In cases where the material ID is not visible, then the QCI shall annotate Quality Engineering Systems (QES) in the space provided. Upon final review of the snubber installation documetation, QES shall verify material identification from I previous hanger installation documentation. 5.4 MODIFICATION OF NPSI REAR BRACKETS When the snubber interferes with the rear bracket, the rear brackets for 35 and 100 snubbers may be modified in accordance with Attachment 11. Modification may be by themal means or machining. If thermal cutting is used, the cut edges shall be smoothened by machining. In either case, the pin shall be removed prior to the modification. 5.5 MODIFICATION OF FORWARD BRACKETS FOR SNUBBER SIZES 35 AND 100 Modification of forward brackets for 35 and 100 snubbers shall be done in accordance with Attachment 12. 1 5.6 MODIFICATION OF SNUBBER TRANSITION KITS (GENERAL) Shortening or lengthening of snubber transition kits to a length that will render snubber pin to pin dimensions outside maximum lengths specified in Attachment 22 must be approved by Engineering by a design change. NOTE 1: If the threaded portion of the eyerod bottoms out in the transition kit before the desired adjustment is acheived, the eyerod may be shortened 4 to achieve the necessary adjustment.

However, enough threads shall remain to allow full thread ungagement in the coupling nut.

NOTE 2: For identification of snubber parts / hardware discussed in this section, see Attachments 1 and 2. a. For both NPSI and ITT Grinnell snubbers the required transition kit length shall be detemined by measuring the pin to pin (C.C) distance in the fi el d. Then subtract the actual cold setting (AC dimension shown on the design drawing) from the existing pin to pin dimension. The difference between these two dimensions is the transition kit length required to maintain the proper cold setting.

BROWN & ROOT, INC. ISSUE CPSES NUMBER REVISION DATE PAGE JOB 35-1195 QI.QAP 11.128A 3 8 of 42 ga g The C.C dimension provided in the Bill of Material or in the sketch are provided for material take off purposes only. The maximum C.C dimensions are provided in Attachment 22 for the different size snubbers. Deviation from these dimensions is not permitted unless authorized by a design change. b. Deviation of more than 1/8" from the specified cold setting (AC dimension shown on the design drawing) is not pennitted unless authorized by a design change. c. If adjustment of an ITT. Fig. 307 snubber is required for installation, the threaded eye rod in the transition kit has an adjustment capability of 131/2". For NPSI SMA snubbers, this adjustment capacity is 1 3/4". Any further adjustment necessary may be made only by modification of the transition kits. d. In order to lengthen the tran:,ition kit, remove the end coupling by grinding or cutting. Snubber sizes 1/4 through 10 have a transition kit mounting plate which must also be removed. e. If the mounting plate is damaged during removal, a new one shall be fabricated from SA 36 or SA 515 Grade 65 steel. f. Replace the pipe portion of the transition kit with a size and grade of pipe selected in accordance with 3 and cut to length necessary to acheive the required pin to pin dimension. g. The length of ITT Fig. 306 snubbers can be adjusted only by the use of shim plates placed behind the rear bracket. NPSI.SMF snubbers can be adjusted either by placing shim plates behind the rear bracket, or by trimming the forward bracket in accordance with Paragraph 4.2.1. h. In those cases where interference problems exist when installing snubbers, they may be mounted 180' ~ (end to end) from the configuration shown on the design drawing. 5.6.1 Mounting of Forward Bracket or Transition Kit into SnubberBody For snubber sizes 35 & 100, screw the transition kit or forward bracket into the internal threads at the base of the snubber until it bottoms against the internal dust cover

