Which risk increases in a nuclear reactor nearing criticality?

💡 Explanation

As criticality approaches, the rate of nuclear fission accelerates, therefore neutron flux increases exponentially because the chain reaction amplifies neutron production, rather than effects coolant boiling or fuel rod stress which would not be immediate.
