1.0 GENERAL I.I BACKCROUND AND PURPOSE The Nuclear Regulatory Commission (NRC) issued a letter on July 9,1982 which requested that Consumers Power Company (CPC) provide for an independent assessment of the design adequacy of the Midland plant. CPC responded to this request on October 5,1982 by submitting an outline of the scope of a proposed independent review program. A public meeting was held on October 25,1982 at the NRC's Bethesda, Maryland offices to discuss details of the proposed program, the scope of which included on evaluation of the Midland Unit 2 Auxiliary

() Feedwater (AFW)' system. During this meeting, the NRC requested that the scope of the independent design assessment program be expanded, including on assessment of the quality of construction. The NRC requested that CPC identify three candidate systems for scope expansion based upon their contribution to plant risk, from which one system would be selected.

CPC responded to NRC by a letter dated December 3,1982 which identified the l Standby Electric Power system (diesel generator), Safeguards Chilled Water system and Containment Isolation system as candidate systems. A public meeting was held on February 8,1983 at Midland, Michigan to discuss details of the program related to the evaluation of the AFW system and to provide status.

l On March 22, 1983 the NRC selected the Standby Electric Power system and the Control Room HVAC system for scope expension. Proposed elements of the scope of evoluotion for these systems as well as the APN system were discussed at another public meeting held on April 13, 1983 at the NRC's Bethesda, Maryland p offices.

mh j TERA Corporation has been selected by CPC to scope, manage, and implement l the Midland Independent Design and Construction Verification (IDCV) Program.

By a letter dated May 3,1983, the NRC approved the selection of TERA. The selection is based upon the firm's technical qualifications, experience, and independence from the Midiond project. Such independence includes all individuals who may contribute to the IDCV Program.

This project instruction, or Engineering Program Plan (the Plan), has been established to outline the scope, philosophy of review, methodology Independence requirements, organizction, control, documentation, reporting, cnd quality assurance requirements for the Midland IDCV Program, t

(3 q.)

The IDCV approach selected is a review and evaluation of a detailed " vertical slice" of the Midland project with a focus on providing an overall assessment of the quality of the design and the constructed plant. Therefore, the primary emphasis of the IDCV evaluation is on the end results of the design and construction process and not on on evaluation of the process itself which is typical of the more common quality assurance audit. The " vertical slice" constitutes a carefully selected sample of three safety systems from which the results of the IDCV may be extrapolated to other similarly designed and l constructed systems. Thus, the IDCV is intended to provide the necessary assurance to CPC, NRC, and the pblic that the Midland Plant is designed and constructed such that it is capable of functioning in accordance with its safcty design bases and that applicable licensing commitments have been properly implemented.

-l REV.: 2 DATE: 5/18/83 Construction Verification Program 1 (PAGE 3 of 145 Pf:EPARED BY: g APPROVED BY I.2 OVERVIEW OF IDCV SCOPE The Midland IDCV consists of two major components: the Independent Design Verification (IDV) Program and the Independent Construction Verification (ICV)

Program. The Unit 2 Auxiliary Feedwater (AFW) system, the Standby Electric Power (SEP) system and the Control Room Heating, Ventilating and Air Conditioning (CR-HVAC) system related to control room habitability have been selected as applicable samples of the design engineering and construction efforts I at the Midland plant. The AFW system was selected by TERA based upon the system selection criteria discussed. in Section 1.3 of this Plan. The SEP and control room HVAC systems selected by the CPC and NRC have a sufficiently  :

V high profile for each of these criteria to justify their selection.

