This report describes a thermally-induced electrical failure (THIEF) model's ability to predict the behavior of power, instrument, and control cables during a fire. The model is intended to be incorporated as a subroutine for deterministic fire models, and it is of comparable accuracy and simplicity to the activation algorithms for various other fire protection devices (e.g., sprinklers, heat and smoke detectors). THIEF model predictions are compared to experimental measurements of instrumented cables in a variety of configurations, and the results indicate that the model is an appropriate...

The U.S. Nuclear Regulatory Commission (NCR) 2011-2012 Information Digest provides a summary of information about the NRC and the industry it regulates. It describes the agency's regulatory responsibilities and licensing activities and also provides general information on nuclear-related topics.

NRC's Offices of Nuclear Regulatory Research (RES) and Federal and State Materials and Environmental Management Programs (FSME) organized this Workshop on Engineered Barrier Performance Related to Low-Level Radioactive Waste, Decommissioning, and Uranium Mill Tailings Facilities. The workshop was held August 3-5, 2010 at the U.S. Nuclear Regulatory Commission (NRC) Headquarters Auditorium, 11545 Rockville Pike, Rockville, Maryland. The Workshop was coordinated with the States (i.e., Texas, South Carolina, Utah, Colorado, Washington, and New York), Tribal Nations (Navajo, Umatilla and Nez...

This document is a supplemental safety evaluation report for the license renewal application for Prairie Island Nuclear Generating Plant, Units 1 and 2, as submitted by Nuclear Management Company (NMC), LLC.

This safety evaluation report (SER) documents the technical review of U.S. Advanced Boiling Water Reactor (ABWR) Aircraft Impact Assessment (AIA) application by the U.S. Nuclear Regulatory Commission (NRC) staff.

This report describes eight events that NRC identified as AOs during Fiscal Year (FY) 2010. One event involved radiation exposure to an embryo/fetus. The other seven events occurred at NRC-licensed or regulated medical institutions and are medical events as defined in Title 10, Pt 35, of the Code of Federal Regulations (10 CFR Part 35).

This EIS includes the analysis by the NRC and Corps staff that considers and weighs the environmental impacts of building and operating two new nuclear units at the CPNPP site and at alternative sites, and mitigation measures available for reducing or avoiding adverse impacts.

This report provides technical details applicable to access control methods and technologies commonly used to protect facilities licensed by the U.S. Nuclear Regulatory Commission. It contains information on the application, use, function, installation, maintenance, and testing parameters for access control and search equipment and the implementation of protective measures that support access control. This information is intended to assist licensees in designing, installing, employing, and maintaining access control systems at their facilities.
