The work deals with nuclear facilities integral safety. On the basis of principles of strategic safety management in dynamically variable world it gives historical development of work with risks in engineering disciplines and present model of management and trade-off with risks used in nuclear facilities. It leans on rules of International Atomic Energy Agency and it characterizes present process model of nuclear facility safety management, its processes and programme for nuclear facility safety upgrading in a context of integral safety directed to existence, security and development of humans.

The article discusses the status of crisis management in a comprehensive management system organizational unit (territory, community, company). For crisis management summarizes the objectives, principles, tasks of research, the specifics of the decision, specific tools, specialty of crisis planning, preparedness principles to solve critical situations and system of response management to critical situations. Based on research that shows the contents of operational crisis plan of the selected municipality with extended competences, which provides qualified response and protection of the population, and is object of engineers lecture at technical universities.

Seismic safety of nuclear facilities has been under account since beginning the 70s of last century. The seismic protection is realised in practice by special seismic safety management and by seismic safety engineering. Their real forms are codified in national building laws and in developed countries with medium and high seismicity. The ground of seismic safety of nuclear facilities in the determination of seismic hazard of site in which the nuclear facility is located, distinguishing and getting control over unacceptable risks that are connected with vulnerabilities of site, buildings, technologies and technical equipment. The present paper deals with the seismic hazard, seismic risk and seismic safety.

Security situation in the EU, world and in each territory continuously changes with time, and therefore, it is necessary to form new safety culture taking into account actual knowledge and experiences with interdependences among the public assets leading to extreme social crises. The present findings show that for good security situation in the Europe the strategic, systemic and proactive approach is necessary to use. The paper summarizes the FOCUS project outputs derived by the Czech Technical University in Prague. It gives deficits in disasters? management and shows the procedures for overcoming them.

The safe community is now at time of globalisation very dependent on a safety level of critical infrastructure ensuring the territory by basic services necessary for humans' live as there are energy, water, food, information etc. Series of events from recent years connected with critical infrastructure showed its high importance. The critical infrastructures represent multistage mutually overlapping systems, i.e. big complex systems, the type of which is a systems system. The paper presents the model for critical infrastructure safety management based on this reality and it shows the way how simply to determine the criticality of individual infrastructures and the whole critical infrastructure.

Modern human being depends on the good work of life-giving infrastructures and supply chains. To ensure the safety of such critical infrastructures and the supply chains it is necessary to determine, introduce and keep appropriate level of protection and countermeasures against real risks. Based on the concept of safe community there are followed couplings created in the human system by live-giving infrastructures and supply chains. The assessment of harms caused by their failures and level of management of these failures reveals open problems in followed domains and these were used for formulation of requirements for future research.
