'''Quality''' is a feature of the [[Space Age]] expansion. It introduces four higher quality levels for all items, structures and equipment with improved attributes. The goal of quality is to allow vertical factory upgrading as alternative to expansion in size. Items of higher quality are created by chance when using quality modules in the producing structure. The two highest quality tiers require technology not available on Nauvis. Different buildings and items can have different attributes that can be upgraded. When hovering over something, the attributes that will be upgraded with quality will be marked with a blue diamond in the tooltip.

While players are required to own Space Age to access this feature, quality is a separate mod, and can be activated independent of most Space Age content.

== Quality tiers ==
There are 5 quality tiers in vanilla gameplay, with tier strength in brackets:
* [[File:quality_normal.png|15px]] Normal (0)
* [[File:quality_uncommon.png|15px]] Uncommon (1)
* [[File:quality_rare.png|15px]] Rare (2)
* [[File:quality_epic.png|15px]] Epic (3)
* [[File:quality_legendary.png|15px]] Legendary ('''5''')

Note that legendary quality represents a 2-tier improvement over epic.

== Technologies ==
Certain tiers of quality cannot be created until they have been researched.

== Quality effects ==
The currently known effects of each level of quality are as follows:
* +30% health
* +30% energy output
* +30% crafting speed
* +30% robot limit (rounded down)
* +30% robot recharge rate (both number and speed, rounded down)
* +30% positive module effects (rounded down for at least quality modules)
* +10% turret range
* +1 tile reach and +2 wire reach on power poles
* +1 equipment grid size (both dimensions)
* Larger inventory (unknown boost size)
* Increased ammo damage (30%?)
* Faster inserters
* Reduced resource depletion on miners (likely multiplicative in effect with productivity)
* +100% (+5 MJ) capacity on accumulators
* Increased output rate on nuclear reactors, boilers, and steam engines/turbines
* Reduced power consumption on beacons
* Larger scan range on radars
* +100% durability on consumable items (repair packs, science packs)
* +5% fork chance on the [[tesla turret]] and tesla ammo for the tesla gun

These effects are per quality strength and additive, a Legendary (5 tier-levels) [[Productivity module 3]] (base +10% productivity) would grant 25% productivity.

Some buildings, such as [[Transport belt]]s and [[Wall]]s, only gain increased health.

== Creating high-quality items ==

There are two ways to create an item with above normal quality: The player must either use ingredient items of the same quality, or use quality modules for a random chance of a higher-quality item.

=== Quality ingredients ===
Recipes that create items have variations for each quality that the item might take. When setting such a recipe in a production unit, an ingredient quality must be selected. For these variations, the set of ingredients required is the same, except that all item ingredients must have the specified quality.

Item ingredient quality requirements are exact, not minimum. For example, one can not combine uncommon [[iron plate]]s with rare [[battery|batteries]] to make an [[accumulator]] of any quality. One must therefore ensure that high-quality items do not clobber belts and starve production units of lower-quality items.

As fluids do not possess any quality, they are exempt from ingredient quality requirements; The same [[lubricant]] can be used to create [[electric engine unit]]s of any quality.

=== Quality modules ===
{{Main|Quality module}}
[[File:quality_module_animated.png|64px|right]]'''Quality modules''' allow crafting machines to produce items of a higher quality than their ingredients. Each module adds 1%/2%/2.5% quality chance to a machine, depending on its tier.

When working out the odds of improving quality, a machine starts with the sum of the quality chance of all its modules. When the machine produces an item, it performs a random roll with that chance to succeed. If it succeeds, the product is upgraded 1 level from its ingredients. If the product was upgraded, the machine repeats this process, now with a constant 10% chance of passing, rolling and upgrading until a roll fails.

