Large BOre Components Ranked High for Susceptibility from CHEMWORKS Evaluation. continued Condensate System Only one component was identified as having a negative time to Tmin. This was CD30TE02DS, the downstream side

• of a 24x24x20 tee on the condensate header in the feed pump room. The CHECWORKS prediction for the downstream side of the tee has a smatt negative hrs relative to the remainder of the components in the system and relative to the upstream side of the same tee. Other tees on the same header have been previously inspected and show no sigrnficant wear. The CHECWORKS model Includes UT data up to the 1999 RFO. The inspections on this system performed in 2001 indicate minimal wear. The 2001 inspection data witt be Input to CHECWORKS to better calibrate the model.

To inspect the components with the highest susoept*'fity as ranked byCHECWORKS and to obtain a more complete set of inspection data for the Condensate System inspect additional components between the No:3 feedwater heaters and the feedwaterpumps. Inspect CD30TE02 and CD30SP04 in 2004.

Moisture Separpr prains & Heater DrainSystem.

No components kientified as haVing negative times to Tmln, No components wera selected for inspection in 2001 or 2002 based on high susceptibility. However future operation under H-WC will change dissolved oxygen in system. A separate evaluation has been performed and components were selected for inspection in 2002. See Section LD below.

ES4ATE02, 30inch diameter tees Inside the condenser have negative prediction (-3426@Hn.) for lime to min wall. The negative times to Imin may be conservative based on the modeling techniques used. Refinement of the model of this system is in progress. The negative time to tmin is most likely a function of lack of inspection data vs. actual wear.

Due to exlernallagglng on this piping and the location.inside the condenser. no compoe ame selected for external UT inspection in 2004 based on high susceptibility. However, an opportunity to parfOlm an Internal visual inspection of all the Extraction -Steam lines inside the condenser during planed LP turbine work in the.2005 RFO maypresent itself. See Section LF below.

Note the short section of Al 06 Gr. B straight pipe on line 12'-ES-lA at the connection to the 36 lnch A cross around

VY Piping fAC Inspection Program PP 7028 _ 2004 Refueling Outage Inspection L ocation Worksheets/ Methods and Reasons for Component Selection LD:

Large Sore Components Selected to Calibrate CHECWORKS The CHECWORKS models have been upgraded to include the 96, 98, & 99 RFO inspection data. The 2001 and 2002 inspection data has been loaded however wear rate analyses are not complete at this time. In 2001 components on the higher temperature end of the Condensate System were inspected to calibrate the CHECWORKS models. The inspection data indicate minimal *wear and should reinforce the assessment oflowwear in the Condensate System. Additional components selected for inspection in 2004 in Section LB above will bs used to calibrate the CHECWORKS model.

Prior to the 2002 there was limited Inspection data for the Heater Drain system. The current CHECVIIORKS modelS (Pass 1 and some Pass 2) indicate low wear rates. During2002 a number.of new inspections were performed to obtain base line data prior to operation under GE Noble Metals HWC. NO additional components on the Heater Drain system will be inspected in 2004.

LE:

Large Bore Components subjected to off nonnal flow conditions identified by turbine perfonnance monitoring system (Systems Engineering Group).

The Systems Engineering Productk~a Variance Reports for 2002 & Shooe startup from 2002 (RF023) do not identify-.

any leaking valves. No other leaking valves or steam traps have been Identified (to date) using the Turbine Performance Monitoring (TPM) system. No components will be scheduled for the 2004 RFO based on the TPM

Internal visual inspe ton ofthis stub piece will be performed along with the 36' A cross around line. This extraction stream line (611 point extraction) has the highest quality sleam of all extraction lines which indicates. a relatively lower wear rala. Based on the 1996 inspection data for the catbon steel section, ES1ASP01 (inspection 96-07A) showing a small area of wall thickness less than 0.875 x nominal thickness, the expected changes in flow.regime due to power uprate, and that this is the only carbon steel section in the ES system, a repeat inspection to confirm actual wall thickness and also to obtain a baseline thickness prior to power uprate should be performed. Porfonn external UT Inspe-Ation of ESIASP01 in RF024.

Extraction Steam piping in the condenser has eXlernallagging which requires significant effort for removal when performing external yr inspections (plus there are significant staging costs). The piping is A335-P11. However an opportunity to perform an intemal visual inspecUon of all the Extration Steam lines inside the condenser during planed LP turbine work in the 2005 RFO may present itself.

The scope Includes locations identified using: previous inspection results,, the CHECWORKS models, Industry and plant operating experience, Input from the Tu"rbine Performance Monitoring System, the CHECWORKS study performed to postulate affects of Hydrogen Water Chemistry operation on FAC wear rates in plant piping, postulated power uprate effects', and engineering judgment.

(

The planned 2004 RFO Inspection scope consists, of 26 large bore components at 11 locations, internal Inspection of.6 of the BlInes of the turbine cross around piping,.and II sections of small bore piping. Given that it's a ull year from the start of the outage, any Industry or plant events that occur In' the interim or new infonnation may necessitate an Increase in the planned scope.

I am available to support planning and inspections as necessary. If you have any questions or need additional Information please conlsct me.

PP 7028 VY PIPING FLOW ACCELERATED CORROSION (FAC) INSPECTION PROGRAM RFO 24., SPRING 2004 PLANNED SCOPE External Ultrasonic Thickness (UT) Inspection of 26 large bore components at 11 locations. Includes some new locations, some repeat inspections for trending, and for a baseline prior to power uprate.

External Ultrasonic Thickness (UT) Inspection of 11 sections of small bore piping. Includes 5 sections on the turbine bypass valve 1 sealleakoff line if the line is not replaced during the outage.

0 Internal Visual Inspection of 6 of the 8 Turbine Cross Around Lines (36A to 360, 30C, & 300).

WO 02-4906 FAG Inspections -restraint removed with VYM 2003/009 BASIS I COMMENTS Component selection based on previous inspection results, the CHECWORKS models, industry and plant operating experience, the FAC HWC study, postulated power uprate effects, and engineering judgment.

• Similar numbers of components to be inspected as in previous outages,. VY inspects less than the industry average due to a simpler design (no reheat) and Chrome-Moly Extraction Steam piping.

For Large Bore Piping: The combination of previous inspections and the proposed 2004 inspections should provide a solid basis for a high degree of confidence against unexpected piping wall loss. We will have sufficient base line data to evaluate any negative trends from Power Uprate and HWC.

• Recent Small Bore leaks at VY and numerous ones at other plants require an increased and more intelligent focus on small bore piping.

Given that it's a full year from the start of the outage, any industry or. plant events that occur in the interim or new information may necessitate an increase in the planned scope.
