l 1.3 DEFINITIONS 1.3.1 WEB (Walls, Embedments, and Beams)
WEB is a computer program, developed by Westinghouse, used to monitor and qualify embedded plates.
1.3.2 CPSL Drawing Comanche Peak Support Location (CPSL) drawings are computer generated and reflect the WEB database for embedded plate geometry, projected attachment size, and attachment location.
j 1.3.3 Embedded Plate Embedded plates are steel plates flush with the concrete surface and anchored to the concrete with Nelson studs.
The purpose of the plates is to provide a weldable O.
surface for future support attachments.
1.3.4 Footprint Loads (FPL's)
FPL's are attachment loads at the face of an embedded plate expressed in the LOCAL COORDINATE SYSTEM (see ).
FPL's for attachmento cust be calculated for two conditions - Design and Faulted.
These conditions are defined as follcws:

Level A or' Level B whichever is higher FAULTED =
Level C or Level D whichever is higher b.
Non-Seismic Each discipline or discipline designee shall apply a seismic factor to the deadweight load as dictated by their governing procedures.
1.3.5 Attachment
" Attachment" is any permanent steel welded to the face of an embedded plate. Threaded Nelson studs used for one support shall be classified as one attachment if the distance from the centerline of one Nelson stud to the next does not exceed 12" (e.g. Junction boxes, conduit straps, etc.)
1.3.6 Field Engineering
" Field Engineering" is the Brown & Root organization responsible for surveying and for performing field walkdowns.

2.2 Support No. and Support Attachment No.
Enter the support number.
When the support number is not available, a unique number shall be temporarily i
assigned by SEG.
Temporary " support numbers" shall be replaced by the responsible discipline with a unique 4
identification number traceable to the load calculation 1
number.
The support number shall contain no more than s
j seventeen (17) characters (i.e., numbers, letters, j
hyphens and blanks).
If the support number exceeds 17 l
characters, the discipline must abbreviate it.
Each attachment shall be assigned a letter, beginning vith "A".
For example, if a support has five attachments, only three of which attach to embeds, then the first attach =ent to an embed is A of 3, the second B of 3, and the third C of 3.
For this example, 3 FPL 4
forms are required, one for each attachment to an embed..

CPSL sketch.
Room # - Enter the appropriate room number.
Line 2:
Fill in the attachment length and width.
"X" is the dimension of the attachment along the width of the embed; "Z"
is the dimension of the attachment along the lenath of the embed.
