The panorama of research reactors in the world is at a turning point, with many old ones being shutdown, a very few new ones under construction and many newcomer countries interested to get access to one or to build one domestic research reactor or zero-power reactor. In this evolving context, several actions have been set up to answer this international collaboration need: the IAEA has launched the ICERR initiative, the OECD/NEA is proposing the P2M joint project proposal. In France, the Jules Horowitz Reactor (JHR), under construction at CEA Cadarache, within an International Consortium, will be one of the few tools available for the industry and research in the next decades. The paper presents some update of its construction, its experimental capacities and the European support through FP7 and H2020 tools. This paper provides also some insights of international tools (ICERR, P2M) and about the International Group on Research Reactors (IGORR) and how they complement or interact with the JHR.

The rotary inertia of the reactor’s primary pump is an important factor related to the reactor’s safety under some accidental conditions. If the rotary inertia of the primary pump is big, that the pump’s inertia time will be long and the coolant mass flow rate will decrease slowly. So it is helpful to remove the residual heat and enhance the safety of the reactor. On the other hand, a bigger rotary inertia increases the cost, and causes some other inconvenience. In this paper, our research object is China Advanced Research Reactor (CARR) which is under construction. Systemic mathematical and physical models were set up and a program was developed using FORTRAN language with GEAR numerical method to analyze the transient of CARR. The primary thermal-hydraulic parameters of the reactor core were obtained in case of loss of power accident under different rotary inertia of the pump. These parameters include the temperature of the coolant the clad and the fuel, the maximal quality of the reactor core and MDNBR, etc. On the basis of the calculate result, it can be found that when the rotary inertia of the pump is larger than 150 Kg·m2, all of the thermal parameters in loss of power accident meet the safety requirement. And if the rotary inertia of the pump is 450 Kg·m2 which is the design value of CARR, the delay shutdown time in loss of power accident must not exceed 20 seconds.

In 2012, AFCEN (Association Française pour les règles de Conception et de Construction des Matériels des Chaudières Electro-nucléaires) will publish the fifth edition of the RCC-MR code, named RCC-MRx 2012. This RCC-MRx Code is the result of the merger of the RCC-MX 2008 developed in the context of the research reactor Jules Horowitz Reactor project, in the RCC-MR 2007 which set up rules applicable to the design of components operating at high temperature and to the Vacuum Vessel of ITER. RCC-MRx, developed especially for Sodium Fast Reactors (SFR), Research Reactors (RR) and Fusion Reactors (FR-ITER) can also be used for components of other types of nuclear facilities (except PWR). It has been consider for instance in the frame of the CEN-Workshop (CEN-WS-MRx) in order to develop, on its basis, the European code for the design and fabrication of mechanical equipments for ESNII innovative nuclear installations. The main objective of the RCC-MRx is to capitalize the technical feedback of projects such as SUPERPHENIX, JHR, but also to meet the needs of MYRRHA, PFBR and ASTRID projects and to prepare the design and construction of ALFRED and ALLEGRO. This paper presents the technical evolutions in the 2012 edition and the AFCEN organization dedicated to work in an international frame.

The last decade has seen the emergence and growth in this country, and elsewhere, of science parks. In 1984 the United Kingdom Science Park Association (UKSPA) was set up with eight founder members. The mushrooming that followed meant that by 1986 the Association could report 28 fully operated parks, seven others under construction and a number of Associate Members, of which Reading University was one.

The 2015 presidential election was a turning point in a history of celebritisation of politics in Poland. Rock vocalist Paweł Kukiz unexpectedly finished third with 20% of votes, the highest result of any celebrity–candidate in presidential elections. He achieved that, campaigning mostly on Facebook, without any significant power base and financial support. Kukiz set up his own political organisation, which gained a 9% backing in the parliamentary elections. He achieved that with no political platform, no media backing, and no party structure. We argue that his persona was a crucial asset in his political success. We will show how Kukiz created, managed and performed his persona, how he used it to mobilise three million voters and then to create and brand his “Kukiz’15 Movement.” Finally, we analyse limits, traps and contradictions of persona power. Analysed material includes Paweł Kukiz’s and his opponents’ Facebook posts, televised political advertisements, performances in celebrity TV shows and debates.

