MP: The SEP0103 load will be out tomorrow morning, with a review later in the day. S/C: An LAE dome temperature sensor reading has been giving readings out of limits: 264 degrees, 2000 degrees recently. It's probably failing. This is not a concern, because it's no longer needed. Several of these sensors have failed, but none for a couple of years. We will examine the failure profile tos see how it compares with the previous ones. The first ASVT training session will be held in the Action Room at 1:00 today. See the OCC website for the complete schedule.
