The purpose, as written, implies that it is solely an audit against the requirements of Section 4. A key objective of the peer review is to ensure when evaluating the PRA against the technical requirements, the "quality" (i.e., strengths and weaknesses) of the PRA; this goal is to be clearly understood by the peer review team. Further, the statement that "the peer review need not assess all aspects of the PRA against all requirements" could be taken to imply that some of the requirements could be skipped. |
Clarification |
...another purpose of the peer review is to determine the strengths and weaknesses in the PRA. Therefore, the peer review shall also assess the appropriateness of the assumptions. The peer review need not assess all aspects of the PRA against all requirements in the Technical Requirements Section of each respective Part of this Standard; however, enough aspects of the PRA shall be reviewed for the reviewers to achieve consensus on the assessment of each applicable supporting requirement, as well as on the adequacy of methodologies and their implementation for each PRA Element. |

As written, there does not appear to be a minimum set. The requirement as written provides "suggestions." A minimal set of items is to be provided; the peer reviewers have flexibility in deciding on the scope and level of detail for each of the minimal items. |
Clarification |
The peer review team shall use the requirements... of this Standard. For each PRA element, a set of review topics required for the peer review team are provided in the subparagraphs of para. 6.3. Additional material for those Elements may be reviewed depending on the results obtained. These suggestions are not intended to be a minimum or comprehensive list of requirements. The judgment of the reviewer shall be used to determine the specific scope and depth of the review in each of each review topic for each PRA element. |

The word "significant" is used in many places throughout the Appendix. For example, the term "significant changes in scope or capability" is used to classify a change as a PRA upgrade, rather than a PRA maintenance. The term "significant change in risk insights" is used to indicate when a focused peer review is suggested even for what is nominally classified as a PRA maintenance. While what is meant by the former is clarified in the examples, what constitutes a "significant change in risk insights" needs to be defined and added to the defined terms in Section 1-2. |
Clarification |
Add to list of definitions -- Significant change in risk insights: Whether a change is considered significant is dependent on the context in which the insights are used. A change in the risk insights is considered significant when it has the potential to change a decision being made using the PRA. |

As written, it could be inferred that a newly developed method would not be considered an upgrade. |
Clarification |
. . . "new" should be interpreted as new to the subject PRA even though the methodology in question has been applied in other PRAs and includes newly developed methods that have been used in the base PRA by the analyst. It is not intended to imply a newly developed method. This interpretation . . . |

An "internal review" is recommended in several places. This recommendation is made instead of an "outside" peer review. It needs to be made clear that this internal review is a type of "peer review" and should follow the process and requirements for the peer review requirements. |
Clarification |
(d) In the context . . . A focused review would be warranted. When performing an internal review, the objective is to assess that the change to the PRA was correctly performed. In performing this assessment, the reviewer should use as guidance those applicable requirements in the standard. |

It is assumed that a change to the base PRA that involves a calculation using the same computer code is a PRA maintenance type change rather than a PRA upgrade type change. This assumption would only be valid if the calculation does not involve any new assumptions and the same analyst is performing the calculation. |
Clarification |
Change: . . . . using the same computer code that was used for the prior calculations, given the calculation does not involve any new assumptions and the calculation is performed using the same guidance. NOTE: the words "that was used for the prior calculations" do not appear in Example #8, staff clarification includes these words in Example #8. |

1-A.3, Example 18 |
Changing the definition of core damage without changing the thermal- hydraulic methodology may result in changed success criteria which could change the accident progression delineated by the accident sequences. It is not a foregone conclusion that this is a simple change to the PRA model. It needs to be reviewed to ensure that the resulting changes are appropriate. Further, what would be a significant change is open to interpretation, and "would be prudent" is not as strong as "should." |
Clarification |
Discussion and/or Alternative Recommendation: While this change may not be a "new methodology," it could result in changing the success criteria with implications for the development of accident sequences, and potentially on the HRA (through timing), data, and quantification. If this change leads to a significant change in risk insights, a focused peer review should be performed |

This assumes that the "important" human actions are of the same nature as the new ones being added and utilize the ASEP method in the exact same manner. This cannot be assumed. |
Clarification |
Rationale: If it can be shown that the previous "important" human actions fully utilized the ASEP method, and that any deficiencies by the analyst were corrected, then, if there is no significant impact on risk insights, this change falls into ....... |

