Week 12 - Thermal Power Engineering

What process in nuclear power plants creates heat?

• • Burning coal

• • Splitting atoms

• • Spinning turbines

• • Cooling water

What does the steam generator do in a nuclear power plant?

• • Splits uranium

• • Stores waste

• • Turns water into steam

• • Absorbs neutrons

What material is used in control rods to slow the reaction?

• • Boron

• • Water

• • Uranium

• • Steel

What is a major environmental benefit of nuclear power?

• • No CO₂ emissions

• • Uses less water

• • Creates no waste

• • Burns coal cleanly

What stops radiation from escaping in modern nuclear plants?

• • Turbine

• • Fuel rods

• • Coolant pipes

• • Containment building

Match the part of a nuclear power plant to its job

• • Where fission happens

• 1. Steam Generator

• • Turns steam into electricity

• 1. Reactor Core

• • Makes steam from water

• 1. Turbine

• Match the term to its definition

• 1. Fission

• 1. Coolant

• • Liquid or gas that removes heat

• • Dangerous leftovers from reactions

• 1. Radioactive Waste

• • Splitting atoms to release heat

Match the reactor type to its feature

• 1. Pressurized Water Reactor (PWR)

• • Uses gas like helium as coolant

• 1. VVER Reactor

• • Russian design with safety layers

• 1. Gas-Cooled Reactor

• • Keeps water liquid under pressure

• 1. Boiling Water Reactor (BWR)

• • Boils water directly in the core

Match the safety feature to its purpose

• • Adds water if core overheats

• 1. Radiation Sensors

• • Slows or stops the nuclear reaction

• 1. Emergency Cooling System

• • Detects leaks or high heat

• 1. Control Rods

• • Stops radiation from spreading

• 1. Containment Building

Match the environmental issue to its solution

• • Strong containment buildings

• • Safe storage underground

• • Careful water cooling

• 1. Thermal Pollution

• • Recycling plant water

• 1. Water Use

• 1. Radioactive Waste

• 1. Radiation Leaks
