Revising the Emergency Management Requirements for new generation reactors

The paper presents the application of a new risk-informed methodology for the identification of the Emergency Management Requirements (EMR) to a Generation II, Large size Reactor and a Generation III+ Small Modular Reactor. The results obtained in this test case demonstrate that the actual EMR is conservative, as expected, for the GenII reactor, while the new methodology could be applied for the definition of EMRs for the new generation Nuclear Power Plants, with a possible reduction of the emergency area without loss of safety level. By adopting both probabilistic and deterministic approaches, the study addresses possible accidents and corresponding release scenarios for the two types of reactor, calculates the areas where the accidents have an impact on the population and defines the new EMR considering the health effects on the population.

Emergency management in the highways of the future. A performance-based multilayered ITS architecture design proposal

Emergency management is one of the key aspects within the day-to-day operation procedures in a highway. Efficiency in the overall response in case of an incident is paramount in reducing the consequences of any incident. However, the approach of highway operators to the issue of incident management is still usually far from a systematic, standardized way. This paper attempts to address the issue and provide several hints on why this happens, and a proposal on how the situation could be overcome. An introduction to a performance based approach to a general system specification will be described, and then applied to a particular road emergency management task. A real testbed has been implemented to show the validity of the proposed approach. Ad-hoc sensors (one camera and one laser scanner) were efficiently deployed to acquire data, and advanced fusion techniques applied at the processing stage to reach the specific user requirements in terms of functionality, flexibility and accuracy.

An approach to stakeholders involvement in the preparedness for nuclear and radiological emergency response & recovery in Spain

The elaboration of a generic decision-making strategy to address the evolution of an emergency situation, from the stages of response to recovery, and including a planning stage, can facilitate timely, effective and consistent decision making by the response organisations at every level within the emergency management structure and between countries, helping to ensure optimal protection of health, environment, and society. The degree of involvement of stakeholders in this process is a key strategic element for strengthening the local preparedness and response and can help a successful countermeasures strategy. A significant progress was made with the multi-national European project EURANOS (2004-2009) which brought together best practice, knowledge and technology to enhance the preparedness for Europe's response to any radiation emergency and long term contamination. The subsequent establishment of a European Technology Platform and the recent launch of the research project NERIS-TP ("Towards a self sustaining European Technology Platform (NERIS-TP) on Preparedness for Nuclear and Radiological Emergency Response and Recovery") are aimed to continue with the remaining tasks for gaining appropriate levels of emergency preparedness at local level in most European countries. One of the objectives of the NERIS-TP project is: Strengthen the preparedness at the local/national level by setting up dedicated fora and developing new tools or adapting the tools developed within the EURANOS projects (such as the governance framework for preparedness, the handbooks on countermeasures, the RODOS system, and the MOIRA DSS for long term contamination in catchments) to meet the needs of local communities. CIEMAT and UPM in close interaction with the Nuclear Safety Council will explore, within this project, the use and application in Spain of such technical tools, including other national tools and information and communication strategies to foster cooperation between local, national and international stakeholders. The aim is identify and involve relevant stakeholders in emergency preparedness to improve the development and implementation of appropriate protection strategies as part of the consequence management and the transition to recovery. In this paper, an overview of the "state of the art" on this area in Spain and the methodology and work Plan proposed by the Spanish group within the project NERIS to grow the stakeholder involvement in the preparedness to emergency response and recovery is presented.

MOIRA-PLUS use in decision making on the long-term management of contaminated freshwater bodies and catchments

