Iodine-135 is an isotope of iodine with a half-life of 6.6 hours. It is an important isotope from the viewpoint of nuclear reactor physics . It is produced in relatively large amounts as a fission product , and decays to xenon-135 , which is a nuclear poison with the largest known thermal neutron cross section , which is a cause of multiple ...

The iodine pit, also called the iodine hole or xenon pit, is a temporary disabling of a nuclear reactor due to buildup of short-lived nuclear poisons in the reactor core. The main isotope responsible is 135 Xe, mainly produced by natural decay of 135 I. 135 I is a weak neutron absorber, while 135 Xe is the strongest

Neutron capture (29 barns) slowly converts stable 133 Cs to 134 Cs, which itself is low-yield because beta decay stops at 134 Xe; can be further converted (140 barns) to 135 Cs. 6.3333%: Iodine, xenon: 135 I → 135 Xe: 6.57 h: Most important neutron poison; neutron capture converts 10–50% of 135 Xe to 136 Xe; remainder decays (9.14h) to 135 ...

Because 95% of the xenon-135 production is from iodine-135 decay, which has a 6- to 7-hour half-life, the production of xenon-135 remains constant; at this point, the xenon-135 concentration reaches a minimum. The concentration then increases to the equilibrium for the new power level in the same time, roughly 40 to 50 hours.
