Pre-project activities are in progress in these projects.


Operating Performance

Generation by all units of NPCIL in the financial year (FY) 2022-23 was 45855 MUs. In addition 1127 MU of infirm power was also generated during the year. NPCIL has set several records in the safe operation of nuclear power plants. So far NPCIL has consistently maintained overall availability factor of reactors above 80% for several years.


Safety Performance

NPCIL has more than 53 years of experience in safe operation of nuclear power plants, with motto of ‘Safety first and Production next'. The Environmental Management System (EMS) and Occupational Health and Safety Management System (OHSMS) as per ISO-14001 and IS-18001 respectively are maintained at all the stations. By following the principle of ALARA (As Low As Reasonably Achievable) and maintaining the highest standards of safety within the Nuclear Power Plants (NPPs), the occupational exposures of employees of the company at various NPPs are maintained well below the values specified by the regulator, Atomic Energy Regulatory Board (AERB). The environmental releases of radioactive effluents from NPPs are maintained significantly low (average less than 1% of the limits specified by AERB). NPCIL contributed in enhancing safety & reliability of nuclear power plants globally through its active participants in World Association of Nuclear Operators (WANO), Candu Owners Group (COG), IAEA and other international organizations. NPCIL units have received several safety awards from various national agencies like AERB, NSCI, Gujarat Safety Council, National Safety Council-Mumbai and DGFASLI.


Biodiversity Conservation

NPCIL has voluntarily taken up Environment Stewardship Programme (ESP), besides fulfilling regulatory and statutory requirements. The programme focuses on the scientific study of bio-diversity, particularly avifauna, within and around Exclusion Zones (EZs) of Indian nuclear power plants for the conservation and improvement of habitat in association with nature conservation institutions. As a part of ESP, the company has published five coffee table books viz. “Our Flying Guests” on the birds found within and around all the Indian nuclear power plants, "7 Edens and 70 Fairies" on the butterflies around the Indian NPPs and "The Realms of Flowers" a book on the flowers of Indian NPPs, “Fliers of Our Courtyards” another book on birds found in and around the Indian NPPS and “100 Lives Around Us” on biodiversity around the Kudankulam Nuclear Power Plant.


Public Outreach Programme

Recognising the need of reaching out to people around its sites and sharing the information on nuclear power to generate correct perspective about nuclear power, NPCIL scaled up its Public Awareness programmes in a structured manner using a multipronged approach. Through several modes of communication, dissemination of accurate information on nuclear power to different target groups is being done regularly.
