Used THOMAS SWAN 19x2 GAN #9394132 for sale

THOMAS SWAN 19x2 GAN is a type of nuclear power reactor designed by General Atomics Corporation for naval use. Developed in the early 1950s, 19x2 GAN focuses on the moderation of the neutrons to reduce neutron leakage. This reactor uses thorium, an abundant metal in the earth's crust, for its fuel. The neutrons generated in the nuclear reactions are slowed down by the reflectors that surround the core and by the presence of the high-boron absorber plates located within the core. This feature contributes to the reactor's ability to maintain a stable, controlled power level. THOMAS SWAN 19x2 GAN features two primary reactor coolant systems, each of which circulates its own coolant around the core. The primary coolant is a low-enriched uranium alloy with a molybdenum-chromium discontinuous outer envelope. This outer envelope acts as a barrier to contain the heat from the core and direct it to the secondary cooling system. The secondary coolant system is either water or steam depending on the version of the reactor and the intended use. It is used to generate electricity or other useful forms of energy, as required. The internal structure of 19x2 GAN is composed of twelve fuel elements which are arrayed in three circles. Each fuel element consists of four homogeneous rods of thorium-uranium sub-assemblies which are housed inside a uranium-molybdenum fuel channel. This fuel channel is then housed within an aluminum cylinder called the core shroud. The core shroud helps structurally support the fuel channel and keeps the fuel elements separated so that they do not interfere with each other. Additionally, THOMAS SWAN 19x2 GAN employs a number of safety measures such as a scram switch which triggers if certain conditions, such as power level excursions, are detected. The scram switch shuts down the reactor within milliseconds and prevents it from reaching criticality. 19x2 GAN is also equipped with an emergency core cooling system, which feeds liquid into the reactor if necessary, to prevent it from reaching destructive temperatures. Due to its flexibility and affordability, THOMAS SWAN 19x2 GAN is a popular choice for naval vessels. It is capable of providing start-up and run away power for up to 10 years and is well suited for use in submarines and other ships. Furthermore, its simple design and effective safety systems make 19x2 GAN a reliable source of energy with wide ranging applications.
