The video below serves an excellent illustration of Brayton cycle:

The essential requirement for power plants to be operated as peak load plants is

The essential requirement for power plants to be operated as peak load plants is

1. Capability of quick starts
2. Low capital cost
3. Quick response to load variation
4. All of these

Correct answer: 4. All of these

The efficiency of steam power plant efficiency can be improved by

The efficiency of steam power plant efficiency can be improved by

1. Burning large amount of coal
2. Decreasing the load on the plant
3. Using high temperature and high pressure steam
4. Using large quantity of water

Correct answer: 3. Using high temperature and high pressure steam

The conversion ratio of breeder reactor are

The conversion ratio of breeder reactor are

1. 1
2. Less than 1
3. Greater than 1
4. None of above

Correct answer: 3. Greater than 1

Explanation: Breeder reactors are type of nuclear reactors that generates more fissile material than it consumes. Fast breeder reactors can convert more fertile material to fissile material and therefore net fuel consumption is much less. As a result the conversion ratio is greater than 1.