For 10% quality chance crafting recipe with all tiers unlocked, this gives the following odds:
{|class="wikitable" style="text-align: center;"
! Input !! [[File:quality_normal.png|32px]] chance !! [[File:quality_uncommon.png|32px]] chance !! [[File:quality_rare.png|32px]] chance !! [[File:quality_epic.png|32px]] chance !! [[File:quality_legendary.png|32px]] chance
|-
| [[File:quality_normal.png|32px]] || 90% || 9% || 0.9% || 0.09% || 0.01%
|-
| [[File:quality_uncommon.png|32px]] || - || 90% || 9% || 0.9% || 0.1%
|-
| [[File:quality_rare.png|32px]] || - || - || 90% || 9% || 1%
|-
| [[File:quality_epic.png|32px]] || - || - || - || 90% || 10%
|-
| [[File:quality_legendary.png|32px]] || - || - || - || - || 100%
|}

For 24.8% quality chance (4x[[File:quality_legendary.png|15px]]Legendary [[quality module 3]]), the odds are instead:
* 75.2% Normal
* 22.32% Uncommon (24.8% Uncommon+)
* 2.232% Rare (2.48% Rare+)
* 0.2232% Epic (0.248% Epic+)
* 0.0248% Legendary

When using quality ingredients as an input, the base quality is the quality of the recipe. You can only use items with the same quality as input.

Quality modules are only required to ''improve'' quality, crafting will always give the base quality of the used items. Additionally, the odds of improving from a given base quality is the same as improving the same number of tiers from Normal quality.

==== Optimal module usage ====
When using [[Assembling machine 3]]s with the goal of converting all input items to Legendary outputs, and feeding non-Legendary items through a [[Recycler]] with 4 quality modules (as recyclers can't take productivity modules), the optimal number of quality and productivity modules is as follows:
* If the quality modules offer less than 15% chance (Normal and Uncommon [[Quality module|T1]], [[Quality module 2|T2]], and [[Quality module 3|T3]]s), use 4 quality modules
* If the quality modules offer 16% (Rare T3s) or 19% (Epic T3s), use 3 quality modules and 1 productivity module
* If the quality modules offer 25% (Legendary T3s), use 2 of each module
* If the quality modules offer ''exactly'' 15% (Legendary T2s):
** When the base quality of the inputs is Epic, use 4 quality modules
** When the base quality of the inputs is Rare, use 4 quality modules
*** Except when your productivity modules have more than +1.5% productivity use 3 quality modules
** When the base quality of the inputs is Normal or Uncommon, use 3 quality modules

It is also more optimal to improve quality on the lead-up to the target output item due to the recycler only giving back 25% of the input items, except for cases where the chosen item has a productivity research available, in which case looping through a recycler is optimal and has no added material cost (ignoring fluids).

== Trivia ==
* Quality is not technically exclusive to player-made entities; Though this does not occur naturally, quality is also allowed on enemies, asteroids, and even the [[player]] character.
** Some enemies with qualities above normal can even be created in regular sandbox gameplay: Big biters, behemoth biters, and big premature wriggler pentapods born from spoiled [[biter egg]]s, [[captive biter spawner]]s, and [[pentapod egg]]s inherit the quality of the spoiled items, with the latter two being possible to craft with quality modules. Furthermore, a starved captured biter spawner will retain its quality upon converting into a hostile biter spawner, with said quality even being inherited by the biters that it will spawn. Should these biters chose to expand, they may also create quality spitters and worms.

Module

2024-11-17T20:34:59Z

Sachertorte: Add crosslinks to dedicated module pages

{{Languages}}
[[File:modules_preview.png|right]]'''Modules''' are items used to enhance existing buildings' capabilities. They are expensive, require appropriate [[research]], and are produced slowly, but can eventually greatly improve the efficiency of a factory.

Quick usage summary:
*For more products per second a speed module should be used.
*For more products per input resource a productivity module should be used.
*For more products per watt of energy an efficiency module should be used (except in rare cases when productivity modules are also used - then a speed module might be better).

Note that changing a machine's energy consumption directly affects how much pollution the machine generates. This is the case because the pollution production rate is directly linked to the machine's energy consumption, so this applies even when power is produced in a pollution-free way.

== Types of modules ==

There are three types of modules in ''Factorio'', each with 3 tiers of effect. Higher tiers have stronger effects but are more expensive. Note that the machine's properties (speed, energy consumption and pollution) cannot be reduced below 20% of the original value.

=== Speed module ===
{{Main|Speed module}}
Speed modules increase the speed and energy consumption of a machine.

