Definition

Noun: A ship whose propulsion is provided by the energy generated by a nuclear reactor. This type of vessel uses a controlled nuclear fission reaction to produce heat, which is then typically used to create steam to drive turbines or engines.

Usage

This term is used specifically to describe a class of seafaring vessels distinguished by their power source. It is a technical and descriptive compound noun. - The primary characteristic of a nuclear-powered ship is its virtually unlimited operational range without the need for frequent refueling. - The term is most commonly applied to military vessels like aircraft carriers and submarines, but also to some icebreakers and, historically, to civilian cargo ships.

Examples

• The aircraft carrier is a formidable nuclear-powered ship capable of remaining at sea for over 20 years without refueling.
• The development of the first nuclear-powered ship, the USS Nautilus submarine, revolutionized naval warfare.
• Environmental groups have expressed concerns about the safety of decommissioning old nuclear-powered ships.

Advanced Usage

• The term can be used attributively (like an adjective) before another noun (e.g., nuclear-powered ship technology, nuclear-powered ship fleet).
• In strategic discussions, a nuclear-powered ship is often contrasted with conventionally powered (diesel or gas turbine) ships, emphasizing its endurance and logistical advantages.

Variants and Related Words

• Nuclear-powered submarine: A submarine that uses nuclear power for propulsion.
• Nuclear-powered aircraft carrier: A large warship that serves as a seagoing airbase and is powered by nuclear reactors.
• Nuclear propulsion: The general method of propelling a vehicle using nuclear energy.
• Reactor vessel: The core component of the nuclear power plant on such a ship.

Synonyms

• Atom-powered ship (less common, largely historical)
• Reactor-powered vessel (technical)

Related Phrases

• Nuclear marine propulsion: The field of engineering concerned with nuclear propulsion for ships.
• Refueling cycle: The long interval between required refueling operations for a nuclear reactor, a key feature of these ships.
