Nuclear waste storage - final repository for high level radioactive waste (nuclear waste storage construction)

The activity generating the emissions is nuclear waste storage construction, final repository for high level radioactive waste. The Reference Product is nuclear waste storage, final repository for high level radioactive waste. This is an immobile infrastructure, representing the construction of a nuclear waste storage, final repository for high level radioactive waste. The infrastructure consists of a 5 km long ramp that leads to the approximately 650 m deep and 120 m thick host rock, suitable for approximately 16,000 m3 of waste like conditioned spent fuel (SF), vitrified high level waste (HLW) and intermediate level waste (ILW) repository. The area required for the external facilities of the portal area amounts to a maximum of 300 m × 150 m and is divided into two parts (50:50 split of 22500 m2 each): on the one hand, the administration building, operating building, ventilation building, equipment lock, railroad access road, road access road and, on the other hand, the conditioning and packaging facility (NTB 02-02) - covered in separate modules. A further area take-up originates from the facilities in the shaft head area in the emplacement operation (construction stage 3) and is estimated at 100 m × 100 m (10000 m2), including winding tower with exhaust vents, site office, crew rooms, workshop, transformer station, excavated material depot and equipment/materials hall. Thus, the total area conversion of the repository is approximately 32500 m2 (22500+10000). Of this, 80% (18000+8000=26000 m2) is assumed to be built-up, 20% (4500+2000=6500 m2) is assumed to be grassland. The first part of the area is used over a period of 23 years (8 years of construction and 15 years of operation), the second part during 15 years (operation only). This gives a value of 5.34E+5 m2a for industrial land use and 1.34E+5 m2a for green space. The total demand for buildings is 1.3E+5 m3. The process includes building material and energy requirements for concstruction, land use and decommission. The Reference Product amount is 1. The cut-off classification is allocatable product. The activity type is ordinary transforming activity. Please refer to the ecoinvent documentation for full details: https://ecoquery.ecoinvent.org/3.12/cutoff/dataset/9189/documentation
