After completing the main quest, Dana Feyton at Club Fusion will give you a side quest called "Things Go Better with Nuka Cola".

Dana is sick of Raiders stealing the Nuka Cola shipments to Club Fusion, so she gives the player a quest to find the machine schematics and recipes so that Club Fusion can start making its own Nuka Cola in-house.

The quest takes you all over the Commonwealth to find the schematics and recipes, which are located on 9 different terminals, each guarded by various enemies.  These are all vanilla terminals.  If another mod alters those same terminals, and that mod is lower in load order than Fusion City Rising, you may not find the recipe on the terminal as intended.

For example, the mod Raider Children edits the same terminal at the Beantown Brewery (Tower Tom's Terminal).  You can try placing Fusion City Rising lower in your load order than Raider Children to fix this, or if you prefer not to, you'll need to cheat via console command to advance the quest.  Here are the quest stages:

How to advance the quest via console command

Step 1: Console command: help NukaStationQuest 0.  This will return the Quest ID.

Step 2: Console command: setstage <QuestID> <Stage NUM>. Sets a current quest to a specific stage, completing all objectives before it. Use this command to complete bugged objectives.

Step 3: Now add the item that you were supposed to find in a given stage, e.g. Nuka Overdrive.  Console command: help "overdrive" 4.  Find the 8 digit code for Nuka Overdrive from the list that pops up.  Then console command: player.additem xxxxxxxx to add the Nuka Overdrive holotape to your inventory.  Replace xxxxxxxx with the 8 digit code from the list on the console.
