SUBJECT:
Response to TU Electric Lett er to NRC, Mr . Christopher I Grimes ,
I' Regarding the CASE Documented Request f or Action - Scaling Calculations i r
f REi TU Electric Log #TXX-89850, dated December 21, 1989 {
This memorandum on behalf of the three CASE Monitors as in response to .
the s ubj ec t TU Electric analysis of the CASE Monitors Draft Report i submittal to TU Electric of December 6,1989 regarding the scaling calculation and documentation review concerns originally adsntified to CPSES ,
by Mr . Gary Bodif ord in 1986-1987. Also included are those concerns identified during the monit oring involve ment of TU Electric activities since May 1989 (by CASE and Mr. Bodaf ord), which was an ef f ort designed to resolve hi s c onc er ns . As a point of reference, at should be noted that Mr.
Bodif ord's original aggregat e c onc er ns wer e subs tant a st ed as' cur r ent' existing problems , as evidenced in the results of the TAP audit . ATP 146S, and the results of the CECO /TU Electric technical interf ace meetings (see TU Electric " Action Plan *).
At - t his point in time , at is the position of the CASE Monitors that to respond to each item addressed by TU Electric in Attachment 1 of TXX-89850 would serve no beneficial purpose, since the assues are now before the Nuclear Regulatory Conma s sion (NRC) f or res olution. However , s ome c omment s -
and observations are appropriate and necessary f or clarification.
~

I I )
e l
,a t;' .
In summary, the responses provided under the 'TU Electric Additional I ' Comment s
- c olumn d o not address the f acts. In all cases , an a straightf orward manner , confuse the assues by speaking an generelttaes rather than to the specific concern, and these solutions to *1solated i f
problems" are too narrowly f ocused f or CPSES to properly address the pr ogr ammatic is s ues .
In response to a epecific revision of the initial TU Electric response TXX-89850 to the CASE Draf t Report (contained in TU Electric Letter , Log 87XX-90009, dated Januar y 5,1990, CASE It em 1.10), CASE recognizes s ome ponitive statements (although not without qualifiers) utilized by TU Electric in resolving Mr. Bodif ord's concerns as sociat ed with the NCB1/NCB11 and NCH circuit cards. Had TU Electrac's initial responses to all of Mr .
Bodif ord's concerns utilized a samtlarly positive approach, it would not i
have been necessary to raise these matters to the level of a dispute. The TU Electric revised response stated, in part (pages 5 and 6 of 11):
'TU ELECTRIC WISHES TO EMPHASIZE THAT IT DOES NOT CONTEND THAT ITS ACTIONS ADDRESSING SCALING CALCULATIONS WERE, IN ALL CASES. EFFECTIVE. ENCLOSURE 2. PAGES 3, 4, & 5, INDICATES THAT THERE WERE ACTIONS THAT WERE NOT PROPERLY TRACKED TO I CLOSURE BY SWEC IN RESPONSE TO TU ELECTRIC *S MAY 10, 1988 '
MEMORANDUM DIRECTING ACTIONS ON SCALING CALCULATIONS, fURTHER, HAD MR. BODIFORD NOT RAISED HIS CONCERNS AND TU ELECTRIC INITI ATED THE TAP AUDIT, THE INTERCHANGES OF NCB1 '
AND NCB11 PRINTED CIRCUIT CARDS AND THE USE OF NCH CIRCUIT CARDS MIGHT NOT HAVE BEEN IDENTIFIED FOR CORRECTION. A CAR WAS INITI ATED TOR bOTH INSTANCES. THE CAR INVESTIGATION '
RESULTS ARE NOW AVAILABLE FOR BOTH SUBJECTS, AND IN NEITHER 0F THESE CASES DID THE IDENTIFIED CONDITIONS RFSULT IN A ',
l TAILURE TO PERFORM AN INTENDED SATETY FUNCTION, TAP WILL CONFIRM THAT THE RESPONSE TO THE CAR SATISFACTORILY ADDRESSED BOTH THE SPECIFIC AND PROGRAMMATIC ISSUES IDENTIFIED IN THE CAR.

