It provides for rapid assessment of changes in or more stringent than the gulderines provided In D6217 to Justify the use of contamination level without the time delay required for rigorous laboratory D2276 only. procedures. It also provides a laboratory filtration method using a 0.8 micron filter. ASTM D6217 provides guidance on determining particulate contamination by sample filtration at an off-site laboratory. Neither method contains acceptance criteria or is more stringent than the other. Thus, there is no reason to use both methods. Since ASTM D2276 Is an accepted method of determining particulates and Is a method recommended by ASTM D975. to which VYNPS is committed by Technical Specifications, the D2276 method Is used at VYNPS.

Fuel additives are generally required for three reasons. These are to maintain the stability of the fuel oil, change the properties of the fuel oil (e.g. Increase the Ignition quality) or to prevent bacterial or mold growth in the fuel oil. The addition of blocides may degrade some of the other fuel oil properties such as Increasing the filterable solids loading.

For the past 10 years, VYNPS has been buying high quality fuel oil from Ultramar in Canada. Our deliveries are Umed to the arrival of new rail cars In Vermont from this refinery. We specify very high quality fuel oil and ensure that Itand the delivery trucks do not contain any contaminarnts. Monthly analyses of diesel fuel oilfrom the top, middle and bottom of the Main Fuel Oil Storage Tank have not produced any Indications of fuel oil deterioration or the presence of water or sediment. Since mold and bacteria grow Inthe water fuel ofl interface, we have no need for blocides.

Diesel generator performance associated with the quality of the diesel fuel oil has been excellent. Thus, there Is no need for fuel oil additives.

The diesel day tanks are 800 gallon tanks located above ground and adjacent to the emergency diesels Inseparate rooms. The design of the tanks does not provide access for cleaning. The fuel oil lor these tanks Is supplied from the Main Fuel Oil Storage Tank. The suction for the transfer pumps is located 4" off of the bottom of the tank. Chemisty samples both the Main Tank and the Day Tanks from the bottom of the tanks. Water and/or sediment In the Main Storage Tank would be detected prior to it being transferred to the Day Tanks.

Each of the Emergency Diesel Generators Is run for 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> monthly with each diesel using approximately 200 gallons of fuel oil per hour. This ensures that the fuel oil is turned over every month and that there are no stability Issues. There have been no Indications of water and sediment Inthe quarterly analyses from these tanks. Since VYNPS Is sampling from the bottom of these tanks and has not detected problems with the fuel oil, there Is no reason to drain and clean the tanks.

The John Deere Diesel Generator (JODG) Isrun under load monthly for I hour. This diesel uses 10 gallons per hour and the survellance requires verification of auto feed. The fire pump diesel Is operated during monthly and quarterly surveillance tests. Thus, the fuel In the metal tanks associated with the JDDG end fire pump diesels Is turned over frequently.

VYNPS may apply this re-analysis program to EQ components now qualified for the current operating term. A re-analysis program that meets the conditions defined In the GALL report for Important attnblutes,is an acceptable AMP for license renewal under option 10 CFR 54.21(c)(l)(gi).

LRA Appendix B.1.10 will be revised to add the following:

EQ Component Re-analysis Attributes The re-analysis of an aging evaluation Is normally performed to extend the qualification by reducing excess conservatism Incorporated In the prior evaluation. Reanalysis of an aging evaluation to extend the qualification of a component is performed on a routine basis pursuant to 10 CFR 50.49(e) as part of an EQ program. While a component life limiting condition may be due to thermal, radiation, or cyclical aging, the vast majority of component aging limits are based on thermal conditions. Conservatism may exist In aging evaluation parameters, such as the assumed ambient temperature of the component, an unrealistically low activation energy, or In the application of a component (de-enargized versus energized). The re-analysis of an aging evaluation is documented according to the station's quality assurance program requirements that require the verification of assumptions and conclusions. As already noted, important attributes of a re-analysis include analytical methods, data collection and reduction methods, nderlying assumptions, acceptance criteria, and corrective actions (Ifacceptance criteria are not met). These attributes are discussed below.

Analytical Methods:

The analytical models used Inthe re-analysts of an aging evaluation are the same as those previously applied during the prior evaluation. The Arrhenlus methodology Is an acceptable thermal model for performing a thermal aging evaluation. The analytical method used for a radiation aging evaluation Is to demonstrate qualification for the total Integrated dose (that Is, normal radiation dose for the projected Installed life plus accident radiation dose).