The scope of review corresponds directly to the design and construction chains,  ;

addressing major activities and outputs of the various contributing engineering and construction disciplines. Accordingly, the products of the design and j construction process, from concept to installation, hydros, functional and I preoperational testing and turnover will be evaluated. Interfaces between CPC, )

Babcock and Wilcox (B&W), the nuclear steam system supplier (NSSS) vendor, Bechtel, the architect-engineer (A-E), and other contractors will be identified and evaluated relative to such items as the proper transfer and interpretation of l design or construction information. l l

Figure 1.2-1 shows the inter-relationship between the Midland design and construction process and the Midland IDCV program. The following figures present the IDCV scope for the AFW, SEP and CR-HVAC systems in the form vf matrices which identify the initial level of review and evaluation in each design l

pj APPROVED B Figures Design Construction System Verification Verification AFW l.2-2a, 2b I.2-3 SEP l.2-4o, 4b I.2-S CR-HVAC l.2-6a, 6b I.2-7 It should be noted that the scope of technical review is dynamic and subject to change as more emphasis will be given to specific review creas that meet prescribed criteria. These criteria are documented in Section 3.1.2 of this Plan.

Accordingly, the review matrices generally represent the initial IDCV " sample".

On April 13,1983, a change of the AFW system initial sample was effected. This (a') change is noted on Figures 1.2-2a,1.2-2b and 1.2-3.

l.3 SYSTEMS SELECTION CRITERIA The selection of the auxiliary feedwater system was based upon the following six criteria:

e importance to Safety - The system should have a rela-tively high level of importance to the overall safety of l the Midland Plant.

1 inclusion of Design and Construction Interfaces - The e

system should be one which involves multiple interfaces among engineering and construction disciplines as well as design and construction organizations, such as the NSSS vendor, architect engineer, constructor, and subtier con-tractors. The system should also be one where design or construction changes have occurred and thus provide the ability to test the effectiveness of the design and con-struction process exercised by principal internal and

(-)/

t external organizations or disciplines in creas of design or construction change.

FAGE 15 of 145 p l i (,,, .- m L;_

W e Ability to Extrapolate Results - The system should be sufficiently representative of other safety systems such that the design criteria, design and construction control and change processes are similar so that extrapolation of findings to other systems con be undertaken with confi-dence.

. Diverse in Content - The major engineering and con-struction disciplines should all have input to the design of the system.

e Sensitive to Previous Experience - The system should be one which includes design or construction disciplines or interfaces which have previously exhibited problems and thus a test of the system should be indicative of any generic condition, o

i I ( e Ability to Test As-Built Installation - The system con-figuration should be sufficiently completed that the as-built configuration can be verified against design.

i

! The AFW system was selected after consideration of a number of other candidate systems. The Midland Plant probabilistic risk assessment (PRA) was utilized as a tool to assess the relative importance to safety of plant systems on the basis of their contribution to overall plant risk. The profile for this criterion as well as each of the other five criteria is sufficiently high for the AFW, SEP and CR-HVAC systems to justify their selection.

l.4 INDEPENDENCE REQUIREMENTS The Midland IDCV program will be conducted in accordance with the

" independence" criteria documented in a letter from Nunzio J. Palladino, Chairman, NRC, to the Honorable John D. Dingell, Chairman, Committee on Energy and Commerce, United States House of Representatives, dated O

and Electric Company's Diablo Canyon project; however, it is being applied to the l Midland IDCV program and the reader should interpret the words PG&E or Diablo i Canyon to mean CPC or Midland, respectively. The following criteria are excerpted from Enclosure 3 of this letter:

"The competence of the individuals or companies is the most important factor in the selection of an auditor. Also, the companies or individuals may not have had any direct previous involvement with the cctivities at Diablo Canyon (Midland) that they will be reviewing.

In addition, the following factors will be considered in evaluating the question of independence:

l in

() 1) Whether the individuals or companies involved had been previously hired by PG&E (CPC) to do similar seismic (delete seismic) design work.

2) Whether any individual involved had been previously employed by PG&E (CPC) (and the nature of the employment).

1

3) Whether the individual owns or controls significant amounts of PG&E (CPC) stock.

4) Whether members of the present household of individuals involved are employed by PG&E (CPC).

