Description (written by the developer; not a statement by this register)

-- [ REALISTIC BOILING WATER REACTOR ] -- [ V2.1.0 - Public Release. ] -- Hello employee, and welcome to the Harrison Generating Station, located in Abbotsford, Canada! This reactor simulation experience aims to deliver the most engaging 3D multiplayer reactor simulator ever made! We aim to provide players with a realistic experience operating a Boiling Water Nuclear Reactor while keeping the game arcade-style so players can have fun. In Realistic Boiling Water Reactor Simulator, you earn points for successfully meeting electricity demand from the grid. The more points you earn, the higher your facility rank is, allowing you to unlock more rooms, abilities, and much more! Please utilize the in-game tutorials before starting, so you know how to operate the reactor! RBWR features three selectable classical BWR reactor types, plus an RBMK reactor type across two playable units. Unit 01 is simplified for learning, while Unit 02 offers more advanced and in-depth realistic operations.

11 measurements spanning 12 days, net -111. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 75–220 and does not start at zero.
