this annual report also includes the results of the analysis of significant events and the observations and assessments of specialists in the Safety Health Security Sustainable Development Department (SHSSDD), supplemented by regular interaction with the safety regulators, different government agencies, stakeholders and other nuclear operators. Additionally, this report presents the action plans put into motion and the directions taken for continuous improvement in risk prevention for operations conducted in France and internationally. In 2013, the level of safety in the group's nuclear facilities and operations remained satisfactory, although improvements are necessary in some domains. This report is based on established indicators, analyses of reported events, responses to commitments made to the regulators, and the results of different improvement actions reported on in the inspected and supported entities. In 2013, no level 2 event on the International Nuclear and Radiological Event Scale (INES) was reported, the bottom-up reporting of weak signals was confirmed, dose levels were low and there were no radiological impacts on the environment. The General Inspectorate conducted 45 inspections in 30 of the group's entities in 2013. Of these, 10 concerned sites outside France and 7 were conducted following events or particular situations. These inspections gave rise to 176 recommendations, which the inspected entities have translated into action plans. Verification of these different action plans according to planned procedures and announced schedules gave rise to 16 follow-up inspections. The major lessons learned from these inspections relate to project management, facility compliance and operational

DIWA trademark. AREVA's approach of intelligent computer-aided support of water chemistry monitoring in power plants

International Nuclear Information System (INIS)

Fandrich, Joerg

2011-01-01

The complexity of power plant operation makes stringent demands on the chemical quality of the coolant in process systems and loops. Optimal water chemistry ensures high corrosion resistance of these systems and is thus essential for safe and economic long term plant operation. The market offers a huge variety of commercial software packages for water chemistry control. Most of these computer programs have to be considered as data analysis or, respectively, data acquisition programs. Some of them require manual data input (Laboratory Information Management Systems), others are capable of performing a fully automated data acquisition. However, the plant operator typically is left alone with the actual interpretation of all collected and validated data, which would be the main characteristic feature of an analysis (or monitoring) system. The data validation is typical being performed by means of numerical methods in the broadest sense. This activity requires a long working experience and specific skills by the plant chemistry operator. True diagnostic systems need to be significantly more advanced. They contain the capability of data interpretation and derivation of specific diagnoses. This is combined with additional explanations on how the diagnoses were derived. Additionally, further recommendations are offered on how to proceed to reach the normal operational behavior as soon as possible. AREVA's DIWA trademark system features a fuzzy logic expert system that is based on expert knowledge. It is built on symptoms, which are combined in rules as part of the fuzzy tool set. These components can be edited without programming knowledge, which significantly reduces training efforts. It makes the system more robust, more compact and simpler compared to other so-called expert systems. DIWA trademark represents the knowledge in a natural way, in which other conventional expert system may have difficulties or need a larger set of rule algorithms. (orig.)

As a consequence of the nuclear phase-out decreed by the German government, several nuclear power plants in the country have already ceased operation. The remaining ones will cease operation by 2022. This has turned Germany into one of the most active regions worldwide in the field of nuclear decommissioning, with new and emerging technologies being deployed on the field, and already preexisting technologies being put to the test, optimized and developed into full maturity. The chemistry services division of AREVA GmbH has already performed 5 Full System Decontaminations (FSD) in preparation for decommissioning in this period - three in PWRs and two in BWRs - along with other international projects of relevance for decommissioning operations. During a FSD, the complete primary circuit of a nuclear power plant including auxiliary systems is subject to a chemical treatment; designed to remove radioactive matter accumulated onto system surfaces during operation. Through the effective removal of this radioactive accumulations contact dose rates on the different components of the primary circuit can be consistently reduced by factors larger than 50. This results in much lower ambient dose rates and, hence, in very significant dose savings for subsequent decommissioning activities. Additionally, dismantlement operations of large components are considerably simplified and can be performed under conditions that wouldn't have been possible before. The project specific objectives and challenges, the technologies employed, and the results obtained are presented and commented here. (authors)

Global expertise of the ten-year environmental situation of AREVA N.C.1. part: storage of Bellezane and environmental impact at the level of the Ritord catchment basin

International Nuclear Information System (INIS)

2007-01-01

The first step of the expertise of the ten-year environmental assessment of Areva Nc was focused on the storage of mine residues of Bellezane and on the environmental impact of mine exploitation at the level of the Ritord watershed, these two aspects being appeared as a priority as regard to the different concerns and topical. The I.R.S.N. analysis consisted in checking that the impacts associated to the presence of residues are correctly controlled. The specificity of the storage system face to the water control rest on the capacity of water collect that have circulated at the residues contact and on their treatment before release. Concerning the exposure by emission in atmosphere, the characteristics of the roofing, particularly its thickness, allow to reduce significantly the residues contribution to the ambient gamma radiation and radon emission. The measured dose rate appear linked to the radiological content of deads themselves and rocks constituting the surrounding landscape. (N.C.)

Health effects of low dose exposures to external ionizing radiation in the French cohort of nuclear workers CEA-AREVA-EDF - 5287

Populations of nuclear workers are particularly relevant to study health effects of low dose and low dose-rate exposures to ionizing radiation. In France, a cohort of nuclear workers employed by CEA, AREVA NC, or EDF, and badge-monitored for radiation exposure, has been followed-up. Annual exposure to penetrating photons was reconstructed for each worker. Standardized mortality ratios were calculated using national mortality rates as the reference. Estimates of radiation dose-mortality associations were obtained using a linear excess relative risk (ERR) model. A total of 59,004 workers were followed-up between 1968 and 2004, for an average of 25 years. The mean cumulative photons dose was 16.1 mSv. At the end of the follow-up, workers were 56 years old and 6,310 workers had died. A strong healthy worker effect was observed. Positive but imprecise estimates of ERR/Sv were observed for all solid cancers and leukemia excluding chronic lymphocytic leukemia. A significant ERR/Sv was found for myeloid leukemia. This cohort study is the most informative ever conducted in France among nuclear workers. Results confirmed a healthy worker effect due to selection at hiring and health monitoring from occupational medicine. Observed dose-risk relationships were consistent with risks estimated in other studies, even if they remained associated to a large uncertainty. (authors)

2008-01-01

The nuclear new build market is dynamic: the nuclear renaissance is here. The challenge facing today the nuclear industry is to meet this strong demand: design and build new reactors..... and ensure an adequate fuel supply for the existing reactors and the new ones. AREVA is getting ready to meet those needs. To answer in the best possible way the call of several new customers, and to make the necessary investments AREVA has made the choice of complementing its own strength with new alliances. When it was created, AREVA has set a new model: an integrated group capable of supplying all parts of the nuclear cycle, from Uranium mining to reactor design construction and servicing, and then up to used fuel management and recycling. This merger of reactor activities and fuel cycle services has proved successful. Focused acquisitions have further strengthened our own capabilities. In addition, AREVA has set-up several alliances to further develop the nuclear market. In the United States, AREVA joined forces with the US utility Constellation to create Uni Star to promoting the EPR. Today, several US utilities are choosing the AREVA's US-EPR. They will benefit from the experience gained in licensing and building the EPR in Finland, in France and soon in China. And they will benefit of course from the unique features of the EPR: easier maintenance, shorter outage, enhanced safety. Willing to meet the growing demand of countries launching a new nuclear program, AREVA set up an alliance with MHI to design a mid-size reactor, ATEMEA 1. Such an alliance allows to speed-up time to market of this new product, which will offer the latest available technologies. In the fuel cycle, AREVA has also developed acquisitions and alliances. As an example, thanks to such an alliance, the new enrichment plant GB-2, could get access to the most efficient centrifugation process. In this fast growing global market, at AREVA we believe into the value of collaboration and partnership to best serve

Nuclear measurements are used at AREVA NC/La Hague for the monitoring of spent fuel reprocessing. The process control is based on gamma-ray spectroscopy, passive neutron counting and active neutron interrogation, and gamma transmission measurements. The main objectives are criticality and safety, online process monitoring, and the determination of the residual fissile mass and activities in the metallic waste remained after fuel shearing and dissolution (empty hulls, grids, end pieces), which are put in radioactive waste drums before compaction. The whole monitoring system is composed of eight measurement stations which will be described in this paper. The main measurement stations no. 1, 3 and 7 are needed for criticality control. Before fuel element shearing for dissolution, station no. 1 allows determining the burn-up of the irradiated fuel by gamma-ray spectroscopy with HP Ge (high purity germanium) detectors. The burn-up is correlated to the {sup 137}Cs and {sup 134}Cs gamma emission rates. The fuel maximal mass which can be loaded in one bucket of the dissolver is estimated from the lowest burn-up fraction of the fuel element. Station no. 3 is dedicated to the control of the correct fuel dissolution, which is performed with a {sup 137}Cs gamma ray measurement with a HP Ge detector. Station no. 7 allows estimating the residual fissile mass in the drums filled with the metallic residues, especially in the hulls, from passive neutron counting (spontaneous fission and alpha-n reactions) and active interrogation (fission prompt neutrons induced by a pulsed neutron generator) with proportional {sup 3}He detectors. The measurement stations have been validated for the reprocessing of Uranium Oxide (UOX) fuels with a burn-up rate up to 60 GWd/t. This paper presents a brief overview of the current status of the nuclear measurement stations. (authors)

The vitrification of high-level liquid waste produced from nuclear fuel reprocessing has been carried out industrially for over 25 years by AREVA/COGEMA, with two main objectives: containment of the long lived fission products and reduction of the final volume of waste. At the 'La Hague' plant, in the 'R7' and 'T7' facilities, vitrified waste is obtained by first evaporating and calcining the nitric acid feed solution-containing fission products in calciners. The product-named calcinate- is then fed together with glass frit into induction-heated metallic melters to produce the so-called R7/T7 glass, well known for its excellent containment properties. Both facilities are equipped with three processing lines. In the near future the increase of the fuel burn-up will influence the amount of fission product solutions to be processed at R7/T7. As a consequence, in order to prepare these changes, it is necessary to feed the calciner at higher flow-rates. Consistent and medium-term R and D programs led by CEA (French Atomic Energy Commission, the AREVA/COGEMA's R and D and R and T provider), AREVA/COGEMA (Industrial Operator) and AREVA/SGN (AREVA/COGEMA's Engineering), and associated to the industrial feed back of AREVA/COGEMA operations, have allowed continuous improvement of the process since 1998: - The efficiency and limitation of the equipment have been studied and solutions for technological improvements have been proposed whenever necessary, - The increase of the feeding flow-rate has been implemented on the improved CEA test rig (so called PEV, Evolutional Prototype of Vitrification) and adapted by AREVA/SGN for the La Hague plant using their modeling studies; the results obtained during this test confirmed the technological and industrial feasibility of the improvements achieved, - After all necessary improved equipments have been implemented in R7/T7 facilities, and a specific campaign has been performed on the R7 facility by AREVA/COGEMA.

