Safety classification and special design criteria development application guide. Safety Analysis Report Update Program

摘要

This document is a pilot application guide to the identification of Safety class Items (SCIs) and the development of associated special design criteria. It is intended to interpret, apply, and supplement, where necessary, DOE orders and guidance to make a practical, coherent, risk-based framework for the safety analyst to use identifying SCIs in conjunction with Facility Safety Evaluation Teams (FSETs) for existing facilities and design teams for new and modified facilities. Three categories of Safety Class Items are identified in this guide: SC-1, SC-2, and SC-3. SC-1 items are required primarily to protect the health and safety of the off-site public, SC-2 items are required solely to protect the health and safety of on-site personnel, and SC-3 items are required solely to protect the health and safety of the facility operators. These definitions are taken from DOE/OR-901, Guidance for Preparation of Safety Analysis Reports (ref. 3), Appendix C, ''Guidelines for Determination of Safety Class Items.''