5) Whether any relatives are employed by PG&E (CPC) in a management capacity.

i In addition to the above considerations, the following l procedural guidelines will be used to assure independence:

l l) An auditable record will be provided of all comments on draft or final reports, any changes made as a result of such comments, and the reasons for such changes; orr the consultant will issue only a final report (without prior licensee comment).

v l 2) NRC will assume and exercise the responsibility for I

serving the report on all parties."

The individuals taking part in the Midland IDCV program meet the preceding i criteria and have signed a statement attesting to this fact. I TERA Corporation is under contract to CPC to provide the engineering services necessary to complete the Midland IDCV program. Prior to this contract, TERA has never been under contract to CPC.

1 The contract requires TERA to maintain an auditable record to document the l process leading to Findings as well as meetings to discuss Findings. Section 4.0 of this Plan addresses documentation and protocol requirements governing l external communications which have been developed to meet obligations of the l

() contract and NRC requirements. The protocol will be conducted in accordance l with the requirements documented in a letter from James G. Keppler, l Administrator, NRC Region Ill to James W. Cook, Vice President, CPC dated l

March 28,1983, as interpreted by TERA.

1 Section S.0 of this Plan addresses the report generation process, during the IDCV program to report Findings and at its conclusion as a final report. TERA will maintain an auditable record of all comments on the draft final report.

including the interrelationships between the organizations and suborganizations l participating in the Midland project. Next, the design bases in the form of l

regulatory requirements and design criteria are identified and reviewed in parallel with a review of project design and construction related experience.

The design bases review provides an overall understanding of the plant and system design. The project design and construction experience review ensures that the IDCV program encompasses previously identified problem creas to verify that these have been adequately addressed and that they do not exist elsewhere in the same or similar form.

For the systems, components, and structures identified in Sections 3.l.3 through O 3.1.5 and 3.2.3 through 3.2.5, detailed information which documents the implementation of the design and construction commitments will be identified, reviewed, and evaluated. The IDCV review and evaluation process will be documented in accordance with the procedures addressed in Section 4.0 of this Plan. The reporting of Findings including the disposition of items potentially leading to Findings will be reported in accordance with the precedures addressed in Section 5.0 of this Plan. The IDCV will be conducted in accordance with applicable provisions of 10 CFR 50, Appendix B, which are addressed in Section 6.0 of this Plan.

l 3.1 INDEPENDENT DESIGN VERIFICATION METHODOLOGY ANSI N45.2.11 defines design verification as the " process of reviewing, conform-ing, or substantiating the design by one or more methods to provide assurance that the design meets specified inputs." Design inputs include design bases or criteria, regulatory requirements, codes and standardstand other design commit-g l LJ

ments. The IDV includes a determination of the design inputs; an evaluation of their accuracy, consistency, and adequacy; and an evaluation of the implementa-tion of these commitments. The emphasis will be on making a determination of the overall quality of the design and an assessment of its compliance with licensing commitments. The review approach has been designed to be introspective in making this overall quality assessment by integrating the many design inputs and licensing commitments. This integrated assessment will ensure that all parameters have been considered which are important for the system in meeting its functional requirements.

Checklists have been prepared for each of these categories to aid IDCV reviewers in the implementation of their review. These checklists are discussed in section 3.l.6.

3.1.1.1 Review of Design Criteria and Commitments An identification and review of the design criteria and commitments concerning each specific design crea will be performed. This review category provides the (o

)

assurance that all necessary design inputs are considered in the IDV. The results of this review of design criteria and commitments are then used in subsequent stages where appropriate. The review of design criteria and commitments begins

with an identification of appropriate criteria for the system. Such criteria may l

3.1.1.2 Review of implementing Documents l

Implementing documents are those design documents which translate the design inputs into working level documentation. Typically, implementing documents include design criteria documents, project procedures, standard design practices, l specific plant design basis documents, drawings, and calculations.

Therefore, the objective of the review is to determine the existence and general reasonableness of the documentation and whether the documentation correctly reflects the design inputs. Design outputs are defined as documents such as drawings, specifications, and similar materials defining technical requirements for the fabrication, installation, or construction of the system.