For the AREVA group training is more than just transferring knowledge skills. It also means developing attitudes and meeting the changing challenges of people development, of its customer's employees and of its own employees. AREVA wants to meet the world's energy challenges and has therefore taken on the mission of enabling as many as possible to have access to energy that is clean, safe and economical. In order to meet this greatest challenge of the 21 st century with its growing demand for energy, AREVA requires a rapid increase of its global workforce. This means that 45.000 new recruits must be hired by 2012. In particular the rapid growth of AREVA's Reactors and Services division due to its business development produces an increasing demand for effective training services in order to prepare the newly recruited employees for their professional activities.

2006-03-01

This document reports the study of health risks related to the chemical toxicity of species related to the operation of several AREVA installations in Tricastin. A qualitative and quantitative inventory of the species released in the atmosphere and in waters is based on data supplied by the operator. A selection of health tracers has lead to a global investigation of nitrogen oxides, sulphur dioxide, fluorine, uranium, arsenic, hexavalent chromium, mercury and nickel. The hazard associated with each of these species has been characterized. Different exposure ways have been considered: inhalation, soil ingestion, by vegetable, fruit and crop ingestion, ingestion of meat, milk and eggs produced by local breeding, fish ingestion, and ingestion of water sampled from the Tricastin aquifer. Atmospheric concentrations, soil deposits, surface soil layer concentrations, and other concentrations (in meat, milk, eggs, crops, vegetables, fruits, and drinking water) have been either modelled or measured. Different exposure scenarios have been defined, and the different risks (carcinogen or not) have been assessed

Nuclear industry achieves about 20% of its turnover with the export of equipment and services but nuclear trade is submitted to specific constrains like non-proliferation policies. According to IAEA the world capacity of nuclear power is expected to double allowing the development of emerging countries while reducing CO_2 emissions. The French commercial offer focuses on the high-end market with the EPR reactor and an intermediate power range reactor ATMEA-1 designed with MHI (Mitsubishi Heavy Industries). AREVA is the unique world operator able to master the entire chain of spent fuel reprocessing thanks to the La Hague plant. In the framework of the rebuilding of the French nuclear industry, discussions are ongoing to achieve partnerships with foreign partners in exchange of shares in AREVA and AREVA NP. Today's main challenges of AREVA are to reduce EPR cost, to speed EPR construction and to benefit fully of the move into the digital age. (A.C.)

Bessines: Rebirth of a technological excellence center

International Nuclear Information System (INIS)

2014-06-01

Areva's mining activity is rooted in the Limousin region of central France. For over 65 years, Bessines-sur-Gartempe has been closely involved with global energy and industrial issues. Geologists came here first as explorers, followed by miners and chemical engineers. This is the heritage on which Areva is drawing to help satisfy the steadily growing demand for energy. The SEPA's (Service d'etudes, de Procedes et Analyses) role is to develop new ways to process and use mineral ores. A world renowned R and D center, modernizing its research facilities is a key part of the program to revitalize the Bessines site. Between 1947 and 2001, close to 250 mining sites were exploited in France producing 76,000 tons of uranium. The Areva group (through the CEA and COGEMA) operated 55 % of these sites, all of which have been reclaimed today. UREKA is an educational center created by Areva to inform the public about uranium mining and French know-how in this field. This museum is unique in the world of mining. Depleted uranium is a byproduct of the uranium enrichment process. It harbors real energy potential that Areva intends to tap in the future. The effectiveness of lead-212 in targeting and destroying cancer cells was demonstrated several years ago. The Geosciences Center in made of four entities spread over 4,000 m 2 , regrouping the whole of Areva's mining knowledge and history. The wealth of mineralogical, petrographic and documentary data found there has been accumulated over more than 60 years of exploration and mining

The NGNP program is developing the High Temperature Reactor for high efficiency electricity production and high temperature process heat such as direct hydrogen production. AREVA leads one of three vendor teams supporting the NGNP program. AREVA has developed an NGNP concept based on AREVA's ANTARES indirect cycle HTR concept. The ANTARES-based NGNP concept attempts to manage development risk by using a conservative design philosophy which balances performance and risk. Additional risk mitigation for rapid near-term deployment is also considered. Near-term markets may not require the full capability of the indirect cycle very high temperature concept. A steam cycle concept might better serve near-term markets for high temperature steam with reduced technical and schedule risk. (authors)

In 2002, the Finnish Government gave the go-ahead for construction of the country's fifth nuclear power plant unit. In December of 2003, the AREVA NP/Siemens Consortium was awarded a turnkey contract by the Finnish utility Teollisuuden Voima Oy (TVO) to build a new nuclear power plant at the Olkiluoto site where two boiling water reactor units are already in operation. Olkiluoto 3 is an EPR, and thus the world's very first third generation nuclear power plant under construction. The reactor is being supplied by AREVA NP, the turbine and generator by Siemens. AREVA NP, which is head of the consortium, is responsible for overall project management as well as technical and functional integration. (author)

Full text: The AREVA group, which is committed to offering its customers technological solutions for reliable CO 2 -free power generation, is both a designer and vendor of nuclear units and operator of nuclear facilities. The group's ambitions are to maintain its knowledge capabilities and develop skills at the level necessary to respond to its business objectives around the world. The AREVA Human Resources department has developed an action plan to support business strategy which aims to accelerate its investment in people, to reinforce recruitment and retain high quality talents and valuable skills and knowledge. Today, there is a global challenge for attracting the best talent and becoming an employer of choice. The group must be creative in attracting, retaining, mobilising, engaging, developing and rewarding its people. AREVA has 61 100 employees worldwide, of which 38 000 work in nuclear activities. In 2006, some 10% of the nuclear workforce represented newcomers, and the group anticipates recruiting a similar significant ratio in 2007. The group has to be ready to tackle a surge in recruitment which is believed will continue over the next 5 years. AREVA has developed, on an international level, networks and partnerships with academic institutions. New programs are being created and promoted to prepare for the integration of future skills needed in the nuclear business. The group has coordinated and pooled resources to gain efficiencies and to strengthen its presence on the employment market. Plans are in place for employee integration and development, mobility, and managing the transfer of knowledge and specific skills. In this context, internal professional training paths are being developed and reinforced, including geology of uranium, dismantling, reactors, nuclear safety and the environment. AREVA is developing a common methodology to lever the transfer of knowledge through training modules, sharing experience and mentoring. Mentoring programs have been

The Flamanville EPR reactor pressure vessel closure and bottom head domes were manufactured in 2006 and 2007 by forging in the Areva NP Creusot Forge plant. These components are subject to the technical qualification requirement of the ESPN order in reference because they present a risk of heterogeneity in their properties. For the purposes of this technical qualification, Areva NP measured bending rupture energy values lower than those mentioned in point 4 of appendix I to the ESPN order in reference [3], which led it in 2015 to propose an approach to ASN to demonstrate the adequate toughness of the material of these components, based on a program of testing on scale-one replica domes and mechanical assessments of the risk of fast fracture. This approach was examined by ASN and the French institute for radiation protection and nuclear safety (IRSN) and written up in the report in reference, was the subject of an opinion in reference of the Advisory Committee of experts for nuclear pressure equipment (GP ESPN), which met on 30 September 2015, and of ASN requests, more specifically concerning the in-service inspection provisions, in its letter in reference. Subject to these requests being taken into account, ASN considered that the demonstration approach is appropriate, provided that the phenomenon in question is identified and explained and that the data acquired through the test program are sufficient to characterise it. The first test results, in April 2016, led Areva NP to change its demonstration approach, notably the test program on scale-one replica domes, which gave rise to an information meeting with the GP ESPN on 24 June 2016, on the basis of the summary report drawn up by ASN and IRSN in reference. On the basis of the observations of the GP ESPN in reference, ASN informed Areva NP of additional requests in its letter in reference. The Areva NP test program was conducted for the most part in 2016. On 16 December 2016, Areva NP sent ASN a file in reference

Georges Besse 2. A new era for enrichment

International Nuclear Information System (INIS)

2009-01-01

Since 1978, AREVA group subsidiary EURODIF's Georges Besse plant has been using gaseous diffusion to enrich uranium and meet the requirements of electricity utilities. Georges Besse II plant, which will use far less electricity, will replace George Besse not so long. The Georges Besse II plant is located on the Tricastin nuclear site in southern France. AREVA ensure delivery of uranium enrichment services in accordance with customer expectations. AREVA obtained the right to use URENCO's centrifugation technology on July 3, 2006. This is the process to be used at Georges Besse II. The new uranium enrichment plant will comprise two enrichment units, with a total production capacity of 7.5 million separative work units, which can be extended to 11 million if needed. Each enrichment unit will include: a Centrifuge Assembly Building (CAB), a Centrifuge Utility Building (CUB) with offices and control room, annexes for purification, supply and extraction of uranium hexafluoride (UF 6 ), modules containing the halls that house the centrifuge cascades. The modular design of the Georges Besse II plant will allow production in the first cascade where as the others cascades are build. The first cascade should be operational in the first half of 2009. At an overall cost of 3 billion euros, this project is one of the largest investments of the decade in France On November 24, 2003, AREVA and URENCO signed an agreement under which AREVA would buy 50% of the shares in the Enrichment Technology Company (ETC), which designs and manufactures centrifuges

Global NDE Best Practice for Technology Improvement, Outage Management, Foreign Material Exclusion and Dose Control

Glass, S. W.; Mohr, F.

