Configuration

NeroPower's settings live in config/neropower.properties, managed by Neroland Core's shared config system: the file is created with defaults and comments on first run, every value is range checked, and /neroland config reload applies changes without a restart. Every key below is server-authoritative — on a multiplayer server the server's values win and are synced to clients. NeroPower never reads nerotech.properties; NeroTech's thermal balance stays NeroTech's. The one exception is telemetryEnabled (see Privacy), which is client-local: each player and server decides for themselves.

Permille values are thousandths: 600 = 60 %.

Master toggles

Key	Default	Range	What it does
`overloadEnabled`	`true`	—	`true`: an unmanaged reactor walks the full failure ladder and destroys itself at the top. `false` (survival-friendly): the ladder is pinned at Unstable — throttled output and alarms, never a failure action.
`terrainDamageMode`	`auto`	`on` / `off` / `auto`	Whether a reactor failure breaks blocks. `auto` = off on a dedicated server, on in singleplayer and LAN. `off` keeps the blast's damage and knockback (and the machine is still lost) but breaks nothing.
`failureRadiusCap`	`8`	1–16	Hard cap on any failure blast radius, whatever the machine asks for.
`transmissionEnabled`	`true`	—	`true`: beamed power links and transfers. `false`: the blocks place but every beam stays dark.
`planetEfficiencyEnabled`	`true`	—	`true`: the Stirling Generator's cold-face bonus scales with how cold the local ambient is (NeroTech's planet ambient): `bonus × (1000 + clamp(−ambient × 5, 0, 1000)) ⁄ 1000` — ambient −80 on a cold planet gives +40 % on top of the bonus, ambient 0 or warmer none. `false`: the flat bonus everywhere. The RTG ignores it (decay is the same on every world).

Failure ladder

See Failure Stages.

Key	Default	Range	What it does
`failureWarningPermille`	`600`	1–1000	Heat (permille of heat capacity) at which a reactor enters Warning (alarm state, full output).
`failureUnstablePermille`	`800`	1–1000	Heat at which a reactor enters Unstable (output scaled by `unstablePenaltyPermille`, warning alert to the owner). Must exceed `failureWarningPermille`.
`failureFailurePermille`	`1000`	1–1000	Heat at which a reactor fails (its failure action runs). Must exceed `failureUnstablePermille`; ignored when `overloadEnabled` is `false`.
`failureHysteresisPermille`	`50`	0–1000	A stage is only left downwards once heat drops this far below the threshold that entered it.
`failureMinDwellTicks`	`100`	0–72000	Minimum ticks a reactor stays in each stage before it may climb to the next (100 = 5 s).
`unstablePenaltyPermille`	`600`	0–1000	Output multiplier while Unstable (600 = 60 %). Failure always yields 0.

Fission reactor

See Fission Reactor.

Key	Default	Range	What it does
`fissionNePerRod`	`120`	1–100000	Nominal NE/tick one fresh Fuel Rod contributes at 100 % of the burn-up curve; the core sums every loaded rod, then scales by control rods, preset, upgrades and the failure ladder.
`fissionHeatPerRodPerTick`	`6`	0–10000	Heat one rod adds per tick at 100 % of its heat factor (heat factor = output factor + 200 permille). Control rods reduce it in step with output.
`fissionBurnupPerTick`	`8`	1–1000000	Burn-up a loaded rod gains per tick, in permille ×1000 (8 = a rod lasts about 125,000 ticks, ~104 minutes, at Balanced).
`fissionBurnupCurve`	`0=1200,200=1000,600=800,1000=300`	text	Output factor (permille of nominal) by rod burn-up (permille), as `burnup=factor` knots interpolated linearly. Fewer than two valid knots falls back to the default.
`fissionControlRodPermille`	`150`	0–1000	Output and heat reduction per Control Rod Assembly inside the shell; the factor never drops below 15 %.
`fissionPoisonPerTick`	`2`	0–1000	Neutron poison gained per tick while the core runs hot: full output, every usable slot loaded, and the effective control-rod factor above `fissionPoisonRodThresholdPermille` (0 disables poisoning).
`fissionPoisonRodThresholdPermille`	`900`	0–1000	Poison only builds while the effective control-rod factor (permille; 1000 = no assemblies) is strictly above this line. With the defaults one Control Rod Assembly (850) or a SCRAM (150) keeps the core steady and poison decays.
`fissionPoisonDecayPerTick`	`3`	0–1000	Poison shed per tick whenever the core is not accumulating it.
`fissionPoisonStallPermille`	`900`	1–1000	Poison level at which the core stalls (the xenon pit) until it has decayed 300 below this line.
`fissionScorchEnabled`	`false`	—	`true`: a fission failure also leaves a scorch zone that hurts living creatures for `fissionScorchDays` real days.
`fissionScorchDays`	`3`	1–365	Real (calendar, UTC) days a scorch zone persists.
`fissionScorchRadius`	`6`	1–32	Half-edge (blocks) of the cubic scorch zone centred on the failed reactor.