The design output documents are reviewed for the application of the design criteria and commitments as part of the check of drawings and specifications.

3.1.l.3 Check of Calculations and Evaluations O When specified, a detailed check of calculations and evaluations is made (i.e.

inputs, assumptions, methodology, outputs, etc.). This activity follows the review of design criteria and commitments and the review of implementing documents. The check may take several forms, ranging from a number-by-number detailed mathematical check to a review and evaluation of outputs for reasonableness. The overall presentation of the sampled calculations and evaluations will also be reviewed to verify that all steps are clearly presented and consistent throughout. The IDV reviewer may, at his discretion, choose to conduct an alternative calculation as a means of confirming his judgment on the adequacy of the design calculation or evaluation. Where computer programs were used in the analysis, the reviewer will verify that appropriate inputs have been used in the calculation, and that the appropriate outputs have been identified. Additionally, it will be necessary to determine that the computer programs used have been verified in accordance with appropriate verification procedures.

mQ 3.l.l.4 Confirmatory Calculations or Evaluations For selected areus, confirmatory calculations or evaluations will be performed.

Generally, these evaluations will be made to confirm judgements relative to the review of creas which are suspect to the IDCV reviewer; however, " blind" confirmatory calculations will be undertaken in pre-selected areas to independently verify the original design calculations. Such confirmatory calculations will be performed by obtaining the necessary input data and independent specification of calculation or evaluation objective. The reviewer I

will select and apply the appropriate techniques to achieve the end results. Such calculation methods will be performed without benefit of first reviewing the l C) existing design calculational method, in order to preserve the " blind" nature of this approach, it will be necessary that a person other than the reviewer of the implemsting documents perform the confirmatory calculation er evaluation.

The confirmatory calculation or evaluation will be performed under procedures appropriate for the type of caiculation or evaluation being performed. To the extent appropriate, the calculation or evaluation will be equivalent to that initially performed. After completion of the confirmatory calculation or evaluation, a comparison between the original calculation and the confirmatory l methods will be made to determine whether differences exist. If differences occur, a determination will be made to assess whether these differences are due to the inherent nature of the calculation methods chosen or due to errors.

l For example, differences may result due to the selection by the originator of simplifying or conservative assumptions. In the event that the original calcula-tion is more conservative than the confirmatory calculation and meets design basis acceptance criteria, no further action will be necessary. On the other n

V hand, if the confirmatory calculation uses more conservative methods, a check of the original calculation will be made to determine whether the difference in degree of conservatism is appropriate.

3.1.l.5 Check of Drawings and Specifications Where appropriate, design outputs such as drawings and specifications will be reviewed and checked to assure that they accurately and consistently reflect that which has been called for in design documents such as calculations or engineering evaluations. Drawings and specifications will also be reviewed to determine whether design change notices and field change notices have been C incorporated. In cases where several related drawings exist, o cross-comparison among drawings w"' be made. Additioncily, a review will be made of correspondence with vendors to determine the existence of deviations from the specifications and the approval by the design organization of such changes.

3.1.2 BASES FOR SAMPLE SELECTION The systems selection criteria which are documented in Section 1.3 of this Plan also apply to the selection of specific structures or components to be reviewed I

within each design area of the IDV, including the depth of review in each design area. As a rule, the selection is based upon engineering judgment, as statistical l techniques are considered to be largely inappropriate for a design verification program. Senior members of the project team with requisite experience are responsible for selecting the sample and determining its size. This process provides grecter assurance than a random sampling plan since the initial IDV l sample is purposely biased towards typical problem areas. Furthermore, the o

When combined with a listing of each of the design creas (or topics), a matrix is formed which can be utilized to direct the conduct of the IDV effort for each system in the program. This matrix is shown on Figures 1.2-2a and 1.2-2b for the AFW system. A set of "X" marks are shown which indicate the review scope appliccble to each design area. The criteria discussed in Sections 1.3 and 3.1.2 of this Plan were incorporated to develop the initial matrix. The design creas of the IDV review matrix for the AFW system are divided into three major divisions: AFW System Performance Requirements, Q AFW System Protection Features, and Structures that House the AFW System.

