EPRI Utility Requirements Document
For
Next Generation Nuclear Plants

Welcome to the Utility Requirements Document (URD). The purpose of the URD is to present a clear, complete statement of utility requirements for their next generation of nuclear plants.

The URD consists of a comprehensive set of design requirements for future Light Water Reactors (LWRs). The requirements are grounded in proven technology of 50+ years of commercial U.S. and international LWR experience. Furthermore, the URD builds on this LWR knowledge base, addressing design and operational issues which originally existed in today's generation of plants, while incorporating optimized features from industry R&D which assure a simple, robust, more forgiving design.

Revision 11 is comprised of 4 volumes:
  Volume 0:
  Volume I:
  Volume II:
  Volume III:
Executive Summary
Policy and Summary of Top-Tier Requirements
Evolutionary Plants
Passive Plants