{| class="wikitable"
|-
! Module !! Speed bonus !! [[Electric system|Energy]] consumption
|-
| {{Icon|Speed module}} || +20% || +50%
|-
| {{Icon|Speed module 2}} || +30% || +60%
|-
| {{Icon|Speed module 3}} || +50% || +70%
|-
|}

Advantages & Disadvantages:

* Increases speed of machine. 
* If used with productivity modules, it can increase the efficiency of the machine in terms of items produced per joule (or items produced per pollution generated). 
* Increases energy use per cycle (exceptions exist). 
** Increased energy usage means increased pollution generation (pollution depends on power usage). 

----

=== Productivity module ===
{{Main|Productivity module}}

Productivity modules add a purple "productivity bar" when placed inside item-producing buildings and [[lab]]s. If the productivity bar is already present through completed research, the modules will simply speed up the bar. Each time the machine finishes crafting the recipe it is set to, an amount is added to the bar equal to the percentages of the productivity modules inside the machine. When the bar reaches 100%, an extra set of products is immediately generated without consuming any resources.

Productivity modules can only be used in machines that are set to make [[:Category:Intermediate_products|intermediate products]]. These are all the ores mined by electric drills, the stone brick (and anything else smelted in a furnace) and some of the items listed in the intermediate products tab. Exceptions to the items listed in this tab are the recipes that fill/empty a barrel. Productivity modules cannot be placed in [[beacon]]s either. When a recipe uses the same item as an input and output (e.g. [[coal liquefaction]] and the [[kovarex enrichment process]]) the productivity bonus only applies to the net product [https://www.factorio.com/blog/post/fff-256].

{| class="wikitable"
|-
! Module !! Productivity bonus !! [[Electric system|Energy]] consumption !! Speed !! [[Pollution]] multiplier
|-
| {{Icon|Productivity module}} || +4% || +40% || -5% || +5%
|-
| {{Icon|Productivity module 2}} || +6% || +60% || -10% || +7%
|-
| {{Icon|Productivity module 3}} || +10% || +80% || -15% || +10%
|-
|}

Advantages & Disadvantages:

* Creates an additional free item occasionally. 
* Increases energy use per cycle. 
* Increases pollution generated. 
* Slows the machine. 

----

=== Efficiency module ===
{{Main|Efficiency module}}

Efficiency modules reduce the required electricity to run the machine. The lowest amount of energy that efficiency modules can be used to achieve is 20% of the machine's base energy usage.

{| class="wikitable"
|-
! Module!! [[Electric system|Energy]] consumption
|-
| {{Icon|Efficiency module}} || -30%
|-
| {{Icon|Efficiency module 2}} || -40%
|-
| {{Icon|Efficiency module 3}} || -50%
|-
|}

Advantages & Disadvantages:

* Reduces energy use per cycle. 
** Decreased energy usage means decreased pollution generation (pollution depends on power usage). 
* Cannot lower energy usage below 20%. 
* If used with productivity modules, sometimes the efficiency gain is lower than what a speed module could achieve. 

=== Quality module ===
{{Main|Quality module}}
{{About/Space age}}
Quality modules increase the chance of items being produced in higher qualities, which in turn grant bonuses which makes items and buildings work more efficiently. Higher quality items have a lesser chance of being created. Note that quality modules themselves can be made with higher qualities, which further increases the chance of higher quality products being made.

{| class="wikitable"
|-
! Module !! Quality bonus !! Speed
|-
| {{Icon|Quality module}} || +1% || -5%
|-
| {{Icon|Quality module 2}} || +2% || -5%
|-
| {{Icon|Quality module 3}} || +2.5% || -5%
|-
|}

Advantages & Disadvantages:

* Can provide higher quality items. 
* Quality modules themselves can have higher quality. 
** Modules with higher qualities have larger bonuses, further increasing the chance of better items being made. 
* Slightly decreases speed of buildings. 
* Not all higher quality items have bonuses. 

== Usage tips ==

As a rule, the effects of multiple modules are '''additive, not multiplicative''', meaning they don't have diminishing returns (except that consumption is capped to -80%), so if an assembler is making 2 items per second, adding one speed module 3 (+50% speed) will increase item production by 1/s, and a second speed module 3 will increase production by another 1/s. Consumption modifiers work the same way, for example if a machine is consuming 180kW, the first efficiency module 1 will reduce energy use by 54kW, the second will also reduce energy use by 54kW. There is no difference between putting two speed module 1's in one machine and two efficiency module 1's in a second machine, compared to putting one of each in both machines - in both cases the total items produced per second and average energy required per item is identical.

