pyrophoricity; pyrophoricity

Property of certain materials to ignite spontaneously or with minimal energy input at room temperature.

inflammability; flammability

Property of certain materials to ignite with a greater or lesser input of energy.

Pressurized Water Reactor (PWR); Réacteur à Eau Pressurisée (REP)

A type of reactor in which the heat transfer fluid used to extract thermal energy from the nuclear fuel (primary circuit) is water, pressurized to around 150 bar so that it remains in liquid form. The steam produced in a secondary circuit via steam generators is then used to generate electricity via a turbine.

Réacteur à Eau Bouillante(REB); Boiling Water Reactor (BWR)
