Which risk increases during subcritical nuclear reactor operation?

💡 Explanation

Accumulation of fission product poisons increases because the fissile material undergoing nuclear fission generates elements that strongly absorb neutrons; therefore reactor reactivity is suppressed, rather than increased heat causing cladding stress, since criticality is avoided.

• Which consequence results when an uncooled two-stroke engine exceeds optimal throttle during operation?
• Which phenomenon arises where inertial force balances gravity?
• Which risk increases when a planar capacitor's dielectric degrades?
• Which outcome increases when a supercritical fluid exceeds a Reynolds number threshold?
