• 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...

• 2007:43 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...

• 2007:31 Säkerhets- och strålskyddsläget vid de svenska kärnkraftverken 2006

  Säkerhetsproblemen i el-systemen vid reaktor Forsmark 1 var den dominerande händelsen i de svenska kärntekniska anläggningarna under 2006. Händelsen har fått stor betydelse för synen på tillförlitligheten när det gäller säkerhetssystems funktioner och har väckt stor internationell uppmärksamhet. I samband med SKI:s utredning...

• 2007:26 Safety Culture Enhancement Project Final Report

  At the International Conference on Safety Culture in Nuclear Installations, organized by IAEA in 2002, one concluding remark was that the regulators should encourage a sincere interest in safety culture among licensees. In line with this SKI wanted to explore a proactive path to encourage the licensees in their safety culture work. SKI also had the ambition to gain more information on the MTO...

• 2007:31e Safety and Radiation Protection at Swedish Nuclear Power Plants 2006

  Safety related problems in the electric systems of the Forsmark 1 reactor were the dominant event in Swedish nuclear power plants in 2006. The incident has had a significant impact on our attitude towards the reliability of how safety systems function both in Sweden and abroad. In connection with SKI’s review of the incident it was found that the company’s management system was not...

• 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...

• 2007:20 Internationellt samarbete inom OECD/NEA 2006 avseende nukleär kriticitetssäkerhet

  Deltagande i internationellt samarbete inom OECD/NEA:s Nuclear Science Committee och dess Working Party on Nuclear Criticality Safety har fortsatt under 2006 med stöd av SKI. Inga stora projekt där jag varit mycket aktiv har pågått. Däremot har jag deltagit i arbetet genom granskning av förslag till slutrapporter, vid bedömning av nya projekt samt i fortsatt...

• 2007:39 Influence of Crack Morphology on Leak Before Break Margins

  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...

• 2007:06 Probabilistic Safety Goals - Phase 1 -Status and Experiences in Sweden and Finland

  Based on a series of interviews and on literature reviews as well as on a limited interna- tional over-view, the project has described the history and current status of safety goals in Sweden and Finland. A number of issues were discussed more in detail, including the status of the safety goals in view of the fact that they are often exceeded, strategies for handling violations of safety...

• 2007:14 Review of experimental data for modelling LWR fuel cladding behaviour under loss of coolant accident conditions

  This project has contributed to the research goal of giving a basis for SKIs supervision by means of evaluating experimental data and modelling the nuclear fuel cladding during a design base accident. The project has also contributed to the research goal to develop the competence about licensing of fuel at high burnup, which is an important safety issue. The results are useful as such, but...
