3 / 15

What is the significant energy produced in the reactor for years even after a shutdown referred to as?

Core energy

Primary coolant

Dilution process

Decay Heat

4 / 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?

5 / 15

The primary coolant heats the feedwater and causes it to:

Solidify the core

Increase in radiation

Decrease in temperature

6 / 15

A month after the reactor's shutdown, the power produced by the core is approximately:

~ 0.5%

~ 0.125%

~ 1%

~ 0.25%

7 / 15

Immediately upon a Reactor Trip, what percentage of power is the core producing?

~ 7%

~ 0.5%

~ 1%

~ 25%

8 / 15

What are the radiological conditions during normal operations characterized by?

Stable and low levels of radiation across the entire plant

No detectable particulates or iodines

Only noble gases without any radiation

Extremely high dose rates due to gamma radiation from fission and Nitrogen-16 neutrons

9 / 15

Which part of the plant delivers borated water to the Steam Generators?

Reactor Coolant Pump

Main Turbine

Two hot legs

Chemical Volume & Control System

10 / 15

The power being produced by the core after a reactor trip decreases:

Incrementally by 1% daily

By half for every time interval

By a quarter each day

Two-fold every week

11 / 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
