Section: claims

1. A system, comprising:a nuclear reactor chamber comprising an inlet portion;wherein the chamber is part of a nuclear power plant,at least one container,wherein each respective container of the at least one container contains liquid nitrogen and boron powder,wherein each respective container comprises an outlet portion in fluid communication with said inlet portion; andat least one valve associated with the at least one container,wherein each respective container is associated with a respective valve of the at least one valve,wherein opening of the at least one valve causes both liquid nitrogen and boron powder to flow from at least one respective container of the at least one container into the chamber. 2. The system of claim 1 wherein a first container has a first volume; and the system further comprising a second container containing liquid nitrogen, the second container having a second volume greater than the first volume, the second container in fluid communication with the at least one container. 3. The system of claim 2, further comprising an apparatus configured to produce liquid nitrogen, the apparatus configured to produce liquid nitrogen is in fluid communication with the first container. 4. The system of claim 2, wherein the boron powder is added into the first container, the boron powder is ejected into the nuclear reactor chamber along with the flow of liquid nitrogen from the first container to the nuclear reactor chamber.
