Description

The company that brought you the Nuclear Reactor! Check it out in our games! If you join this group, you will be auto-assigned a role in the reactor. Post on the group wall and let us known what role you'd like to automatically have! The following are the available roles: Civilian -Absolutely no responsibilities! Material Handler -Mines for ore and isotopes and turns them into fuel. Waste Specialist -Stores nuclear waste and recycles it into fuel. Security Guard -Imprisons mutants and criminals, and has an armory to do so. Safety Officer -Stores isotopes and handles radioactive shielding. Reactor Operator -Runs and upgrades the reactor. Plant Manager -Controls reactor funds and worker salaries. Nuclear Engineer -Can do it all, but requires the Nuclear Engineer license. All other roles are management roles that have extra powers and responsibilties within this group, or suspension roles for members who necessitate it.

Membership history

Growth

2 measurements spanning 41 days, net +1. 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 28–29 and does not start at zero.
