• 2012:23e Integrated assessment of radiation safety in health and medical services

  The county councils do not meet the Swedish Radiation Safety Authority’s requirements in terms of radiation safety. This implies that their health and medical services have deficiencies in this area that could lead to serious consequences for patients and staff, a conclusion based on the Swedish Radiation Safety Authority’s compilation of information from the nine county councils that...

• 2013:20 Terrestrial Biosphere Modelling of C-14 Research

  The need to address radiological impacts from 14C released to the biosphere has been recognized for some time. However, because of its role in biological processes and its ecological cycling, the standard methods employed to model long-term radionuclide transport and accumulation in the biosphere cannot be used satisfactorily for 14C. In 2011, the Swedish Radiation Safety Authority (SSM)...

• 2013:19 Eighth report from SSM:s Scientific Council on Electromagnetic Fields

  The Swedish Radiation Safety Authority`s (SSM) scientific council monitors the current research situation and gives the authority advice on the assessment of risks, authorization and optimization within the area. The council gives guidance when the authority shall give an opinion on policy matters when scientific testing is necessary. The council shall submit a written report on the current...

• 2013:16 Technical Note, Assessment of PWR fuel depletion and of neutron multiplication factors for intact PWR fuel copper canisters – main review phase

  SKB (Svensk Kärnbränslehantering AB) in 2011 applied to the Swedish government for approval of a proposed solution for disposal of used fuel from Swedish nuclear power reactors and some relatively minor quantities of other fissile material. This Technical Note contains results of a recent review of the SKB methods used to determine the influence of reactor depletion on keff of intact...

• 2013:14 Approaches used for Clearance of Lands from Nuclear Facilities among Several Countries – Evaluation for Regulatory Input

  SSM has recently established new regulations for clearance of materials, rooms, buildings and land (SSMFS 2011:2). The regulations specify that license holders for practices involving ionising radiation shall take measures after the cessation of the practice to achieve clearance of rooms, buildings and land. The regulations state nuclide specific clearance levels in becquerel per m2 for rooms...

• 2013:13 Review of Dismantling Costs - Nuclear Installations

  In this study three reviews of cost assessments for some smaller nuclear installations are presented for which nuclear waste liabilities shall be accrued according to the Financing Act (Lag (2006:647) om finasiella åtgärder för hanteringen av restprodukter från kärnteknisk verksamhet). It is expected that these reviews will contribute to develop premium quality assessments...

• 2013:10 Qualification of Electrical Equipment in Nuclear Power Plants - Management of ageing

  The purpose of this report is to describe programs and tools for assessment of accomplished and documented qualification with respect to ageing of electrical equipment and for development of complimentary ageing management programs. In addition to description of complete programs for management of ageing, tools for validation of the status with regard to ageing of installed (“old”) equipment...

• 2013:09 An Application of the Functional Resonance Analysis Method (FRAM) to Risk Assessment of Organisational Change

  The objective of this study was to demonstrate an alternative approach to risk assessment of organisational changes, based on the principles of resilience engineering. The approach in question was the Functional Resonance Analysis Method (FRAM). Whereas established approaches focus on risks coming from failure or malfunctioning of components, alone or in combination, resilience engineering...

• 2013:08 Licensing of safety critical software for nuclear reactors

  It is widely accepted that the assessment of software cannot be limited to verification and testing of the end product, i.e. the computer code. Other factors such as the quality of the processes and methods for specifying, designing and coding have an important impact on the implementation. Existing standards provide limited guidance on the regulatory and safety assessment of these factors.

• 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...
