NUMBER REVISION, DATE i PAGE i CPSES i JOB 35-1195 CP-CPM 6.12 0 l 7/22/82 3 of 7 3.0 REFLECTIVE INSULATION 3.1 GENERAL INFORMATION 3.1.1 Reflective insulation is a system composed of panels (and support steel as required) to complete an assembly of vessel, pump, or piping insulation. Each panel of a system is permanently marked with an identification mark number for positive assembly location. c 3.1.2 Insulation panels are assemblies of sheet metal, cut and formed, to create outer and inner cases, disks, closures, liners, spacers, handles, and laps (See Attachments 1, 2, and 3). n 3.1.3 - The insulation may be secured with bands, buckles, screws, turn a buttons, bended laps, or buckled straps (See Attachments 1 and 3). 3.1.4 Where stainless steel screws and lockwashers are used for fastening they have been shipped in separate sacks fastened to the inside of each shipping crate. 3.1.5 The support steel is made up of angles, straps, sheet steel, and rods. It is either welded or bolted together and is made from carbon or stainless steel, depending on specification requirements. 3.1.6 All _ bolts, nuts, washers, screws, clips, seals, etc., are supplied by the vendor unless noted on the applicable drawing. 3.2 DEFINITION OF TEPJ45 ASSOCIATED WITH REFLECTIVE INSULATION 3.2.1 Convection seals - metallic seals used to reduce convection losses. ~ 3.2.2 End disk - structural members placed at the end of a unit of insu-lation and fastened to both the inner and outer cases. Their pri-mary purpose is to increase the structural integrity of the unit.- 3.2.3 Gap - an opening in the insulation unit proper, or an opening between adjacent units which is a potential source of heat loss due to con-vection. 3.2.4 Inner case (I.C.) - the innermost sheet of the unit of insulation (closest to the hot surface). It usually performs structural ij functions in addition to its thermal functions. I i t +

BROWN & ROOT, INC. PROCEDURE EFFECTIVE CPSES NUMBER REVISION DATE PAGE i JOB 35-1195 CP-CPM 6.12 0 7/22/82 4 of 7 3.2.5 Laps - metallic strips that overlap a longitudinal'or circumferential, joint in the insulation to restrict internal conve.ction losses and to shed external falling water. They may be integral with one piece of the outer case or separate strips secured to it. 3.2.6 Outer case (0.C.) - the outermost sheet of the unit of insulation (farthest from the hot surface). It usually performs structural functions in addition to its thermal functions. 3.2.7 Penetrations - openings in a unit of insulation from the hot surface through to the cold surface. 3.2.8 Reflective liners - the reflective sheets interposed between the inner and outer cases to reflect radiant energy, to minimize emission of radiant energy, and to restrict internal convection. 3.2.9 Rework - the process of physically modifying a unit of insulation to alter its form and/or function. 3.2.10 Section of insulation - a single structurally independent assembly of inner case, outer case, reflective liners, and end supports (if required). 3.2.11 Slab off - the result of cutting away a portion of the outer case and liners, resulting in a reduced thickness of insulation, the purpose of which is to clear a physical interference with the insulation. 3.2.12 Thickness - the distance from the inner case to the outer case. 1 3.2.13 Unit of insulation - two or more sections of insulation which when 3 fastened together form one unit of insulation. 3.3 BASIC GUIDELINES 3.3.1 Pop rivets are stainless steel and are sapplied by Mirror. 1j 3.1. 2 The spot-welder used should be 7.5 KVA post type. NOTE: Pop rivets and spot-welds may be used interchangeably, as desired, on a one for one basis. 1 e CP-CPM 6.12 Rev. O DCN #4 4/25/84 Sheet 2 of 5 .i ---.n-..~- .. ~.. ...ep.