- WITH RESPECT TO NCH CARDS. CECO ENGINEERING REQUESTED ADDITIONAL SEISMIC ERROR DATA FROM WESTINGHOUSF,. UPON RECEIPT OF THIS DATA. CECO ENGINEERING EVALUATED ITS IMPACT ON THE SETPOINT AND LOOP ACCURACY CALCULATIONS. THIS DATA L WAS INCORPORATED INTO THE CALCULATIONS AND FOUND TO BE WITHIN THE ACCEPTABLE MARGIN ALLOWABLE IN THE CALCULATIONS. FOR MOST CASES. THE RESULTS OF FOUR CALCULATIONS WERE FOUND TO BE OUTSIDE THE ALLOWABLE MARGIN ASSOCIATED WITH THE ORIGINAL CALCULATIONS. THESE CALCULATIONS WERE REVISED TO BE CONSISTENT WITH THE NEW SEISMIC ERROR DATA. AND NEW SETPOINTS WERE ISSUED. EVALUATION OF THESE MINOR ADJUSTMENTS IN SETPOINTS IDENTIFIED NO SAFETY CONCERNS. THE ENVIRONMENTAL QUALIFICATION GROUP WAS PROVIDED THE NEW SEISMIC ERROR DATA FOR INCORPORATION INTO THE APPLICABLE QUALIFICATION REPORTS.
THERE ARE NO REMAINING CPEN ITEMS ASSOCI ATED WITH THIS ISSUE.
WITH RECARD TO THE NCB1/NCB11 CARDS. CECO ENGINEERING REQUESTED OPERATIONS TO IDf;,NTIFY THE CURRENT AS-BUILT LOCATION OF NCB1/NCB11 CARDS. AFTER REVIEWING THIS DATA.
CECO ENGINEERING ISSUED A DCA TO REVISE APPLICABLE DRAWINGS 70 REFLECT THE AS-BUILT CONFIGURATION. TO ADDRESS THE ISSUE OF FUTURE DOCUMENTATION CONTROL FOR THESE CARDS. IT WAS DETERMINED THAT APPLICABLE DESIGN DOCUMENTS AND DRAWIN_GS SHOULD BE REVISED TO ALLON UTILIZATION OF EITHER CARD AND TO IDENTIFY ANY LIMITATION / RESTRICTIONS ON THE USE OF THESE CARDS. . .
(Emphases added.)
While the CASE Monitors agree with the actions taken by 70 Electric to resolve the technical issues associated with the circuit cards and the supporting engineering definition documentation. at as not clear to the CASE Monsters that the QA programmatic breakdown, which allowed those technical concerns to exist since Mr , Bodif ord first identified them in 1986, will receive the same level of eff ort to prevent recur r ence of _ its generic implic ati ons .

The position of the CASE Monitors an the Draf t Report cubnd t t ed December 6,1989 f urther emphasized in the Final Report (1/ (yet to be r eleased) and this memorandum, as that TU Electric was f or a number of years in noncompliance with the requiremente mandated by 10 CTR Part 50 Appendix B, which r esult ed in a deficient , unauditable scaling calculation and documentation review program at CPSES.
TU Electric and its supplier , Stone & Webster Engineering Corporation (SWEC), did not properly and thoroughly investigate and subsequently resolve 1
the concerns adentified by Mr. Bodif ord, who first came to them as a concer ned employee. This inaction allowed those concerns to remain, in excess of two (2) years , even though TU Electric directed SWEC to implement corrective action over a year and a half ago (NE-19097).
With f ew exceptione , the CASE Monit ors
- Draft submittal appears to have been unpersuasive to TU Electric . This becomes visable on page 1 of the ref erenced TU Electric letter which states , in part: I
. . . [T]hus. TU Electrac's ref erences to the overall portions of its previous documents supporting each such paragraph were considered suflacient to document TU Electric's position, which was not chanced by any of CASE's aroument s ." (Emphasis added.)

