! RBF1-97-0034 l Page 2 of 3 for adhering to our operating license. Additionally, Entergy believes that an effective licensee assessment and corrective action program is essential for identifying and correcting conditions that may exist at a facility.
Prompted by the renewed focus on the design and licensing bases, FSAR assessments were conducted at each Entergy facility last summer. Entergy shared the results of these assessments with you in meetings at NRR (November 14,1996) and Region IV (December 17,1996).
Similarly, upon receipt of the 10CFR50.54(f) letter, RBS and the other Entergy plants jointly developed and implemented an assessment of design basis and configuration management processes. This assessment reviewed the completeness and effectiveness of controls necessary to translate the design basis into current plant configuration and operating procedures. The assessment and its results are described in the enclosed response.
Our reviews determined that no significant design basis concerns exist at RBS.
However, two process discrepancies were identified. These are discussed in          ;
Section X of the enclosed response. Also, various process and control improvements were identified during the development of this response. These         I improvements will be evaluated to determine appropriate actions to be taken.        :
Based on the assessments and reviews conducted, we believe that reasonable assurance exists to conclude that the RBS design basis of systems, structures and components are adequately maintained in the plant.
The on-going program discussions provided in this letter are considered by RBS      l to be enhancements and are not provided as commitments necessary to ensure design basis adequacy.
I The enclosed report covers a great deal of information in summary fashion. We encourage your questions and comment. Please feel free to contact Rick King or Guy Davant of my staff for clarifying information or additional detail. Pursuant i to the requirements of 10CFR50.54(f), RBS is providing the enclosed response to the NRC's request under affirmation.

RESPONSE TO REQUEST FOR INFORMATION                                i REGARDING ADEQUACY AND AVAILABILITY OF DESIGN BASIS INFORMATION l

: 1. INTRODUCTION The purpose of this letter is to provide added assurance that Entergy Operations, Incorporated (EOI) facilities are operated and maintained within their design bases with deviations reconciled in a timely manner as requested pursuant to 10CFR50.54(f) by NRC's Executive Director for Operations on October 9,1996.
This response covers River Bend Station (RBS).
l Although NRC's request focused on specific questions with respect to plant         I design control and configuration management, the request was made against a         '
larger background of concern over licensees' ability to understand, maintain and operate their plants in accordance with a plant's licensing basis. Mindful of this  I broader perspective, EOl has taken steps not only to respond to the specific       I questions but to understand and address the wider messages:                        l
    . NRC's confidence in licensee control of their licensing and design bases has been shaken by events of the last year and a half,
    . Public and Congressional confidence in the nuclear regulatory process has eroded as these events received publicity and scrutiny, and              l
    . Compliance with licensing and design bases is not optional. Compliance is an expected and necessary element of an effective regulatory framework.
Consequently, we believe that the individual and collective responses to the 50.54(f) letters are an essential first step in restoring public and regulatory confidence in nuclear licensees.
Prior to issuance of the 50.54(f) letter, EOl developed and implemented licensing basis assessments at each of our facilities, and developed a design basis evaluation that is presently ongoing. Upon receiving the 50.54(f) letter, we extended these concepts and built upon their insights to implement the critical review needed to respond in a pro-active manner to this letter.
Overali we have found these exercises valuable. In particular, we have identified a number of subtle means to change the configuration of a facility that may

4 ll. BACKGROUND Nuclear plants, processes, regulations and regulators change and evolve over time. EOl's first plant (ANO Unit 1) was licensed in 1974 and its bst facility (Waterford 3) received its full power license in 1985. Over that Sme, the industry and the regulators experienced significant change ranging frcm the TMI accident to 10CFR50.71(e) requirements to update the FSAR. Sirne our facilities were licensed at differing times and subject to differing regulati)ns (e.g., both ANO              l i
units operated for a number of years before 10CFR50.71ie) was enacted), it is not surprising that their internal process development differed.
i         Similarly, the industry and the regulators have undergone significant change                  !
since the lass EOl facility was licensed. The period from 1985 to the present is probably bei characterized as one of increased understanding of the factors important to nuclear safety. Enhanced understanding of, comfort with and use of               l probabilistic safety assessment techniques led to an increased capability to                  !
focus on safety significant elements of plant design regardless of their safety-              !
related or non-safety-related designation. Performance-based approaches to                    l plant operation and regulation started to be applied because they focused on safety results rather than prescriptive details of how a function was accomplished.                                                                                 !
Evolving regulation and evolving understanding of elements important to safety, coupled with varying times of plant design, construction and licensing led to                 )
strikingly different historical development for EOl facilities. This is apparent in           '
how each facility's control and conception of licensing and design basis management evolved.                                                                           i 1
For example, ANO Unit 1 (licensed in 1974) uses an FSAR format based on a predecessor to Regulatory Guide 1.70 and has custom technical specifications different from the standard format. The design bases requirements under 10CFR50.2 for ANO may be viewed as more limited than a plant licensed in the mid 1980s. Consequently, the design documentation expectations under 10CFR50, Appendix B at that time were less demanding and design docunientation was in many cases not readily accessible.
In contrast, Grand Gulf was licensed in 1982, but went through an extended low power testing period due to discrepancies between the as-built plant and the technical specifications. The large technical specification re-validation effort at that time, combined with its later plant vintage, better turn-over from the architect-engineer, and better document maintenance, led to much reduced design basis documentation efforts for Grand Gulf in comparison with ANO.

111. REGULATORY BASES                                                     '
The difference between the design and licensing bases can be confusing and is often not clearly documented. While the distinction may be unimportant in many controlling processes, it is relevant to our response to the 50.54(f) letter and to l   the various assessments EOl has conducted either in response to the letter or as 1
a result of the broader issues which led to the letter.
4 in the 50.54(f) letter, the NRC has clearly couched their request in terms of the 10CFR50.2 definition of design bases. As such, the design basis is a subset of the licensing basis. And, although the licensing basis itself is undefined in
;    10CFR50, in general, EOl facilities view the licensing basis to be similar to the j    10CFR54.3 definition of current licensing basis.
in practical terms (although not strictly correct), the industry tends to think of the i
licensing basis as primarily consisting of the FSAR and the 10CFR50.2 design basis as that portion of the FSAR that addresses safety functional characteristics a    as defined in 10CFR50.2. Consequently, much of the introductory discussion of the 50.54(f) letter which addresses various concerns with FSAR fidelity is
:    concentrating on the licensing basis, while the information request itself
[ Questions (a)-(e)) is limited to that portion of the FSAR that constitutes the design basis.
!    Regardless of the distinctions, as discussed below, EOl has taken steps to address issues associated with both design and licensing basis fidelity.
Design Basis l    The term " design basis" as defined in 10CFR50.2 differs from how we use that term in day-to-day activities. The " regulatory design basis" of 10CFR50.2
:    represents only the tip of the design basis iceberg. Underlying the regulatory
;    design basis is a large amount of design basis information contained in documents such as design documents, calculations, analyses, drawings, tables, databases and the like, which is not part of the regulatory design basis.
Notwithstanding its status outside of the regulatory design basis, management
;    and control of this larger body of information is necessary to ensure that the regulatory design basis of 10CFR50.2 is accurate, and to maintain compliance with 10CFR50, Appendix B.
In responding to the 50.54(f) letter, EOl has chosen to expand our review beyond the narrow confines of the regulatory design basis to identify and
 . examine processes which could affect the broader design basis and plant i