For license renewal, one acceptable method of establishing the 60-year normal radiation dose Is to multiply the 40-year normal radiation dose by 1.5 (that Is, 60 years/40 years). The result is added to the accident radiation dose to obtain the total integrated dose for the component. For cyclical aging, a similar approach may be used. Other models may be justified on a case-by.

case basis.

Data Collection and Reduction Methods:

Reducing excess conservatism in the component service conditions (for example, temperature, radiation, cycles) used in the prior aging evaluation is the chief method used for a re-analysis. Temperature data used in an aging

0.

0 evaluation Is to be conservative and based on plant design temperatures or on actual plant temperature data. When used, plant temperature data can be obtained in several ways, Including monitors used for Technical Specification CO, compliance, other Installed monitors. measurements made by plant operators during rounds, ard temperature sensors on large motors (while the motor Is not running). A representative number of temperature measurements are conservatively evaluated to establish the temperatures used in an aging evaluation. Plant temperature data may be used in an aging evaluation In different ways, such as (a) directly applying the plant temperature data Inthe evaluatlon or (b) using the plant temperature data to demonstrate conservatism when using plant design temperatures for an evaluation. Any changes to material activation energy values as part of a re-analysts are to be Justified on a plant-specific basis. Similar methods of reducing excess conservatism Inthe component service conditions used In prior aging 0 evaluations can be used for radiation and cyclical aging.

Underlying Assumptions:

EQ component aging evaluations contain sufficient conservatism to account for most environmental changes occurring due to plant modifications and events. When unexpected adverse conditions are Identified during operational or maintenance activities that affect the normal operating environment of a qualified component, the affected EQ component is evaluated and appropriate corrective actions are taken that may Include changes to the qualification bases and conclusions.

Acceptance Criteria and Corrective Actions:

The re-analysis of an aging evaluation could extend the qualification of the component. Ifthe qualification cannot be extended by re-analysis, the component is to be refurbished. replaced, or re-qualified prior to exceeding the period for which the current qualification remains valid. A re-analysis Is to be performed Ina timely manner (that is, sufficient time is available to refurbish, replace, or re-qusarfy the component i the re-analys Is unsuccessful).

55 B.120-K-01 As stated In IRA Section B.1.20. exception note 1, flash point is not Closed For those components that do not have regular oil changes, please provide determined for sampled oil because analyses of tilter residue or particle the basis for Note I (not determinik*g the flash point for the sampled oil). count, viscosity, total acidtbase (neutralization number), water content, and metals content provide sufficient Information to verily the on does not contain water or contaminants that would permit the onset of aging effects.

Added Response: Fuel dilution Is measured on EDG lube o11,rather than determiming the flash point.

In lieu of performing Rash point testing on the Emergency Diesel Generators, Diesel Driven Fire Pump and the John Deere Diesel Generator, a test for fuel and water by % of volume is performed. This test accomplishes the same goal as the flash point test but is more prescriptive then the flash point test.

There could be two factors that affect the flash point of the oil; the addition of fuel that would lower the flash point or the addition of water that would raise the flash point The worst case would be a combination of the two. By determining the % by volume of both fuel end water, the analysis can determine the cause of the change In flash point without having to conduct additional tests and corrective actions, If required, could be implemented on a timelier basis.

Additional tests to determine the *Heaith of the diesels are; total base number (TBN), viscosity, SAE Grade, Total Soot, and Spectrometals analysis (for wear metals and additives). The results of these analyses are trended to determine the total health of the diesel and the quality of its lubricating oil.

2) Preventive actions - The GALL XI.S7 program Inci*iles no preventive actions.

3) Parameters Monitored -The aging effect requiring management for concrete structural components of the Intake structure Is loss of material which Is consistent with GALL Volume 2 Item IL.A6-7. The parameters monitored from the GALL XLS7 program apprlable to loss of material are consistent with those monitored by the Structures Monitoring Program. The guidance for Inspections of concrete InSection C.2 of RG 1.127 Is consistent with the guidance In ACI 349.3 used Inthe Structures Monitoring Program.

4) Detection of Aging - GALL XI.S7 Identifies visual inspection methods as the primary method used to detect aging. The Sructures Monitoring similarly uses visual Inspection methods as the primary method used to detect aging In concrete structural components. GALL X.S7 Identifies Inspection Intervals of five years. The Struchres Monitoring Program identifies similar Inspection Intervals of three years for accessible areas, ten years for Inaccessible areas and opportunistic Inspections for buried components.

