- Rick, I found the PSEG notification concerning the missed surveillance. I also have a call in to Bill Mattingly, Reg Assurance Mgr, to get clarification. Let me know if this is what you need.

CONDITION DESCRIPTION/LOCATION (THE INAPPROPRIATE ACTION AND ITS NEGATIVE EFFECT/INCLUDE A DETAILEDLOCATI.ON DESCRIPTION):##
The required ASME Section XI Pressure Testing for 'the buried AuxiliaryFeedwater piping required by the ER-AA-330-001 and OU-AA-335-01 5 procedures were not performed. The ISI program manager has found no evidence of testing. These procedures implement the requirements of 1 OCFR50.55a, The system pressure test boundary drawing (S2-SPT-336-0) identifies the piping as YARD piping not buried piping. This is applicable to both Salem Units. The Salem unit 1 piping however is being replaced and will be hydro tested to code requirements prior to being placed in service.
ACTIVITIES, PROCESSES, PROCEDURES INVOLVED:
ER-AA-330-001,Section XI pressure Testing OU-AA,-335-01.5, VT-2 Visual Examination WHY DID CONDITION HAPPEN?
The system pressure test boundary drawing (S2-SPT-336-O) identifies the piping as YARD piping not buried piping, However, it is commonly understood that it is buried pipe.
CONSEQUENCES:
The implementation of the ASME Section Xl pressure testing may not have been completed in the current inspection interval as required. However, the in-servic~e testing required by S2.OP-ST.AF-0007, In-service Testing of Aux Feed Water Valves Modes 4-6, infers that the functional requirements of the test have been met. The test records pump dp and pump flow. The flow measurement occurs down stream of the buried section of piping. The pump dp is taken at pump. This ST uses the 21 and 22 AF pumps. Review of the IST data taken (12 STs since May 1997) shows that the pump dp and flows have been constant (considering instrument and instrument reading inaccuracies: since 1997. No ST hasexceeded its upper or lower iST limits, The QuarterlySTs provide'evidence that the 21 and 22 AF pumps are'not degraded.. The'ability of the AF pumps to achieve required flow downstream of the buried piping section at a consistent pump dp~provides assurance that the buried piping system condition has not changed. The test also confirmsothe code requirement that flow is not impaired.
Salem Unit 1 piping is out of service, is being replaced, and will be subject to Code required pressure testing prior to being placed in service.

Notification 20459689 AFW System TS 3.7.1.2 requires that the AFW system flow paths shall be operable. TS4.0.5 requires ASME Class 1, 2 and 3 components to be tested in accordance with ASME Xl. Since the ASME test was apparently missed, we should treat thisas a missed TS surveillance of the buried pipe flow path. TS'Surveillance Requirement 4.0,3 states that if the surveillance is not performed within its specified frequency (in this case two (2) cycles), a delay of up to the limit of the-specified frequency is allowed IF a risk evaluation is performed for the delay greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> and the risk impact is managed.
REQUIREMENTS IMPACTED:
ER-AA-330-001, Section Xl pressure Testing OU-AA-335-015, VT-2 Visual Examination ADVERSE PHYSICAL CONDITIONS:
No adverse physical condition.

Engineering Director KNOWLEDGEABLE INDIVIDUALS:
Tim Giles, Ed Maloney, TomRoberts, H. Berrick, E. Villar REPEAT OR SIMILARCONDITION:
No IMMEDIATE ACTIONS AND RECOMMENDED ACTIONS:
Engineering to provide risk assessment for Unit.2 Auxiliary Feedwater buried pipe to allow delay in test until next refueling outage (2R18). The risk impact associatedwith thisevaluation shall be managed.
Perform required In-service Pressure Testing in next outage on unit 2 (2R1 8). Buried piping on unit 1 will be tested prior to returning to service during current 1 R20 refueling outage.
Revise Ul & U2 Salem In-service Inspection Program Long Term Plans to identify all buried Section XI piping systems and required testing.
