Reducing pressure during strength hydrotests of the primary and secondary circuits

Summary

Kozloduy Nuclear Power Plant is procuring an analysis of whether the pressure used for strength hydrotests of equipment and piping in the primary and secondary circuits of units 5 and 6 can be reduced, and a justification for any reduction. The work covers reactor and steam-generator equipment and associated circuit piping, assessed through deterministic and probabilistic analyses. The single contract includes developing a methodology, carrying out a study and comparative analysis, determining proposed test pressures and preparing a final report; its estimated value is €3,292,476 and its planned duration is 540 days.
