STATEMENT OF WORK Task Order - 13 TITLE: Individual Plant Examination (IPE) Reviews, Internal Events Human Reliability Analysis Only (Pilgrim 1)

DOCKET NUMBER: 50-293 NRC PROJECT MANAGER: John H. Flack, RES (301-492-3979)

NRC TEAM LEADER FOR PILGRIM 1: Ed Chow, RES (301-492-3984) ,

I TECHNICAL MONITOR: John H. Flack, RES (301-492-3979)

PERIOD OF PERFORMANCE: April 14,1993 to April 13,1994 1 l

1 BACKGROUND On November 23, 1988, the NRC issued Generic Letter 88-20 " Individual Plant Examination," which stated that licensees of existing plants should perform a .

systematic examination (IPE) to identify any plant-specific vulnerabilities to:

severe accidents, and to report the results to the Commission. The purpose of  !

the IPE is to have each utility (1) develop an overall appreciation of severe l accident behavior; (2) understand the most likely severe accident sequences at l its plant; (3) gain a quantitative understanding of the overall probability of core damage and radioactive material releases; and (4) reduce the overall probability of core damage and radioactive releases by modifying procedures and hardware to prevent or mitigate severe accidents. All IPE submittals will be reviewed by the NRC Staff to determine if licensees met the intent of Generic Letter 88-20.

OBJECTIVE The purpose of this contract is to solicit contractor support in order to l enhance the NRC review of licensees' IPE submittals. This contract includes the examination and evaluation of the Pilorim 1 IPE submittal, specifically with regard to the human reliability analysis. The contractor review will be of limited scope and consist of a " submittal only" review. The " submittal only" review and gathering of associated insights will help the NRC staff determine whether the licensee's IPE process met the intent of Generic Letter 88-20, or whether a more detailed review is warranted.

1

~

l By identifying the IPE's strengths and weaknesses, extracting important insights and findings, and providing a comparison to staff reviewed and '

accepted PSAs (e.g. NUREG-1150, PSAs identified in NUREG-1335 Appendix B), it is expected that the NRC will be in a better position to expeditiously evaluate the licensee's IPE process. To provide support under this contract, the contractor will search for obvious errors, omissions and inconsistencies ,

in the IPE submittal as described in the work requirements listed below. ,

WORK RE0VIREMENTS AND SCHEDULE The contractor will perform a " submittal only" review of the Pilarim I human reliability analysis. The contractor shall provide the qualified specialists  !

and the necessary facilities, materials, and services to carry out such a review. The contractor will utilize NRC review guidance documents for detail ,

and reference as well as other interim guidance provided by the NRC Technical Monitor. The contractor is not expected to make a plant / site visit in order to perform this review.  :

Subtask 1. Review and Identification of IPE Insichts Perform a " submittal only" review of human reliability analysis and identify important IPE insights by completing the NRC IPE Data Summary Sheets. (The sheets identify the information that will be entered into the IPE insights and findings data base.) During the review, focus on the areas described below under " Work Requirement." The contractor will note any: (1) inconsistencies l between methodology employed in the IPE submittals and other PSA studies, (2) ,

inconsistencies between the submittal's IPE findings and findings stemming i from other PSAs (See NUREG-1335, Appendix B). The contractor will respond explicitly to each work requirement by noting important review findings l including any IPE strengths and weaknesses. The contractor will also list i under each listed work requirement, any questions (back to the licensee) i associated with the lack of appropriate information or need for further clarification. j Work Reauirement 1.1. Perform a General Review of the Human Reliability

' Analysis Check the following:

1.1.1 The IPE submittal is essentially complete with respect to the type of information and level of detail requested in the IPE Submittal Guidance Document, NUREG-1335. List any obvious omissions. i 1.1.2 The employed HRA methodology is clearly described and justified l for selection. l 1.1.3 The methodology (including the human action taxonomy) employed is capable of identifying important human actions, and contains a discussion of the most important human actions and errors.

