State nuclear corporation Rosatom said the mission had been carried out by a team from WANO’s Moscow Centre.
Rosatom said WANO representatives had monitored operators practicing various modes of operation of the plant on a full-scale simulator. They also analysed design and technological documentation and held interviews with operational personnel.
A WANO Moscow Centre spokesman was quoted by Rosatom as saying the technical support mission is an assessment of the operational readiness of the power unit.
