In order to maintain a high safety level at a nuclear power plant it is important not only to measure the reliability of the components and systems of the plant, but also to investigate how the plant responds to human actions. One of the most hazardous situations in managing a power plant is fire occurring in critical areas. This study concerns the prospect of the local fire brigade to suppress a fire that has started in one of the most critical rooms for maintaining high reactor safety. The model created gives an indication on the possibilities of succeeding in suppressing a fire. In order to get a more reliable fire fighting the following advice are given:- Let the fire brigade go rounds in the plant together with the personnel, during which recommended fire suppressing methods are determined to avoid long preparation time in an actual situation.- Prepare rooms with two subsystems to make them partly with no voltage.- Give the fire brigade better feedback from actual events on nuclear power plants.- Education and training in suppressing fires in electrical equipment.The probabilistic safety assessment strives to be as realistic as possible.

The safety and safety work on OKG, Oskarshamns Kraftgrupp, is supervised by SKI, Swedish nuclear power inspectorate. The task of SKI is to inspect that the nuclear power plants of Sweden runs in a safe way. The proprietor of the permit who runs nuclear power plants has the responsibility to maintain the required safety to run a plant. SKI publishes a number of statue books that OKG has to meet to be able to run the plants. SKI recommends in SKIFS 2 004:1, that OKG work with the safety requirements of IAEA.

This thesis is written on behalf of Skanska, Väg- och Anläggning Stockholm Mälardalen, vid Nya Karolinska Sjukhuset i Solna, NKS. The report has resulted in recommendations for the method of soil stabilizations of soil nailing, excavation of slope and fiber reinforced shotcrete, which is the most suitable method from a safety and a cost point at the NKS.The aim of this thesis was to investigate whether fiber reinforced shotcrete increases slope stability, with the focus being on the total stability. The main goal was to investigate which method of soil stabilization is the most suitable for the slopes that are analyzed in this report. Through studying literature, the authors have gained an understanding about the theoretical background for the given problem. Through calculations and analyses of the slopes, safety factors have been acquired.

Studien genomfördes hösten 2013 på ett logistikföretag i Sverige, med syfte att studera sä-kerhetsklimatets potentiella påverkan på medarbetarnas förhållningssätt till incidentrapporte-ring. Utifrån teorier om säkerhetsklimat skapades en enkät, innehållande ett urval frågor från samtliga av de sju säkerhetsklimatsdimensioner, som det nordiska frågeformuläret NO-SACQ-50 (Kines et al., 2011) innehåller. Dessa kompletterades med frågor som fokuserade på uppfattningen av incidentrapportering. Resultaten visar att säkerhetsklimatet påverkar uppfattningen av incidentrapportering, som chefer och medarbetare delar. Ju bättre klimatet är desto större blir benägenheten att ha en positiv uppfattning av incidentrapporteringen, även när man tar personlighetsdraget CFC (Consideration of Future Consequences) i beak-tande.

At Forsmark nuclear power plant the rather old-fashioned software COPTA is used in containment safety analysis. There exists a desire within the organisation to introduce a more modern software with ability to more detailed modeling and increased usability.The goal of this thesis was to evaluate the software APROS in containment safety analysis. APROS models describing one of the containments at Forsmark NPP have been developed. Two simulations of typical containment incidents, one of them a large pipe break, have been made where containment safety parameters such as pressure and temperature are studied. Results are analyzed and verified against results from corresponding COPTA models.

Researchers, planners, and government agencies agree that road safety for children must be a priority and in particular that children should have a safe and secure way to travel to and from school regardless of age or the distance travelled. In Sweden, child traffic safety is a key part of the country?s Nollvision, a long-term traffic policy goal of ?no deaths or serious injuries?. Unfortunately, many countries have recorded increases in child traffic accidents as the percentage of parents who drive their children to school and thus congestion around schools has increased. Common strategies include traffic safety education for children, the redesign and improvement of traffic infrastructure, bicycle training, and carpooling.This thesis assesses the traffic problem around Ludvigsberg School in the district Valbo in Gävle, Sweden.