The design areas addressed within each of these major divisions are discussed in Sections 3.1.3.1, 3.1.3.2, and 3.1.3.3 of this Plan, respectively. The initial review scope as documented in Revisions 0 and I of this Plan has been modified based upon meeting one or more of the criteria documented in Section 3.1.2. This change is indicated on Figures 1.2-2a and 1.2-2b by a circled "X" for items deleted from scope and by the symbol "*" for items added to scope.

Because the AFW system sample selection interfaces with other systems, it is

( necessary to define the boundaries for items within the scope of the IDCV. In general for the AFW system, the selection was made to include all components identified as being part of the AFW system on Bechtel P&lD drawing M439 sheets 3A, revision 9, and 3B, revi.sion 10.

In view of the fact that the design process involves a great number of individuals and organizations who may have contributed to the project engineering aciivi-ties, it is necessary to define a reasonable set of limits on the scope of the IDV.

Criteria were established by the project team to define the end points of the design chain applicable to this project. The majority of the design was performed by Bechtel. However, portions of the design mcy have been performed or affected by work performed by other organizations including, but not limited to, Babcock & Wilcox (B&W), engineering contractors, and equipment vendors. For the purposes of the verification program, the following limitations i were applied. The information obtained by Bechtel from B&W does not receive, as part of the IDV program, an independent evaluation of the process by which p

y) B&W developed its data. The verification program verifies that data obtained from B&W are consistent and reasonable based upon engineering judgment. If the B&W data are suspect, additional investigation into the causes may be warranted. Equipment vendors are reviewed to verify that the documents with which they were supplied are accurate and current and that the results of their design efforts conform with the specified requirements given to them by Bechtel or CPC. Vendor documentation will be reviewed to determine that his product does, in fact, meet applicable requirements of the specifications. In the event that deviations are determined to exist, the appropriate IDCV Program reporting procedures will be applied. For engineering contractors, the scopes of work applicable to these contractors will be determined and, in general, they will be treated as if they were part of the Bechtel design organization. That is, they will not be treated like a vendor who is given a specification end is expected to deliver a product in conformance with that specification. They will be treated as part of a design organization which has similar responsibilities to other parts of the Bechtel project organization.

3.1.4 DEFINITION OF REVIEW SCOPE FOR THE STANDBY ELECTRIC POWER SYSTEM The categories of review identified in section 3.1.1 are also applicable to the review of the Standby Electric Power (SEP) system. Similarly, the criteria discussed in sections 1.3 and 3.1.2 were incorporated to develop the initial design verification matrix shown on Figures 1.2-4a and 1.2-4b. The design areas (or topics) of the IDV review matrix for the SEP system are somewhat different from those for the AFW system, consistent with the differences in the functions and physical configuration of these systems. The review philosophy, matrix concepts and organization remain the same. The design areas for the SEP O sxstem review matrix are divieed rete three major divisioms: SEe Sxstem Performance Requirements, SEP System Protection Features, and Structures -

that House the SEP System. The design areas addressed within each of these major divisions are discussed in sections 3.1.4.1, 3.l.4.2 and 3.l.4.3 of this Plan, respectively. As previously mentioned, the identified initial review scope is subject to change depending upon whether the criteria documented in section 3.1.2 have been met.

Because the SEP system sample selection interfaces with other systems, it is necessary to define boundaries for items within the scope of the IDCV.