configuration. Although those processes [which are identified and reviewed in Section VI, Response to Question (a)) are extensive, we found our review valuable in identifying and refining controls on plant configuration.'                                     l Licensing Basis L 1st June, recognizing the importance of the licensing basis issues associated
': ath recent industry events, EOl management directed that licensing basis assessments be developed and conducted for EOl facilities to determine if                                  l additional action was needed to maintain and control our plants' licensing basis.                          1 These assessments, which were conducted in July and August,1996 at each EOl plant, were successful in identifying a number of subtle ways in which the plant's operating basis could be changed while bypassing the traditional licensing basis change mechanisms.
While the FSAR assessments and their results are beyond the scope of the 2
50.54(f) request , their insights were utilized in developing the review approach to respond to the 50.54(f) letter. EOl has also shared our FSAR assessment approach and findings with the industry and the NRC. In particular, we met with NRR (November 14,1996) and Region IV (December 17,1996) to provide a detailed presentation on the FSAR assessment results from each facility.
Overall, the FSAR assessments found that traditional licensing basis controls such as the 10CFR50.59 and 50.71(e) processes are effective in maintaining and updating the licensing basis. Process enhancements were identified in some cases to address non-traditional operating basis. At two of our facilities (ANO and River Bend) there were sufficient discrepancies in the original FSAR text to merit an FSAR upgrade effort. That effort, which was briefly described during the NRC presentations, is beginning at the two plants and is expected to be completed in approximately two years.
 ' In addition to the review conducted to respond to the 50.54(f) request, EOl is conducting design basis team evaluations at each of our facilities. Similar to the FSAR assessments described below, the design basis evaluations are expected to yield further insight into useful areas to enhance the design basis documentation and control. These evaluations are scheduled to be complete in 1997.
2 As noted in footnote 8 to the 50.54(f) letter, the Commission has adopted enforcement policy changes to encourage licensees to voluntarily undertake initiatives to identify and correct FSAR noncompliances. We believe the FSAR assessments and other initiatives qualify for such enforcement discretion. EOl will docket this position separately from this response.

IV. RESPONSE DEVELOPMENT AND OVERSIGHT                                          !
Planning for and preparation of the 50.54(f) response was coordinated by an EOl l 4  team of knowledgeable representatives from each facility and the corporate      l
,  office. As directed by management, the team developed a response approach i  (described in Section V, below) involving a critical review of site process     l completeness and effectiveness. The intent was to go beyond process description and develop an approach capable of identifying new insight into the adequacy of design basis and configuration management processes.
Each site assembled a separate team to implement the resulting assessment.
The site team was responsible for investigating site processes, evaluating the resultant information and identifyin0 and documenting any deficiencies or process enhancements. The site team also compiled sufficient records of their review to substantiate the accuracy of the findings.
4 l  One advantage of a system-wide team approach is that throughout the response development period, site-specific findings and insights were shared amongst the EOl team. Common problems were addressed, and, where appropriate, consistency in evaluation and approach was facilitated.
Draft information was shared with nuclear facilities outside of EOl in order to benefit from external insights. Knowledgeable external and legal personnel also
: provided valuable feedback.
The RBS response was reviewed by a broad range of site personnelincluding engineering, licensing, and management personnel. In addition, the on-site safety review committee (Facility Review Committee) performed site-specific reviews.

;    V. APPROACH TO ADDRESSING QUESTIONS (a)-(d)
Before providing the detailed response to Questions (a)-(d), it is worthwhile to discuss how these questions interrelate and our understanding of NRC's intent in 4
posing the questions.
Questions (a) and (d) request descriptive information concerning the design / configuration control processes and the corrective action processes.
Questions (b) and (c) request our reasons for concluding that these processes are implemented such that actual plant configuration and activities accurately
. reflect the design basis. In constructing our review to be responsive to the spirit j    of these requests, EOl focused on addressing two key issues:
     . Completeness [ Questions (a) and (d))
0 Have we identified the ways (processes) by which plant configuration can be changed?
0 Does the corrective action program contain the appropriate elements?
O Do the identified processes contain the elements necessary for effective control?
Effectiveness (Questions (b) and (c))
1 l        0 Do we have previous assessments (e.g., audits, vertical slice inspections, etc.) that provide reasonable assurance of process effectiveness (i.e., that        4 the design basis is reflected in plant configuration and procedure)?
O Have we undertaken major process or other upgrade efforts (e.g., design basis reconstitution, improved technical specification implementation, etc.)        ;
that provide reasonable assurance of process effectiveness?
The concepts of completeness and effectiveness deserve further discussion in i
order to fully understand our response.
Completeness in reality, engineering design, configuration control and corrective action processes are a complex set of intertwining proceduralized processes spanning multiple departments. For example, just in the area of design control there are many processes (and even more procedures) that address different control

RBG-43668 Enclosura Page 10 of 44 mechanisms such as design specifications, drawing updates, internal standards, vendor manual changes, software control, database control (e.g., cable, EQ, seismic, setpoints, etc.), and many other control activities.
The question of completeness becomes more complex when we move beyond the traditional design change and configuration management processes to evaluate other potential ways that plant configuration can be changed. As we found through the FSAR assessments mentioned above, there are a number of ways in which plant configuration can be changed that may bypass traditional configuration control processes.                                                    i There are numerous processes / procedures that can affect, in one way or            i another, plant configuration. Similarly, there are multiple processes that can      l affect corrective action. These processes are listed and discussed in the response to Questions (a) and (d), and in Appendix A.
In addition to identifying the processes by which plant configuration or corrective action can be affected, it is important to identify the elements which should be present in those processes in order for them to be effective. For configuration management, process effectiveness elements control a change from conception to implementation and closure of documentation including update of design files.    ;
For example, initial process effectiveness elements are a design review for         !
compliance with appropriate codes and standards, and a 10CFR50.59 review for        j licensing basis impact. Post-implementation elements include testing to confirm     i function and, if the change is temporary, a provision to revisit the basis for the change or restore its initial condition. For corrective action, process effectiveness elements are also defined. Like the processes themselves, the process effectiveness elements are listed and discussed in the response to Questions (a) and (d), and in Appendix A (for configuration management elements) and Appendix B (for corrective action elements).
Based upon identification of processes and identification of process effectiveness elements we can draw conclusions (with reasonable assurance) about the completeness of our programmatic controls for configuration management and corrective action. This is the focus of our response to Question (a), and the detailed evaluations in Appendix A.
Effectiveness The effectiveness of a process is a measure of how wellit performs its intended function. For example, prior to a change being implemented into plant procedures or design, does the 10CFR50.59 process consistently ensure that

RBG-43668                                                                                             1 Enclosura                                                                                             l Page 11 of 44                                                                                         ;
the change has been appropriately evaluated for its effects on safety and the                         l licensing basis? If so, the 10CFR50.59 process is considered effective.                               l Determining process effectiveness is largely a matter of inference based on a sampling of individual process products. For instance, an audit of the                                i 10CFR50.59 process may sample 20 plant procedure and design changes and                               l find that in each case, the change (prior to implementation) was evaluated in                         i accordance with 10CFR50.59 and that the quality of the evaluation was high.                           !
Although all plant procedure and design changes were not reviewed, the                                l consistent nature of the sampling findings leads to the inference that the 10CFR50.59 process is effective, in responding to the 50.54(f) request, EOl chose to identify and review the results of past assessment activities that in some way either reached conclusions about process effectiveness or developed information from which such conclusions could be inferred. There is a wide array of useful process effectiveness assessments. In the regulatory arena these include inspections by                       )
NRC personnel, SALP reports and safety evaluations. Under EOl's purview, we                            I conducted quality assurance audits, self-assessments, vertical slice system inspections, and upgrades of particular process areas such as design basis documentation upgrades.
The combination of process effectiveness assessment results, over a period of                         ;
time, provides a reasonable basis upon which to draw overall conclusions about                        !
process effectiveness. This is the focus of our response to Questions (b) and (c) in Section Vll.
Finally, this assessment approach is necessarily qualitative rather than an exhaustive revalidation of the design basis. We have made judgments based on our assessments and a standard of" reasonable assurance." By this we mean that we have drawn inferences from our assessments that we feel would be drawn by other objective and knowledgeable people, based on the same information.3
* lt is important to note that this response is not based on a detailed, line-by-line review of a facility's design and licensing basis (which is not possible in the time allowed for this response).
Our response should not be interpreted as a guarantee that discrepancies are not present somewhere in a design or license basis document or that there are no equipment discrepancies.
Rather, it should be interpt eted as a good faith effort to respond to global questions on a limited schedule.

