MCNP-modell för beräkning av neutrondos och DPA på reaktortanken vid Ringhals 2

In this report an MCNP (Monte Carlo N-Particle) model is described for the reactor Vessel at Ringhals 2. The model is validated against the specific activity in neutron dosimeters, extracted in 1977, 1984 and 1994. The validation showed that the calculations of the model are within the requirements of a maximum of 20 percent uncertainty for every neutron dosimeter except one, extracted after the first cycle. The uncertainty of this cycle was mostly due to the operation data rather than to the MCNP model.The model has been used to investigate various questions concerning radiation damage. The reliability of the traditional measure of radiation damage, fast neutron flux (En > 1MeV) has been evaluated.  This has been done by taking the ratio for this and another measure of radiation damage, DPA (Displacement Per Atom), for various positions and layers.

Icke-linjära modelleringsteknikerav förspänd betongkonstruktion : Reaktorinneslutningen på Forsmark 3

A new material model, for the FE-program ADINA, has been verified against twoexperiments. One unreinforced concrete beam and one reinforced concrete beam.The model, DF-concrete, has the possibility to estimate true concrete. However theresults indicate that in order to be sure that the estimations are true, there ought tobe data from the true concrete to verify against.Two FE-models have simulated the behavior of a ring-shaped part of the nuclearcontainment Vessel. The results from the first, frictionless, model agree with similarsimulations and hand calculations for high pressures in the containment Vessel. Thesimulations of the nuclear containment Vessel show cracking in the concrete after10-11 bars of over pressurization.

Skådespelarens hemligheter : Om Zeamis estetik och värdet av det som inte framträder

This work examines how the aesthetics of Japanese actor and playwright Zeami Motokiyo (1346-1443) offers insight into the value of the unseen elements in art, specifically in the art of acting. What acting makes appear is likened to a Vessel, which creates an empty space of what doesn?t appear. This non-appearing element is at the same time what gives the Vessel its function. N? theater is described as an art of suggesting, giving a background to Zeami?s theories.

Sensorfusion för undervattensrobot i kärnteknisk miljö med Kalman filtrering

WesDyne TRC AB is a fully owned subsidiary of the global WestinghouseElectric Corporation. WesDyne is a world leader in non-invasive methods for theinspection of nuclear power plants. One of the inspection platforms used to scanfor defects in and around the welds in the reactor Vessel is called the T-crawler.The T-crawler operates under water in a radioactive environment by stepping onthe Vessel (reactor tank) inner wall using suction cups. The environment is harshand many traditional positioning sensors are not suitable for implementation. Thisthesis investigates the possibility to use a gyroscope and a pressure sensor tocreate an alternative and independent positioning system.

RMA - framtidens lösning eller en lösning för framtiden? : RMA - en ny syn på utnyttjandet av militära medel som kräver anpassningsåtgärder på dagens moderna förbandstyper?

The last two decades have changed the society from the Industrial Age to the Information Age. The technological development, especially in IT, has caused a ?Revolution in Military Affairs?. However; how big are the changes RMA will give, or will it even change the foundation of the Art of War and if so, in what way?RMA has three cornerstones DBA, DS and PE all closely integrated in an NCW-concept.

Vidareutveckling och utvärdering av operatörsplatser på svenska stridsfartyg

The ability to handle potentially dangerous and hostile situations on a military Vesselrequires that the equipment works effectively with the personnel that use it. It is importantthat this equipment can be used by different people. An operator on a military Vesselshall be able to handle information about hostile threats, navigation and the steering ofunmanned vehicles. A operator console should therefore be constructed in such a waythat the operator can handle a large flow of information. And the information given bythe technical system should be displayed correctly to facilitate the operators ability tohandle and interpret the information correctly, in order for the operator to make thecorrect decision at any given moment.

Parallel Registration of Ships

In present there is no Swedish legislation regulating bareboat registration of Swedish ships. Despite this absence however shipowners with Vessels already registered in the Swedish Vessel Register do not hesitate to take advantage of the positive aspects of bareboat registration and thereby allowing the registration of their ships in another State as well. The fact that there is a lack of legislation in this area has left a legal loophole resulting in Swedish ships being registered in a second State without any regulation providing options or protection for the different parties involved. With this as a background, the main objective of this thesis is to analyze parallel registration of ships, its consequences and the future of dual registration in Sweden. To fulfil this objective another aim is to impart a collected legal and economical presentation of the problems that may occur when a bareboat chartered Vessel is registered in two different States simultaneously.

Järnhandel och eliter i Arboga, år 1769-1775.

In this essay, Neolithic potsherds from Alby, Öland has been examined. The purpose was to investigate the connection between the lipid residues and the Vessel shapes and ornament. To solve the attempt lipid and morphological analyses were executed. The lipid analysis revealed traces of different food residues and the morphological method showed various shapes and decors. The result indicates that the Alby ceramics has been used for cooking/storage of different fish and meat dishes, as well as vegetables and that the vegetables doesn?t derive of cereals..

Utredning om en ökad biologisk behandling av matavfall i Halmstads kommun

Environment and sustainable development are very current topics in today's society, bothnational and international. The government's bill 2004/05:150 ?Swedish environment objectives - a common commission? contains several environmental quality objectives, that in turn is divided up in smaller secondary objectives. One of the secondary objectives says: ?Latest year 2010 shall at least 35% of the food waste from households, restaurants, largescale kitchens and shops be recycled through biological treatment.

Guide till upprättande av säkerhetshandbok

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..

Utredning av alternativa distributionssystem för Holmen Paper

Holmen Paper is one of Sweden?s leading manufacturer of paper, with two Swedish production facilities located in Norrköping and Hallstavik. The European continent constitutes the company?s largest customer base which makes the company?s distribution system an integral part of the business. Historically, much of the produced paper has been transported by Vessels, as Vessels allow large volumes of goods and deliveries to markets which are difficult to reach with other modes of transportation.

Design och utvärdering av power system stabilizer isynkrongenerator

The purpose of this report was to investigate what characterizes a good psychosocialwork environment, and whether it may have impact on a Vessel's safe voyage. Thisreport is proposed to increase the understanding of what creates a good psychosocialwork environment and its potential effect on safety at sea. In order to find out thesuccess factors for a good work environment group interviews were conducted in socalledunstructured focus groups. During these conversations, the participants discussedfreely by the question "what is a good psychosocial work environment for you?? Thesuccess factors were thereafter applied on selected accident reports, to investigate theextent to which they were represented and taken into account.The results of the study show three categories of factors: colleagues, communicationand competence, where colleagues are the main contribution to a good psychosocialwork environment.
