Decommissioning Cost Estimate for the Ghana Research Reactor‐1 Facility Using the CERREX‐D2 Software

open access: yesScience and Technology of Nuclear Installations, Volume 2026, Issue 1, 2026.
The Ghana Research Reactor‐1 facility would certainly be decommissioned, either at the end of its life or by a decision to discontinue its operation. In planning for GHARR‐1’s eventual decommissioning, estimating the overall decommissioning cost is a major activity that needs to be undertaken to support budgeting and decision‐making for the project. To