Question (a) requests the following information:
Description of engineering design and configuration control processes,                 l including those that implement 10CFR50.59,10CFR50.71(e), and Appendix B to 10CFR Part 50; As previously discussed, there are two key aspects to addressing this question -
identification of the processes which could affect plant configuration, and identification of the elements necessary for process effectiveness.
Processes which could affect plant configuration are numerous and go well                         l beyond those thought to traditionally constitute configuration management.
Those we considered in responding to the 50.54(f) request are listed below in Table 1.
These processes range from a narrow focus with a single controlling procedure (e.g., maintaining the setpoint list) to broad processes that span several procedures and departments (e.g., the design change process). However,                           !
regardless of scope, they share a common characteristic in their capacity to                     I change some aspect of plant configuration. Collectively, they also represent our judgment of a reasonably complete set of ways to affect plant configuration.
Each of these processes is described broadly for all EOl sites in Appendix A.
In order to effectively control plant configuration, there are a limited set of d
process elements which are expected to be in place . The process elements were derived by the EOl team based on general consideratiorn of configuration 5
management including 10CFR50 Appendix B and the primery licensing / design basis control requirements such as 10CFR50.59 and 10CFR50.71(e). These process effectiveness elements are listed in Table 2.
By their nature, the process effectiveness elements may have somewhat different meanings depending on the process to which they are applied. For
  ' It is important to note that the critical process elements were selected with respect to their importance for design and configuration control as requested in Question (a). An individual process such as maintenance work orders may have a large number of other elements important for the successful implementation of that unique process. However, for the sole purpose of maintaining configuration control while implementing maintenance work orders (or any other process) the applicable elements listed in Table 2 should be present.
5 For instance, see applicable elements of ANSI N45.2.11.

instance, interface controls (#5) fc a design change may be different than                      ,
interface controls for an off-normai piacedure change. In addition, many processes will not be sufficiently broad to encompass all process effectiveness                 '
elements. As examples, changing an internal civil engineering standard for non-                 l category I structures will likely not have any provision for restoration controls l

,         The process effectiveness elements are described in mere detail in Appendix A.                    ;
i By assessing the processes which may affect configuration control (Table 1) against the critical elements necessary to control configuration (Table 2), we can               ,
:         make a judgment as to the completeness of our configuration control processes.8                 l The detailed results of our site-specific reviews for completeness are included in               i j         Appendix A.                                                                                      l Summary of Response to Question (a)
In large measure, EOl facilities determined that those processes (Table 1) and process effectiveness elements (Table 2) necessary for effective configuration management and design control are present and implemented. In particular,
:         RBS determined the following (the details of which can be found in Appendix A).                   i We reviewed each process listed in Table 1 as they are applied at RBS against the key elements listed in Table 2. Of these processes, two are not applicable to                 l RBS: 1) Technical Specification Interpretations; and 2) Steam Generator / Eddy Current Testing Program.
Based on this process review, we have ide,ntified three (3) deficiencies pertaining to the key elements which could lead to inaccuracies in the design basis and licensing basis. These deficiencies are identified and discussed in the Conclusions section of Appendix A.
Over the past four years, RBS has been conducting performance improvement plans. [The Near-Term Performance improvement Plan and the Long-Term Performance improvement Plan are discussed in Section IV, Response to Questions (b) and (c)] These activities have focused on improving performance in three key areas:

procedures, as well as plant configuration and performance, accurately reflect      I the design basis. And, we provide our judgment as to the effectiveness of those activities and processes.
RATIONALE 

==SUMMARY==

Entergy has reasonable assurance that the RBS design basis requirements are properly translated into operating, maintenance, and testing procedures and that the system, structure, and component (SSC) configuration and performance are consistent with these requirements.
The plant design bases were documented at the time the site was granted an operating license. Based on assessment activities performed over the past several years, Entergy has reasonable assurance that RBS had maintained its

RBG-43668 Enclosura Page 18 of 44 programs and processes with potential to impact design bases in accordance with the applicable criteria of 10CFR50, Appendix B. These activities, while supporting this conclusion, have resulted in enhancements that are expected to provide additional support and assurance of the control and maintenance of the design bases.
a This assurance is substantiated by the following key points:
: 1. RBS is a relatively new plant, receiving its operating license in November, 4       1985.
: 2. Although weaknesses were identified in various processes used to maintain the design basis information, broad-based assessments performed by EOl as part of the merger with Gulf States Utilities (GSU) provided reasonable assurance that the RBS design basis was known and available.
: 3. Verification and formal determinations have been performed that provide reasonable assurance of the effectiveness of the established processes for operating, maintaining, and testing the facility in accordance with its design basis.                                                                         .
: 4. Necessary configuration management and design basis-related                               I improvements have been implemented to protect design basis information.                 !
The processes which control plant configuration and design basis were                    l identified, reviewed, and found to contain the elements necessary for                    l effective control.                                                                       !
1 BASELINE RBS received its operating license in November,1985. RBS was acquired by EOl as part of a merger with GSU. Broad-based assessments conducted at RBS around the time of the merger provide reasonable assurance RBS had control of its design basis. These assessments provided evaluations of the condition of RBS relative to design and license bases and identified shortcomings in various aspects of plant performance. Consequently, the merger period serves as an appropriate baseline to begin response to Questions (b) and (c).
As a result of these evaluations which occurred during the merger period, RBS                !
management initiated improvement programs to address declining performance i

RBG-43668 Enclosurs Page 19 of 44 trends. These programs were the Near-Term Performance Improvement Plan (NTPIP)7 and the Long-Term Performance improvement Plan (LTPIP)8 The NTPIP was implemented in December,1993 to address underlying causes of significant performance issues and put into place immediate actions to achieve performance improvements. These activities were intended to be implemented over the first half of 1994 while the LTPIP was being developed.
The NTPIP identified broad performance areas which included configuration management concerns. Those items not complete at the conclusion of the NTPIP were incorporated into the LTPIP.
RBS management provided progress updates to the NRC in periodic meetings both at the site and at Region IV headquarters throughout the six-month life of the NTPIP.
Specific configuration management areas addressed by the NTPIP included:
. Drawing Upgrade Project: incorporated near-term, high priority drawing changes
. Vendor technical manuals: incorporated near-term, high priority changes into vendor manuals
. Design document usability and accuracy: improve design documentation
. Resolve NSSS drawing problems
. Evaluate configuration management issues against drawings critical to Operations to ensure design drawings accurately reflect the updated physical plant The LTPIP has been a 3-year effort developed to continue the improvement processes estabiisiied and Nrther identified under the NTPIP and to broaden the scope of assessments. It inc?udes 21 wide-range improvement initiatives for RBS programs and processer. including those involving configuration control.
RBS management has met wi'.h the NRC periodically providing status updates.

