a third layer disposed atop the second layer, the third layer comprising Chromium; and
wherein the interfacing material of the second layer is configured to suppress a chemical interaction between the base layer and the third layer.
2. The covering as claimed in claim 1 , wherein the first layer comprises at least one of Silicon Carbide or Carbon fiber.
3. The covering as claimed in claim 1 , wherein the first layer covers from about 40% to about 70% of the area of the outer surface of the base layer of the nuclear fuel cladding.
4. The covering as claimed in claim 1 , wherein the first portion of the base layer of the nuclear fuel cladding is a helical portion of the outer surface of the base layer.
5. The covering as claimed in claim 1 , wherein the first layer is configured as a fiber tape.
6. The covering as claimed in claim 5 , wherein the fiber tape has a width in the range of about 1 millimeter to about 5 millimeters.
7. The covering as claimed in claim 1 , wherein the interfacing material has a melting point greater than a beyond design basis accident temperature.
8. The covering as claimed in claim 7 , wherein the second layer comprises Molybdenum, Niobium, Tantalum, or Tungsten.
9. The covering as claimed in claim 1 , wherein the third layer comprises a Chromium-based alloy.
10. The covering as claimed in claim 9 , wherein the Chromium-based alloy comprises Yttrium or Molybdenum.
11. The covering as claimed in claim 9 , wherein the Chromium-based alloy comprises Iron, Aluminum, or a combination thereof.
12. The covering as claimed in claim 1 , wherein the third layer comprises a Chromium-based ceramic material comprising Nitrogen, Niobium, or a combination thereof.
13. The covering as claimed in claim 1 , wherein the covering comprises a fourth layer configured to surround the third layer, wherein the fourth layer is comprised of a Chromium-based alloy or a Chromium-based ceramic material.
14. A covering for reinforcing a cladding tube of a nuclear reactor, the covering comprising:
a first layer helically disposed atop the cladding tube, the first layer comprising a fiber-based material, wherein the first layer directly covers a first helical portion of an outer surface of the cladding tube and wherein a second helical portion of the outer surface of the cladding tube remains uncovered by the first layer;
a second layer disposed atop the first layer and in direct contact with the second portion of the cladding tube, the second layer comprising an interfacing material, wherein the second layer is directly attached to the second helical portion of the cladding tube and to the first layer to fasten the first layer to the cladding tube; and
a third layer disposed atop the second layer, the third layer comprising Chromium, wherein the interfacing material of the second layer is configured to suppress a chemical interaction between the cladding tube and the third layer.
15. The covering as claimed in claim 14 , wherein the second layer covers the first layer and the second helical portion of the cladding tube without any interruptions in the second layer.
16. The covering as claimed in claim 14 , wherein the first layer comprises at least one of Silicon Carbide or Carbon fiber.
17. The covering as claimed in claim 14 , wherein the first layer directly covers from about 40% to about 70% of the area of the outer surface of the cladding tube of the nuclear fuel rod.
