• 2018:25 UO2 fuel oxidation and fission gas release

  Background The Swedish Radiation Safety Authority (SSM) follows the research on fuel performance closely. One aspect that has been the main question of several research projects is the fragmentation of fuel pellets during abnormal heat up. In this project the oxidation of UO2 is scrutinized and its effect on pellet fragmentation, fission gas release and damage of fuel rods has been...

• 2018:24 Structural equation modelling for analysis of human and organizational factors in nuclear power plant control rooms

  SSM perspective Background During the supervisory work of the Swedish Radiation Safety Authority (SSM), a need was identified to develop the methods used when evaluating control room work in the central control rooms of nuclear power plants. Benchmarking is commonly used today, with reference values from earlier Integrated System Validation (ISV), when ISV is available. Often, ISV performs...

• 2018:23 Evaluation of the Impact of the Model Additional Protocol on Non-Nuclear-Weapon States with Comprehensive Safeguards Agreements

  Background The Swedish Radiation Safety Authority (SSM) called for research proposals related to Non-Proliferation. This call resulted in SSM accepting a proposal from the Vienna Center for Disarmament and Non-Proliferation (VCDNP) to evaluate the impact of the implementation of Additional Protocols (AP). The Additional Protocol, which was approved by the International Atomic Energy Agency's...

• 2018:21 Research on Resaturation of Bentonite Buffer

  Background Resaturation processes in the bentonite buffer in a KBS-3 type repository for spent nuclear fuel are complicated and are often illustrated, analysed and modelled multi-disciplinarily as coupled thermal (T), hydrological (H) and mechanical (M) processes with multi-phase flow, elastoplastic evolution in a swelling porous medium. Previous THM-modelling showed that the re-saturation...

• 2018:17 Assessment of structures subject to concrete pathologies (ASCET), phase 2

  Background ASCET is an international research project initiated by WGIAGE1 OECD2 / NEA3. WGIAGE4 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 aging of concrete structures.

• 2018:13 Prestudy - Detectors for variance measurements

  Background The understanding of radiation quality requires knowledge about the energy deposition pattern of ionizing radiation on which models for cellular and sub-cellular damage can be built. Experimental data is fundamental in this context for quality assurance and bench-marking of models and simulations. Direct measurements are also of practical importance for radiation quality...

• 2018:09 Recent Research on EMF and Health Risk, Twelfth report from SSM's Scientific Council on Electromagnetic Fields, 2017

  Background The Swedish Radiation Safety Authority's (SSM) Scientific Council on Electromagnetic Fields monitors current research on potential health risks with a correlation to exposure to electromagnetic fields, and provides the Authority with advice on assessing possible health risks. The Council gives guidance when the Authority must give an opinion on policy matters when scientific testing...
