• 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...

• 2012:67 Technical Note, Hydrogeological modelling of the Forsmark site

  A modelling study has been conducted using discrete-fracture network (DFN) models in combination with discrete-feature hydrogeological modelling methods for representation of other potentially conductive features such as the disturbed zone around repository tunnels. The principal results consist of hydraulic and transport property estimates for discrete-fracture network (DFN) models on block...

• 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...

• 2014:07 Technical Note, Review of the geological mapping and geophysical measurement techniques for the determination of critical properties around deposition holes -Main Review Phase

  This Technical Note reports the findings of a detailed evaluation of the geological and geophysical methods proposed by SKB with respect to their ability, resolution, performance, reliability and robustness to measure the geomechanical parameters critical for determining deposition hole acceptability during repository operation. Addressed are specific questions focusing on the detection of...

• 2014:05 Technical Note, Assessment of flows to deposition holes – Main Review Phase

  SKB’s conceptual model for flow through the fractured rock at Forsmark is based on a division between highly fractured deformation zones (described in terms of deterministic geometry), and the more sparsely fractured rock (described in terms of statistical geometry). The model for the highly fractured deformation zones includes several assumptions that are not strongly supported by data,...

• 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...

• 2013:33 Technical Note, Seismology – Frequencies and mechanisms. -Initial review phase

  The Swedish Radiation Safety Authority (SSM) reviews the Swedish Nuclear Fuel Company’s (SKB) applications under the Act on Nuclear Activities (SFS 1984:3) for the construction and operation of a repository for spent nuclear fuel and for an encapsulation facility. As part of the review, SSM commissions consultants to carry out work in order to obtain information on specific issues. The...

• 2012:53 Technical Note, Review of Engineering Geology and Rock Engineering aspects of the operation and closure of a KBS-3 repository at the Forsmark site – Initial Review Phase

  SRK Consulting (UK) Limited (SRK) has reviewed the Engineering Geology and Rock Engineering aspects of the operation and closure of a KBS-3 repository at the Forsmark site in Sweden. The review assignment is part of a Swedish Radiation Safety Authority (SSM) Initial Review Phase. The review was carried out by David Saiang (PhD) on behalf of SRK. Therefore some of the views expressed in the...

• 2012:57 Technical Note, Shear movement of near-field rock due to large earthquakes

  This technical note is part of a set of reviews for Swedish Radiation Safety Authority (SSM) by external experts to assist with the Initial Review Phase. The overall goal of the Initial Review Phase is for SSM to achieve a broad coverage of the information provided in SR-Site and its supporting references and in particular to identify where complementary information or clarifications need to...

• 2012:52 Technical Note, Shear movement of near-field rock due to large earthquakes

  The review assignment concentrates on the possible impact of large earthquakes on the shear deformation of large fractures in the repository volume. For this purpose a general review of some of SKB‘s top-level reports was carried out. The reports draw a generally consistent and to a considerable extend comprehensive picture of the potential impact on the repository integrity in case of the...