5) Monitoring and Trending - Monitoring Is by periodic Inspection for both the GALL XI.S7 and Structures Monitoring Programs.

6) Acceptance Criteria - Acceptance criteria Is not Identified In RG 1.127.

(Note: This question Is arbitran'ly inked to these systems that have functions that met 10 CFR 54.4(a)(2) for physical the first Item of Table 3.3.1-13-1) Interaction was done separately from the review of systems with Intended functions that met 10 CFR 54.4 (a)(1) or (a)(3). The results of this review therefore needed to be presented separately so that they could be distinguished from the 10 CFR 54(a)(1) and (a)(3) review. Table 3.3.1-13 would be the next sequential table number after the remainder of the auxiliary system tables. To indicate Inrvdual systems included in the aging management review for (a)(2). Table 3.3.1-13 Is subdivided by system. For example, Table 3.3.1-13-1 Isfor the augmented off gas system, a system which only has components Included for (a)(2). For the core spray system, Table 3.3.1-13-6 shows the components included for (a)(2) but since the system is also In scope for other reasons, Table 3.2.2-2 shows the components Included for 54.4(a)(1) and (a)(3). This numbering system was chosen so that these systems and the components that had Intended functions unique for 54.4(a)(2) could be uniquely Identified and reviewed separately. This allows a reviewer to clearly distinguish which component types in a system were Included for 10 CFR 54.4(a)(2) for physical Interaction. Since most of these systems are auxilary systems they were added as part of the auxiliary systems section.

Aging Effects - Section 3.62.2.3 Transmission conductors are un-insulated, stranded electrical cables used outside buildings In high voltage applications. The transmission conductor commodity group includes the associated fastening hardware, but excludes the high-voltage insulators. Major active equipment assemblies Include their associated transmission conductor terminations.

The aging effect for transmission conductors found InIndustry reviews are loss of conductor strength and loss of material (wear).

The prevalent mechanism contributing to loss of conductor strength of an ACSR transmission conductor Is corrosion, which includes corrosion of the steel core and alumwnurn strand pitting. Corrosion InACSR conductors Is a very slow acting mechanism. and the corrosion rates depend on air quality, which Includes suspended particles chemisry, S02 concentration Inair, precipitation, fog chemistry and meteorological conditions. Air quality in rural areas generally contains low concentrations of suspended particles and SO2.

which keeps the corrosion rate to a minimum. Teats performed by Ontario Hydroelectric showed a 30% loss of composite conductor strength of an 80 year old ACSR conductor due to corrosion.

ACAR conductors are more resistant to loss of conductor strength since the core of the conductor Is an alloy of steel and corrosion resistant metals.

AMR conclusions regarding ACSR conductors conservatively bound ACAR conductors.

The National Electrical Safety Code (NESC) requires that tension on installed conductors be a maxmumn of 60% of the ultimate conductor strength. The NESC also sets the maximum tension a conductor must be designed to withstand under heavy load requirements, which Includes consideration of Ice, wind and temperature. These requirements are reviewed conceming the specific conductors included In scope at VYNPS.

The 4/0 ACSR conductors have the lowest initial design margin of any transmission conductors Included Inthe AMR. The Ontario Hydro test and the NESC requirements illustrate with reasonable assurance that transmission conductors wil have ample strength through the period of extended operation.

Therefore, loss of conductor strength due to corrosion of the transmission conductors In not an aging effect requiring management for the period of extended operation.

Loss of material due to mechanical wear can be an aging effect for strain and suspension Insulators that are subject to movement caused by transmission conductor vibration or sway from wind loading. Design and installation standards for transmission conductors consider sway caused by wind loading. Experience has shown that transmission conductors do not normally swing and that when they do swing because of substantial wind, they do not continue to swing for very long once the wind has subsided. Wear has not been Identified during routine inspection; therefore, loss of material due to wear Innot an aging effect requiring management This report documents a review of Industry OE and NRC generic communications related to the aging of transmission conductors In order to ensure that no additional aging effects exist beyond those previously identified. This report also documents a review of plant-specific OF, which did not identify any unique aging effects for transmission conductors.

Auxiliary Systems, necessary and appropriate for this program? The Identified enhancement to AMP 8.1.30, Water Chemistry Control -

Auxiliary Systems is to enhance procedures to flush the John Deere diesel cooling water system and replace the coolant and coolant conditioner every three years.

