Opis:: Natural hazards are frequently causing disturbances for different types of infrastructures, in particular for transport systems. Flooding and storm are considered as major threats to these systems. Based on examples of natural hazards’ impact on roads, possible approaches of vulnerability assessment are described. In order to reduce the threats resulting from natural hazards on road transport, appropriate technical countermeasures to increase resilience and robustness for continuous road safety and mobility are necessary. Moreover, the behaviour of the driver is also an important factor to avoid accidents in case of specific weather conditions. Autonomous driving may support a reduction of accidents in the future and, in particular, necessary evacuation processes in cases of wildfires or hurricanes.

Opis:: Weather-related hazards are already among the factors most frequently causing disturbances for railways. Flooding and storm are considered major threats to the system. Climate change might in the long run produce new kinds of hazards and threats to the railway system, but the climate change will principally involve a strengthening of the already known threats, in terms of increased frequency as well as increased intensity. Based on examples of natural hazards’ impact on railways, possible approaches of vulnerability assessment are described which could also address potential consequences of climate change. In order to reduce the effects of weather hazards technical countermeasures are necessary, but also an appropriate risk management as, e.g., required for flooding in the European Union.

Opis:: Weather-related hazards are among the most frequent causes for disturbances of critical infrastructures. Flooding, tsunamis and sea level rise are examples of major threats to all types of nuclear facilities located at the seaside or at rivers. We report about exemplary investigations concerning weather-related hazards for the North Sea and the Baltic Sea. Climate change is expected to increase the already known threats but, in the long term, may also lead to new kinds of hazards. A possible future climate evolution, e.g. from warm (interglacial) to cold (glacial) periods, is not only a topic for seaside industrial facilities but also of concern in the long term safety assessment of deep geological nuclear waste repositories, in particular for high level waste, on the Baltic sea.

Opis:: Risks relating to external hazards, either natural or man-made, have to be taken into consideration in the design of nuclear and other industrial facilities. These risks have to be studied to guarantee the availability and efficiency of safety functions which, e.g. in the case of power reactors, enable a safe shutdown, maintain the reactor in a safe shutdown state, ensure the residual heat removal and the containment of radioactive products. With a view to design protection against risks related to external hazards, these hazards have to be assessed in an appropriate manner. The methods used can be either deterministic or probabilistic. In both cases, the method strongly relies on observations (e.g. flood records) that are processed to define a maximum event for the respective facility design. Moreover, the validity of these records over a certain time frame like 100 years has to be checked. Coping with external hazards such as flooding in the future requires an in-depth assessment taking into account new data, further developed methodologies and criteria. Some of these ideas, developments and applications are provided.

assessment
Opis:: Operating experience from different types of industrial installations has shown that combinations of different types of different hazards occur during the entire lifetime of the installations. Typically site specific occurring hazards cause or induce other hazards to occur. In particular, natural hazards rarely happen alone. Thus, it is very important to note that almost any event combination of hazards is possible and that it is necessary to identify these interactions and find ways to mitigate the effects of hazard combinations. Therefore, it is a basic task to investigate and assess the relevant combination of hazards not only for a single installation but for the respective site/industrial park. In that context domino effects and cascade effects pose particular challenges for risk management to prevent industrial accidents.

Opis:: The International Atomic Energy Agency has started a few years ago a project to enhance the existing framework for safety goals for nuclear installations and currently is finalizing a publication aimed to provide guidance for a more holistic approach to establishing and utilizing safety goals for nuclear installations. The intention was to develop a more consistent and holistic framework for safety goals that would be composed of a hierarchical structure of qualitative concepts (e.g. defense in depth, various safety requirements) and quantitative risk metrics. The safety goals should be technology neutral at the higher level and should cover both normal operation and accident conditions as well as the risk to workers, public, and the environment. In the paper the development of a hierarchical framework for safety goals is described including a methodology to derive lower-(more technical) safety goals from the higher goals. Moreover a process for assessing the degree of compliance with the safety goals and their consistent use is provided. As an example the developed framework is applied to the German regulatory framework for nuclear installations but focused on nuclear power plants.

Opis:: The implementation of the CSM regulation by the European Commission in 2009 which harmonizes the risk assessment process and introduces a rather new concept of judging changes within the European railway industry. This circumstance has risen the question how other technology sectors handle the aspect of modifications and alterations. The paper discusses the approaches for judging the significance of modifications within the three transport sectors of European railways, aviation and maritime transportation and the procedure which is used in the area of nuclear safety. We will outline the similarities and differences between these four methods and discuss the underlying reasons. Finally, we will take into account the role of the European legislator and the fundamental idea of a harmonization of the different approaches.

Opis:: Internal and external hazards analysis methods have been used recently to evaluate operating nuclear power plants (NPP) and to identify the resilience of NPP in case of hazards and potential needs for modification of plant systems and procedures as well as to support design of new plants The external hazards risk contribution has been modeled in many NPP PSA (at least for some external hazards) over the last decade, including events occurring during shutdown and low power operations. Recently, a revision of the German nuclear safety regulations has been successfully completed and these regulations entitled “Safety Requirements for Nuclear Power Plants”, also requiring a detailed investigation of internal and external hazards and combinations of different hazards applying deterministic and probabilistic safety assessment methods.

