Thorium fuel cycle

energy

The thorium fuel cycle is a nuclear fuel cycle that uses an isotope of thorium, 232Th, as the fertile material.

Three Gorges Dam

energy

The Three Gorges Dam is a hydroelectric gravity dam that spans the Yangtze River by the town of Sandouping, in Yiling District, Yichang, Hubei province, central China, it has been the world's largest power station in terms of installed capacity (22,500 MW) since 2012.

Three phase electric power

energy

Three-phase electric power is a common method of alternating current electric power generation, transmission, and distribution.

Threshold

marine

The value of input to a measuring instrument, or any system, below which no output change can be detected.

Threshold energy

energy

In particle physics, the threshold energy for production of a particle is the minimum kinetic energy a pair of traveling particles must have when they collide.

Threshold limit value

energy

The threshold limit value (TLV) of a chemical substance is believed to be a level to which a worker can be exposed day after day for a working lifetime without adverse effects.

Threshold limit value (TLV)

marine

The time-weighed average concentration of a substance to which workers may be repeatedly exposed, without adverse effect.

Throat of a fillet weld

marine

Actual throat, the shortest distance between the weld root and the face of a fillet weld.

Throttle

energy

A throttle is the mechanism by which fluid flow is managed by constriction or obstruction.

Thrust bearing

marine

A bearing located inside the ship to transmit the propeller thrust from the shafting to the hull structure.

Thrust block

marine

The complete assembly of thrust shaft and bearings which is solidly constructed and mounted onto a rigid seating.

Thrust power

marine

The product of the propeller thrust and speed of vessel advance.

Thrust shaft

marine

A short length of shaft with flanges at either end and a thrust collar in the centre.

Thruster system of dynamic positioning system

marine

All components and systems necessary to supply the DP system with thrust force and thruster direction.

Thrusters

marine

Thrusters are used to allow ships to be more independent from tugs, give them more manoeuvrability for special tasks, and in some cases give them a “take home” capability.

Thunderstorm

energy

A thunderstorm, also known as an electrical storm or a lightning storm, is a storm characterized by the presence of lightning[1] and its acoustic effect on the Earth's atmosphere, known as thunder.

Thyristor

energy

A solid-state semiconductor device with four layers of alternating P- and N-type materials.

Thyristor-controlled reactor

energy

Thyristor-controlled reactors can be used for limiting voltage rises on lightly loaded transmission lines.

Thyristor-switched capacitor

energy

A thyristor-switched capacitor is a type of equipment used for compensating reactive power in electrical power systems.

Tidal barrage

energy

A tidal barrage is a dam-like structure used to capture the energy from masses of water moving in and out of a bay or river due to tidal forces.
