Perhaps the most important measure that engineers have developed is the neutron absorption capacity (σ), which is measured in units of barns and is a function of microscopic cross section. Also, the amount of time that the reactor cannot override the effects of built up Xe-135 is called poison outage time. For instance, the time during which there is an inability to start a reactor due to the buildup of Xe-135 is referred to as the precluded start-up time. To help account for this, engineers have developed measurements to quantify the impact of Xe-135 on nuclear operations. Xe-135 is a well-known neutron poison, and thus can impact the continued chain reaction of a nuclear power plant if it becomes over abundant during power generation. U-235 absorbs a neutron, and subsequently generates neutrons (which power the chain reaction) and Xe-135. This natural by-product can stop the desirable chain reaction present in a nuclear reactor used for power generation.įor example, in nuclear power plants, U-235 is used as a fuel. These are used to help store nuclear waste and slow nuclear reactions, but are also generated naturally in nuclear chain reactions as a by-product. In the operation of nuclear reactors, engineers make use of substances known as neutron poisons.
