Appropriation

Appropriation is an Institute radiant quest in Fallout 4.

Detailed walkthrough
Speak with Evan Watson of the Institute's Advanced Systems section. He'll tell the Sole Survivor he is impressed with the Brotherhood of Steel's technology and that the Institute could learn a lot from it. He will then proceed ask the player character to go to the surface and find some blueprints for him, advising that there is a small Brotherhood salvage team that has some of these blueprints, thus being the target for collection of blueprints.

Upon arrival at the location, a small team of Brotherhood members will be guarding the blueprints, who will become hostile when attempting to retrieve the blueprints. Kill them, take the blueprints and return to the Institute. When handing them to Watson, he can be convinced with a speech check to give a reward, which if successful, will be 4 fusion cells.
