AUMA has been selected to supply 1,900 electric actuators to aid automation at Mochovce NPP – an example of one of the actuators supplied is shown in the foreground

AUMA’s ability to supply products to meet the requirements of inside and outside containment was key to the company achieving approved actuator contractor status for Mochovce NPP in Slovakia. The order is significant for the manufacturer and global supplier of electric actuators as 1,900 units will be commissioned as part of reconstruction of the plant’s third and fourth units.

Located close to the towns of Nitra and Levice on the site of the former village of Mochovce, the existing reactors are both 470 MW. The additional two units that will be automated with the support of AUMA actuators will achieve an annual total of 6,000 Gwh of electricity.

AUMA was put forward by the instrumentation and DCS contractor Areva-Siemes who have overseen the supply to date of 657 actuators.

Products supplied for valve control at the plant’s new unit are the AUMA SAI inside containment actuator, SAN device for outside containment and the company’s standard SG product. All actuators conform to AUMA’s modular design construction which ensures ease of installation and upgrades.
