[[File:RELAP Desktop View.jpg|right|thumb|500px|[[Screenshot|Screen capture]] of a [[Three-dimensional space|three-dimensionally]] rotatable '''RELAP5-3D''' model of the [[Westinghouse Electric Company|Westinghouse]] [[Zion Nuclear Power Station]] showing the [[Porosity|void fraction]] (mixture of liquid and gaseous water by volume) as a number between 0 and 1. Violet portions represent 100% [[water]], while red portions indicate 100% [[steam]]. Other shades indicate the composition of the two-phase [[mixture]]. Users can [[Video overlay|overlay]] text on the image and add auxiliary [[GUI widget|widgets]] (such as plots and updating tables) to the [[Desktop environment|desktop]].]]RELAP5-3D has [[multidimensional]] [[thermal-hydraulic hydraulics]] and [[neutron]] kinetic modeling capabilities. The multidimensional component in RELAP5-3D was developed to allow the user to accurately model the multidimensional [[Fluid dynamics|flow]] behavior that can be exhibited in any component or region of a nuclear reactor coolant system. There is also two dimensional [[conductive]] and radiative [[heat transfer]] capability and modeling of plant trips and control systems.<ref>{{cite web|url=http://www.inl.gov/relap5/relap5doc/relap5doe.pdf |title=Relap5-3D |publisher=Inl.gov |accessdate=2012-11-26}}</ref> RELAP5-3D allows for the simulation of the full range of reactor transients and postulated accidents, including:

* [[Scram|Trips]] and [[Nuclear reactor#Reactivity control|controls]]

* Component models ([[Pressurized water reactor#Pumps|pumps]], valves, [[Steam separator|separators]], branches, etc.)
