Nuclear

For the nuclear industry

Hiden Mass spectrometers are used for a wide range of applications within the Nuclear Industry including bespoke configured gas analysers for leak detection of fuel rods, thermal hydraulic testing, rare earth gases, H.D,T and fusion fuel analysis.

A range of real time, single point, multi-stream and precision batch/discrete very low volume sample gas analysers are available.

Hiden TPD Workstation is used for the study of hydrogen and deuterium material in fusion reactor research.

In surface analysis, Hiden’s SIMS analysers provide high sensitivity surface composition analysis with depth resolution at the nanometre scale.

OVERVIEW

Precision analysis of low molecular weight gases is of critical importance for a range of scientific research studies, many are directly associated with the nuclear industry, fusion projects for example. Typical stringent applications include low abundance and impurity measurement, gas mixture quantification and precise isotope ratio measurement. The small swept volume of the HPR-70 batch gas analyser is a major asset for analysis of minimal gas samples in applications such as nuclear fuel rod leak detection for example.

Multi stream Analysis of the composition and characteristics of vent streams from ‘Heat Removal’ safety systems of reactor systems is key to the development of Passive Protection Systems (PPS). Hiden QIC MultiStream gas/vapour analysis systems have been used to investigate the function and reliability of passive condensers under severe accident conditions, in the presence of “non-condensable” gases N2 for example, which can markedly affect the efficiency of the PPS.

At nuclear fusion research facilities, special analysis of the vacuum conditions within Tokamaks is challenging due to complex interactions of hydrogen isotopes within the Tokamak. Typically, gas purity is assessed by using RGAs and obtaining conventional mass spectrum. Validation of fusion fuel purity is complicated due to D2 and 4He occupying the same atomic mass, 4 amu (mass separation 0.0254 amu), rendering fuel validation purity problematic using conventional mass spectrometry RGA techniques. Hiden’s qRGA systems provide a low cost solution.

Materials studies for reactor design require stringent testing of surface composition and of the key adsorption/desorption mechanism’s. Hiden’s sims secondary ion mass spectrometers provide for high sensitivity surface composition at the nanometre scale. Low background/High signal are features of Hiden’s TPD Workstation that provides for high sensitivity analysis of hydrogen and deuterium in steels.
