Impell Corp. memo #0210-040-063, dated 6 June 66 D2ar Mr. Warapius In response to your referenced memo, Unit No.1 indeed has cable trays identified as targets.
Cable trays are considered essential targets if they
- contain.. cables required to safely shutdown the plant as a result of the initiating pipe break.
f analysis determines that this interaction is unacceptablejeither he target or source is relocated or a physical nodification (e.g.
et shield) is installed.
All such unacceptable interactions in Unit No.1 have been eliminated by the method indicated above.
Damage Study's original walkdown identified Train C raceways as targets, but these were eliminated from consideration since they are not required for safe shutdown.
If there are any further questions please contact Robert G. Leo at CPSES, extension 8043.

INSTRUCTION FOR CALCULATION PACKAGE PREPARATION 1.0 GENERAL a
l The preparation and documentation by Civil SAC New York of calculations for cable tray hangers (CTH) shall conform to Company Procedure E-30 and these j
Instructions.
l The Instructions are needed to achieve with a simple, and well documented approach, good traceability while accounting for the specific conditions required for the design verification of the CTH for CPSES Units 1 &
2.
1
. of these instructions are guidelines to be used in the Unit No. 2 j
Calculation Backfit Program. The portion of this program related to calculation j
package format describes formatting to be used for Unit No.1 as well as 1
Unit No. 2.
All documenta which are utilized as ~a source of input or as a reference, and i'
all calculations produced in the cable tray hanger design verification program shall be bound in books at s central location for easy retrieval-and usage.
j()
Two separate volumes consisting of a series of books, one set assigned to Volume I and the other set assigned to' Volume II, shall be established.
2.0 ORGANIZATION OF CALCULATIONS IN BOOKd 2.1 volume I In general, the books included in Volume I shall contain documen'ts consisting of the project design criteria, general instructions, design aids, i
studies, computer data and usage information, computer program verification j
reports, and cable triy hanger group design classification procedure and l
data. Each book inclu,ded in Volume I shall have a general Taole of Contents listing all documents contained in Volume I.
2.2 Volume II l
All calculation books containing cable tray hanger (CTE) design verification calculations and associated computer analysis output runs shall be incorporated into Volume 11. All final and superseded cable tray hanger calculations shall be filed together. Likewise all final and superseded computer analysis output runs shall be filed together.
3.0 FORMAT OF CALCULATIONS FOR GROUPING OF HANGERS ThedesignverifYeationrequiresthateachCTHhasacalculation pa ckage. However, due to many similarities between hangers with the same l
geometry (same spatial configuration) some hangers are grouped so that the design verification of only one " representative envelope" (RE) of the group serves as either the co:plete or partial basis for the qualification of the 11491 1

whole group. When used as a partial basis, the forces and/or stresses from the analysis of the RE are used for design verification of specific features (welds, anchorages) of each hanger in the group.
Grouping is the process whereby, per grouping procedure in Volume 1, cognizant engineers compare all known elements influencing hanger structural response and select the " representative envelope" hanger which, once design verified, documents the rest of the group. If nona of the actual group hangers are judged to be a representative one then the one closest to the representative envelope may be enhanced with attributes (loads, spans, etc.) from the other hangers to create an " idealized" representative envelope. In all calculations 1
and documentation, the " representative envelope" hanger is called representative, for simplicity oaly.
4.0 CABLE T*AY HANGER CALCULATION TRACEABILITY Each hanger which does not have an individual calculation and refers instead to a calculation made for the group representative, shall be documented by a calculation package consisting of a cover sheet, table of contents, reference sheet (Exhibit 1) referencing the group representative, and l
Attachments E, F, H, I, J and K as described in Section 5.0 below as applicable.
As the calculations are completed, a computerized cross-reference list is kept available for ready retrieval of any calculation.
i The revision of a calculation may be required by the revision of the hanger as-built data, revision of design criteria, design guidelines or both.
Wherever a revision of the calculation is made without requiring changes to the hanger drawing, a note on the cover sheet shall so indicate.
5.0 SPECIFICS OF CALCULATIONS l
Each hanger calculation shall be prepared as per Ebasco Company Procedure E-30 and these instructions. The cover sheet of the calculation shall be as shown in Exhibit 2.
The signature in ink of the preparer, checker and reviewer on the cover sheet is limited to a confirmation that the Calculation Package has been properly prepared in accordance with the Project Procedures and this guideline. Compliance with technical and design criteria requirements vill continue to be the responsibility of the preparer and the checker of the individual calculation pages.
For Calculation Packages issued prior to the publication of these guidelines, I
the> current revision of the Calculation Packages will be documented as outlined above. Previous calculation revisions will not be backfitted on the i

