SUMMARY
Nitrogen plays a crucial role in Pressurized Water Reactors (PWR) primarily through the unstable isotope N-16, which serves as an indicator of reactor power. N-16 achieves equilibrium activity rapidly, approximately within one minute, due to its half-life of 7.16 seconds. Its activity is directly influenced by the fast neutron flux, which correlates with the fission rate. PWRs maintain a slightly reducing water chemistry to minimize crud transport, with pH levels typically ranging from 6.9 to 7.4.
