Sentence examples for void coefficient from inspiring English sources

The void coefficient (VC), moderator temperature coefficient (MTC) and Doppler coefficient remained negative.

(c) Reducing the negative void coefficient of reactivity by, at least, 50%.

However when Th is mixed with U-233, the void coefficient (calculated in 2D) can be positive under some conditions.

In Chernobyl, a key role was played by the "positive void coefficient" of the reactor core and the lack of an adequate containment structure.

With its small reactor core size, large negative void coefficient, and low operating thermal neutron flux, an enhanced xenon stability characteristic is possible.

In the case of the void coefficient, the difference of the results increases at higher void fractions, being the highest at 95%.

This evident need to improve resource-efficiency has stimulated interest in Fast-reactors, and with it, boosted the need to answer many of the remaining safety issues attached to such systems (i.e. coolant positive void coefficients).

Reactivity control is a key challenge due to the reduced worth of neutron absorbers and their detrimental effect on the void coefficients, especially when diluted, as is the case for soluble boron.

Two different approaches are presented with the results of several full-core burnup calculations performed by the Monte Carlo code Serpent 2. The presented results are the multiplication factor changes, delayed neutron fractions, fuel temperature and void coefficients and fissile isotope vectors as well.

The instabilities can be caused by interdependencies between thermal-hydraulic and reactivity feedback parameters such as the void-coefficient, for example, during a pressure perturbation event.

More precisely, we investigated the influence of the outer graphite reflectors on the multiplication factor of the core, the fuel and moderator temperature reactivity coefficients and the void reactivity coefficient for five different molten salts: NaF, BeF2, LiF, ZrF4 and Li2BeF4 eutectic.
