• 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...

• 2007:44 An Introduction to Nuclear Non-Proliferation and Safeguards

  The compendium at hand will be used both within an outside Sweden as course material. It is partly a result from the work done by TKM (Training and knowledge management), which is a working group within Esarda (European Safeguards Research and Development Association) that on a yearly basis educates students from all over Europe. The intention is that the material shall be used in conjunction...

• 2007:43 ProLBB - A Probabilistic Approach to LeakBefore Break Demonstration

  The SKI regulation SKIFS 2004:2 allows for the use of Leak Before Break (LBB) as one way to provide assurance that adequate protection exists against the local dynamic consequences of a pipe break. The way to demonstrate that LBB prevails relies on a deterministic procedure for which a leakage crack is postulated in certain sections of the pipe based on the leak detection capability of the...

• 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...

• 2005:18 Kartläggning av kvalitetssäkringsrutiner för DAP-mätare i svensk sjukvård

  SSI har undersökt hur DAP-mätare kvalitetssäkras på svenska sjukhus. DAP-mätare används vid mätningar av patienstråldoser vid röntgenundersökningar och det är viktigt att mätresultaten är tillförlitliga och att mätresultat från olika sjukhus kan jämföras. En förutsättning för detta är...

• 2007:14 Utvärdering av miljökvalitetsmålet Säker strålmiljö

  Utvärderingen av Säker strålmiljö är ett bidrag till Miljömålsrådets samlade bedömning av det nationella miljömålsarbetet. Rapporten beskriver och bedömer strålmiljön i Sverige, införda styrmedel, genomförda åtgärder och uppföljningsarbetet. Vidare bedöms möjligheten att nå Säker...

• 2007:30 Modelling the Interaction of Low pH Cements and Bentonite

  Concrete and cement are used in constructions as well as in conditioning of waste inrepositories for radioactive waste. It is well known that in the hyperalkaline conditions (pH > 12) of standard cement pore fluids, there is potential for deleterious effects upon the host rock and other EBS materials, notably bentonite, in geological repositories. Low pH cements are beginning to be considered...

• 2007:08 DECOVALEX-THMC - Task B

  This report summarizes the work contributed to Phase 2 of Task B of the international DECOVALEX-THMC project, which took place during the period of March 2004 to May 2006. The Phase 2 work incorporated the use of a wide range of numerical models to simulate the failure of a number of intact rock core samples, from the APSE tunnel at Äspö HRL, as tested in uniaxial compression and other...

• 2007:11 Review of Quality Assurance in SKBs Repository Research Experiments

  SKB is preparing a license application for the construction of a final repository for spent nuclear fuel in Sweden. This application will be supported by the safety assessment SR-Site for the post-closure phase. As a preparation for SR-Site SKB has recently produced the SRCan safety assessment, which is currently in review. The assessment of long-term safety is based on a broad range of...
