Description of Modification: (Mechanical/Electrical Modification, Safety Function Bypassed, Auto Feature Disabled, Etc.) (Attach W A P F 0020.04 for a l l electrical TMs/MMs and VYAPF 0020.05 for a l l mechanical TMs/MMs) : Provide a replacement seal desisn at the intersection of the drvwe l l shell and the concrete floor at elevation 238. The d w e l l s h e l l will be stripped of paint within a f u l l circumferential six inch band f 2 / - 0 measured from the bottom of t h e existina lserimeter kewav and recoated w i t h an amxoved, Service Level 1, protective coatinq. Concurrent with 5 these activities an ASME IWE inspection of the shell will be\$
conducted bv Project Encheerins. This nroiect is beins performed, as a result of the IWE inspections conducted durincr RFO 21. These Q inspections revealed that some lsittins was occurvins in this area. %
Research into this issue indicates that the oricrinal seal had been?
removed and an effective reconfiguration of the seal was not d performed. Reference VYM 2000/16, D w e l l Seal Project Scope Memo Q:
%?
w and VYM 2 0 0 0 / 4 3 , D w e l l Protective Coatins Oualification Memo.
Major Change: The C Z l l coating failed to bond to the prepared 9 surface and cam not be aualified as a Service Level 1 Coatincr,<
coatincz will be scram8 from the area that received the apnlication to remove loose material and create a sound ticrht substrate for adhesion of the en- coating. Vacuum blastinn will be used to grenare the area of the shell that interfaces with the seal to tzenare for the installation of the seal as detailed on 5920-12789. The seal will still nrovide the function it was orisinallv designed for in that it will Drovide a moisture barrier to mitigate water enterina the shell to concrete interface, The sealant in direct contact with the gregared steel surface is acceptable based on the manufactures technical literature for surface pre-ation. Steel in direct contact with grout is protected by the gassivating effect of the arout. In areas where CZ 11 remains, added protection is nrovided by the zinc, The drywell shell will receive a n axmlication of Carboline 890 which w i l l not meet Service Level 1 Criteria. The single coat.
azmlicatioa for one owrating cycle has been verified with Carboline Cornoration as an accentable amlication until a permanent remedy is achieved. Corrective actions for the unqualified coatina in this area will be tracked mer an Ae-0028 for nossible resairs durina RFO 23. ECCS strainer loadinqs are calculated in VYC-1677. Review of VYC-1677 documents that based on the size of the installed strainers, paint loadins has minimal affect on NPSH. Additionally, VYC-1677 assumes that all the VYAPF 0020.03 AP 0020 Rev. 21 Page 1 of 9
TM/MM CONTROL SHEET (Continued) affected paint within the zone of influence detaches f r o m the LOCA jet -act and loads on the strainer. Recent BWROG testing has documented that sianificant amounts of the Paint, especially with the VY armroach velocities, will settle to the bottom of the torus. Therefore, based on this review of VYC-1677, the addition of this small amount of notentially failed paint will have PO
-act on the onerability of the ECCS suction'strainero.
Describe how modification changes component/system weration: This modification will have no effect on comonent / system operations.
The new seal is similar in form, fit and function to the oriainal desim.
System Engineering Group input obtained and incorporated in design.
nFd---' / 5hh Originator Date Reason f o r Change: Current seal confiauration does not z>rovi.de sufficient protection acrainst corrosion of the drvwell shell.
Reliance on existina saint (primer) for corrosion protection has not proven adequate by itself. An enuineered seal and protective coatinq svstem anplied in accordance with recocrnkzed standards will -r>rovi.dean effective moisture barrier at this junction. Major Change: A nrotective coating w i l l be analled, but it will not be gualified as a Senrice Level 1 Coatincr.
Describe design requirements (wire size, pipe material, etc.):
Ernbecco 885 Grout - fill for existins kevwav, Closed Cell polyethylene tane 3M #481 - bond breaker, Dow Cornincr 795 buildins sealant - silicone based elastomer, Carboline inoruanic zinc primex, Carbo Zinc 11 SG - nrirner coat, Carboline 890 - m o w top coat. All materials to be Safetv Class 2. Major Change: The coatings have been changed to an unaualified coating. Residual unaualified CZ 11 can remain on the drvwe11 shell after scraning the loose material and restorina the surface to a sound tight substrate consisting of bare steel and ticrhtlv adhered CZ11. The shell will be vacuum blasted in the area of the elastomer seal (1 inch wide strine -0 + 1") to remove the C Z l l and ex^ose the profile that exists on the steel from the previous surface preparation efforts. A single coat of 890 will be asnlied to the area above the seal.
Describe any potential hazard presented by the modification (e.g.,
fire, flooding, rad consequences, etc.) and provide a detailed assessment if appropriate (UND9302TPl): Methanol vapors are evolved durina the sealant curins Drocess.

Based on a review of the following questions, determine i f the proposed activity has the potential to impact safe operation of the facility and requires a 10CFR50.59(a)(2) evaluation. A "YES" answer to any of the questions 2 through 25 requires that a written 10CFR50.59(a)(2) evaluation be perf';;rmed. Either evaluation may require an FSAR change in accordance with AP 6036 or a TRM change in accordance with AP 0060. These questions need to be answered based on a review of the activity (i.e., procedure change, Temp. Mod.,
Equivalency Eval., Lineup Deviation, etc.) vs. the requirements of the FSAR or interim FSAR changes, the TRM and Tech. Specs. The originator should provide a response to "NO" answers that are potentially applicable to provide a basis f o r the conclusion.

