Ett kärnkraftverk producerar inte bara elenergi, det är även beroende av det bl.a för kylning av reaktorn. Därför finns åtskilliga säkerhetssystem för reservkraft och ett av dessa system är dieseldrivna generatorer. På en av reaktorerna i Oskarshamn har man fyra sådana generatorer men de börjar bli gamla och det finns ett behov av att skaffa en ny generator för att kunna frigöra de gamla en i taget och göra en grundlig genomgång på dem. Det här examensarbetet kom till för att undersöka om det är möjligt att få fram en ny generator som går att använda som ersättare medans en gammal plockas ner för total genomgång. Det omfattar även kringutrustningen till generatorerna som är lika viktig för dess funktion.För att få fram vad som krävs har jag behövt sätta mig in i hur systemet är uppbyggt och fungerar.

Sociala medier ?r en del av dagens ton?rskultur, d?r Instagram, Snapchat och TikTok ?r de popul?raste apparna bland barn och unga. Forskning visar att anv?ndandet av filter p? sociala medier genererar m?jligheter att (om)f?rhandla sin identitet samt att anv?ndandet kan leda till att unga utvecklar orealistiska kroppsideal. F?r att f? en ?verblick ?ver f?ltet g?rs en strukturerad forsknings?versikt.

This report contains a study of replacing nuclear power with biofuel. The nuclear plant, OKG north of Oskarshamn in Sweden has been chosen and an extensive literature study about the nuclear plant has been implemented. The main aspect of this report is the availability of biofuels and whether it would be economically sustainable. Sweden?s most common biofuels are examined with regard to scope of use and potential.

Many social services cases have been reviewed in the media during the last years. One of those cases is ?Lasse and Karin?, handled by the Social Services in Oskarshamn in 2002. Lasse and Karin had their son taken into custody by the Social Services and the case was reviewed in national media. Through this case the Social Services received much attention, of which most was negative, and their handling of the case was greatly criticized.

There are many children in Sweden today, approximately between 100 000 and 200 000, who have parents or a parent that abuses alcohol or other drugs. In this research paper we have reviewed some of the literature concerning these children and their situation. The purpose of this research paper was to make an interview study of a group activity for children that have parents or a parent, who abuses alcohol or other drugs.This research paper is based on interviews conducted with two children and four group leaders. We compared the children's opinions about the group activity to the opinion of the group leaders of what the group activity has given the children. We also wanted to compare our interview study with other similar studies that has been made within this subject.

AbstractTrendanalys av rapporterade störningar vid de svenskakärnkraftverkenAnalysis of trends in reported safety-related events atSwedish nuclear power plantsSafdar KargarThis degree project was conducted at the Swedish Radiation Safety Authority (SSM)as part of the bachelors program in Nuclear Engineering at Uppsala University duringthe spring of 2011.The Swedish Radiation Safety Authority (SSM) has developed a Windows baseddatabase called ?ASKEN? during later years. In this database more than 12 000 eventreports are stored sorted in three categories, category 1, 2 and 3. The databasecontains events from the start of Oskarshamn 1 in 1972 till present time.All nuclear power plants in Sweden are obliged to report any deficiency in theirbarriers and/or the defense in depth in obedience to SSMFS 2008:1.When a failure is detected or there is reasonable suspicion of a deficiency, the eventreport should be classified as a deficiency of category -1, 2 or 3 [1].The event reports are logged and archived in the register of SSM. The SSM task forceAnalys av Störningar på elproducerande Kärnkraftverk (the ASK-group), evaluates allincoming event reports and categorizes them according to established criteria.The aim of the project is to study and analyze the event reports in the database andidentity interesting observations and trends which should be investigated morethoroughly by deeper analysis to establish any positive or negative trends of reportedevents. .

I denna uppsats har vi undersökt hur styrdokumenten inom ett medelstort företag i Västsverige påverkar organisationskulturen och samspelet mellan personalen. Vårt syfte har varit att öka förståelsen kring hur eller om dessa dokument kan styra och påverka individerna och kulturen inom en organisation. Vi har utgått ifrån ett institutionellt etnografiskt och etnometodologiskt angreppssätt i vår ansats in i fa?ltet. Vi har genom detta sett till dokumenten som en makronivå, translokal nivå och samspelet som en mikronivå, lokal nivå inom företaget.

This thesis investigates the overall risks of flooding over the Design Basis Flooding Level (DBFL) at the Swedish nuclear power plants (Oskarshamn, Ringhals and Forsmark), using statistical data and methods, but also considers historical events which might affect the overall risk of flooding at the specified sites.Considering the nuclear accident which happened in Fukushima in conjuction with the earthquake and tsunami which struck eastern Japan on 11 March 2011, operators and licensors of nuclear power plants all over the world conducted reviews and investigations on the overall risks posed to the plants from external events. One important such event is extreme water level.One part of the thesis includes an extreme value analysis (using Generalized Extreme Value distribution and Generalized Pareto distribution) of water level data from SMHI (Sweden's Meteorological and Hydrological Institute) measured at stations close to the Swedish nuclear power plants. The results of the statistical studies indicate that considering the return period used in the thesis (100 000 years), the water levels at the Swedish nuclear power plants are not expected to exceed DBFL.The other part of the thesis consists of a historical study of extreme weather-related events. The results of this study indicate that no historical events seem to have occured which would indicate a higher risk of flooding than the one suggested by the statistical study. .