Opis:: Because of the growing operational age of nuclear power plants, the ageing management of structures, systems and components used in these plants is gaining an important role. Technical systems are subject to timedependent and operationally caused ageing phenomena with modifications of originally given characteristics and, thus, of relevance in terms of safety. Especially physical ageing is of importance. Therefore, a comprehensive ageing management is required. In the context of an integrated safety management it has to be shown how to integrate the safety related issues of ageing into probabilistic safety assessment (PSA). In particular the question is to be answered whether the effort for the execution of an ageing PSA is justified, in particular if the safety significant effects of ageing can be identified and quantitatively estimated. Method for prioritization of the components in the nuclear power plant considering implication of their ageing on safety of the nuclear power plant is presented. On the basis of an actual report on ageing management in German nuclear power plants and a literature survey, this paper tries to estimate the necessity and value for the introduction of an ageing PSA in Germany.

Opis:: Nuclear power plants benefit from a sophisticated and comprehensive safety regime that has been established over the years. However, the security regime for nuclear power plants is far less developed than the safety regime. Although adopting (and adapting) certain elements of the nuclear safety regime could significantly strengthen the nuclear security regime, at least four challenges are likely to surface: national sovereignty, information transparency, lack of policy consensus, and challenges of regime harmonization. Seek an optimal balance between mandatory international standards and voluntary actions and endorse consideration of additional binding and non-binding international safety and security requirements.

Opis:: Critical infrastructure risks pose a special problem for all countries. The companies that own these infrastructures operate in competitive and regulated environments. However, it is neither practical nor possible to protect critical infrastructures from all hazards. For the government, the continuity of these infrastructures is critical to many of its fundamental missions: economic stability and growth, national security, public safety, and quality of life. In that context resilience has become an important factor to fulfil the task of the critical infrastructure protection. Thus, the development of a framework to establish resilience goals could be helpful.

Opis:: As in every industry at risk, the human and organizational factors constitute the main stakes for maritime safety. Furthermore, several events at sea have been used to develop appropriate risk models. The investigation on maritime accidents is, nowadays, a very important tool to identify the problems related to human factor and can support accident prevention and the improvement of maritime safety. Part of this investigation should in future also be near misses. Operation of ships is full of regulations, instructions and guidelines also addressing human factors and safety culture to enhance safety. However, even though the roots of a safety culture have been established, there are still serious barriers to the breakthrough of the safety management. One of the most common deficiencies in the case of maritime transport is the respective monitoring and documentation usually lacking of adequacy and excellence. Nonetheless, the maritime area can be exemplified from other industries where activities are ongoing to foster and enhance safety culture.

Opis:: To meet the increased demands of new exhaust and CO₂ limits a research project of Volkswagen R&D, the Technical University of Poznan and the Ostfalia University of Applied Sciences has been initiated; its main target was the development and adaptation ICOS (Internal Combustion Optical Sensor) – an infrared sensor of LaVision for on-line measurements of EGR-rate in cylinder of an engine under operation. The objective of the project was to determine by different optical signals the CO₂ concentration, the EGR rate and residual gas which are cycle-resolved in the cylinder. In this paper the principle of measurement of optical indication has been described. The infrared sensor was validated by a one-cylinder diesel engine and compared to a synchronously running fast gas sampling system (CSV). Finally the practical application of various parameter variations is illustrated in the determination of the EGR and residual gas rate. Thus a new measurement technique for the development of future generations of engines introduced.
Aby umożliwić spełnienie wymagań nowych norm emisji spalin oraz spełnić limity emisji CO₂ podjęto projekt badawczy z udziałem: Volkswagen R&D, Politechniki Poznańskiej i Ostfalia University of Applied Sciences; jego głównym celem był rozwój i adaptacja ICOS (Internal Combustion Optical Sensor) – czujnika podczerwieni firmy LaVision dla bieżących pomiarów stopnia recyrkulacji spalin w cylindrze pracującego silnika. Celem projektu było określenie na podstawie różnych sygnałów optycznych wartość stężenia CO₂, stopnia recyrkulacji spalin (EGR – rate) oraz ilości spalin, które znajdują się w cylindrze przed rozpoczęciem procesu spalania. W artykule przedstawiono zasadę pomiaru zawartości spalin z wykorzystaniem czujnika optycznego. Możliwość zastosowania czujnika podczerwieni została potwierdzona przez badania na jednocylindrowym silniku wysokoprężnym, a otrzymane wyniki porównano z systemem do szybkiego pobierania próbek gazu (CSV). Przedstawiono również wyniki pozwalające na określenie recyrkulacji spalin oraz reszty spalin przy różnych parametrach pracy silnika. Nowa technika pomiarowa pozwala na dostosowanie nowoczesnych silników spalinowych do przyszłych norm ochrony środowiska i tworzy podstawę dla rozwoju przyszłych generacji silników spalinowych.

Opis:: We consider semi-Markov reliability models of multi-component systems with a discrete state space, general enough to include systems with maintenance or repair. We assume that for all system states the functioning or failure of each component is specified. In this setup we propose a component importance measure which is close in spirit to the classical steady state Barlow–Proschan importance measure for repairable binary coherent systems. We discuss our importance measure to some extent, highlighting the relation to the classical Barlow–Proschan measure, and present formulas expressing it in terms of quantities easily obtained from the building blocks of the semi-Markov process. Finally an example of a two-component cold standby system with maintenance and repair is presented which illustrates how our importance measure can be used in practical applications.
