Question

Why is the reactor coolant water kept contained within the primary loop instead of allowing it to mix with the feed water and leave through the cooling tower? it is contaminated and radio active?

Answer 1

Yes, It is contaminated and radio active

Step-by-step explanation:

The coolant in the primary loop is actually in contact with the reactor fuel. So it will have some trace amount of the reactor fuel and all the other radioactive by products like cobalt.

Also the neutrons in the reactor will convert the hydrogen in the water into radioactive tritium. and the oxygen into radioactive nitrogen.

This is why the primary loop water is kept isolated from the feed water.

Answer 2

For the answer to the question above, I the answer is yes, It is both contaminated and radioactive at the same time. That's why they keep the water spinning.I hope my answer helped you. Have a nice day!
