In service inspection of primary circuit components (Continuation PH1.02/94)


Beneficiary Organization Details
Dukovany NPP (Czech Republic)
Project Aims
The objective of the present continuation project was to provide a level of quality and effectiveness of In-Service Inspection equivalent to the level of European practice. For this reason it was necessary to complete the ISI-programme for VVER 440-213 type primary circuit components of high safety concern that have not been covered by the project Phare 1.02/94.
The project consisted in the improvement of ISI for three additional inspection areas, suggested and justified by the main Beneficiary:

  • Main circulation pump (MCP) shell to elbow weld;
  • Longitudinal weld of MCP elbow;
  • Pressurizer nozzle to transition nozzle dissimilar weld;

Project Results
The project was completed into the same phases as the original project to enable a sufficient level of integration:

  • Evaluate ISI effectiveness for selected inspection area;
  • Provide an additional development programme and planning;
  • Supply of test assemblies and calibration blocks;
  • Supply of inspection procedures;
  • Define inspection qualification for all the inspection areas;
  • Perform inspection qualification for at least one inspection area;
  • Evaluate the improved ISI effectiveness;
  • Present the proposed activities to the reviewers (ENIQ, AMES, NESC, …) and to the local Safety Authorities.
