This document provides information about the Nuclear Power Corporation of India Limited (NPCIL) and nuclear power plants in India. It discusses that NPCIL was created in 1987 and is responsible for designing, constructing, commissioning and operating nuclear power reactors in India under the Atomic Energy Act. It then provides details about the existing nuclear power plants in India, including their locations and reactor capacities. It also describes the layout and components of a Pressurized Heavy Water Reactor (PHWR) nuclear power plant, with details about the reactor building, calandria, steam generator, turbine, heat exchanger, cooling tower and waste management systems.

2. NUCLEAR POWER CORPORATION OF INDIA LIMITED
 The Nuclear power Corporation Of India Limited (NPCIL) is a government owned corporation
of India based in Mumbai.
 NPCIL is administrated by the Department of Atomic Energy (DAE) , Part of the Ministry of
Science and Technology.
 NPCIL was created in September 1987 as public limited company under the companies act
1956, "with the objective of undertaking the design, construction, operation and maintenance
of the atomic power stations for generation of electricity in pursuance of the schemes and
programmes of the Government of India under the provision of the Atomic Energy Act 1962."
All nuclear power plants operated by the company are certified for ISO-14001 (Environment
Management System).
 NPCIL is responsible for design, construction, commissioning and operation of nuclear power
reactors. Atomic Energy Act, 1962. NPCIL has also equity participation in BHAVINI, an
organization formed for implementation for Fast Breeder Reactors programme in the country

5. RAJASTHAN ATOMIC POWER PLANT
 Rawatbhata remote town in Chittorgarh district about 64 kms from Kota, an
industrial city of Rajasthan.
 The land selected is in between Rana Pratap sagar dam & Gandhi sagar dam at
the right bank of Chambal River.
 The water from the reservoir of the Rana Pratap sagar Dam serves the
requirement of the Nuclear Power Plant.
 There are six PHWR unit. One 100 Mwe, One 200 MWe, Four 220 Mwe unit.
 For employees various colonies are constructed with all the domestic facilities.

6. INDIA INSTALLED CAPACITY & % SHARE BY
VARIOUS SOURCES
coal,62%
hydro,15%

gas+diesel,9%
nuclear,2%
coal hydro wind gas+diesel nuclear
 Present capacity – 2,98,000 MW
 Thermal – 71%
Coal – 62%
Gas – 8.5%
Diesel – 0.5%
 Hydro – 15.5%
 Wind / Renewable – 11.5%
 Nuclear – 2%

7. WHY SHOULD WE USE NUCLEAR ENERGY GENERATION ?
 Comparision of fuel required to generate 1MU electricity

8. COMPARISON OF FUELS
 1 kg fire wood 1 KWh
 1 kg coal 3 KWh
 1 kg oil. 4 KWh
 1 kg uranium. 50,000 KWh
 1 kg plutonium 60,00,000 KWh

REACTION

10. NUCLEAR POWER PLANT LAYOUT (PHWR)

11. COMPONENT OF POWER PLANT
1. Reactor Building
2. Calandria
3. Steam generator
4. Turbine
5. Heat Exchanger
6. Moderator
7. Cooling tower
8. Waste Management plant

12. REACTOR BUILDING

13. COMPONENTS OF REACTOR BUILDING
 Calandria
 Control mechanism
 Heat exchanger
 Pumps
 Moderator

14. CALANDRIA
 It is heart of reactor and form the core of
reactor.
 It consist of:-
 Nuclear fuel
 control rods
 moderator
 It has 306 channels
in these 306 channels we have 12 fuel rod ,
in each fuel rod we have 19 pencil , each
pencil has 12 pellets of fuel .

15. FUEL BUNDLE
 Uranium fuel is used in the form of
Uranium dioxide (U2O).
 Natural Uranium contains-
0.71% U(235)
99.2% U(238)
0.0055% U(234)
 One bundle of fuel contains 19 pencil
(1,612 pencil)
 A fuel rod consist of 13.5 kg of fuel

16. HEAT EXCHANGER
 It has 2 different supply :-
1: D2O
2: DM
The D2O water will act as a Primary
supply
and DM water as a secondary supply
Heat of primary is transferred to
secondary supply

17. STEAM GENERATOR
 Here the K.E of steam is convered
to Electric energy.
It contains a set of turbines which
Are mounted on shaft of the
generator.
In RAPS generators are of :-
1. 1*110MW
2. 1*200MW
3. 4*220MW

18. TURBINE
 It converts kinetic energy of
steam into mechanical energy
 Rated speed: 3000 rpm
 Two turbine are used
 High pressure turbine
 Low pressure turbine

19. COOLING TOWER
 it is a specialized heat exchanger in
which air and water are brought into
direct contact with each other in order to
reduce the water temperature.
 The residual heat is condensed by the
help of cooling tower ‘
 There are two type of cooling tower
1) Natural draft cooling tower(NDCT)
2) Induced draft cooling tower(IDCT)

20. NATURAL DRAFT COOLING TOWER

21. INDUCED DRAFT COOLING TOWER

22. WASTE MANAGEMENT PLANT
 Here we have 3 types of wastes:-
1. Solid waste
2. Liquid waste
3. Gaseous waste

23. ENVIRONMENTAL MONITORING
 Environmental Survey Lab started functioning in the site prior to
commencement of operation of NPP.
 Samples of water, vegetation are periodically analyzed.
 No change is observed from the levels persisted earlier to plant operation.
 Abundant numbers of fishes and crocodiles are found in RAPS lake.
 Many animals have their home at RAPS exclusion zone like monkey,
peacock, deer ,etc.
 Many fruit bearing trees are seen around RAPS site