2010-01-01

Non Destructive Examination (NDE) is a critical element of both Boiling Water and Pressurized Water Reactor outages. Frequently this includes critical path activity so both the utility and the inspection vendor are under intense pressure to perform the work quickly. Concurrent with AREVA's new global organization of NDE resources, AREVA NDE SOLUTIONS, efforts have intensified for global application of lessons learned and best practices. These best practices include new developments as well as continuous improvements to well established tools and NDE techniques. Advancements range from steam generator robots, advanced steam generator deposit characterization sensors and method, new phased array approaches for PWR and BWR reactor vessel examination, new sensors and approaches for RPV head examinations, plus advanced internals examination robots and methods. In addition to specialized tools and techniques, best practice includes numerous management innovations. AREVA's multi-disciplined integrated nuclear worker strategy helps to minimize the total number of personnel deployed to multi-task outages. Specific design and on-site practice has been implemented to minimize or eliminate foreign material from the reactor system and vigorous pursuit of dose management practices keeps our nuclear worker dose as low as reasonably achievable. The industry is moving to much more conservative nuclear worker dose limits. While this is proving to be an issue with many vendors, AREVA has had an internal policy of <2R since 2006. Globalizing the organization also helps AREVA manage peaks and unplanned emergency inspections from an enlarged pool of globally qualified inspection personnel and tools. (Author)

GRET started the title project in May 1990. About 50,000 people live in the area around Rosso, Mauritania, where the project is located. An essential aspect of the project is that villagers themselves need to ask for a wind pump. Moreover, the wind pumps are locally manufactured by a small enterprise. The counterparts are the Mauritanian Ministry of Energy, and the non-gouvernmental Institute Dello and Espace Eolien Regional in France. The Oasis multibladed windmill (2,5 diameter) was chosen, because it is easy to manufacture, it is easy to maintain and quite cheap. To avoid problems it is decided not to pump water from a depth more than 20 meters. The total costs of a wind pump amount to approximately US$ 8,000. for obtaining a wind pump, the villagers need to pay 15% of this total amount. 5 figs., 1 tab

In the wake of the March 11 earthquake and tsunami and the subsequent flooding of several of the Fukushima Dai-Ichi reactors, Japan and the Japanese utility TEPCO faced a crisis situation with incredible challenges: substantial amounts of radioactive mixed seawater and freshwater accumulated in the basements of four reactor and other buildings on the site. This water held varying levels of contamination due to the fact that it had been in contact with damaged fuel elements in the cores and with other contaminated components. The overall water inventory was estimated at around 110,000 tons of water with contamination levels up to the order of 1 Ci/l. Time was of the essence to avoid overflow of this accumulated water into the ocean. AREVA proposed, designed and implemented a water treatment solution using a proven chemical coprecipitation process with ppFeNi reagent, which is currently in use for effluent treatment on several nuclear sites including AREVA sites. In addition to the extremely short schedule the other challenge was to adapt the chemical treatment process to the expected composition of the Fukushima water and, in particular, to evaluate the impact of salinity on process performance. It was also necessary to define operating conditions for the VEOLIA equipment that had been selected for implementation of the process in the future facility. The operation phase began on June 17, and by the end of July more than 30,000 tons of highly radioactive saltwater had been decontaminated - the Decontamination Factor (DF) for Cesium was ∼10{sup 4}. It allowed recycling the contaminated water to cool the reactors while protecting workers and the environment. This paper focuses on the Actiflo{sup TM}-Rad water treatment unit project that was part of the TEPCO general water treatment scheme. It presents a detailed look at the principles of the Actiflo{sup TM}-Rad, related on-the-fly R and D, an explanation of system implementation challenges, and a brief summary of

The Supervisory Board of the AREVA group presents in this document the financial statements submitted by the Executive Board for the semester ended June 30, 2010. Areva backlog continued to rise in the first half of the year. Areva's revenue is up by more than 6% for the first six months to more than 4 billion euros. The performance of Areva's recurring business continues to improve, reflecting optimization plans deployed in all of the group's business units. However, Areva booked in the first half a non cash reversible accounting adjustment on the value of certain mining assets, following the publication in the second quarter of new prospective data on uranium prices, as well as an additional provision on the EPR project in Finland. Cumulated provisions on OL3 rose to 2.6 billion euros. Capitalizing on lessons learned from this project, Areva has reduced strongly the engineering hours needed for the completion of the nuclear steam supply system for the Taishan 1 and 2 EPR reactors. Net income attributable to owners of the parent rose to 843 million euros, including the 1.3 billion euro gain on the disposal of the Transmission and Distribution business, or 23.82 euros per share. For the full year of 2010, the group anticipates a substantial revenue and backlog growth, an increase in operating income excluding particular items, a negative operating income, and a strong increase in net income attributable to owners of the parent, which includes the capital gain on disposal of the Transmission and Distribution business. First half 2010 financial results in brief: - Backlog of euro 44.1 bn: +euro 1.2 bn compared with June 30, 2009; - Revenue of euro 4.158 bn: +6.4% compared with first half 2009; - Operating income excl. particular items: euro 213 m, for a 5.1% margin; - Operating income: -euro 485 m; - Net income group share: euro 843 m including the euro 1.27 bn gain on the sale of the T and D business; - Earnings per share: euro 23.82; - Net debt of euro 5.152 bn

PCI. Mechanism, measures, rules for reactor operation

Though modern and advanced fuel assembly designs for BWR as AREVA's ATRIUM trademark 10 fuel assemblies show a high reliability, fuel failures are still encountered. The ZTF (Zero Tolerance for Failures) initiative was launched by AREVA to further upgrade BWR fuel assembly reliability towards failure free fuel. The introduction of the zirconium liner cladding has greatly reduced pellet cladding interaction (PCI) failures. However the phenomenon of PCI in reactor operation was not completely eliminated. There were failures in AREVA's BWR fuel with liner cladding attributed to PCI, but when subject to hot cell examinations, all these have been attributed to ''non-classical'' PCI, where local cladding stress is amplified due to missing pellet surface (MPS). However, in order to support the efforts to eliminate all possible root causes for fuel failures, AREVA NP addresses PCI with a ''multi-track'' strategy. First, and most important, the development of chromia doped pellets and more favorable pellet geometries aim at fuel that by design is protected as much as possible against PCI. A high pellet quality is further assured by the final assessment of the pellet appearance by an automatic visual inspection system in the pellet manufacturing lines. In order to support these hardware improvements, AREVA NP provides software aimed to minimize PCI risks. Two main approaches are described in this paper: - The ''classical'' PCI operation and maneuvering guidelines restrict power maneuvering and limit the ramping rates with the goal to control the stress level of the cladding. AREVA's guidelines are based on ramp tests as well as on extensive power plant experience, and are updated to reflect the performance of liner cladding. - Additional effort is made to further understand the PCI phenomenon, e.g. by the use of detailed fuel rod thermal-mechanical codes that provide far better insight of the state variables that control the process of rupture due to stress corrosion

Full Text Available AREVA NC La Hague facility is the first step of the nuclear fuel recycling process implemented in France. The processing of the used fuel is governed by high standards of criticality-safety, and strong expectations on the quality of end-products. From the received used fuel assemblies, the plutonium and the uranium are extracted for further energy production purposes within the years following the reprocessing. Furthermore, the ultimate waste – fission products and minor actinides on the one hand, and hulls and end-pieces on the other hand – is adequately packaged for long term disposal. The used fuel is therefore separated into very different materials, and time scales which come into account may be longer than in some other nuclear fields of activity. Given the variety of the handled nuclear materials, as well as the time scales at stake, the importance given to some radionuclides, and hence to the associated nuclear data, can also be specific to the AREVA NC La Hague plant. A study has thus been led to identify a list of the most important radionuclides for the AREVA NC La Hague plant applications, relying on the running constraints of the facility, and the end-products expectations. The activities at the AREVA NC La Hague plant are presented, and the methodology to extract the most important radionuclides for the reprocessing process is detailed.

In order to quantify dose impact on members of the public due to annual discharges of its nuclear installations, AREVA developed the COMODORE code in collaboration with Institute of Radiation Protection and Nuclear Safety (IRSN). COMODORE is a synthesis of 3 software validated by IRSN (ACADIE, COTRAM and AQUAREJ). ACADIE is a code elaborated by IRSN and the Treatment Business Unit of AREVA synthesizing the works of the GRNC (Nord-Cotentin Radioecology Group) created by the French government to deal with the estimation of exposure levels to ionizing radiation and associated risks of leukemia for populations in the Nord-Cotentin. COMODORE is a version of ACADIE designed to be adaptable to any other AREVA site. Thus, the operators of the south east of France (Pierrelatte, Marcoule and Romans sites) carried out the adaptation of COMODORE for theirs specificities (for instance, uranium in the terrestrial model). At the moment, COMODORE is used in routine by the AREVA operators to assess the annual dosimetric impact and is also being adapted with SGN to model the radiological impact of uranium ore treatment residues repositories. This tool contributes to the transparency by giving stake holders environmental data they need. (author)

A first article comments the consequences of the Fukushima accident for the French nuclear sector: the risk of an extreme accident must be taken into account; this will result in works and investments; the cost of the French nuclear-based electricity will increase; the debate on the dismantling costs will be on again. Despite these problems, the French nuclear industry relies on its development perspectives abroad, notably in China. In an interview, the chairman of Areva discusses his first six months of action, evokes the implementation of the strategic action plan and the consequences of France's financial degradation, evokes the UraMin affair, the consequences of the Fukushima accident on Areva's offer, the costs of works required by the ASN, the perspectives for the EPR reactor, Areva's activities in the renewable energy sector. A last article comments the strategy of the German company Siemens who decided to phase out nuclear, and to focus notably of wind energy

This document gathers pieces of information from around the world concerning the nuclear sector. Among which were the following. Saudi-Arabia projects to build 16 nuclear reactors till 2020. In Pakistan the third reactor has entered into service, this reactor (Chashma-2, 330 MW) is a PWR-type reactor designed by CNNC (China National Nuclear Corporation). Areva Newport News LLC has postponed to a later date the construction of a plant dedicated to manufacturing big components like reactor vessels or vessel heads. Areva and Rhodia have signed an agreement for a better valorization of deposits involving uranium and rare earth elements. Bulgaria has inaugurated a new storage center for nuclear wastes. Areva has launched the construction of a plant dedicated to the production of Pb-212, an isotope used in the treatment of some cancers. A worker died of a fall on the building site of Flamanville-3. According to COMARE (Committee on Medical Aspects of Radiation in the Environment) there is no relationship between the child leukemia and the presence of nuclear power plants in U.K. Siemens has been condemned to pay 0.648 billion euros to Areva as a compensation for the breach of the shareholder pact. Rosatom has created Rosatom Overseas that will be in charge of financing, building, operating and even owning nuclear power plants on foreign soil. 'Electricite de France' has presented its trends for the next decade. (A.C.)

