• 2014:26 Improved reference and relative dosimetry of small radiation therapy photon beams

  Data tables on detector corrections for beam output measurements are provided for a large number of detectors (small air and liquid ionization chambers, silicon diodes, TLD and alanine) manufactured by major vendors, for 6 MV photons from clinical accelerators and for two Leksell Gamma Knife® models. They have been calculated with the PENELOPE Monte Carlo system at an uncertainty of 0.1%.

• 2014:25 En standardiserad svensk nomenklatur för strålbehandling

  Arbetet med att ta fram en standardiserad svensk nomenklatur för strålbehandling har i huvudsak utförts av en referensgrupp som har varit knuten till forskningsuppdraget. Referensgruppen har bestått av läkare och sjukhusfysiker från landets universitetssjukhus. Den framtagna standarden har harmoniserats med publicerade internationella standarder. I den här rapporten...

• 2014:15 Multivariatanalys av radioaktivitetsdata från utsläpp till luft och vatten från Studsviksanläggningarna och i omgivningen av Studsvik

  Syftet med denna studie var att undersöka korrelationer mellan uppmätt utsläppt radioaktivitet från Studsviksanläggningarna och uppmätta halter radioaktivitet i omgivningen av Co-60, Cs-134, Cs-137, Eu-152, Eu-154 och Mn-54. Ett mål var att se hur olika provslag i omgivningen av Studsvik fungerar som indikatorer för den uppmätta utsläppta radioaktiviteten.

• 2014:54 Technical Note, Further Modelling Comparison of Simple Reference Biosphere Models with the LDF Modelling Approach – Main Review Phase

  This Technical Note describes further use of simple reference biosphere models for SSM’s review of the Landscape Dose Factor (LDF) approach adopted by SKB in the SR‑Site safety assessment for the proposed final disposal of spent nuclear fuel at the Forsmark site. Simple biosphere models for the Forsmark site under temperate climate conditions were previously developed for SSM’s review and are...

• 2014:58 Technical Note, Rock Mechanics - Assessing probability and extent of blind faults and fault-end growth around the KBS-3 repository at Forsmark – Main Review Phase

  To get a general understanding of the stability conditions of the fault and deformation zone inventory at Forsmark a reactivation potential analysis was carried out. At present-day stress conditions the deformation zones are stable and show no large deformations or detected seismicity. Any changes in stress, and in particular increase of differential stress on deformation zones, might cause...

• 2014:55 Technical Note, Further Reproduction of SKB’s Calculation Cases and Independent

  Som en del av säkerhetsanalysen SR-Site presenterar SKB modellresultat som illustrerar kapseln och buffertens säkerhetsfunktioner. I var och en av de fem beräkningsfallen är delar av kapsel och/eller buffert frånvarande i modellen av slutförvarssystemet. Modellresultaten jämförs inte med säkerhetskriterier eftersom beräkningsfallen innehåller...

• 2014:59 Technical Note, Relation between earthquake magnitude, fracture length and fracture shear displacement in the KBS-3 repository at Forsmark – Main Review Phase

  This study addresses one of several scenarios that could impair the physical integrity of the repository of spent nuclear fuel at the Forsmark site. Two sources of threat are: i) events due to thermal loading on the rock mass by the heat from canisters with spent nuclear fuel, and ii) seismic events, i.e. earthquakes, at the nearby deformation zones and zones intersecting the repository area.

• 2014:08 Technical Note, Review of Long-Term Redox Evolution of Groundwater and Potential Influence of Oxygenated Glacial Meltwater in SR-Site

  The Swedish Radiation Safety Authority (SSM) is reviewing an application submitted by the Swedish Nuclear Fuel and Waste Management Company (SKB) in 2011 to construct, possess, and operate a deep geologic repository for spent nuclear fuel at the Forsmark site in the municipality of Östhammar, Sweden. SKB has presented details of its long-term safety assessment, SR-Site, in a main report...

• 2014:11 Technical Note, Radionuclide Solubility Limits in SKB’s Safety Case

  The Swedish Radiation Safety Authority (SSM) is reviewing a license application, which has been submitted by Svensk Kärnbränslehantering AB (SKB), for a spent nuclear fuel repository at Forsmark. This technical note records the findings from a project that forms part of the main phase of SSM’s license application review. The project involved review of reports and independent modelling...

• 2014:10 Technical Note, Rock Mechanics - Confidence of SKB’s models for predicting the occurrence of spalling – Main Review Phase

  This review study is placed in the context of SSM’s Main Review Phase for SKB’s safety assessment SR-Site. The assignment is titled “Rock Mechanics – Confidence of SKB’s models for predicting the occurrence of spalling”. The report presents the authors’ assessment in response to the questions raised by SSM. The review concentrated on two main issues: (1) the analysis of the assumptions made...
