NUCLEAR LEAKAGE DETECTION SYSTEM USING WIRE OR OPTICAL FIBER
First Claim
1. A system for detecting a status of a container, comprising:
- a first containment layer coupled to a surface of the container and comprising a first sensor having a first signal path extending across substantially an entire area of the first containment layer; and
a second containment layer coupled to the first containment layer and comprising a second sensor having a second signal path extending across substantially an entire area of the second containment layer,wherein a failure of either the first or second signal path to conduct a respective signal greater than or equal to a predetermined threshold level from a respective first end to a respective second end signifies a breach in the respective containment layer,the system further comprising;
a controller coupled to the first and second signal paths and configured to characterize the status of the container as a function of one or more of;
which of the first and second signal paths has failed;
if both signal paths have failed, which signal path failed first; and
if both signal paths have failed, a time period between the failures.

Abstract
A system for detecting and containing a breach in a container includes a first containment layer and a first sensor layer. The first sensor layer includes at least one signal path extending the first sensor layer. The first sensor layer may be provided by either a fiber optic or a wire. An inability of the at least one signal path to conduct a signal from a first end to a second end represents either a breach, or an attempted breach, from outside the container or a failure of the container. The containment layers may seal against any leakage of material in a container subsequent to a breach either from within or from without. An additional layer may be provided to protect against intrusion and may be made from material such as Kevlar. The detection and containment system may be implemented to protect tunnels, pipelines, hatches and manhole covers.

28. A system for detecting a status of a container, comprising:
-
a first containment layer coupled to a surface of the container and comprising first and second signal paths extending across substantially an entire area of the first containment layer, wherein each of the first and second signal paths is disposed in a first and second plane, respectively, the first plane being positioned between the surface of the container and the second plane, and wherein a failure of either the first or second signal path to conduct a respective signal greater than or equal to a predetermined threshold level from a respective first end to a respective second end signifies a breach in the first containment layer, the system further comprising; a controller coupled to the first and second signal paths and configured to characterize the status of the container as a function of one or more of; which of the first and second signal paths has failed; if both signal paths have failed, which signal path failed first; and if both signal paths have failed, a time period between the failures.