Comments on MM 2000-010 Related to Potentid ImDact on ECCS Suction Strainer Debris Loads The MM introduces some new material into the Drywell, consisting of grout, polyethylene sheeting as a bond breaker, and a silicone sealant, to fill in a gap between the concrete floor at the 238 ft elevation and moisture barrier to from an For example, rather than use the guidelines to determine a Zone of Influence associated with a jet of water/steam from a LOCA,the sizing was conservatively based on Yz of the material in the drywell. In addition to the insulation material, the sizing also includes accommodations for sludge, rust flakes, and an allowance for qualified coatings directly impinged by water/steam jets. It was also determined during the performance tests of the strainers that, under post-DBAWA conditions of recirculation flow,only fiber is collected on the strainers,Le. heavier material sinks to the bottom of the torus. If it is conservatiVely assumed that M of the polyethylene sheeting is deposited in the torus, its total surface area would be about 12 sq ft, which is significantly less than the surface area of any one of the four strainers.
Per telecon with B Slifer, VYC-1678, the debris loading calculation for the torus is not affected by the materials installed under mod 2000-010. The maximum debris loading occurs with a pipe break outside of the 238" elevation area and is the bounding condition for the torus loading issue.

Subject:
Sil-Pro Material Used in Drywell Seal Job, MM 2000-010 --
The Sil-Fro bonding agent that was specified to be used in the Installation Instructions,step 7.13, page 8 of 11, did not have an issue ticket with the material, and therefore no issue ticket was pIaced in this J.O.File for this material.
The Sil-Pro used was from stock material that was stored in the NPS Laborers gang box. The material was assumed to have been purchased by the construction contractor for another job. The original container is not available to record lot or batch number of the material.
Lead Air Sampling Protocol for Drywell Seal Work Job Revision 1 Initial Sampling:
BZAs will be placed on the worker that is expected to receive the highest exposure of each crew. (2 samples)
BZAs will be placed on one other worker of each crew. (2 samples)
Two low volume general area lead air samples will taken in the area of both work groups on the 238 level of the Drywell. (2 samples)
Two additional general area Iow volume lead air samples will be placed on the Drywell 252 grating directly above the work groups. (2 samples)
One low volume air sampler will be run outside the Drywell as a blank.
(1sample)
This is a total of 9 samples.
Procedure:
I. Change all these samples out after the first 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> of work.
- 2. Log them and handle them per AP-0549.
- 3. Transport them to the chemistry lab ASAP.
- 4. Chemistry shall analyze the samples when they are delivered. The sample results are needed as quickly as possible.
- 5. Chemistry will deliver the results to Remi Morrissette or Doug Bruce for evaluation of the lead levels.
- 6. We will continue to sample until the lead work is complete.
The low volume samples will be changed out shiftly The workers should keep their BZAs for the entire shift
- 7. After initial sampling we will have a total of 18 to 20 samples each shift for a period of three days.
VYNPS Corrosion of the low part of the drywell is effectively prevented lly the following methods:
I 1. The ambient temperature of the drywell is maintained between 1350F and 165OF by forced draft air cooling units which continually circulate the 1 air in the drywell. These units are, in turn, cooled by the Reactor I Building Closed Cooling Water System and the moisture is removed from the air. Consequently, the steel plating surfaces will remain dry, thus minimizing any corrosive action.
- 2. The lower portion of the drywell interior and exterior surfaces are protected from any contact: with the atmosphere by complete concrete encasement. This effectively prevents any corrosive action on the plates in that area.
- 3. All interior and exterior drywell surfaces which are exposed to the atmosphere a r e protected f r d corrosion by application of a corrosion resistant coating material.
There is a remote possibility that the height of ground water during a given period could exceed the elevation of the extreme lower portion of the *ell.
Nevertheless, it is not considered possible for this ground water to reach the steel plating, assuming a crack in the foundation concrete. The bases for this conclusion are as follows:
- 1. The monolithic foundation concrete structure is greater than 18 feet thick below the drywell and is divided into three separate pours i n the horizontal plane. It is considered almost impossible for a crack to propagate completely through any given pour because of the thicknesses involved and the bedrock foundation.. Even if this were to occur, it is not considered possible for any given crack to propagate beyond the joint between pours.
- 2. Water-stop material is used at all foundation concrete joints between pours, both in the horizontal and vertical planes. This design assures that water will not propagate along any given joint in the concrete.
The possible effects of a given thermal gradient through the foundation concrete have been considered. Based on the concrete thicknesses and possible temperature differentials, it is not considered possible for any thermal gradients to exist which would damage orptherwise affect the structural 12.2-15 d 1 Revision 13 J E-=
VYNPS occur from the condenser (based on methodology in SRP 15.4.9). The leakage path was assumed to be out of the turbine hall and into the Control Room intake.
