Inherently safe passive gas monitoring system
First Claim
1. A passive gas monitoring system, the system comprising:
- an inductive power receiver positioned within a nuclear material storage container, wherein the inductive power receiver is configured to receive power from an inductive power transmitter positioned outside the nuclear material storage container using inductive power transfer;
one or more sensors positioned within the nuclear material storage container, wherein the one or more sensors are configured to respectively provide one or more outputs respectively describing one or more conditions within the nuclear material storage container, wherein the one or more sensors receive power from the inductive power receiver, and wherein the one or more sensors comprise;
a first sensor for measuring hydrogen concentration; and
a second sensor for measuring oxygen concentration; and
at least one data transmitter positioned within the nuclear material storage container, wherein the at least one data transmitter is configured to transmit the one or more outputs respectively provided by the one or more sensors to a data receiver positioned outside the nuclear material storage container.

Abstract
Generally, the present disclosure is directed to gas monitoring systems that use inductive power transfer to safely power an electrically passive device included within a nuclear material storage container. In particular, the electrically passive device can include an inductive power receiver for receiving inductive power transfer through a wall of the nuclear material storage container. The power received by the inductive power receiver can be used to power one or more sensors included in the device. Thus, the device is not required to include active power generation components such as, for example, a battery, that increase the risk of a spark igniting flammable gases within the container.
