Patent ID: 8718218

Claim:
A system for detecting at least one quality and/or quantity of at least one off-gas from a solution-based nuclear reactor, the system comprising: at least one gas management system; and at least one quadrupole mass spectrometer, wherein the at least one quadrupole mass spectrometer is located within the at least one gas management system, wherein the at least one quadrupole mass spectrometer determines one or more of the following qualities and/or quantities of a solution-based nuclear reactor: (i) the rate of production of at least one gas and/or gas species from the solution-based nuclear reactor; (ii) the effect on pH by one or more nitrogen species; (iii) the rate of production of one or more fission gases; and/or (iv) the effect on pH by at least one gas and/or gas species other than one or more nitrogen species from a nuclear reactor.
