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.

Webinar: MC&A and safety in advanced reactors in focus
Towell
Russell
Prasad
The American Nuclear Society’s Nuclear Nonproliferation Policy Division recently hosted a webinar on updating material control and accounting (MC&A) and security regulations for the evolving field of advanced reactors.
Moderator Shikha Prasad (CEO, Srijan LLC) was joined by two presenters, John Russell and Lester Towell, who looked at how regulations that were historically developed for traditional light water reactors will apply to the next generation of nuclear technology and what changes need to be made.

Lithographed wire targets have recently been fabricated for use as backlighter targets for experimental campaigns at the OMEGA laser facility. These experiments required targets with 10-m gold wires lithographed onto plastic. A process was developed using lithography to make these targets via sputter coating and liquid solution removal of the resist. One of the challenges overcome in developing this target was depositing the gold so that it would strongly adhere to the plastic. The quality of the lithographed targets was much better than targets made by other methods, such as gluing or thermal techniques. The lithographed targets were straighter, which is important in order to minimize the emission spot size at shot time. The lithographed targets also did not have problems with plastic or glue covering the wires, which can also reduce target emission, another challenge for gluing or thermal techniques. Lithography also allows a large number of similar targets to be made at once and cut out to the individual size needed, and a wide range of complex patterns or designs are possible using this technique.
