Peak power for nuclear explosions

Click For Summary
SUMMARY

The discussion centers on the calculation of peak power output in the context of nuclear explosions, specifically referencing Iran's nuclear program. The peak power output is derived from energy over time, with the energy graph resembling a simulation. The conversation highlights the importance of understanding the Gaussian pulse shape, akin to reactivity insertion transients in conventional reactors, which typically last several milliseconds, while nuclear explosions exhibit microsecond pulses. The energy is calculated by integrating the pulse amplitude over time, converting joules (J) to kiloelectronvolts (kTeq) for analysis.

I was reading this article http://news.yahoo.com/ap-exclusive-graph-suggests-iran-working-bomb-161109665.html on Iran's nuclear programme and at first thought the numbers on the left (relating to kilotons of energy per second) were off, but then I realized that it relates to peak power output at that specific period of time. How would one calculate this normally? I know all the power equations relating to energy/time, but peak power output other than for peak current and peak voltage in alternating current systems.

The energy graph looks like the result of a simulation, and power is simply its derivative.
 
The power pulse looks like a idealized (Gaussian) pulse, similar to what one uses for a reactivity insertion transient in a conventional reactor. There the pulse for a reactor would be on the order of several milliseconds. If the plot has microseconds, this would be an indication of a nuclear weapon.

The energy is just the pulse amplitude integrated over time. The ordinate could be written in W, in which case the energy would be written in J. One only needs to convert J to kTeq.
