1.0 GENERAL 1.1 PURPOSE i 1.1.1 This procedure establishes location and spacing criteria for I all attachments on embedded plates in the walls, beams and ceilings of plant buildings to assure conformance with re-quirements of Specification 2323-SS-30. It also provides a means for the responsible craf ts to inform engineering of all (BOP and Non-BOP) attachments to strip plates and large plates {a\\ in the Units I and II. [5P!88&?!?8886 PDR

PROCEDURE EFFECTIVE CPSES NUMBER REVISION DATE PAGE-(s/ } JOB 351195 CCP-45 4 9/30/86 2 of 7 1.2 SCOPE 1 1.2.1 This document establishes location and spacing criteria for j all permanent (BOP and Non-BOP) and temporary attachments on embedded plates. In addition, this procedure controls the transmittal of infor-mation pertaining to BOP attachments on embedded plates and cites the reference documents which establish these criteria. The requirements of this procedure shall be followed except when specifically detailed otherwise on the originating en-gineering organization's drawing or upon issue of a pertinent design change. 1.3 GENERAL DISCUSSION 1.3.1 This document addresses the 3/4" thick plates anchored to the building walls, beams, and ceilings by Nelson Studs, attach-ments to these plates, and the location of these attachments on the plates. These plates provide structurally competent surfaces to which attachments such as pipe supports, cable tray supports, 3 -s HVAC supports, etc., can be permanently attached by welding. The j need for proper location of the supports on the plates is to avoid placing loads in areas of insufficient strength due to Nelson Stud location or proximity to the edge of plate. This procedure does not ' apply to embedded plates which are intended for permanent attachment of specific structures (e.g. platforms, stairways, equipment, e tc.). 1.4 RES PONSIBILITY 1.4.1 The proper location, minimum spacing requirements of attach-ments, and the compliance with this procedure shall be the responsibility of the superintendent of the craf t engaged in the installation of the attachments, i l 1.5 DEFINITIONS 1 1.5.1 " Strip Plates" are steel plates 3/4" thick, either 8" or 10" wide and of various lengths which are anchored to concrete surfaces by embedded Nelson Studs. 1.5.2 "Large Pates" are steel plates 3/4" X 4'-0" X 8'-0" or 3/4 X 9'-0" X12'-0" which are anchored to concrete surfaces by em-bedded Nelson Studs. This includes plates of either of these nominal sizes which were modified to include cut-outs or ir-regular shapes to conform to building configurations. 1 '~ .-------.-r m,- -g, m- ,-- - - - w ..y- ---+-e n. -r-

See. 1.5.4 " LOADED NELSON STUDS" are those studs located within 12" along the length of a strip plate or within 12" along the length or width of a large plate, measured from the face of an attach-ment. See Attachments 8 and 9. 1.5.5 " STRUCTURAL DiBEDMENT GROUP" (SEG) previously known as WEB is the engineering organization responsible for evaluating and qualifying embedded plates. l 2.0 PERMANENT ATTACHMENTS i l 2.1 LOC ATION 2.1.1 New or rework attachments to embedded plates in Unit I require Civil /SEC approval (indicated by the engineer's signature on an FPL, see Attachment 3) prior to installation. In Unit II, ,s ( ) only those installations that do not adhere to the design document N' / or this procedure require prior approval. 2.1.2 Atachments to large and strip embedded plates shall be separated a minimum of 12" from the face of an adjacent attachment (s) (See, Figure 2), unless specifically shown on the design document. The 12" minimum shall be maintained even if the adja-cent supports are located on different plates. (See Attachment 10). When the 12" separation cannot be maintained due to field conditions, the responsible engineer shall be notified prior to in s talla tion. An evaluation of this condition shall be performed and if found acceptable, this condition shall be shown on a design doc ument. Separation criteria do not apply to 1/4" diameter Nelson studs welded to the embedded plate for the purpose of supporting con-duit identfication tags. Unless specifically approved otherwise, welding shall be done using a maximum interpass temperature of 350* F on 3/4" embedded plates. ] 2.1.3 Loaded studs due to attachments te embedded plates shall provide the required clearance indicated in Attachments 5, 8, and 9, unless otherwise shown on a design document. If the stud location is not known, the minimum separation to an opening or loaded Hilti bolt / I Richmond insert shall be measured as described in Attachment 8 of this procedure. 2.1.4 Embedded plates which have separation violations with concrete 7s ( expansion anchors or Richmond inserts may be rendered unusable N/ by the Civil /SEC Group af ter an engineering evaluation has been made.

