Maintenance of NPP turbogenerators completed ahead of schedule 

ArmInfo. From November 23 to 30, the Armenian Nuclear Power Plant (ANPP) was scheduled to undergo mid-scheduled maintenance on its turbogenerators, which involved  sequential shutdowns. The maintenance was intended to reduce the load  on the power unit to 215 MW, the plant's press service reported.

According to the source, ANPP personnel carried out the maintenance  work diligently and efficiently, allowing them to be completed  approximately three days ahead of schedule. Power supply to the  plant's power unit has been fully restored. The unit is currently  operating at 100% of its thermal capacity (440 MW), ensuring stable  and uninterrupted power generation.

It should be noted that the plant is continuing to implement the  program to extend the service life of its second power unit until  2036. Following the successful completion of the reactor vessel metal  annealing, the Armenian Nuclear Power Plant (ANPP) has entered a new,  strategically important phase: monitoring and supervision of the  reactor vessel metal's condition. This process is a key component in  ensuring the safety, reliability, and long-term operation of Unit 2.  Following the annealing of the reactor vessel metal in 2024, strings  containing sets of test specimens designed for VVER-440 reactors were  installed inside the reactor.

They were installed in designated locations in the reactor shaft to  monitor changes in the reactor metal's properties. The test specimens  have now been removed from the reactor and transported to a  specialized laboratory for detailed studies. The results will be used  to accurately assess the condition of the reactor vessel metal and  its remaining service life for an extended operational period. With  this stage, the Armenian NPP not only strengthens its technical  safety but also confirms that the plant continues to operate in  accordance with the highest international standards, demonstrating  its technological development and responsible approach to safe  operation in the nuclear energy sector.
