<p></p> <p><b>New page</b></p><div>==Task Overview==<br /> <br /> ===Objective===<br /> The objective is to document the SPRA methodology used and the results of the study in a manner that is useful for peer review, updating and applying to risk informed applications.<br /> <br /> ===Purpose===<br /> This section describes a modular notebook structure for documenting an SPRA.<br /> <br /> ===Guidance===<br /> The individual notebooks may include, but are not limited to, the following:<br /> * Seismic Methods and Results Notebook<br /> :- Describes the key elements of the SPRA model process including PSHA, internal event PRA, success criteria, walkdown observations, SSC fragilities, guidelines, treatment of consequential hazards and the quantitative results.<br /> :- The Seismic Methods and Results Notebook could be expanded to develop separate notebooks to document Consequential Hazards and the Quantitative Results if preferred by the SPRA analyst.<br /> * Seismic Initiating Events Notebook<br /> :- Documents the analysis of the initiating event categories from seismic hazard intervals, frequencies, error factors and ground motion calculations<br /> * Seismic Event Tree Notebook <br /> :- Explains the event tree sequence quantification of postulated accident scenarios in the SPRA.<br /> * Seismic Human Reliability Notebook<br /> :- Develops and recommends the best estimate of HEPs for use in the SPRA.<br /> * Seismic Fragility Modeling Notebook<br /> :- Evaluates fragility frequencies from the failure of an SSC and explains how these are modeled into the SPRA<br /> * Seismic Plant Walkdown Notebook<br /> :- Documents plant-specific observations and aspects that would support the reasonableness of the seismic impacts to be incorporated into the SPRA.<br /> <br /> ==Supplemental Guidance==<br /> <br /> ===Related Element of ASME/PRA Standard===<br /> Part 5, Seismic Hazard Analysis (SHA) <br /> <br /> Part 5, Seismic Fragility Response (SFR)<br /> <br /> Part 5, Seismic Plant-Response (SPR)<br /> <br /> ===EPRI Guidance===<br /> &#039;&#039;Seismic Probabilistic Risk Assessment Implementation Guide&#039;&#039; ([https://www.epri.com/research/products/000000003002000709 3002000709]). Appendix F provides example outlines for SPRA documentation.<br /> <br /> ===Other Guidance===<br /> (none noted)</div>
