Final answer:
Operation of a nuclear facility subjects the Registrants to risk due to radiation, thermal and pressure hazards, and radioactive waste.
Step-by-step explanation:
Operation of a nuclear facility subjects the Registrants to risk due to several factors:
- Radiation: During the operation of a nuclear reactor, it produces neutrons and other radiation. Even when shut down, the decay products remain radioactive. Therefore, operating personnel must be protected from the harmful effects of radiation.
- Thermal and Pressure Hazards: An operating reactor is thermally very hot, and high pressures result from the circulation of coolant through it. Thus, a reactor must withstand high temperatures and pressures, posing risks to the Registrants. Special shielding and containment systems are in place to minimize these hazards.
- Radioactive Waste: Nuclear power facilities produce high-level radioactive waste, including used nuclear reactor fuel. The storage and handling of this waste require multiple containment measures. Improper handling or storage of radioactive waste can pose risks to the environment and human health.
