A nuclear explosion is designed to deliver `1 MW` of heat energy, how many fission events must be required in a second to attain this power level. If this explosion is designed with a nuclear fuel consisting of uranium `235` to run a reactor at this power level for one year, then calculate the amount of fuel needed. You can assume that the calculate the amount of energy released per fission event is `200 MeV`.

Explanation

To solve the problem step by step, we will break it down into two parts:

### Part A: Calculate the number of fission events required per second to attain 1 MW of power.

1. **Understanding Power and Energy**:
- Power (P) is defined as the rate of energy transfer. It is given as 1 MW, which is equivalent to \(10^6\) joules per second.
- Therefore, \(P = 10^6 \, \text{J/s}\).
