Both calculators run independently β change the inputs on either side to compare results.
Nuclear
Nuclear Waste Heat Calculator
Estimate the decay heat power still being generated in a shutdown nuclear reactor or spent fuel assembly using the ANS-5.1 standard approximation. Used for designing cooling systems, spent-fuel pool sizing, and emergency core cooling analysis.
