A 1MW plant would have the neutron power of 2kW @ .2% neutron power, even @ .02% its still 200W of neutrons. A *lot* more than “radiation output of a classroom of kindergarteners”. E. Lerner has said this even in his first Google talk. There is a cool down time of hours/days after switch off before you can get your hands inside.
Rare side reactions matter.
