+-- W = water node, # = reactor core, | = HV cable
+--
+-- The man-hole and the HV cable are only in the middle, and the man-hole
+-- is optional.
+--
+-- For the reactor to operate and not melt down, it insists on the inner
+-- 7x7x7 portion (from the core out to the blast-resistant concrete)
+-- being intact. Intactness only depends on the number of nodes of the
+-- right type in each layer. The water layer must have water in all but
+-- at most one node; the steel and blast-resistant concrete layers must
+-- have the right material in all but at most two nodes. The permitted
+-- gaps are meant for the cable and man-hole, but can actually be anywhere
+-- and contain anything. For the reactor to be useful, a cable must
+-- connect to the core, but it can go in any direction.
+--
+-- The outer concrete layer of the standard structure is not required
+-- for the reactor to operate. It is noted here because it used to
+-- be mandatory, and for historical reasons (that it predates the
+-- implementation of radiation) it needs to continue being adequate
+-- shielding of legacy reactors. If it ever ceases to be adequate
+-- shielding for new reactors, legacy ones should be grandfathered.