The total 30-day thyroid and whole body gamma doses excluding mairisteam isolation valve leakage have been calculated to be 8.8 rem and 0.10 rem, respectively. The 30-day thyroid and whole body gamma doses from main steam isolation valve leakage have been calculated to be 18 rem and 0.002 rem, respectively. The above calculated doses to the Control R o o m occupants are within the limits specified in Criterion 19 to 10CFR Part 50.
14.9.1.6 Materials Within the Containment No material within the primary containment will fail by decomposition or corrosion and affect vital systems. The GE program for determining the effect of hydrogen evolution by radiolysis is discussed in Appendix B of the FSAR. See also Section 5 . 2 .
The interior pressure boundary surfaces of the drywell and torus were originally prime coated during construction with an inorganic zinc paint primer that will withstand the accident environment without failure {Carboline CZ-11). This coating was radiation and DBA tested at Oak Ridge National Laboratory ( O W L Log Book No- A 7562; 11-29-6 and Log Book No. A 9675, A 1 0 - 1 3 - 3 3 ) and tolerated radiation doses of LE9 rads without failure.
The drywell primer w a s topcoated with a Keeler & Long epoxy (No. 7475). The torus primer was topcoated with a Keeler & Long phenolic paint (No. 7230).
During RFO 20, 1998, the immersion area of the torus was steel grit blasted and recoated with an inorganic zinc paint (Carboline CZ-11SG) and a belly-band of phenolic paint (Carboline 368WG) was applied from approximately one foot above and one foot .I-below normal water level to prevent tiger striping. The coating system used is a qualified Nuclear Service Level 1 coating in accordance with ANSI 101.2-1972 and was applied under an approved quality assurance program to ensure compliance with ANSI N l O l .4- 1972. 12 In response to NRC Bulletins 79-01 and 79-018, an extensive re-evaluation of post-accident radiation fields and equipment qualtfications has been performed, was submitted or review and was approved (References Y , Z , A l and El).
14.9.1.7 Conclusion All the necessary safety-related systems and equipment are capable of performing their intended functions in t h e presence of either the design basis radiation sources or postulated TID-14844 sources without exceeding the limits of 10CFR100.

DOW CORNING 795 silicone building sealant should not be applied:
-oil-based To building materials that bleed oils, plasticizersor solvents - materials such as impregnatedwood, caulks, green or partially vulcanized tubber gaskets or tapes
- In totally confined spaces, because the sealant requires atmospheric moisture for cure
- When surface temperatures exceed 49" C (120' F)
- To frost-laden or wet surfaces
- Where painting of the sealant is required; the paint film will not stretch with the extension of the
-sealant and may crack and peel To surfaces in direct contact with food; this sealant has not been tested to determine its status under Federal Food and Drug Administration regulations. For applications involving food contact, DOW CORNING 999-A silicone building & glazing sealant is recommended
- In belowgrade applications
- For use as an interior penetration firestop sealing system
- In horizontaljoints where abrasion and physical abuse are likely to be encountered
- For continuous immersion in water Composition and Materials: DOW CORNING 795 silicone building sealant is a chemically stable, one-part, ready-to-use material that has the consistency of toothpaste. This consistency remains uniform over a wide temperature range from -37 to 71" C (-35 to 160" F) allowing the sealant to be applied easily at most temperatures.
Priming is not required for most common construction substrates.
In cases where doubt exists, a sample should be tested andlor a trial installation placed on the project.

- 4. TECHNICAL DATA DOW CORNING 795 silicone building sealant is virtually unaffected by sunlight, rain, sleet, snow, ultraviolet radiation, atmospheric contamination, ozone and temperature extremes. Its uni ue weatherability enables it to retain original desi n properties even after years of exposure. joint R
performance does not change significantly wi aging or exposure to weather. Seals remain watertight and weatherproof. Cured sealant will not harden in cold to -54" C (-65" F) or soften with heat to 149" C (300"F). It will not become brittle, or tear or crack, and the silicone sealant stays flexible indefinitely.
http://www.roancorp.com/ 6/7/00
Dow Corning 795 Structural GIazing & Weatherproofing Sealant - RO-ANOnline Page 3 of 5 DOW CORNING 795 silicone building sealant is compatiblewith reflecthe glass, most laminated glass, most insulating glass units, and acrylic and polycarbonateglazing sheets.
DOW CORNING 795 silicone building sealant has been tested by UL for performancewhen exposed to flames. The material, when in a joint configuration sealing system without a protective steel cover plate, meets the two-hour fire resistance ratings with or without the use of mineral wool as a backer.
This is in accordancewith Standard UL 263 (ASTM E 119). DOW CORNING 795 silicone building sealant also holds up when exposed to a high-pressure water force without a protective cover plate.
- 5. INSTALLATION Joint Design: A thin bead of silicone will accommodate more movement than a thick bead. DOW CORNING 795 silicone building sealant should be no thicker fhan 1/2 inch (12.7 mm) and no thinner than 1/8 inch (3.2 mm) for joints where excessive movement is expected. Ideally, the ratio of joint width to seafant depth should be about 2:l , when appropriate.
Open-cell, polyurethanefoam or closedGel! polyethyleneare the recommended back-up materials for most joints; use polyethylenetape for joints too shallow to allow backer rod. These materials permit application of a thin bead and act as bond breakers, which allow the silicone sealant to stretch freely with the joint.
