Subject:
FYI: New DPO on Oconee ECCS Sump Screens In accordance with section (D)(3)(c) of the MD 10.159 Handbook, I am notifying you that I have received, screened, and accepted a new DPO.
The DPO (DP0-2006-002) raises concerns about new ECCS sump screens at the Oconee facility.
The submitter contends that the new sump screens can be impacted by jet impingement from an RCS cold leg break (LOCA) and that the licensee should be required to perform an analysis (per GDC-4) prior to installation.
I will soon be sending this DPO to Jim Dwyer for appropriate dispositioning.
Please feel free to contact me if you have any questions about this DPO or other DPO-related issues.