Siemens's spectrum of deliveries and services for nuclear power plants

International Nuclear Information System (INIS)

2011-01-01

In 2001, Siemens and Framatome merged their nuclear activities in the present Areva NP joint venture. Siemens has since focused on the construction and further development of conventional power plants and on the so-called conventional island (CI), the non-nuclear part of a nuclear power plant, i.e. the steam turbine, generator, and plant I and C systems, and also on service for the conventional part of nuclear power plants. Its role as a minority shareholder in Areva NP constrained Siemens. For this reason, the company in January 2009 decided to terminate its interest in Areva NP effective January 30, 2012. By January 2012 at the latest, Siemens will transfer to the majority shareholder Areva, holding 66 percent of the shares, its interest in the joint venture. For the time being, the joint venture still entails certain limitations to Siemens's activities in the nuclear field. Its delivery of the conventional island for the Olkiluoto 3 (OL3) nuclear power plant in Finland confirms the company's know-how in power plant construction. When commissioned, its 1,720 MW power will make OL3 the world's largest nuclear generating unit. The turbo-generator of the CI comprises a double-flow HP turbine and a 6-flow LP turbine. The driven 4-pole generator with a power of up to 2,200 MVA consists of a water-cooled stator and a hydrogen-cooled rotor. (orig.)

Environment managing all along the mining cycle: implementing an integrated and pro-active approach

International Nuclear Information System (INIS)

2017-01-01

Uranium mining is a niche business because of its production volume and the size of its market that have nothing to do with coal market or iron ore business. It is a very concentrated business with only a few players. New AREVA is one of them with an output of 11.186 tons of uranium representing 15% of the world production in 2016. New AREVA has committed oneself to preserve the environment during the exploitation phase of a mine. Environment samples (soil, water, plants...) are collected to draw an initial picture of a site before mining activities begin in order to minimize the environmental impact. In some sites, for instance in Mongolia, water is scarce and has to be spared, a recycling technology for the sludge recovered from drilling operations, has been tested with success. Another challenge is the adaptation to the climate warming as both a player and a victim because most sites are in zones that are very sensitive to climate change and because mining can release greenhouse effect gases. The final challenge that faces New AREVA at the end of a mining cycle is to succeed the remediation of the site, it does not mean a come back to the initial situation which is impossible to reach but to get an environmental state that is safe and durable. In 2011 AREVA joined the International Counsel for mines and metals (ICMM) in order to share a code of practice for a sustainable development. (A.C.)

Convincing about the advanced use of nuclear energy closing the fuel cycle: from a burden to a solution

International Nuclear Information System (INIS)

Neau, Henry Jacques

2007-01-01

France has associated a closed fuel cycle with its nuclear program, and developed the corresponding treatment recycling capabilities accordingly. This choice was recently consolidated by law. according to the sustainable management of radioactive materials and waste act of June 2006, the volume and radio toxicity reduction of nuclear waste is an objective that can notably be reached with their treatment and conditioning. Presently, used fuel valuable components (U and Pu) are recycled into MOX fuel and RepU, when fission products are conditioned under an extremely solid and resistant form which cannot disperse and dissolve in the environment (High Level Vitrified Waste). Safety and waste minimisation remain the AREVA constant objective. Presently operated treatment and recycling AREVA NC facilities are using mature industrial technologies, which address environment preservation and non proliferation concerns. This french national choice requires a permanent global acceptance strategy towards politicians, media, associations and more generally public opinion: to. be accepted, in needs to be understood. Transparency, dialogue and information are keywords for AREVA NC to be sure that closing the fuel cycle is considered as the best option available now for responsibly managing the waste, respecting the environment, preserving the resource and securing the future. Partnering in this Global Acceptance policy with other countries and customers, who already rely- or plan to do so - on this recycling strategy is both a reality and a permanent axis of development for AREVA NC

AREVA is convinced that HTR (High Temperature Reactor) is not in competition with large LWRs for electricity generation, and that its actual added value is its potential for addressing cogeneration and industrial process heat production. Therefore AREVA launched in 2004 the ANTARES programme for a pre-conceptual design study, with the support of EDF and together with a large research and development programme needed for the design in close collaboration with Cea. The pre-conceptual phase was finalized end of 2006. The specific feature of AREVA's concept, which distinguishes it from other ones, is its indirect cycle design powering a combined cycle power plant. Several reasons support this design choice, one of the most important being the design flexibility to adapt readily to combined heat and power applications, with a standardised nuclear heat source as independent as possible of the versatile process heat applications with which it is coupled. Standardisation should expedite licensing. In view of the volatility of the costs of fossil fuels, AREVA's choice brings to the large industrial heat applications the fuel cost predictability of nuclear fuel with the efficiency of a high temperature heat source free of greenhouse gases emissions. The reactor module produces 600 MWth which can be split into the required process heat, the remaining power driving an adapted prorated electric plant. Depending on the process heat temperature and power needs, up to 80 % of the nuclear heat is converted into useful energy

The aim of this protocol of agreement is to propose to wind turbine fitters some models of contracts allowing the setting up of wind turbines on agricultural lots. These documents, which make an indissociable ensemble, apply to both phases of development of a wind power project: the feasibility study phase, for a duration comprised between 2 and 5 years (studies, administrative procedures, precise definition of the project), and the construction, exploitation and dismantling phase. These documents will serve as common guidelines for both the farmers and the wind turbine designers. Both parties agree to meet together in the future to propose some modifications of these texts if necessary. The four models of contracts are attached to the document: contract for the feasibility study phase, first contract between the landlord and the farmer for the cancellation of the rural lease, second contract between the landlord and the wind power exploitation company for the common right lease, and the third contract between the farmer and the wind power company for the indemnification convention.

Energy Technology Data Exchange (ETDEWEB)

Gipe, P

2007-07-01

This book is a translation of the edition published in the USA under the title of ''wind power: renewable energy for home, farm and business''. In the wake of mass blackouts and energy crises, wind power remains a largely untapped resource of renewable energy. It is a booming worldwide industry whose technology, under the collective wing of aficionados like author Paul Gipe, is coming of age. Wind Power guides us through the emergent, sometimes daunting discourse on wind technology, giving frank explanations of how to use wind technology wisely and sound advice on how to avoid common mistakes. Since the mid-1970's, Paul Gipe has played a part in nearly every aspect of wind energy development from installing small turbines to promoting wind energy worldwide. As an American proponent of renewable energy, Gipe has earned the acclaim and respect of European energy specialists for years, but his arguments have often fallen on deaf ears at home. Today, the topic of wind power is cropping up everywhere from the beaches of Cape Cod to the Oregon-Washington border, and one wind turbine is capable of producing enough electricity per year to run 200 average American households. Now, Paul Gipe is back to shed light on this increasingly important energy source with a revised edition of Wind Power. Over the course of his career, Paul Gipe has been a proponent, participant, observer, and critic of the wind industry. His experience with wind has given rise to two previous books on the subject, Wind Energy Basics and Wind Power for Home and Business, which have sold over 50,000 copies. Wind Power for Home and Business has become a staple for both homeowners and professionals interested in the subject, and now, with energy prices soaring, interest in wind power is hitting an all-time high. With chapters on output and economics, Wind Power discloses how much you can expect from each method of wind technology, both in terms of energy and financial savings. The book updated models, graphics, and weighty appendixes make it an invaluable reference for everyone interested in the emerging trend of wind power and renewable energy. (author)

The uranium market is going to rebound: how to be prepared for it?

International Nuclear Information System (INIS)

Sozoniuk, V.; Lokhov, A.

2015-01-01

The current prices for uranium are 35 dollars on the spot market and 50 dollars on the long-term market, both prices are relatively low compared with prices of a few years ago. Because of the low demand and of a ever growing offer, the uranium market goes through a period of production over-capacity. AREVA like other mining companies have cancelled or postponed new projects and slow down other ones. It is known that uranium deposits that are now exploited will be depleted by 2050 with only a few exceptions and that most countries using nuclear energy will continue using it despite the Fukushima accident. It means that the uranium market will get a bull trend in a near future. As the third uranium producer worldwide AREVA continues prospecting in order to discover the new uranium resources that will feed the nuclear reactors beyond 2030. In order not to lose competencies during this period of lean cows in mining activities, AREVA has set up an intern mining college where staff can be trained and knowledge be maintained. (A.C.)

Although many used nuclear fuel types have already been recycled, recycling plants are generally optimized for Light Water Reactor (LWR) UO{sub x} fuel. Benefits of used fuel recycling are consequently restricted to those fuels, with only limited capacity for the others like LWR MOX, Fast Reactor (FR) MOX or Research and Test Reactor (RTR) fuel. In order to recycle diverse fuel types, an innovative and polyvalent shearing and dissolving cell is planned to be put in operation in about 10 years at AREVA's La Hague recycling plant. This installation, called TCP (French acronym for polyvalent fuel treatment) will benefit from AREVA's industrial feedback, while taking part in the next steps towards a fast reactor fuel cycle development using innovative treatment solutions. Feasibility studies and R/Development trials on dissolution and shearing are currently ongoing. This new installation will allow AREVA to propose new services to its customers, in particular in term of MOX fuel, Research Test Reactors fuel and Fast Reactor fuel treatment. (authors)

The French nuclear industry is made up of 2500 enterprises of any size from family businesses to large groups via medium-sized enterprises and start-ups. In order to face new projects and to ensure the continuity and preservation of technical know-how and to develop skills, nuclear industry as any high-tech industry invests a lot of money in training. In 2017 the needs of training for EDF, AREVA and CEA employees summed up to 370 million euros representing 4.5 millions hours of technical training. In CEA, EDF and AREVA, colleges of experts have been created. For instance the knowledge of EDF experts specialised in the design of the first generation of reactors is very useful to prepare the dismantling of these reactors. In CEA, an average of 15 years are necessary to train an expert and 4 levels of expertise have been defined. AREVA has implemented in its staff management a tool to detect the risk of losing a specific skill and to prevent this loss by a provisional policy of recruitment. (A.C.)