When a modification if made which results in a physical separation of the inner and outer case (I.C. and 0.C.) the I.C. and 0.C. should be re-attached to each other via the end disk and/or split line bracket as appropriate. 3.3.4 When modifications are made which require the use of rework material l (i.e., inner case, outer case, liner material, walkplate, etc.) the rework material should be the same gauge and material type (i.e., 304 S.S.), as the original insulation. 3.3.5 When modifications are made which change the location of buckles and l keepe rs, relocation of the buckle must be made first on the section having the integral lap. With the adjustment section of insulation held in place and the buckle latch at 90* from the closed position, the keeper can.be located and pop-riveted in place. (See Attach-j ment 4). l 3.3.6 Where screws are used for securing piping and vessel insulation units and modifications to the units eliminate the existing hole location, new clearance holes should be made in the lap adjacent to the modifi-cation and a #30 drill hole made for the screw. Screws should be j inserted with star washers and tightened securely to prevent loosening under vibration. c. [ 3.3.7 All gaps which may result due to rework of the insulation shall be I covered with laps or seal plates. 3.3.8 Liner spacing shall be maintained as close to the original spacing l as practical (i.e., 33 inch !.03 inch centerline to centerline of liners). 3.3.9 Material thickness (especially liners) shall be the same as used on j the original unit. 3.3.10 Cleanliness of rework materials shall be maintained at all times. 3.3.11 Reworking the insulation should be done in a workmanlike manner with l cuts clean, neat, and flashed to restrict air flow in or out of the insulation. l 3.3.12 Accidental dents occurring ~ in the outer case during rework should be kept to a minimum. t I 3.3.13 Rework insulation units shall be clean of all visible contaminants l before being installed. 3.3.14 There should he no deviation from Mirror standard hardware (i.e., buckles and handles should be Mirror Original Equipment.)

If a unit is subdivided into 2 or more sections, the same identification numbers shall be used on all sections. 3.4 HANDLING 3.4.1 When handling individual insulation sections, personnel shall wear clean gloves in order to minimize personal cuts and gross contamir.ation by skin oils. Care shall be exercised not to bend or dent the panel edges or flat surfaces. 9 3.4.2 Each individual section of reflective insulation and support steel is permanently marked, providing positive identification in the field for proper erection sequence. 3.5 INSTAI ~.ATION The actual installation of reflective insulation shall be performed in accordance with Operation Travelers (per CP-CPM 6.3), which will either reference or have attached vendor supplied manuals, and/or approved vendor installation drawings. 3.6 REWORK AND MODIFICATION Rework or modification of insulation which has been accepted by QC, shall be accomplished af ter an IRN has been prepared in accordance with CPM 6.10. This applies to QC inspections documented on travelers which are already in the records vault or on QC checklists. e 3.7.1 Panel Dents / Holes Field Repair 4 a. Where accidental denting / holes in the panel outer cases or inner 4 cases has occurred, it may be possible to repair them in the field without affecting performance. Attachment 5, 6, and 7 1 show the methods of making such repairs. j b. Dents may also be removed by drilling a hole in the outer case j and installing a pop rivet with to pull out the dent. l The pap rivet shall he cut of f af ter the dent has been pulled. c. Where accidental minor denting of the stainless steel end disks has occurred, this condition may be corrected through careful use of a hand seamer (straightener) and/or mallet. d. Where accidental minor denting or bending of the exposed flanged edges of the inner reflective sheets has occurred, these may be straighened through careful use of a hand seamer. L CP-CPM 6.12 Rev.

Equipment may be preliminarily aligned and still be considered " Stored-in-Place". 3.0 GENERAL o 3.1 The storage environmental conditions for itens are divided into five types, (as type A, B, C, D, E, and exemplified in Appendix A). These types are divided with respect to protective measures to b prevent damage,. deterioration or contamination of the items and are based upon the important physical characteristics and not upon the important functional characteristic of the item. It should be recognized, however, that within the' scope of each type.. there may be a range of controls and that the detailed requirements of an iten are dependent on the importance of the item to safety or reliability. For example, even though a reactor vessel and structural steel may be classified as type 0, the degree of protection and control over the reactor vessel should exceed thot of the structural steel. Any package unit or assembly made up of itens of different types, shall be classified to the highest type designated for any of the respective parts. i-If the unit is disassembled, a type shall be indicated for each part. The Equipment Maintenance Record (Attachnent 1) shall specify L the type of storage required. Itans shall be stored as specified P unless a higher type storage is used. The following attributes, as applicable, shall be observed and implenented in the storage j areas: 1 3.1.1 Cleanliness and good housekeeping practices shall be enforced at all times in the storage areas. The storage areas shall be cleaned as required to avoid the accumulation of water, trash, dirt, and discarded packaging materials. 3.1.2 Measures shall be taken to prevent the entrance of rodents and 2 other animals into indoor storage areas or equipment to mini-i mize possible contamination and mechanical damage to stored jl material. Also, measures shall be taken to control entrance of insects into sensitive itens such as instrumentation.