There is however synergy between productivity modules and speed modules, productivity modules reduce crafting speed which lowers the production rate of items and increases the energy consumed per item, the speed bonus from speed modules increases production rate of items and lowers the energy consumed per item - in fact when dealing with productivity modules, the reduction in energy consumption from the increased speed from speed modules can be greater than the increased energy consumption. For detailed calculations on the synergy between productivity modules and speed modules refer to [http://www.factorioforums.com/forum/viewtopic.php?f=5&t=5705 this discussion] as well as [https://forums.factorio.com/viewtopic.php?f=16&t=59989 this warning].

Filling the device with '''speed modules''' is useful when a resource is infinite but the amount of resource pools is low. The best example would be '''oil deposits'''. Another good place to use speed modules would be for assembly machines which make products that take a long time to make, for example engine units. Using speed modules allows more compact setups, because one machine can provide materials to more consumers than normal. If used together with productivity modules, they can also increase efficiency (in terms of items produced per watt or per pollution generated) of a machine.

Filling devices with '''productivity modules''' is recommended when resources are scarce. An example would be more advanced products not being produced enough due to bottlenecks. It will take longer and more energy, but the overall amount of products per time will be higher. Productivity is especially useful in recipes that consume a lot of resources per second such as [[electronic circuit]]s, as this will result in a lot of free items being created and quickly cover the cost of the module. Also by saving the need to mine ore, smelt plates and process intermediates for those free items the additional energy cost can be easily covered.

Filling devices with '''efficiency modules''' is recommended for electric furnaces as these use a lot of power. Note that making higher level efficiency modules are not worth it in terms of power saved vs materials used to build a [[solar panel]] setup with same power output so the only incentive is to further reduce pollution or space utilization. Modules are also able to control [[pollution]], as '''pollution depends also on [[Electric system|energy]] usage'''. So reducing a machine's energy usage by 40% with a efficiency module 2 will also reduce its pollution by 40%. Beware as this also works vice versa! Also note that if you're using productivity modules, a speed module can sometimes provide better efficiency gains due to the fact that the machine will now be producing much more items per second. Efficiency modules also generally don't work well in beacons.

=== Examples of usage ===
[[Electric furnace]]s are huge power hogs at 180 kW per furnace. 1 basic efficiency module reduces it by 54 kW (−30%) – almost a [[solar panel]] worth of power. [[Electric mining drill]]s normally create 10 units of [[pollution]], using 3 basic efficiency modules on them reduces their pollution production by 80% to 2 units per minute.

Using productivity module 3s in the [[rocket silo]] reduces the total resource cost for 1 rocket launch by almost 30%, saving 26k copper ore per rocket launch.

Sachertorte:

== Template for quality-affected stats ==

Writing this here because I need to write it somewhere.

I went ahead and made a template for when the same property varies based on quality. (Example: {{Quality|Small number|Not so small number|Decent number|Big number|Insane number}}.) Not sure if this is how we're gonna handle it (I've never been one to make good decisions :b), so it won't bother me if we wind up doing something completely different. I've already added it to the [[electromagnetic plant]] infobox (not sure if that was a good idea...), so you can see it there in practice if you need to. However, I don't really want to take it any further if I'm the only one who thinks this is a good idea. So, any thoughts? - [[User:Tecanec|tecanec]] ([[User talk:Tecanec|talk]]) 13:07, 28 October 2024 (UTC)
: Thanks for the initial implementation and the example usage! I made some adjustments and I think it's good to go now :D -- [[User:Bilka|Bilka]] ([[User talk:Bilka|talk]]) - Admin 21:51, 28 October 2024 (UTC)

== Optimal module usage ==
How exactly is the optimal module usage calculated? I know the list only applies to it's usage in Assembler 3's, but with the new special buildings from other planets, chemical plants, and other various machines, I feel like it would be much better to break down what exactly the formula is in a general sense so we can apply it to every machine, instead of only getting the answers for a single machine. [[User:Brin|Brin]] ([[User talk:Brin|talk]]) 00:07, 13 November 2024 (UTC)