In 2010, AREVA's consolidated revenue rose 6.7% to 9.104 billion euros (+ 5.1% growth like-for-like) compared with 2009. The Mining-Front End Business Group and the Reactors and Services Business Group were the leading growth engines, with revenue growth of 6.7% and 8.9% respectively. Foreign exchange had a positive impact of 141 million euros and the scope of consolidation remained stable over the period. Fourth quarter 2010 revenue totaled 2.936 billion euros, an increase of 7.7% (+4.8% like-for-like) compared with the fourth quarter of 2009, due in particular to 18.1% growth in the Mining-Front End BG. Foreign exchange had an impact of 58 million euros over the period. The group's backlog came to 44.2 billion euros at December 31, 2010, up 2.0% in relation to December 31, 2009. The backlog grew in the Mining-Front End and Renewable Energies BGs. Installed Base Business operations held up well, replenishing the backlog for the Reactors and Services BG. The agreement with the Indian utility NPCIL concerning the construction of two EPR{sup TM} reactors and fuel cycle supply for 25 years was not recorded in the backlog at December 31, 2010. The change in the Back End BG's backlog reflects the implementation of contracts signed in previous years. Nearly one billion euros in letters of intent signed in 2010 with US utilities corresponding to pre-sold production from the future enrichment plant were not included in the Mining-Front End BG's backlog. The backlog of the Mining-Front End BG came to 28.902 billion euros at December 31, 2010, up 4% compared with the end of 2009. Contracts won in 2010 include: - the 10-year uranium supply contract with CGNPC for approximately 3.5 billion dollars; - several other multi-year contracts signed in the front end of the cycle with US and Asian utilities. For the full year of 2010, the Mining-Front End BG reported revenue of 3.704 billion euros, an increase of 6.7% on a reported basis and of 4.2% LFL. Foreign

The Mining-Front End Business Group and the Reactors and Services Business Group were the leading growth engines, with revenue growth of 6.7% and 8.9% respectively. Foreign exchange had a positive impact of 141 million euros and the scope of consolidation remained stable over the period. Fourth quarter 2010 revenue totaled 2.936 billion euros, an increase of 7.7% (+4.8% like-for-like) compared with the fourth quarter of 2009, due in particular to 18.1% growth in the Mining-Front End BG. Foreign exchange had an impact of 58 million euros over the period. The group's backlog came to 44.2 billion euros at December 31, 2010, up 2.0% in relation to December 31, 2009. The backlog grew in the Mining-Front End and Renewable Energies BGs. Installed Base Business operations held up well, replenishing the backlog for the Reactors and Services BG. The agreement with the Indian utility NPCIL concerning the construction of two EPR TM reactors and fuel cycle supply for 25 years was not recorded in the backlog at December 31, 2010. The change in the Back End BG's backlog reflects the implementation of contracts signed in previous years. Nearly one billion euros in letters of intent signed in 2010 with US utilities corresponding to pre-sold production from the future enrichment plant were not included in the Mining-Front End BG's backlog. The backlog of the Mining-Front End BG came to 28.902 billion euros at December 31, 2010, up 4% compared with the end of 2009. Contracts won in 2010 include: - the 10-year uranium supply contract with CGNPC for approximately 3.5 billion dollars; - several other multi-year contracts signed in the front end of the cycle with US and Asian utilities. For the full year of 2010, the Mining-Front End BG reported revenue of 3.704 billion euros, an increase of 6.7% on a reported basis and of 4.2% LFL. Foreign exchange had a positive

McClean Lake. Site Guide

International Nuclear Information System (INIS)

2016-09-01

Located over 700 kilometers northeast of Saskatoon, Areva's McClean Lake site is comprised of several uranium mines and one of the most technologically advanced uranium mills in the world - the only mill designed to process high-grade uranium ore without dilution. Areva has operated several open-pit uranium mines at the McClean Lake site, and is evaluating future mines at and near the site. The McClean Lake mill has recently undergone a multimillion-dollar upgrade and expansion, which has doubled its annual production capacity of uranium concentrate to 24 million pounds. It is the only facility in the world capable of processing high-grade uranium ore without diluting it. The mill processes the ore from the Cigar Lake mine, the world's second largest and highest-grade uranium mine. The McClean Lake site operates 365 days a year on a week-in/week-out rotation schedule for workers, over 50% of whom reside in northern Saskatchewan communities. Tailings are waste products resulting from milling uranium ore. This waste is made up of leach residue solids, waste solutions and chemical precipitates that are carefully engineered for long-term disposal. The TMF serves as the repository for all resulting tailings. This facility allows proper waste management, which minimizes potential adverse environmental effects. Mining projections indicate that the McClean Lake mill will produce tailings in excess of the existing capacity of the TMF. After evaluating a number of options, Areva has decided to pursue an expansion of this facility. Areva is developing the Surface Access Borehole Resource Extraction (SABRE) mining method, which uses a high-pressure water jet placed at the bottom of the drill hole to extract ore. Areva has conducted a series of tests with this method and is evaluating its potential for future mining operations. McClean Lake maintains its certification in ISO 14001 standards for environmental management and OHSAS 18001 standards for occupational health

Finnish EPR Olkiluoto 3. The world's first third-generation reactor now under construction

International Nuclear Information System (INIS)

2007-01-01

The EPR was developed by Framatome and Siemens KWU (the nuclear division of Siemens), whose nuclear activities were combined in January 2001 to form Framatome ANP, now AREVA NP. The French electricity utility EDF (Electricite de France), together with the major German utilities, played an active role in the project. The safety authorities of the two countries joined forces to bring their respective safety standards into line and draw up joint design rules for the new reactor. On December 18, 2003, the consortium formed by AREVA and Siemens - and led by AREVA - signed a contract with TVO for the turnkey construction of the EPR. The overall Olkiluoto 3 project cost has been estimated by TVO at around euros 3 Billion. TVO is responsible for the overall project management and licensing process with the Finnish Safety Authority STUK. In the pre-qualification phase, STUK concluded that the EPR can meet the Finnish licensing requirements. All specific comments will be taken into account for the realization of the project. In January 2005, STUK emphasized in its safety assessment that the evolutionary EPR design compared to predecessor product lines has been further enhanced by AREVA. This paper presents first, The Finnish energy situation (Electricity consumption and supply, Finland's Kyoto CO 2 cutback, Competitiveness of nuclear power), and then the EPR in Olkiluoto (General schedule of responsibilities, Important milestones of the project). Finally, the EPR third-generation and advanced reactor is presented with its position in the international competition (Targeted design objectives, Main characteristics, competitiveness, safety, Additional measures to prevent the occurrence of events likely to damage the core, Increased protection against the consequences of core melt)

Used Fuel Logistics: Decades of Experience with transportation and Interim storage solutions

Energy Technology Data Exchange (ETDEWEB)

Orban, G.; Shelton, C.

2015-07-01

Used fuel inventories are growing worldwide. While some countries have opted for a closed cycle with recycling, numerous countries must expand their interim storage solutions as implementation of permanent repositories is taking more time than foreseen. In both cases transportation capabilities will have to be developed. AREVA TN has an unparalleled expertise with transportation of used fuel. For more than 50 years AREVA TN has safely shipped more than 7,000 used fuel transport casks. The transportation model that was initially developed in the 1970s has been adapted and enhanced over the years to meet more restrictive regulatory requirements and evolving customer needs, and to address public concerns. The numerous “lessons learned” have offered data and guidance that have allowed for also efficient and consistent improvement over the decades. AREVA TN has also an extensive experience with interim dry storage solutions in many countries on-site but also is working with partners to developed consolidated interim storage facility. Both expertise with storage and transportation contribute to safe, secure and smooth continuity of the operations. This paper will describe decades of experience with a very successful transportation program as well as interim storage solutions. (Author)

International Nuclear Information System (INIS)

Sene, Monique; Sene, Raymond

2011-11-01

This document proposes an analysis of the reports made by the different operators of nuclear installations within the frame of a safety audit of the French nuclear installations with respect to the Fukushima accident. Operators (mainly AREVA, the CEA and EDF) were asked to perform additional safety assessments. In a first part, the conclusions of EDF reports are analysed regarding the seismic risk, the flooding risk, the situation of some specific sites (Fessenheim, Tricastin), other phenomena (rains, winds), loss of electricity supplies and of cooling systems, severe accidents, hydrogen issue, chemical hazards, subcontractors, crisis management. Conclusions of AREVA reports are analysed for the different sites (Tricastin, La Hague, MELOX factory, Romans factory). Conclusions of CEA reports are analysed for the different concerned installations (ATPu, Masurca, Osiris, Phenix, Jules Horowitz reactor). A second part proposes a global analysis of EDF's additional safety assessment reports regarding earthquake, flooding, other extreme natural phenomena, loss of electricity supplies and cooling system, subcontracting conditions, crisis management, and radiation protection organisation. AREVA's and CEA's reports are then analysed in terms of report structure and content, and for the different concerned sites

What is done in France to ensure that funds will be available when needed?

