Scientific Officer C & D — Nuclear Power Corporation of India Limited (NPCIL)

My journey at NPCIL began as a Scientific Officer C, where I worked on geotechnical investigations and seismic site evaluation for nuclear power plant projects. I was responsible for planning, supervising, and interpreting subsurface investigations, including borehole exploration, in-situ testing, and laboratory characterization of soils and rock. The work required close coordination with industrial testing agencies and consultants to ensure that all geotechnical data met the stringent quality and safety standards required for nuclear infrastructure.

A major part of my role focused on seismic geotechnics and liquefaction analysis. I worked extensively on evaluating site response and liquefaction potential under earthquake loading conditions using both empirical and analytical methods. This involved collaboration with leading research institutions in India, including IIT Roorkee, IIT Delhi, IIT Bombay, and IISc Bangalore, on advanced geotechnical and seismic analyses for nuclear sites.

I was also involved in generating synthetic ground response spectra for nuclear plant sites using field investigation data, borehole profiles, and site-specific dynamic soil properties obtained through extensive experimental programs. These analyses formed a critical component of seismic design inputs for nuclear facilities and required careful integration of geotechnical, seismological, and structural engineering principles.

In addition to analytical work, I regularly visited project sites to review construction activities and ensure that the designs and engineering specifications developed during analysis and design phases were being implemented correctly in the field. These site visits gave me practical exposure to large-scale infrastructure construction and helped bridge the gap between engineering design and on-site execution.

I worked closely with experimental and industrial partners on specialized soil testing programs, including cyclic and dynamic soil characterization studies. This experience allowed me to contribute to both the research and practical implementation aspects of seismic geotechnical engineering for safety-critical infrastructure.

After my promotion to Scientific Officer D, my responsibilities expanded into the structural analysis and design of civil engineering systems for nuclear power plants. I worked on both static and dynamic analysis of reinforced concrete and steel structures in accordance with AERB safety codes and nuclear design standards. My work included seismic analysis, response spectrum analysis, structural safety assessment, and evaluation of structures subjected to operational and extreme loading conditions.

Another important aspect of my role involved reviewing and validating engineering designs and calculations submitted by external consultants and industry partners. To improve efficiency and consistency in the review process, I developed automation tools and computational workflows to check structural designs, verify code compliance, and streamline engineering validation tasks. These automations significantly reduced manual effort while improving the reliability and traceability of design review processes.

The role required continuous interaction with multidisciplinary teams, including geotechnical engineers, structural engineers, consultants, construction teams, safety experts, and regulatory authorities. Working at NPCIL gave me invaluable experience in applying advanced civil and geotechnical engineering principles to some of the most safety-critical infrastructure systems in the country, while operating at the intersection of research, engineering practice, field implementation, and regulatory compliance.
