RE: Millstone UHS Current Status (8/16/12)
Thanks Jim.
We've heard they are leaning towards Unit 2 restart option #2, with the earliest projected startup date being Tuesday, August 21. No formal decision has been made to restart at this time, From: Kim, James Sent: Thursday, August 16, 2012 1:31 PM To: Ambrosini, Josephine; Krafty, James; Setzer, Thomas; Bellamy, Ronald

Millstone UHS Current Status (8/16/12)
Based on a phone call with the Millstone, licensing manager, Bill Bartron on 8/16/12:
Current Status of UHS Water Temperature:
Unit 2 - 73.25TF Unit 3-71.7°F Restart of Unit.2 Options:
- 1) Conservative Approach - Restart on or after 9/10/12 based on historical weather data and projections.
- 2) Less Conservative but high reliability - Restart if the 24-Hr avg. temperature is at or below 73TF for 3 consecutive days with 10 days projection of no significant UHS temperature increase.
If the UHS temperature gets near the TS limit, then the following path forward is proposed:
Unit 3: 1) NOED
- 2) One-Time Emergency Amendment to increase the temperature limit from 75 0F to 770F for a period of 4-8 weeks.
In discussion between Millstone and ISO New England, there would be a significant impact on the grid stability and electricity demand if both Units 2 and 3 were to shutdown. And this event may meet the NOED criteria.
Unit 2: Exigent Amendment to increase the temperature limit from 75 0F to 770F for a period of 4-8 weeks. Unit 2 is currently in Mode 5 and the emergency amendment criteria may not apply.
Millstone is currently working on the above 3 documents just in case, if the weather conditions deteriorate and preparation of these 3 documents (NOED and Emergency Amd. for Unit 3 & Exigent Amd for Unit 2) will be completed early next week (Monday or Tuesday).
Bill Bartron wants to have a phone call on Monday (8/20) to discuss any updates on the UHS issues.
