The Nuclear Option is a quest and Fallout 4 achievements and trophies in Fallout 4.

Bugs

 * Teleporting into the Institute wearing the a power armor helmet with the Targeting HUD mod (or any other item with the Targeting HUD attached due to a mod) with this quest active makes the player partially hostile to the Institute, denying the player access to the elevator and not spawning any institute NPCs except Father. Reloading a save from before entering the institute for the final time and taking off the Targeting HUD mod is recommended, though the quest may be completable with copious abuse of tcl.
 * If the quest is never started (for example, if decided to destroy the Railroad instead), the rebel synths on the mining floor will still be there, non-hostile, standing and doing nothing forever.
 * After detonating, some players might experience the screen fading to black and eventually will be stuck loading the next cutscene. You use the console to relocate yourself to another location with the command (in this case, Red Rocket) and continue the game. Then type  to update the Mass Fusion building cell.
 * If you dismiss a companion while in the Institute, they never return home. Tested on PC by dismissing Deacon in favor of X6-88 while in the SRB wing. After, player.moveto finds him standing there in SRB.
