A nuclear reactor is a device to initiate and control a sustained nuclear chain reaction. Nuclear reactors are used at nuclear power plants for electricity generation and in propulsion of ships. Heat from nuclear fission is passed to a working fluid (water or gas), which runs through turbines. These either drive a ship's propellers or turn electrical generators. Nuclear generated steam in principle can be used for industrial process heat or for district heating. Some reactors are used to produce isotopes for medical and industrial use, or for production of plutonium for weapons. Some are run only for research. Today there are about 450 nuclear power reactors that are used to generate electricity in about 30 countries around the world.

Light Water Cooled
Nuclear reactors can be classified based on neutron energy, fuel state, fuel material, moderator, type, and geometry. Intermediate reactors have neutron velocities between fast and slow reactors. Fast reactors use high energy neutrons while slow reactors use neutron capture by slow neutrons.

Common reactor types are pressurized water reactors, boiling water reactors, CANDU, gas cooled, and liquid metal reactors. Reactors are used for research, power production, breeding
A nuclear reactor is a device that maintains a self-sustaining nuclear chain reaction to produce controlled nuclear fission. Nuclear reactors were first conceptualized in the 1930s and the first artificial reactor was built in 1942. There are two main types of reactors - research reactors designed to produce radiation beams and power reactors that produce heat primarily to drive power generators. A reactor contains nuclear fuel, a neutron moderator, and a coolant and uses control rods to regulate the fission rate.
The CANDU (Canada Deuterium Uranium) reactor is a Canadian-invented heavy water reactor that uses natural uranium fuel, pressurized heavy water as a coolant and unpressurized heavy water as a moderator. It contains horizontal pressure tubes that circulate the fuel and coolant, transferring heat to steam generators before entering turbines to generate electricity. Unlike other reactors, CANDU uses unenriched uranium and heavy water, allows refueling during operation, and controls reactions using absorber rods inserted into the core.
Fast breeder reactors aim to produce more fissile material than they consume, extending the energy produced from uranium resources. They achieve this through breeding, where fertile uranium-238 is transformed into fissile plutonium-239. Fast breeder reactors also allow for recycling of nuclear waste by burning minor actinides. The Experimental Breeder Reactor I produced the first nuclear electricity in 1951. It was followed by Experimental Breeder Reactor II which operated successfully for over 25 years. Prototype fast reactors have been built up to 250 MWe power levels while commercial plants have reached 1200 MWe like Super Phénix-1 in France. Fast reactors have inherent safety advantages due to their negative temperature

The document describes a pressurized water reactor (PWR). A PWR uses uranium oxide fuel clad in zircaloy and pressurized water as both the coolant and moderator. The heated water from the reactor core transfers its heat to a steam generator to produce steam that drives a turbine and generates electricity. A key component, the pressurizer, maintains the coolant system at a higher pressure than the boiling point of water at operating temperatures. While PWRs are stable and have separate coolant loops, they have higher costs and complexity than other reactor designs.
This presentation is intended for a class discussion on the aspects of nuclear reactors, their parts and functions , their safety and effects in terms of fallouts.
The boiling water reactor (BWR) is a type of light water nuclear reactor that is used to generate electrical power. In a BWR, the reactor core heats water, which boils and turns to steam to directly drive a turbine. The steam then goes to a condenser and is converted back to liquid water before returning to the reactor core. This differs from a pressurized water reactor where the heated water does not boil. BWRs have advantages like higher thermal efficiency due to eliminating a heat exchanger circuit and using a lower pressure vessel than PWRs. However, BWRs also have disadvantages such as potential radioactive contamination of turbine mechanisms and requiring more elaborate safety precautions.

