Objective
With this project training on NDT equipment should be given.
The equipment’s origin was Intercontrole, France. (The NDT-equipment for which the training was performed, has been financed from other than Tacis funding).

Background
The accident at the Chernobyl Nuclear Power Plant in Ukraine in April 1986 demonstrated the need for adequate radiation early warning systems that allow authorities to take appropriate and timely actions in the event of a major radiological accident.
Objective
This project on Reactor Vessel embrittlement was identified in the very early stage (1991) of the TACIS and PHARE programmes for nuclear safety as a main topic.
Objective
The objective of the project was to develop a residual life time diagnostic system based both on existing Russian developments and on the Contractor’s experience. This system was to be implemented on operating VVER-NPPs.
