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

Welcome to Neutron Inc Reactor Core (NIRC). Operate the nuclear reactor to generate power, do maintenance tasks, explore the deep underground facility and more. If the core becomes too unstable it can reach a point of no return and enter in meltdown, you can still shutdown it if you manage to lower the reactor temperature low enough.

Growth history is still building. We hold one measurement for this entry. A trend needs at least two, taken days apart — so this will fill in on its own rather than being estimated. We do not publish numbers we have not measured.

Growth

2 measurements spanning 10 days. 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 82–84 and does not start at zero.
