NUCLEAR SALT-WATER ROCKET

A 'nuclear salt-water rocket' is a type of nuclear thermal rocket designed by Robert Zubrin that would be fueled by water bearing dissolved salts of plutonium or U²³⁵. These would be stored in tanks that would prevent a critical mass from forming by some combination of geometry or neutron absorption. The rocket would be powered by a nuclear-thermal reaction when the water was injected into a reaction chamber.
Calculations show that this rocket would have both very high thrust (1.3 × 10⁷ N, for one design) and a very high specific impulse (66 kN·s/kg for the same design), a rare combination of traits in the rocket world.
The vessel's exhaust would contain radioactive isotopes, but these would be rapidly dispersed after traveling only a short distance; the exhaust would also be traveling at high speed (in Zubrin's scenario, faster than Solar escape velocity, allowing it to eventually leave the Solar System).