Energy efficiency has been important since the latter part of the last century. The main object of this survey is to determine the energy efficiency knowledge among consumers. Two separate districts in Bangladesh are selected to conduct the survey on households and showrooms about the energy and seller also. The survey uses the data to find some regression equations from which it is easy to predict energy efficiency knowledge. The data is analyzed and calculated based on five important criteria. The initial target was to find some factors that help predict a person's energy efficiency knowledge. From the survey, it is found that the energy efficiency awareness among the people of our country is very low. Relationships between household energy use behaviors are estimated using a unique dataset of about 40 households and 20 showrooms in Bangladesh's Chapainawabganj and Bagerhat districts. Knowledge of energy consumption and energy efficiency technology options is found to be associated with household use of energy conservation practices. Household characteristics also influence household energy use behavior. Younger household cohorts are more likely to adopt energy-efficient technologies and energy conservation practices and place primary importance on energy saving for environmental reasons. Education also influences attitudes toward energy conservation in Bangladesh. Low-education households indicate they primarily save electricity for the environment while high-education households indicate they are motivated by environmental concerns.
DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODELijaia
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

data. Here all the communication is taken in secure manner. That is, in this
application the information will be stored in client itself. For further security the
data base is stored in the back-end oracle and so no intruders can access it.
4. Nuclear Reactor
A nuclear reactor produces and controls the release of
energy from splitting the atoms of certain elements. In a
nuclear power reactor, the energy released is used as heat
to make steam to generate electricity.
5. History
The world's first nuclear reactors operated naturally
in a uranium deposit about two billion years ago. These
were in rich uranium ore bodies and moderated by
percolating rainwater. The 17 known at Oklo in west
Africa, each less than 100 kW thermal, together
consumed about six tones of that uranium.
6. COMPONENTS OF NUCLEAR REACTOR
There are several components common to most types of
reactors:
Fuel. Uranium is the basic fuel. Usually pellets of
uranium oxide (UO2) are arranged in tubes to form fuel
rods. The rods are arranged into fuel assemblies in the
reactor core
Moderator. Material in the core which slows
down the neutrons released from fission so that they
cause more fission. It is usually water, but may be heavy
water or graphite.
Coolant.A fluid circulating through the core so
as to transfer the heat from it. In light water reactors the
7. water moderator functions also as primary coolant.
Except in BWRs, there is secondary coolant circuit where
the water becomes steam. (See also later section on
primary coolant characteristics)
Containment. The structure around the reactor
and associated steam generators which is designed to
protect it from outside intrusion and to protect those
outside from the effects of radiation in case of any serious
malfunction inside. It is typically a meter-thick concrete
and steel structure.
8. >Types Of Nuclear
Reactors
1 – PRESSURISED WATER REACTOR
This is the most common type, with over 230 in use
for power generation and several hundred more
employed for naval propulsion. The design of PWRs
originated as a submarine power plant. PWRs use
ordinary water as both coolant and moderator. The
design is distinguished by having a primary cooling
circuit which flows through the core of the reactor under
very high pressure, and a secondary circuit in which
steam is generated to drive the turbine. In Russia these
9. are known as VVER types – water-moderated and -
cooled.
A PWR has fuel assemblies of 200-300 rods each,
arranged vertically in the core, and a large reactor would
have about 150-250 fuel assemblies with 80-100 tones of
uranium.
Water in the reactor core reaches about 325°C, hence
it must be kept under about 150 times atmospheric
pressure to prevent it boiling. Pressure is maintained by
steam in a pressurizes (see diagram). In the primary
cooling circuit the water is also the moderator, and if any
of it turned to steam the fission reaction would slow
down. This negative feedback effect is one of the safety
features of the type. The secondary shutdown system
involves adding boron to the primary circuit.
10. The secondary circuit is under less pressure and the
water here boils in the heat exchangers which are thus
steam generators. The steam drives the turbine to
produce electricity, and is then condensed and returned
to the heat exchangers in contact with the primary circuit
2-Boiling water reactor
(BWR)
This design has many similarities to the PWR, except
that there is only a single circuit in which the water is at
lower pressure (about 75 times atmospheric pressure) so
that it boils in the core at about 285°C. The reactor is
designed to operate with 12-15% of the water in the top
11. part of the core as steam, and hence with less moderating
effect and thus efficiency there. BWR units can operate
in load-following mode more readily then PWRs.
The steam passes through drier plates (steam
separators) above the core and then directly to the
turbines, which are thus part of the reactor circuit. Since
the water around the core of a reactor is always
contaminated with traces of radionuclide's, it means that
the turbine must be shielded and radiological protection
provided during maintenance. The cost of this tends to
balance the savings due to the simpler design. Most of the
radioactivity in the water is very short-lived*, so the
turbine hall can be entered soon after the reactor is shut
down.

