Oyster Creek LR Outage Commitments Inspection Attachments: OC Priority Inspection Itemsrev-3.doc Dave, did we agree on 1 PM tomorrow (Wed)?

To facilitate tomorrow's discussion on OC drywell inspection, I've attached my DRAFT inspection task list. The inspection plan has not yet been written or approved.

As a remember, we've been directed to retain all documents & records regarding OC LR, in case a Hearing File is re-opened. That includes e-mails and attachments.

Thanks John Richmond 610-337-5220 1