In recent years, various national medical databases have been set up in the EU from disparate local databases and file systems. Medical records contain personal data and are as such protected by EU and member states’ legislation. Medical data, in addition to being personal data, is also defined in the EU legislation as being especially sensitive and warrants special measures to protect it. It therefore follows that various legal issues and concerns arise in connection with these processes. Such issues relate to the merits of compiling a nationwide database, deciding on who has access to such a database, legitimate uses of medical data held, protection of medical data, and subject access rights amongst others. This chapter examines some of these issues and argues that such databases are inevitable due to technological change; however there are major legal and information security caveats that have to be addressed. Many of these caveats have not yet been resolved satisfactorily, hence making medical databases that already exist problematic.

Within the Euratom research and training program 2014–2018, three projects aiming at securing the fuel supply for European power and research reactors have been funded. Those three projects address the potential weaknesses – supplier diversity, provision of enriched fissile material – associated with the furbishing of nuclear fuels. First, the ESSANUF project, now terminated, resulted in the design and licensing of a fuel element for VVER-440 nuclear power plant manufactured by Westinghouse. The HERACLES-CP project aimed at preparing the conversion of high performance research reactor to low enriched uranium fuels by exploring fuels based on uranium-molybdenium. Finally, the LEU-FOREvER pursues the work initiated in HERACLES-CP, completing it by an exploration of the high-density silicide fuels, and including the diversification of fuel supplier for soviet designed European medium power research reactor. This paper describes the projects goals, structure and their achievements.

A draft of the fifth edition of the RCC-MR code, named RCC-MRx 2010, has been issued in French and English versions on December 2010 by AFCEN (Association Franc¸aise pour les re`gles de Conception et de Construction des Mate´riels des Chaudie`res Electro-nucle´aires). This RCC-MRx Code is the result of the merger of the RCC-MX 2008 developed in the context of the research reactor Jules Horowitz Reactor project, in the RCC-MR 2007 which set up rules applicable to the design of components operating at high temperature and to the Vacuum Vessel of ITER. This is a non-public document established in order to prepare the fifth edition which will be published in French and English by AFCEN and will be named RCC-MRx 2012. By this next edition, AFCEN try to bring together all the relevant stakeholders in a CEN-Workshop (CEN-WS-MRx) in order to develop, on the RCC-MRx basis, the European code for the design and fabrication of mechanical equipments for ESNII innovative nuclear installations. This CEN Workshop (whose duration is 18 months, from January 2011) will allow the Workshop members to consider the RCC-MRx 2010 and to propose modifications to be included in the RCC-MRx 2012 edition to meet the needs of MYRRHA and ASTRID projects and to prepare the design and construction of ALFRED and ALLEGRO. This paper presents the code evolutions from the 2007 edition of the RCC-MR and describes the organization of the Workshop.

The present paper exposes the current research work carried out at LABORATOIRE DE THERMOCINE´TIQUE de NANTES within the framework of a collaborative research with DCN PROPULSION concerning the design of nuclear structures subjected to dynamic loading. The case under study consists of a cylinder strongly accelerated from rest in an infinite fluid medium. The main aim of the study is to predict forces acting on the cylinder and to provide a clear description of the flow phenomena. The duration of the mechanical impulse imposed on the cylinder is extremely short (of the order 15 milliseconds). The level of acceleration is 30 times the gravitational acceleration. These operating conditions are representative of a typical shock encountered in the environment of a military ship. This work is composed of a numerical and an experimental part. The numerical modeling is developed in a finite volume formulation. The cylinder is moved inside the computational domain using the ALE formulation for the moving mesh grid. Well-documented experiments on a cylinder impulsively started from rest are simulated to test the numerical procedure and validate our code. Then shocks with sinusoidal acceleration are simulated and compared with the theoretical model of Stokes. The experimental part presents the set-up currently under construction in the laboratory. The cylinder is put in motion by a hydraulic accelerator connected to a power hydraulic station and driven by a computer-controlled servo-valve. The metallic bar holding the cylinder is equipped with strain gauges measuring the integral forces acting on the cylinder.

The 2015 edition of the RCC-MRx Code will be issued, by the end of the year, in French and English versions by AFCEN (Association Française pour les règles de Conception et de Construction des Matériels des Chaudières Electro-nucléaires). This Code set up rules applicable to research reactor components (coming from the RCC-MX 2008 developed in the context of the Jules Horowitz Reactor project), and to components operating at high temperature and to the Vacuum Vessel of ITER (coming from the RCC-MR 2007). A significant work has been performed since 2012, first edition of the RCC-MRx, in order to improve the rules, to facilitate its use and understandability, and also to have a better fit with the feedbacks of the main projects (ASTRID, JHR, ITER). This paper presents the technical evolutions in the 2015 edition and also the other initiatives led upstream (prenormative works) and downstream (publication of the rules background - criteria) of the publication of rules.