* Submitted to the NRC via letter RBG-40428, dated 3/28/94. The LTPIP was also presented and discussed in the 1/5/94 public meeting referenced in footnote 7.

RBG-43668 Enclo:ura Page 20 of 44 The LTPIP contains several sections which address configuration control and maintenance of design basis information. These are:
* Sections 11, " Materials Management"
* Section 12, " Modifications"
* Section 14," Engineering Support"
. Section 22, " Preventive and Predictive Maintenance" Further discussion of the LTPIP is contained under the POST-MERGER ACTIVITIES section below.
Recognizing the importance of configuration management, RBS management also commissioned a Configuration Management Assessment (CMA) of RBS configuration management practices and processes. The CMA was performed by the Configuration Management Assessment Team composed of technical experts inside the company as well as outside consultants. The CMA resulted in a comprehensive plan addressing configuration management and design basis maintenance. The results of the assessment are documented in " Configuration Management Assessment Team Report," dated November 7,1994.
The following excerpt from the executive summary of the report identifies its scope and clearly demonstrates correlation to the actions required under the NRC 50.54(f) letter, as clarified in a letter from NRC Chairperson Shirley A.
Jackson to Mr. J. F. Colvin, President and CEO of the Nuclear Energy Institute, dated August 14,1996.
    "The assessment performed by the CMA Team included:
e   comparisons of plant as-built configuration vs. documentation, e   evaluation of design-bases documentation (calculations, System Design Requirements Documents (SDRDs), System Descriptions (SDs), etc.),
e   evaluation of plant documentation routinely used by operations, maintenance, engineering, training, and procurement (drawings, procedures, databases, etc.),

A variety of configuration management-related issues were identified by the CMA Team. Each was evaluated for significance and generic implications. None of the issues (individually or collectively) constituted a significant safety concern or warranted plant shutdown.
Corrective actions recommended in the CMA Report were addressed in Condition Report (CR) 95-0102, " Configuration Management issues, Root Cause          j Analysis Report," dated May 26,1995. CR 95-0102 evaluated the root causes for the identified conditions and established appropriate actions to correct the conditions and to prevent recurrence.

The LTPIP included numerous assessments and improvement initiatives as discussed under the BASELINE section above. In August,1996, the LTPIP was evaluated to determine its effectiveness and subsequent impact on RBS                           3 performance. This evaluation concluded the LTPIP has been effective in                          j improving overall RBS performance, with certain areas still requiring elevated                  {

RBS management presented the results of the LTPIP effectiveness review to the NRC in a meeting on September 18,19968.
Surveillance Test Procedure Review On July 10,1996, we discovered a Technical Specification (TS) surveillance test had not been performed within its required frequency. Subsequently, the plant was taken to Mode 4 to perform the surveillance test."
In response to this incident, RBS management assembled a team composed of senior engineering staff and management personnel of varying backgrounds and experiences to review surveillance test results. The scope of the review included cold shutdown surveillances with 18 months or greater frequency.
Approximately 370 Surveillance Test Procedures (STPs) were reviewed by the                      l team. The team identified numerous concerns regarding STP performance. The                      !

Also, a follow-up evaluation was conducted to ensure identified problems were properly dispositioned.
This TS surveillance review provided RBS management with reasonable assurance of operability.
1 Internal Assessments Entergy believes a strong self-assessment program is essential for safe, reliable plant performance. Assessments are performance-based evaluations of site functional areas, using industry standards of excellence as measures of             i evaluation. Corporate assessments are used to address large functional areas,       I such as vertical slices of Operations, Maintenance, etc., or horizonts' slices such as Safety Culture and Human Performance. These are staffed by subject matter experts, both from inside Entergy and frora outside organizations. Site-based assessments are more narrow in scope, for example, focusing upon a system, or a specific program.
Since 1993, RBS has undergone several self-critical program assessments which evaluated processes involved with control of the design basis and in translating design bases into drawings, specifications, and procedures. These include:
. Motor Operated Valve Program Assessment 1
. In-Service Testing Program Assessment
. 10CFR50.59 Program Assessment
. Emergency Diessi Generator Program Assessment in addition to program assessments, the RBS Quality Assurance department has conducted various program assessments in accordance with 10CFR50 Appendix B. These have included:
. Safety System Functional Assessments (SSFAs) and Safety System Functional Inspections (SSFis)
. Audits of the RBS design control program and design modifications to existing plant configuration.

. Emergency Diesel Generator Program Assessment in July,1996, a self assessment of the RBS Standby Diesel Generators (DG) was performed at the request of the RBS DG System Engineers. This self assessment was a milestone of a site initiated DG Improvement Plan. The self assessment team was comprised of six team members and included personnel from the Southern Nuclear Company, Waterford 3, Grand Gulf Nuclear Station, the EOl corporate office, and RBS Quality Assurance. Team members were selected to assure a high level of DG expertise.
The self assessment purpose was to review and evaluate the adequacy of RBS DG program. The assessment identified four strengths and three areas needing improvement. Specific recommendations and comments were compiled and entered into a tracking database to assure the full benefit of assessment recommendations. Recommendations included Technical Specification enhancements, operating procedure changes, and improvements in maintenance and trending.
. Safety System Functional Inspections (SSFls) and Safety System Functional Assessments (SSFAs)
The methodology used in conducting SSFis and SSFAs includes vertical-slice techniques and criteria. SSFis and SSFAs consist of a team of highly qualified and experienced evaluators focused on a specific system or systems to examine the design, operation, testing and maintenance of the system. One SSFI has been conducted since the merger. It is discussed below.

in accordance with the NRC's Final Rule on Technical Specification                        ,
j         Improvement, this effort included modifying the TS to clearly reflect the                 !
design basis of the plant with a focus on reviewing the TS requirements                    t j        against the design basis presented in the USAR.
As part of the development effort, the TS Bases were expanded to help insure that the design and licensing basis are understood as they relate to the TS. The expanded Bases also provides plant personnel with easier
!         access to design basis information. This greatly aids personnel when performing various evaluations (e.g., operability evaluations, engineering
:         evaluations, safety evaluations per 10CFR50.59).
As part of the project to prepare for implementation, approximately 340                    1 procedures were reviewed and revised as needed to ensure proper                            l implementation of the TS requirements. This review included a review of the
~
method of performing logic system functional tests (LSFTs) by comparing the procedures to the system logic drawing (s) and ensuring that the logic
:         required to be tested was tested. Changes were made where appropriate.
      . Procedure Upgrade Project Beginning in 1995, RBS embarked on a project to upgrade approximately
,         2200 technical procedures. The upgrade process elements applied during l         the upgrade process re-validated design and licensing basis criteria in the upgraded procedures. Plant walkdowns were used extensively throughout
.         this validation effort. The types of procedures which were included in the i        upgrade were:                                                                              j

These discrepancies were corrected as they were identified.
I There are procedures which were not included in the Procedure Upgrade                         I Project. However, the change requirements specified in RBNP-001, " Control                    ;

In addition to the Procedure Upgrade Project, a project was completed in 1993 which developed a matrix of STPs involving TS-required logic system functional tests (LSFTs)12. As part of this project, procedures were compared to the TS, USAR, and plant drawings to ensure that the TS requirements for                    ;
each LSFT were met. During the development of the matrix, discrepancies between procedures and design basis documents were iceqtified and                             i corrected.                                                                                    '

