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

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.

INDIA INSTALLED CAPACITY & % SHARE BY VARIOUS SOURCES

coal,62%hydro,16%

wind,12%

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%

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

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

NUCLEAR POWER PLANT LAYOUT (PHWR)

COMPONENT OF POWER PLANT

1. Reactor Building2. Calandria 3. Steam generator 4. Turbine5. Heat Exchanger6. Moderator 7. Cooling tower 8. Waste Management plant

REACTOR BUILDING

COMPONENTS OF REACTOR BUILDING Calandria Control mechanism Heat exchanger Pumps Moderator

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 .

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

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 supplyHeat of primary is transferred to

secondary supply

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*110MW2. 1*200MW3. 4*220MW

TURBINE

It converts kinetic energy of steam into mechanical energy

Rated speed: 3000 rpm Two turbine are used High pressure turbine Low pressure turbine

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 tower1) Natural draft cooling tower(NDCT)2) Induced draft cooling tower(IDCT)

NATURAL DRAFT COOLING TOWER

INDUCED DRAFT COOLING TOWER

WASTE MANAGEMENT PLANT Here we have 3 types of wastes:-1. Solid waste2. Liquid waste3. Gaseous waste

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