There are certain organizations that manage to handle risk in such a successful way that they almost stay error-free, in spite of the fact that they daily face the risks of accidents. These organizations are usually given the name High Reliability Organizations (HRO). While the most common example is that of a nuclear plant the variety of what organizations can fit into the category is extensive.The purpose of this study is to describe safety culture and theories about HRO and how these can be found in practise within an organization.This qualitative research uses influences of ethnography in its method. The ethnographical approach was picked due to the field of the study and the cultural context in which it is set.The results of the study identify a number of elements sorted into four themes. These themes are deemed compatible or non-compatible with relevant existing theories.

The purpose of this paper has been to explore how Internet is perceived, with reference to youth, risk and responsibility, by a section of the population in North-West Skåne in Sweden. The questions central to our area of interest were:- Where does the responsibility for a safe Internet environment lie?- What measures are believed to be able to make Internet safer?- Are the opinions about safety on the Internet affected by an individual'sknowledge and experience of the Internet?- Is there an awareness of which institutions are involved in Internet safety?We compared the results of our survey with earlier surveys done by SAFT and Eurobarometern. Additionally we compared various categories such as gender and age to discover any patterns within the groups.There is a clear conflict in the answers given by the group we studied, between the desire to have access to all the information and experiences Internet has to offer and the desire to protect youth from inappropriate content and/or influences from unknown sources. While we did find concern regarding issues of safety we did not find any indication of "moral panic"..

This Projects goal was to develop a manual, which was to be used as help for a fishing company in the making of an SMS (Safety Management System). The manual was going to follow the guidelines presented by the IMO (International Maritime Organisation) and the Swedish Transport Agency. The projects client was a smaller fishing company that was about to build a fishing vessel.The work has been carried out as a project, it was finished within the schedule and the client was most satisfied with the result. The client has used the manual in the making of the Safety Booklet (SMS) and they are now certified according to the rules of the Swedish Transport Agency..

In Trollhättan municipality approximately 700 school bus stops are in service. To ensure high quality of the performance of school bus operations, with focus on traffic safety, it was decided to conduct a survey of bus stops including assessments of risks.This master thesis aims to identify the factors affecting road safety at bus stops and pedestrian connections, and to conduct an inventory and analysis of selected sites in Trollhättan municipality. The work also aims to show examples of how risk assessment should be performed in future studies. A risk analysis model provided by the Swedish Transport Administration is supplemented and used in a field study. The risk assessment is based on, inter alia, traffic flow, visibility distance, lighting, speed of traffic and the presence of bus shelter.

The aim for the project was to develop a risk analyse tool for measuring the fire safety level in Cultural Heritage buildings of Visby, Gotland. In 1995 Visby were taken into the Unesco:s World Heritage List with the explanation ?Visby is an outstanding example of a Northern European walled Hanseatic town which has in a unique way preserved its townscape and its extremely valuable buildings? One of the demands for the tool was that it should be easy to use and result into a ranking level in examined buildings. The user of the tool is recommended to be personnel in the fire department. To develop the tool a Multi Attribute Decision Making (MADM) method was used.

Background: It is required that health care professionals continuously work with patient safety and quality improvements, and the skills of registered nurses are significant in this work. However, quality improvement also requires commitment and knowledge about how to improve health care and ensure patient safety. There is a lack of studies that highlights the importance of supportive functions for this work. Nurses in clinical settings can be utilized as facilitators that make things easier for other health care professionals who are engaged in quality improvement and patient safety. In order to gain understanding about the significance and needs of nurses with a role of facilitator, it is urgent to learn from their experiences of facilitating quality improvement in health care.Aim: The aim was to study nurses? experiences of facilitating quality improvement of nursing care, patient safety and multi-professional collaboration in health care.Method: Semi-structured qualitative interviews were performed with ten registered nurses who had experience of being in the role of facilitators.

I have always lived around mines and around people work­ing with mines. They are a natural part of my life and, inev­itably, a great interest of mine. When time came to make a decision for a degree project, focusing on the mine context felt as natural as breathing.In LKABs underground mines, safety in fire accidents is a great priority. Of outmost importance for the escape is to have a personal gas filter for filtration of smoke and/or gas. My design project resulted in a concept which is aimed at shortening the user journey from the start of the accident until the user has applied the Personal safety solution and is ready to escape.Throughout the project I?ve been working with a context which is heavily regulated, and all problems are serious, important ones.
