Q. Discuss the significance of RAPS-5 as a nuclear energy milestone in India. (100 words)

RAPSRawatbhatta Atomic Power Station
RecordContinuous Operation for 765 days. Proves that India can generate nuke power in safe and reliable manner.
TechnologyPressurised Heavy Water Reactor ( Indigenous) by NAPCIL.
FuelNatural Uranium
CoolingHeavy Water
ModeratorHeavy Water
Supplies Power toRajasthan, Uttar Pradesh, Delhi, Haryana, Punjab, Jammu & Kashmir, Himachal Pradesh, Chandigarh and Uttrakhand.
Number of reactors
  • 6 constructed
  • 2 reactors under construction
  • Largest number of reactors in a single site.

Kudankulam: 1000 MW mark

Brief Profile of Kudankulam Plant
TechnologyVoda Voda Energo Reactor (VVER)= water cooled, water moderated energy reactor.
  • Atomstroyexports, Russia supplied both uranium and the the VVER technology.
  • Atomstroyexport is a subsidiary of Russian PSU Rosatom.
Typelight water reactor
Sub-TypePressurized water reactor
  1. Tamil Nadu
  2. Karnataka
  3. Kerala
  4. Puducherry

NPCIL will sell electricity to them at Rs.3.50 per unit. All the unallocated electricity belongs to Union government.


Timeline of Nuclear reactors in India
1969Tarapur, with US help.
2002Kudankulam construction begins
2011People’s Movement Against Nuclear Energy (PMANE) begins protests against Kudankulam project.
2013Attained critical capacity. This is India’s 21st reactor.
2014, May
  • Protest completes 1000 days.
  • Supreme court rejects their plea to appoint another safety Committee for Kudankulam
2014, June
  • Tamilnadu becomes first state to have two operational nuke plants viz. Kudankulam and Kalpakkam.
  • Kudankulam becomes first nuclear plant to attain 1000MW capacity
  • Other desi nuke reactors have capacity of 700MW only.
  • Tata Mundra Thermal plant 800MW


States with highest nuclear energy (October 2013 data)
State rankNuke power (MW)
  1. Tamilnadu
  1. Maharashtra
  1. Rajasthan
  1. Gujarat, Karnataka and Uttar Pradhesh
each with 880

Reasons for delay in reaching 1000MW mark:

  1. So far India used Pressurized Heavy Water reactor technology. But Kudankulam uses Light water reactor technology. So NPCIL engineers had to buy coaching material to learn how to use new technology.
  2. After Fukushima incident, NPCIL had to build additional safety measures.
  3. Anti-Kudankulam protests, court cases.

Kudankulam nuke plant: SC rejects plea to appoint panel

In 2013

  • Anti-nuclear activist G. Sundarrajan filed petition in Supreme court, alleging that Atomic energy regulatory board (AERB) made haste in clearing the Kudankulam plant in Tamilnadu.
  • Supreme court permitted construction of Kudankulam plant, but gave strict guidelines for disaster management, environmental protection, nuclear leakage, regular inspection @3 months interval etc.

In 2014, May

  • G. Sudar Rajan again went to SC, demanding a committee under Ex-AERB chief A.Gopalakrishnan to supervise the plant.
  • But Supreme Court on Thursday rejected the plea to appoint any expert team- AERB, NPCIL sufficient. It is not necessary to appoint SITs and Committees everywhere.