For attachments in Unit I and common, an approved FPL must be attached to the traveler before support installation. If an approved FPL is not attached to the traveler, the responsible engineer shall be notified and an FPL originated. Attachments to Unit II may be installed without an approved FPL provided the support can be located according to design documents or the criteria established in this procedure.

SUBJECT:

CCP-45 Revision 4 "CCP-45, Revision 4 was issued 9/30/86 as a major rewrite with signi-ficant changes in the documentation requirements for attachments to em-bedded weld plates. This revision was distributed based on the presup-position that logic would dictate when and how the documentation transi-tion would occur based on this and other related procedures. However, it has been brought to my attention a certain amount of confusion may exist with regards to proper documentation proceedings. The following elucidation should be distributed to all control copy holders of CCP-45, Revision 4. It must be rationalized that fabrication and documentation for attachments to embedded plates may have been at any of the belov stages when CCP-45, Revision 4 was issued and should be treated accordingly: 1. Attachments not installed - installation and documentation in accordance with CCP-45, Revision 4. O-l 2. Attachment installation completed - installation and docu-mentation in accordance with CCP-45, Revision 3 is accept-able. 3. Attachment installation and/or removal inprocess - a com-bination of documentation in accordance with CCP-45, Revi-sion 3 and Revision 4, as applicable, commensurate with the stage of activity for a given attachment. For these amal-gama ted packages, it will require that operations previously accomplished per CCP-45, Rev. 3 be marked "NA" on the super-ceding document issued per CCP-45, Rev. 4. "NA" of steps will be performed in accordance with CP-CPM 6.3, section 3.2. Should additional clarification be desired, I may be reached on .l extension 8366.

SUMMARY

To ensure the structural integrity of all loaded embedded plates in Unit I, a complete backfit inspection of the embedded plates will be performed. Field Engineering will generate as-built sketches. Civil /SEG Engineering will review the as-built sketches and Q.C. will field verify the information.' Conditions outside of Quality Control procedure QI-QP-11.14'-13 will be documented via NCR. Civil'/SEG will disposition the NCR's. PURPOSE These instructions contain the criteria.to be used by Field Engineering to generate embedded plate as-built sketches and tolerances for Q.C. verification. l-SCOPE 4 l As-built sketches depicting attachment locations and spacing dimensions shall be generated for every " Loaded Embedded Plate" in Unit I only. All " Loaded Embedded Plates" shall be accounted for on a defined boundary basis. ' DEFINITIONS 1 F.E. Sketch - Field Engineering sketches are field generated sketches that depict the location of embedded plates and information regarding attachment locations and spacing dimensions affecting embedded plate attachment analysis. l Inspection Package - Inspection packages define accountability traveler and all individual travelers within a room / area. Loaded Embedded Plate - Loaded embeds are steel plates flush with the concrete surface and anchored to the concrete with Nelson studs which through existing welded attachments transfer loads to the concrete structure. e j i .,.s. - - i u..- - --.+.'

r . 3 Page 2 of 6 Loaded Nelson Stud - Those. studs located within 12", along the 4 longitudinal axis, fron the' edge of an embed attachment. "Ex" - is the attachment location eccentricity from the embedded plate center line. s "F" - is the distance from the edge of an embedded plate to the edge of a penetration or edge'of concrete. "D" - is the distance from a Richmond insert to a loaded Nelson stud (centerline to centerline). "Z"- .is the distance fro's a Hilti bolt to a loaded Nelson stud (centerline to contariin'e). "R" - is'the radius (minim:tm required distance) from loaded Nelson stud to Hilti' bolt, Richmond insert, or free edge of concrete. (Ref. Attachment 7, 8, and 9). I "S" - is the distance from the face of a welded attachment to the 1 face of an adjacent welded attachment. 1 "O" - is the distance form the face of a welded attachment to the edge of a hole on the plate. For illustration purposes see attachment 1. 1 CONSTRUCTION TRAVELER CONTROL The Paper Flow Group will issue construction travelers as requested by Field Engineering. Field Engineering will attach an as-built sketch to . every embedded plate traveler and send the travelers to the Structural Embedment Group for review and approval of as-built sketch. SEG will then release inspection packagee to Quality Control for backfit inspection. Upon completion of the inspection, QO will forward the 1 inspection package to PFG for retention. Copies of all travelers will then be sent to SEG for evaluation. ~. .01 ,~ .----u-- ,t .w +,