The width of building expansion joints varies because of seasonal and daily changes in temperature. If DOW CORNING 795 silicone building sealant cannot be installed when the design width is approximately halfway between the dimensional extremes, the designedjoint must be at least twice the total anticipatedjoint movement Good architectural practice calls for joint design of four times the anticipated movement due to construction tolerances and material variations.
Glazing rabbets and joints should be designed to allow installation and retention of the bond-breaking, back-up material during the installationand curing of DOW CORNING 795 silicone building sealant Lap shear joints should have a bead width that is equal to, or greater than, the total anticipated movement.
Fire Rating: In a properly designed joint, the silicone sealant can be applied without a cover plate and with or without a mineral wool backer material, yet still be fire resistant.
Joint Dimensions: Small curtainwall panels and lites should allow a minimum width of 118 inch (3.2 mm) for the sealant bead. Larger panels and likes, or those in which a great deal of movement is expected, should allow a minimum width of 3/16 to 1/4 inch (4.8 to 6.4 mrn) for the sealant bead.
Glazing of pfastic lites, and panels fabricated from plastic, require larger than usualjoint dimensions due to the plastic's high coefficient of thermal expansion.
Preparafory Work: Clean all joints and gfazing pockets, removing alf foreign matter and contaminants such as grease, oil, dust, water, frost, surface dirt, old sealants or glazing compounds and protective coatings.
. a Porous substrates should be cleaned where necessary by grinding, saw cutting, blast cleaning (sand or water) or mechanical abrading, or a combination of these methods as required to provide a sound, clean, dry surface for sealant application. Dust, loose particles, etc., should be blown out of joints with oil-free compressed air or vacuum cleaned.
Metal, glass and plastic surfaces should be cleaned b mechanicalor solvent procedures. Detergent Y
or soap and water treatments are not acceptable. In a Icases where used, solvents should be wiped on and off with clean, oil- and lint-free cloths.
CAUTION: When using ffammable sorvents, keep-away from heat, sparks and open flames. Use only with adequate ventilation. Avoid prolonged breathing of vapor and prolonged or repeated skin contact Always foflow solvent container label instructions.
Priming: When using DOW CORNtNG 795 silicone building sealant, priming is not usually required.
Prior to general job use, it is always recommended that a bead of sealant be applied on the substrate material to test adhesion. For structural applications, contact Dow Corning for consuftation.
Masking: Areas adjacent to joints may be masked to assure neat sealant lines. Do not allow masking tape to touch clean surfaces to which the silicone sealant is to adhere. Tooling should be com leted in one continuous stroke immediately afersealant application and before a skin forms.
MasKing should be removed immediately after tooling.

Dow Corning 795 Structural Glazing & Weatherproofing Sealant - RO-AN Online Page 4 of 5 Methodof Appllcationr Install back-up material or joint filler, setting blocks, spacer shims and tapes as specified. Apply DOW CORNING 795 silicone building sealant in a continuous operation using a positive pressure adequate to properly fill and seal the joint. Tool or strike the DOW CORNING 795 silicone buiiding sealant with light pressure to spread the material against the back-up material and the joint surfaces. A tool with a concave profile is recommended to keep the sealant within the joint.
In glazin , tool the sealant applied at the sill so that precipitation and cleaning solutions wilf not pool.
DOW C8RNING 795 silicone building sealant can be applied at outdoor temperatures as low as -29" C (-20" F) provided that surfaces are clean, dry and frost-free.
It is imperative that uncured silicone sealants are not allowed to contact nonabradable surfaces, such as polished granites, metal or glass. Because excess silicone sealant cannot be completely removed with organic or chlorinated sohrents, these surfaces must be masked or extreme care taken to prevent any silicone sealant from contactin them during sealant application. Once an uncured sealant -
1 contacts the surhce, it will leave a Im that may change the aesthetic surface characteristicsof that substrate.
In cases where uncured sealant is inadvertently applied to adjacent surfaces, the sealant should be cleaned while still uncured using a commercial solvent such as xylol, tofuol or methyl ethyl ketone.
Observe proper precautionswhen using flammable solvents.
Precautions: CAUTION! May cause eye irritation. Avoid eye contact Avoid prolonged or repeated skin contact. KEEP OUT OF REACH OF CHILDREN.
During cure, this sealant evolves methanol. Provide adequate ventilation to prevent methanolvapors above 200 ppm. If airborne concentration exceeds 200 ppm, use air-supplied or self-contained breathing apparatus.

RE: Inspection of Drywell Concrete Floor Pursuant to the request to inspect the concrete adjacent to the drywell shell, MSDE and Projects (EdTaintor) conducted an inspection on 5/1/01at 0800 hrs. Some randomly tocated radial cracks were observed which extended about 8 inches inward. These are considered to be normal shrinkage cracks which occured after initial placement of the concrete. These are sound, tight cracks without structural significance.
The general floor area within a foot of the seal location is in good condition which is consistent with the previous maintanance rule walkdown. Plant structures inclusive of concrete are periodically inspected and controlled in accordance with Maintenance Rule (10CFR60.65) and VY PP-7030. There are no signs of efflorescence, no degradation of the concrete surface and no signs of structural cracking or rust staining. Based on these observations, and review of the previous Maintenence Rule Inspection Report, MSDE finds that the condition of the slab, adjacent to the seal location is satisfactory.
