CONTINUING & CHANGING PRIORITIES OF ASME BOILER & C PRESSURE VESSEL CODES AND STANDARDS O N T From the writers of I N U “Companion Guide to the ASME Boiler & Pressure Vessel Code” K. R. Rao, Editor IN G & C This comprehensive work written by ASME Codes & Standards experts was originally published as part H A of Volume 3 of the Companion Guide to the ASME Boiler & Pressure Vessel Code. This fully updated and N CONTINUING & CHANGING PRIORITIES OF G expanded volume is now a stand-alone publication that addresses Continuing and Changing Priorities I N for the success of current and next generation Nuclear Reactors and Internals, License Renewal, Public G P Safety, and PRA issues. R ASME BOILER & I O R This book has four parts, the first dealing with continuing priorities of ASME Boiler and Pressure Vessel I T I Codes and Standards and the remaining three parts dealing with changing priorities of the Code. E S The first part has 13 chapters written by 15 distinguished code authorities with updated information O F pertaining to continuing priorities. Distinctive in this part is the inclusion of new contributors who have A PRESSURE VESSEL S added unique perspectives to the material that was first published in the third edition of the Companion M Guide. Likewise the authors who previously updated the material in the third edition have contributed E B additional information. A new chapter on “seismic protection for pressure piping systems” reflects the O I L importance of the topic especially in regard to aging nuclear reactors. E R CODES AND STANDARDS & Three distinctive parts of the book address changing priorities of ASME B&PV Codes and Standards. P R These are: “Changing Priorities;” “Lessons Learned;” and “Future Discussions.” E S In Part 2, “Changing Priorities,” there are nine chapters by 11 contributors who are not only Code experts S U K. R. Rao, Editor but also recognized authorities in the topics covered by them. Part 3, “Perspectives of Lessons Learned,” R E has eight chapters by 11 authoritative contributors who are also distinguished in the topics addressed by V E them. In light of the aging nuclear reactors in operation in the U.S. and around the world and the need S S for new reactors, it is appropriate to synthesize the expert experiences relating to selected topics. Part E L 4, “Future Discussions,” is the culmination of the current thinking process for the use of nuclear energy C O for power generation. This part has two chapters written by five authors with recognized expertise in the D E subject matter. S A N D A unique feature of this publication is the inclusion of all author biographies and an introduction that S synthesizes every chapter, along with an alphabetical listing of indexed terms.
