resumed recording at belor the alarm point.
No technician was ever called to check the alarm, recorde, or radiation sensor.
No lab technician ever analyzed the off-gas (due tb this alarm).

Indicationu to me was what we had studied as a " Crud Burst" where tramp uranium somewhere on the outside of the fuel is vaporized and removed in the
~
l off-sas system.
I infor:ed the shift and General Elcctric supervisors of

l
=y sucpicions.
Since the off-Saces were delayed some 30 minutes (at that time) before atmospheric rel' ease, the next sympton o f a " Crud Burst" would l
have been high activity in the stack Eas.
This did occur and was recorded on strip chart recorders and the recordings sent to management the following l
day.
As fcr as I know, this incident wcs n~e'ver reported to mana5ezent, and mana6ement either did not kdow enough about the charts to read them acdurgtely Although 'h.'
cas a reportable incident accordinc f or didn' t ever look at them.
