<p class="MsoNormal">Am hoping to get some surveys of the SG secondary side while the SG is drained. This outage we are doing some guide vane repairs on top of the SG inside on the 1<sup>st</sup>, 2<sup>nd</sup>, and 3<sup>rd</sup> platforms. We have surveys
with the secondary side water level over the tubes, but none when drained. Being challenged based on the schedule to possibly work while drained. Appreciate your time/help.........Thx Joe