Storage of pieces of equipment and material in the immediate plant construction area should be limited to that necessary. o Itans taken from storage shall be either installed or " stored-in-pl ace". Items taken from storage shall be maintained to conform with storage and maintenance requirements previously established unless:otherwise specified on the Equipment Maintenance Record (EMR). Itams shall merit additional protection if construction work threat-ening the integrity of equipment is in progress. For example: if ~ concrete or structural work is in progress in the immediate vicinity, a wood or polypropylene shelter shall be erected around the item if necessary to protect it from damage or contamination. NOTE: The above paragraph must be interpreted in terms of its intent, and that is to protect permanent plant equipment from damage. As a matter of construction convenience, it is permissible to use permanent plant installations such as pipe, pipe hangers, tray hangers, etc., to support work platforms or scaffolds, or other construction work impro-visations provided that such construction activity does not damage the permanent installation and does not violate job-site safety rules. However, rigging from supports shall be avoided unless authorized in writing by Engineering. 3.7 Equipment which contains desiccant shall have a sign affixed to the side of the equipment indicating the quantity and location of the desiccant. Humidity indicator shall be used for monitoring the humidity. Upon a humidity reading of 50% or greater, the desiccant shall be replaced. 3.8 Each vessel / equipment fabricated under ASME Code, lined vessels and stainless steel vessels shall be provided with warning signs .i which read " WARNING - DO NOT BURN, WELD, CHIP, GRIND, OR ALLOW ARC STRIKES ON THIS VESSEL". l =. =..--. - -. - = --

This procedure for the original issue of a EMR applies to any subsequent revisions. 4.5 The EMR's with original review signatures shall be considered as the " controlled" instructions for implementation. The appropriate department implementing the instructions is responsible for con-trolli g and maintaling the EMR's. 4.6 The record custodian, as designated by the craft superintendent, shall maintain a log of the EMR and pertinent revisions. The record custodian is responsible fbr issuance and retrieval of the EMR's to and from the maintenange personnel. (The EMR file will normally be sorted by tag number fbr equipment, serial number fior "Q" valves, and generic nsaber flor "Non-Q" valves.) Alternatively, other methods may be used which provide ready retrievability. When other methods are used, a log should be maintained for cross reference to equipment or serial number as applicable. 4.7 Unless all instructions have been. rewritten on the EMR, a controlled copy of this procedure and the original or a copy of EMR shall be taken to the storage area and used as maintenance criteria. The original ENR shall be signed by craft personnel, foreman, and QC as a verification of the maintenance performed. If any of the maintenance acitivities being performed are unacceptable and/or i the item integrity is revealed to be unacceptable, QC shall make a note in the " Remarks" coltan on the EMR to that effect. Upon completion and acceptance of the corrective action, QC shall make closing note against the previously noted discrepancy in the i~ " Remark-s" coltaan. 1 For "Non-Q" items, any problems with maintenance and/or unaccep-table item integrity shall be referred to Engineering for resolution. 4.8 Upon termination of B&R maintenance responsibility, the completed "Non-Q" item EMR's shall be submitted to " BOP Doctamentation Group" and "Q" item EMR's shall be submitte'd to the Permanent Plant Records Vault. l NOIE: Supplements to this procedure (MEI-10-Series) which have been generated as a part of the storage and main-tenance program shall be utilized as required by the previous revisions of this procedure, unless the MEI's have been converted into EMR's and MEI's have been recalled from Doctament Control Center. 6/7/84 Sheet 2 of 3 MCP-10 Rev. 7 DCN #6 177.- m ',xA w ( ~ ---e.*

1.1 PURPOSE H This procedure details the methods to be used for cutting and welding activities on weld joints on systems which have been flushed or hydroed, or that have been designated to be worked in accordance with " clean weld" fabrication methods. 2.0 GENERAL 2.1 It shall be the responsibility of TUGC0 Startup to designate on the applicable Startup Work Authorization (SWA) where " clean weld" fabri-l cation methods are to be used, and to designate which one is to be used. If SWA's are issued for systems which have been flushed or o h hydroed and the SWA does not specify " clean weld" methods are to be used, the SWA shall be returned to Startup for re-evaluation. The ,d SWA shall not be worked unless it is specified on the SWA whether or not clean weld methods are required. The Pipe Superintendent shall l return all previously prepared weld data cards to Welding Engineering l l

