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.

A proactive approach to reactor vessel aging management
Unit 2 at the Prairie Island nuclear power plant near Red Wing, Minn., underwent an outage in fall 2023, which included extensive work on the reactor vessel using a novel approach to replace baffle-former bolts and lower radial clevis insert bolts. The work relied on extensive analysis beforehand to determine which bolts to replace such that only the new bolts were structurally credited for performance of their safety function. This proactive approach eliminated the need for costly contingencies associated with inspections.

An analysis of the prospects for the use of atmospheric optical communication lines at industrial nuclear energy installations, including thermonuclear (fusion) reactors and energy facilities with on-site fuel reprocessing plants, was carried out. It is shown that modern atmospheric communication terminals make it possible to implement high-speed data exchange within the perimeter of energy complexes, as well as to provide an external backup communication channel protected by use of quantum key distribution technology. The absence of the need to lay special cables through limited-access areas to organize high-speed data transmission provides a significant advantage of atmospheric communication systems over any wired communication systems. A methodology is presented for assessing the feasibility of using atmospheric optical communications at nuclear facilities, and based on long-term meteorological observations in the area where ITER (International Thermonuclear Experimental Reactor) is located, graphs of the availability of atmospheric communications are constructed. The high prospects of using atmospheric laser communication at nuclear and fusion facilities are shown.
