What Will be the Engineered Barriers for Deep Disposal of High Level Radioactive Wastes in the Future?
Two sealing approaches are currently being developed in France for deep geological disposal of high-level wastes. One is based on the use of swelling clay in order to restore the initial...

Near-Field Modelling for the Safety Assessment of French High-Level Waste Repositories
In assessing the safety of a French high-level waste repository, the fluxes of radionuclides released by the near-field into the geosphere are modelled by the CONDIMENT source code. This...

Optimization Method for Dimensioning a Geological HLW Waste Repository
This method was developed by the CEA to optimize the dimensions of a geological repository by taking account of technical and economic parameters. It involves optimizing radioactive waste...

The International Stripa Project: Technology Transfer From Cooperation in Scientific and Technological Research on Nuclear Waste Disposal
The Nuclear Energy Agency of the Organization for Economic Cooperation and Development (OECD/NEA) sponsors the International Stripa Project. The Stripa Project is open to participation...

The Status of the Site Characterization and Validation Program in Phase III of the OECD/NEA Stripa Project
In 1980, the International Stripa Project was organized under the aegis of the OECD Nuclear Energy Agency for the purpose of conducting research, at the Stripa mine in Sweden, related...

Sellafield?From High Level Notoriety to Intermediate Acceptance
After a highly publicised accident at Sellafield, involving radioactive pollution, a period of continuous adverse media coverage eroded public confidence in the plant and its operators,...

Spent Fuel and High-Level Waste Management in Selected Countries: Trends and Issues
This paper contains descriptions of the major parameters and plans for management of spent nuclear fuel and high-level radioactive wastes in Belgium, Canada, France, the Federal Republic...

Analysis of RADTRAN Transportation Model
The RADTRAN computer model, used to estimate the risks of transporting waste to a high-level repository, is critically reviewed. Ignoring high consequence accidents, human error, sabotage,...

Effect of Minor Actinide Removal From Fission Products Before Vitrification on the Radiological Impact of a High Level Waste Deep Repository
The topic of this work is to assess the effect of minor actinide (Cm, Am, Np) removal from fission products before vitrification on the radiological impact of a vitrified waste geological...

The Source Term for HLW Disposal in the European Communities' R&D Programme
During the last five years, the EC's research programme on radioactive waste has focused much of its investigation in the field of HLW management on the source term for geologic...

Research for Final Disposal of Unreprocessed Spent Nuclear Fuel in Sweden
The second Swedish programme on research, development and demonstration in the nuclear radioactive waste management area was submitted by SKB to the Swedish National Board for Spent Nuclear...

Status of Site Investigations for Spent Fuel Repository in Finland
TVO's site programme aims at selection of a repository site for spent fuel by the end of 2000. A repository is planned to be constructed in the 2010's and commissioned...

High Level Waste Management at Sellafield
Reprocessing of irradiated nuclear fuel has been carried out at Sellafield since 1952, when reprocessing of fuel from the original UK air-cooled reactors began. In 1964 a second reprocessing...

Influence of High Burn Up Nuclear Fuel and MOX on the High Level Reprocessing Waste Management
This paper compares characteristics of high level waste issued from the reprocessing of high burn up fuel (HTC) and mixed oxide (U-Pu)O2 fuel (MOX)...

Real-Time Optimized Control of a Water Distribution System
The paper presents the design of a fully automated real-time computer control scheme for least cost operation of a water distribution system. The scheme includes modules for optimized...

An Expert System for Control Curve Evaluation During Drought
This paper presents ongoing research into the automation of control curve generation and the development of an expert system for reservoir management for North West Water of Warrington,...

Estimating Earthquake Hazard of Municipal Water Systems
This paper uses the City of Memphis as a case study to present the seismic hazard evaluation of a municipal water delivery system. The horizontal peak bedrock accelerations resulting from...

A User-Friendly Capital Programming Tool for Highway Maintenance Districts
The Roads and Waterways Administration of Finland is developing a microcomputer system, called the Project Analysis System (PAS), to help district engineers in their annual preparation...

An Eulerian-Lagrangian Model for Sediment Transport in Estuaries
We describe a new depth-averaged numerical model for the simulation of the fate of sediments in estuaries. The model, denoted ELAsed, includes the following distinctive characteristics:...

Two-dimensional Modelling of the Bristol Channel, UK
A two-dimensional depth-averaged numerical hydrodynamic model of the Bristol Channel and Severn Estuary has been developed to investigate the effects on water quality of existing and new...