These weld data cards shall be modified to incoporate the additional hold points and instructions necessary to control the activity. (See Attachment 1). 2.2 All fabrication and documentation shall be in accordance with the requirements of CPM 6.9 except for specific deviations required by this procedure. 3.0 WELDING ACTIVITIES ON WELDS WHICH CANNOT BE ISOLATED FROM THE BALANCE OF THE SYSTEM 3.1 WELD JOINT REMOVAL 3.1.1 Weld metal shall be removed by grinding to a blue metal condition with care being taken not to grind through the root of the joint. The remaining weld metal shall be removed utilizing a metal saw blade. Cutting shall be accomplished in one direction only with th blade being cleaned of metal filings after each stroke. Once an i opening through the root has been established, the. direction of cutting shall be from the inside out. NOTE: Small diameter pipe may be ground to a blue metal condition q nU and then broken instead of cutting. ~ U 3.1.2 Upon completion of the cut, the ID of the sections of piping remaining in the line shall be inspected for any loose dirt or filings in the area of the cut. Any such materials shall be removed using clean rags or a vacuum cleaner. 3.1.3 Prior to any further work, a purge dam seal of similar construction shall be placed on the ID of the pipe or component being worked in order to contain any grinding dust or debris resulting fr'om joint preparation. This seal shall be left in place until both sections of the weld joint are prepared and ready for joint fit up. Prior to removal, the area of the accessible side of the seal shall be vacuumed and wiped down with an approved solvent. NOTE: As no further grinding will be permitted after seal removal, a mock joint fitup should be made before the seal is removed, to insure that additional grinding will not be required to l facilitate proper fit up. l 3.2 JOINT FIT UP q I Joint fit up shall be made utilizing a consumable insert and shall conform to the fit up tolerances of 6.90. Tack welds shall be partial penetration which will be remelted during the welding of the root pass. These tack welds require no grinding. eg. '"****~~***"*P* ++

NUMBER REVISION DATE PAGE 9 CPSES () l ~ JOB 35-1195 i CI-CPM 6.9E-2 1 l11/22/82 3 of 4 NOTE: In those cases where the weld joint is made up of materials which prohibit the use of a consumable insert, an open butt joint configuration may be used provided "C" lugs are employed for joint fit up in lieu of tack welds in the weld joint. t' 3.3 REPAIRS 3.3.1 Through the root excavation shall be avoided. Repairs to the root portion of a " clean weld" shall be accomplished by grinding to within approximately 1/16" of the ID of the root, where this depth is nec-essary, and refusing (remelting) the area of concern. 3.3.2 Such repairs shall be made under the direction of a Welding Engi-neering Technician in accordance with an operational sequence con-tained on the applicable Repair Process Sheet approved by the PWE. 1 (See Attachment 2). 3.3.3 A UT thickness measurement shall be performed on the area to be repaired prior to any excavation to determine the maximum depth of excavation. 3.3.4 Exceptions to the above shall be made only with the approval of the Q Project Welding Engineer and the responsible TUGC0 Startup Engineer i! on a case by case basis, p 3.3.5 Repairs to other than the root portion of the weld may be made in accordance with normal repair procedures. I: 4.0 WELDING ACTIVITIES ON WELDS WHICH CAN BE ISOLATED FROM THE BALANCE OF THE SYSTEM 4.1 ALTERNATIVES TO PARAGRAPH 3.0 4.1.1 The requirements of Paragraph 3.0 need not be met when system clean-liness can be otherwise maintained. Specific examples are provided below. However, other options are permissible provided they are clearly provided on the SWA by the responsible STE. l 4.1.2 Examples of welding activities which can be isolated from the balance of the system inicude: 4.1.2.1 Removal of a flanged spool from the system. When a flanged spool can be removed from the system, only the removed spool need be cleaned. j f The STE shall verify cleanliness in accordance with Paragraph 5.0 j prior to reinstallation of the spool. 4.1.2.2 Daming h Daming a portion of the system may be used if it prevents contamina-tion of other parts of the system.