Detta arbete inom prestationsmätning av effektiv logistik är utfört på Scanias produktionsenhet MB i Oskarshamn. Denna produktionsenhet tillverkar hytterna till Scanias lastbilar på europamarknaden, från plåtrulle till färdigmålad hyttkaross. Produktionsenheten MB består av en pressverkstad, en karossverkstad och ett måleri.Uppgiften i detta arbete är att utveckla ett antal mätetal för prestationsmätning av MB:s internlogistik, och utifrån dessa ge förslag på förbättringsmöjligheter i verksamheten.Uppgiften löses genom att använda Bourne och Neelys metoder för utveckling av mätetal, så som en framgångskarta för den kritiska framgångsfaktorn effektiv logistik och utformandet av ett definitionsblad, vilket explicit definierar varje mätetal. Detta tillsammans med Parmenters definitioner angående mätetal och arbetssätt vad det gäller prestationsmätning, avser att spegla moderna tillvägagångssätt för prestationsmätning och för implementering av dessa i ett företag.De mätetal som rekommenderas för implementering i MB:s logistiska verksamhet är trucktimmar per hytt, leveranspålitlighet, lageryta, energianvändning per hytt för transporter och materialhanteringskostnad per hytt. Flera förbättringsförslag rekommenderas också vad det gäller den förbättringspotential som finns vid införandet av en gemensam materialhanteringsfunktion på MB.

Vi j?mf?r konvergensen, effektiviteten och tillf?rlitligheten av 13 l?sare fr?n paketet PETSc, vilka anv?nder olika f?rkonditionerare f?r att l?sa ekvationen.

The thesis was performed at Forsmarks Kraftgrupp AB in the department ofmechanical engineering, FTCM. Forsmark nuclear power plant has had problems with cracks in some of the controlrods which are placed in the reactor at Forsmark 3. To investigate the cause of this,material samples were taken from five of the damaged control rods. This sampling ofthe rods resulted too short rods to be transported in the shipping container to theinterim storage facility for used nuclear fuel in Oskarshamn. Control rods are crucial components in a nuclear reactor, regulating the reactoreffect by blocking or unblocking fuel rods. Control rods which have been in thereactor are always handled under water in order to protect against the radiation theyemit. The task was to design a control rod adapter that extends the control rod sotransport can be performed from Forsmark. The goal of the work was a complete setof blueprints so the control rod adapter can be manufactured and mounted on theshort control rods and then be transported to the interim storage facility. The work began with mapping of how control rods normally being handled from thereactor to the interim storage facility.

Syftet med studien ?r att unders?ka upplevelser hos yrkesverksamma som arbetar med att till?mpa djurunderst?tt arbete med hund inom ?ldreomsorgen och/eller arbetar i en s?dan verksamhet d?r hundinterventioner till?mpas. Studien str?var efter att f? insyn i de yrkesverksammas upplevelser om hundinterventioner inom ?ldreomsorgen, med fokus p? hur dessa insatser kan inverka p? ?ldres sociala delaktighet, psykiska v?lbefinnande och motivation till socialt engagemang. Studien genomf?rdes genom kvalitativa intervjuer med sex personer som arbetade antingen p? ett ?ldreboende d?r djurunderst?tt arbete med hund implementerats, eller som hundf?rare som bes?kte s?dana verksamheter.

In order to facilitate design and maintenance of such a large and complex site as a nuclear power plant, all system functions must be described in a stringent way. In the past, these descriptions consisted of text documents and logical diagrams, but today there are an increasing number of object-oriented programs available on the market which might be used for this purpose. This Master Thesis has made a closer study of one of these programs named Rational Rose. The principal of the program is to facilitate software design and development, not to create models of plants. However, using the program the same way as developing software, specifying actors then gradually extend the model with use cases, use cases diagrams etc, the same methods can be used when modelling plants.

Inom det normativa forskningsf?ltet har en debatt r?rande kompensatorisk r?ttvisa uppst?tt i ljuset av att vissa suver?na territorium riskerar att g? f?rlorade till f?ljd av klimatf?r?ndringarnas effekter. Vilken sorts kompensation en s?dan moraliskt distinkt f?rlust rimligtvis b?r f?ranleda relateras i h?g grad till huruvida k?randeparten i dilemmat uppfattas vara territoriets befolkning som kollektiv grupp (ett s.k. kollektivistiskt f?rh?llningss?tt) eller som enskilda individer (ett s.k.