            . Simulator Configuration Management RBS has established a simulator configuration management system to maintain the simulator for effective training support per ANS/ ANSI 3.5-1985.
Configuration management requires controlling the simulator design and design data. This control ensures that, as reasonably achievable, the simulator reflects the plant in performance and appearance. This program implements simulator configuration management by defining the process required to maintain and update the simulator, associated equipment and documentation.                                                                  ,
1 The simulator configuration management system, among other things, verifies the current simulator configuration complies with the functional and physical fidelity specifications described in the simulator design data.
Approved design changes are reviewed for simulator impact and incorporated into the simulator following field installation and simulator testing.
Other Supporting Information RBS conducted reviews of Licensee Event Reports (LERs), NRC inspection reports, Condition Reports, and Employee Concerns issues submitted / identified since the merger for configuration control-related items. These reviews are discussed below.

issues. For each violation, actions were identified and entered into corrective action processes to address these issues and prevent recurrence.
Weaknesses were identified involving valve and handswitch mispositioning, and failure to properly translate design basis information into procedures.
RBS has received several violations in these areas and initiated actions to prevent recurrence.
* Condition Reports                                                                  l l
RBS management encourages plant personnel to use the Corrective Action Process, of which CRs are an integral part, to identify issues of even minor significance. This low threshold of condition reporting allows early identification of trends, thereby reducing the number of significant conditions identified. Numerous minor deficiencies have been identified since January 1994, some of which were escalated in significance when taken collectively.
These resulted in formal root cause analysis.
. Employee Concerns                                                                 '
The Employee Concerns Coordinator reviewed concerns from the merger to identify any items pertaining to configuration control. He found none pedaining to this subject area.
Several of the LERs and violations involving configuration control involved human' error. RBS management is presently undertaking actions to address the overall human performance issue at the plant.

Vill. RESPONSE TO QUESTION (dl l              Question (d) requests the following information:
Processes for identification of problems and implementation of corrective
;                                  actions, including actions to determine the extent of problems, action to j                                  prevent recurrence, and reporting to NRC; As in the response to Question (a), there are two key aspects to addressing this question - identification of the processes which could affect corrective action, and identification of the elements necessary for process effectiveness.
Unlike the processes examined in response to Question (a), there is only one                             I
.!             corrective action program. Most criticalis the link between the corrective action
,              process and those processes which could affect configuration management. We
;              confirm that link exists by explicitly including " deficiency identification and .
!              resolution" (i.e., corrective action) as one of the essential elements (Table 2) for j              configuration management.

~
We cannot overstate the importance of the corrective action process for effectively managing plant configuration (or any other process important to nuclear safety).' It is the self-correcting mechanism that leads to the continuing health of whatever process to which it is applied.
It is essential, therefore, that the process effectiveness elements for corrective action be well-defined and understood. At EOl facilities, those elements                                 j (contained in Table 3) are largely common.
l Each element is described in more detail in. Appendix B.
The corrective action process at each EOl facility is regularly reviewed through vehicles such as quality assurance audits and self-assessments. While process deficiencies have been identified over the years, they have invariably resulted in programmatic enhancements.
Much of the evolution of corrective action processes at EOl facilities is due to the recognition of the unique importance of this process to plant safety and future                          :
performance. Each site has gone through one or several conscious efforts to                              !
lower the threshold on problem identification and increase the quality of various elements of the corrective action process, particularly root cause evaluation.

The Corrective Action process was identified by Entergy Operations executive staff as one of the company's key processes. Tha Corrective Action Key Process Team was chartered in Mart '',1993 to analyze the existing processes at each Entergy Operations facility and make recommendations for process improvements.
The team's short-term goal was to identify and address any current program weaknesses and share process strengths. The short term enhancements included various process adjustments, but more importantly, the changes included the development of common terminology, threshold criteria and measurement plans to enhance the capability to measure, trend and compare performance at each facility.
The team's long term goal was to converge the variNs processes towards a "best" process including the development and implementation of the following process improvement examples:
    . An integrated database for documenting adverse conditions
    . Significant condition sharing between facilities
    . A common approach to root cause analysis at each facility
    . Common threshold criteria at each facility for identification, significance classifications, and required root cause analysis
    . Common performance measures and goals for each facility
    . Identification and elimination of excessive processes and process steps These ongoing initiatives have improved the corrective action process and are expected to lead to further process enhancements in the future.
The primary objective of the RBS Corrective Action Program is to assure that conditions adverse to quality, such as failures, malfunctions, deficiencies, deviations, defective material and equipment, and nonconformances are promptly identified and corrected as required by 10CFR50 Appendix "B". A secondary objective endorsed by management, is to identify and correct problems at the lowest level possible. It is management's belief that significant problems can be minimized if the minor nonconsequential problems (precursors to more significant events) are identified, documented, corrected, trended and analyzed.

RBG-43668 Enclosuro Page 39 of 44 i
The CR is the primary Corrective Action process at RBS supplemented by the Security incident Report (SIR) and the Stop Work Directive (SW). Beneath these processes are a group of lower tier " feeder" problem reporting processes which are intended to accomplish the secondary objective (e.g., Maintenance Action items, drawing change notices). The supplemental Corrective Action Program processes and the " feeder" processes have the potential to cross a threshold where a CR must be generated. Procedure RBNP-030," Initiation and Processing of Condition Reports," describes the threshold, as does each sub-tier system implementing procedure. Users of each process must write a CR when that threshold is crossed.
EOl management endorses and believes that the backbone of the station is a strong Corrective Action / Problem Reporting Program. Management supports and encourages identifying problems. Identifying the minor nonconsequential problems allows the assignment of a standardized code to problem reports so
;  that they may be trended and analyzed to predict and subsequently preclude the significant problems, as well as allowing for efficient traceable correction action.
The databases for appropriate problem reporting systems resides on a common database management system. Trend and problem codes are assigned and i
then periodically assessed. The results are provided to management at appropriate intervals. Problem codes are assigned by the department owning each feeder system.
in 1993, the RBS Corrective Action Program was revised to incorporate CR review by a Cond!Uon Report Group (CRG), a group comprised of RBS directors and managers (or their designees). The CRG reviews CRs for significance level.
4 A CR may be deemed significant requiring a formal root cause analysis presentation to a management approval committee, the Corrective Action Review Board (CARB). The CARB discusses the root causes and corresponding corrective actions.
I Recently, the Corrective Action Program was revised to provide more consistent classification and trending. New CRs are screened by the in-House Evaluation and Assessment (IHEA) group, with input from the trending group, for significance and recurrence and assigned a significance level. The CRs are then presented to the CRG for review and approval of the significance level assigned by IHEA.
As with other processes at RBS, the Corrective Action Program is assessed to determine its effectiveness and identify areas of improvement. Assessment 1

1 activities include QA audits and surveillances, and self-assessments. Recent activities are discussed below.
e      June,1996 Corrective Action Audit In June,1996 a six month Corrective Action Audit was conducted. .The purpose of this audit was to evaluate the effectiveness of corrective action taken to correct deficiencies affecting nuclear safety that have occurred since December 1995. Condition reports were issued as a result of this audit. The CRs were not considered significant and did not affect plant safety or                  j reliability. The Corrective Action Program was found to be reasonably                   ;
effective in providing assurance that conditions adverse to quality are                 l
                        . promptly identified. It was determined that, based on the number of                     I deficiencies, additional management attention was needed.
                   .      Corrective Action Program Self-Assessment During the fourth quarter,1996 RBS conducted a self-assessment of the                ,
Corrective Action Program. The objective of the assessment was to evaluate the program as follows:
0 Evaluate the administration of the condition reporting process (tracking, trending, reporting, etc.)
0 Evaluate the adequacy and completeness of corrective actions                          l
                                                                                                                '1 0 Evaluate the adequacy and completeness of root cause analyses 0 Determine willingness of employees to identify and document problems Areas for improvement were noted and are being addressed.
The assessment concluded the Corrective Action Program is effective. The                !
assessment team made several recommendations which would further                        l strengthen the program and improve efficiency.
Based on this self-assessment, the specific process review conducted for this letter (see Appendix B), and other assessment activities, we have reasonable                   ,
assurance that the Corrective Action Process at RBS is effectively implemented.

