What does RTP stand for, and what does it describe?

• A. Reactor Thermal Pressure, the maximum pressure in the core.
• B. Rated Thermal Power (RTP), the total reactor core heat transfer rate to the reactor coolant of 100 kWt.
• C. Reactor Energy Transfer, the rate of heat transfer from the core to the environment.
• D. Rated Thermal Power, the maximum heat generated by the core.

Answer: (B)

Rated Thermal Power describes the total rate at which the reactor core transfers heat to the reactor coolant. This is the plant’s thermal power rating, typically given in kilowatts thermal or megawatts thermal, and it defines the maximum continuous power the reactor is designed to remove through the cooling system. In this sense, RTP is about the heat that must be carried away by the coolant to keep the core within safe temperatures. It’s not about the pressure in the core, and it’s not simply the heat that eventually reaches the environment. While, at steady operation, the heat generated by the core is removed by the coolant, the term focuses on the rate of heat transfer to the coolant itself, which is why it’s described as the rated thermal power delivered to the cooling system.
