What happens during an OSART mission?

The first day is used for plant access formalities and induction training. In addition, the TL and DTL conduct refreshers training for the team on the OSART programme, the mission schedule, review and evaluation skills, and their expectations of team members. The training also highlights factors unique to the mission and the nuclear power plant and enables the reviewers to begin working together as a team.

On the second day, an entrance meeting with senior plant management, representatives from the nuclear safety regulatory authority and other concerned authorities is held in the morning. The experts then join their plant counterparts. In the afternoon, a plant tour is carried out in several groups, with the aim of covering as many premises as possible and identifying any areas for further investigation.

From the third day to the end of the second week reviewers conduct individual interviews, make observations and discussions with plant counterparts. At daily meetings, all team members share notes and exchange information on facts or concerns identified. Through discussion, the team develops a consensus on emerging issues.

The team leader informs the plant manager daily on the progress made. Opportunities for improvement and areas of outstanding performance are discussed as they emerge. The last days of the mission are reserved for closing any open topics, completing technical notes and discussing them with the plant counterparts. Additionally, each team member drafts a summary of their review area for the technical notes and for an oral presentation at the exit meeting.
