Pinch fusion reactor
 An assault carrier's pinch fusion reactor Pinch fusion reactors are nuclear fusion reactors that served as a source of power generation used by the Covenant.[1] Using deuterium and tritium as fuel,[2] pinch fusion reactors replicate the conditions inside the core of a star to generate enormous amounts of plasma and power. These reactors power the weapons and engines of warships,[1] the impulse drives of smaller ships,[3] and even the combat harnesses of Sangheili warriors.[4] The pinch fusion reactor serves as the primary source of power for Covenant warships, though a handful of classes were powered by shrine-cores, power plants extracted from Forerunner machinery.[5] Description[edit]The reactors use focused artificial gravity generators to initiate and sustain a fusion reaction, replicating the conditions inside the core of stars. This process generates an enormous amount of power and plasma.[1][6] Through deuterium-tritium fusion, the plasma that is generated is compressed and heated by pinched magnetic fields.[2] Non-essential ship systems may be rendered inert or disconnected to divert the output of the reactors entirely to specific systems, such as armaments or propulsion.[7] The reactors are surprisingly primitive for the Covenant,[2] and are quite volatile.[6] If their cooling systems become disabled or their maximum heat loads are exceeded, they can often fail explosively[8]—the reactors can detonate with the power of a small supernova should containment efforts fail.[1] They provide 12 terawatts per reactor.[9] Applications and usage[edit]Pinch fusion reactors are most notably used on Covenant warships, powering the weapons and engines. The CPV-class heavy destroyer has two pinch fusion reactors; the primary reactor powers the destroyer's powerful superheavy excavation beam, while the secondary reactors power the rest of the ship.[1] The largest pinch fusion reactor of the CCS-class battlecruiser provides the energy needed to ignite plasma torpedoes and charge its excavation beam.[10] The impulse drives fitted on fighters, dropships, and shuttles are powered by a small pinch fusion reactor.[3] Scaled-down reactors are used to power the Covenant's Type-38 "Tyrant" anti-air cannons and Sangheili combat harnesses, with a modified version being incorporated into the Sangheili-designed HELIOSKRILL-class Mjolnir.[4] Unyielding Hierophant was also powered by pinch fusion reactors.[8] In order to obtain fuel for their pinch fusion reactors, the Covenant operate various groundside facilities on worlds rich in tritium and deuterium, including hydro-processing centers[11] and massive refineries such as that on Pegasi Delta.[12] Gallery[edit]
