machine for controlled nuclear reactions
A large machine where nuclear reactions are controlled to make heat or power, often used in power stations.
نمط الاستخدام:
a/an [adjective] reactor
خطأ شائع:
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.
المرادفات
nuclear reactor (More explicit; specifically names that the reactor uses nuclear energy.)
الأضداد
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.
نمط الاستخدام:
a/an [adjective] reactor
خطأ شائع:
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.
المرادفات
reaction vessel (Common technical term; stresses the container aspect more than the engineered system as a whole.)
الأضداد
storage tank (Holds chemicals without promoting reaction, whereas a reactor is designed for reactions to occur.)

أمثلة
- 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.
أمثلة للمتعلّمين
- The chemicals react inside the reactor.
- The factory uses a big reactor to make the product.
- We keep the reactor at a high temperature.

person who records reactions to content
A person who makes and shares videos showing how they react to other videos, music, or games.
نمط الاستخدام:
a/an [adjective] reactor
خطأ شائع:
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.
المرادفات
content creator (Broader; includes many types of creators, not only those who focus on reaction videos.)
الأضداد
bystander (A person who only watches and does not actively comment, react publicly, or create content.)
