  1. Hoshin Kanri. Principle Centered Leadership

    Villalba-Díez, Javier
    The purpose of this paper is to sketch the outlines of what will, hopefully become my PhD thesis: the proposal of an evolutional leadership behavioral pattern, Hoshin Kanri, that enables process owners in organizations attain alignment by achieving their goals while increasing trust. ! I intend to develop such a behavioral pattern or “proper way” 善道 1 by adopting a network perspective over two organizational dimensions: process dimension and process owner dimension. In both dimensions I will propose measures of their topological structure and functionality. From there I will propose quantifiable characteristics that will help me enunciate several hypothesis about their dynamical and...

    Vedrenne, Michel; Borge García, Rafael; Lumbreras Martin, Julio; Andrés Almeida, Juan Manuel de; Rodríguez Hurtado, María Encarnación; Paz Martín, David de la; Pérez Rodríguez, Javier; Karanasiou, Angeliki; Moreno, Teresa; Boldo, E.; Linares, C.
    The need for a better quantification of the influence of Saharan dust transport processes on the air quality modelling in the Mediterranean basin led to the formulation of a dust emission module (DEM) integrated into the Air Quality Risk Assessment System for the Iberian Peninsula (SERCA). This paper is focused on the formulation of DEM based on the GOCART aerosol model, along with its integration and execution into the air quality model. It also addresses the testing of the module and its evaluation by contrasting results against satellite products such as MODIS and CALIPSO and ground-level observations of aerosol optical...

  3. Consequences of different meteorological scenarios in the environmental impact assessment of tritium in air

    Castro, P.; Velarde Mayol, Marta; Ardao, Jose; Perlado Martín, José Manuel; Sedano, Luis
    The environmental impact of systems managing large (kg) tritium amount represents a public scrutiny issue for the next coming fusion facilities as ITER and DEMO. Furthermore, potentially new dose limits imposed by international regulations (ICRP) shall impact next coming devices designs and the overall costs of fusion technology deployment. Refined environmental tritium dose impact assessment schemes are then overwhelming. Detailed assessments can be procured from the knowledge of the real boundary conditions of the primary tritium discharge phase into atmosphere (low levels) and into soils. Lagrangian dispersion models using real-time meteorological and topographic data provide a strong refinement. Advance simulation...

  4. Validation of real time dispersion of Tritium clouds over the Western Mediterranean Basin in different assesments

    Castro, P.; Velarde Mayol, Marta; Ardao, Jose; Perlado Martín, José Manuel; Sedano, L.
    Real time Tritium concentrations in air coming from an ITER-like reactor as source were coupled the European Centre Medium Range Weather Forecast (ECMWF) numerical model with the lagrangian atmospheric dispersion model FLEXPART. This tool ECMWF/FLEXPART was analyzed in normal operating conditions in the Western Mediterranean Basin during 45 days at summer 2010. From comparison with NORMTRI plumes over Western Mediterranean Basin the real time results have demonstrated an overestimation of the corresponding climatologically sequence Tritium concentrations in air outputs, at several distances from the reactor. For these purpose two clouds development patterns were established. The first one was following a...

  5. Differences into HT and HTO concentrations in air into the Western Mediterranean Basin and Continental Europe and Safety Related Issues.

    Castro, P.; Velarde Mayol, Marta; Ardao, Jose; Perlado Martín, José Manuel; Sedano, L.
    Real time Tritium concentrations in air in two chemical forms, HT and HTO, coming from an ITER-like fusion reactor as source were coupled the European Centre Medium Range Weather Forecast (ECMWF) numerical model with the Lagrangian Atmospheric-particle dispersion model FLEXPART. This tool was analyzed in nominal tritium discharge operational reference and selected incidental conditions affecting the Western Mediterranean Basin during 45 days during summer 2010 together with surface “wind observations” or weather data based in real hourly observations of wind direction and velocity providing a real approximation of the tritium behavior after the release to the atmosphere from a fusion...

A large work has been developed in different areas to arrive to a design of repetitive operation of Laser Fusion Reactor, and decisions are envisioned in the next phase of Technology Development or Risk Reduction for Engineering or Power Plant facilities (or both). Chamber design has...

  7. High Performance Algorithms and Implementations Using Sparse and Parallelization Techniques on MBS

    Hidalgo, Andrés Francisco; García de Jalón de la Fuente, Francisco Javier; Tapia Fernández, Santiago
    In this paper we will see how the efficiency of the MBS simulations can be improved in two different ways, by considering both an explicit and implicit semi-recursive formulation. The explicit method is based on a double velocity transformation that involves the solution of a redundant but compatible system of equations. The high computational cost of this operation has been drastically reduced by taking into account the sparsity pattern of the system. Regarding this, the goal of this method is the introduction of MA48, a high performance mathematical library provided by Harwell Subroutine Library. The second method proposed in this...

  8. Studies of a Self Cooled Lead Lithium blanket for HiPER Reactor

    Juarez Mañas, Rafael; Sanz Gonzalo, Javier; Sánchez, C.; Zanzi, C.; Hernández, J.; Perlado Martín, José Manuel
    Within the frame of the HiPER reactor, we propose and study a Self Cooled Lead Lithium blanket with two different cooling arrangements of the system First Wall – Blanket for the HiPER reactor: Integrated First Wall Blanket and Separated First Wall Blanket. We compare the two arrangements in terms of power cycle efficiency, operation flexibility in out-off-normal situations and proper cooling and acceptable corrosion. The Separated First Wall Blanket arrangement is superior in all of them, and it is selected as the advantageous proposal for the HiPER reactor blanket. However, it still has to be improved from the standpoint of...

