The Chernobyl Disaster

Nuclear engineers can explain to you that this kind of shut-down would result in an unusually large amount of Xenon build-up in the reactor fuel. Xenon eats up neutrons, thus making the chain reaction more difficult to maintain. Because of this, the operators were surprised when the reactor went to a lower power than they had expected.

Xenon-135 Reactor Poisoning

The reactor eventually shuts down due to xenon accumulation. Understanding how to deal with the produced Xe-135 is essential to keep the reaction chain sustainable and the neutron flux at desired rate. When operating a new reactor, the startup stage initially has no trace xenon, and the reactor is maintained critical at a low power level.

Xenon 135 - Nuclear Power

Production and Removal of Xenon 135. In general, there are two ways of xenon 135 production in the reactor:. Decay of 135 I.Most of xenon 135 is produced by beta decay of 135 I (γ I,total = 6.4%). In fact, the 135 I is a direct fission product (γ I = 3.1%) and a decay product of tellurium 135 (γ Te = 3.3%), but the half-life of tellurium 135 is so short (~ 19 sec), that iodine-135 can be .
