From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Safety improvements could lower positive reactivity feedback such as reactivity voidcoefficient. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. This negative voidcoefficient is an important safety feature of these reactors. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The reactor's voidcoefficient depends on the core content; it ranges from negative with all the initial absorbers to positive when they are all removed. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Modern reactors are designed to prevent and withstand loss of coolant, regardless of their voidcoefficient, using various techniques. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. This capability is known as a negative voidcoefficient of reactivity. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The total water loss in combination with a high positive voidcoefficient further increased the reactor's thermal power. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Net reactivity in a reactor is the sum total of all these contributions, of which the voidcoefficient is but one. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. It must be composed of elements with low neutron capture cross sections to prevent positive voidcoefficient and induced radioactivity. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The voidcoefficient is a measurement of how a reactor responds to increased steam formation in the water coolant. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Reactors whose heat transfer process has the operational property of a negative voidcoefficient of reactivity are said to possess an "inherent safety" process feature. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. This is termed a positive voidcoefficient of reactivity. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The change in reactivity caused by a change of voids inside the reactor is directly proportional to the "voidcoefficient". From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. This is because it uses light water as a moderator (rather than graphite), has well understood operating characteristics, and has a negative voidcoefficient of reactivity. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. After 1986 absorbers were introduced in the fuel assembly, permanently assuring a negative void coefficient at the cost of higher enrichment requirements of the uranium fuel. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Should coolant circulation fail the neutron moderation effect of the water diminishes, reducing reaction intensity and compensating for loss of cooling, a condition known as negative voidcoefficient. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. It was partially moderated with graphite, but had a negative voidcoefficient due to also using moderation from the coolant water, meaning it was thermally stable. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. However, the negative voidcoefficient can cause an unplanned reactor power increase in events (such as sudden closure of a steamline valve) where the reactor pressure is suddenly increased. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. On the other hand, if a reactor is designed to operate with no voids at all, a large negative voidcoefficient may serve as a safety system. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. It took away the practical fear of the population, but unfortunately all that the scientists continued to do was to talk about rems and rads and positive void coefficients.