As stated in the Scoping Memo (VYM 2000/016)the intent of the inspection was to examine the area adjacent to the seal for open cracks to ensure that moisture will not wick into the seal area. This memo should be within the job order file and it is suggested that it be reviewed, as it provides a comprehensive overview of the entire project and its intent.
There is one area near the A recirc pump where the crack runs parallel to the shell for about 12 inches, adjacent to the seal keyway. The cause of this crack is unknown, but is consistent with impact damage. The possibility of spalling the area during paint removal activities is recognized. The accepted solution if required is contact the Maint Rule Coordinator and to repair the spalled area with Embeco 885 grout.
Please feel free to call on us again for questions or concerns regarding this project.

Inspection of Drywell Concrete Floor This message is to document the VYlCE inspection of the concrete floor in the Drywell at El.238 as required by Minor Mod 00-010, D w e l l Moisture Barrier Replacement, step 7.3. i made the inspection this shift and found cracks in the existing coating on the floor that run from the edge of the floor in a radial direction towards the center of the drywell.
Because the existing coating is in place on the concrete floor, the extent of cracking in the concrete {if any) is indeterminate. The scope of this Minor Mod does not include removal of the existing coating on the concrete floor to inspect the concrete.

FW:Drywell Seal Surface Prep
Subject:
Drywell Seal Surface Prep The required prep to an SP-10 for the area below the seal (eg, below the overall concrete urface elevation and within the notchichampheradjacent to the steel liner) was achieved by the night crew using a rust grade D VIS-1. Therefore, this issue has been resolved for this project since the entire surface has now been determinedto meet the "Near W hite Blast Cleaning" criteria.
The profile of the rust grade D area has a maximum profile of 5.5 mils which is above the specified limit of 1-3 mils. The majority of this area is contained within the seal and will not be exposed to the environment. This area also receives an initial coat of CZ-11 which provides cathodic protection.
It is important that the high peaks within the rust grade D areas receive a complete coat of CZ-11.
These areas will need an increased mil thickness to provide coverage of the steel. Therefore the maximum mil thickness of the CZ-11 in these areas is 6 mils DFT the maximum allowed per Carboline. Remember, excess millage leads to mudcracking, which will cause rework.
Also, the general criteria for the rust grade C areas is still 3 mils D n , recognizingthat some overspray from D to C grades will be inevitable.
Please discuss these changes with QC and the painters to resolve any concerns. Notify me when the mmod is ready for signatures.
I trust that this resolves the open items to date. l e t me know if we need any further refinements.

. JOB SAFETY ANALYSIS JSA No. 22.25 copy Rev. I DRYWELL MOiSTURE BARRIER REPAIR WO# 00-01840-000 M M # 2000-010 Purpose The objective of this project is to replace the drywell to containment shell floor seal at elevation 238' to limit moisture from entering into the space between the shelf and the reinforced concrete floor. The Vermont Yankee drywell shelf has a limited corrosion allowance for the steel shell and therefore maintaining a protective coating and effective seal in this region is required.
Discussion (Attach JSA Check Sheet)
The first phase of the project is lead paint removal and surface prep of the drywell liner plate. This will involve prepping a 6" wide band around the perimeter of t h e 238' level of the drywel!. Existing lead paint will be removed and the surface prepped using a vacuum blasting system that has been effectively demonstrated at the NPS fab shop. These units operate as closed recycling, abrasive blasting systems. Containment occurs at the point of blasting, with the blasthead creating a "containment" that is linked to a vacuum return. Most of the abrasive and dust are collected by this unit. An additional HEPA hose will be held in close proximity to he blasthead to ensure all dust and grit are collected and the lead paint dust does not become airborne. Rotary peening tools and/or needle guns attached to a HEPA vacuum may also be used in some areas. The additional HEPA hose will be used here as well.
The second phase of the project is to apply a coat of zinc primer to the 6" wide band around the perimeter of the 238' level of the drywell that was prepped in the previous step. The surface area to be primed (70 ft.') is roughly equal to both sides of a 4' x 8' sheet of plywood. Application will be by spraying.
Solvent vapors from the primer are heavier than air, so they will primarily remain in the lower level of the drywell, where exhaust ventilation will be established. Cure time is one hour at 50% humidity, slightly longer at less than 50% humidity. Application of the pri-merwill occur during the night shift. The plan is to apply the primer as close as possible to the beginning of the night shift and allow curing overnight when there is little activity on the 238 level of the drywell.
i I Ventilation will be established in one of two manners. The first option will utiIizkge installed plant ventilation equipment. Vacuum breakers VI 6-19A and V?6-19D wil[ be fixed in the open position, creating a flow path from the Drywelf to the Torus. RTF-5 will be aligned to the Torus via vabe V36-19-7. This will establish a ventilation flow path from the Drywell to the Torus and exhausting to the Reactor Building ventilation system through RTF-5. The second option for ventifafionwif/ ufilize carbon filter elements in fhe dedicated 5k HEPA units. This will provide a localized ventilation pafh with increased air flow, Drywell ventilation will remain operable during either of thiese activityjes .