In the mid-long-term after a nuclear accident, the contamination of drinking water sources, fish and other aquatic foodstuffs, irrigation supplies and people?s exposure during recreational activities may create considerable public concern, even though dose assessment may in certain situations indicate lesser importance than for other sources, as clearly experienced in the aftermath of past accidents. In such circumstances there are a number of available countermeasure options, ranging from specific chemical treatment of lakes to bans on fish ingestion or on the use of water for crop irrigation. The potential actions can be broadly grouped into four main categories, chemical, biological, physical and social. In some cases a combination of actions may be the optimal strategy and a decision support system (DSS) like MOIRA-PLUS can be of great help to optimise a decision. A further option is of course not to take any remedial actions, although this may also have significant socio-economic repercussions which should be adequately evaluated. MOIRA-PLUS is designed to allow for a reliable assessment of the long-term evolution of the radiological situation and of feasible alternative rehabilitation strategies, including an objective evaluation of their social, economic and ecological impacts in a rational and comprehensive manner. MOIRA-PLUS also features a decision analysis methodology, making use of multi-attribute analysis, which can take into account the preferences and needs of different types of stakeholders. The main functions and elements of the system are described summarily. Also the conclusions from end-user?s experiences with the system are discussed, including exercises involving the organizations responsible for emergency management and the affected services, as well as different local and regional stakeholders. MOIRAPLUS has proven to be a mature system, user friendly and relatively easy to set up. It can help to better decisionmaking by enabling a realistic evaluation of the complete impacts of possible recovery strategies. Also, the interaction with stakeholders has allowed identifying improvements of the system that have been recently implemented.

KATS: A Knowledge Acquisition Tool Based on Electronic Document Processing

This paper describes a particular knowledge acquisition tool for the construction and maintenance of the knowledge model of an intelligent system for emergency management in the field of hydrology. This tool has been developed following an innovative approach directed to end-users non familiarized in computer oriented terminology. According to this approach, the tool is conceived as a document processor specialized in a particular domain (hydrology) in such a way that the whole knowledge model is viewed by the user as an electronic document. The paper first describes the characteristics of the knowledge model of the intelligent system and summarizes the problems that we found during the development and maintenance of such type of model. Then, the paper describes the KATS tool, a software application that we have designed to help in this task to be used by users who are not experts in computer programming. Finally, the paper shows a comparison between KATS and other approaches for knowledge acquisition.

Estudio del módulo icrp del sistema jrodos de ayuda a la toma de decisiones en emergencias nucleares y radiológicas

Este proyecto se basa en el sistema JRodos de ayuda a la toma de decisiones en tiempo real en caso de emergencias nucleares y radiológicas. Tras una breve descripción del mismo, se presentan los modelos de cálculo que utiliza el sistema y la organización modular en la que se estructura el programa. Concretamente este documento se centra en un módulo desarrollado recientemente denominado ICRP y caracterizado por tener en cuenta todas las vías de exposición a la contaminación radiológica, incluida la vía de la ingestión que no se había tenido en cuenta en los módulos previos. Este modelo nuevo utiliza resultados obtenidos a partir de la cadena de escala local LSMC como datos de entrada, por lo que se lleva a cabo una descripción detalla del funcionamiento y de la ejecución tanto del módulo ICRP como de la cadena previa LSMC. Finalmente, se ejecuta un ejercicio ICRP usando los datos meteorológicos y de término fuentes reales que se utilizaron en el simulacro CURIEX 2013 realizado en el mes de noviembre de 2013 en la Central Nuclear de Almaraz. Se presenta paso a paso la ejecución de este ejercicio y posteriormente se analizan y explican los resultados obtenidos acompañados de elementos visuales proporcionados por el programa. This project is based on the real time online decision support system for nuclear emergency management called JRodos. After a brief description of it, the calculation models used by the system and its modular organization are presented. In particular, this paper focuses on a newly developed module named ICRP. This module is characterized by the consideration of the fact that all terrestrial exposure pathways, including ingestion, which has not been considered in previous modules. This new model uses the results obtained in a previous local scale model chain called LSMC as input. In this document a detailed description of the operation and implementation of both the ICRP module and its previous LSMC chain is presented. To conclude, an ICRP exercise is performed with real meteorological and source term data used in the simulation exercise CURIEX 2013 carried out in the Almaraz Nuclear Power Plant in November 2013. A stepwise realization of this exercise is presented and subsequently the results are deeply explained and analyzed supplemented with illustrations provided by the program.

