1.6 RISK ASSESSMENT APPLICATION PROCESS: SECTION 3
Scction 3 of this Standard describcs requirements for a process that shall be used to dcterminc the capability of a Level 3 analysis to support various applications. The use of a Level 3 analysis will be different from application to application. This Standard, which is application non-specific. is concerned only with the capability of the analysis to support risk-informed decision-making. For a specific application, the technical capabilities may be evaluated against this Standard. rcquircnwnt by requirement on an as-nccded basis to support the application, rather than by evaluating whether the Level 3 analysis as a whole has all of the appropriate technical capabilities to meet this Standard.
1.7 LEVEL 3 CONSEQUENCE ANALYSIS TECHNICAL REQUIREMENTS: SECTION 4
Section 4 provides specific SRs for each HLR for each technical element delined for a Level 3 analysis.
1.8 RISK ESTIMATION (RI): SECTiON 5
Section 5 provides requirements that integrate Level 3 analyses with the results from the Level 1/2 analyses to obtain a characterization of the overall risk including the determination of uncertainty.
1.9 CONFIGURATION CONTROL: SECTION 6
Section 6 provides requirements for configuration control of a Level 3 analysis (i.e.. maintaining and upgrading a site) plant-specific analysis) to a degree sufficient to support an application for which it may be used
1.10 PEER REVIEW: SECTION 7
Section 7 of this Standard provides the general requirements for a peer review to determine II the mehodology and its implementation meet the SRs of the lll.Rs for each technical element in this Standard
1.11 DOCUMENTATION REQUIREMENTS
Specific documentation requirements are defined in detail in each technical element in Sections 4 and 5.
1.12 USE OF EXPERT JUDGMENT
This paragraph provides requirements for the use of expert judgment outside of the Level 3 analysis team to a specific technical iSSLic. Guidance from NUREG’C’R-6372 131 and NUREG-1563 [41 may be used to
meet the requirements in this paragraph. Other approaches or a combination of these may also be used. A review of expert aggregation methods, the different types of consensus, and issues with resolving disagreements among experts can he found in Appendix J of NURE(ICR-6372 131. A series of NURE(i documents (Le.. NIIREGICR244 151, NUREG.CR-6523 161. NUREG/CR-6526 Ill. NURF.GCR-6545 181. NURF.GCR-6555 191. and NUREG/CR-6571 1101) summarizes a joint NRC and Commission of European Communities study pertaining to expert judgment for a variety of technical issues related to consequence analysis. This series documents both the process and the results of the expert elicitations performed.
