Argonne’s METL gears up to test more sodium fast reactor components
Argonne National Laboratory has successfully swapped out an aging cold trap in the sodium test loop called METL (Mechanisms Engineering Test Loop), the Department of Energy announced April 23. The upgrade is the first of its kind in the United States in more than 30 years, according to the DOE, and will help test components and operations for the sodium-cooled fast reactors being developed now.

This paper proposes a fuzzy method of evaluating horizontal nuclear proliferation risk for more efficient use of the International Atomic Energy Agency's (IAEA's) integrated safeguards (IS). The nuclear proliferation risk Rj of nation j is defined as (1 - j) × (1 - j), where j is the probability of nation j maintaining only peaceful nuclear activities for at least 1 yr, is the probability that the IAEA's IS detect indicators of nuclear explosive device (NED) acquisition activities, and j is the probability that the international community will force nation j to abandon these activities after the indications are detected.Because j is equal to and replaces the concept of nuclear nonproliferation credibility used in previous studies, this paper uses a method of deriving this credibility and converting it into j, which is evaluated using trapezoidal fuzzy numbers. Case studies of four nations currently under the IS reveal that the probability of IS detection of indicators of NED activity can be reduced by several tens of percent for some countries without exceeding the upper limit of horizontal nuclear proliferation risk that the international community had accepted in the past.Therefore, depending on the value of nuclear proliferation risk determined using the fuzzy method, the IAEA will be able to use its limited resources efficiently by reducing unnecessary expenditures for some nations under the IS and reallocating those resources to inspections of other nations without increasing the risk of proliferation.