A program Is necessary to manage loss of material and fouling of carbon steel and copper alloy components in the John Deere diesel cooling water system for the period of extended operation. Due to the size and configuration of the system, periodic sampling of the coolant was deemed unrealistic and the decision was made to flush the cooling water and replace the coolant and coolant conditioner every three years. While this task could have been Itukdxed In the Periodic Surveillance and Preventive Maintenance program, it was Included Inthe Water Chemistry Control - Auxiliary Systems program to be consistent with other components exposed to treated water, which are managed by water chemistry control programs.

As stated InLRA Section B.1.30.1. rather than sampling, procedures will be enhanced to flush the John Deere diesel cooling water system and replace the coolant and coolant conditioner every three years. (License Renewal Commitment 26)

Because of this, comparison with the NUREG-1 801 programs generates many exceptions and explanations which detract from the objective of the comparison. What Is really needed is that WNPS follow the version of ASME Section XI that Is approved for use at VYNPS and accepted by iaw in 10CFR50.55(a). As this Is the case, the Inservice Inspection and Containment Inservice Inspection Programs are presented as plant-specific programs so they can be Judged on their own merit without the distraction of numerous explanations of code revision.

178 What Is the exam history, results, schedule and currrent status of shroud I-I8 In RFO 19 (1996) Vermont Yankee performed an Inspection of welds H8 and Closed and H9 welds? H9 which meets the requirements of BWRVIP-38 for a baseline examination.

The followig describes the rationale for this statement The baseline strategies for welds H8 and H9 are shown In Figures 3-4 and 3-5 of BWRVIP-

38. The load multiplier Is determined from Figes 5-1. In Vermont Yankee's case this Is a 0.41. The flaw tolerance Is determined from figures 5-1 (for H8) and 5-2 (for Hg) for plants with support legs. For both welds the flaw tolerance of 100 %. The minimum examination coverage for a flaw tolerance of 100% is 10% for both H8 and Hg. The coverage was 25% for weld H8 and 22% for weld Hg during the RFO 19 (1996) examination. No flaws were found. Therefore an adequate baseline of welds H8 and H9 was performed.

No welds other than H8 and H9 require examination Is accordance with BWRVIP-38 for a plant with Vermont Yankee's core shroud support configuration. The NRC requires Inspection tooli and methodologies be developed that allow the welds In the lower plenum to be made accessible.

This requirement applies to the VYNPS shroud support leg welds. This inspection remains an open Ierm with the NRC per response to BWRVIP-38.

The re-inspection Interval Is established In BRWVIP-38, Paragraph 3.3.2. that states "¶fno flaws were found during the previous inspection, re-Inspections are performed on ten-year Intervals HtUT techniques were used...' The RFO 19 (199%) H8 and H9 examination was an ultrasonic test augmented with eddy current and no flaws were found. Therefore the re-Inspection Interval Is ten years IHUT techniques are used, and six years If EVT-1 techniques are used (but see below). Accordingly, re-Inspection of H8 and H9 were re-Inspected InRFO 25(2005). by EVT-1 nine years following the baseline exam.

The peak fluence values were calculated in accordance with Regulatory Guide 1.90 (See LRA section 4.2.1) and include conservatisms to ensure they are maximum values. Given these factors, the recirculation Inlet nozzles do not exceed the 1E17 threshold for neutron embrittlement Even If the fluence at the nozzle slightly exceeds 1E17 threshold, the correction factors from Regulatory Guide 1.99 are very small when Just above the irrit.

The feedwater nozzle thermal sleeves are InTable 3.1.2-1 with an Intended function of pressure boundary. Cracking of the thermal sleeves Is managed by Inservnce Inspection and Water Chemistry Control - BWR.

Further review of the thermal sleeve design (to determine exactly how ISI inspects them) determined that the VY sleeves are not welded In place, rather they are an Interference fIt As such, there Is no weld to the pressure boundary piping thaI can be examined by ISI.

Given that there Is no pressure boundary weld, these sleeves are not part of the pressure boundary. As such they have no Intended function for license renewal, and with no Intended function they are not subject to aging management review1. Therefore, Vermont Yankee will amend the license renewal appricatfon to Indicate that the feedwater thermal sleeves are not subject to aging management review.

The feedwater thermal sleeves have no non-safety affecting safety related (a2) function. They are completely contained within the feedwater piping and cannot spray or leak on other equipment. The feedwater thermal sleeves are a part of the feedwater piping Inside the vessel, and failure of that piping does not defeat the deivery of water to the vessel annulus, as any leakage also goes to the vessel annulus.
