Probabilistic Analysis of the Ghonem and Dore Data
A two-state Markov process model for fatigue crack growth is utilized with experimental fatigue crack growth data reported by H. Ghonem and S. Dore to study the effect of stress ratio...

Probabilistic Traffic Load Models and Extreme Loads on a Bridge
This paper contains a summary of the intensive traffic measurements collected in France and Europe, and of the probabilistic distributions adopted for the main parameters. The evaluation...

Role of Waste Packages in the Safety of a High Level Waste Repository in a Deep Geological Formation
The safety of a radioactive waste disposal facility lays on the three following barriers placed between the radioactive materials and the biosphere: the waste package, the engineered barriers,...

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...

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...

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...

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)...

Public/Private Partnerships: Recent Trends in France
The revival of liberal ideas provided rich soil in France for the growth of private/public partnerships in financing urban mobility services. This partnership is based on one of the following...

Public/Private Partnership?The French Example: The Toulouse Metro Project
Faced with a continuing great demand for urban public transportation, the French public authorities have, for several years, been looking for new sources of financing. Concerning urban...

Overhauling and Opening to Traffic of a Toll Tunnel in Marseilles (France)
The city of Marseilles called for bids for overhauling and opening to traffic an old unused railway tunnel, under the very center of the city. The tender scheme was a concession. The paper...

An Example of Privately Funded Project
The paper discusses the proposal of the Syndicat des Transports Parisiens, the local authority in charge of Public Transports in the Paris region, to ask private firms to implement without...

Use of Linear Programming for Hydraulics Problems
Water is becoming a more and more precious commodity worldwide with each passing day. At the same time, the optimum and most productive solutions to water control and utilization are becoming...

Seismic Isolation of Nuclear Plants: A World Overview
The French were first to apply seismic isolation to the design of nuclear structures. Two large Pressurized Water Reactor plants (PWR) were isolated; the two unit Koeberg station in South...

Optimal Control of the West Parisian Area Water Supply Network
The West Parisian Area regional office of Lyonnaise des Eaux has been equipped with computer-aided optimal decision-making software, using daily water demand forecasts. This tool calculates...

Computerized Operation of Water and Urban Networks: From Digital Mapping to Integrated Information Systems
