 Activity: Add an extra institution into the Region
 -------------------------------------------------
-Having multiple institutions help organize facilities and their affiliation.
-In our ``USA`` region, let's add a second institution called ``ReactorUtility``.
-``ReactorUtility`` is the institution that holds the ``1178MWe ReactorPlant Unit 1`` prototype and ``United 
-States Nuclear`` holds the ``UraniumMine``, ``EnrichmentPlant``, and ``NuclearRepository``
-prototypes. Using the region and institution templates, let's 
-add the second institution to the region.
