A Pressurized Water Reactor (PWR) is a type of nuclear reactor where water is used as both a coolant and a moderator, maintained under high pressure to prevent it from boiling. This design is the most common type of nuclear reactor in the world due to its inherent safety features and efficiency in generating electricity.

Pressurized Water Reactor

A nuclear reactor is a device used to initiate and control a sustained nuclear chain reaction, primarily for generating electricity or for research purposes. It operates on the principle of nuclear fission, where the nucleus of an atom splits into smaller parts, releasing a significant amount of energy in the form of heat, which is then used to produce steam that drives turbines for electricity generation.

A coolant is a substance used to reduce or regulate the temperature of a system by absorbing and dissipating heat. It is crucial in maintaining optimal operating temperatures in engines, industrial processes, and electronic devices, preventing overheating and ensuring efficiency and safety.

Coolant

A moderator is an individual or tool that facilitates discussion, ensures adherence to guidelines, and maintains a balanced environment in various settings, such as online forums, academic discussions, or focus groups. Moderators play a crucial role in conflict resolution, content curation, and the promotion of inclusive and productive interactions.

High Pressure

Boiling is the process where a liquid turns into vapor when its vapor pressure equals the atmospheric pressure, occurring at a specific temperature known as the boiling point. This phase transition involves energy absorption, which is used to break intermolecular bonds rather than increase temperature, resulting in a constant temperature until all the liquid has vaporized.

Inherent safety features

Efficiency is the ability to achieve a desired outcome with the least amount of wasted resources, such as time, energy, or materials. It is a critical factor in both economic systems and engineering processes, driving innovation and competitiveness by maximizing output while minimizing input.
