REACTOR TEMPERATURE TRANSIENTS WITH SPATIAL VARIABLES PART I:RADIAL ANALYSIS

摘要

In nuclear reactors the temperature transients are normally treated, by using the well known "lumped model". This model does not take into account any effect due to the heat propagation inside the fuel element and the heat transport along the channel.nPurpose of this paper is therefore a critical analysis of the colutions of the heat balance equations with spatial variables.
