Question

In the case of nuclear disaster, which of the following options for cooling the nuclear reactors may be adopted? 1. Pumping of water to the reactors. 2. Use of boric acid. 3. Taking out the fuel rods and keeping them in a cooling pond. Select the correct answer using the code given below:
A. 1, 2 and 3 B. 1 and 3 only C. 3 only D. 1 and 2 only

Answer 1

Solution : In the case of nuclear disaster, the following options of cooling the nuclear reactors may be adopted is  pumping of water to the reactors and use of the boric acid , so option D is correct.

• To cool the nuclear reactor we pump the water to the reactor , this method is very simple , push the water past the nuclear core and carry the heat somewhere else. The chain reaction that runs the reaction will stop , and the residue left is the radioactive material , it will continue to give the heat for the long time.
• Boric acid plays a very important role in cooling the nuclear reactor ,  in pressurized water reactors (PWRs) , boric acid (B-10 isotope is added to the coolant system as a neutron attacker  to control the rate of nuclear reactions and energy that generated.

Answer 2

D. 1 and 2 only are the appropriate answer.

Explanation:

• To cool the nuclear reactor we pump the water into the reactor, this approach could be very simple, push the water beyond the nuclear center and deliver the warmth someplace else.
• The chain response that ruins the response will stop, and the residue left is the radioactive material, it'll maintain to provide warmth for an extended time.
• Boric acid performs a totally vital function in cooling the nuclear reactor, pressurized water reactors (PWRs), and boric acid.
• B-10 isotope is introduced to the coolant machine as a neutron attacker to manipulate the charge of nuclear reactions, and electricity is generated.