Flooding through the lens of mobile phone activity

Natural disasters affect hundreds of millions of people worldwide every year. Emergency response efforts depend upon the availability of timely information, such as information concerning the movements of affected populations. The analysis of aggregated and anonymized Call Detail Records (CDR) captured from the mobile phone infrastructure provides new possibilities to characterize human behavior during critical events. In this work, we investigate the viability of using CDR data combined with other sources of information to characterize the floods that occurred in Tabasco, Mexico in 2009. An impact map has been reconstructed using Landsat-7 images to identify the floods. Within this frame, the underlying communication activity signals in the CDR data have been analyzed and compared against rainfall levels extracted from data of the NASA-TRMM project. The variations in the number of active phones connected to each cell tower reveal abnormal activity patterns in the most affected locations during and after the floods that could be used as signatures of the floods - both in terms of infrastructure impact assessment and population information awareness. The epresentativeness of the analysis has been assessed using census data and civil protection records. While a more extensive validation is required, these early results suggest high potential in using cell tower activity information to improve early warning and emergency management mechanisms.

Desarrollo de soluciones a la gestión de las emergencias como Sistema Complejo: aplicación a la Comunidad de Madrid

En la presente tesis se desarrolla una metodología y una herramienta informática que permite abordar de forma eficaz y eficiente problemas de gestión de los recursos intervinientes en emergencias. Se posibilita, a través de indicadores innovadores como el Índice de Respuesta Operativa (I.RO.), una evaluación correcta del riesgo real en función de los medios disponibles y de su probabilidad de colapso, permitiendo desarrollar una optimización de la utilización estos medios tanto en el presente como en escenarios futuros. Para su realización se describen inicialmente los principales actores que intervienen en las emergencias evaluándolos y mostrando las sinergias existentes. Se define y analiza, a través de sistemas complejos socialmente inteligentes (SCSI) el “ciclo de global de las emergencias”: planificación, prevención, detección, intervención, rehabilitación y el tratamiento informativo de la crisis. Del mismo modo se definen los distintos escenarios donde se interviene y cómo se puede prever su evolución. Para ello se establecen unas tipologías de siniestros y se identifican las similitudes o diferencias entre ellos. También se describe y modela el problema de la toma de decisiones a nivel de planificación operativa, desde la localización de instalaciones, tipologías de parques de bomberos, etc. Para demostrar la viabilidad de la metodología desarrollada se realiza su aplicación al territorio de la Comunidad Autónoma de Madrid obteniendo resultados satisfactorios a partir de los datos existentes. Es un estudio totalmente innovador y de amplia repercusión no solo en la gestión de las emergencias sino también en otros campos tales como el de estrategia militar, comercial, de gestión de organizaciones, etc. ABSTRACT This Phd Thesis presents a method and software tool that allows facing, in an efficient and effective manner, the resources involved in emergencies. It enables a correct assessment of the real risk as a function of the available resources and its collapse likelihood. This is achieved by mean of some novel indexes such as the Operative Response Index. Therefore, it allows a current and future optimization of the use of available resources. First, it describes the main factors affecting emergencies, assessing them and showing existing synergies. Then, it defines and analyse through complex systems socially intelligent (CSSI) the overall emergency cycle: planning, prevention, detection, intervention, rehabilitation and informative crisis coverage. Similarly, it defines the scenarios of intervention and how to forecast their progress. To this end, some typologies of disasters are defined, identifying commonalities. Moreover, it also describes and model decision-making issues at operationalplanning level, such as the location of facilities, typologies of fire stations, etc. In order to prove the feasibility of the developed methodology, it is applied to the Comunidad Autónoma de Madrid, getting successful results from the existing data. This Phd Thesis is an innovative study with far reaching impact, not only in emergency management but also in other fields such as the military, business strategy, organizational management, etc.

La protección civil municipal: análisis de los distintos tipos de gestión y propuesta metodológica de planificación