Welding and burning activities will be controlled during painting. This wilI be based on air samples by Safety Standard 102,R l Attachment 5.3 Page 1 of 3
RP and evaluations by the Shift Engineer. The air on both the 238 and 252 levels will be monitored closely t o ensure the vapors are being exhausted properly. Calculations indicate that exposure levels for this application process will be less than 50% of the allowable exposure limits stated in the MSDS for this material. Continuous communication with the plant is planned to reinforce that slight odors are to be expected but are not hazardous based on monitoring and by limits set by MSDS and vendor information.
Dow Coming 795 Silicone Building Sealant wit1 then be applied to the enire perimeter of the lower level of the drywell where the concrete floor contacts the steel shell. The length of this joint is 740 ft.
and the size of the groove to be filled with sealant {after grouting) is 1/21) deep x I1/2n wide. The total voIume of sealant that will be used to fill the groove is a little more than 5 gallons. The exposed surface area of the top of the groove is about 18 sq. fl., or about 1.0% of the surface area of the 238 elevation floor.
The sealant evolves methanol while curing. Adequate ventilation shall be provided to prevent methanol vapors from exceeding 200 ppm. Evaluation of this application process has determined that this process will generate less than 60% of the allowable exposure limits defined by the MSDS.
To further ensure personnel safety, atmospheric monitoring will be conducted during the application process and the initial curing.phase. The same ventilation path described previously will be utilized.
Drywell ventilation will remain operable during this activity.
The sealant will be applied on night shift and will be allowed to cure overnight. 70% of the solvent is given off during initial curing (about 6 to 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />). Based on the amount of sealant required, it is anticipated that there will not be any adverse effects from these vapors after the initial overnight cure.
Welding and burning activities wit1 be prohibited on the 238 elevation during the application of the sealant and the first night of curing.
The MSDS for the product describes it as having a slight odor. This implies that there should not be any annoyance factor associated with the product. Continuous communication with the plant is planned to reinforce that slight odors are to be expected but are not hazardous based on monitoring and by limits set by MSDS and vendor information.
The final phase of the project is to apply a coat of epoxy topcoat to the 6 wide band around the perimeter of the 238 IeveI of the dryweil that was primered in phase 2 (about 70 ft.).
Solvent vapors from the epoxy topcoat are heavier than air, so they will primarily remain in the lower level of the drywell, where exhaust ventilation has already been established. Cure time is 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> at 50% humidity and 75 F, slightly longer at lower temperatures. The plan is to apply the epoxy topcoat as close as possible to the beginning of the night shift and allow curing overnight when there is little activity on the 238 level ofthe drywell. Welding and burning activities will be controlled during painting.
The air on both the 238 and 252 levels will be monitored closely to ensure the vapors are being exhausted properly, Drywell ventilation will remain operable during this activity.

Background
In the Response to Generic Letter 98-04 (reference 2) Vermont Yankee states that Service Level 1 coatings used inside primary containment wilI meet the intent of ANSI N101.2, N101.4 and Reg Guide 1.54. Proposed revision 1 to Reg Guide 1.54 issued as Draft Reg Guide DG-1076 endorses the use of ASTM D-5144-97 (and others) for guidance on practice and programs for protective coatings used within nucIear power plants. This draft guidance was issued because the referenced ANSI Standards were withdrawn in 1988 and the responsibility was transferred to the American Society for Testing and Materials (ASTM).
Draft Reg Guide DG-1076endorses the EPRI Guideline on Nuclear Safety Related Coatings (reference 1) for guidance on the selection, application and maintenance of safety related components. Vermont Yankee committed to evaluate the EPRI guideline and to implement, as 1
appropriate, into our procedures for Service Level 1coatings used within primary containment (reference 2). To date, Vermont Yankee has not developed any plant-specific Service Level 1 coatings procedures. Therefore, in order to support the drywell seal project, Service Level 1 coating procedures are required.
The Drywell Seal Project (reference 4) provides for localized protective coating replacement at elevation 238 within the drywell. The coating in this area has been determined to be Nuclear Service Level 1, and based on current licensing commitments, needs to be installed in accordance with approved plant procedures. The current state of protective coating procedural development for Vermont Yankee is in the planning stages. In order to implement the project scope as defined, arid in a timely manner, necessitates the development of a project specific coating plan in accordance with the requisite commitments made relative to Generic Letter 98-04.
The EPRI document accepted as guidance for the installation of protective coatings has been used for the development of the Coating Inspection Plan and qualification of the protective coating system. This plan and qualification ensures that the appIied coatings will meet the intent of the referenced documentation. The coating installation will be implemented via Mmor Modification 2000-10 during the next refueling outage.
A three phase development of the project specific coating plan is identified on the engineering schedule. The first phase is the documentation of the Structural Steel Painting Council (SSPC) and ASTM criteria as identified in EPRI Guideline. This coating inspection plan has been completed. The second phase involves the identification of the recommended Service Level 1 coating system to be utilized and verification of the coating qualification in accordance with the EPRI guidelines. The third and final phase is the review of existing NPS procedures and possibly the development of procedures specific to this project. As stated in the scope memo (reference 4) Projects Engineering is responsible for the development of the installation instructions, or more specifically, submittal of NPS coating procedures for engineering review and comment.
