The InSITEtm Spectrographic system for in-situ analysis in nuclear
power plants and other difficult locations.
Reactor coolant pressure boundary leakage
in pressurized water reactors leaves a white boric acid buildup that is
corrosive to low alloy and carbon steel components. However, not every white
deposit found in a PWR is boric acid, and identification of unknown deposits can
be crucial in determining if an active leak exists. Current methods for
identifying the source of unidentified deposits require a sample to be removed
and analyzed using radiometric or chemical techniques. This approach is
time-consuming, requires potential radiation exposure to personnel, suffers from
false positives, and may not be possible in locations that are inaccessible or
where only small amounts of deposits exist. The InSITE uses a new technique based on
Raman spectroscopy that allows in-situ analysis and positive identification of
boric acid residue. This technique can also determine the state of hydration of
the boric acid, which will help understand the nature of the source of the
residue. The spectroscopic analyses of other common materials that may be
mistaken for boric acid can identified and eliminated. The technology
applications to nuclear power plants has recently been gaining popularity with
its ability to be applied in the field without extensive ladders or scaffolding,
lower dose, and 100 percent sample identification reliability.
Is it a leak?
- Simple operation and deployment for in-situ analysis
- Positive identification of the chemical content of difficult to sample
deposits--distingushes between primary and secondary coolant spills without
removing samples from containment
- Results in huge cost savings and shorter outages