International Nuclear Information System (INIS)

Locufier, Arnaud; Javanni, Jean

2006-01-01

3 nuclear operators in France (EDF, AREVA, CEA) and a national agency for radioactive waste management (ANDRA). Supervision of the operators by the Government Departments and regulatory control of safety through the Nuclear Safety Authority (ASN). Funding: No legal requirements for the operators to create a specific fund for D and D and waste long term management. However, EDF, AREVA and CEA already set up funds with specific assets. These funds are managed by the companies, supervised by a special committee (CEA and AREVA) which play an advisory role for the Board of Directors. Evolutions: Open competition on European electricity market, evolution of EDF status, AREVA could go public, 2006 debate on HLW-LL long term management. It is essential to redefine the French approach. The time constant is quite long. A European frame could be used. France Favours a Harmonised European Legal Frame. France shared the intentions of Mrs. De Palacio in launching the 'Nuclear Package' (continuation to the Green Paper). France favoured the inclusion of the dismantling issue in this Package: Lack of provisions on this issue is a matter of concern, mandatory segregation of funds is not suitable for all MS, a balance had been found. But the Nuclear Package has not been voted: Council Conclusion of 28 June 2004. Member States to work together in a 'Bottom-Up' Approach. Commission issued its report 3 Nov. 2004. Pending legal issues: Legal base for European legislation: safety (Euratom) or competition law (EC)?; Where/which are State Aids that may distort competition? Support an 'Action Plan' for the implementation of the Conclusions of the Council (towards 2006-2007). France is committed to come to a European consensus on the implementation of the following: 'to ensure that adequate financial resources are available as to cover when needed the decommissioning costs'

2009-07-01

This document comments a specification submitted by AREVA for the vitrification of rinsing effluents produced by shutting-down operations of the UP2-400 plant. After a description of the context created by the dismantling of this plant (decontamination operations, project of packaging effluents in an alumino-borosilicate matrix, contaminated compounds), this report discusses the assessment of the 300 AQ 61 specification proposed by AREVA. The quality of the process is related to the incorporation and to the homogeneous distribution of the radioactive material in a vitreous network. The report comments the specification with respect to the content assessed values for the different compounds and species, and with respect to the vitrification process parameters

2014-01-01

This article comments the statement made by an EDF official before the inquiry commission of the French National Assembly, about the works initiated by EDF and Areva to improve the EPR profitability. This would lead to the design of a safer, more efficient and less costly new reactor which would however require a certification. This project is based on an optimization of the Areva's EPR, and would propose different power levels, notably less powerful reactors for less connected grids (for example in Saudi Arabia), and less powerful reactors would mean less expensive reactors. The article also evokes the issue of the cost of the Finnish EPR, and the different existing and projected EPR reactors

Change-management. From commercial power operation to post power operation and decommissioning

International Nuclear Information System (INIS)

Wasinger, Karl

2015-01-01

Transition from power generation to decommissioning challenges utilities. Power generation is mainly characterized by a stable working environment and constant workload, decommissioning and dismantling, however, by transformation and change. Also, changing requirements for the workforce's skills challenge the organization and its senior management. Ensuring effective and efficient performance, while maintaining motivation of staff, requires adjustment of management processes as well as of operational organization and human resources management. AREVA has more than 20 years of experience in decommissioning of own nuclear fuel cycle plants in France, as well as of other large plants and power reactors in Germany, the United Kingdom and the US. Therefore, the group has developed and successfully implemented integrated change management processes. The implementation of well-established and proven methods, developed by the productive industry and adjusted to the nuclear regulatory requirements, significantly improves the performance and efficiency of means and methods in use. The AREVA Performance Improvement Process defines concrete approaches to identify and improve potential deficits of productivity in six main areas (decommissioning scenarios and stra-tegies, waste treatment and logistics, operations management, supply chain, regulatory monitoring and controls as well as dismantling operation). Nuclear plant and facility owners around the world benefit from AREVA experts well experienced in execution of large and complex decommissioning projects.

Steam generator assessment for sustainable power plant operation

Drexler, Andreas; Fandrich, Joerg; Ramminger, Ute; Montaner-Garcia, Violeta

2012-09-01

Water and steam serve in the water-steam cycle as the energy transport and work media. These fluids shall not affect, through corrosion processes on the construction materials and their consequences, undisturbed plant operation. The main objectives of the steam water cycle chemistry consequently are: - The metal release rates of the structural materials shall be minimal - The probability of selective / localized forms of corrosion shall be minimal. - The deposition of corrosion products on heat transfer surfaces shall be minimized. - The formation of aggressive media, particularly local aggressive environments under deposits, shall be avoided. These objectives are especially important for the steam generators (SGs) because their condition is a key factor for plant performance, high plant availability, life time extension and is important to NPP safety. The major opponent to that is corrosion and fouling of the heating tubes. Effective ways of counteracting all degradation problems and thus of improving the SG performance are to keep SGs in clean conditions or if necessary to plan cleaning measures such as mechanical tube sheet lancing or chemical cleaning. Based on more than 40 years of experience in steam-water cycle water chemistry treatment AREVA developed an overall methodology assessing the steam generator cleanliness condition by evaluating all available operational and inspection data together. In order to gain a complete picture all relevant water chemistry data (e.g. corrosion product mass balances, impurity ingress), inspection data (e.g. visual inspections and tube sheet lancing results) and thermal performance data (e.g. heat transfer calculations) are evaluated, structured and indexed using the AREVA Fouling Index Tool Box. This Fouling Index Tool Box is more than a database or statistical approach for assessment of plant chemistry data. Furthermore the AREVA's approach combines manufacturer's experience with plant data and operates with an

A cohort of workers of Areva NC of Pierrelatte was constituted to study the effects of the internal irradiation after the incorporation of uranium. Between 1960 and 1996, this establishment provided the uranium hexafluoride enrichment and since 1982, the chemical conversion of the different compounds of yellow cake. The cohort descriptive and the results of mortality are reported. The cohort presents a a good follow up (zero lost sight people) of workers potentially exposed to uranium. Its mortality is similar to this one of other workers (at Areva NC). The effect of the sane worker is important, due essentially to the selection of workers at hiring. The employments-exposures matrix at Pierrelatte will allow to study the effects of exposure on the mortality by cancer. (N.C.)

The design of advanced Boiling Water Reactor (BWR) fuel assemblies and cores is governed by the basic requirement of safe, reliable and flexible reactor operation with optimal fuel utilization. AREVA NP's comprehensive steady state and transient BWR methodology allows the designer to respond quickly and effectively to customer needs. AREVA NP uses S-RELAP5/RAMONA as the appropriate methodology for the representation of the entire plant. The 3D neutron kinetics and thermal-hydraulics code has been developed for the prediction of system, fuel and core behavior and provides additional margins for normal operation and transients. Of major importance is the extensive validation of the methodology. The validation is based on measurements at AREVA NP's test facilities, and comparison of the predictions with a great wealth of measured data gathered from BWR plants during many years of operation. Three of the main fields of interest are stability analysis, operational transients and reactivity initiated accidents (RIAs). The introduced 3D methodology for operational transients shows significant margin regarding the operational limit of critical power ratio, which has been approved by the German licensing authority. Regarding BWR stability a large number of measurements at different plants under various conditions have been performed and successfully post-calculated with RAMONA. This is the basis of reliable pre-calculations of the locations of regional and core-wide stability boundaries. (authors)

Multi-project, multi-national, geographically dispersed: Challenges for the Nuclear Renaissance in the United States

International Nuclear Information System (INIS)

Mathews, T.A.

2007-01-01

The nuclear renaissance in the United States is moving at a rapid pace due to the incentives in the Energy Policy Act of 2005, recognition of the environmental benefits of nuclear energy, and the need for stable, reliable, and diverse sources of energy. The U.S. is looking externally to capitalize on French, German, Japanese, and other worldwide experience. A number of challenges to the resurgence of nuclear power are common worldwide, including project management, workforce and supplier availability and large-project construction management experience. For example, AREVA's new plant project teams are comprised of resources drawn from various U.S. centers of technical expertise and backed up by AREVA's worldwide capabilities. However, the challenge lies in having the information infrastructure in place to integrate that expertise and share information across working groups. In another example, the U.S. regulatory process has changed significantly for the better, but the new streamlined combined license process has not been tested. Reactor vendors and utilities have injected new thinking into the process by pursuing Design Certification, Early Site Permit, and Combined License approval in parallel rather than in series. This paper will discuss these and other challenges to licensing and building new nuclear plants, and the approaches being used by AREVA to lead the Nuclear Renaissance in the United States. (author)

AREVA's code development program was practically completed in 2014. The basic codes supporting a new generation of advanced methods are the followings. GALILEO is a state-of-the-art fuel rod performance code for PWR and BWR applications. Development is completed, implementation started in France and the U.S.A. ARCADIA-1 is a state-of-the-art neutronics/ thermal-hydraulics/ thermal-mechanics code system for PWR applications. Development is completed, implementation started in Europe and in the U.S.A. The system thermal-hydraulic codes S-RELAP5 and CATHARE-2 are not really new but still state-of-the-art in the domain. S-RELAP5 was completely restructured and re-coded such that its life cycle increases by further decades. CATHARE-2 will be replaced in the future by the new CATHARE-3. The new AREVA codes and methods are largely based on first principles modeling with an extremely broad international verification and validation data base. This enables AREVA and its customers to access more predictable licensing processes in a fast evolving regulatory environment (new safety criteria, requests for enlarged qualification databases, statistical applications, uncertainty propagation...). In this context, the advanced codes and methods and the associated verification and validation represent the key to avoiding penalties on products, on operational limits, or on methodologies themselves

After a first brief article about the difficult situation faced by Areva, and an article about the Japanese situation four years after the Fukushima accident and the progressive restarting of reactors, an article proposes an overview of recent evolutions and events in the energy sector: the sharp decrease of oil prices and its consequences for Total and the European Union. Three articles concern nuclear activities: recent events in the mining and fuel fabrication sectors (perspectives, restructuring in the USA, contracts for Areva and EDF), overview of the situation of reactors (with perspective for the installed power by 2050, unclear perspectives in France, projects in the UK in Hinkley Point, Moorside, and Wylfa, situation in Belgium, Hungary and Russia, contracts for Areva and EDF, situation in Taiwan, India, South Korea, Japan, USA, South Africa), overview of activities and events related to the back-end of the fuel cycle and to decommissioning in different countries (recycling activities in France, decommissioning in France and in the UK, warehousing in France and Germany, a new warehousing system to be approved in the USA, events related to storage activities). An article discusses issues related to the lifetime of French nuclear reactors, and another one discusses the identification of electric power costs and ways to compare them. A last article briefly discusses some terminological confusion between energy and electricity, and between produced energy and available power

AREVA has a unique experience in providing sustainable solutions for used fuel management, fitted with the needs of different customers in the world and with regulation in different countries. These solutions entail both recycling and interim storage technologies. In a first part, we will describe the various types of solutions for Interim Storage of UNF that have been implemented around the world for interim storage at reactor or centralized Pad solution in canisters dry storage, vault type storages for dry storage, dry storage of transportation casks (dual purpose) pools for wet storage, The experience for all these different families of interim storages in which AREVA is involved is extensive and will be discussed with respect to the new challenges: increase of the duration of the interim storage (long term interim storage) increase of burn up of the fuels In a second part of the presentation, special recycling features will be presented. In that case, interim storage of the used fuels is ensured in pools. This provides in the long term good conditions for the behaviour of the fuel and its retrievability. With recycling, the final waste (Universal Canister of vitrified fission products and compacted hulls and end pieces): is stable and licensed in many countries for the final disposal (France, UK, Belgium, NL, Switzerland, Germany, Japan, upcoming: Spain, Australia, Italy). Presents neither safety criticality risks nor proliferation risks (AREVA conditioned HLW and LL-ILW are free of IAEA safeguard constraints thanks to AREVA process high recovery and purification yields). It can therefore be safely stored in interim storage for more than 100 years before final disposal. Some economic considerations will also be discussed. In particular, in the case of long term interim storage of used fuels, there are growing uncertainties regarding the future needs of repackaging and transportation, which can result in future cost overruns. Meanwhile, in the recycling policy

