Location: DE - Germany
The average burnup 48 MWd/kg heavy metal around year 2000 has been assumed representative for the lifetime of the modeled plant. The average burnup corresponds to an average enrichment of 3.8% U235 for fresh uranium fuel elements. The utilisation factor for the infrastructure is the inverse of the total net electricity delivered in 40 years lifetime; the production of the Swiss BWR has been adjusted by the average country specific capacity factors for the period 1997 to 2002 with consideration of the different contributions from the two classes 1000 MW and 1300 MW; for this purpose, the infrastructure of the 1000 MW class has been increased by a factor of 1.2 to represent the plants belonging to the 1300 MW class and then the two contributions have been weighted by the energy production shares. Material requirements have been extrapolated from the Swiss BWR by the ratio of the capacity factors. The transport requirements are calculated with the standard distances for chemical and diesel requirements and assumed specific distances for fuel recharge and radioactive waste. Radioactive emission species to air and water are averages weighted by energy of the emissions from 1000 MW and 1300 MW BWRs in the period 1995 - 1999. The radioactive water emissions have been inputted to the most detailed available emission species; the difference between the "total beta-gamma (excluding H-3)" given by the reference and the sum of the detailed species has been inputted as "Radioactive species, Nuclides, unspecified". The radioactive waste streams are modeled according to share: spent fuel to reprocessing (40%) and conditioning (60%) (approximate share based on available information on the amount and fate of the total arisings of spent fuel from operational German nuclear power reactors); and, contaminated waste from dismantling. The latter stream has been recalculated by the ratio of the utilisation factors for infrastructure.

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.
