The module is oversimplified and shall be considered only as a preliminary description of the storage of low radioactive waste in surface or trench depositories. (The current version of the study has given priority to nuclear depositories for high and intermediate level as well as long-lived radioactive waste.) No leackage is accounted for. Hence, this module may not reflect specific situations. There have been reported leakages from surface depositories, which are continuously monitored. These cases should be rapidly taken care of by removing the leaking object and seal the waste again. A careful modelling of these waste depositories shall be accomplished together with the expected completion of the waste modelling in the next edition of ecoinvent.
[The full documentation of this dataset was originally provided in the corresponding ecoinvent report from the Swiss Centre for Life Cycle Inventories, which is accessible for free to guests and users of ecoinvent version 2 (https://www.ecoinvent.org/login-databases.html). The dataset may subsequently have been subjected to central changes to the database, as described in the respective change report for each new release.]
Undefined unit processes (UPRs) are the unlinked, multi-product activity datasets that form the basis for all of the system models available in the ecoinvent database. This is the way the datasets are obtained and entered into the database by the data providers. These activity datasets are useful for investigating the environmental impacts of a specific activity (gate-to-gate), without regard to its upstream or downstream impacts.
