==Dear Mr. Noonan:== | |||
As requested, enclosed herewith is the revision bar annotated copy of revision 2 of Appendix E of the CPRT Program Plan. Please replace the copy of the Appendix E transmitted to you by my {{letter dated|date=June 6, 1986|text=June 6, 1986, letter}} with the attached. | |||
Revision 2 of Appendix E was necessitated for the following reasons: | |||
- General editing to eliminate repetitious wording. | |||
- Title change to more appropriately reflect what the Appendix addresses. | |||
- Revised definition of QA/QC program deficiency to more precisely describe the criteria that a QA/QC program deviation must satisfy in order to be classified as a deficiency. | |||
Sections B.5 and B.6 in Revision 2 were moved forward from Sections C.5 and C.7 in Revision 1, because these sections more appropriately belong in Section B rather than Section C of the appendix. | |||
- Title change of Section C from " Evaluation Process" to | |||
" Follow-up Activities". The new title is a better descriptor of the activities described therein. | |||
- Section D " Closure" was added for completeness. | |||
Should you have any further questions, please contact Mr. John Beck or myself. | |||

APPENDIX E I | |||
CPRT Procedure For The Resolution l Of Discrepancies Identified by the CPRT A. PURPOSE The purpose of this procedure is to provide instructions for the l resolution of discrepancies identified by the CPRT. | |||
The resolution processes described in this Appendix were primarily developed and designed to address discrepancies identified by the CPRT during the implementation of the ISAPs and DSAPs developed for the CPRT self-initiated investigatory efforts. In order to ensure consistency throughout the CPRT program, these processes will also l | |||
> be applied in the reporting of the results of the CPRT | |||
. investigatory efforts for ISAPs and portions of DSAPs that were i developed to respond to concerns specifically identified by External Sources. | |||
I Additional information related to the development, approval and documentation of corrective actions for all deviations or deficiencies (both specific and programmatic) identified by the CPRT is provided in Appendix H to the CPRT Program Plan. | |||
~ | |||
j B. CLASSIFICATION j | |||
l Discrepancie,s identified by the CPRT are classified into categories of relative significance in order to determine the appropriate follow-up activities required to resolve and close them. | |||
The following definitions have been established for use in classifying identified discrepancies. The basis for classification | |||
- of each discrepancy shall be documented. | |||
! 1. Design Adequacy All design discrepancies are classified as observations. | |||
deviations or deficiencies, depending upon whether the design | |||
' error resulted in a failure to meet design criteria and depending on the safety significance of any failures to meet i design criteria. The definitions employed in this area by the CPRT are as follows: | |||
i i (a) Design Discrepancy | |||
' Any identified error related to design inputs, implementing documents and outputs for safety-related | |||
: structures, systems or components that could have an i | |||
adverse impact on the adequacy of their design. | |||

B. CLASSIFICATION (Cont'd) | |||
(b) Design Observation Any identified design discrepancy that has been determined to not constitute a design deviation. | |||
(c) Design Deviation Any identified design discrepancy that has been determined to constitute a verified failure to meet a design commitment or specification. In this regard, design commitments include regulatory requirements, FSAR cosimitments, other licensing commitments, code commitments or other project-specific design criteria or commitments. | |||
(d) Design Deficiency Any identified design deviation that has been determined to be safety-significant. | |||
(e) Safety-Significant | |||
" Safety 7significant", for purposes of the CPRT Program , is defined to mean that the identified | |||
< discrepancy, if uncorrected, would result in the loss I of capability of the affected system, structure or component to perform its intended safety function. For purposes of the CPRT Program, credit is not allowed for redundancy at the component, system, train or structure level. | |||
(f) Programmatic Design Deficiency A set of related design discrepancies that have been | |||
! determined to constitute an adverse trend that is programmatic in nature. | |||
i r | |||
This definition, which is employed in the CPRT Program for purposes of sample expansion, is more restrictive than that usually applied 1 | |||
to the term " safety-significant" for regulatory purposes or in j common parlance, in that it ignores redundancies that do exist in real life. (Compare 10CFR50, Appendix A (Introduction, " Single | |||
' Failure"); 10CTR50.55(e)(1) .] Identification of a deficiency as | |||
" safety-significant" for purposes of the CPRT Program, therefore, is not necessarily equivalent to a statement that, in fact, the | |||
: deficiency, if uncorrected, would have resulted in unsafe < | |||
operation. | |||

: 2. Construction Adequacy All construction discrepancies are classified either as deviations or deficiencies, depending upon the safety significance of the discrepancy. The definitions enployed by the CPRT in this area are as follows: | |||
(a) Construction Deviation Any identified discrepancy related to construction or installation of safety-related hardware that has been determined to constitute a verified failure to construct or install a safety-related structure, system or component in accordance with safety-significant attributes and triteria contained in design drawings and specifications or installation procedures / | |||

(b) Construction Deficiency Any identified construction deviation that has been determined to be safety-significant. | |||
(c) Safety-Significant See B.I.(e) and associated footnote for definition. | |||
(d) Programmatic Construction Deficiency A set of related construction deviations that has been determined to constitute an adverse trend that is programmatic in nature. | |||
: 3. Testing Program Adequacy All testing discrepancies are classified either as deviations or deficiencies, depending upon the significance of the discrepancy. The definitions employed by the CPRT in this area are as follows: | |||
(a) Testing Deviation Any verified failure to meet a testing program commitment, regulatory requirement or a project specific testing commitment. In this regard, commitments include FSAR commitments and other licensing commitments. | |||

FSAR commitments or other licensing commitments. | |||
(b) QA/QC Program Deficiency Any identified QA/QC program deviation meeting one or more of the following criteria: | |||
- Inadequacy of a QA/QC program element such that substantive revision of the program or other corrective action is required to bring it into compliance with the regulatory requirements, FSAR commitments or other licensing commitments; or i | |||

: 5. Adverse Trends A trend is a set of related observations and/or deviations having attributes that reflect a discernible commonality. | |||
Examples of possible commonalities include: | |||
- The individual, group of individuals cr organization performing the safety-related activity; and | |||
- The program requirements, procedures or controls governing the performance of the safety-related activity. | |||
A trend is considered to be adverse if it is determined that the identified pattern or commonality is likely to have resulted in the occurrence of an undetected deficiency in the affected area, population or stratum. Adverse trends are also referred to as programmatic deficiencies. | |||
Each trend identified by the CPRT will be evaluated to determine whether it is adverse (unless it is processed as an | |||
; unclassified trend). CPRT Review Team Leaders are responsible for performing such evaluations and for making such determinations within their areas of responsibility. | |||
4 The nature and extent of these evaluations will vary depending upon the nature of the identified trend and the information | |||
, already available regarding the implications of the trend. | |||
i Considerations in this regard include the extent to which: | |||
! - The boundaries of the trend have been identified; | |||
- The underlying cause and/or contributing causes of the trend have been identified; I | |||

- 5. Adverse Trends (Includina Unclassified Trends) and Programmatic Deficiencies An investigation of the root cause and/or contributing causes of the trend will be conducted.
The generic implications of the trend will be evaluated. This evaluation must be of sufficient scope to provide reasonable assurance that there are no undetected deficiencies within the affected area, population or stratum.
Appropriate corrective actions for any additional deviations or deficiencies identified during the evaluation of generic implications must be defined.
. Appropriate corrective action to preclude recurrence in the future must be defined.
The results of these activities will be documented and retained in the CPRT working fiAas.
