In providing the “end user” all of these aspects, the first edition has been revised appropriately to be consistent with the current 2004 Codes. Contributors of the first and second volumes had taken immense pains to carefully update their write-ups to include as much of the details that they could provide. Significant changes can be seen in Sections II, III, VIII and XI with repercussions on Sections I, IV, V, VII, IX and X. Thus, these consequences had been picked up by the contributors to bring their write-up up to date. Similarly changes of Power Piping (B31.1 Code) and B31.3 (Process Piping) have also been updated. Included in this edition is a third volume that addresses the crit- ical issues faced by the BWR and PWR Nuclear facilities such as BWR Internals, PWR Reactor Integrity, and Alloy 600 related issues. With the aging of the Nuclear Plants, the regulators per- spective can be meaningful, and this has been addressed by experts in this area. In today’s industrial spectrum the role of Probabilistic Risk Analysis has taken an important role and this volume has a chapter contributed by recognized authorities. With the increased use of computer–related analytical tools and with ASME Codes explicitly addressing them, a chapter has been devoted to the Applications of Elastic Plastic Fracture Mechanics in ASME Section XI Code. ASME Codes are literally used around the world. More importantly the European Community, Canada, Japan and UK have been increasingly sensitive to the relevance of ASME Codes. In this second edition, experts conversant with these country Codes had been invited to detail the specifics of their Codes and cross- reference these to the ASME Codes. Public Safety more so than ever before, has become extremely relevant in today’s power generation. Experts hade been invited to provide a perspective of the regulations as they emerged as well as discuss the salient points of their current use. These include the transportation of radioactive materials and the new ASME Section XII Code, Pipe Line Integrity and pertinent topics involved in decommissioning of nuclear facilities. K. R.

PREFACE TO THE SECOND EDITION

This edition continues to address the purpose of the first edition to serve as a “Primer” to help the user weave through varied aspects of the ASME Codes and B31.1 and B31.3 Piping Codes and present a summary of specific aspects of interest to users. In providing the “end user” all of these aspects, the first edition has been revised appropriately to be consistent with the current 2004 Codes.
Contributors of the first and second volumes had taken immense pains to carefully update their write-ups to include as much of the details that they could provide. Significant changes can be seen in Sections II, III, VIII and XI with repercussions on Sections I, IV, V, VII, IX and X. Thus, these consequences had been picked up by the contributors to bring their write-up up-to- date. Similarly changes of Power Piping (B31.1 Code) and B31.3 (Process Piping) have also been updated.
Included in this edition is a third volume that addresses the crit- ical issues faced by the BWR and PWR Nuclear facilities such as BWR Internals, PWR Reactor Integrity, and Alloy 600 related issues. With the aging of the Nuclear Plants, the regulators per- spective can be meaningful, and this has been addressed by experts in this area. In today’s industrial spectrum the role of Probabilistic Risk Analysis has taken an important role and this volume has a chapter contributed by recognized authorities. With the increased use of computer–related analytical tools and with ASME Codes explicitly addressing them, a chapter has been devoted to the Applications of Elastic Plastic Fracture Mechanics in ASME Section XI Code.
