Abstract

Illustrative embodiments provide systems, applications, apparatuses, and methods related to nuclear fission deflagration wave reactor cooling. Illustrative embodiments and aspects include, without limitation, nuclear fission deflagration wave reactors, methods of transferring heat of a nuclear fission deflagration wave reactor, methods of transferring heat from a nuclear fission deflagration wave reactor, methods of transferring heat within a nuclear fission deflagration wave reactor, and the like.

Claims (26)

1. A method of transferring heat of a nuclear fission deflagration wave reactor, the method comprising:

disposing nuclear fission fuel material in at least a portion of at least one primary heat pipe;

propagating a nuclear fission deflagration wave in the nuclear fission fuel material in a reactor core assembly of a nuclear fission deflagration wave reactor; and

during propagating the nuclear fission deflagration wave, transferring heat from the propagating nuclear fission deflagration wave to the at least one primary heat pipe.

2. The method of claim 1 , further comprising:

transferring heat from the at least one primary heat pipe to at least one secondary heat pipe that is external of a reactor vessel; and

transferring heat from the at least one secondary heat pipe to at least one external heat sink that is external of the reactor vessel.

3. The method of claim 1 , further comprising:

transferring heat from the nuclear fission fuel material to at least one internal heat pipe that is disposed internal to a reactor vessel; and

transferring heat from the at least one internal heat pipe to at least one internal heat sink that is disposed internal to the reactor vessel.

4. The method of claim 1 , wherein heat is transferred from a portion of the nuclear fission fuel material proximate a burnfront of the nuclear fission deflagration wave.

5. A method of transferring heat from a nuclear fission deflagration wave reactor, the method comprising:

disposing nuclear fission fuel material in at least a portion of at least one primary heat pipe;

propagating a nuclear fission deflagration wave in the nuclear fission fuel material in a reactor core assembly of a nuclear fission deflagration wave reactor;

during propagating the nuclear fission deflagration wave, transferring heat from the propagating nuclear fission deflagration wave to the at least one primary heat pipe; and

transferring heat from the at least one primary heat pipe to at least one external heat sink that is external of a reactor vessel.

6. The method of claim 5 , further comprising:

transferring heat from the at least one primary heat pipe to at least one secondary heat pipe that is external of a reactor vessel; and

transferring heat from the at least one secondary heat pipe to at least one external heat sink that is external of the reactor vessel.

7. The method of claim 5 , further comprising:

transferring heat from the nuclear fission fuel material to at least one internal heat pipe that is disposed internal to a reactor vessel; and

transferring heat from the at least one internal heat pipe to at least one internal heat sink that is disposed internal to the reactor vessel.

8. The method of claim 5 , wherein heat is transferred from a portion of the nuclear fission fuel material proximate a burnfront of the nuclear fission deflagration wave.

9. The method of claim 1 , further comprising disposing the at least one primary heat pipe in the reactor vessel.

10. The method of claim 1 , further comprising disposing a second at least one primary heat pipe in the reactor vessel and external to the nuclear fission fuel material, and wherein transferring heat from the propagating nuclear fission deflagration wave to the at least one primary heat pipe includes transferring heat from the propagating nuclear fission deflagration wave to the second at least one primary heat pipe.

11. The method of claim 1 , further comprising disposing a second at least one primary heat pipe substantially orthogonal to a fuel assembly containing at least a portion of the nuclear fission fuel, and wherein transferring heat from the propagating nuclear fission deflagration wave to the at least one primary heat pipe includes transferring heat from the propagating nuclear fission deflagration wave to the second at least one primary heat pipe.
