New tooling at Russia's Rostov NPP cuts filter maintenance time to two days

On August 28, local time, Russia's Rostov Nuclear Power Plant announced that its engineering and technical personnel have developed and put into operation a set of specialized tooling for the maintenance of filters in the ball-type pre-filter system (SShO) of the turbine hall, significantly reducing the time required for equipment maintenance preparation and overhaul. Rostov NPP is part of Rosenergoatom, the electric power division of Russia's State Atomic Energy Corporation (Rosatom). The filters targeted by this improvement weigh over one ton each and require crane assistance for movement, but the existing fixed cranes on site cannot directly cover the equipment locations. To address this issue, the maintenance preparation and implementation department...

Welding of main circulation pipeline completed for Unit 2 of Turkey's Akkuyu NPP

On August 27, welding of the main circulation pipeline was completed for Unit 2 of Turkey's Akkuyu Nuclear Power Plant. The pipeline connects the reactor, steam generators, and main circulation pumps, and is one of the key components forming the primary circuit system of the reactor facility. The welding work lasted 73 days and involved welding 32 pipe joints. Engineering technicians, welders, fitters, pipe cutters, non-destructive testing personnel, heat treatment personnel, and quality inspection personnel participated in the relevant operations. During construction, each process step proceeded according to the established technological workflow, and welded joints had to pass inspection before moving to the next stage. According to reports, all welded joints underwent high-temperature heat treatment to relieve internal stress in the metal and ensure compliance with design performance requirements.
