Claims (19)

1. A modular nuclear fission deflagration wave reactor comprising:

a plurality of neutronically couplable nuclear fission deflagration wave reactor modules; and

a plurality of nuclear shielding material receivers configured to removably receive nuclear shielding material such that each neutronically couplable nuclear fission deflagration wave reactor module is configured to be neutronically shielded from at least one adjacent neutronically couplable nuclear fission deflagration wave reactor module.

2. The modular nuclear fission deflagration wave reactor of claim 1 , further comprising nuclear shielding material that is removably received in at least one of the plurality of nuclear shielding material receivers.

3. The modular nuclear fission deflagration wave reactor of claim 2 , wherein the nuclear shielding material is configured to attenuate at least one radiation type chosen from neutron radiation and Υ radiation.

4. The modular nuclear fission deflagration wave reactor of claim 3 , wherein the nuclear shielding material includes neutron moderating material configured to slow down a neutron spectrum.

5. The modular nuclear fission deflagration wave reactor of claim 4 , wherein the neutron moderating material includes low-A material.

6. The modular nuclear fission deflagration wave reactor of claim 5 , wherein the low-A material includes at least one element chosen from carbon, boron, lithium, and berylium.

7. The modular nuclear fission deflagration wave reactor of claim 3 , wherein the nuclear shielding material includes neutron absorbing material.

8. The modular nuclear fission deflagration wave reactor of claim 7 , wherein the neutron absorbing material includes at least one element chosen from lithium and europium.

9. The modular nuclear fission deflagration wave reactor of claim 3 , wherein the nuclear shielding material includes Υ absorbing material.

10. The modular nuclear fission deflagration wave reactor of claim 9 , wherein the Υ absorbing material includes high-Z material.

11. The modular nuclear fission deflagration wave reactor of claim 10 , wherein the high-Z material includes at least one element chosen from tungsten, tantalum, lead, rhenium, gold, platinum, and hafnium.

12. The modular nuclear fission deflagration wave reactor of claim 2 , wherein at least one of the plurality of nuclear shielding material receivers are disposed proximate at least one of the plurality of neutronically couplable nuclear fission deflagration wave reactor modules.

13. The modular nuclear fission deflagration wave reactor of claim 12 , wherein the at least one of the plurality of nuclear shielding material receivers are disposed on an exterior surface of the at least one of the plurality of neutronically couplable nuclear fission deflagration wave reactor modules.

14. The modular nuclear fission deflagration wave reactor of claim 12 , wherein the at least one of the plurality of nuclear shielding material receivers are disposed intermediate adjacent neutronically couplable nuclear fission deflagration wave reactor modules.

15. The modular nuclear fission deflagration wave reactor of claim 2 , wherein the removable nuclear shielding material is removably receivable within a portion of the at least one neutronically shielded nuclear fission deflagration wave reactor module.

16. The modular nuclear fission deflagration wave reactor of claim 15 , wherein the removable nuclear shielding material is removably receivable within an exterior wall of the at least one neutronically shielded nuclear fission deflagration wave reactor module.

17. The modular nuclear fission deflagration wave reactor of claim 15 , wherein the nuclear shielding material receiver includes a port configured to receive a fluid.
