machine for controlled nuclear reactions
A large machine where nuclear reactions are controlled to make heat or power, often used in power stations.
Модел на употреба:
a/an [adjective] reactor
Честа грешка:
Learners sometimes confuse "reactor" with "reactor plant" or "power plant". A reactor is the machine where the nuclear reaction happens, while the power plant is the whole facility, including the reactor, cooling systems, buildings, and other equipment.
Синоними
nuclear reactor (More explicit; specifically names that the reactor uses nuclear energy.)
Антоними
solar panel (Uses sunlight to produce power instead of nuclear reactions; not a direct opposite but a contrasting type of power source.)

vessel for controlled chemical reactions
A closed container or system where chemicals are mixed and controlled so they react in a planned way, especially in factories or labs.
Модел на употреба:
a/an [adjective] reactor
Честа грешка:
Learners may confuse "reactor" with "reactant". A "reactor" is the container or system, while a "reactant" is a substance that takes part in a chemical reaction.
Синоними
reaction vessel (Common technical term; stresses the container aspect more than the engineered system as a whole.)
Антоними
storage tank (Holds chemicals without promoting reaction, whereas a reactor is designed for reactions to occur.)

Примери
- The mixture was pumped into the reactor and heated to 200°C.
- A fault in the reactor caused the reaction to run out of control.
- They scaled up the laboratory process to a pilot-scale reactor.
- Stirring speed inside the reactor can affect the product quality.
Примери за учащи
- The chemicals react inside the reactor.
- The factory uses a big reactor to make the product.
- We keep the reactor at a high temperature.
- The engineer cleaned the reactor before starting the process.

person who records reactions to content
A person who makes and shares videos showing how they react to other videos, music, or games.
Модел на употреба:
a/an [adjective] reactor
Честа грешка:
Learners sometimes think "reactor" in this sense means any person who simply reacts in real life. In everyday conversation, people usually say someone "reacts" or is a "reviewer" or "commentator"; "reactor" for a person is mainly used for online creators who make reaction videos.
Синоними
content creator (Broader; includes many types of creators, not only those who focus on reaction videos.)
Антоними
bystander (A person who only watches and does not actively comment, react publicly, or create content.)
