Abstract

A nuclear reactor is constructed in sub-modules and super modules which are manufactured, packaged, and shipped to a construction site. At least some of the modules are packaged in suitable shielding containers or portions of containers, which may be steel. The modules are assembled on-site, and some of the modules remain within their respective shipping containers after assembly. One or more of the shipping containers may be used as concrete forms to support the pouring of concrete in between selected modules. The concrete may be used for structural support, shielding, or both.

First claim

What is claimed is:

1. A method of constructing a nuclear reactor, comprising:
fabricating one or more sub-modules in a manufacturing facility, the one or more sub-modules comprising a skid and a shielding;
assembling one or more sub-modules into one or more super modules using temporary connections at the manufacturing facility;
disassembling the super modules;
transporting the sub-modules to an installation site;
assembling, at the installation site, two or more of the one or more sub-modules using permanent connections;
installing concrete form ties between the two or more sub-modules;
welding the two or more sub-modules together to create a super module;
pouring concrete between the two or more sub-modules; and
installing the super module in place.

2. The method of claim 1 , wherein the one or more sub-modules include one or more of a compressor module, a tank module, and a charcoal bed module.

3. The method of claim 1 , wherein the shielding is made up of multiple pieces and further comprising the step of, at the installation site: welding the multiple pieces of shielding to the sub-module.

4. The method of claim 1 , wherein transporting the sub-modules to the installation site comprises shipping the sub-modules by truck.

5. The method of claim 1 , wherein a first submodule of the one or more submodules has a steel container permanently formed around the first submodule, the steel container having a preformed aperture.

6. The method of claim 5 , wherein the first submodule comprises a pipe coupled to the preformed aperture.

7. The method of claim 1 , wherein the step of pouring concrete between the two or more sub-modules is performed after the step of installing the super module in place.

8. A method of constructing a nuclear reactor, comprising:
fabricating one or more sub-modules in a manufacturing facility, the one or more sub-modules comprising a skid and a shielding;
assembling one or more sub-modules into one or more super modules using temporary connections at the manufacturing facility;
disassembling the super modules; and
transporting the sub-modules to an installation site;
wherein the shielding is made up of multiple pieces and further comprising the step of, at the installation site: welding the multiple pieces of shielding to the sub-module.

9. The method of claim 8 , further comprising assembling, at the installation site, two or more of the one or more sub-modules using permanent connections;
installing concrete form ties between the two or more sub-modules;
welding the two or more sub-modules together to create a super module;
installing the super module in place; and
pouring concrete between the two or more sub-modules.

10. The method of claim 8 , wherein the one or more sub-modules include one or more of a compressor module, a tank module, and a charcoal bed module.

11. The method of claim 8 , wherein a first submodule of the one or more submodules has a steel container permanently formed around the first submodule, the steel container having a preformed aperture.

12. The method of claim 11 , wherein the first submodule comprises a pipe coupled to the preformed aperture.