- 1. TU Electric's Report Heading:
- TU Electric's Action Plan Relatino t o Seals no Calculations is Adecuato.*
CASE Nonit or s ' R e s pons e :
Our evaluation of the *TU Electric Action Plan
- only dealt with .
the specific items included an the TU Electric submittal. The
" dispute" as specifically documented an detail on the 203 pages preceding Att achment 2 of the draf t submittal. The TU Electric' Action Plan is a very f ocused document , dealing only wa th the mechanics of r.
developing scaling calculattons stemming f rom a controlled scaling calculation and documentation review program, and does not deal with 1-the CPSES QA programmatic breakdowns profiled by the CASE Nonators or the deficiencies / observations recorded by the TU Electric TAP auditors in ATP-89-146S.
The 'TU Electric Action Plan
- was initially developed in response I
to a meeting between the CASE Nonitors and TU Electrie/ CECO personnel approximat ely one-third into the conduc t of TAP Audit ATP-89-1463.
Tha s
- Action Plan
- was a ndependent- of t he TAP Audit end did not reflect any preliminary findings. of the TAP Auditors at that point an the ,
4 perf ormance of the TAP audst. As stated above, the TU Electric I
- Action Plan
- resulted f rom technical discussions between TU
. Electric / CECO / CASE personnel dealing with the maj or scaling calculation controlling documents and Westinghouse documentation used as the design i-
.e basis. The TU Electric
- Action Plan
- has developed into a total
- action plan
- encompassing the TAP ATP-89-146S audit results, and a 5

?
plan that CASE has on . numerous occasions recommended and requested that TU Electric control by a f ormal Corrective Action Request (CAR).
Following is f urther explanation of the genesis of the '" Action
' Plan" and the events immediately f ollowing receipt of the plan by CASE. i f=
-1) The original " Action Plan" received by CASE was not dated or +
i E
signed. It was the understanding r,f the CASE Monitors that this plan was a response to the technical meetings held with
.TU Electric management and CECO technical staff personnel, i
This " Action Plan" was not understood by the CASE Monitors to ~ ,
present the TU Electric approach in resolving Mr-. Bodiford*s
< gate concerns, but rather that it was , in f act , follow-
= ution to .the May 10, 1988, memorandum NE-19097 direction s
- .esolve certain of Mr . Bodif ord's concerns , coupled with
-i
-ne results of the technical meetings .
- 2) Af ter the CASE Monitors acknowledged general concurrence with
-i the TU Electric basic '" Action Plan " the CASE Monitors concluded their assessment of the overall lack of the CPSES Proj ect's QA compliance with 10 CTR Part 50. Appendix B, and requested that the TU Electric Director of -Quality
- " - Assurance issue a Stop Work Order (SWO) that would require
"- the issuance of a f ormal Corrective Action Request (CAR) to verifiably track the resolution of the issues to a lasting i'
corrective action.
- 3) The TU Electric Director of Quality Assurance declined to issue a Stop Work Order based on his evaluation of the 6

