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,wherein at least one of the first and second containment layers comprises one or more shards of material each configured to sever the at least one signal path in the first sensor layer when the one or more shards are mechanically disturbed.

Abstract
A system for detecting and containing a breach in a container. The container wall includes containment layers and a sensor layer sandwiched between the containment layers. The sensor layer contains a signal path that can be carried by a signal cable such as fiber optic or wire cable. The containment layers contain shards of material. When the wall of the container is compromised, the signal in the sensor layer is altered by the disturbed shards cutting the signal cable, thus allowing for the detection of a rupture, vandalism or an unauthorized access attempt, The containment layers may be composed of a gel or rubber material to slow leakage.

21. A security system comprising:
-
a first containment layer comprising a first material; a first sensor layer having at least one signal path disposed therein and extending across substantially an entire area of the first sensor layer, the at least one signal path having a first end and a second end and the at least one signal path comprising at least one of an optical fiber and a wire; a second containment layer comprising a second material and arranged such that the first sensor layer is between the first and second containment layers; and at least one detector coupled to the at least one signal path and configured to detect a signal in the signal path from the first end to the second end and, when a signal is detected that is less than a predetermined threshold level, configured to provide a first output signal, wherein at least one of the first and second containment layers comprises a shard of material configured to sever the at least one signal path in the first sensor layer when the shard of material is mechanically disturbed. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)
