Pressurized Water Reactor:
A Pressurized Water Reactor (PWR) in a power station has a negative temperature coefficient. After it has been operating for a long time at a partial load, explain, using the diagram in Figure Q3, how the operators achieve the increase of power and the events inside the reactor and associated systems which occur in consequence.
Using suitable case studies,
a) Describe the processes and components utilised in a typical natural gas fired combined cycle gas turbine (CCGT) power station,
b) Explain why a CCGT power plant is superior in efficiency to a regular PF coal power plant. Do not submit web based drawings but present your own simple schematic representation(s) of a CCGT installation.
