The mission of the AERB is to ensure the use of ionising radiation and nuclear energy in India does not cause undue risk to the health of people and the environment.

Engineering safety studies

Engineering Safety Studies involve safety review, independent analysis and research in the area of structural and seismic studies, reactor thermal hydraulics, fire safety, hydrogen safety, radiological impact assessment etc.

SEISMIC AND STRUCTURAL ANALYSIS

Over the years, several studies have been conducted as part of seismic and structural analysis of NPP components for supporting the regulatory review process. Some of the important studies include:

  • Seismic re-evaluation of NPPs
  • Seismic margin assessment of safety system by analysis and testing
  • Structural integrity assessment of RPV during severe accident
  • Rotor dynamics analysis of primary sodium pump of PFBR
  • Failure probability evaluation of NPP components