Battery banks

See Battery Banks.

Key	Default	Range	What it does
`batteryCellCapacityBasic`	`500000`	1000–100000000	Basic Battery Cell capacity (NE).
`batteryCellCapacityAdvanced`	`2000000`	1000–100000000	Advanced Battery Cell capacity (NE).
`batteryCellCapacityElite`	`8000000`	1000–100000000	Elite Battery Cell capacity (NE).
`batteryCellIoBasic`	`1000`	1–1000000	Basic Battery Cell maximum insert / extract per tick (NE/t).
`batteryCellIoAdvanced`	`4000`	1–1000000	Advanced Battery Cell maximum insert / extract per tick (NE/t).
`batteryCellIoElite`	`16000`	1–1000000	Elite Battery Cell maximum insert / extract per tick (NE/t).
`bankScanRadius`	`2`	1–4	How far (blocks, each axis) a Battery Bank Controller looks for connected cells: 1 = 3×3×3, 2 = 5×5×5, … 4 = 9×9×9.
`bankMaxIoCap`	`64000`	1–10000000	Hard cap on a bank's pooled insert / extract per tick; otherwise min(member cell I/O) × member count.
`bankPriorityThresholdPermille`	`300`	0–1000	Priority Source mode: a bank only pushes into a neighbour whose own buffer is below this fill. Buffer mode ignores it.
`bankCapacityMilestone`	`32000000`	1000–1000000000000	Pooled capacity (NE) at which a bank opens its owner's `neropower:bank_capacity` milestone record — the Power Bank quest signal. It gates nothing.

Beamed power

See Beamed Power.

Key	Default	Range	What it does
`beamRange`	`128`	8–512	Maximum straight-line distance (blocks) a transmitter or relay may beam to its target.
`beamLossPermillePerBlock`	`3`	0–100	Loss per block of distance (permille): delivered = sent × (1 − loss/1000)^distance. 3 = about 68 % delivered at 128 blocks; 0 = lossless.
`beamTransferPerPass`	`2000`	1–1000000	NE a transmitter or relay sends per pass, before loss.
`beamCheckIntervalTicks`	`5`	1–40	Ticks between passes; each pass re-checks line of sight, moves energy and damages anything in the beam.
`beamDamage`	`0.5`	0.0–10.0	Damage (half-hearts) dealt every pass to living creatures standing in an active beam; 0 disables the hazard.
`beamMaxHops`	`8`	1–32	Longest relay chain a single pass follows before it stops (loop guard).
`beamCrossDimension`	`false`	—	`true`: a transmitter may target an Orbital Receiver in a space dimension from another dimension, paying `beamOrbitalHopLossPermille` instead of distance loss.
`beamOrbitalHopLossPermille`	`300`	0–1000	Fixed loss of a cross-dimension orbital hop (300 = 70 % delivered).

RTG and Stirling

See RTG and Stirling.

Key	Default	Range	What it does
`rtgNePerTick`	`30`	1–10000	NE per tick a Radioisotope Generator produces from a fresh Isotope Pellet; halves every `rtgHalfLifeDays`.
`rtgHalfLifeDays`	`20`	1–365	Half-life of a pellet in in-game days (1 day = 24,000 ticks).
`rtgCutoffPermille`	`50`	1–999	A pellet is spent once its output falls below this permille of `rtgNePerTick` (50 = 5 %, about 4.3 half-lives).
`rtgSpentPelletPollution`	`200`	0–100000	Pollution burst (NeroTech's regional pollution, never attributed to a player) recorded per Spent Isotope Pellet destroyed as a dropped item — fire, lava, cactus, explosion. 0 disables it.
`stirlingNePerHeatUnit`	`15`	1–1000	NE a Stirling Generator produces per unit of heat it draws.
`stirlingMaxDrawPerOp`	`8`	1–1000	Hard cap on the heat drawn from a neighbour in one tick.
`stirlingDrawPermille`	`100`	1–1000	Share (permille) of the hot neighbour's gradient above ambient drawn per tick.
`stirlingColdFaceBonusPermille`	`500`	0–1000	Output bonus while touching a cold sink (water, ice, snow or a NeroTech Radiator); without one the usable gradient is halved. Scaled by the local ambient when `planetEfficiencyEnabled` is on.

Privacy

Key	Default	Range	What it does
`telemetryEnabled`	`true`	—	Anonymous crash reports for errors in NeroPower code (Sentry, EU servers; no names, UUIDs, IPs or world data). On by default; set `false` to opt out (takes effect on restart). Client-local, never synced. See Privacy.
