Nuclear reactor - Wikipedia

Nuclear reactor - Wikipedia

A nuclear reactor, formerly known as an atomic pile, is a device used to initiate and control a fission nuclear chain reaction or nuclear fusion reactions. Nuclear reactors are used at nuclear power plants for electricity generation and in nuclear marine propulsion.Heat from nuclear fission is passed to a working fluid (water or gas), which in turn runs through steam turbines.

Fukushima operators send robot into worst-hit melted reactor

Fukushima operators send robot into worst-hit melted reactor

A remote-controlled robot on Tuesday was used to probe the hardest-hit nuclear reactor at Japan's wrecked Fukushima plant, as officials push forward with clean-up operations that have been mired in delays and controversy. An earthquake and tsunami in 2011 unleashed a disastrous meltdown at Fukushima Daiichi's three reactors that partly…

What Is a Packed Bed Reactor? | COMSOL Blog

Aug 15, 2014 When designing a packed bed reactor, the design must include mass transfer (or species transport) in the bed as well as heat transfer and chemical reactions. Understanding and optimizing the heat transfer through packed beds is important in order to decrease the cost of running the equipment.

MABR Wastewater Treatment Products | Fluence

Easy-to-install MABR modules are energy-efficient and cost-effective, and ensure high effluent quality due to simultaneous nutrients revmoal. The SUBRE modules are suitable for installation in basin depths ranging from 1.5 m to 6 m (5-20 feet). The modules are anchored to the basin floor and are aerated by a separate low-pressure low-flow blower.

Fixed Bed Reactor - an overview | ScienceDirect Topics

High cost. • Multiple reactors in parallel are required for larger plants. • To avoid high pressure drop in the reactor tubes, large catalyst particles are needed resulting in low effectiveness factor (low catalyst activity per unit mass, resulting from difficulty of reactants to diffuse into the core of a catalyst particle). •