Mediante la elaboración de esta tesis doctoral se pretende diseñar un sistema para la realización del plan de autoprotección en industrias con riesgo de incendio dentro de un polígono industrial. Para desarrollar esta línea de investigación se realizará una investigación cartográfica así como un reconocimiento visual de las distintas empresas industriales, de actividades heterogéneas, seleccionadas por su emplazamiento y condiciones. Este tipo de industria es esencial en el sistema económico nacional, ya que dota de recursos y servicios al tejido social, además de tener una relación directa con la generación de riqueza y por tanto incide de forma positiva en el empleo de cualquier región. Estas razones y otras son determinantes para fomentar el progreso, si bien nunca a expensas de la seguridad de los empleados que hacen posible la línea de producción así como de los posibles viandantes que transcurran por la zona de impacto en caso de incidentes como por ejemplo un incendio que afecte a cualquiera de los locales y/o empresas que se emplazen en los denominados polígonos industriales. La tesis incluye trabajos experimentales de los que se extraen recomendaciones y conclusiones encaminadas a la optimización de la instrumentalización utilizada, las técnicas de observación, diseño y cálculo necesarias que determinarán el acercamiento al método propuesto para nuestra valoración del riesgo por incendio. Las posibles emergencias que pueden darse a nivel de industrias localizadas en polígonos industriales son diversas y numerosas. De todas ellas se elige abordar el caso de “incendio” por su casuística más numerosa. No obstante, la planificación orientada desde el prisma de la investigación de esta tesis puede estenderse a cualquier otro riesgo, lo que se aportará como líneas futuras de investigación. Las aproximaciones y etapas de los trabajos que forman parte de esta investigación se han integrado en cada capítulo y son las siguientes: En primer lugar un capítulo de Introducción, en el que se realiza una reflexión justificada de la elección del tema tratado, se formula la hipótesis de partida y se enumeran los distintos objetivos que se pretenden alcanzar. En el segundo capítulo, titulado Aspectos de la Protección Civil en la Constitución Española de 1978, se ha realizado un estudio exhaustivo de la Constitución en todo lo relacionado con el ámbito de la protección, haciendo especial énfasis en las distintas competencias según el tipo de administración que corresponda en cada caso, así como las obligaciones y deberes que corresponden a los ciudadanos en caso de catástrofe. Así mismo se analizan especialmente los casos de Guerra y el estado de Alarma. En el tercer capítulo, titulado Repuesta de las administraciones públicas ante emergencias colectivas, se trata de formular el adecuado sistema de repuesta que sería preciso para tratar de mitigar desastres y catástrofes. Se analizan los distintos sistemas de gestión de emergencias constatando en cada caso los pros y los contras de cada uno. Se pretende con ello servir de ayuda en la toma de decisiones de manera coherente y racional. El capítulo cuarto, denominado Planes Locales de emergencia. Estudio en las distintas administraciones, se ha pormenorizado en la presentación así como puesta en funcionamiento de los planes, comparando los datos obtenidos entre ellos para concluir en un punto informativo que nos lleva a la realidad de la planificación. Para la realización y desarrollo de los capítulos 5 y 6, llamados Análisis de la Norma Básica de Autoprotección y Métodos de evaluación del riesgo de Incendio, se estudia la normativa actual en autoprotección prestando atención a los antecedentes históricos así como a todas las figuras que intervienen en la misma. Se analizan los distintos métodos actuales para la valoración del riesgo por incendio en industrias. Este aspecto es de carácter imprescindible en la protección civil de los ciudadanos pero también es de especial importancia en las compañías aseguradoras. En el capítulo 7, Propuesta metodológica, se propone y justifica la necesidad de establecer una metodología de estudio para estos casos de riesgo por incendio en industrias para así, acortar el tiempo de respuesta de los servicios de emergencia hasta la zona, así como dotar de información imprescindible sobre el riesgo a trabajadores y transeúntes. El último capítulo se refiere a las Conclusiones, donde se establecen y enuncian una serie de conclusiones y resultados como consecuencia de la investigación desarrollada, para finalizar esta tesis doctoral enunciando posibles desarrollos y líneas de investigación futuros. ABSTRACT The development of this thesis is to design a system for the implementation of the plan of self-protection in industries with risk of fire in an industrial park. To develop this line of research will be done cartographic research as well as visual recognition of the distinct and heterogeneous industrial companies selected by its location and conditions. This type of industry is an essential part in the economic national system providing economic resources to society as well as with a direct relationship in unemployment. For this reason it is crucial to promote their progress, but never at the expense of the security of the employees that make the line of production as well as possible walkers that pass by the area of impact in the event of a fire affecting the company. The thesis includes experimental works which are extracted recommendations and conclusions aimed at optimization of used exploit, techniques of observation, design and calculation needed to determine the approach to the method proposed for our assessment of the risk from fire. The approaches and stages of works that are part of this research have been integrated into each chapter and are as follows: In the first chapter, holder introduction, perform a supporting reflection of the choice of the subject matter, is formulated the hypothesis of departure and listed the different objectives that are intended to achieve. In the second chapter, holder aspects of Civil Protection in the Spanish Constitution of 1978, examines an exhaustive study of the Constitution in everything related to the scope of protection. With an emphasis on individual skills according to the type of management with corresponding in each case, as well as the obligations and duties which correspond to citizens in the event of a catastrophe. Also analyzes the particular cases of war and the State of alarm. In the third chapter, holder public administrations collective emergency response, discussed trafficking in defining the proper system response that would be precise to address disasters and catastrophes. We discusses the different systems of emergency management in each case, we pretend the pros and cons of each. We tried that this serve as decision-making aid coherent and rational way. The fourth chapter is holder Local Emergency Plans (LEP). Study on the different administrations, has detailed in the presentation as well as operation of the LEP, comparing the data between them to conclude in an information point that leads us to the reality of planning. For the realization and development of chapters 5 and 6, holder Analysis of the basic rule of self-protection and fire risk assessment methods, paying attention to the historical background as well as all the figures involved in the same studies with the current rules of self-protection. The current methods for the estimation of the risk are analyzed by fire in industries. This aspect is essential in the civil protection of the citizens, but it is also of special importance for insurance companies. The seventh chapter, holder Methodological proposal, we propose and justifies the need to establish a methodology for these cases of risk by fire in industries. That shorts the response time of emergency services to the area, and provides essential information about the risk to workers and walkers. The last chapter refers to the Conclusions, laying down a series of results as a consequence of the previous chapters to complete billing possible developments and research future.