radioactivity in the water is very short-lived*, so the
turbine hall can be entered soon after the reactor is shut

A BWR fuel assembly comprises 90-100 fuel rods, and
there are up to 750 assemblies in a reactor core, holding
up to 140 tones of uranium. The secondary control
13. system involves restricting water flow through the core so
that more steam in the top part reduces moderation.
3-Pressurised heavy
water reactor (PHWR)
The PHWR reactor design has been developed since
the 1950s in Canada as the CANDU, and from 1980s also
in India. PHWRs generally use natural uranium (0.7% U-
235) oxide as fuel, hence needs a more efficient
moderator, in this case heavy water (D2O).** The PHWR
produces more energy per kilogram of mined uranium
than other designs, but also produces a much larger
amount of used fuel per unit output
14. The moderator is in a large tank called a calandria,
penetrated by several hundred horizontal pressure tubes
which form channels for the fuel, cooled by a flow of
heavy water under high pressure in the primary cooling
circuit, reaching 290°C. As in the PWR, the primary
coolant generates steam in a secondary circuit to drive
the turbines. The pressure tube design means that the
reactor can be refueled progressively without shutting
down, by isolating individual pressure tubes from the
cooling circuit. It is also less costly to build than designs
with a large pressure vessel, but the tubes have not
proved as durable.
A CANDU fuel assembly consists of a bundle of 37 half
meter long fuel rods (ceramic fuel pellets in zircaloy
tubes) plus a support structure, with 12 bundles lying end
15. to end in a fuel channel. Control rods penetrate the
calandria vertically, and a secondary shutdown system
involves adding gadolinium to the moderator. The heavy
water moderator circulating through the body of the
calandria vessel also yields some heat (though this circuit
is not shown on the diagram above).
Newer PHWR designs such as the Advanced Candu
Reactor (ACR) have light water cooling and slightly-
enriched fuel.
CANDU reactors can accept a variety of fuels. They
may be run on recycled uranium from reprocessing LWR
used fuel, or a blend of this and depleted uranium left
over from enrichment plants. About 4000 MWe of PWR
might then fuel 1000 MWe of CANDU capacity, with
16. addition of depleted uranium. Thorium may also be used
in fuel.
4-Advanced gas-cooled
reactor (AGR)
These are the second generation of British gas-cooled
reactors, using graphite moderator and carbon dioxide as
primary coolant. The fuel is uranium oxide pellets,
enriched to 2.5-3.5%, in stainless steel tubes. The carbon
dioxide circulates through the core, reaching 650°C and
then past steam generator tubes outside it, but still inside
the concrete and steel pressure vessel (hence 'integral'
design). Control rods penetrate the moderator and a
17. secondary shutdown system involves injecting nitrogen to
the coolant.
5-Light water graphite-
moderated reactor
(RBMK)
This is a Soviet design, developed from plutonium
production reactors. It employs long (7 meter) vertical
pressure tubes running through graphite moderator, and is
cooled by water, which is allowed to boil in the core at
290°C, much as in a BWR. Fuel is low-enriched uranium
oxide made up into fuel assemblies 3.5 meters long. With
moderation largely due to the fixed graphite, excess boiling
simply reduces the cooling and neutron absorption without
18. inhibiting the fission reaction and a positive feedback
problem can arise, which is why they have never been built
outside the Soviet Union.
6-Fast neutron
reactors (FNR)
Some reactors (only one in commercial service) do not
have a moderator and utilize fast neutrons, generating
power from plutonium while making more of it from the
U-238 isotope in or around the fuel. While they get more
than 60 times as much energy from the original uranium
compared with the normal reactors, they are expensive to
build. Further development of them is likely in the next
decade, and the main designs expected to be built in two
decades are FNRs. If they are configured to produce more
19. fissile material (plutonium) than they consume they are
called Fast Breeder Reactors (FBR).