When equipment or valves are disassembled to permit the daming, care shall be exercised to ensure that dams are placed such that items such as bearings and machined surfaces are pro-tected, or that particles are not permitted to accumulate in crevices which cannot be subseouently cleaned. 4.1.2.3 Horizontal Piping The requirements of Paragraph 3.0 need not be followed for hori-zontal piping runs 10" NPS and greater provided: 1. There is no likelihood of contamination of the balance of the system. For example, a pipe weld to an elbow connected to a vertical piping run should be worked in accordance with Para-graph 3.0 because there is a good chance the balance of the system will be contaminated if Paragraph 3.0 is not complied with. 2. The internal surface of the piping is readily accessible for cleaning and inspection after the work is performed. 5.0 STE VERIFICATION 5.1 Upon completion of the work and final cleaning, the STE shall be notified and shall perform a cleanliness inspection of the affected item prior to reassembly. The 'STE shall be presented the WDC and indicate his acceptance of the clean condition by signing the WDC. a 1 h 't 1 O = 4 L A y -? ,_,m,.. y

-_;---------=------ l CP-SAP-24 Revision 1 p Page 17 of 18 O ^"Ac""""' o Guidelines for Maintaining Required Cleanliness Level l l Prerequisite Cleenliness 1. Housekeeping - Cleanup of the araa surrounding the work activity will reduce the possibility of introducing foreign matter into an open system or component. 2. Containments - Use of containments built about the system opening or the immediate work area vill reduce the possibility of introducing foreign matter into an open system or components. Containments will 4 also reduce the area surrounding the work activity to be cleanliness controlled. 3. Dans/ Plugs - Plugs, caps, covers, dans or other suitable closure devices should be utilized to prevent the introduction of foreign matter into open pipes, vessels, tanks or duct during work activities. This is particularly important where foreign material entering an open system will be difficult to retrieve. Use of these devices will also reduce the area to be cleaned during in-progress or post-work clean-up. When internal closure devices such as pipe plugs are used, they should be installed as soon as the system is opened and remain in place throughout the work activity. When external closure devices such as covers are used they should remain in place at all times except when access to internals is required. 4. Special Requirements - Additional prerequisite cleanliness requirements d may include: a. Specification of cleaning materials to be available prior to the initiation of work. b. Prohibition of certain materials, tools, solvents, etc., which may degrade system cleanliness, damage system materials or be exceptionally difficult to remove upon completion of work. c. The removal or covering of certain materials (such as pipe insulation) within a selected distance of the system opening to l reduce the possibility of introducing foreign matter into the system interior. In-Progress Cleaning In-progress cleaning methods are similar to those utilized for final l cleaning (e.g., vacuuming, wiping, brushing, solvent cleaning, etc.) except that final cleanliness requirements need not be met. The work area should be kept clean and free of accumulations of foreign matter which could be () introduced into the open system interior.

7 I CP-SAP-24 Revision 1 Page 18 of 18 {} ATTACHMENT D (Cont'd) thap foreign matter will be extremely difficult to remove from system interiors, periodic cleaning of the exposed interior surfaces should be conducted. When in-progress cleaning is specified at critical points of a work activity, hold points or inspections should be specified prior to continuing the work. Final Cleaning Final cleaning met..ods include: 1. Mechanical cleaning by grinding, brushing, vacuuming or similar methods to remove debris, foreign matter, loose soil, unacceptable rust, weld splatter or slag, etc. Material compatibility requirements (e.g., grinding and brushing tools used on nonstainless steel materials shall be used on stainless steel) shall be observed. Exhaust from vacuum cleaners shall be directed away from the work area. 2. Hand cleaning by brushing or wiping. Stiff bristle', nonshredding brushes shall be used. Wiping shall be done after all loose surface contamination has been removed. Clean, lint-free cloths shall be used. Wiping cloths should be changed frequently to avoid redeposit of contaminants. Cloths saturated with an' approved solvent may be used () for degressing. Surfaces shall be thoroughly driediafter solvent cleaning. 3. Flushing may be utilized for' cleaning or for proof of cleanliness after work. In general, however, flushing should be avoided as a cleaning method unless it can be restricted to the work area!since flushing may sweep ;ontaminants into undisturbed portions of the! system. Use of flushing will also result in having to verify that the entire flushed portionofthesystemhasreachedthedesiredfinallcleanlinesslevel rathat than just the portion of the system which was affected by the work activity. s b t 4 d