Accident Management Actions In An Upper-Head Small-Break Loss-Of-Coolant Accident With High-Pressure Safety Injection Failed

Since the Three Mile Island accident, an important focus of pressurized water reactor (PWR) transient analyses has been a small-break loss-of-coolant accident (SBLOCA). In 2002, the discovery of thinning of the vessel head wall at the Davis Besse nuclear power plant reactor indicated the possibility of an SBLOCA in the upper head of the reactor vessel as a result of circumferential cracking of a control rod drive mechanism penetration nozzle - which has cast even greater importance on the study of SBLOCAs. Several experimental tests have been performed at the Large Scale Test Facility to simulate the behavior of a PWR during an upper-head SBLOCA. The last of these tests, Organisation for Economic Co-operation and Development Nuclear Energy Agency Rig of Safety Assessment (OECD/NEA ROSA) Test 6.1, was performed in 2005. This test was simulated with the TRACE 5.0 code, and good agreement with the experimental results was obtained. Additionally, a broad analysis of an upper-head SBLOCA with high-pressure safety injection failed in a Westinghouse PWR was performed taking into account different accident management actions and conditions in order to check their suitability. This issue has been analyzed also in the framework of the OECD/NEA ROSA project and the Code Applications and Maintenance Program (CAMP). The main conclusion is that the current emergency operating procedures for Westinghouse reactor design are adequate for these kinds of sequences, and they do not need to be modified.

Application of the agency theory for the analysis of performance-based mechanisms in road management

El WCTR es un congreso de reconocido prestigio internacional en el ámbito de la investigación del transporte, y aunque las actas publicadas están en formato digital y sin ISSN ni ISBN, lo consideramos lo suficientemente importante como para que se considere en los indicadores. This paper develops a model based on agency theory to analyze road management systems (under the different contract forms available today) that employ a mechanism of performance indicators to establish the payment of the agent. The base assumption is that of asymmetric information between the principal (Public Authorities) and the agent (contractor) and the risk aversion of this latter. It is assumed that the principal may only measure the agent?s performance indirectly and by means of certain performance indicators that may be verified by the authorities. In this model there is presumed to be a relation between the efforts made by the agent and the performance level measured by the corresponding indicators, though it is also considered that there may be dispersion between both variables that gives rise to a certain degree of randomness in the contract. An analysis of the optimal contract has been made on the basis of this model and in accordance with a series of parameters that characterize the economic environment and the particular conditions of road infrastructure. As a result of the analysis made, it is considered that an optimal contract should generally combine a fixed component and a payment in accordance with the performance level obtained. The higher the risk aversion of the agent and the greater the marginal cost of public funds, the lower the impact of this performance-based payment. By way of conclusion, the system of performance indicators should be as broad as possible but should not overweight those indicators that encompass greater randomness in their results.
