This module uses a mix of data, some specific for the URENCO facilities taken from environmental reports, some from literature. Due to extremely limited information on Chinese plants, of somewhat outdated Russian technology, all requirements and emissions are arbitrarily assumed the double of the URENCO module, along the dataset for TENEX. However, the CNNC facility is assumed to consume 170 kWh/SWU (after one reference), which should include all energy uses (electric + thermal, as electric equivalent). The factor for the infrastructure requirement is calculated with annual throughput of 1500 t SWU for 30 years operation. Transport requirements recalculated either using ecoinvent standard distances for Europe (e.g. for chemicals) or given average distances by train from Chinese 2004 statistivcs or own assumptions. This dataset has been developed with the goal to serve a preliminary estimation of the Chinese nuclear chain for the Chinese electricity mix. Hence, it cannot be used for comparisons of centrifuge enrichment among countrie
[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.


The technology used for uranium enrichment with centrifuge process in China is based on a somewhat outdated Russian technology (after information from one source).
