2022 Polaris RZR Pro R Ultimate 4-Seater. The Polaris RZR (Often pronounced as POLARIS RAZOR), is a sport side-by-side produced by Polaris Industries. When launched in 2007 as a 2008 model, it was officially known as the Ranger RZR, as it was marketed as a sub-model of the larger, work-oriented Ranger. As the RZR gained popularity, Polaris ...
Another advantage of liquid sodium coolant is that sodium melts at 371K (98°C) and boils / vaporizes at 1156K (883°C), a difference of 785K (785°C) between solid / frozen and gas / vapor states. By comparison, the liquid temperature range of water (between ice and gas) is just 100K at normal, sea-level atmospheric pressure conditions.
The normal coolant flow is 8000 m 3 /h per pump; this is throttled down by control valves to 6,000–7,000 m 3 /h when the reactor power is below 500 MWt. Each pump has a flow control valve and a backflow preventing check valve on the outlet, and shutoff valves on both inlet and outlet.

The Three Mile Island accident was a partial nuclear meltdown of the Unit 2 reactor (TMI-2) of the Three Mile Island Nuclear Generating Station on the Susquehanna River in Londonderry Township, near Harrisburg, Pennsylvania. The reactor accident began at 4:00 a.m. on March 28, 1979, and released radioactive gases and radioactive iodine into the ...
A coolant is a substance, typically liquid, that is used to reduce or regulate the temperature of a system. An ideal coolant has high thermal capacity, low viscosity, is low-cost, non-toxic, chemically inert and neither causes nor promotes corrosion of the cooling system. Some applications also require the coolant to be an electrical insulator .
A pressurized water reactor ( PWR) is a type of light-water nuclear reactor. PWRs constitute the large majority of the world's nuclear power plants (with notable exceptions being the UK, Japan and Canada). In a PWR, the primary coolant ( water) is pumped under high pressure to the reactor core where it is heated by the energy released by the ...
