Source sentences:
text: Thus, once the percentage of U-235 (the fissionable isotope of uranium) is too low (such as in natural uranium, where the percentage of U-235 is about 0.72%), then the amount of neutrons getting through the moderator without being abosorbed is not high enough to maintain criticality (the point at which the amount of neutrons being produced is equal to the amount escaping the system or being absorbed but not resulting in fission), and the chain reaction can no longer continue, and the reactor can no longer produce power.
text: The role of heavy water here is to reduce the speed of neutrons that are produced.
text: Both gamma rays and neutrons are produced and distributed in different nuclear reactions within the Heavy Water Zero Power Reactor (HWZPR) core.