Based on Mechanical / Structural reviews performed to date, the NPS personnel qualification procedure, PP- 1001is workable contingent upon satisfactory resolution of comments submitted to NPS. The NPS painting and protective coating appIication procedure, PP-0958P, is not acceptable for the project. The procedure in its current form is limited to maintenance, small touch-ups and repairs. The boiler plate of references covers a multitude of surface preparation techniques which are not employed within the actual body of the implementation section of the procedure. Also, there is an existing conflict within the procedure for surface preparation when compared to SSPC requirements. Several of the boiler plate items are used in the surface preparation and application of the selected coating system and need to be procedurally addressed. This procedure will either need a significant rework to meet SSPC requirements or will need to be broken up into multiple procedures so as not to address all aspects of surface preparation, application and coating specification for the drywell seal project with a single procedure (reference 9).
2
A coating system that satisfies design requirements in terms of performance based testing and compatability with the existing substrate is an inorganic zinc primer with an epoxy topcoat.
The inorganic zinc provides excellent corrosion resistance, weathers well and is often used in tanks.Inorganic zinc was the origind coating used in containment and has a well proven performance record. The use of this primer, with the recommended surface preparation will provide the required corrosion protection to this area of the drywell. This will satisfy one of the primary objectives of the project, mitigation of the observed corrosion at the 238 in the drywell interior region. Inorganic zinc provides a sacrificial anodic coating which assures that coating degradation in the future will not be coupled with fast corrosion of the substrate due to the inhibitor properties of the zinc. The epoxy topcoat will provide excellent abrasion resistance, decontarninability, and is a surface tolerant coating. The epoxy will also prevent damage to the zinc primer. Carboline products, Carbo Zinc 11 SG and 890 epoxy has been selected as the protective coating system for this project. These products have been previously qualified and employed at Vermont Yankee for the Torus Painting Project, EDCR 97-423.
The qualification
/-----
A=
The standards used to define DBA N101.2 and ASTM D3911. The s t a n c i a r e d e temperature, pressure, radiation and duration. ASTM D3911 requires that samples be irradiated per ASTM D4082 at an integrated dose rate of lxlOE9 rads at a rate of 1MRlhr. No checking, cracking, peeIing, flaking, delamination or blistering is permitted. The Carboline system has been qualified to both of these standards and has been documented as qualified for DBA conditions.
Technical Evaluation of New Coating System Suppression Chamber and Vent Header, Rev. 2 (reference 6),evaluates and presents the results of DBA testing for Carboline products. Carbo Zinc 11, inorganic zinc primer ,applied at a dry film thickness of 2.5 to 6.0mils, and exposed to test conditions of 340 degrees F, 70 psig and pre-irradiated to 1E9 rads, produced no coating defects or laminations. These conditions exceed that of a loss-of-coolant &OCA) event. A preliminary GE report on Containment System Response Analysis (reference 7) has indicated that the maximum post-accident drywell temperature is currently 336.1 degrees, however the peak drywell shell temperature is 272.1 degrees. The drywell shell maximum design temperature is 281 degrees F (reference 7, reference 8). The FSAR,figure 14.6-5 rev 2, identifies maximum LOCA pressure for the drywell as 30 psig, significantly less than the test pressure. VY DES Memo REG 98-029 identifies the radiation exposure for 40 years plus one hour of accident operation at 6E7rads. This document also identifies the radiation exposure for 40 years of operation plus one year of accident operation at 7E8 rads. The Carbo Zinc 11 primer is documented to remain intact at radiation levels greater than those expected for a Vermont Yankee design base accident.
Carboline 890 epoxy, applied over a pre-existing Carbo Zinc 11 primer has undergone DBA testing with a pre-irradiated dose of 2E8 rads. Test temperatures were 320 degrees, 48 degrees less than the postulated peak drywell shell temperature. Test pressure was 50 psig. Surface preparation for the test sample was SSPC-SP-2, Hand Tool Cleaning, which is considerably less stringent than the SSPC-SP-6, Commercial Blast Cleaning, specified for the 238 drywell area. This test was performed to evaluate the integrity of Carboline 890 as a maintenance 3
repair to a previously painted surface with marginal surface preparation. The test documents that the coating did not exhibit defects or delaminations.
The Carboline Level 1Nuclear Coating System test data documents that the system, proposed for use in Vermont Yankees drywell, when subjected to even higher dose rates (1E9), meets the requirements of ANSI N 101.2- 1972 and ASTM D 391 1.Temperature levels for the test were 28 degrees higher than expected maximum post-accident drywen shell temperature of 272 degrees. The test temperatures indicated on the test report were at 300 degrees F for the eleven day duration with a pressure of 48 psig. Carbo Zinc 11 has undergone stand alone testing at a temperature of 340 degrees with satisfactory results when applied as..rtmaintenance repair to a poorly profled surface. Elcometer test results for each of the components shows that the inorganic zinc coating has a lower tensile strength. Bond failure of the zinc is not expected since it has been tested to conditions exceeding that of the DBA conditions. Topcoat failure of the epoxy is also not expected since it has a higher tensile strength. Therefore the probability of a bond failure between the primer and substrate and the primer and the topcoat is not expected based on the test data.
ASTM D5144,The Standard Guide for Use of Protective Coatings Standards in Nuclear Power Plants, is endorsed by the EPRI Guidelines. Physical properties of adhesion per ASTM D4541, decontamination per ASTM D 4256, abrasion resistance per ASTM D4060,chemical resistance per ASTM D3912 and flame spread per ASTM E84 have been verified as acceptable.
