Abstract
Selfheating condition and following ignition in an Inertial Confinement Fusion ICF fuel pellet is evaluated by calculating the power equations dynamically In fact the selfheating condition is a criterion that determines the minimum parameters of a fuel such as temperature density and areal density that can be ignited Deuterium is the main component of ICF fuels as large amounts of it are naturally available In addition the use of deuterium as a fuel in ICF causes the production of tritium and helium3 However pure deuterium has a high ignition temperature hbox Tge 40hbox keV which makes it inefficient In this paper the power equations are solved dynamically and it has been indicated that internal tritium and helium3 production at early evolution of compressed deuterium fuel causes ignition at lower predicted temperatures
