• 2007:42 Regleringen av matarvattenflödet i en PWR - Med exempel från Ringhals 3

  Rapporten ger en redovisning av kända och potentiella problem med matarvatten- regleringen i tryckvattenreaktorer, problem som i vissa fall förekommit tidigare internationellt. Vidare ges en detaljerad beskrivning av matarvattenregleringen vid Ringhals 3, som kan sägas vara representativ även för övriga svenska tryckvatten- reaktorer. Analysresultaten visar att R3:s...

• 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...

• 2007:12 Development of a constitutive model for the plastic deformation and creep of copper and its use in the estimate of the creep life of the copper canister

  The copper-iron canister for disposal of nuclear waste in the Swedish Programme has a design life exceeding 100,000 years. Whilst the operating temperature and operating stress are modest, the very long design life does require that the likely creep performance of the canister should be investigated. Many studies have been carried out by SKB but these have all involved very short duration...

• 2007:17 Spent Fuel Dissolution and Source Term Modelling in Safety Assessment

  SKI is preparing to review the license applications being developed by the Swedish Nuclear Fuel and Waste Management Company (SKB) for a final repository for the geological disposal of spent nuclear fuel (SFL-2) in the year 2009. As part of its preparation, SKI is conducting a series of technical workshops on key aspects of the Engineered Barrier System (EBS) and spent fuel. This workshop...

• 2007:19 An Applied Study of Implementation of the Advanced Decommissioning Costing Methodology for Intermediate Storage Facility for Spent Fuel in Studsvik, Sweden with special emphasis to the application of the Omega code

  The aim of this applied study has been to describe in a systematic way an appropriate methodological sequence for cost estimation of crucial parameters in decontamination and decommission processes. The work has been limited to older nuclear installations and facilities. Furthermore, it may be envisaged that the process of estimating the parameters of decommissioning is one of the main issues...

• 2007:02e Radiation Environment in Sweden, summary

  The radiation environment to which the population of Sweden is exposed is dominated by medical investigations and background radiation from the ground and building materials in our houses. That is the conclusion of the first general Swedish summary of environmental monitoring data and dose calculations within the field of radiation. The report shows that people’s behaviour in the form of...

• 2006:06 Kontrollrumsfilosofi: Principer för kontrollrumsutformning och kontrollrumsarbete

  Sedan flera år är begreppet kontrollrumsfilosofi etablerat inom svensk kärnkraftindustri. Syftet med en kontrollrumsfilosofi är att beskriva principerna för och de förutsättningar som personalen behöver för att kunna arbeta på ett säkert sätt. Kontrollrumsfilosofin ska ange interna krav och riktlinjer för utformning och ändringar...

• 2006:36 Mechanical Integrity of Canisters Using a Fracture Mechanics Approach

  This report presents the methods and results of a research project for Swedish Nuclear Power Inspectorate (SKI) about numerical modeling of mechanical integrity of cast-iron canisters for the final disposal of spent nuclear fuel in Sweden, using combined boundary element (BEM) and finite element (FEM) methods The objectives of the project are: 1) to investigate the possibility of initiation...

• 2005:44 Urananrikning med gascentrifugering

  Den nu resulterande rapporten berör kortfattat teorin och några generella principer för gascentrifugering, vilken utrustning som kan komma ifråga, indikatorer på anrikning med gascentrifugering, mm. Vi har valt att låta rapporten vara översiktlig utan att gå in på detaljer. Detta för att inte sprida information som kan vara känslig ur kommersiell...
