Embodiment 1

[0019] Such as figure 1 As shown, this embodiment is an external neutron source-driven nuclear battery, including a heat source and a thermoelectric conversion device 5 arranged outside the heat source. The heat source includes a neutron source module 1 placed at the center of the heat source, wrapped in a neutron The fuel core 2 on the outside of the source module 1 axially, the beryllium reflective layer wrapped on the axially outside of the fuel inner core 2 forms the fuel container 3 , and the graphite reflective layer module 4 wrapped on the outside of the fuel container 3 is composed of graphite.

[0020] Preferably, the material of the neutron source module 1 is 252 Cf.

[0021] Preferably, the material of the fuel core 2 is a fissile nuclide, such as 235 Metal U fuel with 100% U enrichment.

[0022] Preferably, the radius of the neutron source module 1 is 0.435cm; the inner radius of the fuel core 2 is 0.435cm, and the outer radius is 1.38cm; the inner radius of the...

Embodiment 2

[0024] Such as figure 2 As shown, this embodiment is an external neutron source driven nuclear battery. Compared with Embodiment 1, only a metal layer 6 is wrapped outside the graphite reflective layer module 4, and the material of the metal layer 6 is copper, aluminum or cadmium. By wrapping a layer of metal layer 6 outside the graphite reflection layer module 4, the strength of the external neutron source driven nuclear battery of the present invention can be increased.

[0025] Preferably, the radius of the neutron source module 1 is 0.435cm; the inner radius of the fuel core 2 is 0.435cm, and the outer radius is 1.38cm; the inner radius of the fuel container 3 formed by the beryllium reflective layer is 1.38cm , the outer radius is 2.18cm; the length, width and height of the graphite reflective layer module 4 are respectively 4.86cm, 4.66cm and 5.31cm; the length, width and height of the metal layer 6 are respectively 5.41cm, 5.21cm and 5.86cm.

Abstract

The invention discloses an external neutron source drive type nuclear battery which comprises a heat source and a thermoelectric conversion device arranged outside the heat source. The heat source comprises a neutron source module, a fuel kernel, a fuel container and a graphite reflector module, wherein the neutron source module is arranged at the center of the heat source; the fuel kernel is enwrapped outside the axial direction of the neutron source module; the fuel container is enwrapped outside the axial direction of the fuel kernel and formed by a beryllium reflector; and the graphite reflector module enwrapped outside the fuel container and formed by graphite. The neutron source module is made of 252Cf; and the fuel kernel is made of fissile nuclide. The external neutron source drive type nuclear battery has the advantage that while the advantage of modularization of a radioactive isotope nuclear battery is kept, the specific power and the thermal power output of the nuclear battery are further improved.
