Abstract

Abstract

After the use of low-enrichment fuel in MJTR, the loading of the core has been changed. The core parameters are used to calculate the change rule of ¹³⁵Xe and ¹⁴⁹Sm, and the effect on the core reactivity. Then the curves of core reactivity in nominal operating condition and shut down condition are given, which makes the operator understand the change rule of toxic reactivity and response to the change of working condition in actual operation and ensure the safe operation of the reactor.