1.1.4 The IPE submittal employed a viable process to confirm that the IPE represents the as-built, as-operated plant.

1.1.5 The HRA had been peer-reviewed to help assure the analytic l techniques were correctly applied.

Work Reauirement 1.2. Review the Most Likelv Secuences that Could Occur at the Plant ,

Check the following:

1.2.1 The accident sequences appropriately considered human actions consistent with NUREG-1150 and other NRC accepted PSAs (see table NUREG-1335 Appendix B). ,

1.2.2 The accident sequences screened out because of low human error ,

(see NUREG-1335, Section 2.1.6.6) appears appropriate, based on HRA techniques employed.

Work Reauirement 1.3. Review the Ouantitative Nature of the IPE Submittal Check n ' following:

1.3.1 The employed human error probability (HEP) screening values appear capable of screenirq in significant human errors.

1.3.2 The IPE developed human error probabilities (HEPs) for significant human actions, or provided rationale for using screening values.

1.3.3 Sources of generic human reliability data used in the IPE were identified and rationale for their use provided. Generic human error probability (HEP) data were modified using plant-specific Performance Shaping Factors (PSFs) as appropriate, and rationale r provided for selection of taployed PSFs.

1.3.4 The recovery method is clearly described and credit for recovery actions appears justified. l Work Reauirement 1.4. Review the IPE Acoroach to Reducina the Probability of Core Damaae or Fission Product Release  ;

Check the following:  ;

1.4.1 The IPE analysis appears to support the licensee's definition of I vulnerability, and that the definition provides a means by which  ;

the identification of potential vulnerabilities (as so defined) l and plant modifications (safety enhancements) is made possible.

1.4.2 The identification of plant improvements include human-related  !

plant modifications (e.g., procedures and training), and proposed 1 modifications are reasonably expected to enhance human reliability ,

and plant safety.

Work Reouirement 2.0. Comolete Data Sheets Complete the NRC data summary sheets and note lack of information, as ,

appropriate, j Subtask 2. Prepare Technical Evaluation Report Prepare a report with the outline provided below.

I. Introduction l

Provide a brief overview of the IPE review, the scope and depth as  :

l appropriate. Place emphasis on review areas identified as being important and rationale for importance, i.e., found to be important in l' i

1 other PSAs of similar design. Discuss any important or unique plant characteristics. Note plants with similar features and any important i insights stemming from other relevant PSA studies. j II. Contractor Review Findings  ;

Explicitly address each work requirement element listed above under I subtask 1, " Review and Identification of IPE Insights." Discuss any strength or weakness so identified and significance with respect to the overall IPE effort. Identify any additional information (in the form of questions back to the licensee) which would be important to the review ,

effort. Indicate why the information is important for closure..

III. Overall Evaluation and Conclusion i l

Summarize the " submittal only" review conclusions based on the i information submitted and significance of IPE strengths and weaknesses. l IV. IPE Evaluation and Data Summary Sheets Attach the completed IPE Data Summary Sheets.

REPORT RE0VIREMENTS Technical Reports The contractor will submit to the NRC technical monitor four copies of the Technical Evaluation Report (TER) six weeks after the initiation of this  !

contract. Copies will include one hard copy and one 3.5" computer diskette - l version (Wordperfect 5.1 or other IBM PC compatible software acceptable to the NRC IPE Team Leader). The TER shall summarize all findings, results, and ,

conclusions in the areas examined in the format described under Task 2. If the contractor finds that the licensee's IPE .is obviously deficient in any of i the areas examined, the technical monitor should be notified in advance.

Deficient or weak areas should be clearly documented in the technical evaluation report. In addition, if the contractor finds that there are i 4

i

~

. i specific areas that need additional in-depth review, the Team Leader should be notified of the areas, and provided with the rationale for subsequent review.  ;

l The contractor shall meet with the NRC staff after submittal of th' TER to  !

present and discuss its findings, results, and conclusions.

The NRC staff shall review the TER submittal, prepare questions for the licensee, and submit a package for the licensee's response within two to three weeks after the contractor's presentation. The licensee is given at least 60 days to respond to NRC's questions. Upon receipt of the licensee responses, the NRC staff will review the responses against the TER within one to two ,

months after the receipt of the responses to determine the need for further clarification. If further clarification is required, the contractor shall i provide NRC with their response. j 1

The contractor should allow one day of effort to provide NRC with quick-turn- ,

around reviews of licensee's comments or responses to the TER and/or questions.

BUSINESS LETTER REPORT The contractor shall provide monthly progress reports in accordance with the requirements of the basic contract.
