decay_heat_with_nuclear

It's a easy way to get nuclear fuel decay heat when it remove from reactor core. Using 3 method ASB9-2, ANS-1973 and ANS-1979 to calculate it.

Install this gem and require it

gem install decay_heat_with_nuclear

require 'decay_heat_with_nuclear'

You need a HASH

The hash will like this:

hash = {
          ts: array,
          t0: array
       }

where ts is Time after remove (sec), t0 is Cumulative reactor operating time (sec)

Calculate from this gem

DecayHeatWithNuclear.run(hash)

and you will get the hash data like:

output_hash = {
                ans1979: { ts: array, P/P0: array },
                ans1973: { ts: array, P/P0: array },
                asb9_2:  { ts: array, P/P0: array, P/P0_without_k: array }
              }

It's interesting about ASB9-2, in this paper:

In calculating the fission produce decay energy, a 20% uncertainty
factor (K) should be added for any cooling time less than 10e3 seconds,
and a factor of 10% should be added for cooling times greater than 10e3
but less than 10e7 seconds.

How about ts is greater than 10e7 sec? Therefore, using two answer. Ths answer P/P0 a factor of 10% should be added, and P/P0_without_k without 10% when ts is greater than 10e7 sec.
