RITEG


Radioisotope thermoelectric generator, as known as RITEG or RTG. The starting power output is 600 kW, the half life about 12 hours.

b possible mod interaction bug

3 years ago

I am investigating why I can't craft plutonium from other mods you have built-in support for. wanted a way to burn off extra depleted uranium so I installed the other linked mods and found I couldn't craft the plutonium from those mods. I also did some math and found out that your RITEG produces 623.... ish GJ of power if left forever. Furthermore, I found that the % set to be auto deconstructed at, exactly relates to the amount of wasted potential energy. I don't know if you intended to have them produce .. 623/ 8= 77.875 times more energy than a single uranium fuel cell. I wonder what they could produce...

A RITEG needs 5 * 8GJ of uranium fuel and in a perfect grid that is .... (5 * 8)+400% efficiency so 558=200GW per RITEG max if the uranium was used in perfect conditions. 623/200~= 3.xxxxx

your base RITEG produces 3x the energy slowly for no disadvantage like a nuclear meltdown.

this is a link to the graph that I used to calculate that 623GJ

I am still looking into why I can't craft Plutonium from the other mods.

Items must have same name, but recipes must have unique names. If some mod adds item "bob-plutonium-fuel-cell", then it will be different from another items, that called just "plutonium-fuel-cell".
And for good compatibility I need the full list of all possible names from all existing mods. Yeah.

Just write the internal name (F5 - F4: show debug description) and I will add compatibility when I have time.

KK, after I get off work I will

are these the item names you are looking for? https://photos.app.goo.gl/rHLGLwn7CdeQUDhC8

Thanks, one item is just "plutonium" (the red one), and another is "plutonium-238" (some green-blue color). I can rename / replace one with another, but it can crush another mod dependencies.
Maybe some recipes to convert one plutonium to another and back.

I put messages about this on both the linked optional mods to this. The 238 is supposed to be from a crafting recipy. But it doesn't appear for my mod set. I am looking into it.

TLDR Schall Uranium Processing is having problems with Nuclear Fuel
I started testing mods these are my results.
1=active mod 0=inactive

Nuclear Fuel: 1
Plutonium Energy: 1
RITEG: 1
Schall Uranium Processing: 1
Result: crafting bugged

Nuclear Fuel: 0
Plutonium Energy: 1
RITEG: 1
Schall Uranium Processing: 1
Result: crafting working

Nuclear Fuel: 1
Plutonium Energy: 0
RITEG: 1
Schall Uranium Processing: 1
Result: crafting bugged

Nuclear Fuel: 1
Plutonium Energy: 0
RITEG: 1
Schall Uranium Processing: 0
Result: crafting bugged

Nuclear Fuel: 1
Plutonium Energy: 1
RITEG: 1
Schall Uranium Processing: 0
Result: crafting working

when Schall Uranium Processing and Nuclear Fuel are active mods RITEG's crafting and nuclear-related crafting don't work.

I added breeder RITEG for Nuclear Fuel integration which can be crafted from breeder fuel cells (from Nuclear Fuel), that require plutonium (not plutonium-238/239).

(updated 3 years ago)

I also did some math and found out that your RITEG produces 623.... ish GJ of power if left forever.

Wolfram alpha says that if you want 40 GJ of energy, and start with a power output of 600KW, that your half life should be about 200000 * log(2) / 3, or about 46209 seconds, (since KW is K joules / sec), or a little over 12 hours.

https://www.wolframalpha.com/input/?i=integral+from+0+to+infinity+of+600*e%5E-%28a*x%29+%3D+40000000%2C+integral+from+0+to+h+of+600*e%5E%28-a*x%29+%3D+20000000

I think, in your math, you made a mistake. You're multiplying 12 by 60 everywhere, not 3600.

I looked at the calculations inside the code, and it uses a figure for the half life of joules * log(2) / watts as the number of seconds for the half life. 40GJ * log(2) / 600KW = 200000 * log(2) / 3 seconds, which is exactly correct.