The overall effectiveness of your current processes and programs in concluding that the configuration of your piant(s) is consistent with the i
design basis.
4 in Section V, we discussed the strategy taken for responding to Questions (a) -
(d) by focusing on two key issues: 1) completeness, and 2) effectiveness.          !
In responding to Questions (a) and (d) (see Sections VI and Vill, respectively),
we addressed completeness by identifying the configuration control and corrective action processes which should be present and the key elements these processes should contain. Our process review results indicate the following:
e   RBS is employing the identified processes
      . The processes, except where noted, contain the key elements necessary to be effective.
We have evaluated the identified deficiencies and have determined they are j   non-significant and have not led to a significant degradation of design basis information.
In responding to Questions (b) and (c) (see Section Vil), we identified and discussed the activities which evaluated and assessed RBS configuration control
:     processes. We also discussed several improvement initiatives which utilized design basis information and supporting information gathered from reviewing LERs, NRC inspections, CRs, and Employee Concerns.
Based on information gained from these activities, we have reasonable assurance that the configuration of the plant is consistent with the design basis.

==SUMMARY==
OF FUTURE INITIATIVES                                                      l The 50.54(f) letter has provided the opportunity to view as a whole our design        ,
basis implementation and initiatives. In the course of conducting an assessment to respond to the letter, we identified certain areas of improvement as well as       ;
compiled the ongoing initiatives related to design basis and configuration management.
Tiie following initiatives are a mix of pre-existing activities that were ongoing or planned at the time of the 50.54(f) letter, and new initiatives based upon additional insight gained during our 50.54(f) assessment. We believe the combination will be effective 'in advancing the RBS design basis beyond the level discussed in response to Question (e), above.
: 1. River Bend has begun the System Design Criteria (SDC) Project. The SDC Project is currently in progress. The project is discussed in more detail in Attachment 1.
: 2. Entergy is conducting design basis team evaluations at each facility. The purpose of these evaluations is to determine what additional actions may be       l needed to improve the linkage and integration of the design basis into plant programs and procedures, and the SAR. The design basis evaluations are expected to yield further insight into useful areas to enhance the design basis. The RBS design basis evaluation has begun and is expected to be completed in February,1997.
: 3. As a result of the EOl FSAR Assessment activities, RBS is planning to conduct a USAR Review Program. The objectives of this project are to review the USAR to ensure it:
    . Contains the information required by NRC Regulatory Guide 1.70 e   Accurately reflects design and operating procedures The project is a 2-year effort currently scheduled to begin during first quarter, 1997.
In addition to the above activities, RBS is taking actions to address process deficiencies identified in the configuration control process reviews. These deficiencies are discussed in Appendix A.

As discussed in Section VI [ Response to Question (a)), in order to make a                    i judgment about the completeness of the processes that could affect plant configuration, it is necessary to identify such processes and determine the configuration management elements that are necessary for effective                            l configuration control. This Appendix provides the results of our completeness                 :

elements necessary for effective configuration management processes. Each                      ;
element in the table is also described below. As discussed in Section VI, every process element may not be applicable to each configuration control process.
Those elements which are applicable to a process are part of the process description (although, for brevity, they are not repeated for each process).                    I in this Appendix, we combine the configuration control processes (Table 1) with their essential elements (Table 2). Below, we first summarize our findings and conclusions regarding the completeness of site processes necessary to change and maintain plant configuration control. We then review each process, note the procedure (s) that implement that process in whole or in part, and determine if applicable process elements are present in the procedures (should a process element be missing, we also note the plans to repair that omission).
It is important to recognize that processes and procedures have developed separately and under different conditions at each of the EOl sites and, therefore, the mechanism for implementing each of the processes is typically going to be different; in some cases, implementation of a process element may be found in a secondary procedure and therefore, would not be contained in the specific procedure cited. In other cases, a single procedure may be adequate to                          ,
completely control a process at one site where at another site, it may involve                 i multiple procedures.

Based on this process review, we have identified two (2) deficiencies pertaining to the key elements which may lead to inaccuracies in the                            !
design basis and licensing basis. These deficiencies and actions to correct them are listed below.

: 2. A discrepancy was identified in the FSAR Update process in that there is no mechanism in place to ensure design basis documents are reviewed and updated, if impacted, for USAR changes initiated outside the design change process.
]     These deficiencies have been entered into the Corrective Action Program for                                  i further evaluation and action.
Description of Design and Configuration Control Process Effectiveness Elements (Table 2)
 . Following are the descriptions of the process effectiveness elements listed in Table 2 for design and configuration control processes. These elements are considered integral parts of the process descriptions discussed in the following section, but, for brevity, are not repeated in the process descriptions.
Element #1 - Design Basis Review l
This element sets the expectation that the proposed change will be reviewed to determine if there is an impact on the design basis (both the 10CFR50.2 design j     basis and the underlying design documents) and, if so, a judgment made as to the acceptability of the change with respect to the design basis. Inherent in this i     element is a review to determine that the change is compliant with required / committed design codes and standards (which are a subset of the design basis).
      ' This Appendix contains summary information. The detailed individual site review results and descriptions of site-specific processes are contained in the documentation files located at the RBS site.

This element, which begins with a 50.59 review, applies to any process which                   !
could change the facility or procedures as described in the SAR, and results in                ;

1 The 50.59 programs for the four Entergy Operations sites have undergone significant improvement in the last six years and continue to incorporate new and j                                improved means to understand, identify and document 50.59 reviews. The l
50.59 programs at each of the Entergy Operations facilities are very similar, and              !
i                                primarily only differ in the documentation process. Each of the site 50.59                     l programs contain the following elements                                                        >

!                                            is performed on facility changes, temporary changes, procedure changes,            l j                                           tests and experiments and SAR discrepancies against designated                      I j  :                                        licensing basis documents including NRC SERs. These screenings i
include a review of SAR text, figures and tables that is documented on i
established 50.59 forms and retained in permanent records for retrievability. In general, documentation consists of identifying what a                                           documents were searched, the means of how the search was conducted,
;                                           the computerized search criteria and a summary of findings (although j                                           there are some site-specific differences).
l
                        *
* Electronic Search Capability: The licensing basis documents are primarily l                                           searched using a comprehensive full text searchable computerized
,                                           database. This database uses an indexing system that allows complete                l l
searching of the documents for potential impact by use of individual, i
multiple word strings or Boolean searches. Searches can be performed
;                                           typically in a matter of seconds. This SAR search system provides a
!                                           highly reliable tool in finding potential text areas where the SAR can be i                                           impacted.
i e     Application of USCf criteria: With only a few exceptions, the criteria for
;                                           determining an unreviewed safety question (USQ) are identical at each
!                                           EOl site. In most cases, the guidance is similar to, or based on, that              !
j                                           provided by NSAC-125. The evaluations for determining a USQ are j                                           documented and receive on-site safety committee review.

