WebDuring power changes at power operation mode (i.e., from about 1% up to 100% of rated power), the temperature reactivity effects play a very important role. As the neutron population increases, the fuel and the moderator increase their temperature , which results in a decrease in reactivity of the reactor (almost all reactors are designed to ...

WebJul 20, 2024 · In general, resonance effects are more powerful than inductive effects. Because the inductive effect depends on electronegativity, fluorine substituents have a more pronounced p K a -lowered effect than chlorine substituents. Induction is the redistribution of electron density through a traditional sigma bonded structure according to the electronegativity of the atoms involved. The inductive effect drops across every sigma bond involved limiting its effect to only a few bonds. Conjugation is a redistribution of electron density similar to induction but transmitted through interconnected pi-bonds. Conjugation is not only affected by electronegativity of the connected …

There are more esoteric electronic effects but these are among the most important when considering chemical structure and reactivity.

WebNet difference in reactivity between two power operating states characterized by core temperature and moderator density (or void fraction) Power defect in reactivity is a static reactivity balance between two operating states which integrates impacts of Doppler and moderator density reactivity feedback Start with simplified reactivity balance: WebReactivity and stability are two opposing concepts. The more stable a molecule is, the less it wants to react. ... So we have these two competing effects, induction versus resonance. And whichever one is going to win- we can think about this balance for helping us to determine the reactivity of our carboxylic acid derivatives. So we start with ...