ASTM D 4541, the Standard Test Method for Pull-Off Strength of Coatings Using Portable Adhesion Testers, provides a method of determining the resistance to a load perpendicular to the coated surface (tensile strength). It determines if the surface will remain in tact at a prescribed force to assess the acceptability of the coating system. The Carboline system is acceptable at 350 psi.
ASTM D 4256, the Standard Test Method for Determination of Decontaminability of Coatings Used in Light-Water Nuclear Power Plants, provides a method for determining the ease of cleaning the coating after a 7 day immersion in a radionuclide soIution. The significance of this test is that it provides a measure of the ease of decontaminating the coated surface. This can result in a reduction in the level of contamination and mitigate exposure to pIant personnel. This test is applicable to the Carboline 890 epoxy topcoat only which exhibited a 99.96%removal. This equates to a decontamination factor (DF)of 250.
ASTM D 4060, Abrasion Resistance of Organic Coatings by the Taber Abraser, qualifies the coating by subjecting it to a rotating motion under abrasive, weighted wheels. Abrasion resistance is calculated as a weight loss of the sample relative to the number of cycles. The Carboline 890 was subjected to 1000 cycles, under lOOOg with a CS-17 wheel. The results of this test is acceptable at 85 mg weight Ioss.
ASTM D 3912, Chemical Resistance of Coatings Used in Light-Water Nuclear Power Plants, is a limited test, as it does not test for a full range of potential chemical exposures. This test was performed for a simulated exposure to a chemical splash, where the solution may evaporate in place. The test is performed by immersing a sample in general service and decontamination solutions for a period of five days and evaluating the results over time.The 4
samples are evaluated for blistering, delamination and peeling. The Carboline system produced acceptable results except for exposure to nitric acid and potassium permanganate.
Neither of these reagents would be expected to be used for any purpose within containment since they are typically laboratory reagents used for metal digestion and as a titrating oxidant.
Therefore, the results of this test are acceptable.
ASTM E 84,Surface burning Characteristics of Building Materials, provides a comparative measure of surface flame spread to that of red oak (=loo)to that of inorganic reinforced cement board (= This (isIa) ,
distance / time based standard. The index for the Carboline system is reported as less than 25. This is the acceptable minimum vaIue as defined by NFPA standards for non-combustible. Individually, the Carbo Zinc has a documented flame spread index of 6. The epoxy topcoat has a flame spread index of 5.
Conclusion The Carboline Level 1 Nuclear Coating System, comprised of Carbo Zinc 11 SG primer and a Carboline 890 epoxy topcoat is an acceptable protective coating for use within the Vermont Yankee drywell steel substrate. This system satisfies the requirements of ASTM D 5144, which supercedes the ANSI standards in effect at the time of original construction. The EPRI Guideline, TR- 109937,has been reviewed and utilized for this application, and satisfies the current Vermont Yankee licensing basis.
The Coating Inspection Plan has been drafted in accordance with the SSPC guidelines contained in SSPC Publication #91-12, Steel Structures Painting Manuals, Volumes 1 and 2, Seventh Edition, and SSPC 97-07, The Inspection of Coatings and Linings. This plan will be utilized as part of Minor Modification 2000-010which implements the coating portion of the drywell seal project.
Procedural development for the application of the coatings and personnel qualification of the coating inspection personnel is currently under development. The combination of an approved Level 1 Nuclear Coating System, Inspection Plan, and qualification of inspection and application personnel will ensure that Vermont Yankee is in compliance with the applicable references and standards as was committed to in BVY 98-147.

Installation of a drywell seal at elevation 238' and perimeter painting of a cicumferential strip approximately 6 c/- inches wide.
Based on a review of the following questions, determine if the proposed activity has the potential to impact safe operation of the facility and requires a 10CFR50..59(a)(2) evaluation. A "YES" answer to any of the questions 2 through 25 requires that a written 10CFR50.59(a)(2) evaluation be perfzrmed. Either evaluation may require an FSAR change in accordance with AP 6036 or a TRM change in accordance with AP 0060. These questions need to be answered based on a review of the activity (i.e., procedure change, Temp. Mod.,
Equivalency Eval., Lineup Deviation, etc.) vs. the requirements of the FSAR or interim FSAR changes, the TRM and Tech. Specs. The originator should provide a response to "NO" answers that are potentially applicable to provide a basis for the conclusion.

"1. Would the activity require a Tech. Spec. change prior to implementation? If "YES" then a Tech. Spec. change must be completed before the activity can commence.
YES @
- 2. Would the activity result in a change that would directly or indirectly render a system, structure, or component ( S S C ) either different in design, or different in function or in method of performing a function (e.g., change manual to automatic, etc.) than that described (written or pictorial) in the FSAR, interim FSAR change or TRM. (Note that pictorial changes that do not effect system design parameters or system operation are not considered to satisfy this I
criterion; eg: addition of an instrument isolation valve.) YES @
The seal as described in 5920-233, will be maintained in form, fit and function.
- A yes response to the question WAPF 6002.02 (Sample) indicates that the activity cannot be AP 6002 Rev. 7 performed under 50.59. Prior regulator approval is required to perform activities which require a T.S. change.
