Safety Analysis for Xi’an Pulsed Reactor in Pulse Operation Mode with the Core in Steady Arrangement and Design Project for the New Core Arrangement

Through the theoretical calculation of the safety parameters of Xi’an Pulsed Reactor,this paper analyzes the feasibility when the steady arrangement core runs in pulse mode.Based on the original design of steady arrangement core,the paper also gives two kinds of new core arrangements of Xi’an Pulsed Reactor.It calculates the physics parameters,safety parameters and the parameters of experimentation channels of this two kind of design projects.This work may be a reference for the simplification of the refueling program,improving the parameters of the certain channel and reducing the probability of failed fuel rod clad-ding.
