ACKNOWLEDGEMENT
We are gladly thankful to Head of the Department
Prof. H. H. GAJERA(Civil Engineering) for providing such
great opportunities to learn something new and innovative and
our faculties who gave us a great guidance regarding training
and instructed us the importance of training in civil field. So
we decided to take visit in KAKRAPAR Atomic power
station-NPCIL located in Mandavi Taluka of Surat District for
about 65 students of 6th & 4th semester .

GENERAL INFORMATION
The Kakrapar atomic power station (KAPS-1&2) is
the fifth nuclear power station near Mandvi taluka of surat
district, Gujarat in India. There is the 2 units power plant
producing 220 MW of electricity each, a large atomic energy
producing project involving the construction of a series of
large reactor building, turbine building and other common
facilities. The project took form in 1992-93 as part of a
development scheme to increase usage of non-conventional
energy source and produce hydroelectricity.
The Kakrapar atomic power station advances with
the two more units 700 Mwe which are under construction
and are likely to be under operation at about 2019-20.

PURPOSE OF VISIT
Our main purpose for this visit is to be familiar with
industrial environment and to get practical knowledge of
atomic energy producing plant. With the extinction in the
energy resources it had been a compulsory purpose to figure
out an alternative energy source which should be economical,
Eco-friendly, safe and efficient.
The other reason was to figure out the reasons of leakage
and to carry out safety measures as a civil engineers.
Some other purpose was to know about the solutions of
the atomic waste disposal.

WHAT WE LEARN?
On 2nd April 2016 (Saturday), we reached at
KAKRAPAR atomic power station (KAPS). We reached
inside power plant at 10:30 am.
We firstly got the overall technical information at
Training center by the expert technician Mr. Shailesh Kumar,
who have experience of 15 years at Kakrapar atomic power
station-NPCIL & Mr. Paurush Kumar .
The plant consists of following components
1. Reactor Building (RB) – 1 & 2
2. Turbine Building (TB) – 1 & 2
3. Service Building
4. CW Pump House
5. Natural Draft Cooling Tower (NDCT) – 1 & 2
6. Induced Draft Cooling Tower (IDCT) – 1 & 2
7. Demineraliser Plant (DM Plant)
8. 220 KV Switch yard
9. Stack
10. Canteen Building
11. Administrative Building
12. Ware House

1. Reactor building (RB) – 1 & 2 :-
It consists of
a. Calandria
b. Primary Heat Transport Pump and Moderator System
c. Control and Shutdown
a. Calandria :-
This contains Uranium-236 R as a fuel integral with end shields.
b. Primary Heat Transport Pump and Moderator System:-
Primary heat transport system circulates heavy
water through the fuel in the coolant channels to extract the
heat generated in the fuel by fission.

c. Control and Shutdown :-
Power generation is controlled and adjusted
through reactivity regulating system. It consists two shutdown
systems, primary shutdown system consists 14 nos. of
mechanical rods & secondary comprises of 12 nos. of liquid
poison tubes.
“Reactor building consists of two walls at 2.0 m distance
apart, primary containment made up of pre-stressed concrete
as a cylindrical shell and secondary made up of reinforced
concrete. Primary Containment has 40m outer diameter while
Secondary has 46m outer diameter.”
2. Turbine Building (TB) – 1 & 2:-
The heat energy from reactor is transferred by PHT
systems to light water in steam generators. Steam with 40
kg/sq.cm and temperature of 250 Celsius is supplied to the
turbo generator through main steam headers.
There are two types of turbines are used in plant:
a. impulse turbines
b. reaction turbines

3. Service Building:-
It includes new fuel room, spent fuel storage bay,
light water auxiliary cooling equipment, chemical laboratory,
ventilation system and access to the reactor building.
4. Natural Draft Cooling Tower (NDCT) – 1 & 2:-
“It is naturally drawn cooling tower. It possess a
typical structure with large base for strength & roof
comparatively smaller for venturrie effect”.
5. Induced Draft Cooling Tower (IDCT) – 1 & 2:-
It is mechanically drawn cooling tower with smaller
height as compare to NDCT. In this cooling tower water is
splited into droplets for decreasing it's temperature.
6. Demineraliser Plant (DM Plant):-
This plant demineralises water for controlling its
conductivity and protecting the pipe from cavitation.
Pipes are made from NIOBIUM for controlling ductile
to brittle transition.

7. 220 KV Switchyard:-
The switchyard has 13 bays. Each bay contains isolators ,
current transformers, lighting arrestors, wave traps and
capacitor voltage transformer.
Station electric power is evacuated through seven
number of 220KV lines connecting to the Gujarat electricity
board grid network, two lines to Haldarva (near Bharuch), two
to Vapi, two to Vav (near Surat) and one to Ukai Thermal
power station (interconnection).