The first example makes an assumption that the hourly failure rate is applicable for all operating conditions. |
Clarification |
...Thus, fbus at power = 1×10-7/hr * 8760 hrs/yr * 0.90 = 7.9×10-4/reactor year. In the above example, it is assumed the bus failure rate is applicable for at- power conditions. It should be noted that initiating event frequencies may be variable from one operating state to another due to various factors. In such cases, the contribution from events occurring only during at-power conditions should be utilized. |

For Cat II, it is not acceptable to just note that a flood-induced failure mechanism is not included in the scope of the internal flooding analysis. Some level of assessment is required. |
Qualification |
Cat I: For the SSCs identified in IFSN-A5, IDENTIFY the susceptibility of each SSC in a flood area to flood-induced failure mechanisms. INCLUDE failure by submergence and spray in the identification process. EITHER: ASSESS... by using conservative assumptions; OR NOTE that these mechanisms are not included in the scope of the evaluation. Cat II: For the SSCs identified in IFSN-A5, IDENTIFY the susceptibility of each SSC in a flood area to flood-induced failure mechanisms. INCLUDE failure by submergence and spray in the identification process. ASSESS qualitatively the impact of flood-induced mechanisms that are not formally addressed (e.g., using the mechanisms listed under Capability Category III of this requirement), by using conservative assumptions. |

The notes states this requirement is a starting point for selection of mitigating equipment, and that an iterative process will provide the completeness with respect to Table 1-1.3-1, which specifies that the significant contributors be included in the model. The requirement should represent the end result, not the beginning point. Although the definition of failure mode in Part 1 includes spurious operation, it is worth explicitly including since it is an important issue. |
Qualification |
Cat II: IDENTIFY Fire ... and INCLUDE fire risk-significant equipment from the internal events PRA. NOTE-ES-B1-7: The gradation across ... the Fire PRA (other equipment can be assumed failed in the worst possible failure mode, including spurious operation). This will tend ... |

There is a concern with the way in which the term "significant"™ has been used. It is ambiguous as to whether the reference is to the total CDF, the internal events CDF, or the fire CDF. In order to avoid ambiguity, it is necessary to have a definition of the term "significant." The terms "significant accident sequence," "significant accident progression sequence," "significant basic event," "significant cutset," and "significant contributor" are defined in Part 1 within the context of the hazard group, so that in Part 3, they should be interpreted as being measured with respect to the fire risk. |

Spectral shapes used to evaluate in-structure SSC"™s must include the effects of amplification from both local site conditions and SSI. Based on IPEEE reviews, certain UHS shapes used for CEUS were not appropriate for the screening purpose. |
Clarification |
NOTE HA-G1: The issue of which spectral shape should be used in the screening of structures, systems, and components (SSCs) and in quantification of SPRA results requires careful consideration. For screening purposes, the spectral shape used should have amplification factors, including effects from both local site conditions as well as soil- structure interaction, such that the demand resulting from the use of this shape is higher than that based on the design spectra. This will preclude premature screening of components and will avoid anomalies such as the screened components (e.g., surrogate elements) being the dominant significant risk contributing components. Additional discussion on this issue can be found in Ref. 17. In the quantification of fragilities and of final risk results, it is important to use as realistic a shape as possible. Semi-site specific shapes, such as those given in NUREG-0098, have been used in the past and are considered may be adequate for this purpose, provided that they are shown to be reasonably appropriate for the site [42]. The uniform hazard response spectrum (UHS) is acceptable for this purpose if it can be shown that the UHS shape is appropriate for the site. unless evidence comes to light (e.g., within the technical literature) that these UHS do not reflect the spectral shape of the site-specific events. Recent developments [42] indicate that these spectral shapes are not appropriate for CEUS sites where high frequency content is dominant at hard rock sites. |

Peer Review for SM |
-------------------- |
The staff does not endorse the material in this Part of the standard, and as such, does not have a position (i.e., no objections, no objection with clarification, or no objection with qualification) on any of the material contained in Part 10 of the standard. However, it should be noted, that consistent with the Commission endorsed phase PRA Quality Initiative, all risk contributors that cannot be shown as insignificant, should be assessed using a PRA (as defined in Section C.1) to support risk- informed licensing actions. |
