Nevertheless, if URENCO does not abandon the development of the site in Gronau, then the following activities will be performed on the site in Gronau until 2035 - Table 2.8. Activities to implement the development strategy of URENCO Deutschland GmbH (UD) in the period of up to 2035 (Option, if Gronau site development doesn t stop) Table 2.8 Plant UTA-1 UTA-2 Development (forecast) Option 1 UTA-1 plant modernization. Option 2 - Termination of UTA-1 plant operation by 2035. Decommissioning (decontamination and dismantling) after 2035. The project of the UTA-2 plant provided for construction and placing into service of the plant two phases [8]. According to the UTA-2 plant project the first and second phases will have a shared UF 6 Handling Area. The project provided for the TC-21 technology to be used in the first phase of the UTA-2 plant, the TC-12 technology in the second phase. The first phase of the UTA-2 plant (made operational in 2008-2011) is based on the GC TC-21 technology. UTA-2 plant first phase nominal operation capacity is 2.85 mln. SWU. UTA-2 plant second phase nominal operation capacity is 1.15 mln. SWU. Option 1 - UTA-1 plant modernization. UTA-2 second phase will be not demanded until 2035. UTA-2 plant second phase will be not in demand until 2035. Option 2 - Termination of UTA-1 plant operation by 2035. Decommissioning (decontamination and dismantling) after 2035. Construction and commissioning UTA-2 plant second phase started from 2021. IBR TM 46
