Description

FBR x10 Configurable

Find scaling FBR in mid-late game a hurdle? Tired of adjusting your FBR build every now and then? I have a solution for you. This module can provide you with plently of power/salt/chlorine/brine/water, and allow for easy shift of production based on your demand by switching modules, or pause/unpausing a few evaporation pond (heated)/electrolyzer.

List of bluprints include

#### function
base Base module containing fuel processing and FBRs
A Power module
B Hydrogen module
C1 Salt/chlorine module (breeder)
C2 Salt/chlorine module (breeder) + extra slat/chlorine production from input brine
D1 Hydrogen/power module (breeder)
D2 Hydrogen/power module (breeder) + extra slat/chlorine production from input brine

How to use

Follow the steps:

  1. Put down FBR x10 (Base)
  2. Pair power reactor with module A/B
  3. Pair breeder reactor with module C1/C2/D1/D2
  4. Pre-load fuel pipes with fuel (check start up section)
  5. Connect sea water bus and output product bus
  6. Fill the input storage untill there's no warnings
  7. Pause building for differen power level using table from Running different FBR multiplying levels section

Beware of the max limit of the bus:

I/O item pipes max throughput
in sea water 8 7200
out hydrogen 4 3600
out oxygen 4 3600
out water 4 3600
out brine 4 3600

Make sure you've got the nuber calculated. Some of the brine and salt are fed back to produce new fuel.

Caution

You need a total of 9 radioactive waste storages to run at full capacity (6 reprocessing maxed out). This build only fits 4 in, so you need to add 5 more by yourself.

Please check the recommanded configs, and try too keep the brine balance positive by pausing a few evaperation pond (heated) or electrolyzer II. Usually there will be enough brine overflow to be used.

A fluid storage named "FBR brine" recieve produced brine from the plant for toxic slury treatment, it will warn you when you don't have enough brine overflow.

Start up requirements

To start up the reactor, you need to preload it with core fuel and balnket fuel from the main fuel bus. You also need to provide resources to start the system via input storages.

  • height 0: molten glass output (for nuclear reprocessing plant)
  • height 1: core fuel input
  • height 3: blanket fuel input
  • Water starter (fluid storage): initiating acid production
  • Input resource storages: for self sustained fuel production

All storages are set with proper warnings, so if there's any warning from this build, you're not ready to start the system.

I highly recommand you save up 1000 Plutonium and a big pile of spent MOX/spent fuel. This makes pre-loading of fuel pipe with core/blanket fuel easy, as you only need a chem plant (plutonium -> core fuel) and a nulcear reprocessing plant (spent MOX/spent fuel -> blanket fule).

Running different FBR multiplying levels

When you first put down this bluprint, you likely don't need everything running at max. Here are the numbers of different facilities you need to run the system at different breeder levels (sum).

Breeder lv Power x4 FBR Mixer II (acid) Waste water treatment Chem plants Crusher (large) Nuclear reprocessing plant Settling tank Enrichment plant Radioactive waste storage
1 1 1 1 1 1 1 2 2 2
2 2 1 1 2 2 2 3 3 3
3 3 1 2 3 3 3 5 5 4
4 4 1 2 3 3 3 6 6 5
5 5 2 3 4 4 4 8 8 6
6 6 2 3 5 5 5 9 9 7
7 7 2 4 6 6 6 11 11 8
8 8 2 4 6 6 6 12 12 9

Mixer I and crusher are for reprocessing and filter media production, they cannot and should not be paused. As stated previously, you will need to add extra 5 Radioactive waste storages.

Notes

Switching between modules

You can use the "deconstruction mode" in bluprint selection window to switch between modules easily. This is also the recommanded way to do deconstruct a module safely.