l f
conditions and r equirements , and t o dat e , t o the bes t knowledge of the CASE Monitors , has not issued a CAR 4ealing
- with the overall . specific and programmatic issues requiring !
correction. The CASE Nonitors have repeatedly stated their i view-that TU Electric, by its lack of action in not issuing _;
a SWO and subsequent CAR, is in noncompliance with essential elements'of its own Quality Assurance program and is consequently in noncompliance with critical f acets of 10 CFR- q Part 50, Appendix B (e.g., Crateria II, XVI), and 10 CFR 50.55(o).
Therefore, it remains the CASE Monitors' position that a Stop Work Order (SWO) and a Corrective Action Request (CAR) were required under the 1
pr ovisions of NEO Procedure 3.25, and are necessary in order to verifiably. [
track and correct the CPSES QA programmatic breakdowns encountered with the scaling calculations and documentation review ef f ort c onc er ns identified by L s
Mr . Bodif ord and CASE, and that potential adverse generic implications, also-identified by the CASE Nonitors in the " Documented Request for Action -
Scaling Calculations ." mus t be evaluated and resolved in a verifiable manner .
- 2. TU' Electric's Report Meadina:
"TU Electric's Safety-Related Calculations are Technically Adequate "
i TU Electric's Statement (in part ):
a) " CASE attempts to avoid this f act by arguing that the real 'end product' is the safety-related calculations, and not the field conditions (see e.g., CASE Report, Page 3 Paragraph 2 page 174).
7 i
w - ,
.q a,
- s.
from this CASE evidently inf ers that the existance of deficiencies an' the documentation underivina the calculations necessarily means that the end product (the calculation) is deficient." (Emphasis
- added.)
CASE Monit ors' Res pons e s a), ' Per the CASE Monitors' compilation of the statistics . TAP Audit ATP-89-146S'alone (not including the technical meeting results) recorded sixty-six (66) deficient ins t anc e s r esulting f rom twenty-one (21) questions investigated pertaining only t o the five -
. (5) safety-related calculations audited, not the underlying documentation /2/.
The CASE Monitors did not need to *inf er ,* as TU Electric has stated, that the calculations were " deficient
- TU Electric itself document ed t hi s f ac t . The CASE Monitors did not take issue with 3 actual " field conditions," either bef ore or subsequent to the TAP audit ATP-89-146S. It is the CASE Monitors' understanding that the combined purpose of the t echnical int erchange meetings and TAP -
L audit reviews was to investigate Mr. Bod 1f ord's and. CASE's safety-related and Balance of Plant (BOP) non-saf ety-r elat ed concerns dealing strictly with the technical concerns and the lack of programmatic controls involving the scaling calculation and documentation r eview ef f ort being conducted by SWEC at the CPSES facility. The TAP audit questions listed below were to assure L2/ See listing which f ollows of the specific TAP audit ATP-89-146S questions asked and subs equent audit deficiencies recorded. It should be noted that if one (1) question reported five (5) examples of ,
deficient conditions, the CASE Monitors counted that as five (5) deficiencies, not one (1) deficiency.

This CPSES Proj ect QA philosophy is, in the assessment of the CASE Moni t or e , a significant indication that TU Electric needs to revisit and re-evaluate the requirements mandated by 10 CFR Part 50.

a) An auditable program did not exist at CPSES supporting the development . . maint enanc e , and control of scaling calculations :
b) Specific technical and programmatic concerns (deficiencies) identified by Mr . Bodif ord over 2-1/2 years ago continued to exist ,
J uncorrected' or unresolved, in the scaling calculation and documentation review ef f ort ,
c ). A deficient Design Basis Doc ument (DBD-EE-032) (now deleted),
existed which was a fundamental engineering deflodtion controlling document for NSSS and' BOP scaling calculations :
d) Westinghouse and CPSES scaling calculation design input ~ and i controlling document s . wor e obs olete ,- uncontrolled, and deficient (e.g., Westinghouse WCAP 9696, 1-SC-8800): and, s

i It is clear to the' CASE Monitors that, with f ew exceptions and f or
- the most part, TU Electric has gone to greet lengths not' to openly admit -I t
that' Mr . Bodif ord had legitimate conc erns . They have attempted to provide rationale and justification f or each CASE Monitor concern, without documenting that the specific and aggregate concerns were' based ,
on f actual existing program def ects and resulted in substantial problems , requiring extensive resources to respond to the concerns. 1 Instead TU Electric stated that resolution of the scaling calculation and documentation review concerns "were timely." However , t his is not supported by the f act that it has taken TU Electric over 2-1/2 years to 23/ " Political," as used in this report, does not refer to partisan politics, but rather to an assessment based on some combination of cost, schedule, regulatory c oncerns , rate issues, public image and appearance, as opposed to strict adherence to t echnical, programmatic, and design criteria required to meet 10 CFR Part 50, Appendix B .

by TU Electric in dealing with the identification and resolution of the scaling calculation and document ation revs ew deficier.cies . Although the l'
December 6.1989, report submitted by the CASE Nonitors was an Draf t b f orm. At was dotatled with sufficient f acts to clearly conclude that TU Electric has yet to perf orm an in-depth probable r oot caus e analysis of
- . the scaling calculation and documentatson review ef f ort , In the view of the CASE Nonitors, there is a need f or TU Electric to develop an approach which considers their plant as a whole, rat her than tr eating i as sues as isolat ed events .
The CASE Nonators were and are extremely concerned about the generic amp 11 cations of a QA programmatic breakdown an the scaling calculation process by TU Electrac's allowsng fundamental QA program violations to exist , especially af ter the history behind the CPSES pr oj ec t , In the view of the CASE Nonitors , the possibility exists that problems an the St ation Service Water System (SSWS) and Auxiliary feedwater System (ATW) could perhaps have been minimized or even avoided altogether had TU Electric responded promptly and ef f ectively when Wr ,
o Budiford first brought the problems with the scalang calculations to TU's attention.
The possibility should now be considered that , had TU Electric put into place an effective root cause analysis pr ogram at _t hat time, and i
had such a program already been in effect and fully cperational at the ;
i time of the SSWS and AFW a ncident s , thos e ancidents night have been averted. The CASE Monitors believe that such a possability should ba included in any f uture in-depth root cause analysis which is perf ormed.

