The reactivity measurement in a subcritical assembly using the area ratio method is affected by the detector location and needs to be corrected for spatial dependence. One of the approaches to calculate the spatial correction factor is based on steady-state numerical simulation as proposed by Bell and Glasstone. This paper discusses the evaluation of the spatial correction factor for the BRAHMMA (BeO Reflected And HDPe Moderated Multiplying Assembly) subcritical assembly, India. The factors have been used to correct experimentally measured reactivity values from the area ratio method at different locations inside the core.