The SEP system as defined in the IDCV program includes four major elements:

the diesel generator (DG) and its support systems; the power distribution system (PDS); the preferred 120V ac power system (AC) and the 12SV de power system (DC). Continuity with the AFW system review is emphasized by drawing the boundaries of evaluation for the PDS and the two low voltage AC and DC systems as they service the AFW system. The PDS boundaries are drawn at DC-82-13

3.1.5 DEFINITION OF REVIEW SCOPE FOR THE CONTROL ROOM HVAC SYSTEM The categories of review identified in section 3.l.1 are also applicable to the review of the Control Room HVAC (CR-HVAC) system. Similarly, the criteria discussed in section 1.3 and 3.1.2 were incorporated to develop the initial design verification matrix shown on Figures 1.2-6a and 1.2-6b. The design areas (or d topics) of the IDV review matrix for the CR-HVAC system are somewhat different from those for the AFW or SEP systems, consistent with the differences in the functions and physical configuration of these systems. The review philosophy, matrix concepts and organization remain the same. The design creas for the CR-HVAC system review matrix are divided into three l major divisions: CR-HVAC System Performance Requirements, CR-HVAC System Protection Features and Structures that House the CR-HVAC System.

l The design creas addressed within each of these major divisions are discussed in

! sections 3.l.5.1, 3.1.5.2 and 3.1.5.3 of this Plan, respectively. As previously mentioned, the identified initial review scope is subject to change depending upon whether the criteria documented in section 3.1.2 have been met.

Because the CR-HVAC system sample selection interfaces with other systems, it is necessary to define boundaries for items within the scope of the IDCV. In general the CR-HVAC system sample selection boundaries include the Control Room Area Ventilation System (CRAVS), its support systems and components I

(] important to control room isolation and habitability during accident conditions; either radiological or chemical.

. 3 l.7 PLAN FOR ADDITIONAL SAMPLING AND VERIFICATION Additional sampling or verification within the scope of the IDV or outside the scope into other syster will be conducted if discrepancies are found. The level of additional sampling or verification will be based upon the nature of the discrepancy. In all cases when discrepancies are found, on introspective evaluation will follow to identify the extent and root cause. The root cause may either be random or systematic (generic). The additional review will attempt to verify whether the discrepancy is restricted to the specific system, component, or structure under review; restricted to work by a specific design organization; or if the discrepancy cuts across many interfaces and applies to similarly

( designed systems, components, and structures. As a rule, mathemctical errors l will not precipitate additior,al sampling and verification unless these are found in l significant numbers, leading to significant deficiencies or a compounding of errors. Judgement in making this assessment will be required on case-by-case basis.

As necessary, additional sampling or verification within the scope of the system sample selection boundaries identified in sections 3.1.3, 3.1.4 and 3.l.S of this Plan will be undertaken by TERA and approved internally. All such action; will be documented in the Monthly Status Report. Additional sampling outside this scope is considered a substantive issue and will be discussed between TERA, CPC cnd NRC prior to initiation.

In other words, the methodology described in the previous sections and applied to the ICV review of the AFW system will also, to the extent practical, be applied to the SEP system and CR-HVAC system.

Consistency in application of the review methodology in the crea of construction

() verification is as important as the scope of the review itself. By providing a consistent reference against which to gauge the construction process, a clear and precise picture of trends, discrepancies, and efficiencies in the Midland I construction process will be made more easily discernible. Thus, to establish the necessary common reference, the ICV review categories (section 3.2.1) and scope of review for the AF'N system (section 3.2.3) will also be applicable to the i review conducted of the SEP system. Modifications to the scope of review have been deemed necessary to. accommodate unique component or structural considerations pertinent to the SEP system. These unique considerations are provided in the following discussions and serve to supplement and modify the scope of activities previously described in sections 3.2.3.1 through 3.2.3.6. The scope of review for the SEP system is defined as follows and in the matrix provided in Figure 1.2-5.

a 3.2.7 PLAN FOR ADDITIONAL SAMPLING, VERIFICATION, AND TESTING The initici sampling and verification within the scope of the ICV is primarily based upon an evaluation of project generated documentation and data to verify the quality of both inaccessible (e.g. rebar placement) ced accessible systems, components and structures. The only exception to this is the incorporation of the NDE/ Materials Testing Program (reference sections 3.2.3.6 and 3.2.5.6) into the ICV scope. Under this program, data are collected by TERA as c confirmatory check. The quality of accessible items will be further verified by visual inspection or measurement as appropriate.

