NUCLEAR LEAKAGE DETECTION SYSTEM USING WIRE OR OPTICAL FIBER
First Claim
1. A detection and containment system for detecting and containing a breach in a container, comprising:
- a first containment layer;
a first sensor layer coupled to the first containment layer and having at least one signal path extending across substantially an entire area of the first sensor layer; and
a second containment layer coupled to the first sensor layer such that the first sensor layer is between the first and second containment layers;
wherein a failure of the at least one signal path to conduct a signal greater than or equal to a predetermined threshold level from a first end to a second end signifies a breach or an attempted breach of the container.

Abstract
A detection and containment system for detecting and containing a breach in a container includes a first containment layer and a first sensor layer coupled to the first containment layer. The first sensor layer includes at least one signal path extending across substantially an entire area of the first sensor layer. The first sensor layer may be provided by either a fiber optic carrying a light signal or a wire carrying an electrical signal. A second containment layer is coupled to the first sensor layer such that the first sensor layer is between the first and second containment layers. 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 such as a barrel, pipeline or the like, subsequent to a breach either from within, as in the case of a rupture, or from without, as in the case of vandalism or an unauthorized access attempt. The containment layers may comprise a gel or rubber material. An additional layer or layers may be provided to further protect against intrusion and may be made from material such as Kevlar. The signal layer detects a breach of a container while the other layers delay access to the contents. The increased time due to the delaying characteristics of the other layers increases the chances that the party attempting the unauthorized entry can be intercepted by the proper authorities. The detection and containment system may be implemented to protect tunnels, pipelines, hatches and manhole covers.
