Placement Scenarios

This set of pages presents those options that have been retained during the first step of the Avoid-Reduce-Compensate (fr. Éviter-Réduire-Compenser) process as candidates for further optimisation and those ones that are selected for presentation of the design of the research infrastructure.

Comparison of classes

Tow main classes have been identified for the development of feasible scenarios: PB17 and PB19.

A comparison of their merits and drawbacks helps to come to the development of one single, preferred scenario.