Setting UP a decontamination and dismantling (D and D) scenario - methodology and tools developed leopard

At the AREVA NC La Hague site, the former nuclear spent fuel reprocessing plant UP2-400 was shutdown on December 30, 2003. Since then, the cleaning up and dismantling activities have been carried by the DV/PRO project, which is the program management organization settled by AREVA NC, for valorization projects. SGN, part of the AREVA NC Engineering Business Unit, operates as the main contractor of the DV/PRO project and provides project management services related to decommissioning and waste management. Hence, SGN is in charge of building D and D's scenarios for all the facilities of the UP2-400 plant, in compliance with safety, technical and financial requirements. Main outputs are logic diagrams, block flow diagrams, wastes and effluents throughputs. In order to meet with AREVA NC's requirements and expectations, SGN developed specific process and tools methods adapted to the scale and complexity of decommissioning a plant with several facilities, with different kind of processes (chemical, mechanical), some of which are in operation and other being dismantled. Considering the number of technical data and inputs to be managed, this methodology leads to complex outputs such as schedules, throughputs, work packages... The development, the maintenance and the modification of these outputs become more and more difficult with the complexity and the size of the plant considered. To cope with these issues, SGN CDE/DEM UP2-400 project team has developed a dedicated tool to assist and optimize in elaborating D and D scenarios. This tool is named LEOPARD (Logiciel d'Elaboration et d'Optimisation des Programmes d'Assainissement Radiologique et de Demantelement) (Software for the Development and Optimization of Radiological Clean up and Dismantling Programs). The availability of this tool allowed the rapid construction of a test case (demonstrator) that has convinced DV/PRO of its numerous advantages and of the future further development potentials.

Studies of nuclear workers make it possible to directly quantify the risks associated with ionizing radiation exposure at low doses and low dose rates. Studies of the CEA (Commissariat à l'Energie Atomique) and AREVA Nuclear Cycle (AREVA NC) cohort, currently the most informative such group in France, describe the long-term risk to nuclear workers associated with external exposure. Our aim is to assess the risk of mortality from solid cancers among CEA and AREVA NC nuclear workers and its association with external radiation exposure. Standardized mortality ratios (SMRs) were calculated and internal Poisson regressions were conducted, controlling for the main confounding factors [sex, attained age, calendar period, company and socioeconomic status (SES)]. During the period 1968-2004, there were 2,035 solid cancers among the 36,769 CEA-AREVA NC workers. Cumulative external radiation exposure was assessed for the period 1950-2004, and the mean cumulative dose was 12.1 mSv. Mortality rates for all causes and all solid cancers were both significantly lower in this cohort than in the general population. A significant excess of deaths from pleural cancer, not associated with cumulative external dose, was observed, probably due to past asbestos exposure. We observed a significant excess of melanoma, also unassociated with dose. Although cumulative external dose was not associated with mortality from all solid cancers, the central estimated excess relative risk (ERR) per Sv of 0.46 for solid cancer mortality was higher than the 0.26 calculated for male Hiroshima and Nagasaki A-bomb survivors 50 years or older and exposed at the age of 30 years or older. The modification of our results after stratification for SES demonstrates the importance of this characteristic in occupational studies, because it makes it possible to take class-based lifestyle differences into account, at least partly. These results show the great potential of a further joint international study of

Trekkopje Mine. Stakeholder Report 2012-2013

2014-01-01

This document is Areva Namibia's stakeholder report for 2012-2013. During this time the company successfully completed pilot testing at the MIDI site, produced 440 tons of uranium and gained valuable experience that will help it optimise the process in the MAXI phase. The uranium was exported for further processing into nuclear fuel at the converter facility in France and royalties were paid to the Namibian government. The last two years were challenging for the uranium industry. There is currently an over-supply of uranium on the world market, partly due to Japan's nuclear reactors being stopped, and the spot market price dropping below US$40 per pound of uranium oxide in mid-2013. This has severely affected new developments in Namibia which generally need higher prices of around US$60-80 per pound to be viable. Taking into account the current economic conditions and the substantial investments yet to be made at the Trekkopje MAXI plant, it was decided to put the project on hold. The Trekkopje project went into a 'Care and Maintenance' phase from 1 July 2013. The mine is merely in a holding phase with every intention to start up as soon as the economic conditions become more favourable. The company is actively supporting local economic development through the Erongo Development Foundation's SME micro-finance scheme. On 14 August 2013, Areva signed an initial water supply agreement with NamWater. This agreement is a prelude to a medium-term contract to distribute up to 10 million cubic meters per annum. Areva's Erongo Desalination Plant will contribute to water supply security and help preserve the water reserves of the Erongo region.

Nuclear cycle facilities, such as recycling plants, over the world differ in their design and operation history. Transferability of Learning From Experience (LFE), Best Practices and Decommissioning tools and techniques may not appear as relevant as it would be for a fleet of reactors. Moreover Regulatory, Economic and Social Drivers may differ from one country to another. Technical Drivers being comparable, AREVA and Sellafield Ltd (SL) have conducted various benchmarks and technical peer reviews to consider LFE from AREVA's Post-Operation Clean Out (POCO) and Decommissioning projects (such as UP2-400 on the La Hague site) and those performed for customers (such as CEA's UP1 on the Marcoule site). The intention is that Sellafield can benefit from AREVA experience and incorporate some recommendations in their own programmes. These reviews highlighted not only that investigation tools and methods as well as Decommissioning techniques are fully transferable, but also that strategic, technical and organizational key recommendations are applicable. 1. End-state definition (for each programme step) has a strong impact on POCO and Decommissioning scenarios. 2. A waste-driven strategy is essential for the overall programme cost and schedule management, and it avoids detrimental activities and short-term decisions made under pressure that may have negative impacts on the Programme. 3. Safety issues associated with POCO and decommissioning programmes are different from the commercial operations environment. 4. An extensive characterization plan (with physical and radiological surveys and active sampling) is essential to underpin the final POCO / decommissioning scenario and build a plant configuration baseline that will be updated as the decommissioning progresses. 5. Transition from operations to decommissioning requires a major change in culture; the organization must adapt to the new decommissioning environment. 6. Securing specific competencies, resources and

A Prototype {sup 212}Pb Medical Dose Calibrator for Alpha Radioimmunotherapy

AREVA Med, an AREVA group subsidiary, is developing innovative cancer-fighting therapies involving the use of {sup 212}Pb for alpha radioimmunotherapy. Canberra Industries, the nuclear measurement subsidiary of AREVA, has been working with AREVA Med to develop a prototype measurement system to assay syringes containing a {sup 212}Pb solution following production by an elution system. The relative fraction of emitted radiation from the source associated directly with the {sup 212}Pb remains dynamic for approximately 6 hours after the parent is chemically purified. A significant challenge for this measurement application is that the short half-life of the parent nuclide requires assay prior to reaching equilibrium with progeny nuclides. A gross counting detector was developed to minimize system costs and meet the large dynamic range of source activities. Prior to equilibrium, a gross counting system must include the period since the {sup 212}Pb was pure to calculate the count rate attributable to the parent rather than the progeny. The dynamic state is determined by solving the set of differential equations, or Bateman equations, describing the source decay behavior while also applying the component measurement efficiencies for each nuclide. The efficiencies were initially estimated using mathematical modeling (MCNP) but were then benchmarked with source measurements. The goal accuracy of the system was required to be within 5%. Independent measurements of the source using a high resolution spectroscopic detector have shown good agreement with the prototype system results. The prototype design was driven by cost, compactness and simplicity. The detector development costs were minimized by using existing electronics and firmware with a Geiger-Mueller tube derived from Canberra's EcoGamma environmental monitoring product. The acquisition electronics, communications and interface were controlled using Python with the EcoGamma software development kit on a Raspberry

Nuclear Company AREVA is proud to look back on versatile experience in successfully dismantling nuclear components. After performing several minor dismantling projects and studies for nuclear power plants, AREVA completed the order for dismantling of all remaining Reactor Pressure Vessel internals at German Boiling Water Reactor Wuergassen NPP in October '08. During the onsite activities about 121 tons of steel were successfully cut and packed under water into 200l- drums, as the dismantling was performed partly in situ and partly in an underwater working tank. AREVA deployed a variety of different cutting techniques such as band sawing, milling, nibbling, compass sawing and water jet cutting throughout this project. After successfully finishing this task, AREVA dismantled the cylindrical part of the Wuergassen Pressure Vessel. During this project approximately 320 tons of steel were cut and packaged for final disposal, as dismantling was mainly performed by on air use of water jet cutting with vacuum suction of abrasive and kerfs material. The main clue during this assignment was the logistic challenge to handle and convey cut pieces from the pressure vessel to the packing area. For this, an elevator was installed to transport cut segments into the turbine hall, where a special housing was built for final storage conditioning. At the beginning of 2007, another complex dismantling project of great importance was acquired by AREVA. The contract included dismantling and conditioning for final storage of the complete RPV Internals of the German Pressurized Water Reactor Stade NPP. Very similar cutting techniques turned out to be the proper policy to cope this task. On-site activities took place in up to 5 separate working areas including areas for post segmentation and packaging to perform optimized parallel activities. All together about 85 tons of Core Internals were successfully dismantled at Stade NPP until September '09. To accomplish the best possible on

This article notably refers to, quotes and comments a hearing organised by the French Public Office for the Assessment Scientific and Technological Choices (OPECST) on the issue of safety of pressurized equipment in nuclear reactors, and which gathered the main concerned actors (Areva, EDF, IRSN, ASN) to have an overview of quality controls in AREVA NP fabrication plants. Two different issues have been addressed: a technical metallurgical issue related to some boiler-making parts, and an issue related to quality assurance. These issues concern different older reactors (Fessenheim for example) as well as new ones (EPR Flamanville). The article indicates the different measures planned, envisaged or already implemented by the concerned actors in order to improve knowledge in the boiler-making industry, and to ensure a better quality

In this paper a radioecological model (TOCATTA) for tritium transfer in a grassland ecosystem developed on an hourly time-step basis is proposed and compared with the first data set obtained in the vicinity of the AREVA-NC reprocessing plant of La Hague (France). The TOCATTA model aims at simulating dynamics of tritium transfer in agricultural soil and plant ecosystems exposed to time-varying HTO concentrations in air water vapour and possibly in irrigation and rain water. In the present study, gaseous releases of tritium from the AREVA NC nuclear reprocessing plant in normal operation can be intense and intermittent over a period of less than 24 hours. A first comparison of the model predictions with the field data has shown that TOCATTA should be improved in terms of kinetics of tritium transfer.

