Abstract
The Ghana Research Reactor-1 (GHARR-1) Facility is a Miniature Neutron Source Reactor with a rated power of 30 kW. GHARR-1 was installed and attained criticality on December 17, 1994 and commissioned on 8 th March, 1995. It has since been in operation. The routine practices and operational procedures have been set out with clear emphasis on ageing management programme at the facility. Some electronic components are changed regularly during maintenance sessions and keeping to regular purification of the reactor and pool water to mitigate against corrosion. This paper outlines the ageing management programme and mitigation practices, strategies for ageing management; periodic safety reviews, consideration of ageing during design, design features for components and unit replacement, top beryllium shim addition, and succession planning. Information sharing with other operating organizations is one of the means considered by GHARR-1 to attain excellence
