Increase in radiation

Solidify the core

3 / 15

When the plant is operating, how many loops are working together to take the heat generated in the core from fission and convert it into electrical energy?

4 / 15

Which system maintains the balance by receiving Letdown at the current Reactor Coolant System boron concentration and Charging back water into the Reactor Coolant System at a slightly lower concentration?

Circulating Water Loop

Secondary Loop

Chemical Volume & Control System

Primary Loop

5 / 15

What serves as the SECOND Fission Product Barrier?

The primary piping

Main Turbine
