Session 2015-2016


Place of Visit: NPCIL, Rawatbhata

Students : VIEEE Branch Students

Date: 24.10.2015

Faculty Coordinator: Mr. Dhiraj Singh, Asst. Professor


The Industrial visit for students of VIEEE Branch was organized as a part of Student – Industry Interaction program. This visit was of one day. Students visited the Nuclear Power Corporation of India Limited, Rawatbhata.

Nuclear Power Corporation of India Limited (NPCIL) is a Public Sector Enterprise under the administrative control of the Department of Atomic Energy (DAE),Government of India. The Company was registered as a Public Limited Company under the Companies Act, 1956 in September 1987 with the objectives of operating atomic power plants and implementing atomic power projects for generation of electricity in pursuance of the schemes and programmes of the Government of India under the Atomic Energy Act, 1962. NPCIL also has equity participation in BHAVINI, another PSU of Department of Atomic Energy (DAE) which implements Fast Breeder Reactors programme in the country. Visit started with a presentation on NPCIL. In which they ellaborated that, NPCIL is responsible for design, construction, commissioning and operation of nuclear power reactors. NPCIL is a MoU signing, profit making and dividend paying company with the highest level of credit rating (AAA rating by CRISIL and CARE). NPCIL is presently operating 21 nuclear power reactors with an installed capacity of 5780 MW. The reactor fleet comprises two Boiling Water Reactors (BWRs) and 18 Pressurised Heavy Water Reactors (PHWRs) including one 100 MW PHWR at Rajasthan which is owned by DAE, Government of India. Currently NPCIL has five reactors under various stages of construction/commissioning totaling 3800 MW capacity. NPCIL, Rawatbhata consist of 6 units (100MW,200MW and 4*220MW PHWRs), 2 units are under construction(2*700MW). Student visited 5 th unit over their, where they got to know the working process of Nuclear Power Plant.

They brief students about following points:

Operating Performance

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 two coffee table books viz. “Our Flying Guests” on the birds found within and around all the Indian nuclear power plants and "7 Edens and 70 Fairies" on the butterflies of Indian NPPs.

Biodiversity Conservation

Highest ever nuclear power gross generation of 37,835 MUs was achieved in the year 2014-15. NPCIL has set several records in the safe operation of nuclear power plants. For instance, ten reactors of the company have run non-stop for more than one year. Among them, the unit-5 of Rajasthan Atomic Power Station was operated for more than 765 days non-stop and became world's second longest run nuclear power reactor. The Unit-2 of Tarapur Atomic Power Station has run continuously for 590 days, another notable achievement. So far NPCIL has consistently maintained overall availability factor of reactors above 80% for several years and in the year 2014-15 it was 88%.

Safety Performance

NPCIL has achieved about 420 reactor 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: 2004 and IS-18001: 2007 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 and National Safety Council-Mumbai.
