• 2008:30 A model for fission gas release from mixed oxide nuclear fuel

  Nuclear fuel containing mixed oxide (MOX) pellets have been used since the 1960's. MOX fuel pellets are made from a mixture of uranium and plutonium oxide. MOX allows the large quantities of fissile isotopes produced and remaining in spent nuclear fuel from light water reactors to be recycled. Producing MOX fuel can be seen as a method to more efficiently use the natural uranium since...

• 2007:18 Marvikenreaktorn - ett industripolitiskt utvecklingsprojekt i otakt med tiden

  Den statliga Atomenergiutredningen tillsattes 1955 och publicerade sin rapport i början av 1956. Med utgångspunkt från diskussionerna inom utredningen offentliggjorde Vattenfall samtidigt planer på två reaktorprojekt Adam och Eva. Det statligt finansierade forsknings- och utvecklingsföretaget AB Atomenergi (föregångare till nuvarande Studsvik AB) presenterade...

• 2007:10 DECOVALEX-THMC - Task D

  The DECOVALEX project is an international cooperative project initiated by SKI, the Swedish Nuclear Power Inspectorate, with participation of about 10 international organizations. The name DECOVALEX stands for DEvelopment of COupled models and their VALidation against Experiments. The general goal of this project is to encourage multidisciplinary interactive and cooperative research on...

• 2007:23 On Safety Management, A Frame of Reference for Studies of Safety Management with Examples From Non-Nuclear Contexts of Relevance for Nuclear Safety

  The authors present the theoretical framework. There they also discuss the pros of using the system perspective to build a useful frame of reference of safety management using non- nuclear organizations; this as a way to create models useful for the nuclear power industry but based on general understanding of the concept of safety management. The chosen organizations are used extensively to...

• 2007:22 Safety Management An Introduction to a Frame of Reference Exemplified with Case Studies from Non-Nuclear Contexts

  A systems perspective has been applied on safety management that will be the foundation for the frame of reference the authors intend to build during the three-year long project. The case studies are presented and form illustrations of both high quality safety management and weaknesses of the safety management and take a look at information feedback about the risks of the systems. An...

• 2007:05 Development of an Input Model to MELCOR 1.8.5 for Oskarshamn 3 BWR

  An input model has been prepared for the Oskarshamn 3 rector. Demonstrations calculations, at current nominal operating conditions in Oskarshamn 3 for 3300 MW thermal power, were performed for three cases: (1) initial, steady-state conditions, (2) total loss of AC power and (3) large steam line LOCA. The results are presented in the report. 200 Lars Nilsson SKI English An input model has been...

• 2007:10 Radiological consequences of radionuclide releases to sewage systems from hospitals in Sweden

  The report addresses radioactive discharges to sewers originating from hospitals, mainly in the form of the excretion of patients treated with radioisotopes for diagnostic or therapeutic purposes. Assessments of doses to the public, including sewage workers, arising from such discharges are performed. Doses are compared against the exemption level of 10 μSv/a and the dose constraint of 100...

• 2007:06 Personalstråldoser inom vård, forskning och icke kärnteknisk industri i Sverige under 1999-2005

  Denna rapport presenterar en sammanställning av stråldoser till personal inom icke kärntekniska områden i Sverige åren 1999 - 2005. Kollektivdosen har under den här tidsperioden varierat mellan 1,2 och 1,6 manSv. Störst bidrag till kollektivdosen ger arbetstagare som arbetar med joniserande strålning inom sjukvården. De högsta medeldoserna erhålls...

• 2007:04 Recent Research on EMF and Health Risks. Fourth annual report from SSI’s Independent Expert Group on Electromagnetic Fields, 2006

  This year’s report includes a preamble in which the work process of the group is described. In particular the methods for evaluation of the results of studies as well as for synthesizing the scientific evidence within a research area are described. A recent childhood leukaemia study from Japan is in line with previous epidemiologic findings. The effects of RF fields on many different...

• 2007:02 Strålmiljön i Sverige

  Rapporten beskriver, och redovisar resultat från, den strålmiljöövervakning som bedrivits i Sverige sedan 1950-talet. Genomsnittliga doser till befolkningen och till speciella befolkningsgrupper redovisas också. En stor del av övervakningen har rört nedfallet och spridningen i ekosystemen av radioaktiva ämnen från de atmosfäriska kärnvapenproven...
