I could be mistaken but wasn’t the issue that when the rods were fully withdrawn the graphite was also partially withdrawn so when they scrammed the first thing that happened was an insertion of positive reactivity from the graphite which was enough positive reactivity to burn up all the xenon which then caused the reactor to go prompt critical?
Like the presence of the graphite wasn’t that bad but it combined with a lack of interlocks and improperly trained operators was the big problem and of course trying to start up at the peak of a xenon transient is never ideal