Introduction l
To ensure that all final Comanche Peak SES Unit No. 2 eable tray hanger
)
design verification calculations conform to the latest Ebasco Design Criteria and Instructions (References 1 and 2) and Ebasco Engineering Procedures (References 3 and 4), a Calculation Backfit Program has been instituted. The portion of this program related to calculation package format describes formatting to be used on Unit No.1 as well as Unit No.
2.
O This program consists of a systematic review of the technical and format aspects of each cable tray hanger design verification calculation packsge and, if required, preparation of revisions to these calculations j
and/or associated drawings. The review of each package shall be accomplished by using the Calculation Format and Technical Backfit j
Worksheets (Appendix K Exhibits 7 and 8). The guidelines in this I
attachment describe the use of these worksheets.
III. General Guidelines l
1.
Prior to initiating a backfit, the backfit originator must confirm, 1
through the Supervising Design Ihgineer, that the calculation i
package and drawing in hand are the most recent revisions. If revisions subsequent to those in hand have been made by the site, the latest revisions must be obtained through the Supervising Design Engineer prior to backfit initiation. Any site' calculations shall be merged with NY calculations as part of the backfit effort. In addition, the backfit originator must establish through the Supervising Design Engineer the current construction status of any j
modifications indicated on the most recent revision.
2.
At the top of each worksheet, the calculation number and revision number identifying the calculation package under review shall be entered. Next, the support for which this calculation applies shall i
be identified by support drawing number and revision number. Also, all other supports for which this calculation applies as a result of grouping shall be similarly listed in the space provided.

d 1299R
nev 4 1/24/86 f;
APPENDIX K Rev 3 12/20/85 Page 15 of 26 In ge eral, any support requiring nember nodification should not be part of a group unless all hangers in the group have very similar modifications.
If, as a result of the backfit, regrouping is required, then regrouping should be performed and the Grouping Imad j
Engineer should be notified immediately in writing.
i 3.
The symbol legend shown on each worksheet defines the symbols to be used in fining out the rarksheets. All spaces must be fined in.
The backfit originator (person performing review and backfit if required) shan use his experience and judgement to ascertain whether each ites listed has been correctly, conservatively or incorrectly considered, or omitted, in the calculations in l
l accordance with References 1 to 4 and sound engineering practice, and then enter the appropriate symbol after each iten. iihere j
specific values are requested (eg. stress interaction give i
critical value), the originator shan enter the =nh= valuas shown in the calculation.
+
In determining whether a particular ites which has been conservatively considered should be marked with a (/) or (z), the reviewer must determine whether or not the conservatism has significantly affected the need for and extent of a hanger audification. If an as-built hanger passes with a conservative value, then this is acceptable.
If, however, the use of a conservative value resulted in a hanger modification, then this itea must be considered incorrect and the conservatism must be reduced to j
minimize the required modification, unless, of course, the modification has already been constructed at the site, in which case the modified support must be backfit. If, as a result of the backfit, a modification is required for a previously passed as-built hanger, notify the Supervising Engineer immediately in writing. He win review the results and at his discretion initiate response i
spectrum dynamic analysis, and if necessary, time history dynamic analysis, to attempt to demonstrate hanger adequacy.
i i
Any incorrectly considered or omitted items must be corrected by the i
backfit originator as a calculation revision, and drawing revision j
if required. If a drawing revision is required, it shall be i
accomplished in accordance with Ref 5.
If the backfit originator determines that an omitted ites has no significance on calculation results, he should modify the calculation by simply adding a statement explaining why the omission is of no concern. Likewise if a conservative approach has been used, a statement to this effect should be made in the calculation (ie. if OBE allowables were j
i compared with SSE loads because this is conservative and does not result in a support modification, a statement to this effect should il be included in the calculation). Statements such as "by inspection" or "by engineering judgement" should not be used. Instead, the l
basis of the judgement should be written down in the calculation.
If site calculations contain such a statement, the backfit i
originator should determine if the statement is correct and, if so, leave it as it is.
Ultimately, af ter the backfit is completed, all items on the worksheet must be marked with either a (/) or (N/A).

V 4.
The backfit originator shall sign and date the bottom of each worksheet. The backfit checker shall, after checking any calculation made by the originator and resolving any differences he may have with the originator, complete, sign and date the Design Verification Checklist Forn 599 and then sign and date the backfit work sheets. The backfit worksheets and Form 599 shall be filed as calculation package attachments, and copies distributed as noted at the bottom of the worksheets.
The general guidelines above apply to both worksheets. Detailed guidelines for each ites of the Technical Backfit worksheet and for selected items of the Format Backfit worksheet follow below. Guidelines stated in III.3 above regarding conservative values sust be strictly adhered to.
IV.
Detailed Guidelines - Technical Backfit Worksheet For each ites on the Technical Backfit Worksheet, a short description highlighting what should be checked is presented below. These descriptions are not meant to completely describe every aspect of each item, but only the aspects which are acet suspect. The backfit originator must review each item for conformance to References 1 to 4 and sound engineering practice.
1.
Computer Program: STRUDL version 0385 or 0985 -
Only computer runs made using acceptable S versions (0385, 0985 or subsequent acceptable versions) of STRUDL can be included in calculation packages. STRUDL versions other than 0385 or 0985 any have been used very early in the job, and for such cases the analysis must be rerun. For baseplate analysis only, STRUDL version 0185 is also acceptable.
2.
Geometry: Boundary Conditions - Eccentricities -
Boundary conditions used in either computer or hand analysis must accurately r~eflect actual anchorage configurations as specified in Section III of Ref. 2.
l Eccentricities used in computer or hand analysis must be considered per Section IV of Raf. 2 to realistically account for the application of loads and interconnections between structural members. Some of the attachments referenced in Section IV of Ref. 2 (RO) have been revised and incorporated into subsequent revisions.
Tray loads should be applied to the support members at two points.
3.
Ioads:
a.
Thermolag -
For each tray run and its associated hangers, it must be determined if thermolag is applied. In doing so, Act. D of Raf. 2 and the supplementary Auxiliary Building Added Scope Thermolag list provided R
