Reduction of Head Losses in Tunnels by Means of Shotcrete
Head losses in blasted rock tunnels conveying water to hydropower stations often significantly reduces the energy production in the plant. Typical values on the head losses in tunnels...
Active Tunnel Design?A New Concept for Predesign, Contractual Lay-out and Construction Management
Active tunnel Design is a new concept for design, layout of specification and contract, and for construction management of tunnels and underground carverns. Investigations yeild more information...
Discrete Feature Modelling at the Stripa Mine in Sweden: Significance for Hydrologic Modelling of Fractured Rock Masses
The third and final phase of the Stripa Project included a series of characterization efforts, predictions, and validations to determine the viability of discrete-fracture groundwater...
Organic Carbon Input in Shallow Groundwater at ?SP?, Southeastern Sweden
The variation in carbon and oxygen isotopes in calcite fissure fillings and dissolved carbonate from shallow groundwaters has been examined at Aspo, southeastern Sweden. The shallow water...
Management of Spent Nuclear Fuel in Sweden?Experiences and Plans
The principle adopted for the management of spent nuclear fuel from the Swedish reactors is final disposal without reprocessing. During the 1980ies systems and facilities for the transport...
The Swedish Dialogue Project. An Attempt to Explore How Different Actors May Take Part in the Decision Process Related to Disposal of Radioactive Waste
The Swedish Nuclear Power Inspectorate (SKI) has initiated a project, DIALOGUE, which is exploring the possibility to define review procedures for license applications of nuclear waste...
Automatic Calibration of 3D Finite Differences Model Parameters? Application to the Finnsjon Site (Sweden)
Calibration of 3D finite difference model parameters is usually carried out using a noon-automatic 'manual' procedure until observed heads, for instance, are simulated with a sufficient...
Use of Coupled Geochemical and Transport Calculations for Nuclear Waste Problems
The dissolution and migration of radionuclides from a final repository for radioactive waste is complex chemically. The dissolution and release rates depend on the chemistry and on advective...
The Technology of X2000?ABB's High Speed Tilting Train
The X2000 High Speed Tilting Train was developed by Asea Brown Boveri (ABB) in cooperation with the Swedish State Railways (SJ). The purpose of the project was to reduce trip times on...
Simulation of Large PRT Systems for Swedish Cities
Simulation models have been developed in Sweden to analyze large PRT networks. A new control concept is introduced called `point-synchronous control'. It is a practical way of realizing...
APM Activities in Gothenburg
The Gothenburg Traffic Authority has found that new traffic policy goals are very difficult to achieve with conventional public transport techniques. Two studies on new concepts have been...
Preliminary National Evaluations of CO2 Emission Controls
Under the aegis of the International Energy Agency, several countries have begun making comparable studies of the cost-effectiveness of various measures to reduce emissions of carbon dioxide...
Application of Discrete Feature Analysis to Repository Characterization
Rock mass heterogeneity plays an important role in the hydrologic and mechanical behavior of radioactive waste repositories. This heterogeneity is, in turn, strongly influenced by the...
Communicating Confidence and Creating Credibility
To educate the general public and their opinion leaders in radioactive waste management is imperative to reach the decision where to site the Swedish repository for spent nuclear fuel....
Conclusions from Project-90 With Regard to a Regulatory Framework
A five year performance assessment program, Project-90 [1], has been concluded by the Swedish Nuclear Power Inspectorate, SKI. The project was defined to develop independent assessment...
The Integrated Performance Assessment in SKI Project-90
The SKI Project-90 is a performance assessment of a hypothetical repository system with KBS-3 features in crystalline rock. A large part of the effort has been to identify and characterize...
The SKI Regulatory Strategy and Performance Assessment Program in Relation to Final Disposal of Spent Nuclear Fuel and High Level Radioactive Waste
Important steps are planned to be made during the 1990s in the Swedish program for final disposal of spent nuclear fuel and high level radioactive wastes. Site selection will be done in...
Drill-Back Studies Examine Fractured, Heated Rock
To investigate the effects of heating on the mineralogical, geochemical, and mechanical properties of rock by high-level radioactive waste, cores are being examined from holes penetrating...
