Objectives tree and performance table for nuclear waste management options-1–3.

High-level objectivesCategoryCriteriaOptions
Option-1: decay storage in interim storages for the next 100 yearsOption-2: decay storage and disposal in final repository at the national level after 50 years of decay storageOption-3: regional scenario with transport and disposal into a “multinational” waste repository
