Division Spotlight
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

INL’s new innovation incubator could link start-ups with an industry sponsor
Idaho National Laboratory is looking for a sponsor to invest $5 million–$10 million in a privately funded innovation incubator to support seed-stage start-ups working in nuclear energy, integrated energy systems, cybersecurity, or advanced materials. For their investment, the sponsor gets access to what INL calls “a turnkey source of cutting-edge American innovation.” Not only are technologies supported by the program “substantially de-risked” by going through technical review and development at a national laboratory, but the arrangement “adds credibility, goodwill, and visibility to the private sector sponsor’s investments,” according to INL.

The automated startup of a boiling water reactor (BWR) plant is discussed. A startup procedure and a logic representation of the operational guidance given in current BWR plants are examined. Based on these examinations, a knowledge representation of the sequential operations is proposed. Plant startup is a process in which various plant functions are brought in to establish an operational plant state. Based on this understanding, the relationships between plant functions can be used to deduce a BWR plant operation procedure. Finally, the proposed knowledge representation is evaluated using a prototype system, and it is shown that the representation is very effective in the startup of an automated BWR plant even if abnormalities arise during operation.
