Rich My understanding is that Brendan has left until he arranges to get rehired as a retired annuitant and no one has been assigned as his replacement in the mean time. Therefore, can you please forward the following information to Sequoyah in reference to SOARCA. We would like to'arrange a telecom for Thursday morning.

Thanks!

Bob "The three sequences that will be used for the Sequoyah SOARCA analysis are as follows:

1. A LOOP (121-06-57) that leads to a LTSBO with TD AFW;

2. ISL-RHR caused by inboard and outboard MOV isolation valves failing open resulting in RCS pressure being applied to low pressure piping, the operator diagnoses but fails to isolate the ISLOCA;

3. A large seismic event that results in a STSBO without TD AFW In addition, attached are two information request. We are requesting that information for the immediate information request, be made available to us upon our arrival for the site-visit. The second information request have specific questions that may take a little longer to gather and, therefore, we are requesting that you provide that information by 3/7/2008. As we will explain in our telecom later this week, all the information we are asking for should be reasonably available and we do not expect you to perform any engineering analyses or to obtain information from your AE or NSSS vendor. During the telecom, we will also discuss the simplified process for forwarding the SOARCA-related information to the staff.