For NPSI forward bracket or transition kit, minimun thread engagement is as detailed in Attachment 12. For ITT supplied forward bracket and transition kit, the existing thread length provided on the part is adequate. However, trimming of the thread length for ITT parts is prohibited, unless authorized by Engineering. The thread engagement operation should be completed by hand. If more force is required, remove part and clean all internal and external threads. If after cleaning, thightening is difficult, a strap wrench or other non-marring tool may be used to assist in the tightening P operation. However, the parts shall not be forced. After fully engaging the threads or bottoming, the forward bracket may be unscrewed up to a maxmimum of 1/2 turn to achieve correct orientation of the lugs and pins on each end of the snubber per the pipe support sketch. CAUTION: Do not unscrew more than 1/2 turn. 5.7 INSPECTION CRITERIA The following are inspection requirements when inspecting snubbers: a. To prevent binding within the clamp and/or bracket, snubber shall not be installed with an off-set of more than 5 (five) degrees. b. Verify that flat washers are installed between the spherical bearing and each cl amp hal f. The spacers - may not fit when assembling the rear bracket due to the tolerances. At this time, one or more of the spacers may be deleted. For horizontal brackets or clamps if only one spacer is installed, it should be pl aced on the underside of the spherical bearing when applicable. NOTE: Minor adjustments of the pipe clamp may be required to facilitate snubber installation. c. The clamp pin should be long enough to accomodate l cotter pins on either side, d. Veri fy pinned connections have fully opened cotter pins or split snap rings installed. e. Verify spherical bearings are tightly staked in the attachment ends. f. Verify that exposed threaded surfaces are free of excessive rust or for#pterial. W

Verify that spherical bearings are free of foreign material and gimbals freely in it's race. NOTE: QCI shall document resul ts of cleanliness, and operability of component support parts (i.e., spherical bearings, pins, etc.) on the QC Snubber Checklist in Comments Section. 5.7.1 Snubber Alignment Due to Field Conditions Due to fiel d conditions, it may be necessary to adjust the alignment between the snubber end cap and the mounting hardware (rear bracket or pipe clamp) in order to allow a full 5* misalignment tolerance. All adjustments of thi s type shall be perfomed in accordance wi th the following instructions and witnessed by the QCI. 5.7.1.1 Snubber Sizes 1/4 through 10 - See Attachment 14. 1. Remove attachments from the snubber. 2. Place the snubber in a vertical position on a table-setting on the snubber housing. 3. While keeping a slight downward hand pressure, on the top to avoid linear movement, use retaining ring pliers to free retaining ring. 4. While maintaining a slight downward hand pressure, slowly turn end cap by hand only to desired rotational position. Do not use wrench or other mechanical means. 5. While maintaining hand pressure, replace retaining ring. Expand and contract arrestor slowly through full stroke to determine that repositioning has not damaged internal ~ components.

5. 7.1. 2 Snubber sizes 35 & 100 - See Attachment 15.

1. With the assembly cradled in a bench, remove the three indicator tube mounting screws. Extend the snubber sufficiently to expose the telescoping tube. 2. While the telescoping tube is restrained from rotating, loosen the left hand threaded nut (ring). (Nut has been torqued to 150 2 20 f t. lbs. ) Rotate the end cap to the desired position.

Never interchange NPSI and ITT Grinnel parts or hardware. However, except for the feedwater and mainsteam systems, NPSI and Grinell snubber bodies may be interchanged. I b. It is extremely important that the clamp halves are parallel (see illustration on Attachment 17). Excessive gap at the upper end of the clamp can allow enough space for the spherical bearing to be dislodged from the eye rod end. Flat washers may be installed to fill the gap. c. At no time shall installed snubbers be used as steps or hand.hol ds. NOTE: Pipe clamp assembly infonnation - see Attachment 17 21.

When arc wel ding, do not attach ground to snubber or any part of the snubber which will cause arcing current to pass through snubbers. e. Do not sandblast snubbers. Snubbers are pre-finished with acceptable corrosion protection. f. If sandblasting is to be perfonned on adjacent parts such as unfinished pipe or structure, snubber and bearings on attaching parts must be masked for protection, g. Use care ti align snubber as closely as possible to avoid forces tending to rotate the pipe clamps or induce bending. h. If a snubber is accidentally dropped, check the function by extending and retracting through the full stroke. If there is no evidence of sticking or binding, it may be assumed that no internal damage has occurred. If there is evidence of a mal function, it shall be documented in accordance with Reference 1-D. i 1. To avoid driving spherical bearings free or damaging bearings, use care in inserting pins. Pins should be snug but not tight. Light tapping is allowable. j. Under no circumstances should the snubber housing be twi sted relative to the position indicator tube. This may result in a jammed snubber. 7.0 BASE METAL REPAIR Base metal defects shall be documented in accordance with Reference 1.D. 8.0 TORQUE REQUIREMENTS Torquing shall be witnessed by QC and documented by signature and date on the QC Checklist.