* Periodic Review: The 50.59 process is periodically reviewed to determine j                                      process effectiveness and compliance to regulatory requirements. This          i

n EOl facilities also use the 50.59 review as a convenient way to trigger other         l licensing / design basis control processes. The initial 50.59 review (termed a        l l                              50.59 " screening" at EOl facilities) determines if the following additional process l                              sub-elements (all of which are considered a part of Element #2) should be             l l'                             invoked:
s j                                  e   10CFR50.90 - A license amendment request for prior NRC approval of a
;                                     change will be generated if a Technical Specification change is necessary or should the proposed change constitute an unreviewed safety question l
;
* 10CFR50.54 - Acceptability of a proposed change to the QA Program, the l                                     Emergency Plan, the Security Plan or certain aspects of the Training l                                     Program will be evaluated under the appropriate requirements of i '
10CFR50.54 and may result in a request for NRC approval prior to implementation
!                                  . 10CFR50.71(e) - Potential changes to the SAR due to the proposed change are identified in the course of determining if 10CFR50.59 applies       ,
to the change (i.e., does the proposed activity change the facility or         l procedures as described in the SAR?). If there is an impact on the SAR,        i the SAR change process is invoked, resulting in an update to the SAR following implementation of the change (and on a schedule consistent with the requirements of 10CFR50.71(e)).
Element #3 - Review and Approval Process                                              l This element provides review of a process product by person (s) other than the         !
executors of the process to identify any deficiencies, inconsistencies, inaccuracies or other problems before the product is approved and issued. It          !
applies to any process that could change the plant configuration. It offers additional assurance that no mistakes have been made during the execution of the process that could compromise the effectiveness of the product and also that the process has not adversely affected the design basis of the plant. This may i

RBG-43668 Appendix A Page 5 of 38 include independent verification required for design control and peer, supervisor, management, plant safety committee review, etc. for process control changes.
Element #4 - Document Update Controls This element requires that, when changes in the plant are made, whether physical or operational, the design basis is updated to reflect the changes in a timely manner. Applicable processes contain appropriate feedback mechanisms to ensure that the design authority is notified of changes to the design basis that have been implemented (i.e., installed in the plant, implemented in plant operational procedures, etc.). Applicable processes also contain controls to maintain the pedigree of design basis information affected by a change (i.e.,
identification, distribution, document update and record storage).
Element #5 - Interface Controls This element ensures that the process contains instructions to notify or interface with all appropriate organizations / functions when the plant configuration is being changed. This may be either a specific reference for interface to a function / organization or a general consideration of the organization / function that could be impacted, and may include either distribution of information or direct contact. This element is essential to ensure that applicable organizations revise appropriate documentation in a timely and consistent manner to operate and maintain the plant and train personnel in accordance with the as-built configuration.
Element #6 - Restoration Controls Applicable processes contain appropriate steps to verify that the product of the process meets the design basis expectations, and that controls exist, as needed, to ensure that plant changes undergo a confirmation test. This may include post-modification, post-maintenance or performance testing of plant systems,
- structures and components to verify that they will perform as expected, or other confirmation activities such as validating computer software (i.e. is there a means to ensure that the change meets the expectations for which it was designed?) Failure of the plant to function per the design could invalidate the design basis.
Element #7 - Deficiency Controls As discussed in 10CFR50, Appendix B, Criterion XVI, deficiency controls are needed to ensure that conditions adverse to quality (e.g., failures, malfunctions,

f            RBG-43668 Appendix A j            Page 6 of 38
)-           deficiencies, deviations, defective material anc equipment, and nonconformances) are promptly identified and (orrected. Each EOI facility has implemented a corrective action program to satinfy this criterion. The corrective action program itself consists of key elements which are described in detail i            following Table 3.
4
;            As required by each facility's policy, the provisions of the corrective action
;            program are applicable to any site activity potentially affecting nuclear safety.    )
i            This element ensures that a process contains provisions for documenting, correcting and reporting products that do not conform to the acceptance criteria for the process. If the process does not require a condition report, is there a      ;
specific mechanism to address and correct the condition (i.e. drawing revisions,
;            SAR errors, inaccuracies in design documents, procedure improvements, etc.)?
j            inherent in this element is the expectation that the process must have
!            acceptance standards by which the product can be evaluated. It may also include acceptance standards that must be met during the process in order for l            the process to continue.
Element #8 - Revisiting Temporary Changes i            By their nature, temporary changes (such as temporary alterations) typically l
receive a safety review (e.g., Element #1, Element #2) applicable only for a limited period of time, in order to ensure that the design and licensing basis       j review assumptions are maintained for temporary changes, as well as to confirm the continuing safety of the change, it is necessary to revisit such changes prior j
to expiration of the time period for which the review is applicable. This element is relevant only to those prccesses which can generate or control temporary changes.
Process Completeness Review l
Each process identified in Table 1 is described, and examined against the applicable criteria of Table 2 to determine if the process is present and if the applicable process effectiveness elements are implemented. Where omissions are identified, they are so noted along with a brief description of plans to correct !
the deficiency. Procedures which implement the process are also noted.               l The matrices below cordain one of three potential values:
                  .   "Y"- the configuration management process element should be, and is,        !
contained in relevant site procedures

CONTROL OF CONFIGURATION DOCUMENTS:
Design configuration documents are of various types and classes that define the                                     ,
design bases and criteria; translate those bases and criteria into the final design;                               l and depict the final design that is installed, operated and maintained. A design configuration document may be used as input to any process or activity affecting plant configuration. Most design configuration documents are considered to be "living" documents in that they are maintained current with the physical plant.
Design ' documents fall into 3 broad categories2; e    Design input - which document design criteria, parameters, bases, and other requirements upon which the detailed final design is based,
                . Design Process - which document the design practices and activities that substantiate the final design, and
                . Design Output - which depict final design, and define technical and configuration characteristics for systems, structures and components.
Design configuration documents constitute the "Why" and the "What" of the plant.
These documents provide the technical bases for the various activities of design, 2
These categories are used only as a convenient framework to illustrate the design process.
Design is an iterative processm - as such, there will be times when process and output documents will be used as input documents.

l installation, operation, maintenance, and testing, all of which affect plant configuration. The level of control required for any document is dependent on the extent to which its information is relied upon by any activity, and, the potential of that activity to adversely affect plant configuration as required by design and          l licensing bases.
Control of design configuration documents is required by 10CFR50 Appendix B and ANSI N45.2.11. Control of design documents covers activities that could affect the content of design documents , and their use in plant activity. These activities include preparation, revision, review, approval, release, distribution, maintenance and retrieval.
Design input Documents Design input documents identify system design criteria. Sources of design                !
criteria include regulatory documents, applicable industry codes and standards,          l and static ("non-living") documents such as closed Design Change Packages i
and correspondence. Design input information may be contained in such                    l documents as Design Basis Documents, Upper Level Documents, System                       :

Generally, these procedures specify the administrative and quality assurance policies and practices, assign responsibilities, address activities of interest to many plant departments and detail the performance of particular activities.
The issuance of these documents is controlled to ensure that the most recent revisions are used to perform plant activities. The documents are issued in a controlled manner to specified locations or individuals and inserted into the appropriate manuals in a timely manner.
Changes to the documents are controlled to ensure that the information contained in the document is accurate. Procedures dictate the requirements for changing a plant document. The revision process requires the appropriate technical, safety evaluation and interdepartmental reviews and approvals before the document is issued for use.

