Objectives
Maintenance of safety related equipment and if needed the replacement of worn parts is necessary to preserve the adequate safety function of the equipment and to enhance plant availability. Some of the safety related components of the Zaporozhye NPP were running out of the safety margin and parts had to be replaced with approved spare parts.
As part of the Tacis 1994 nuclear safety assistance programme for Ukraine, it was decided to procure urgently needed spare parts required for the maintenance and repair of foreign supplied equipment that had been installed at Zaporozhye NPP in the past.
The NPP operator, together with the On-Site Assistance Consultant prepared a list of urgently needed spare parts and these were divided into 8 lots:
