-a
- 1. 0 :- PURPOSE, This procedure provides :for she control of Generation Station. Engineer-ing (GSE). calculations by Engineering Services.
2.0 SCOPE
.This procedure applies' to 'all calculations that areLoriginated or revised:'-by GSE. contractors;and vendors. This procedure shall addressi their proper control and . retrieval. ':
~
3.0- DEFINITIONS 3.1 ' Calculation

This includes both the calculation number and the CAR number. The remainder of this procedure will address the indexing forms ~and the assignment-of these identifiers. )
5.1 - Calculation t The as-built calculation is the control document. The original calcu- !
.s, 4 s lation is filed, maintained and revised to represent the.as-built '
condition. !
Pages of the calculation will be consecutively numbered. Each sheet will also show the total number of pages for that calculation. An example appears as Page 1 of 10, Page 2 of 10, etc. .
Multiconnect/ tag calculations are undesirable in as-built form as they i cannot be indexed and filed. Any calculation that collectively ad- !
dresses multiple components may exist only in an active MR or ES file. Once the calculation is as-buf.lt, it must be separated into a t single calculation for each component. If a calculation for the l component already exists then each calculation on file must be revised to show as-built condition.

'l To reduce the volume of superfluous information retrieved by tag k i searches, tags not relating to the information-within are not indexed.
'# Clouded references with 'the -note ". tag (s) not indexed in this calc" ;
indicate this information;is not' recognized.by the CAR system-for this calculation. Not recalling this information simplifies the combining ,
of all relevant information for one component under one calculation 1 number. i New calculations are indexed during t'he design. phase and'are keyworded "Z". They are ' active and are not as-built. They are,not available for reference or revision until as-built by the Design Engineer. t Revisions to existing calculations are.not indexed during the design phase. 1 Calculations that are prepared.to justify a temporary condition will be keyworded " CALC SHORT TERM". If.the temporary conditions become permanent, then the appro.priate calculations will be revised to as-built conditions. Even though conditions are temporary and no perma-nent changes are implemented, the new calculation or revision will be retained. The CAR entry description wil1 be prefaced with " Calc Short Term" then followed by the description. If the package is cancelled
-the calculations are voided.
If short term calculations are revisions of existing as-built calcula- !
tions, they will be considered new.and assigned.new' calculation num- i bers. If short term calculations are revisions of existing short term (7 calculations, the existing calculation is revised and no new calcula-
%; tion is created. ;
5.2 Calculation Index Sheet When revision of an existing calculation is not sufficient, a new calculation is created. Upon preparation, a new calculation will be given a calculation number and logged into the Calculation Index.
Contractor, vendor, or consultant calculations will be indexed upon receipt. The calculation number will be the next sequential number for that station's index. There ~ is a separate index for each station. The station coding and numbering is as follows:
a) Ft . C al houn. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . FC00001, FC00002, e tc .
b) Nebraska City ....... .... .................NC00001, NC00002, etc.
c) Omaha Stations (all other stations)........ 0S00001, 0S00002, etc.

The Cover Sheet. pro-N vides' a', summary forL the attached calculation. .The Cover Sheet is divided into three areas:
a)l CALCULATION' IDENTIFICATION area provides .for the calculation-
$n*$ number, modification / engineering study package, department,'.facili- ,
ty, ' area, system, component tag, calculation title, . safety catego-ry and contractor / vendor ' reference.
b) CALCULATION APPROVAL area provides for revision control and sta-tus. The PREPARER. and CHECKER columns must be signed and. dated along with the INDEPENDENT REVIEWER column when design verifica-tion is required (refer to' B-9 and B-ll). The current. sequential revision number is listed in the REV. NO. column. If this calcula-tion is superseded by or supersedes another calculation the associ-ated calculation numbers are listed in the NEW. CALC. N0. and the SUPERSEDES CALC. NO. columns. The CONFIRMATION REQUIRED columns indicate confirmation status. Signature requirements are indepen-dent 'of confirmation status. See Section 5.7 for guidance on CONFIRMATION REQUIRED.
The job I.D. will be included with signatures for computer calcula-tions.
Calculations received from consultants, contractors, or vendors will have a note placed in the PREPARER / REVIEWER area referencing the attached calculation 'for proper approval signatures and dates.
c)' DISTRIBUTION area provides control of distribution and assures the same distribution when revised.

. g) The remaining fields on the CAR system are non-searchable. These "y;,
't entries are for information only. They will provide the same-information -as they do for drawings with one exception. For.
calculations. the REVISION SHEET NUMBER will indicate the date of the calculation. .The format is year, month, day (yy,mm,dd). The revision date is the latest date that appears with the approval !
signatures for that revision on the Calculation Cover Sheet. !
1 The CAR system is updated by Engineering Services. The Design Engineer is responsible for notifying Engineering Services of tag assignment and keyword choice when the calculation is as-built. .
See Appendix A-11-4 and Section 6.0. Upon notification, Engineer-ing Services will make all entries and revisions to the CAR 1 system.
5.6 Revision Control During the design phase, calculations are developed by creating a new interim calculation or revising an existing calculation. Both will be controlled through the design process. The Design Engineer is 1 responsible for preparing and controlling all revisions.
If an existing calculation is revised, the revisions are made on a copy of the original. An interim revision sheet is attached and all revisions are noted on a copy of the calculation cover sheet below any
,_.. existing revisions that may appear. Interim revisions will start with F~ "
"A" and continue alphabetically. When the modification is updated, the Design Engineer will revise the original calculation. Only the as-built condition will be included. The original cover sheet and revision sheet will be signed and revised to the next revision number.
All interim revisions will remain in the MR file, and the completed !
original will be returned to Engineering Services. !
If a new calculation is required, an interim cover. sheet and revision i sheet will be. prepared. The interim revisions will start with "A" and continue alphabetically. The Design Engineer will complete the index-ing information and obtain a calculation. number when the calculation is initially prepared. Subsequent interim revisions need not be indexed. When the modification is updated the Design Engineer will .i complete a new calculation cover sheet and revision sheet. All !
interim revisions will be deleted and the original calculation will become revision 0. All interim calculations will be left in the MR file and the original will be transmitted to Engineering Services.

5.7 Confirmation 't a) CONFIRMATION REQUIRED-N0 will" be checked when the calculation' inputs / assumptions require no further confirmation, b) CONFIRMATION REQUIRED-YES' shall- be checked when the calculation must be issued to support the design ~ process and contains inputs /
assumptions _which need confirmation. For example, the weight of-a
- 4 valve NE :when ~aisspecificassumed.to valve'behas100been lbs. -selected This assumption will be modifica.-
for this piping confirmed -
. t i o n .' The~ preparer shall clearly identify the inputs / assumptions requiring confirmation within the. calculation body.. .l All calculations .wh'ich require confirmation must' be confirmed. j prior .to as-built status. Removal ~ of the CONFIRMATI0tl REQUIRED-YES status /is accomplished as follows:
- 1) If all inputs / assumptions are confirmed as originally stated, the calculation preparer need only change the Calculation Index and' Cover Sheet CONFIRMATION REQUIRED from "Yes" to "No" and initial and date. 4
- 2) If confirmation ' alters the original inputs / assumptions and impacts the calculation results, the calculation is revised.
The calculation will reflect the new CONFIRMATION REQUIRED ;
status and the new revision. The preparer shall update the ]
Calculation Index and Cover Sheets CONFIRMATION REQUIRED sta- j tus as before. q l
Confirmation must occur prior to the calculation being as-built.

- When a modification is updated the calculations will be listed on the l
l Drawings / Calculations form, Appendix A-11-5, by the Design Engineer. J In addition, the column KEYWORD will be marked CALCULATION or CALC )
SHORT~ TERM 'for the' appropriate indexing of each listing. (See'Sec- l tions 5.1 and 5.5d & f.) The Design Engineer and applicable depart-ment manager will sign the- Drawings / Calculations form and forward it to Engineering Services. q i
If the calculation is a revision, Engineering Services will file the l revised -original received from the Design Engineer. Copies of the interim revisions will be destroyed by the Design Engineer. Calcula- '
tions that are keyworded "Z" remain with the MR or ES file until they are as-built by the Design Engineer or the modification is cancelled or closed. The keyword will be changed, tags added and _the original calculation transferred to the calculation files by Engineering Services at that time.
Calculations that are keyworded " CALCULATION" or " CALC SHORT TERM" are filed together by calculation number. 1 Superseded and voided calculations will be retained in the file sys-tem. The Calculation. Cover Sheet, Index and CAR system are revised to indicate the new condition. The File and Calculation Numbers are unchanged.
Calculations are filed in order by Calculation Number. A folder ex-ists for every calculation number regardless of its status. A folder l will contain a calculation or a notice indicating why not.
The calculation files will consist of two colors of folders: one yellow and one red. The yellow folders indicate calculations complet-ed prior to the fcrmation of GSE in 1975. These calculations may not ;
have been reviewed and approved by GSE. The red folders indicate '
calculations completed after 1975. These calculations have been re-viewed and approved by GSE.
