Project Aims

The main objective of the project was to support the Slovak Nuclear Regulatory Authority (UJD) in:

  • Review of upgrading measures foreseen to be implemented at Mochovce NPP (VVER 440/213);
  • Review of safety documentation including Safety Analysis Report on the basis of Western practice;
  • Review of commissioning program and main results of the nuclear tests;
  • Assessment of the overall safety status of the plant.

Project results

Project provided for verification whether the Mochovce NPP design meets criteria as follows:

  • Appropriate defence in depth on all levels;
  • The risk of intolerable consequences for the plant, for humans and for environment is sufficiently low;
  • All factors essentially contributing to safety have been assessed according to applicable current standards and practice.

Project focussed on an in-depth assessment in different areas that involved design, system analysis, accident analysis, and comissioning such as:

  • Integrity of reactor pressure vessel;
  • Integrity of bubble condenser confinement;
  • Ensuring of emergecny core cooling re-circulation via the confinement sump;
  • Vulnerability of emergnecy feedwater supply;
  • Steam generator primary header lid;
  • Reliability of I&C;
  • Scope and methodology of accident analysis;
  • Seismic design;
  • Commissioning.
