Mining Existing Assets for Software Product Lines

John Bergey, Liam O’Brien, D.R. Smith

Mining of existing assets offers an organization the potential to leverage all, or part, of its cumulative system investments, and thus represents a critical practice area in implementing a software product line. However, there are significant risks in achieving success because of …

D.R. Smith

American National Standard, {open_quotes}Administrative Practices for Nuclear Criticality Safety,{close_quotes} American National Standards Institute/American Nuclear Society (ANSI/ANS)-8.19-1996, addresses the responsibilities of management, supervision, and the criticality safety staff in the administration of an effective criticality safety program. Characteristics of operating procedures, process evaluations, …

Criticality safety and international standards

D.R. Smith

There appears to be a worldwide increase in interest in international standards. Indications are that international standards will tend to replace or overshadow national standards. An illustration of this tendency was seen recently. During the recent (February 1996) meeting of the International …

American National Standard administrative practices for nuclear criticality safety, ANSI/ANS-8. 19

D.R. Smith

American National Standard Administrative Practices for Nuclear Criticality Safety, ANSI/ANS-8.19, provides guidance for the administration of an effective program to control the risk of nuclear criticality in operations with fissile material outside reactors. The several sections of the standard address the responsibilities …

Economic impacts of criticality safety decisions

D.R. Smith

Nuclear criticality safety has been recognized as the dominant economic influence on many large-scale fissile material processing operations. Recognizing that the cost of converting plutonium scrap to high-purity metal can be as great as $15/g, it becomes obvious that overly conservative safety …