: Agreed with this - even for one machine, it seems incredibly un-useful to present these stats on the page as absolute truth without showing any workings. I'd rather have this section removed from the wiki than blindly trust it. [[User:Sachertorte|Sachertorte]] ([[User talk:Sachertorte|talk]]) 18:29, 17 November 2024 (UTC)

Nuclear reactor

2024-11-11T22:53:12Z

Sachertorte: Format Celsius units consistently

{{Languages}}
{{:Infobox:Nuclear reactor}}
The '''nuclear reactor''' generates heat by burning [[uranium fuel cell]]s. The heat can be used in a [[heat exchanger]] to produce steam which can be used to generate power. Unlike other forms of power generation, it is load-independent – each fuel cell will always be used completely in 200 seconds, regardless of load or the temperature of the reactor. To prevent wasting fuel, excess power can be stored in [[accumulator]]s, excess steam can be stored in [[storage tank]]s.

Instead of completely consuming the fuel, burning fuel in a nuclear reactor results in [[used up uranium fuel cell]]s. These used up cells can be [[nuclear fuel reprocessing|reprocessed]] in a [[centrifuge]] to get back some of the uranium used to create the fuel cells.

Nuclear reactors have a heat capacity of 10 MJ/℃. Thus, they can buffer 5 GJ of heat energy across their working range of 500℃ to 1000℃, and require 4.85 GJ of energy to warm up from 15℃ to 500℃ when initially placed.

== Neighbour bonus ==
Reactors receive a bonus for adjacent operating reactors, which increases their effective thermal output by 100% per each such link. For example, two reactors operating next to each other will output a total of 160 MW of thermal energy, with each reactor producing 40 MW base and receiving 40 MW of neighbour bonus.

The Neighbour bonus only applies if:
* 2 reactors are directly next to eachother with all 3 heat connections directly connecting the two.
* Both reactors are fueled.

=== Double-row layout ===
The most efficient practical layout is an aligned double row of arbitrary length (number of reactors as needed). For even numbers of reactors, the total output of the array is <code> 160n − 160 MW</code> (where ''n'' = total number of reactors, and assuming all are fueled). Splitting the row, while possibly logistically beneficial, reduces total power output by 160 MW per split.

Odd numbers of reactors are inefficient in maximizing the bonus, but, if needed, the odd reactor should be aligned with one of the rows. Offsetting the longer row instead would not gain the extra reactor any bonus, while the reactor on the other end of the same row would lose its bonus as well. Placing the odd reactor between the ends of aligned rows would also lead to one fewer bonus, and also make the design un-tileable.

In any case however, such concerns are unlikely to arise until one has a very large base, as the individual output of reactors is massive, particularly with neighbour bonuses. As an example, a 5×2 reactor grid would produce 1,440 MW (1.44 GW), the equivalent of 1,600 steam engines, or 24,000 solar panels.

=== Square layout ===
Theoretically, a perfectly square grid of reactors with no spaces between would provide maximum bonus, as it minimizes the number of reactors with unlinked sides. This setup produces <code>200n − 160×sqrt(n) MW</code> (where ''sqrt(n)'' is the square root of the number of reactors).

However, while the heat pipe links will allow energy flow from reactors within the square, with no room around inner reactors, there will be no way to insert and remove fuel cells except manually (heat pipes are traversable by the player), which makes this setup impractical.

Furthermore, the gains compared to the double-row design are not large. After some calculation, one arrives at the expression for the ratio of the two (double-row design in denominator) as <code>(1.25n − sqrt(n)) ÷ (n − 1)</code> which evaluates to, for example, 1 for 4 reactors, 1.07 for 16 reactors, 1.16 for 100 reactors (considering only numbers that both an equal-length double row and a square can be built from), and so on. In the limit (infinite number of reactors), the ratio approaches 1.25 as the edge corrections become insignificant.

== Explosion ==
If a reactor is destroyed (by damage) while it is above 900℃, it will explode just like an [[atomic bomb]]. This explosion has enough power to destroy other reactors, so one explosion can lead to a chain reaction of exploding reactors. [https://clips.twitch.tv/KathishShakingPieBIRB]
