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.

autonomous driving
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.

Tytuł:: Risks and consequences of weather hazards on railway infrastructure
Autorzy:: Berg, H. P.
Powiązania:: https://bibliotekanauki.pl/articles/2068913.pdf
Data publikacji:: 2017
Wydawca:: Uniwersytet Morski w Gdyni. Polskie Towarzystwo Bezpieczeństwa i Niezawodności
Tematy:: weather hazards
risk assessment
hazard management
climate change
railway systems
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.

Tytuł:: Risk and safety management : procedures, methods, experiences
Autorzy:: Berg, H. P.
Powiązania:: https://bibliotekanauki.pl/articles/2069571.pdf
Data publikacji:: 2008
Wydawca:: Uniwersytet Morski w Gdyni. Polskie Towarzystwo Bezpieczeństwa i Niezawodności
Tematy:: risk management
safety management
risk management process
risk management tools
Opis:: Risk management is an activity which integrates recognition of risk, risk assessment, developing strategies to manage it, and mitigation of risk using managerial resources. Some traditional risk managements are focused on risks stemming from physical or legal causes (e.g. natural disasters or fires, accidents, death). Financial risk management, on the other hand, focuses on risks that can be managed using traded financial instruments. Objective of risk management is to reduce different risks related to a pre-selected domain to an acceptable. It may refer to numerous types of threats caused by environment, technology, humans, organizations and politics. The paper describes the different steps in the risk management process which methods are used in the different steps, and provides some examples for risk and safety management.

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.

decision making
Opis:: Internationally, probabilistic safety analyses represent the state of the art in the licensing process for new industrial facilities, but increasingly also for evaluating the safety level of older industrial plants, e. g. as part of periodic safety reviews of nuclear power plants. Quantitative safety goals have not yet reached the same level of acceptance. However, this depends on the type of industry. Most of the countries consider those criteria as safety targets rather than as sharply defined boundary values. The Netherlands and the United Kingdom are exceptions, they require demonstration of compliance with legally binding safety goals in the licensing procedure.

Opis:: The estimation of leak and break frequencies in piping systems is part of the probabilistic safety assessment of technical plants. In this paper, the statistical method based on the evaluation of the German operational experience for piping systems with different diameters is described because an earlier estimation has been updated and extended introducing new methodical aspects and data. Major point is the inclusion of structure reliability models based on fracture mechanics calculation procedures. As an example of application the statistical estimation method for leak and break frequencies of piping systems with a nominal diameter of 50 mm (the volume control system of a German pressurized water reactor) was updated. Moreover, the evaluation of the operational experience was extended to 341 years with respect to cracks, leaks and breaks in the volume control system of German pressurized water reactors (PWR). Using the actual data base, new calculations of leak and break frequencies have been performed and the results have been compared with the previous values.

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:: The transformer is the key equipment for electric power transmission. It has been found that main transformer failures require an in-depth assessment because of the high failure frequency and the resultant reliability and safety implications. Transformers are considered as a critical equipment because of the large quantity of oil in contact with high voltage elements. In particular, experience has shown an increasing number of transformer explosions and fires in all types of power plants worldwide. Therefore, these phenomena have been investigated and are discussed in more detail in this paper with regard to causes for these events, potential influence of the age of the transformers and possible diagnostic measure in order to avoid such events. For that purpose different types of databases have been evaluated.

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:: It is state-of-the-art that a Level 1 PSA also includes a fire PSA for all plant operational states. In performing Fire PSA not only the malfunction of the components has to be assessed but also all supply systems and cables have to be traced for a given component. In the past it was assumed in the case of a fire in a compartment that all components and cables in that compartment are not functional anymore. However, this is in many cases a too conservative approach and could lead to overestimated fire induced core damage frequencies. Therefore, a method is necessary to assess in a more realistic manner the effects of cables failures caused by fire. Such a procedure requires a sound data base on equipment, list of cables and their properties as well as cable routing. Two methods are described which are currently developed. One of them is a cable failure mode and effect analysis which is easier to apply in practice.

Opis:: Dependent failures are extremely important in reliability analysis and must be given adequate treatment so as to minimize gross underestimation of reliability. German regulatory guidance documents for PSA stipulate that model parameters used for calculating frequencies should be derived from operating experience in a transparent manner. Progress has been made with the process oriented simulation (POS) model for common cause failure (CCF) quantification. A number of applications are presented for which results obtained from established CCF models are available, focusing on cases with high degree of redundancy and small numbers of observed events.

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:: 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.
