WebIt has a rather small probability for absorbing a neutron, so it is not in itself a significant factor in the reaction rate control. But it has a half-life of about 6.7 hours and decays into xenon-135 (half-life 9.2 hours). The xenon-135 has a very large cross-section for neutron absorption, about 3 million barns under reactor conditions! Web23 de ago. de 2024 · It was poorly-trained control-room operators, who did not understand how the reactor was behaving, who had no clue what it was capable of, and who disabled crucial safety systems and went completely off the script. That could happen anywhere, in any reactor whose owners are more concerned with profits than with safety. $\endgroup$ –
