Webb. Reactivity additions from control rod motion or boron concentration changes 6. Explain how the neutron population of a subcritical reactor changes in response to reactivity changes. 2.1.1 Introduction This section represents a summary of basic nuclear physics and nuclear reactor design principles and terminology. WebUnder this reaction, boron will oxidize to boric oxide. At room temperature, boron is chemically inert; It is only reactive with fluorine and oxygen, which will react to form boron trifluoride and boric oxide. However, at high temperatures, the element reacts with almost all metals (excluding tellurium and the noble gases).
WebOct 2, 2015 · Boron-11 has a low cross section for neutron absorption. The size of the nucleus isn't terribly relevant because neutrons are quantum objects and don't have a precise position. The incident neutron will be delocalised and some part of it will almost always overlap the nucleus.
