  • 2013:07 Corrosion of copper in distilled water without molecular oxygen and the detection of produced hydrogen

    In this report, results are presented for copper which has been exposed to pure anoxic water in the temperature interval of 21 °C to 55 °C up to a total of 19 000 hours. Characterisations of copper surfaces after exposure have been performed ex-situ, meaning after termination of the experiment and exposing the specimen to normal atmospheric environment. Ideally characterisation of surfaces...

  • 2019:02 Research within technical safeguard at Chalmers University of Technology during 2016-2017

    Summary The Division of Subatomic and Plasma Physics in Chalmers, formerly the Division of Nuclear Engineering, has performed research in nuclear safeguards and non-proliferation since 2004, with support from SSM and its predecessor, SKI. Due to various organizational and personnel changes in Chalmers, this research was pursued with limited resources and personnel during 2016-06-30 –...

  • 2019:03 Evaluation of the hydrodynamic model in PARET/ANL

    Background The fuel rod analysis program SCANAIR has been developed by IRSN (Institut de Radioprotection et de Sûreté Nucléaire) for analysis of reactivity initiated accidents (RIA) in light water reactors. The Swedish Radiation Safety Authority (SSM) has access to SCANAIR in exchange for annual contributions for its further development. This ensures a possibility for SSM to do...

  • 2019:13 Organisatoriska risker avseende strålsäkerhet i ekonomiskt pressade lägen

    SSM perspektiv Bakgrund Kärnkraftsbranschen befinner sig i en ekonomiskt pressad situation. Höjda säkerhetskrav, åldrade anläggningar som kräver mer underhåll och låga elpriser leder till att resursanvändningen måste maximeras. Stora projekt pågår hos tillståndshavarna i syfte att effektivisera organisationerna. Nedskärningar...

  • 2019:23 Participation in the European Committee for Standardization's workshop regarding civil structures

    SSM perspective Background During the period 2014-2018, a CEN1 workshop (Phase 2 Prospective Group 3 civil works) have been carried out. The aim of the workshop is to provide a base founded on the French standard in order to be able to establish a possible future European standard for the design of civil structures at nuclear power plants. The workshop has identied which additional...

  • 2019:20 Assessment of structures subject to concrete pathologies (ASCET), phase 3

    SSM perspective Background ASCET is an international research project initiated by WGIAGE1 OECD2 / NEA3. WGIAGE Concrete subgroup is a working group within the OECD / NEA whose task is to address issues concerning the maintenance of the integrity of concrete structures, proposals for general principles to optimally handle the challenges of integrity, especially with regard to ageing of...

  • 2009:30 A Review of Evidence for Corrosion of Copper by water

    The planned spent nuclear fuel repository in Sweden relies on a copper cast iron canister as the primary engineered barrier. The corrosion behaviour of copper in the expected environment needs to be thoroughly understood as a basis for the post-closure safety analysis. It has been shown that corrosion may indeed be the primary canister degradation process during the utilised assessment period...

  • 2008:48E Review Statement and Evaluation of the Swedish Nuclear Fuel and Waste Management Co´s (SKB) RD&D Programme 2007

    The review of the RD&D Programmes (Research, Development, Demonstration) prepared by the Swedish Nuclear Fuel and Waste Management Co (SKB) is a recurrent task that the Swedish Nuclear Power Inspectorate (SKI) must carry out as a regulatory authority with the support of reviewing bodies of which the most important is the Swedish Radiation Protection Authority (SSI). The review statement for...

  • 2009:22 Alternative modelling of brittle structures in a sub-area of the SKB candidate area at Forsmark, eastern Sweden

    A reasonable understanding of the character of the bedrock hosting a deep geological repository, i.e. the natural barrier, is an important component in the safety assessment of the deep geological repository for spent nuclear fuel. The structures in the rock, together with the regional stress field, affect the mechanical stability of the bedrock and the ground water transport within the...
