Dukovany NPP – Pressure Reduction in Gas Storage Tanks

The purpose of the project implemented for ČEZ, a.s. is the installation of a return pipeline with electrical valves controlled from MCR (main control room) and ECR (emergency control room) from each gas storage tank to enable the return of the content of these gas storage tanks to the air-tight zone. The goal is to enable the use of the content of gas storage tanks in dealing with design extension accidents. As part of the work, a new pipeline will be installed, including shut-off valves and non-return valves, control of valves from MCR and ECR, indication of valve statuses, indication of vacuum in the hermetic box obtained from the measurement of the PAMS system will be put into operation. For the electrical part, the power supply, control and indication of the position of the new shut-off valves will be implemented.

The scope of supply includes the preparation of all design documentation and the project implementation. The project is implemented in five sub-units. It started in 2021 and is scheduled to be completed in 2024.
