The NRC review included the detailed RVI inspection plan that implements the elements of the RVI Aging Management Plan and fulfills License Renewal Application Commitment 30*Inspections of all MRP-227-A primary components (including over 4700specific inspections) are scheduled for the Spring of 2016 (IP2) and Spring of 2019 (IP3)*Industry MRP-227-A inspections performed to date have found no issueswith RV internals, other than isolated cracking of baffle-to-former bolts*Based on the industry OE, IPEC will have a baffle bolt minimum patternanalysis to document that cracking of small numbers of bolts has no impact on the structural integrity of the baffle-former assembly*IP2 is planning on replacing the split pins during the 2016 refueling outagewith cold-worked 316 stainless steel which is degradation resistant. IP3 replaced their split pins with cold-worked 316 stainless steel in 200916 Underground PipingUnderground Piping*Underground piping is defined as below grade, in contact with airand with limited accessibility*The program was changed to reflect new regulatory guidance
*All underground piping inspections due prior to entering the PEOwere completed at IP2. No adverse conditions were identified. All underground piping at IP2 has been coated with a qualified coating*Approximately 50% of the pre-PEO underground piping  inspectionshave been completed at IP3. The remainder of the inspections are scheduled for this upcoming Summer. No adverse conditions have been identified to date17 Buried PipingBuried Piping*Buried piping is defined as below grade and in contact with soil*All buried piping inspections due prior to entering the PEO have beencompleted at both IP2 and at IP3. The inspection results have demonstrated that the piping and the protective coating are generally in good condition.
Some minor coating degradation has been identified and corrected*There have been two exceptions where some moderate corrosion has beenidentified. One was a 2009 through-wall leak in the IP2 Condensate Storage Tank piping (discussed in the September 2009 ACRS) and the other was degradation in a Service Water line (two areas of degradation) in 2014 at IP3. Both locations have been repaired*In both instances, the affected piping remained structurally capable ofperforming its intended safety function18 Buried Piping (cont.)Buried Piping (cont.)*There is approximately 16,000 feet of buried piping within the scope oflicense renewal at IPEC (i.e. both units combined)*We have conservatively inspected in excess of 1,000 feet of buried piping ateach Unit (2,000 feet total)*IP2 committed to inspect (direct visual inspections) 20 carbon steellocations prior to the PEO (IP2 does not have any buried stainless steel piping)*IP3 committed  to inspect 11 carbon steel and 3 stainless steel buried pipinglocations prior to the PEO*IP2 committed to inspect 14 carbon steel locations and IP3 committed toinspect 14 carbon steel and 2 stainless steel buried piping locations during each of the 10-year period during the PEO19 Buried piping -CathodicProtection (CP)Buried piping -CathodicProtection (CP)*As a result of the site geology, a site wide CP system is not feasibleat IPEC*Targeted CP systems have been installed to protect specific areaswhere vulnerabilities have been identified*These include some City Water piping and Condensate StorageTank  piping at both IP2 and IP3*These CP systems provide some corrosion protection but not the fullprotection because of the non-conductive nature of the IPEC site geology*The main corrosion protection barrier for buried piping at IPEC is thebitumasticprotective coating*Since the full CP protection levels are not achievable at IPEC, theinstalled CP systems are not credited in establishing the inspection population which results in a larger direct visual inspection population20 Program ChangesProgram Changes*Examples of program changes*Buried Piping -Omission and corrections related to systems and componentscredited in AFW pump room fire (added IP1 river water, IP2 Circulating Waterand IP2 Instrument Air)*Metal-Enclosed Bus Inspection ProgramMetal-enclosed bus associated with Diesel Fire Pump is not required to startthe diesel since it only provides power to charge the batteries and was removed from program*Structures Monitoring Program-sump screens, strainers and flow barriers removed from program if they were changedto stainless steel in an air-indoor uncontrolled environment*External surface Monitoring program-some carbon steel piping and filter housing exposed externally to indoor air added tobe managed for loss of material by the program-carbon steel piping and filter housings and gray cast iron turbochargers exposedinternally to indoor air removed from program since they were associated with GT3 which is no longer credited21 Program Changes (cont.)Program Changes (cont.)*Oil Analysis Program-Added copper alloy greater than 15% zinc (inhibited) heatexchanger tubes which are exposed externally to lubricating oil*Tables in LRA revised to add or delete components based on annual updatesubmittals-programs looking for loss of material due to general, pitting and crevicecorrosion, microbiologically influenced corrosion, fouling and lining/coating degradation*Elastomer Degradation -materials added*Service Water System-Plastic piping exposed internally to raw water andexternally to indoor air added to a table in the LRA*Fuel Oil Systemadded copper alloy with greater than 15% zinc then removedbecause GT-3 no longer credited*Water treatment plant, City Water system, Lube Oil Systems -components added22 Concluding RemarksConcluding Remarks*Unit 3 is being prepared to enter the PEO aswas done for Unit 2*License renewal activities are being or will beconducted as if the plants had received a renewed license*Entergy continues to make investments into  theplants to ensure safe and reliable operation*IPEC is consistently operating with capacityfactors above 90%23 QuestionsQuestions24}}
