This hot radioactive water flows through tubes in a steam generator. Due to the requirement to load a pressurized water reactor's primary coolant loop with boron, undesirable radioactive secondary tritium production in the water is over 25 times greater than in boiling water reactors of similar power, owing to the latter's absence of the neutron moderating element in its coolant loop. The steam is used to power a turbine generator. This study focuses on three representative PWRs and extrapolates the plant-specific findings for their generic applicability. This is done through uranium enrichment—which increases the concentration of Uranium-235 from 0.7% to around 4%. Maps, tools, and resources related to energy disruptions and infrastructure.
