if one neutron initiates a fission event that produces two neutrons in the products, how many new reactions can now be initiated?\nif each of the neutrons produced in the first fission event then initiates a fission event that produces one neutron in the products, how many new reactions can now be initiated by each neutron?\nhow many neutrons in total were produced by the two fission events described?

Answer

Explanation:

Step1: Determine new reactions from first - fission

One neutron initiates a fission producing two neutrons. Each of these two neutrons can initiate a new reaction. So the number of new reactions initiated is 2.

Step2: Determine new reactions per neutron in second - fission

Each neutron from the first fission initiates a fission producing one neutron. So each neutron from the first fission can initiate 1 new reaction.

Step3: Calculate total neutrons from two fissions

In the first fission, 2 neutrons are produced. In the second - stage fissions (initiated by the 2 neutrons from the first fission), each produces 1 neutron, so 2 more neutrons are produced. The total number of neutrons produced is 2 + 2=4.
