In 2001, the Bulgarian Government decided to refurbish and convert the research reactor in Sofia into a low-power reactor. Due to this, a partial dismantling of IRT-Sofia?s old systems and equipment was carried out with the intention of reusing the concrete bioshield in the construction of the new low-power research reactor. For a more efficient use of available resources, an engineering project known as ?The plan for the partial dismantling of IRT-Sofia equipment as a part of its refurbishment into a low-power research reactor? was drawn up and has since been successfully implemented.

After the decision of the Bulgarian Government to reconstruct it, the strategy concerning the IRT-Sofia Research Reactor is to partially dismantle the old systems and equipment. The removal of the reactor core and replacement of old equipment will not pose any significant problems. For a more efficient use of existing resources, there is a need for an engineering project which has been already prepared under the title "General Plan for the Partial Dismantling of Equipment at the IRT-Sofia as a Part of the Reconstruction into a Low Power RR".

In this work, control rod worth, xenon (Xe) effect on reactivity and power defect have been measured by doing experiments in the BAEC TRIGA Mark-II research reactor (BTRR) and through established theoretical analysis. Firstly, to study the xenon-135 effect on reactivity, reactor is critical at 2.4 MW for several hours. Next, experiments have been performed at very low power (50 W) to avoid temperature effects. Moreover, for the power defect experiment, different increasing power level has been tested by withdrawing the control rods. Finally, it is concluded that the total control rods worth of the BAEC TRIGA Mark-II research reactor, as determined through this study, is enough to run the reactor at full power (3 MW) considering the xenon-135 and fuel temperature effects.