, In conclusion TU Electric's approach to address and resolve the technical and programmatie def acs oncies identaised an the scaling I
calculation and documentation review ef f ort was , in t he assessment of the CASE Monitors , lacking an comprehensive analysis regarding the p potential f or adver s e generic progr ammatic impact , and lacking an i i
U recognition of 10 CTR Part 50 Appendix L, noncompliances . Ther ef or e, t
the CASE Monitors remain concerned about whether ef f ective and adequate total corrective action on these assues can be obtained.
Although the CASE Monitors working on the scalang calculation offert were not involved in t he operating license proceedings . it is !
interesting to note that s ever al points discus s ed an the CASE Monit ors' Draft Report a nd in t hi s response are similar to those discussed in the Atomic Saf ety and Licensing Board's December 28, 1983. Memor andum and i
Order (Quality Assurance f or Design), and February 8.1984, Memorandum and Order (Reconsiderattort Concerning Quality Assurance f or Design).
Although these samalarities might conceivably be viewed as simply a >
dif f er ence of opinion, a nt erpretation, or preference, these samslarities were andependently concluded by individuals not c og na zant of what i
transpired in 1983-1984. Those Licensing Board Orders stated, in part From the Atonde Saf ety and Licensing Board's December 28, 1983, Memorandum and Order (Quality Assurance for Design):

From the Atonde Saf ety and Licensing Board's December 28 1983. Memorandum and Order (Quality Assurance f or Design)
(c ontinued):
- 0ur tour through Appendix B begins with the Introduction, which pr ovides that an applicant must have a quality assurance plan f or deston and construction of sta nuclear pl a nt . We do not consador at f ortuitous that design as listed first. Quality assurance f or design log;cally precedes quality assurance f or construction, w}1ch conf orms construction to design. We f ind t hat this theme recurs throughout Appendix B.
" Paragraph I of Appendix B specifies the estabisshment of
' t he qualit y as sur anc e pr ogr am,' which shall escure that activaties af f ecting the saf ety-related f unctions have been correctly performed.' Nothing an this section is limited to construction activities . It encompasses all activities af f ecting saf ety, including design activities .
- Paragraph II requires that the quality assurance program be established 'at the earliest practicable time' and that. 'The applicant shall recularly review the status and adequacy of the quality assurance program.' (footnote omitted.) Thi s concern about the timeliness of quality assurance is echoed an Paragraph XVI, which requires that " conditions adver se t o quality (bel . . promptly identified and corr ec t ed.
- Paragraph XVI also contemplates the identification and correction of the causes of significant deviations from quality: it r equires the reas onably prompt identification, documentation and correction of deficiencies. {F oot not e omitted.)
"The need f or prompt identification of deficiencies as consistent with 10 CFR 50.55(e)(1), which requires that the holder of a construction permit 'shall notif y the commis sion of each [significant] deficiency f ound in desson and construction, which, were at to have remained uncorrected, could have adversely af f ected the saf ety of operations of the nuclear power plant . . . .' { Foot not e omit t ed . ) It is apparent that f ulfillment of the obligation to report design deficiencies to the Comadssion requires that an applicant have an ongoing quality assurance program f or design and that its program must have the capacity t o spot , track and resolve s ignific ant design deficiencies on an ongoing basis.

- The importance of design control also as recognized in l' Appendix B paragraph III. The first sub-paragraph of t hat paragraph recognizes that design documents have a commanding place in the qualit y contr ol s yst em because t hose documents
