Application of the ALARA Principle in Dismantling and Disposal of a Research Reactor Primary Cooling System Delay Tank

This work discusses the decommissioning plan of GRR-1 reactor old delay tank. The tank inner surface area presents low contamination. In this work the processes and methods that will be used to decontaminate, cut, dismantle, remove and release of the delay tank materials in a safe and organized manner in order to prevent undue radiation exposures to the facility staff, public and the environment according to the ALARA principle are discussed
