The enterprise conducts operations connected with handling of spent nuclear fuel and RW accumulated from naval activities and formed at decommissioning of nuclear submarines and nuclear-powered surface ships as well as operations on environmental rehabilitation of radiation-hazardous sites.

Within the framework of decommissioning NPS and nuclear maintenance ships RosRAO solves a number of complicated matters:

• Safe storage of reactors of decommissioned nuclear-powered submarines (NPS) and nuclear maintenance ships removed from naval forces.
• Rehabilitation of contaminated sites and premises of branches of the enterprise.
• Construction of complexes (buildings and structures) meant for implementing nuclear and radiation works for managing spent fuel and RW.
• Preparation of production for forming single-unit reactor from multiple-unit blocks at long storage repository site.
• Expansion of plant facilities for securing formation of reactor compartments, utilization of NPS and nuclear maintenance ships.
• Maintenance of buildings, sites and facilities by managing spent fuel and RW.
• Storage of spent fuel and RW in coastal repositories of the enterprise.
• Maintenance of facility infrastructure, providing it with utilities, transport and communication.
• Providing nuclear and radiation safety by managing spent fuel and RW.
