Deliver fuel and run the refueler crane

Refueling opens when fuel falls below about 80 percent. Call it earlier. Around 83 percent, Reactor Operations should radio Plant Maintenance. Below about 75 percent the core cools too fast at the normal 55 percent rods, and operators have to raise rods to about 36 percent or less to hold temperature.

Only Plant Maintenance normally drives the crane. Reactor Operations or the Shift Manager can drive it when maintenance is short-staffed. Only Reactor Operations can press the refueler panel buttons, so an operator still has to be there.

Deliver the rods

Logistical Operations unlocks at 8,000 Plant Maintenance XP or the 100 Robux gamepass. The M41 DOE Nuclear truck is available at 0 logistics XP and carries up to three fuel pallets.

1. Spawn the M41 DOE Nuclear at the depot.
2. Drive the right lane toward the factory and take the gravel path across the tracks.
3. Back into the yellow loading rectangle.
4. Press J to park, get out, and use the panel that lowers fresh rods into the bed. J also stops the empty-vehicle despawn timer. Unparked vehicles are described as disappearing after about 30 to 40 seconds.
5. Wait until the cable lets go, then drive back through the personnel checkpoint.
6. Take the logistics bypass and the left tunnel into the reactor hall.
7. Park under the crane with J. If another truck is in the bay, wait outside.

The same logistics team also moves diesel and Bloxy Cola. Later vehicles on that team include the DO Supply LLUV at 3,000 XP, the M41 Cargo 41Z and Kat-TL HTV at 10,000 XP, and the Chief Supply Officer at 600,000 XP.

Crane cycle

The on-screen prompt is the safest click path. The written cycle is:

1. Sit at the crane console.
2. Move the loader to new-fuel storage. Lock it, turn driving off, select an empty FRS slot, and press swap rods.
3. Unlock, drive to the marked used rod in the core, lock again, and swap into an empty slot.
4. Select the slot that now holds the fresh rod and swap again.
5. Drive to the water, select the used rod, and swap it out.
6. Repeat until the delivered pallets are in the core.

Press F when a prompt asks you to attach a fresh assembly to the hoist. Do not drive off while a cable is still attached at the factory.

Who does what

Logistics owns the truck. Maintenance owns the crane when enough technicians are on. Reactor Operations authorizes the swap and watches temperature while fuel is low. If fuel is falling during a power order, finish or abandon the order on purpose. Do not chase excess with rods while the crane is mid-swap unless the core is actually stalling.
