Re: MD 8.3 Review for Deterministic Aspects for Both Millstone Unit 2 Trips I agree Jim in that I don't think there is a reasonable chance at a potential greater than green issue here, based on what I know about it. Regarding the Safeties opening when maybe they shouldn't have to, I wouldn't necessarily consider them Inoperable for that reason. Maybe there is a nonconforming or degraded condition which is leading to the Safeties opening.....but by itself I don't know how efficient it would be from a resource (team) /potential safety significance standpoint.
Ray and I discussed this and one of the few transients we felt may be impacted would be a SGTR with a SRV opening and postulating failure to close.
Certainly the effect of degrading the boots, was not a significant safety concem.

We may consider updating this with "what we know now." I would agree that this Issue would require followup at the time it was written. However, at this point, If we still question the operability of the safeties or don't believe that the FW digital control is reliable, then we should not have allowed startup. It's my understanding that the licensee has determined a potential cause for the FW pump control issues: The results of the safety's opening Is under review. It might be helpful to get the SRAs to look at the risk associated with this issue. We should also get Information by the licensee on what they are doing and when it will be done.
I'm not sure the outcome of a SI (I don't think we would understand the Issues much more than we currently do and I would be surprised if we would get a greater than green finding) would support the resources needed to conduct the inspection. Please consider if a PIR sample could get to the bottom of this Issue.
I find that the literal interpretation of the 8.3 guidance will always result In an SI for nearly any trip or eventl

Mr. Trapp and Mr. Schneider, Please see the attached two forms. Together they appear to make a stong case for a special Inspection at Millstone Unit 2. This thought was discussed with the SRA, Mr. Patel, Mr. McDermott and Mr. Rogge to different extents. The second form recommends a special inspection and this "draft" recommendation was also discussed with Mr. Amer and CC'd to Mr. Doerflein. The remaining CCs on this email expressed questions about the completion of the forms at this moming's meetings.
Branch 6 received an action at the morning meeting to come to decision with respect to recommending a special inspection by Monday March 22, 2004.
