Poisoning
 scroll 
Some of the fission products generated during the operation of a reactor
have a large capture cross-section for neutrons (e.g. Xe-135). The control
device must be adjusted to compensate for the reactivity equivalent
of the reactor poisons to keep the reactor at its power level. Reactor
poisons (e.g. boron acid solution) are injected into water-moderated
reactors for emergency shutdown. Boric acid solution is used to compensate
for excess reactivity in pressurized water reactors.