BROWN & ROOT, INC. ISSUE CPSES NUMBER REVISION DATE PAGE JOB 35-1195 QI-QAP.11.1 28A 3 22 of 42 ATTACHMENT 6 1.0 GENERAL 1.1 PURPOSE AND SCOPE This instruction provides the inspection and verification requirements for material or items to be salvaged from Vendor supplied and B&R fabricated snubbers assembl ies, ASME Class 1, 2, and 3 and subsequently used in the fabrication of Class 1, 2 and 3 supports. 2.0 INSTRUCTION 2.1 SALVAGING Never interchange NPSI and ITT Grinnel parts or hardware. However except for the feedwater and mainsteam systems, NPSI and Grinnel snubber bodies may be interchanged. Snubbers and associated hardware may be used on component supports other than those for which they are designated, provided requirements of this instruction are met. When an item is salvaged for use on a support other than the one for which it was designated, the original support mark and serial number; or mark, MIC or heat number; or mark and heat code shall remain distinguishable on the item. If the vendor fabricated snubber assembly with ASME Code 1 plates are salvaged and used on supports other than those for which they are designated, the Code plate (s) shall remain attached to the item if one or more welds remain. When all vendor wlds are removed, the code plate (s) shall be removed, provided the original support number is transferred to the vendor part. Authorization to remove name plates which are shown on the drawing shall be provided by Engineering on the appropriate design change. Construction shall transmit the Code plate (s) to QC by a 3-part memo. QC will subsequently transmit the Code plate (s) to the Owner. For B&R fabricated snubber assemblies that are to be salvaged which contain welds and these welds are to be salvaged, Welding Engineering is responsible for providing the documentation (WDC, WFML, etc.) necessary for QC to accept these welds. This documentation shall become part of the new snubber data package.

B&R fabricated and vendor supplied snubber assemblies that are to be salvaged need not be returned to the warehouse. ASME Field QCI shall reinspect the salvaged items in accordance with Paragraph 2.4. 2.3 SALVAGED MATERIAL RELEASED FROM WAREHOUSE Upon receipt of Material pequisitions (MR) from the warehouse i for salvaged snubber assemblies / parts, the Receiving Inspector shall verify the following: a. The MR identifies the intended use of the material or parts. b. The MR identifies the original mark or support number from which it was salvaged if the part being salvaged is a Code stamped part. c. All material, parts, or assemblies are identified by a unique mark or assembly number traceable to the original support identification for vendor supplied Code stamped parts. d. B&R fabricated snubber assemblies parts or materials and B&R bulk exhibit a heat number which is traceable to an available. material certification.

e. _ All vendor supplied snubber parts, material s, or assemblies are traceable to an available material certification.

Upon completion of the above verification, the Receiving Inspector will sign and date the MR. 4

Upon verification, the QC Inspector shall assure that the above applicable information is recorded on the appropriate form. QC acceptance shall be documented by signature and date in the Comment Section of the QC Checklist for Snubber Installation. 2.5 MATERIAL RE. CLASSIFICATION When a salvaged snubber or part is to be used on a higher Code Class than it was originally supplied for, it shall be evaluated in accordance with Reference 1.E. NOTES: 1) No evaluation i s needed when a salvaged snubber or part is to be used on a lower Code class than it was originally supplied for. -I m A.vm

Prior to commencement of the staking opera tion, cons truction personnel will, notify QC. This notification gives the QC Inspector an opportunity to monitor the s taking operation. Upon completion of the staking operation, the QC Inspector shall inspect the eye rod (or snubber end) to verify the following: a. The eye rod hole is not defonned; b. The bearing race is centered in the eye rod hole and should be staked approximately 1/16" from the edge. However, this dimension is not critical as long as the bearing meets the conditions in C, D and E below. c. The bearing shall be free from rust, dirt and other foreign material; d. The bearing gimbal moves freely in its race. e. The race is secured within the eye rod. 2.2 DOCUMENTATION restaking shall be documented on an Spherical bearing (See Table 1 of this Attachment) and on Inspection Report the MWDC. The support mark number shall be recorded in the " Identification No." block. Completed documentation shall be reviewed and transmitted to Quality Engineering Systems for filing in respective hanger document package. 2.3 NONCONFORMANCES All nonconforming conditions shall be reported in accordance with Reference 1-D. \\ O4D
