<p class="MsoNormal">During the outage, we have had a first time issues with accumulator valve testing (Accumulator dumps into the cavity when it is full of water) resulting in airborne conditions in upper containment.

<p class="MsoNormal">Does anyone else have this issue?<o:p></o:p></p>

<p class="MsoNormal">If so do you restrict access during accumulator dump activities in case of airborne conditions?<o:p></o:p></p>
