Implementation of the partial dismantling of research reactor IRT-Sofia prior to its refurbishment

Abstract

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.
