| Title | Need For Clarification on Condensate Storage Tank Suction Piping ASME Classification |
| Description | An unresolved item (URI) was identified because additional information is needed to determine if a performance deficiency exists regarding a discrepancy between various piping and instrumentation drawings (P&IDs) for the condensate and demineralized water storage/transfer systems, and the associated in-service inspection (ISI) drawings for the High Pressure Coolant Injection (HPCI) and Reactor Core Isolation Cooling (RCIC) piping and their related ASME Code safety classification. During this review the inspector noted a lack of clear description in assignment of piping safety classification shown on plant drawings for the aforementioned systems. The inspector observed that symbol convention used on the drawings was not reconciled with the requirements presented in the piping specification (M300, Rev 107, Section 3.0, ltem 1.0, Classification of Piping Components), and the P&lD legend. Entergy initiated CR PNP-2011-0127, which identified the need for a definition of the safety classification of the HPCI and RCIC suction piping from the condensate storage tanks to the first isolation valve within the auxiliary building. Appropriate code safety classification is necessary to ensure accurate in-service inspection requirements. Entergy\\\'s actions with regard to the resolution of the HPCI and RCIC piping safety classification (and boundary class changes) as shown on the referenced drawings remain to be reviewed and assessed to ascertain conformance with the applicable ASME Code (Section Xl) and NRC regulatory requirements. While the discrepancy may be related to a drawing error, it is possible that the subject piping is ASME Class 2 (or other), and should have been subject to ASME Code Class 2 (or other) design and testing requirements.
