Nuclear Power plant project Report

 General Layout of Nuclear Power Plant-

The Main components of a NUCLEAR POWER PLANT are :-

Nuclear Reactor

Heat Exchanger ( Steam Generator )

Steam Turbine

Generator

Steam Condenser

Cooling Tower

Coolent Pump

Basic components of Nuclear power plant are :-

Nuclear Reactor :- It is the heart of the nuclear power plant. In nuclear reactor, nuclear fission of radioactive material takes place. This generates large amount of heat energy. This heat is taken by the coolent circulating through the reactor core. After absorbing the heat, the coolent becomes hot.

Heat Exchanger ( Steam Generator ) :- The hot coolent coming from nuclear reactor flows through tubes of heat exchanger. In heat exchanger, hot coolent gives up heat to feed water so that it can be converted into steam. After giving up heat, the coolent is again pumped back to nuclear reactor.

Steam Turbine :- Steam produced in heat exchanger is expanded in steam turbine to produce mechanical energy.

Generator :- Output shaft of steam turbine is coupled to generator. The generator converts mechanical energy into electrical energy i.e. electricity.

Condenser :- The exhaust steam leaving the steam turbine is passed through the condenser where it is cooled and condensed to water with the help of cooling water from cooling tower. This feed water is pumped back to heat exchanger with the help of feed water pump.

Nuclear Fuels :-

Natural Uranium U235

Uranium Isotope U238

Plutonium Pu239

Site Selection for NUCLEAR POWER PLANT :-

Availability of Water :- The plant should be nearer to sea, river or reservoir as it needs water for steam generation and condenser cooling.

Distance from Load Centre :- The plant should be located near the load centre to reduce power transmission losses.

Distance from Populated Area :- the plant should be located away from populated area to safeguard the people from hazardous radioactive radiations.

Waste Disposal :- The wastes of nuclear power plant are radioactive and hence there should be sufficient space near the plant site for waste disposal.

Safeguard against Earthquakes :- The site should be away from seismic zone.

Availability of Transport Facility :- The site selected should have rail and road transport facilities.

ADVANTAGES OF NUCLEAR POWER PLANT :-

It requires less space as compared to other conventional power plants of same capacity.

It requires small amount of fuel hence there are no problem of fuel transportation and storage.

It is not affected by adverse weather conditions.

It is more reliable in operation.

It is well suited to meet large power demands.

These plants are non-polluting.

DISADVANTAGES OF NUCLEAR POWER PLANT :-

Its capital cost is high.

It needs trained manpower.

Its maintenance cost is high.

The cost of power generation is high.

Nuclear waste disposal is a big problem.

High degree of safety is needed for the persons working on these plants against nuclear radiations.

Types of joint (knuckle joint ,cotter joints and turnbuckle joint)

INTRODUCTION OF KNUCKLE JOINT: . A knuckle joint is a mechanical joint used to connect two rods which are under a tensile load, when there is a requirement of small amount of flexibility, or angular moment is necessary. There is always axial or linear line of action of load.  The knuckle joint assembly consists of the following major components: Single eye. Double eye or fork Knuckle pin. Collar Taper pin At one end of the rod the a single eye is formed and a double eye is formed at the other end of the rod. Both, single and double eye are connected by a pin inserted through the eye. The pin has a head at one end and at other end there is a taper pin or split pin. For gripping purpose, the ends of the rod are of octagonal forms. Now, when the two eyes are pulled apart, the pin holds them together. The solid rod portion of the joint in this case is much stronger than the portion through which the pin passes.  The modes of failure are: Shear failure of pin (single shear). Crushi...

STUDY OF DRUM BRAKE

What is drum brake? A drum brake is a brake that uses friction caused by a set of shoes or pads that press outward against a rotating cylinder-shaped part called a brake drum. The term drum brake usually means a brake in which shoes press on the inner surface of the drum. When shoes press on the outside of the drum, it is usually called a clasp brake. Where the drum is pinched between two shoes, similar to a conventional disc brake, it is sometimes called a pinch drum brake, though such brakes are relatively rare. A related type called a band brake uses a flexible belt or "band" wrapping around the outside of a drum. Components:- 1. Backing plate 2. Brake drum 3. Wheel cylinder 4. Brake shoes. Backing plate The backing plate provides a base for the other components. The back plate also increases the rigidity of whole set-up, supports the housing, and protects it from foreign materials like dust and other road debris. It absorbs the torque from the braking action, and that is ...

Automation and it's Types ( programmable, Fixed and flexible Automation)

Automation and it's Types Automation is the creation of technology and its application in order to control and monitor the production and delivery of various goods and services. It performs tasks that were previously performed by humans. Automation is being used in a number of areas such as manufacturing, transport, utilities, defense, facilities, operations and lately, information technology.
