Nuclear Salt Water Rocket: Balancing Supercritical Explosions

Quick Summary

• The Nuclear salt Water Rocket (NSWR) faces criticism for physical constraints like neutron moderation in hydrogenous mixtures,which prevent a fast-spectrum detonation.
• Thermal neutrons in a mixture like uranium bromide in water lead to self-limiting reactions, unlike the fast-neutron reactions required for high energy yields.
• Alternative formulations, such as using fluorine or uranium hexafluoride, also face challenges due to neutron moderation properties.
• Potential solutions include using low-moderating solvents or carriers, increasing fissile concentration, utilizing magnetic confinement, and employing fast-neutron reflectors.
• Modifications aim to achieve better efficiency than traditional NTP but remain complex with practical challenges.
