Characteristics of Fissile Solution Systems
Abstract
This report describes some of the characteristics of fissile solutions systems, namely: the ability of fuel to flow rapidly during operation due to thermal forces and radiolytic gas dynamics drives the physics of these systems; exhibition of high negative reactivity feedback due to fuel temperature increase and radiolytic gas generated void (both decrease fuel density); evidence of well-damped systems and bounded reactivity excursions result in bounded (new) steady-state operating condition; they are very docile and slow to respond due to long neutron lifetime and high thermal inertia of the fuel (specific heat of fuel is an order of magnitude greater than solid fuels); operation requires large excess reactivity to be available ($5.00 or more); and finally they are sensitive to auxiliary systems such as cooling water, gas handling, and water makeup; small changes can have large effects due to the large feedbacks
