I have implemented this; you can try the new quantities (in group Boundary): maximum inscribed disc radius, centre x and y, in version 2.29.20120820 or later. A heuristic approach is used so it is not guaranteed that the absolutely largest inscribed disc is always found but the one found should be pretty close. To visualise the result you might also want to try Grains → Select Inscribed Discs, which apparently does nothing but it creates circular selections for each inscribed disc, and then go to Selection Manager tool to see them. The less common term insrcibed disc (as opposed to inscribed circle) was chosen to emphasise that the entire full disc must lie within the grain, not just its boundary (the circle). Which matters if the grain contains holes – you can use Fill Voids in Mask Editor tool if the marking procedure produces grains with holes but you do not want them.
