“A international group of neutrino physics specialists (including Prof. John G. Learned of UH Manoa), who are interested in reducing the spread of nuclear weapons have written a paper suggesting a method for monitoring the interior of nuclear reactors at the North Korean Yongbin nuclear site using ethereal subatomic particles called neutrinos. A letter on this technique was published in the November 9th edition of  Science magazine. A paper on their method has been posted to the on-line physics preprint archive http://arxiv.org/abs/1811.04737