In Europe, MOX fuel has been supplied by AREVA for more than 30 years, to 36 reactors: 21 in France, 10 in Germany, 3 in Switzerland, 2 in Belgium. For the present and future, recycling is compulsory in the frame of sustainable development of nuclear energy. By 2030 the overall volume of used fuel will reach about 400 000 t worldwide. Their plutonium and uranium content represents a huge resource of energy to recycle. That is the reason why, the European Utilities issued an EUR (European Utilities Requirement) demanding new builds reactors to be able of using MOX Fuel Assemblies in up to 50 % of the core. AREVA GEN3+ reactors, like EPR TM or ATMEA TM designed with MHI partnership, are designed to answer any utility need of MOX recycling. The example of the EPR TM reactor operated with 100 % MOX core optimized for MOX recycling will be presented. A standard EPR TM can be operated with 100 % MOX core using an advanced homogeneous MOX (single Pu content) with highly improved performances (burn-up and Cycle length). The adaptations needed and the main operating and safety reactor features will be presented. AREVA offers the utilities throughout the world, fuel supply (UO 2 , ERU, MOX), and reactors designed with all the needed capability for recycling. For each country and each utility, an adapted global solution, competitive and non proliferant can be proposed. (authors)

2012-01-01

As the nuclear industry continues to grow throughout the world, we find that support from government officials, local business leaders and the general public is becoming more and more important. In order to help raise awareness and inform these various publics, AREVA expanded upon a best practice from its worldwide operations and recently established a Community Advisory Council in the United States. The member organizations represent a variety of grassroots and minority organizations from across the United States and are active in various ways in local, state and federal arenas. AREVA's objective for the Council is simple - listen to concerns, engage in dialogue and raise awareness about the intrinsic link existing between energy, CO 2 emissions, global warming, and economic growth, so these same people can make decisions when it comes to energy sources in the future. We want our members to help us better understand their communities, listen to their concerns and answer their questions openly and honestly. AREVA understands that this outreach and education are just the first steps toward helping clean energy sources grow. We must maintain regular dialog and operate in a safe manner, because in the long run, it is these community members who will ensure energy security for the country. And it is only by working together as an industry that we can ensure a safe, clean air future for generations to come, no matter where in the world we live. (authors)

2007-01-01

On June 29, 2006, the Radiochemical Laboratory of AREVA NP GmbH (formerly Siemens AG) in Erlangen celebrated its fiftieth anniversary. The occasion was marked by an event attended by more than 1,000 guests, among them Werner Gebauhr, the 85-year-old founder and first head of the Laboratory; the Managing Directors of AREVA NP GmbH, Ralf Gueldner and Ruediger Steuerlein; representatives of universities, research institutions, power utilities, and public authorities. The present head of the Radiochemical Laboratory, Wilfred Morell, sketched the highlights of the work performed over the past fifty years, which ranged from solid-state and very-high-purity materials technologies to development and service activities for nuclear technology. Manfred Erve, head of the Technical Center of AREVA NP GmbH, of which the Radiochemical Laboratory is a part, emphasized the changes in priorities over the past fifty years, which had always been met successfully by Radiochemistry. In the scientific part of the event, Wolfgang Schwarz (E.ON Kernkraftwerk GmbH, KKW Isar), Ulf Ilg (EnBW Kraftwerk AG, KKW Philippsburg), and Hans-Josef Allelein (Gesellschaft fuer Anlagen- und Reaktorsicherheit mbH) explained 3 major subject areas in which Erlangen Radio-chemistry over many years has contributed basic findings (see other articles in this atw issue). On the occasion of the anniversary, a comprehensive booklet was published under the title of '50 Jahre Radiochemie Erlangen - 1956-2006'. (orig.)

Uranium mines and French mining companies: a magnificent adventure

International Nuclear Information System (INIS)

Blanc, J.

2008-01-01

The French mining adventure still arouses enthusiasm. The search for uranium began in 1945 with the creation of the Cea (Atomic Energy Board) whose one mission was to supply the nascent French nuclear programme with the necessary materials. Prospecting works were then led throughout France, Madagascar, the Ivory Coast and the French equatorial Africa. More than 60 years later the only surviving actor of this quest for uranium has become the mining department of Areva Nuclear Cycle which is itself a sub-company of Areva. The author, who was an ancient high executive of Cogema draws a detailed history of the French uranium mining industry with with its ups and downs, by analysing the impact of the 2 oil crisis and of the decline of nuclear energy in the decade following the Chernobyl accident.

AREVA participates actively in networks of industry and science via university cooperation and gives new ideas born from practical experience for the academic training of future nuclear engineers. Thus, the company ensures both the availability of new talents for its export strategy and relevant expertise for nuclear safety in Germany. When it comes to education and science after the German nuclear phase-out decision, the efforts must focus on internationalization. Greater integration in international networks can contribute to keeping the nuclear know-how in Germany alive. This concerns both industry and science. By having foreign experts use German training facilities, participate in research projects and gather professional practice, they contribute to the safe operation here and experience first-hand our safety culture grown over decades. In this context, AREVA outlines its university cooperation in Germany and abroad.

The plate type IHX is the most challenging component for ANTARES due to the high temperature of helium at the core outlet (from 850 deg. C to 1000 deg. C). It is indeed a first of the kind as there is no past experience in nuclear or outside nuclear industries of such a component. It requires high performance materials and high technology manufacturing processes. It is also a key component regarding the efficiency and competitiveness of the plant. Then, an intensive work program was launched in AREVA NP in order to develop this component. Different units of AREVA NP and external organisations (R and D and industrials) are involved in this development. Collaboration agreements defining the framework and the rights of each partner were elaborated when necessary. Several potential technologies are investigated in parallel with the objective to select the best one before the end of 2008. This selection will be based on design studies, cost assessment, risk assessment and technological assessment including the realisation and tests of representative mock ups. These technologies are: - Plate Machined Heat Exchanger (PMHE) with CEA and EDF; - Plate Fin Heat Exchanger (PFHE) with industrials like Nordon, Brayton Energy; - Tubular concept. Plate type IHX, which is more compact but more challenging, is the reference concept for the conceptual design phase of ANTARES but tubular concept is also investigated as a fall back solution. It must be also noted that generic R and D on high temperature materials is in progress. It includes in particular creep, corrosion and nitriding tests on samples. Two alloys were selected (230 and 617) and the final selection of one alloy is planned for the end of 2006. PMHE is one of the most promising technologies. The plates are machined by high speed machining or electro chemical etching. First machining tests performed by the AREVA NP technical centre in Chalon are encouraging but the geometry of the drills still have to be optimised in order

From a nuclear materials management standpoint, spent-fuel recycling is considered a very challenging activity. This challenge has its positive counterpart as a lot has been learned from confronting a large variety of nuclear materials, complex material transfers and transformations. Since the inception of its computerized nuclear materials management system, AREVA NC La Hague has relied upon its IT subsidiary EURIWARE for software design and development. In 2003, the founding milestone was the implementation of the new GMP software package (Gestion des Matieres et des Produits - Materials and Products Management). GMP was underpinned by the following principles: reliability, transparency and close integration with the process control layer, so as to mitigate human errors and keep the management process smooth and efficient. In 2005, another major milestone was reached with CMNR (Comptabilite des Matieres Nucleaires Reglementaire - Regulatory Nuclear Materials Accountancy), a system in charge of local accounting and multi-site consolidation at corporate level. In spite of an auspicious start, GMP came up against the same stumbling block as many information systems: the multiplication of interfaces and technologies (entropy increasing over time). For the sake of maintenance, evolutions and performance, AREVA has decided a progressive modernization of its Nuclear Materials Management (NMM) information system. The underlying principle is a clear separation between the main functions: - Physical Follow-up, performed at the plant-level, - Regulatory Accountancy (for IRSN, EURATOM and IAEA safeguards), offering consolidation at the corporate level, - Patrimonial Accountancy (allocation of materials and conditioned wastes to AREVA's customers). The pivotal piece of this multi-year programme is the implementation of a dedicated data repository. We describe its main building blocks and demonstrate how it helps in managing changes to regulation, products, customers and

Highlights: • An overview of AREVA’s safety analysis codes their coupling is provided. • The validation base and licensing applications of these codes are summarized. • Coupled codes and methods provide improved margins and non-conservative results. • Examples for REA and inadvertent opening of the pressurizer safety valve are given. - Abstract: The main focus of safety analysis is to demonstrate the required safety level of the reactor core. Because of the demanding requirements, the quality of the safety analysis strongly affects the confidence in the operational safety of a reactor. To ensure the highest quality, it is essential that the methodology consists of appropriate analysis tools, an extensive validation base, and last but not least highly educated engineers applying the methodology. The sophisticated 3-dimensional core models applied by AREVA ensure that all physical effects relevant for safety are treated and the results are reliable and conservative. Presently AREVA employs SCIENCE, CASMO/NEMO and CASCADE-3D for pressurized water reactors. These codes are currently being consolidated into the next generation 3D code system ARCADIA®. AREVA continuously extends the validation base, including measurement campaigns in test facilities and comparisons of the predictions of steady state and transient measured data gathered from plants during many years of operation. Thus, the core models provide reliable and comprehensive results for a wide range of applications. For the application of these powerful tools, AREVA is taking benefit of its interdisciplinary know-how and international teamwork. Experienced engineers of different technical backgrounds are working together to ensure an appropriate interpretation of the calculation results, uncertainty analysis, along with continuously maintaining and enhancing the quality of the analysis methodologies. In this paper, an overview of AREVA’s broad application experience as well as the broad validation
