Rasvyat Nuclear Power Station is a physics-based nuclear reactor simulation where players operate and maintain a functioning power plant. Using realistic calculations, players must keep the reactor stable while responding to various emergencies including system failures and power outages. Every operator decision has long-term consequences, with mistakes potentially leading to reactor trips, equipment damage, or catastrophic meltdowns.
