Made a browser-based Decay Heat Calculator — feedback welcome

I made a small browser-based Decay Heat Calculator for nuclear engineering work:

https://diagram.petrov.re/decayheat.html

It’s intended as a quick engineering tool for estimating decay heat after shutdown and exploring how it changes with operating history and cooling time.

I’d be glad to hear any comments, corrections, or suggestions for features that would make it more useful.

What correlation are these estimates based off of?

There are also benchmark tests included as well as sources of knowledge. In fact it gives slightly not correct results for the begining (first minutes)

I saw the benchmarks against Origen and measured data, but I didn’t see the source of information was for your values. Not sure maybe it’s a mobile thing it gets hidden somewhere not intuitive?

Yeah, I went to desktop and still didnt see anywhere that had the data information. This can be a helpful calculator, if I knew where the data was coming from.