  10. Li & Pb MD Sinulations

    Fraile García, Alberto; Cuesta Lopez, Santiago; Perlado Martín, José Manuel; Caro, Alfredo
    Pb17Li is today a reference breeder material in diverse fusion R&D programs worldwide. Extracting dynamic and structural properties of liquid LiPb mixtures via molecular dynamics simulations, represent a crucial step for multiscale modeling efforts in order to understand the suitability of this compound for future Nuclear Fusion technologies. At present a Li-Pb cross potential is not available in the literature. Here we present our first results on the validation of two semi-empirical potentials for Li and Pb in liquid phase. Our results represent the establishment of a solid base as a previous but crucial step to implement a LiPb cross...

  11. Influence of termal fluctuations in radiation damage cascade production and defect dynamics in tungsten

    Courtin, Sergio; Cuesta Lopez, Santiago; Perlado Martín, José Manuel
    The detailed study of the deterioration suffered by the materials of the components of a nuclear facility, in particular those forming part of the reactor core, is a topic of great interest which importance derives in large technological and economic implications. Since changes in the atomic-structural properties of relevant components pose a risk to the smooth operation with clear consequences for security and life of the plant, controlling these factors is essential in any development of engineering design and implementation. In recent times, tungsten has been proposed as a structural material based on its good resistance to radiation, but still...

  13. Waste Management Assessment of Candidate Materials for HiPER Reaction Chamber

    Sanz Gonzalo, Javier; Juarez Mañas, Rafael; Ognissanto, Flora; Perlado Martín, José Manuel
    One of the critical decisions in the HiPER project is to select the most appropriate material for the reaction chamber. Within this framework, we investigate the performance of different steel alloys with respect to waste management. The capabilities of commercial steels, both austenitic and ferritic/martensitic, compared to reduced-activation ferritic/martensitic steels are evaluated as for different waste management strategies (near surface burial, clearance, hands-on and remote recycling). The examined materials are: SS304, SS316, mod.9Cr-1Mo and HT9 and EUROFER. Real impurities concentrations are taken into account, and their impact is analyzed. In the study, we have assumed the most exigent HiPER 4a...

  14. Ess target performance for different beam pulses

    Sordo Balbín, Fernando; Domingo Lozano, Salvador; Perlado Martín, José Manuel; Sard, I.; Fernandez, A.; Bilbao, A.; Zarraoa Garmendia, A.; Gallmeier, F.X.; Ferguson, P.D.
    Last trends in the design of linear accelerators for high power spallation sources point to the use of ion beams of larger energies and shorter pulse lengths in order to enhance the reliability of the system. In this sense the recommendations for ESS are to increase the energy of the proton beam from 1.3GeV to 2-2.5GeV and to reduce the length of the beam pulse from 2ms to 1-1.5ms, keeping the source average power at 5MW. Different values for the repetition rate are also being discussed (16 2/3, 20, 25 Hz). ESS Bilbao is analyzing the impact of these modifications...

  15. Dose rates evaluation of HiPER facility

    Juarez Mañas, Rafael; Sanz Gonzalo, Javier; Perlado Martín, José Manuel; Le Garrec, Bruno
    During the operation of the HiPER first engineering facility, up to 1.2 × 105 MJ/yr of fusion neutrons yields are foreseen. This irradiation level could be distributed in 100 MJ detonations, accounting up to 100 detonations in a single burst, with 10 Hz repetition rate. A burst would take place every month. The dose rates are computed and different concrete shields are evaluated within the target bay. During the operation of the facility the entrance is forbidden inside the bioshield. Between bursts, manual maintenance might be performed inside the bioshield but outside the final optics assembly (FOA) shield. Inside the...

Dentro de los ITS, un campo muy relevante lo constituyen los sistemas de control de la velocidad que suelen considerar, en general, únicamente los límites legales. Los sistemas más sofisticados, incluyen límites adicionales por condicionamientos de seguridad en puntos singulares como curvas, cruces, incorporaciones, etc. Un paso...

  17. The Role of the Spatial and Temporal Radiation Deposition in Inertial Fusion Chambers: The case of HiPER

    Alvarez Ruiz, Jesus; Garoz Gómez, David; Gonzalez Arrabal, Raquel; Rivera de Mena, Antonio; Perlado Martín, José Manuel
    The first wall armour for the reactor chamber of HiPER will have to face short energy pulses of 5 to 20 MJ mostly in the form of x-rays and charged particles at a repetition rate of 5–10 Hz. Armour material and chamber dimensions have to be chosen to avoid/minimize damage to the chamber, ensuring the proper functioning of the facility during its planned lifetime. The maximum energy fluence that the armour can withstand without risk of failure, is determined by temporal and spatial deposition of the radiation energy inside the material. In this paper, simulations on the thermal effect of...

  18. Industrial Applications of Laser Neutron Source

    Nakai, S.; Mima, Kunioki; Kato, Y.; Tanaka, K.; Ikeda, Y.; Azechi, H.; Miyanaga, K.; Nakai, M.; Perlado Martín, José Manuel; Gonzalez Arrabal, Raquel
    The industrial applications of the intense neutron source have been widely explored because of the unique features of the neutron-matter interaction. Usually, intense neutron sources are assembled with fission reactors or high energy ion accelerators. The big size and high cost of these systems are the bottle neck to promote the industrial applications of intense neutrons. In this paper, we propose the compact laser driven neutron source for the industrial application. As the first step of our project for the versatile applications of laser driven neutron source, Li-neutron and/or Li-proton interactions have been investigated for the application to the development...