m

() Additional sampling or verification within the scope of the ICV systems or outside the scope into other systems will be conducted if discrepancies are found. As indicated in section 3.1.7, additional sampling or verification within the scope of the system sample selection boundaries identified in sections 3.l.3, 3.1.4 and 3.l.5 of this Plan will be undertaken by TERA, approved internally and documented in the Monthly Status Report. Additional sampling outside this scope is considered a substantive issue and will be discussed between TERA, CPC and NRC prior to initiation. Thn level of additional sampling or verification will be based upon the nature of the discrepency. In all cases when discrepancies are l found, on introspective evaluation will follow to identify the extent and root cause. The root cause may either be random or systematic (generic). The additional review will attempt to verify whether the discrepancy is restricted to the specific system, component, or structure under review; restricted to work by a specific construction organization; or if the discrepancy cuts across many interfaces and applies to similarly constructed systems, components, and l structures.

At first, the additional sampling and verification will be directed at an evaluation of additional dccumentation; however, if this documentation is incumplete or insufficient to identify the extent and root cause of discrepancies, further inspection or testing will be considered, as appropriate. If required to supplement internal resources, TERA may consider subcontracting a portion of any required inspection or testing services (e.g. non-destructive examination, materials testing, etc.) to o qualified organization that meets the independence requirements of Section 1.4 of this Plan.

Finding Resolution Reports document the conclusions of the review process which has been undertaken to resolve Findings and completely close out any concern about the Findings. Finding resolution may require additional analysis, design, or construction changes or procedural changes. Full resolution requires the identification of root cause and extent and a plan for corrective action if required.

gg Upon documenting his determination, the IDCV reviewer forwards a preliminary OCR Report er Potential Open item Report to his Lead Technical Reviewer (LTR) who reviews it with the project team (Project Manager and all LTRs). If the project team concurs with the reviewer's determination, the Potential Open item becomes an Open item which is formally controlled. The project team may resolve the Potential Open item, thus requiring reclassification of the item as a Resolved item and modification of the OCR Report reflecting this change. Both the Resolved item Report and superceded Potential Open item Report are then formally controlled. Alternatively, the LTR or project team may judge the identified deficiency as not being sufficiently serious to warrant classification as an OCR, yet it must be documented and corrected by CPC during the completion

Open items will be reviewed further by the review team until such a point that available information has been depleted. At this time, the IDCV reviewer wil!

prepare a Resolved item Report or a Confirmed item Report which documents his determination af ter further review. A Confirmed item is judged to be on apparent finding by the review team and requires further action to provide

Report will be issued and distributed to CPC, NRC, and outside parties on the IDCV service list.

S.2.3 INTERCHANGE OF INFORMATION The requirements of Section 4.2 are not intended to prohibit the informal interchange of information between IDCV personnel and external parties. These communications are essential to the IDCV review process. However, the items in Section 4.2 require documentation for the reasons cited. Furthermore, to preserve the independence of the IDCV review process, it is important that IDCV personnel maintain discretion in the dissemination of information bearing on n

() findings to outside parties until such a time that this information is final. This l procedure will prevent confusion and foster credibility to the IDCV review process.

5.3 IDENTIFICATION AND EVALUATION OF DESIGN / CONSTRUCTION PROBLEMS It is the duty of each IDCV team member to identify any deficiency known to him that may be significant to the public health and safety. He shall be permitted to conduct all reasonable evaluations necessary to make o determination of the significance of suspected items. IDCV personnel are l

responsible for presenting their conclusions in a manner that other technically qualified personnel may understand and independently verify. Furthermore, it is the responsibility of IDCV personnel to assess the significance of their conclusions and attempt to understand the extent and root cause of findings.

Any deviation from the above should be brought to the attention of the Project Manager.
