Millstone Unit 2 TS Required Shutdown Even with the emergency TS Friday, Millstone Unit 2 reached the TS required action level of 75 degrees for their UHS temperature limit Saturday night. Conditions improved and they exited the TS, only to re-enter it at 0830 Sunday. They reached Hot Standby at 1346 (required within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />) and have commenced actions to be in the required cold shutdown mode within 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />, expected Monday morning.

Jo Ambrosini reported to the site a number of times over the weekend to provide coverage. There is no indication of how long Unit 2 will remain down, or what work they may do during the shutdown. Even if conditions improve again, they have indicated they will continue on this path instead of cycling the organization.

There are no other unusual conditions or actions to report at this time. Unit 3 is not affected as they calculate their UHS temperature limit in a different manner due to. where the intake of water into the plant is located.

We will provide an update Monday morning, Ron 1.