CONTROL OF LICENSING DOCUMENTS:
FSAR Update The FSAR is periodically updated in accordance with 10CFR50.71(e) to include               l the effects of changes to the facility or procedures as described in the FSAR,             I safety evaluations performed in support of requested license amendments, and analyses of new safety issues performed at the request of the Commission.
The primary mechanism for initiating identification of FSAR changes is the 10CFR50.59 process. As noted in the description of Process Element #2, the                 i 50.59 process provides a convenient trigger point for FSAR updating since the              !
initial step of the 50.59 process requires that a facility or procedure change be          l evaluated to determine its impact on the FSAR. Having identified an impact to the FSAR, the responsible individual identifies any other potential FSAR changes, documents the proposed changes to the FSAR and transmits the proposed change (s) to the licensing organization.
Pmvided that no unreviewed safety question exists, the licensing organization makes an internal update to the FSAR following implementation of the proposed change. Periodically (on a nominal refueling cycle schedule, not to exceed 24 months), the accumulated internal changes to the FSAR are required to be transmitted to the NRC and other controlled document holders, and reflect facility changes up to a maximum of 6 months prior to the submittal date.

Technical Specifications Change Technical Specifications (and the broader category of the Operating License) are changed through application of the requirements of 10CFR50.90 and 10CFR50.91. A license amendment request is prepared by responsible personnel, describing the proposed change and addressing the standard "no significant hazards consideration" questions. Upon approval by the on-site and off-site safety review committees, the license amendment request is transmitted to the NRC for approval. Implementation of the proposed change is held pending NRC approval. This process also applies to any unreviewed safety questions identified during a 10CFR50.59 evaluation.

RBNP-027," Initiation of a Change to a Licensing Document" Technical Requirements Manual Change The Technical Requirements Manual (TRM) in general contains those requirements that have been relocated from the Technical Specifications or Operating License. Usually, relocation occurs due to implementation of a generic letter line item improvement or implementation of the improved technical specifications.
Initial relocation of a technical specification (and its consequent inclusion in the TRM) requires prior NRC approval under the provisions of 10CFR50.90 through a license amendment (as discussed above). Subsequent changes to material contained within the TRM are controlled through the 10CFR50.59 process (with the exception of a few unique TRM items that are changed through evaluation under 10CFR50.54(a)).

in order to ensure systems, structures, and components are available to perform          l their function (s), a Preventive Maintenance (PM) program has been established, covering three areas: predictive maintenance, periodic maintenance, and                  ;
planned maintenance.
* Predictive Maintenance:
Predictive maintenance involves continuous or periodic monitoring and diagnosis of equipment and components in order to forecast equipment             :
failure. Predictive maintenance results are used to trend and monitor            i equipment performance so that planned maintenance can be performed               I prior to equipment failure.

     . Periodic Maintenance Periodic maintenance involves activities accomplished on a routine basis, i;
such as operating hours or calendar time, and include any combination of external inspections, alignments or calibrations, internal inspections,               :
overhauls, and component or equipment replacements.
     . Planned Maintenance Planned maintenance involves activities performed prior to equipment failure. The activities can be initiated by predictive or periodic maintenance results, by vendor recommendations or by experience.

Calibration Performance Selected plant instrumentation is periodically calibrated to ensure it properly performs its intended function (s) and meets the range and resolution assumptions of the design basis. Calibration includes activities which check and set instrument range, setpoints, alarm functions, trip and isolation functions, etc.,
as appropriate. The frequency intervals for calibration activities are determined via the plant design basis and TS/TRM (as applicable) for the specific instrument and the function (s) performed.

i Performance monitoring is a set of processes that provide a feedback mechanism to ensure that the plant is performing in accordance with design basis and other assumptions. Performance monitoring processes are not utilized to introduce a permanent plant configuration change.
For this set of processes, our evaluation focus is on how the results of the monitoring activity are used to confirm that the plant performs consistent with the design basis. While we recognize that the reason for monitoring activities is founded upon the design and licensing bases, we have chosen to restrict our review to those process elements (Table 2) associated with the monitoring output:
: 4. Document update controls
: 5. Interface controls - for communicating the results of the monitoring,        !
: 6. Restoration controls - for restoring any plant configuration changes needed to perform the monitoring, and
: 7. Deficiency controls - for documenting and resolving any monitoring results which exceed acceptance criteria.

RBG-43668 Appendix B Page 1 of 3 APPENDIX B CORRECTIVE ACTION PROCESS EFFECTIVENESS ELEMENTS As discussed in Section VI [ Response to Question (a)], in order to make a judgment about the completeness of the process (es) that could affect corrective action, it is necessary to identify such processes and determine the configuiation management elements that are necessary for effective corrective action. Unlike configuration management, corrective action is a single process, therefore, (as noted in Section Vill, Response to Question (d)) it is only necessary to identify the process effectiveness elements in order to make a judgment about the completeness of the corrective action process.
Table 3 in Section Vill identified the corrective action process elements necessary for an effective corrective action process. Each element in the table is described below. (It is worthwhile to note that reportability, which is specifically addressed in Question (d), is' discussed as a subset of Element #1, below.)
Element #1 - Problem identification Conditions adverse to quality (10CFR50 Appendix B, Criterion 16) must be formally identified and documented for processing within the corrective action program. The threshold for problem identification should be sufficiently low that if an individual is in doubt as to whether to document a condition, it will be documented.
The initial problem identification step triggers other related processes:
      . Operability - A degraded or non-conforming condition should receive a prompt determination of operability (i.e., a judgment as to whether the affected structure, system or component can perform its safety function).
      . Reportability - A condition adverse to quality should be evaluated to -
determine if the condition is reportable to the NRC in accordance with various regulations. The primary regulations governing reportability are 10CFR50.72 (1 and 4 hour verbal reports),10CFR50.73 (Licensee Event Reports) and 10CFR21 (Basic Component Defects). Other regulations (e.g.,10CFR50.46) also contain reporting requirements which must be considered.

:             As part of the problem identification element, it should be determined if the
:             condition constitutes a significant condition adverse to quality (within the
]             meaning of 10CFR50, Appendix B, Criterion 16). This determination will be used
;             in the next element to decide upon the depth of cause analysis necessary.
i An important aspect of the problem identification element is a determination of generic applicability - i.e., is the deficiency unique or could it apply to related components or processes? If generic, the scope of subsequent corrective action must take this into account.
Element #2 - Cause Determination Those deficiencies that are determined to be a significant condition adverse to quality receive a formal root cause evaluation. The technique chosen for the evaluation (e.g., barrier analysis, HPES, etc.) is a function .of the type of deficiency to be addressed. The root cause evaluation (including problem statement, analysis and root cause(s)) is documented and distributed for management review.
Those deficiencies that are determined to not be a significant condition adverse to quality receive an apparent cause determination. Apparent cause is determined by the assigned individual and documented on the appropriate deficiency document.
Element #3 - Corrective Actions Corrective actions are developed to address both the immediate deficiency and the root / apparent cause(s). With respect to cause, corrective actions are intended to prevent recurrence of the identified cause(s). Once developed, corrective actions are documented on the associated deficiency document.
Corrective actions should address generic implications (if any) through an expansion of activity beyond the immediate deficiency. Priority of corrective action implementation is addressed through development of an implementation schedule commensurate with the safety significance of the deficiency. Each action is assigned to a responsible individual and/or group, and acknowledged.
Element #4 - Trackina Corrective actions, once identified and assigned, are tracked to completion. A tracking system exists that can be periodically updated concerning corrective action status, and can identify near-due and past-due corrective actions.
