• 2013:29 Regulatory Approaches in Nuclear Power Supervision

  The objective of this follow-up study was to support SSM in further understanding regulatory approaches and how they can be combined as part of effective strategies. The survey was intended to assist SSM in identifying current standards, experiences, and practices in the regulation of nuclear power plants. The results will also be valuable for the participating authorities as well as other...

• 2013:24 Modelling of nuclear fuel cladding under loss-of-coolant accident conditions

  We present a unified model for calculation of zirconium alloy fuel cladding rupture during a postulated loss-of-coolant accident in light water reactors. The model treats the Zr alloy solid-to-solid phase transformation kinetics, cladding creep deformation, oxidation and rupture as a function of temperature and time in an integrated fashion during the transient. The fuel cladding material...

• 2013:04 Research and Development Program in Reactor Diagnostics and Monitoring with Neutron Noise Methods, Stage 18

  The program executed in Stage 18 consists of the following three parts: Application of CoreSim with a two-dimensional model of vibrating fuel assemblies, for the calculation of ex-core detector noise throughout a fuel cycle; An investigation of the neutron noise, induced by propagating perturbations, in various thermal and fast reactor systems, in two-group theory; A consistent derivation of...

• 2013:35 Technical Note, Rock Mechanics – Confidence of SKB’s models for predicting the occurrence of a damage zone around the excavations – Main Review Phase

  This assignment, performed at Southwest Research Institute, focusses on evaluating SKB’s assessment of potential occurrence of damaged rock zones (also referred to as excavation-damaged zone or EDZ) around underground excavations at the site. This report presents the authors’ evaluation of SKB’s assessment in the specific area based on questions raised by SSM. The evaluation includes...

• Tubbrott i en tryckvattenreaktor

  Svenska tryckvattenreaktorer har tre ånggeneratorer som innehåller tusentals tuber. Tuberna är en säkerhetsbarriär mellan kärnkraftverkets primär- och sekundärkrets.Om en tub går av måste reaktorn stoppas och den skadade ånggeneratorn isoleras. Faktabladet beskriver vad som händer vid ett tubbrott i en tryckvattenreaktor.

• Bränslebyte i kokvattenreaktor

  Faktabladet beskriver hur bränslets byts i en kokvattenreaktor. Cirka en femtedel av bränsleelementen i en reaktor byts årligen. Bytet görs under den årliga revisionen, när reaktorn är avställd.
