Research into the integrity of containment structures or vessels for nuclear power plants has been conducted around the world in those countries where nuclear energy is produced and provides, or is expected to provide, a significant portion of the domestic energy supply. While the contributions of each of these efforts to the understanding of the role of containment in ensuring the safe operation on nuclear power plants is important, the most comprehensive experimental effort has been conducted at Sandia National Laboratories, primarily under the sponsorship of the US Nuclear Regulatory Commission (NRC). This report describes the background and context for the more than 25 years of NRC-sponsored Containment Integrity Research at Sandia National Laboratories and summarizes the major results of the experimental efforts and the observations and insights gained from the analytical efforts.
An evaluation of the nuclear power plant regulatory basis is performed, as it pertains to those plants that are permanently shutdown (PSD) and waiting or undergoing decommissioning. Four spent fuel storage configurations are examined. Recommendations are provided for those operationally based regulations that could be partially or totally removed for PSD plants without impacting public health and safety.
This NUREG contains the improved Standard Technical Specifications (STS) for General Electric (GE) BWR/4 plants. Revision 3 incorporates the cumulative changes to Revision 1 and 2, which was published in April 1995 and April 2001, respectively. The changes reflected in Revision 3 resulted from the experience gained from license amendment applications to convert to these improved STS or to adopt partial improvements to existing technical specifications. This publication is the result of extensive public technical meetings and discussions among the Nuclear Regulatory Commission (NRC) staff and various nuclear power plant licensees, Nuclear Steam Supply System (NSSS) Owners Groups, and the Nuclear Energy Institute (NEI).
