The Radioactive Waste Management Centre (RWMC) was established by Ghana Atomic Energy Commission (GAEC) on behalf of the Government of Ghana to carry out the safe and secure management of radioactive waste generated in Ghana to protect human and the environment from the hazards associated with ionizing radiation. GAEC with assistance from the United States Department of Energy’s National Nuclear Security Administration (NNSA) Office of Global Threat Reduction Initiative (GTRI) has constructed a Centralized Radioactive Waste Management facility consisting of both storage and processing units to strengthen effective management of radioactive wastes in Ghana. The Centre operates the only radioactive waste storage facility in Ghana and the radioactive waste management practice entails safe storage pending the development of a suitable disposal facility.
The Centre is currently managed with a team comprising two (2) Senior Research Scientists, two (2) Research Scientist, four (4) Assistant Research Scientists, a Principal Technologist and a Senior Technologist.
Activities of the Centre include:
- Formulating policies and strategies for the safe and secured management of radioactive waste generated in Ghana;
- Collecting and transporting radioactive waste materials from users or generators;
- Safe and secure storage (transient and temporary) of radioactive waste materials at the Centralized Waste Processing and Storage facility;
- Executing predisposal activities such as pre-treatment, treatment and conditioning of disused sealed radioactive materials;
- Regular monitoring of radiation levels in and around the Centralized Waste Processing and Storage facility for prompt detection of safety aberrations;
- Undertaking on-site and off-site monitoring and measurement of ambient airborne radioactivity;
- Carrying out technical services and R&D in providing feasible solutions for radioactive waste management, especially, in the final disposal of these substances.
- Management and updating of national inventory of radioactive waste generated in Ghana.
Borehole Disposal System (BDS); Current status -Active
The Centre is currently conducting research activities in support of the implementation of the borehole disposal system developed under the IAEA/AFRA regional project. This project involves the disposal of Disused Sealed Radioactive Sources (DSRS) in a narrow diameter engineered borehole facility as a safe, secure and cost-effective disposal option for all conditioned DSRSs in storage.
