Test for Reactor Vessel Damage Assessment

Posted January 20, 2017 12:00 AM by Engineering360 eNewsletter

An analytical method pioneered by MIT researchers could change the way operators measure damage to nuclear reactor vessels. This method could potentially provide continuous monitoring and prevent unnecessary replacement of materials. The testing method uses acoustic vibrations to gauge material damage levels.

This article seems confused.

The lead suggests continuous in situ monitoring of the reactor pressure vessel degradation via radiation (and probably corrosion). It goes on to claim TEM is the current method of assessing such damage.

AFAIK, TEM does not allow in situ testing of a functioning reactor. It would require destructively obtaining a sample. Sure you can irradiated samples and test, but that isn't what the article is describing..... which leaves me wondering about the conditions for the test in question.

The article goes on to describe testing on aluminum and copper...not common reactor pressure vessel materials.

At the very end a shift is made to cladding....which is not found on the reactor pressure vessel and other than relative proximity, doesn't have a lot to do with the pressure vessel.

I believe the article is in sighting testing method change on different material for a bases to assign to nuclear arena. examples of testing on copper and aluminum.

I believe they are trying to sell this method for assessing damage, into a belief that destructive testing can be eliminated through acoustic waves. and the timing of assessment will be immediate.

( Its a sales pitch for funding ) but if it works great !
