Fusion Reactor's Ignition Stops Every Time the Server is Started #7957

Open UnknownSerhan opened 6 months ago

UnknownSerhan commented 6 months ago

Issue description

Duplicate of https://github.com/mekanism/Mekanism/issues/7587, but happening in 1.20.1. I am using D-T Fuel fusion reactor, used lasers to ignite it (last issue was more about "resistive heater ignited" fusion). Everything related to fusion is stored in a single chunk and all chunks are loaded by a dimensional stabilizer. Ran save-all command before stopping the server. 2023-12-12_23 37 39

When the ignition stops, all reactor data is still stored inside (plasma and case heat etc), meaning just the ignition stops.

Steps to reproduce

  1. Build a fusion reactor in a single chunk. Also make sure fuel is in the same chunk too.
  2. Ignite the reactor with lasers.
  3. Chunkload the chunk of the reactor via any way.
  4. Restart the server.
  5. Join the server, the fusion ignition will be gone but all the NBT data will be still there.

I can confirm this bug. It seems the multiblock has to re-form every time the server restarts, which can kill the ignition. With a high enough injection rate of deuterium and tritium, re-ignition happens automatically. With D-T fuel, re-ignition does not happen without inserting another hohlraum. Also, water cannot be inserted into the fusion reactor if only D-T fuel is used.

jlp1528 commented 6 months ago

There is no workaround for the issues I have listed, as feeding deuterium and tritium vs D-T fuel are mutually exclusive upon (re)forming the multiblock and the water is removed. Same MC and Mek versions.

Same issue. Spent 3 days trying to get this to work and researching every reason why it wouldn't.

Doesn't matter if I send D-T fuel, Deuterium and Tritium, or all of the above.

My reactor would ignite, but would not consume ANY fuel.

With an ultimate gas tank on reactor port normally this creates a buffer which gives time for AE2 to initialize. Since then, I no longer have any problems during a server restart. But it is known that ATM 8, 9 also had this "bug"

Unfortunately the issue occurs even with a full ultimate chemical tank feeding fuel to the reactor in the same chunk. So yes it is still a valid bug. We will see if 1.21 will have it, it probably will.
