Traduction de «Near-surface storage » (Anglais → Français) :

In this context, indefinite surface or near-surface storage of spent nuclear fuel that is not to be reprocessed is not considered a suitable or sustainable alternative to disposal.

Long-term indefinite storage at or near the surface for the most hazardous waste, in facilities requiring permanent active measures such as regular maintenance and continuous monitoring and surveillance, is in the long run unsustainable and passes on an unacceptable burden to future generations.

In the meantime, the quantities of spent nuclear fuel and waste held in interim storage at or near the surface continue to grow.

Finally, a Progressive Conservative government would seek to harmonize with the provincial and the territorial governments standards on the storage of products and activities that are permitted near municipal water wells as well as surface-based water supplies.

It also includes any storage reservoirs for the operating medium and the return lines, but not the vehicle's engine (except for the purposes of item 4.1.3) or its drive to the energy source; 1.3.4.1. Energy source means that part of the energy supply which provides the energy in the required form e.g. hydraulic pump, air compressor; 1.3.4.2. Energy reservoir means that part of the energy supply in which the energy provided by the energy source is stored; 1.3.4.3. Storage reservoir means that part of the energy supply in which the operating medium is stored at or near to the atmospheric pressure. 1.4. Steering parameters 1.4.1. Steerin ...[+++]g control effort means the force applied to the steering control in order to steer the vehicle; 1.4.2. Steering time means the period of time from the beginning of the movement of the steering control to the moment at which the steered wheels have reached a specific steering angle; 1.4.3. Steering angle means the angle between the projection of a longitudinal axis of the vehicle and the line of intersection of the wheelplane (being the central plane of the tyre, normal to the spin axis of the wheel) and the road surface; 1.4.4. Steering forces mean all the forces operating in the steering transmission; 1.4.5 Mean steering ratio means the ratio of the angular displacement of the steering control to the mean of the swept steering angle of the steered wheels for a full lock-to-lock turn; 1.4.6. Turning circle means the circle within which are located the projections onto the ground plane of all the points of the vehicle, excluding the external mirrors and the front direction indicators, when the vehicle is driven in a circle; 1.4.7. Nominal radius of steering control means in the case of a steering wheel the shortest dimension from its centre of rotation to the outer edge of the rim. In the case of any other form of control, it means the distance between its centre of rotation and the point at which the steering effort is applied. ...

Among the options being researched are deep geological disposal, partitioning and transmutation (using nuclear reactors, particle accelerators or other new technology to transform long-lived radioactive waste into stable or short-lived isotopes, reducing the volume of waste needing confinement over very long periods of time) and conditioning and long-term near-surface storage.
