From May 18, within the framework of ISF-2 integrated testing with dummies it is scheduled to carry out the primary procedure qualification of welding technique which will be used for DWC handling.

Simultaneously with ISF-2 integrated Testing with dummies, the operational trial of process video surveillance system and process control and monitoring system are carried out.

During the subsequent two stages of ISF-2 integrated Testing with SFA dummies it is planned to conduct the trials associated with liquid and solid waste management systems, “hot cell” ventilation system. Moreover, the maintainability of “hot cell” equipment will be checked. In the course of these operations, an additional crane trolley of the main crane will be used in Room 501.
